APD Statement Regarding Arrest of Rosalinda Nuno Trevino
￼ FOR IMMEDIATE RELEASE July 7, 2020 Contact: Public Information Office, (512) 974-5017 APD Statement Regarding Arrest of Rosalinda Nuno Trevino APD is aware of a video that is circulating involving the arrest of 40-year-old Rosalinda Nuno Trevino for multiple hazardous traffic violations. Regarding Case# 20-1860985, on July 4, 2020, Austin Police Department Motor Unit Officers were riding their motorcycles behind a protest march to keep people safe from vehicular traffic. Ms. Trevino was driving a white SUV behind these motor officers. Ms. Trevino began to follow the officers very closely with her vehicle and honk her horn continuously. She drove through empty parking spaces and attempted to move her vehicle around the officers’ motorcycles. Officers told Ms. Trevino to stay behind their motorcycles to ensure the safety of the people marching. Ms. Trevino then stopped her vehicle, ran up to an officer and requested his badge number, which the officer provided. At the intersection of 2nd Street and Congress Avenue, Ms. Trevino started to honk the vehicle horn a second time and drove through a red light. Ms. Trevino then stopped her vehicle again and approached officers. Ms. Trevino was placed under arrest for the multiple hazardous traffic violations to include, running a red light, failure to yield the right-of-way to pedestrians, improper use of a horn and failure to maintain an assured clear distance. As a crowd began to form, officers moved Ms. Trevino to the front of an officer’s vehicle to conduct a search before transporting her to jail. While conducting the search, he advised Ms. Trevino that a female officer was not available. He conducted the search in front of a police vehicle where a vehicle camera could document and at least one other officer was present, as required by APD policy. Full APD Policy: https://www.austintexas.gov/sites/default/files/files/Police/General%20Orders.pdf APD Frisk/Search Training Video: https://youtu.be/XgdZBwQ-0Og Portions of APD Policy have been copied below with highlighted explanations for your convenience: 306.3.1 SEARCH PROTOCOL Nothing in this order supersedes officer safety tactics. (a) Officers will conduct person searches with dignity and courtesy. (b) Officers will conduct property searches in a manner that returns the condition of the property to its pre-search status as nearly as reasonably practicable. (c) Officers should attempt to acquire keys to locked property when a search is anticipated, and the time and effort required to gain the keys makes it a practicable option. (d) It is the responsibility of each individual officer to search a prisoner for weapons or contraband anytime he gains custody of that prisoner, regardless of whether the prisoner was previously searched by another officer. (e) When safety permits:
Officers should explain to the person being searched the reason for the search and how the search will be conducted.
2. When practical, an officer of the same gender should be called to the scene when officers believe the subject is concealing items in a sensitive area, such as evidence or narcotics in the groin, buttocks, or breast areas. This does not apply to items that pose an immediate threat to officer safety.
If a subject requests a search by an officer of the same gender, an attempt should be made to have a same gender officer conduct the search.
If a same gender officer is unavailable, the search should be conducted in front of a Mobile Audio Video (MAV) recording system, if available, or a second officer should be present.
If the gender of the individual needing to be searched comes into question, officers should respectfully inquire as to whether the individual identifies as transgender. When an individual self-identifies as transgender, officers will not question this identity absent articulable, compelling reasons, nor will an officer inquire about intimate details of an individual's anatomy to determine gender. Officers needing to search a person who has disclosed that, or the officer recognizes by prior knowledge, the individual is Transgender, Intersex, and/or Fender Non-Binary/Gender Non-Conforming (TIGN), should, when practicable, conduct the search based on the gender with which the individual identifies. (For example, a Female-to-Male individual should, when practicable, be searched by a male officer, or by a female officer who conducts an opposite gender search. A Male-to-Female individual should, when practicable, be searched by a female officer, or by a male officer who conducts an opposite gender search).
Officers will use the backside of their hands and fingers to frisk/search sensitive areas of the opposite gender to include the breast, crotch, and buttocks.
306.6 SEARCH INCIDENT TO ARREST The general authority to search incident to a lawful custodial arrest is not qualified or limited by the type of arrest. Objects of the search are weapons, evidence, and/or means of escape. (a) Persons:
When officers make a lawful arrest, they are permitted to conduct a contemporaneous search of the arrestee. Such a search safeguards the arresting officer and others nearby from harm while ensuring that the arrestee will not discard or destroy evidence.
It is entirely reasonable for arresting officers to search the area where the defendant might reach in order to grab a weapon or evidence.
306.9 FRISK (PAT-DOWN) FOR WEAPONS A frisk is a mere pat-down of the outer clothing, area, vehicle or container to which a detained person may have immediate access. The purpose of a limited weapons frisk after an investigatory stop is not to discover crime, but to allow the officer to pursue the investigation without fear of violence. An officer does not need to be absolutely certain that an individual is armed; the issue is whether a reasonably prudent person would justifiably believe that he or others were in danger. (a) Persons:
A frisk is a limited patting of the outer surfaces of a person's clothing in an attempt to find weapons. A frisk can only be used by officers when they justifiably stop someone and have a reasonable fear for their safety, the safety of the public, or when a cautious and prudent officer under the same or similar circumstances would conduct a pat-down.
Normally, officers cannot put their hands under the suspect's outer clothing until they feel something they reasonably believe is a weapon. If the outer clothing is too bulky to allow officers to decide if a weapon is concealed underneath, outer clothing such as overcoats and jackets may be opened to allow a pat down of the inner clothing, such as shirts and trousers.
Packages, purses, briefcases and other containers may be frisked during the stop.
The scope of a protective frisk is limited to persons and places within arm's reach of a concealed weapon or toward which the subject might lunge.
A trans person's measured take on the trans sports issue
So first of all this post was inspired by GGExMachina's brief statement on the issue:
For example, it is objectively the case that biological men have a physical advantage over women. Yet if someone points this out and suggests that transgender people shouldn’t be allowed to fight in women’s UFC, or women’s soccer or weightlifting competitions or whatever, suddenly you’re some kind of evil monster. Rather than saying that of course trans people shouldn’t be bullied and that we could perhaps have a trans olympics (like the Paralympics and Special Olympics), we are expected to lie.
I've found that this position is incredibly popular among liberals/left-leaning people, especially here on reddit. It seems like, once or twice a month, like clockwork, a thread stating more or less the same thing on /unpopularopinion or /offmychest will get thousands of upvotes. And while I completely understand the thought process that leads otherwise left-leaning people to come to such conclusions, I feel like the issue has been, broadly speaking, dishonestly presented to the general public by a mixture of bad-faith actors and people who have succumbed to the moral panic. And, as I've seen, there are plenty of people in this subreddit and elsewhere who are itching to be as supportive as they possibly can to the trans community but find themselves becoming very disillusioned by this particular issue. By making this post I hope to present a more nuanced take on the issue, not only in regards to my personal beliefs on what kinds of policies are best to preserve fairness in women's sports but also in regards to shining a light on how this issue is often times dishonestly presented in an attempt to impede the progression of pro-trans sentiments in the cultural zeitgeist.
Sex & Gender
The word "transgender" is an umbrella term that refers to people whose gender identities differ from those typically associated with the sex they were assigned at birth. According to the 2015 U.S. Transgender Survey, the approximate composition of "the trans community" in the United States is 29% Transgender men (Female-to-Male), 33% Transgender women (Male-to-Female), and 35% non-binary. (The remaining 3% were survey respondents who self-identified as "crossdressers", who were still included in the survey on the grounds of being gender non-conforming) While non-binary people, as a group, are probably deserving of their own separate post. the focus of this post will be on trans men and trans women. I will also be primarily focusing on transgender people who pursue medical transition with Hormone-Replacement-Therapy, as they are most relevant to the issue of sports. (Mind that while the majority of binary trans people fit into this camp, there is a sizable minority of trans people who do not feel the need to medically transition.) What do trans people believe about Gender? The views of transgender people in regards to Gender are actually pretty varied, although the most prominent positions that I've personally seen are best summed up into two different camps:
The "Trans-Medical" camp
Transgender people who fall into this camp usually consider Gender Dysphoria to be the defining factor of what makes somebody trans. The best way I can describe this camp is that they sort of view being transgender akin to being intersex. Only whereas an intersex person would be born with a disorder that affects the body, a trans person is born with a disorder that affects the brain. Trans people in this camp often times put an emphasis on a clinical course for treatment. For example, a person goes to a psychologist, gets diagnosed with gender dysphoria, starts hormone replacement therapy, pursues surgery, then emerges from this process of either cured of the gender dysphoria or, at the very least, treated to the fullest extent of medical intervention. This position is more or less the original position held by trans activists, back in the day when the word "transsexual" was used instead of "transgender". Though many younger trans people, notably YouTuber Blaire White, also hold this position. Under this position, sex and gender are still quite intertwined, but a trans man can still be considered a man, and a trans woman a woman, under the belief that sex/gender doesn't just refer to chromosomal sex and reproductive organs, but also to neurobiology, genitalia, and secondary sex characteristics. So someone who is transgender, according to this view, is born with the physical characteristics of one sex/gender but the neurobiology of another, and will change their physical characteristics, to the fullest extent medically possible, to match the neurobiology and therefore cure the individual of gender dysphoria. Critics of this position argue that this mentality is problematic due to being inherently exclusive to transgender people who do not pursue medical transition, whom are often times deemed as "transtrenders" by people within this camp. Many people find it additionally problematic because it is also inherently exclusive to poorer trans people, particularly those in developing nations, who may not have access to trans-related medical care. Note that there are plenty of trans people who *do* have access to medical transition, but nevertheless feel as if the trans community shouldn't gatekeep people who cannot afford or do not desire medical transition, thus believing in the latter camp.
The "Gender Identity" camp
I feel like this camp is the one most popularly criticized by people on the right, but is also probably the most mainstream. It is the viewpoint held by many more left-wing trans people, (Note that in the aforementioned 2015 survey, only 1% of trans respondents voted Republican, so trans people are largely a pretty left-wing group, therefore it makes sense that this position would be the most mainstream) but also notably held by American Psychological Association, the American Psychiatric Association, GLAAD, and other mainstream health organizations and activist groups. While people in this camp still acknowledge that medical transition to treat gender dysphoria can still be a very important aspect of the transgender experience, it's believed that the *defining* experience is simply having a gender identity different from the one they were assigned at birth. "Gender identity" simply being the internal, personal sense of being a man, a woman, or outside the gender binary. Many people in this camp, though, still often maintain that gender identity is (at least partially) neurobiological, but differ from the first camp in regards to acknowledging that the issue is less black & white than an individual simply having a "male brain" or a "female brain", but rather that the neurological characteristics associated with gender exist on more of a spectrum, thus leaving the door open to gender non-conforming people who do not identify as trans, as well as to non-binary people. This is where the "gender is a spectrum" phrase comes from. "52 genders" is a popular right-wing meme that makes fun of this viewpoint, however it is important to note that many trans and non-binary people disagree with the idea of quantifying gender identity to such an absurd amount of individual genders, rather more simply maintaining that there are men, women, and a small portion of people in-between, with a few words such as "agender" or "genderqueer" being used to describe specific identities/presentations within this category. It's also noteworthy that not all people in this camp believe that neurobiology is the be-all-end-all of gender identity, as many believe that the performativity of gender also plays an integral role in one's identity. (That gender identity is a mixture of neurobiology and performativity is a position held by YouTuber Contrapoints) Trans people and biological sex So while the aforementioned "Gender Identity" viewpoint has become quite popularized among liberals and leftists, I have noticed a certain rhetorical mentality/assumption become prevalent alongside it, especially among cisgender people who consider themselves trans-allies: "Sex and Gender are different. A trans woman is a woman who is biologically male. A trans man is a man who is biologically female" When "Sex" is defined by someone's chromosomes, or the sex organs they were born with, this is correct. However, there is a pretty good reason why the trans community tends to prefer terms like "Assigned Male at Birth" rather than "Biologically Male". This is done not only for the inclusion of people who are both intersex and transgender (For example, someone can be born intersex but assigned male based on the existence of a penis or micropenis), but also due to the aforementioned viewpoint on divergent neurobiology being the cause for gender dysphoria. Those reasons are why the word "Assigned" is used. But the reason why it's "Assigned Male/Female At Birth" instead of just "Assigned Male/Female" is because among the trans community there exists an understanding of the mutability of sexually dimorphic biology that the general population is often ignorant to. For example, often times people (especially older folks) don't even know of the existence of Hormone Replacement Therapy, and simply assume that trans people get a single "sex change operation" that, (for a trans woman) would just entail the removal of the penis and getting breast implants. Therefore they imagine the process to be "medically sculpting a male to look female" instead of a more natural biological process of switching the endocrine system form male to female or vice versa and letting the body change over the course of multiple years. It doesn't help that, for a lot of older trans people (namely Caitlyn Jenner, who is probably the most high profile trans person sadly), the body can be a lot more resistant to change even with hormones so they *do* need to rely on plastic surgery a lot more to get obvious results) So what sexually dimorphic bodily characteristics can one expect to change from Hormone Replacement Therapy? (Note that there is a surprising lack of studies done on some of the more intricate changes that HRT can, so I've put a "*" next to the changes that are anecdotal, but still commonly and universally observed enough among trans people [including myself for the MTF stuff] to consider factual. I've also put a "✝" next to the changes that only occur when people transition before or during puberty) Male to Female:
Breast development and nipple/areolar enlargement, including in some people, the development of mammary glands and the ability to breastfeed
Thinning/slowed growth of facial/body hair
Cessation/reversal of male-pattern scalp hair loss
Softening of skin/decreased oiliness and acne
Decreased muscle mass/strength
Widening and rounding of the pelvis
Changes in mood, emotionality, and behavior (anecdotally crying is way easier to do)
Decreased sex drive (anecdotally, taking progesterone helps a lot in regards to regaining sex drive, though attraction is often noted as being experienced a bit differently than how it feels with testosterone)
Decreased sperm production/fertility
Decreased testicle size
Decreased penis size
Decreased prostate gland size
Voice changes (As far as I've heard, most people only experience minor changes from transitioning in adulthood, so it's common to do vocal training on top of everything to actually get a female-passing voice. I'll add a ✝ here since vocal changes seem to be a lot stronger in people who transition before/during puberty)
Changes in body odor (It's been documented that men and women often times have different smelling body odor, and trans people commonly notice a change in this regard) *
Changes in how arousal, sexual pleasure, and orgasms are experienced *
Changes in facial complexion *
Slight changes in hair color, texture, or curl *
Slight changes in eye color *
Changes in alcohol/drug tolerance *
Experiencing pubescent skeletal development and bodily growth along female-typical lines, including both bodily size/shape and facial bone/cartilage features ✝
Female to Male:
Growth of facial/body hair
male pattern scalp hair loss (in some individuals)
Roughening of the skin and prominence of veins
Increased muscle mass/strength
Changes in mood, emotionality, and behavior (I forget the source for this sadly but I remember reading that trans men are significantly more likely to commit crimes and get into fights after starting HRT)
Increased sex drive
Cessation of ovulation and menstruation
Acne (especially in the first few years of therapy)
Alterations in blood lipids (cholesterol and triglycerides)
Increased red blood cell count
Deepening of the voice
Enlargement of the clitoris
Changes in body odor *
Changes in how arousal, sexual pleasure, and orgasms are experienced *
Changes in facial complexion *
Slight changes in hair color, texture, or curl *
Slight changes in eye color *
Changes in alcohol/drug tolerance *
Experiencing male pubescent skeletal development and bodily growth along male-typical lines, and closure of growth plates ✝
Often times, when the whole "transgender people in sports" discussion arises, a logical error is made when *all* transgender people are assumed to be "biologically" their birth sex. For example, when talking about trans women participating in female sports, these instances will be referred to as cases of "Biological males competing against females". As mentioned before, calling a trans woman "biologically male" strictly in regards to chromosomes or sex organs at birth would be correct. However, not only can it be considered derogatory (the word "male" is colloquially a shorthand for "man", after all), but there are many instances where calling a post-HRT transgender person "biologically [sex assigned at birth]" is downright misleading. For example, hospitals have, given transgender patients improper or erroneous medical care by assuming treatment based on birth sex where treatment based on their current endocrinological sex would have been more adequate. Acute Clinical Care of Transgender Patients: A Review
Conclusions and relevance: Clinicians should learn how to engage with transgender patients, appreciate that unique anatomy or the use of gender-affirming hormones may affect the prevalence of certain disease (eg, cardiovascular disease, venous thromboembolism, and osteoporosis), and be prepared to manage specific issues, including those related to hormone therapy. Health care facilities should work toward providing inclusive systems of care that correctly identify and integrate information about transgender patients into the electronic health record, account for the unique needs of these patients within the facility, and through education and policy create a welcoming environment for their care.
Some hosptials have taken to labeling the biological sex of transgender patients as "MTF" (for post-HRT trans women) and "FTM" (for post-HRT trans men), which is a much more medically useful identifier compared to their sex assigned at birth. In regards to the sports discussion, I've seen *multiple threads* where redditors have backed up their opinions on the subject of trans people in sports with studies demonstrating that cis men are, on average, more athletically capable than cis women. Which I personally find to be a pathetic misunderstanding of the entire issue. Because we're not supposed to be comparing the athletic capabilities of natal males to natal females, here. We're supposed to comparing the athletic capabilities of *post-HRT male-to-females* to natal females. And, if we're going to really have a fact-based discussion on the matter, we need to have separate categories for pre-pubescent and post-pubescent transitioners. Since, as mentioned earlier, the former will likely have different skeletal characteristics compared to the latter. The currentInternational Olympic Committee(IOC) model for trans participation, and criticisms of said model (I quoted the specific guidelines from the International Cycling Union, but similar guidelines exist for all Olympic sports)
Elite Competition At elite competition levels, members may have the opportunity to represent the United States and participate in international competition. They may therefore be subject to the policies and regulations of the International Cycling Union (UCI) and International Olympic Committee (IOC). USA Cycling therefore follows the IOC guidelines on transgender athletes at these elite competition levels. For purposes of this policy, international competition means competition sanctioned by the UCI or competition taking place outside the United States in which USA Cycling’s competition rules do not apply. The IOC revised its guidelines on transgender athlete participation in 2015, to focus on hormone levels and medical monitoring. The main points of the guidelines are: Those who transition from female to male are eligible to compete in the male category without restriction. It is the responsibility of athletes to be aware of current WADA/USADA policies and file for appropriate therapeutic use exemptions. Those who transition from male to female are eligible to compete in the female category under the following conditions: The athlete has declared that her gender identity is female. The declaration cannot be changed, for sporting purposes, for a minimum of four years. The athlete must demonstrate that her total testosterone level in serum has been below 10 nmol/L for at least 12 months prior to her first competition (with the requirement for any longer period to be based on a confidential case-by-case evaluation, considering whether or not 12 months is a sufficient length of time to minimize any advantage in women’s competition). The athlete's total testosterone level in serum must remain below 10 nmol/L throughout the period of desired eligibility to compete in the female category. Compliance with these conditions may be monitored by random or for-cause testing. In the event of non-compliance, the athlete’s eligibility for female competition will be suspended for 12 months.
Valid criticisms of the IOC model are usually based on the fact that, even though hormone replacement therapy provokes changes to muscle mass, it does *not* shrink the size of someone's skeleton or cardiovascular system. Therefore an adult-transitioned trans woman could, even after losing all levels of male-typical muscle mass, still have an advantage in certain sports if she had an excessively large skeletal frame, and was participating in a sport where such a thing would be advantageous. Additionally, the guidelines only require that athletes be able to demonstrate having had female hormone levels for 12-24 months, which isn't necessarily long enough to completely lose musculature gained from training on testosterone (anecdotally it can take 2-4 years to completely lose male-typical muscle mass) So the IOC guidelines don't have any safeguard against, for example, a trans woman training with testosterone as the dominant hormone in her body, and then taking hormones for the bare minimum time period and still having some of the advantage left. Note that, while lower level sports have had (to the glee of right-wing publications sensationalizing the issue) instances of this exact thing happening, in the 16 years since these IOC guidelines were established, not a single transgender individual has won an Olympic medal Also note that none of the above criticisms of the IOC policy would apply in regards to the participation of pre-pubescent-transitioned trans women. After all, male-pubescent bone structure and cardiovascular size, and male-typical muscle levels, can't possibly exist if you never went through male puberty to begin with. What could better guidelines entail, to best preserve fairness in female sports while avoiding succumbing to anti-trans moral panic?
The most extreme way for female sports to reasonably go about addressing this issue would be to only allow for the participation of transgender women who are documented to have, with puberty blockers, carried out their transitions without having gone past Tanner Stage II or III of male puberty.
Sports leagues willing to be a bit looser could accept adult transitioners under the stipulation that their bodily measurements in regards to certain skeletal features fit within a standard deviation of the cis-female average
Sports leagues willing to be even looser could copy the IOC guidelines, but require documentation of having gone through HRT for a greater period of time rather than just the 12 months, (3 years would probably be better) to guarantee full loss of male muscle mass
In my personal opinion, sports leagues should pick one of the three above options depending on what best fits the nature of the sport and the eliteness of the competition. For example, extremely competitive contact sports might be better off going with the first option, but an aerobic sport such as marathon running would probably be fine with the third option.
How this issue has been misrepresented by The Right
Right-wing rhetoric surrounding this issue assumes that the issue exists as an innate consequence of trans activism (Ie. "This is what the left is pushing!") rather than as a result of individual sports leagues failing to have solid rules for participation. Often times, certain low-level sports leagues have failed to even measure trans athlete's hormone levels, and have, in some cases, let completely male-bodied athletes participate as women. This is obviously the fault of these specific sports leagues failing to implement or enforce reasonable rules for participation, but right-wing articles surrounding such instances will act as if these occurrences are an ideological goal of the pro-trans left. This runs off of the assumption that a majority of trans people and "the left" are specifically pushing for muscular males (who merely "identify" as women, and nothing more) to dominate female sports. When, in reality, we really had nothing to do with these occurrences, and the majority of trans people would even likely agree with the sentiments expressed in this post. Additionally, accepting the gender identities of trans people is something you can do irregardless of your opinion on the sports issue.
Over-exaggeration of the problem. The issue is often sensationalized to the extent of coming off as a call to action, to stop the trans activists and their SJW bullies from ruining female sports! They're coming after your daughter's lacrosse team! In reality, out of the hundreds of thousands (perhaps even more) of sports competitions that exist in the United States and throughout the world, an incredibly small percentage of them are actually ruined by trans participants. You hear the stories of the 6'5'' trans woman with the broad frame winning a weightlifting competition, but not of the hundreds of more average-sized trans-female athletes turning out more mediocre performances. This isn't to say that the niche cases don't present a problem that indeed needs to be fixed, but presenting the problem as more prevalent than it actually is acts as a rhetorical strategy meant to provoke anger as well as a more dramatic response. Buying into this rhetorical strategy, especially if you're is already somewhat ignorant to the issue to begin with, will make it much easier to convince you of accepting drastic solutions to the problems. Ie. "ONLY XX CHROMOSOMES ALLOWED IN FEMALE SPORTS", instead of any of the three more measured approaches suggested above. The provoked response of anger is also meant to turn people off of accepting trans rights in general.
Infuriatingly, I've noticed that right-wing rhetoric usually doesn't even mention pre-pubescent transitioners at all. Like, these people are fine with acknowledging the existence of puberty blockers when they're trying to make them illegal, but they refuse to talk about them in regards to the sports issue. There have been cases where conservative jurisdictions have banned the participation of all transgender students in girl's sports, period. Meaning a transgender girl who never went through male puberty at all, and has pre-pubescent hormone levels as a result of puberty blockers, could be banned from participating in girl's sports, while in reality said trans girl could possibly even be at a disadvantage compared to the cis girls, as a result of not even having started puberty yet. Nonsensical. And liberal allies are at fault of this too, I've noticed. I've seen countless reddit threads where left-leaning people voice their take on the trans sports issue without mentioning the existence of pre-pubescent transitioners. It's honestly ridiculous.
The sports issue is also used as an excuse to say derogatory things about trans women that would be less justifiable in other instances.
I'll use Joe Rogan as an example of this last thing:
She calls herself a woman but... I tend to disagree. And, uh, she, um... she used to be a man but now she has had, she's a transgender which is (the) official term that means you've gone through it, right? And she wants to be able to fight women in MMA. I say no f***ing way. I say if you had a dick at one point in time, you also have all the bone structure that comes with having a dick. You have bigger hands, you have bigger shoulder joints. You're a f***ing man. That's a man, OK? You can't have... that's... I don't care if you don't have a dick any more... If you want to be a woman in the bedroom and you know you want to play house and all of that other s*** and you feel like you have, your body is really a woman's body trapped inside a man's frame and so you got a operation, that's all good in the hood. But you can't fight chicks. Get the f*** out of here. You're out of your mind. You need to fight men, you know? Period. You need to fight men your size because you're a man. You're a man without a dick. I'm not trying to discriminate against women in any way, shape, or form and I'm a big supporter of women's fighting. I loved watching that Ronda Rousey/Liz Carmouche fight. But those are actual women. Those are actual women. And as strong as Ronda Rousey looks, she's still looks to me like a pretty girl. She's a beautiful girl who happens to be strong. She's a girl! [Fallon Fox] is not a girl, OK? This is a [transgender] woman. It's a totally different specification.
Calling a trans woman a "man", and equating transitioning to merely removal of the dick, and equating trans women's experiences as women as "playing house" and "being a woman in the bedroom". These things are obviously pretty transphobic, and if Rogan had said these things about just any random trans woman his statements would have likely been more widely seen in that light. But when it's someone having an unfair advantage in sports, and the audience is supposed to be angry with you, it's much more socially acceptable thing to say such things. But the problem is, when you say these kinds of things about one trans woman, you're essentially saying those derogatory things about all trans women by extension. It's the equivalent of using an article about a black home invader who murdered a family as an excuse to use a racial slur. Now, I'm not saying that Rogan necessarily did this on purpose, in fact I'm more inclined to believe that it was done moreso due to ignorance rather than having an actual ideological agenda. But since then, many right wing ideologues who do have an ideological agenda have used this issue as an excuse to voice their opinions on trans people while appearing to be less bigoted. Ie. "I'm not trying to be a bigot or anything and I accept people's rights to live their lives as they see fit, but we NEED to keep men out of women's sports", as a sly way to call trans women "men". Additionally, doing this allows them to slip in untrue statements about the biology of trans women. I mean, first of all in regards to the statement "You have bigger hands, you have bigger shoulder joints", obviously even in regards to post-pubescent transitioners, not every trans woman is going to have bigger hands and shoulder joints than every cis woman (My hands are actually smaller than my aunt's!). It's just that people who go through male puberty on average tend to have bigger hands and shoulder joints compared to people who go through female puberty. But over-exaggerating the breadth of sexual dimorphism, as if males and females are entirely different species to each-other, helps to paint the idea of transitioning in a more nonsensical light. I hope this thread has presented this issue in a better light for anyone reading it. Let me know if you have any thoughts/criticisms of my stances or the ways I went about this issue.

The present invention relates to a method for efficiently performing hierarchical design rules checks (DRC) and layout versus schematic comparison (LVS) on layout areas of an integrated circuit where cells overlap or where a cell and local geometry overlap. With the present invention, a hierarchical tree describes the integrated circuit’s layout data including cells having parent-child relationships and including local geometry. The present invention performs efficient layout verification by performing LVS and DRC checking on the new portions of an integrated circuit design and layout areas containing overlapping cells. When instances of cells overlap, the present invention determines the overlap area using predefined data structures that divide each cell into an array of spatial bins. Each bin of a parent is examined to determine if two or more cell instances reside therein or if a cell instance and local geometry reside therein. Once overlap is detected, the areas of the layout data corresponding to the overlap areas are selectively flattened prior to proceeding to DRC and LVS processing. During selective flattening of the overlap areas, the hierarchical tree is traversed from the top cell down through intermediate nodes to the leaf nodes. Each time geometry data is located during the traversal, it is pushes directly to the top cell without being stored in intermediate locations. This provides an effective mechanism for selective flattening.

Ambient audio signals from the customer shopping area within a store are sensed and fed to a signal processing circuit that produces a control signal which varies with variations in the amplitude of the sensed audio signals. A control circuit adjusts the amplitude of an auditory subliminal anti-shoplifting message to increase with increasing amplitudes of sensed audio signals and decrease with decreasing amplitudes of sensed audio signals. This amplitude controlled subliminal message may be mixed with background music and transmitted to the shopping area. To reduce distortion of the subliminal message, its amplitude is controlled to increase at a first rate slower than the rate of increase of the amplitude of ambient audio signals from the area. Also, the amplitude of the subliminal message is controlled to decrease at a second rate faster than the first rate with decreasing ambient audio signal amplitudes to minimize the possibility of the subliminal message becoming supraliminal upon rapid declines in ambient audio signal amplitudes in the area. A masking signal is provided with an amplitude which is also controlled in response to the amplitude of sensed ambient audio signals. This masking signal may be combined with the auditory subliminal message to provide a composite signal fed to, and controlled by, the control circuit.

Addressing Canada’s Employment Insurance Gap For Self-Employed Workers
Source: TD Ksenia Bushmeneva, Economist Dated July 15th, 2020
While the pandemic had devastated the overall labor market, workers in more precarious and non-standard work arrangements have been especially hard-hit.
Yet, many of these workers do not have access to employment insurance (EI) or run a higher risk than regular workers of not meeting qualification conditions. Only 64% of unemployed Canadians contributed to EI in 2018, meaning that millions would be left without financial assistance in the absence of the Canada Emergency Response Benefit (CERB).
Extending EI coverage to non-standard workers does have challenges. However, there is a growing understanding among many countries that these workers require social protection. More than two thirds of the OECD countries offer at least partial coverage for the self-employed. Their experience offers valuable lessons if Canada decides to follow suit.
The labor market recovery is likely to be uneven and protracted. This is especially true for self-employed and other non-standard workers, since their hours and incomes are more volatile and less protected. Having a more inclusive system with a broader contribution base, which accommodates non-standard workers but also includes a larger number of regular employees would help strengthen the recovery and build on economic gains achieved so far through the temporary CERB program.
The COVID-19 pandemic delivered a sudden and devastating blow to the Canadian labor market. Between February and April, millions of people lost their jobs as employment plunged by 16%. Unlike in previous recessions, the impact this time around has been disproportionately felt by workers in more precarious employment arrangements: part-time, temporary and self-employed, who are less likely to have access to unemployment insurance (EI). These types of work arrangement are more prevalent in the service sector industries, many of which have been hard-hit during this downturn. As of June, year-over-year (y/y) employment in part-time and temporary positions was down by 17% and 24%, respectively (Chart 1). For multiple job holders, employment fell by nearly 40%. By comparison, the 7% y/y decline in permanent positions seems relatively modest.
As dramatic as these declines are, they may still under-represent the pandemic’s toll on employment and incomes. Notably, overall hours worked fell more than employment during the months of lockdown and social distancing. This is especially true for non-standard workers who were more likely to work fewer hours than regular employees. For example, while self-employed workers saw only a 3% drop in employment since February, 43% of self-employed worked less than half of their usual hours in May (Chart 2). By comparison, among all employees, only 9% worked less than half of their usual hours. Moreover, self-employed people who were away from work were more hard-hit financially as they were far less likely to still be paid. Among incorporated self-employed workers with zero hours, less than 1 in 10 received pay compared to 1 in 4 for regular employees in the same situation.
As a result of the significant drop in hours worked, a far larger portion of the labor force was underutilized than suggested by the unemployment rate alone. While the official unemployment rate was 12.3% in June (equivalent to 2.45 million people), Statistics Canada noted that nearly 27% of the potential labour force was ‘underutilized’. The significant gap between the drop in the hours worked versus the more modest decline in employment helps to explain why 8.3 million of people have applied the Canada Emergency Response Benefit (CERB) (at any point during this crisis).
It is clear that self-employed and other non-standard workers were more impacted by the pandemic. Yet these workers usually have the least access to social safety nets, such as EI. Currently, EI unemployment benefits are mostly accessible to employees in the most traditional sense of the word: those that work full-time in a permanent positions for a single employer. By contrast, self-employed workers are not eligible for EIi, and, while those in temporary, contract and part-time positions are eligible, they might not have a chance to accumulate enough insurable hours to qualify because their work arrangements are less stable. Due to lack of EI coverage and significant loss of hours, nearly 40% of self-employed workers applied for CERB benefits, while only 12% and 5% of private and public employees did (Chart 3).
The reasons why some workers, such as those that are self-employed, are excluded are rooted in the design of the EI program. The program is based on insurance principles, with both employers and employees paying into it through mandatory contributions. The corollary is that those workers who have not paid in, as well as those who have left voluntarily without just cause, are disqualified. Contributions are also intended to make the program self-sufficient in the long-run as has been the case in Canada in recent years. In the case of self-employed workers, there’s also an issue of moral hazard when it comes to determining what represents a valid job separation (more on this in the section below: “What Complicates Offering EI Coverage For Non-Standard Workers”). For this and other reasons, many non-standard workers are currently ineligible for unemployment insurance.
These gaps in coverage have been growing as the job market has steadily tilted towards more non-standard work arrangements. In 2018, only 64% of unemployed Canadians had contributed to EI.ii Even among workers who have contributed, only 88% had accumulated enough insurable hours to qualify for benefits, which, depending on the regional level of unemployment, ranges between 420-700 hours in the 52-week period. The combined influence implies a relatively low EI coverage ratio for Canadian workers – out of 1.1 million Canadians who were unemployed in 2018, only 56% were eligible for EI.1 The share of unemployed workers who actually received EI benefits is even lower, averaging slightly above 40%.2 This is considerably below the median coverage among developed counties, which is around 60%.3
Due to data limitations and because non-standard workers include many different types of employment arrangements which may overlap, it is difficult to know with precision the prevalence of non-standard work in Canada. About 15% of Canadian workers are self-employed, while 17% work part-time. In 2016, Statistics Canada estimated that gig workers (self-employed freelancers, on-demand online workers and day labourers) accounted for roughly 8%-10% of Canadian workers. About half of those workers were relying exclusively on their gig income and had no other employment, making them ineligible for EI benefits.4
The low coverage rate and other limitations of the current EI system have been highlighted extensively in other research literature.5 For example, the fact that benefit eligibility and generosity varies geographically across Canada implies that there’s significant variability in coverage rates across provinces. EI coverage ratios are particularly low in Ontario, British Columbia and Alberta – all three provinces which also have above-national prevalence of self-employment (see Charts 4).6
In order to mitigate these shortcomings in the near term, the Canadian government rolled out the CERB program. Compared to EI, CERB qualification rules are very straightforward and were a quick means to provide financial assistance to an extremely broad and large number of applicants that included previously uninsured workers. CERB’s eligibility replaced the insurable hours threshold with a low and uniform income threshold, with anyone over the age of 15, having earned more than $5,000 in income in 2019 and who have lost their job or hours due to COVID-19. This had provided a helping hand to millions of non-standard workers in Canada. However, it has come with a steep price tag: in just three months since it was launched the government had already paid out $55 billions in benefits (as of July 5th) – nearly three times last year’s annual spending on EI and $28 billion more than it had predicted at the conception of the program.
CERB coverage was originally offered for 16 weeks, and was recently extended for an additional 8 weeks. However, it will start expiring in September for the earliest recipients, long before the labour market and certain industries are back to health. Unless adjustments are made to the EI program to accommodate non-standard workers, many of them may suddenly find themselves without unemployment assistance.
What Complicates Offering EI Coverage For Non-Standard Workers
Limited social protection for self-employed and other non-standard workers is not an issue unique to Canada. In most developed countries, non-standard workers have lower social protection compared to regular employees, with unemployment benefits being the least accessible benefit (Charts 5-8). Why is that and what makes implementation of unemployment insurance coverage for self-employed workers challenging for policymakers?
First of all, providing unemployment insurance for self-employed workers (and other non-standard workers) raises the issue of moral hazard. Put another way, presence of EI coverage may change behavior of self-employed workers making them less likely to take on work and more likely to remain unemployed. Non-standard workers tend to have more variable income, and they are far more likely to have lower future earnings than regular employees due, for example, to smaller assignments and contracts, or flexible pricing on various labor platforms (e.g. Uber). Lower expected future earnings could prompt them to quit in favor of EI benefits. More volatile earnings also make it more challenging to determine the appropriate income replacement rate. However, one solution to this could be to use income averaged over a period of time.
Secondly, for regular workers, reasons for leaving a job are transparent and can be verified with the employer. This is difficult to achieve in the case of non-standard workers. For example, if they avoid smaller assignments, then they will lose work but this will be impossible for government agencies to determine.
Some countries (e.g. Sweden, Austria, Slovakia, Spain) offer a voluntary option for self-employed workers to enroll into an employment insurance plan. However, a voluntary arrangement raises the issue of adverse selection. Workers with the highest risks or those that are most likely to make a claim have the greatest incentive to join, which limits the risk-sharing aspect of the program.
Adverse selection is something that Canada experienced first hand when it introduced the Special Benefits for Self-employed Workers (SBSE) in 2010 through the EI system, which allowed self employed workers to opt-in to gain access to maternity and parental benefits, sickness benefits and compassionate care and caregiver benefits. A 2016 program review study found that the characteristics, such as gender, age and income, of the self-employed workers who participated in the SBSE program were considerably different from the general sample of self-employed workers. In focus group studies, participants also indicated that the likelihood of making a claim was an important consideration for their decision to register for the benefits.7 Other issues with the voluntary scheme included a relatively low take-up rate, which in turn led to relatively high administration costs and required significant government subsidies to cover benefit payouts. Longer-run, low coverage is problematic for voluntary, contributions-financed, unemployment insurance schemes, as adverse selection could lead to a vicious cycle of rising insurance premiums and falling coverage. Meanwhile, achieving high coverage may require significant public subsidies because individual willingness to voluntarily pay for unemployment protection appears to be low.8 For those reasons, voluntary coverage schemes do not appear to work well in the case of non-standard workers.
Lastly, the current EI system is based on contributions from both employees and employers. In the case of the self-employed, it is not clear who will pick up the tab for the employer portion of the contribution. If the government subsidizes the employer portion, it could create adverse incentives for employers to hire a self-employed worker to reduce non-wage related labor costs. However, a lack of coverage for non-standard workers could also lead to this outcome, contributing to a rise in non-standard forms of employment. For example, in Italy, para-subordinate workers (self-employed but highly depended on one or very few clients) used to pay significantly lower pension contributions and were not eligible for unemployment and sickness benefits, resulting in significantly lower non-wage labor costs and a rising number of para-subordinated workers. In response to this Italy had gradually increased their contribution rates and expanded coverage. Levelling the playing field led to a significant decline in the prevalence of this type of employment. Austria had a similar experience with independent contractors.
Some Solutions Based on The International Experience
Despite the challenges in expanding unemployment insurance to non-standard workers, there is a growing understanding among many countries that the growing share of non-standard workers need social protection. As a result, more than two thirds of the OECD countries now offer at least partial unemployment benefits to self-employed workers. There’s a great variety of schemes, ranging from mandatory to partial and voluntary coverage, and no two are exactly alike. Still, their experience offers valuable lessons for Canada if it wishes to incorporate self-employed (and potentially other non-standard) workers into its EI system.
So what are some of the solutions of dealing with the higher moral hazard issue for non-standard workers? Lower level of EI benefits or a more restrictive access could be imposed in order to incentivize individuals to search for work or to keep their current job, and to offset higher level of moral hazard. In Sweden, for example, the moral hazard issue is mitigated through more restrictive access, allowing self-employed workers to claim benefits only after 5 years have passed since the previous claim. There is also a requirement that the firm has been shut down, which acts as an additional deterrent.
To mitigate adverse selection, upon starting a business, self-employed individuals in Austria have six months to decide whether they would like to participate in the voluntary unemployment insurance scheme, and that decision is binding for 8 years. In Canada, only half of startups survive to their eight-year anniversary, so there is a high likelihood EI could be used at least once by many self-employed business owners during this time period.10
Generally speaking, based on the OECD review,11 there appears to be a consensus that voluntary coverage schemes, particularly the ones with little or no commitment, such as Canada’s EI SBSE for the self-employed, are quite rare and do not work well to accommodate non-standard employment due to prevalent adverse selection, low participation and the significant public subsidies required to operate them.
On the other hand, mandatory EI contributions and coverage, like the one that currently exists for regular employees, would resolve the issue of adverse selection, hold more closely to the principle of risk sharing within their peer groups, and help to lower program costs. However, results from past surveys conducted in Canada found that there was little support among the self-employed for a mandatory contribution scheme.12 Due to the nature of their work, many self-employed workers indicated a preference to minimize their absence from work (to avoid the risk of losing clients etc.) suggesting that, unless their contribution rates are significantly lower, self-employed workers may get less “value-for-money” from EI programs, such as for example maternity/paternity leave, than traditional employees. The less predictable nature of their income means that they are likely more in need of an income protection program rather than employment insurance.
Indeed, based on surveys, their preferred financing option for temporary work/income disruptions was a tax-sheltered savings account.13 This is another viable alternative to contributions-funded EI, however, the downside is that individual contribution rates would need to be significantly higher in order to generate sufficient savings because there will be no splitting of contribution between employers and employees. There is also a risk that individuals, particularly those in part-time or low-income jobs, may not be able to accumulate sufficient savings to weather the unemployment or low-earnings spell.
For other non-standard workers, such as those with flexible hours or doing work for an online platform, one solution would be to introduce a wage premium for employees doing flexible work. This would compensate workers for the added income uncertainty. In Australia, for example, casual workers are entitled to a wage premium or have a minimum hours guarantee.
Lastly, if the goal is to make social protection more universal and harmonized across all forms of employment, a means-tested social protection system financed through general taxation, similar to that of Australia and New Zealand, could be adopted. However, moving to these systems would require a complete overhaul of Canada’s current contribution-based EI.
The labor market recovery is likely to be uneven and protracted. Even those workers that were able to return to work could remain underutilized and continue to face lower earnings due to social distancing restrictions and weaker consumer demand for a considerable period of time. This is especially true for self-employed and other non-standard workers, since their hours and incomes are more volatile and less protected. The rollout of CERB during the pandemic has been very helpful to address gaps in coverage within the current EI system. However, looking ahead, a more sustainable and permanent solution is required for workers outside the EI system. Having a more inclusive system with a broader contribution base, which accommodates non-standard workers but also includes a larger number of regular employees through more inclusive qualification criteria would help strengthen the recovery and maintain economic gains that were so far accomplished through CERB.
The traditional EI system is based on a binary choice of whether or not someone has a job. It is clear that with non-standard forms of employment becoming more prevalent, fewer people fit into that box. These workers need some form of insurance against joblessness as well as income volatility both during the current economic recovery and in the future to address the changing nature of employment relationships. Many OECD countries now offer various options for non-standard workers to participate in unemployment insurance systems, and their experience offers valuable lessons if Canada decides to follow suit.
Since 2010 self-employed workers can voluntarily participate in EI Special Benefit for Self-Employed Workers (SBSE) to gain access to many life event-type benefits accessible to regular employees, such as maternity and paternity leave programs, leave due to sickness or to care for an sick family member. In addition to this, current EI system allows certain exceptions for some non-standard workers. For example some individuals who work independently as barbers, hairdressers, taxi drivers, drivers of other passenger vehicles are eligible to receive benefits through the regular EI program. Fishermen are also included as insured persons under the EI Fishing Regulations. In the case of the self- employed fishermen, EI qualification is tied to income. In order to qualify for up to 26 weeks of benefit, they need to have earned between $2,500 to $4,200 in the last 31 weeks.
The two main reasons for not contributing to the EI program were not having worked in the previous 12 months, and non-insurable employment (which includes self-employment).
The following excerpt about microservice communication is from the new Microsoft eBook, Architecting Cloud-Native .NET Apps for Azure. The book is freely available for online reading and in a downloadable .PDF format at https://docs.microsoft.com/en-us/dotnet/architecture/cloud-native/ Microservice Guidance When constructing a cloud-native application, you'll want to be sensitive to how back-end services communicate with each other. Ideally, the less inter-service communication, the better. However, avoidance isn't always possible as back-end services often rely on one another to complete an operation. There are several widely accepted approaches to implementing cross-service communication. The type of communication interaction will often determine the best approach. Consider the following interaction types:
Query – when a calling microservice requires a response from a called microservice, such as, "Hey, give me the buyer information for a given customer Id."
Command – when the calling microservice needs another microservice to execute an action but doesn't require a response, such as, "Hey, just ship this order."
Event – when a microservice, called the publisher, raises an event that state has changed or an action has occurred. Other microservices, called subscribers, who are interested, can react to the event appropriately. The publisher and the subscribers aren't aware of each other.
Microservice systems typically use a combination of these interaction types when executing operations that require cross-service interaction. Let's take a close look at each and how you might implement them.
Many times, one microservice might need to query another, requiring an immediate response to complete an operation. A shopping basket microservice may need product information and a price to add an item to its basket. There are a number of approaches for implementing query operations.
One option for implementing this scenario is for the calling back-end microservice to make direct HTTP requests to the microservices it needs to query, shown in Figure 4-8. Figure 4-8. Direct HTTP communication While direct HTTP calls between microservices are relatively simple to implement, care should be taken to minimize this practice. To start, these calls are always synchronous and will block the operation until a result is returned or the request times outs. What were once self-contained, independent services, able to evolve independently and deploy frequently, now become coupled to each other. As coupling among microservices increase, their architectural benefits diminish. Executing an infrequent request that makes a single direct HTTP call to another microservice might be acceptable for some systems. However, high-volume calls that invoke direct HTTP calls to multiple microservices aren't advisable. They can increase latency and negatively impact the performance, scalability, and availability of your system. Even worse, a long series of direct HTTP communication can lead to deep and complex chains of synchronous microservices calls, shown in Figure 4-9: Figure 4-9. Chaining HTTP queries You can certainly imagine the risk in the design shown in the previous image. What happens if Step #3 fails? Or Step #8 fails? How do you recover? What if Step #6 is slow because the underlying service is busy? How do you continue? Even if all works correctly, think of the latency this call would incur, which is the sum of the latency of each step. The large degree of coupling in the previous image suggests the services weren't optimally modeled. It would behoove the team to revisit their design.
Materialized View pattern
A popular option for removing microservice coupling is the Materialized View pattern. With this pattern, a microservice stores its own local, denormalized copy of data that's owned by other services. Instead of the Shopping Basket microservice querying the Product Catalog and Pricing microservices, it maintains its own local copy of that data. This pattern eliminates unnecessary coupling and improves reliability and response time. The entire operation executes inside a single process. We explore this pattern and other data concerns in Chapter 5.
Service Aggregator Pattern
Another option for eliminating microservice-to-microservice coupling is an Aggregator microservice, shown in purple in Figure 4-10. Figure 4-10. Aggregator microservice The pattern isolates an operation that makes calls to multiple back-end microservices, centralizing its logic into a specialized microservice. The purple checkout aggregator microservice in the previous figure orchestrates the workflow for the Checkout operation. It includes calls to several back-end microservices in a sequenced order. Data from the workflow is aggregated and returned to the caller. While it still implements direct HTTP calls, the aggregator microservice reduces direct dependencies among back-end microservices.
Another approach for decoupling synchronous HTTP messages is a Request-Reply Pattern, which uses queuing communication. Communication using a queue is always a one-way channel, with a producer sending the message and consumer receiving it. With this pattern, both a request queue and response queue are implemented, shown in Figure 4-11. Figure 4-11. Request-reply pattern Here, the message producer creates a query-based message that contains a unique correlation ID and places it into a request queue. The consuming service dequeues the messages, processes it and places the response into the response queue with the same correlation ID. The producer service dequeues the message, matches it with the correlation ID and continues processing. We cover queues in detail in the next section.
Another type of communication interaction is a command. A microservice may need another microservice to perform an action. The Ordering microservice may need the Shipping microservice to create a shipment for an approved order. In Figure 4-12, one microservice, called a Producer, sends a message to another microservice, the Consumer, commanding it to do something. Figure 4-12. Command interaction with a queue Most often, the Producer doesn't require a response and can fire-and-forget the message. If a reply is needed, the Consumer sends a separate message back to Producer on another channel. A command message is best sent asynchronously with a message queue. supported by a lightweight message broker. In the previous diagram, note how a queue separates and decouples both services. A message queue is an intermediary construct through which a producer and consumer pass a message. Queues implement an asynchronous, point-to-point messaging pattern. The Producer knows where a command needs to be sent and routes appropriately. The queue guarantees that a message is processed by exactly one of the consumer instances that are reading from the channel. In this scenario, either the producer or consumer service can scale out without affecting the other. As well, technologies can be disparate on each side, meaning that we might have a Java microservice calling a Golang microservice. In chapter 1, we talked about backing services. Backing services are ancillary resources upon which cloud-native systems depend. Message queues are backing services. The Azure cloud supports two types of message queues that your cloud-native systems can consume to implement command messaging: Azure Storage Queues and Azure Service Bus Queues.
Azure Storage Queues
Azure storage queues offer a simple queueing infrastructure that is fast, affordable, and backed by Azure storage accounts. Azure Storage Queues feature a REST-based queuing mechanism with reliable and persistent messaging. They provide a minimal feature set, but are inexpensive and store millions of messages. Their capacity ranges up to 500 TB. A single message can be up to 64 KB in size. You can access messages from anywhere in the world via authenticated calls using HTTP or HTTPS. Storage queues can scale out to large numbers of concurrent clients to handle traffic spikes. That said, there are limitations with the service:
Message order isn't guaranteed.
A message can only persist for seven days before it's automatically removed.
Support for state management, duplicate detection, or transactions isn't available.
Azure Service Bus Queues
For more complex messaging requirements, consider Azure Service Bus queues. Sitting atop a robust message infrastructure, Azure Service Bus supports a brokered messaging model. Messages are reliably stored in a broker (the queue) until received by the consumer. The queue guarantees First-In/First-Out (FIFO) message delivery, respecting the order in which messages were added to the queue. The size of a message can be much larger, up to 256 KB. Messages are persisted in the queue for an unlimited period of time. Service Bus supports not only HTTP-based calls, but also provides full support for the AMQP protocol. AMQP is an open-standard across vendors that supports a binary protocol and higher degrees of reliability. Service Bus provides a rich set of features, including transaction support and a duplicate detection feature. The queue guarantees "at most once delivery" per message. It automatically discards a message that has already been sent. If a producer is in doubt, it can resend the same message, and Service Bus guarantees that only one copy will be processed. Duplicate detection frees you from having to build additional infrastructure plumbing. Two more enterprise features are partitioning and sessions. A conventional Service Bus queue is handled by a single message broker and stored in a single message store. But, Service Bus Partitioning spreads the queue across multiple message brokers and message stores. The overall throughput is no longer limited by the performance of a single message broker or messaging store. A temporary outage of a messaging store doesn't render a partitioned queue unavailable. Service Bus Sessions provide a way to group-related messages. Imagine a workflow scenario where messages must be processed together and the operation completed at the end. To take advantage, sessions must be explicitly enabled for the queue and each related messaged must contain the same session ID. However, there are some important caveats: Service Bus queues size is limited to 80 GB, which is much smaller than what's available from store queues. Additionally, Service Bus queues incur a base cost and charge per operation. Figure 4-14 outlines the high-level architecture of a Service Bus queue. Figure 4-14. Service Bus queue In the previous figure, note the point-to-point relationship. Two instances of the same provider are enqueuing messages into a single Service Bus queue. Each message is consumed by only one of three consumer instances on the right. Next, we discuss how to implement messaging where different consumers may all be interested the same message.
Message queuing is an effective way to implement communication where a producer can asynchronously send a consumer a message. However, what happens when many different consumers are interested in the same message? A dedicated message queue for each consumer wouldn't scale well and would become difficult to manage. To address this scenario, we move to the third type of message interaction, the event. One microservice announces that an action had occurred. Other microservices, if interested, react to the action, or event. Eventing is a two-step process. For a given state change, a microservice publishes an event to a message broker, making it available to any other interested microservice. The interested microservice is notified by subscribing to the event in the message broker. You use the Publish/Subscribe pattern to implement event-based communication. Figure 4-15 shows a shopping basket microservice publishing an event with two other microservices subscribing to it. Figure 4-15. Event-Driven messaging Note the event bus component that sits in the middle of the communication channel. It's a custom class that encapsulates the message broker and decouples it from the underlying application. The ordering and inventory microservices independently operate the event with no knowledge of each other, nor the shopping basket microservice. When the registered event is published to the event bus, they act upon it. With eventing, we move from queuing technology to topics. A topic is similar to a queue, but supports a one-to-many messaging pattern. One microservice publishes a message. Multiple subscribing microservices can choose to receive and act upon that message. Figure 4-16 shows a topic architecture. Figure 4-16. Topic architecture In the previous figure, publishers send messages to the topic. At the end, subscribers receive messages from subscriptions. In the middle, the topic forwards messages to subscriptions based on a set of rules, shown in dark blue boxes. Rules act as a filter that forward specific messages to a subscription. Here, a "GetPrice" event would be sent to the price and logging Subscriptions as the logging subscription has chosen to receive all messages. A "GetInformation" event would be sent to the information and logging subscriptions. The Azure cloud supports two different topic services: Azure Service Bus Topics and Azure EventGrid.
Azure Service Bus Topics
Sitting on top of the same robust brokered message model of Azure Service Bus queues are Azure Service Bus Topics. A topic can receive messages from multiple independent publishers and send messages to up to 2,000 subscribers. Subscriptions can be dynamically added or removed at runtime without stopping the system or recreating the topic. Many advanced features from Azure Service Bus queues are also available for topics, including Duplicate Detection and Transaction support. By default, Service Bus topics are handled by a single message broker and stored in a single message store. But, Service Bus Partitioning scales a topic by spreading it across many message brokers and message stores. Scheduled Message Delivery tags a message with a specific time for processing. The message won't appear in the topic before that time. Message Deferral enables you to defer a retrieval of a message to a later time. Both are commonly used in workflow processing scenarios where operations are processed in a particular order. You can postpone processing of received messages until prior work has been completed. Service Bus topics are a robust and proven technology for enabling publish/subscribe communication in your cloud-native systems.
Azure Event Grid
While Azure Service Bus is a battle-tested messaging broker with a full set of enterprise features, Azure Event Grid is the new kid on the block. At first glance, Event Grid may look like just another topic-based messaging system. However, it's different in many ways. Focused on event-driven workloads, it enables real-time event processing, deep Azure integration, and an open-platform - all on serverless infrastructure. It's designed for contemporary cloud-native and serverless applications As a centralized eventing backplane, or pipe, Event Grid reacts to events inside Azure resources and from your own services. Event notifications are published to an Event Grid Topic, which, in turn, routes each event to a subscription. Subscribers map to subscriptions and consume the events. Like Service Bus, Event Grid supports a filtered subscriber model where a subscription sets rule for the events it wishes to receive. Event Grid provides fast throughput with a guarantee of 10 million events per second enabling near real-time delivery - far more than what Azure Service Bus can generate. A sweet spot for Event Grid is its deep integration into the fabric of Azure infrastructure. An Azure resource, such as Cosmos DB, can publish built-in events directly to other interested Azure resources - without the need for custom code. Event Grid can publish events from an Azure Subscription, Resource Group, or Service, giving developers fine-grained control over the lifecycle of cloud resources. However, Event Grid isn't limited to Azure. It's an open platform that can consume custom HTTP events published from applications or third-party services and route events to external subscribers. When publishing and subscribing to native events from Azure resources, no coding is required. With simple configuration, you can integrate events from one Azure resource to another leveraging built-in plumbing for Topics and Subscriptions. Figure 4-17 shows the anatomy of Event Grid. Figure 4-17. Event Grid anatomy A major difference between EventGrid and Service Bus is the underlying message exchange pattern. Service Bus implements an older style pull model in which the downstream subscriber actively polls the topic subscription for new messages. On the upside, this approach gives the subscriber full control of the pace at which it processes messages. It controls when and how many messages to process at any given time. Unread messages remain in the subscription until processed. A significant shortcoming is the latency between the time the event is generated and the polling operation that pulls that message to the subscriber for processing. Also, the overhead of constant polling for the next event consumes resources and money. EventGrid, however, is different. It implements a push model in which events are sent to the EventHandlers as received, giving near real-time event delivery. It also reduces cost as the service is triggered only when it's needed to consume an event – not continually as with polling. That said, an event handler must handle the incoming load and provide throttling mechanisms to protect itself from becoming overwhelmed. Many Azure services that consume these events, such as Azure Functions and Logic Apps provide automatic autoscaling capabilities to handle increased loads. Event Grid is a fully managed serverless cloud service. It dynamically scales based on your traffic and charges you only for your actual usage, not pre-purchased capacity. The first 100,000 operations per month are free – operations being defined as event ingress (incoming event notifications), subscription delivery attempts, management calls, and filtering by subject. With 99.99% availability, EventGrid guarantees the delivery of an event within a 24-hour period, with built-in retry functionality for unsuccessful delivery. Undelivered messages can be moved to a "dead-letter" queue for resolution. Unlike Azure Service Bus, Event Grid is tuned for fast performance and doesn't support features like ordered messaging, transactions, and sessions.
Streaming messages in the Azure cloud
Azure Service Bus and Event Grid provide great support for applications that expose single, discrete events like a new document has been inserted into a Cosmos DB. But, what if your cloud-native system needs to process a stream of related events? Event streams are more complex. They're typically time-ordered, interrelated, and must be processed as a group. Azure Event Hub is a data streaming platform and event ingestion service that collects, transforms, and stores events. It's fine-tuned to capture streaming data, such as continuous event notifications emitted from a telemetry context. The service is highly scalable and can store and process millions of events per second. Shown in Figure 4-18, it's often a front door for an event pipeline, decoupling ingest stream from event consumption. Figure 4-18. Azure Event Hub Event Hub supports low latency and configurable time retention. Unlike queues and topics, Event Hubs keep event data after it's been read by a consumer. This feature enables other data analytic services, both internal and external, to replay the data for further analysis. Events stored in event hub are only deleted upon expiration of the retention period, which is one day by default, but configurable. Event Hub supports common event publishing protocols including HTTPS and AMQP. It also supports Kafka 1.0. Existing Kafka applications can communicate with Event Hub using the Kafka protocol providing an alternative to managing large Kafka clusters. Many open-source cloud-native systems embrace Kafka. Event Hubs implements message streaming through a partitioned consumer model in which each consumer only reads a specific subset, or partition, of the message stream. This pattern enables tremendous horizontal scale for event processing and provides other stream-focused features that are unavailable in queues and topics. A partition is an ordered sequence of events that is held in an event hub. As newer events arrive, they're added to the end of this sequence. Figure 4-19 shows partitioning in an Event Hub. Figure 4-19. Event Hub partitioning Instead of reading from the same resource, each consumer group reads across a subset, or partition, of the message stream. For cloud-native applications that must stream large numbers of events, Azure Event Hub can be a robust and affordable solution.

[Table] Asteroid Day AMA – We’re engineers and scientists working on a mission that could, one day, help save humankind from asteroid extinction. Ask us anything!
Source There are several people answering: Paolo Martino is PM, Marco Micheli is MM, Heli Greus is HG, Detlef Koschny is DVK, and Aidan Cowley is AC.
Can we really detect any asteroids in space with accuracy and do we have any real means of destroying it?
Yes, we can detect new asteroids when they are still in space. Every night dozens of new asteroids are found, including a few that can come close to the Earth.
Regarding the second part of the question, the goal would be to deflect them more than destroy them, and it is technologically possible. The Hera/DART mission currently being developed by ESA and NASA will demonstrate exactly this capability.
I always wanted to ask: what is worse for life on Earth - to be hit by a single coalesced asteroid chunk, or to be hit by a multiple smaller pieces of exploded asteroid, aka disrupted rubble pile scenario?
DVK: This is difficult to answer. If the rubble is small (centimetres to meters) it is better to have lots of small ones – they’d create nice bright meteors. If the rubble pieces are tens of meters it doesn’t help.
Let’s say that hypothetically, an asteroid the size of Rhode Island is coming at us, it will be a direct hit - you’ve had the resources and funding you need, your plan is fully in place, everything you’ve wanted you got. The asteroid will hit in 10 years, what do you do?
DVK: I had to look up how big Rhode Island is – a bit larger than the German Bundesland ‘Saarland’. Ok – this would correspond to an object about 60 km in diameter, right? That’s quite big – we would need a lot of rocket launches, this would be extremely difficult. I would pray. The good news is that we are quite convinced that we know all objects larger than just a few kilometers which come close to our planet. None of them is on a collision course, so we are safe.
the below is a reply to the above
Why are you quite convinced that you know all object of that size? And what is your approach in finding new celestial bodies?
DVK: There was a scientific study done over a few years (published in Icarus 2018, search for Granvik) where they modelled how many objects there are out there. They compared this to the observations we have with the telescopic surveys. This gives us the expected numbers shown here on our infographic: https://www.esa.int/ESA_Multimedia/Images/2018/06/Asteroid_danger_explained
There are additional studies to estimate the ‘completeness’ – and we think that we know everything above roughly a few km in size.
Thanks for the answer, that's really interesting! It's also funny that the fist Flyeye deployed is in Sicily, at less than 100km from me, I really had no idea
DVK: Indeed, that's cool. Maybe you can go and visit it one day.
the below is a reply to the original answer
What about Interstellar objects however, like Oumuamua?
DVK: The two that we have seen - 'Oumuamua and comet Borisov - were much smaller than the Saarland (or Rhode Island ;-) - not sure about Borisov, but 'Oumuamua was a few hundred meters in size. So while they could indeed come as a complete surprise, they are so rare that I wouldn't worry.
Would the public be informed if an impending asteroid event were to happen? And, how would the extinction play out? Bunch of people crushed to death, knocked off our orbit, dust clouds forever?
DVK: We do not keep things secret – all our info is at the web page http://neo.ssa.esa.int. The ‘risky’ objects are in the ‘risk page’. We also put info on really close approaches there. It would also be very difficult to keep things ‘under cover’ – there are many high-quality amateur astronomers out there that would notice.
In 2029 asteroid Apophis will fly really close to Earth, even closer than geostationary satellites. Can we use some of those satellites to observe the asteroid? Is it possible to launch very cheap cube sats to flyby Apophis in 2029?
DVK: Yes an Apophis mission during the flyby in 2029 would be really nice. We even had a special session on that topic at the last Planetary Defense Conference in 2019, and indeed CubeSats were mentioned. This would be a nice university project – get me a close-up of the asteroid with the Earth in the background!
Go to the section 'resolutions'. This is now a statement that scientists can use to present to their funding agencies, demonstrating that it's not just their own idea.
Thanks for doing this AMA! Did we know the Chelyabinsk meteor in 2013 (the one which had some great videos on social media) was coming? Ig not, how comes? Also, as a little side one, have there been any fatalities from impact events in the past 20 years?
Unfortunately, the Chelyabinsk object was not seen in advance, because it came from the direction of the Sun where ground-based telescopes cannot look.
No known fatalities from impacts have happened in the past 20 years, although the Chelyabinsk event did cause many injuries, fortunately mostly minor.
the below is a reply to the above
How often do impacts from that direction happen, compared to impacts from visible trajectories?
In terms of fraction of the sky, the area that cannot be easily scanned from the ground is roughly a circle with a radius of 40°-50° around the current position of the Sun, corresponding to ~15% of the total sky. However, there is a slight enhancement of objects coming from that direction, therefore the fraction of objects that may be missed when heading towards us is a bit higher.
However, this applies only when detecting an asteroid in its "final plunge" towards the Earth. Larger asteroids can be spotted many orbits earlier, when they are farther away and visible in the night side of the sky. Their orbits can then be determined and their possible impacts predicted even years or decades in advance.
There must be a trade-off when targeting asteroids as they get closer to Earth, is there a rule of thumb at what the best time is to reach them, in terms of launch time versus time to reach the asteroid and then distance from Earth?
DVK: Take e.g. a ‘kinetic impactor’ mission, like what DART and Hera are testing. Since we only change the velocity of the asteroid slightly, we need to hit the object early enough so that the object has time to move away from it’s collision course. Finding out when it is possible to launch requires simulations done by our mission analysis team. They take the strength of the launcher into account, also the available fuel for course corrections, and other things. Normally each asteroid has its own best scenario.
Do you also look at protecting the moon from asteroids? Would an impact of a large enough scale potentially have major impacts on the earth?
DVK: There are programmes that monitor the Moon and look for flashes from impacting small asteroids (or meteoroids) - https://neliota.astro.noa.g or the Spanish MIDAS project. We use the data to improve our knowledge about these objects. These programmes just look at what is happening now.
For now we would not do anything if we predicted a lunar impact. I guess this will change once we have a lunar base in place.
Why aren't there an international organisation comprised of countries focused on the asteroid defence? Imagine like the organisation with multi-billion $ budget and program of action on funding new telescopes, asteroid exploration mission, plans for detection of potentially dangerous NEA, protocols on action after the detection - all international, with heads of states discussing these problems?
DVK: There are international entities in place, mandated by the UN: The International Asteroid Warning Network (http://www.iawn.net) and the Space Mission Planning Advisory Group (http://www.smpag.net). These groups advise the United Nations. That is exactly where we come up with plans and protocols on action. But: They don’t have budget – that needs to come from elsewhere. I am expecting that if we have a real threat, we would get the budget. Right now, we don’t have a multi-billion budget.
the below is a reply to someone else's answer
There is no actual risk of any sizable asteroids hitting earth in the foreseeable future. Any preparation for it would just be a waste of money.
DVK: Indeed, as mentioned earlier, we do not expect a large object to hit is in the near future. We are mainly worried about those in the size range of 20 m to 40 m, which happen on average every few tens of years to hundreds of years. And where we only know a percent of them or even less.
President Obama wanted to send a crewed spacecraft to an asteroid - in your opinion is this something that should still be done in the future, would there be any usefulness in having a human being walk/float on an asteroid's surface?
DVK: It would definitely be cool. I would maybe even volunteer to go. Our current missions to asteroids are all robotic, the main reason is that it is much cheaper (but still expensive) to get the same science. But humans will expand further into space, I am sure. If we want to test human exploration activities, doing this at an asteroid would be easier than landing on a planet.
this is another reply
Yes, but I am slightly biased by the fact that I work at the European astronaut centre ;) There exist many similarities to what we currently do for EVA (extra vehicular activities) operations on the International Space Station versus how we would 'float' around an asteroid. Slightly biased again, but using such a mission to test exploration technologies would definitely still have value. Thanks Obama! - AC
I've heard that some asteroids contains large amounts of iron. Is there a possibility that we might have "space mines" in the far away future, if our own supply if iron runs out?
Yes, this is a topic in the field known as space mining, part of what we call Space Resources. In fact, learning how we can process material we might find on asteroids or other planetary bodies is increasingly important, as it opens up the opportunities for sustainable exploration and commercialization. Its a technology we need to master, and asteroids can be a great target for testing how we can create space mines :) - AC
By how much is DART expected to deflect Didymos? Do we have any indication of the largest size of an asteroid we could potentially deflect?
PM: Didymos is a binary asteroid, consisting of a main asteroid Didymos A (~700m) and a smaller asteroid Didymos B (~150m) orbiting around A with a ~12 hours period. DART is expected to impact Didymos B and change its orbital period w.r.t. Didymos A of ~1%. (8 mins)
The size of Didymos B is the most representative of a potential threat to Earth (the highest combination of probability and consequence of impacts), meaning smaller asteroids hit the Earth more often but have less severe consequences, larger asteroids can have catastrophic consequences but their probability of hitting the earth is very very low.
the below is a reply to the above
Why is there less probability of larger asteroids hitting earth?
DVK: There are less large objects out there. The smaller they are, the more there are.
the below is a reply to the original answer
Is there any chance that your experiment will backfire and send the asteroid towards earth?
PM: Not at all, or we would not do that :) Actually Dimorphos (the Didymos "moon") will not even leave its orbit around Didymos. It will just slightly change its speed.
I'm sure you've been asked this many times but how realistic is the plot of Armageddon? How likely is it that our fate as a species will rely on (either) Bruce Willis / deep sea oil drillers?
Taking into consideration that Bruce Willis is now 65 and by the time HERA is launched he will be 69, I do not think that we can rely on him this time (although I liked the movie).
HERA will investigate what method we could use to deflect asteroid and maybe the results will show that we indeed need to call the deep sea oil drillers.
the below is a reply to the above
So then would it be easier to train oil drillers to become astronauts, or to train astronauts to be oil drillers?
I do not know which one would be easier since I have no training/experience of deep see oil drilling nor becoming an astronaut, but as long as the ones that would go to asteroid have the sufficient skills and training (even Bruce Willis), I would be happy.
If budget was no object, which asteroid would you most like to send a mission to?
Nice question! For me, I'd be looking at an asteroid we know something about, since I would be interested in using it for testing how we could extract resources from it. So for me, I would choose Itokawa (https://en.wikipedia.org/wiki/25143_Itokawa), which was visited by Hayabusa spacecraft. So we already have some solid prospecting carried out for this 'roid! - AC
this is another reply
Not sure if it counts as an asteroid, but Detlef and myself would probably choose ʻOumuamua, the first discovered interstellar object.
the below is a reply to the above
Do we even have the capability to catch up to something like that screaming through our solar system? That thing has to have a heck of a velocity to just barrel almost straight through like that.
DVK: Correct, that would be a real challenge. We are preparing for a mission called 'Comet Interceptor' that is meant to fly to an interstellar object or at least a fresh comet - but it will not catch up with it, it will only perform a short flyby.
After proving to be able to land on one, could an asteroid serve as a viable means to transport goods and or humans throughout the solar system when the orbit of said asteroid proves beneficial. While it is probably quite problematic to land the payload, it could save fuel or am I mistaken?
Neat idea! Wonder if anyone has done the maths on the amount of fuel you would need/save vs certain targets. - AC
PM: To further complement, the saving is quite marginal indeed because in order to land (softly) on the asteroid you actually need to get into the very same orbit of that asteroid . At that point your orbit remains the same whether you are on the asteroid or not..
can the current anti-ballistic missiles systems intercept a terminal phase earth strike asteroid? or it is better to know beforehand and launch an impacting vehicle into space?
DVK: While I do see presentations on nuclear explosions to deflect asteroids at our professional meetings, I have not seen anybody yet studying how we could use existing missile systems. So it's hard to judge whether existing missiles would do the job. But in general, it is better to know as early as possible about a possible impact and deflect it as early as possible. This will minimize the needed effort.
How much are we prepared against asteroid impacts at this moment?
DVK: 42… :-) Seriously – I am not sure how to quantify ‘preparedness’. We have international working groups in place, mentioned earlier (search for IAWN, SMPAG). We have a Planetary Defence Office at ESA, a Planetary Defense Office at NASA (who spots the difference?), search the sky for asteroids, build space missions… Still we could be doing more. More telescopes to find the object, a space-based telescope to discover those that come from the direction of the Sun. Different test missions would be useful, … So there is always more we could do.
Have you got any data on the NEO coverage? Is there estimations on the percentage of NEOs we have detected and are tracking? How can we improve the coverage? How many times have asteroids been able to enter earths atmosphere without being detected beforehand?
As expected, we are now nearly complete for the large ones, while many of the smaller ones are still unknown.
In order to improve coverage, we need both to continue the current approach, centered on ground-based telescopes, and probably also launch dedicated telescopes to space, to look at the fraction of the sky that cannot be easily observed from the ground (e.g., towards the Sun).
Regarding the last part of your question, small asteroids enter the Earth atmosphere very often (the infographics above gives you some numbers), while larger ones are much rarer.
In the recent past, the largest one to enter our atmosphere was about 20 meters in diameter, and it caused the Chelyabinsk event in 2013. It could not be detected in advance because it came from the direction of the Sun.
We have however detected a few small ones before impact. The first happened in 2008, when a ~4-meter asteroid was found to be on a collision course less than a day before impact, it was predicted to fall in Northern Sudan, and then actually observed falling precisely where (and when) expected.
this is another reply
DVK: And to add what MM said - Check out http://neo.ssa.esa.int. There is a ‘discovery statistics’ section which provides some of the info you asked about. NASA is providing similar information here https://cneos.jpl.nasa.gov/stats/. To see the sky which is currently covered by the survey telescopes, you need to service of the Minor Planet Center which we all work together with: http://www.minorplanetcenter.org, ‘observers’, ‘sky coverage’. That is a tool we use to plan where we look with our telescopes, so it is a more technical page.
Are there any automatic systems for checking large numbers of asteroids orbits, to see if the asteroid's orbit is coming dangerously close to Earth, or is it done by people individually for every asteroid? I ask it because LSST Rubin is coming online soon and you know it will discover a lot of new asteroids.
Yes, such systems exist, and monitor all known and newly discovered asteroids in order to predict possible future impacts.
It is automatically updated every day once new observational data is processed.
What are your favourite sci-fi series?
DVK: My favorites are ‘The Expanse’, I also liked watching ‘Salvation’. For the first one I even got my family to give me a new subscription to a known internet streaming service so that I can see the latest episodes. I also loved ‘The Jetsons’ and ‘The Flintstones’ as a kid. Not sure the last one counts as sci-fi though. My long-time favorite was ‘Dark Star’.
this is another reply
Big fan of The Expanse at the moment. Nice, hard sci-fi that has a good impression of being grounded in reality - AC
this is another reply
When I was a kid I liked The Jetsons, when growing up Star Trek, Star wars and I also used to watch with my sister the 'V'.
When determining the potential threat of a NEA, is the mass of an object a bigger factor or size? I'm asking because I'm curious if a small but massive object (say, with the density of Psyche) could survive atmospheric entry better than a comparatively larger but less massive object.
The mass is indeed what really matters, since it’s directly related with the impact energy.
And as you said composition also matters, a metal object would survive atmospheric entry better, not just because it’s heavier, but also because of its internal strength.
What are your thoughts on asteroid mining as portrayed in sci-fi movies? Is it feasible? If so would governments or private space programs be the first to do so?What type of minerals can be found on asteroids that would merit the costs of extraction?
Certainly there is valuable stuff you can find on asteroids. For example, the likely easiest material you can harvest from an asteroid would be volatiles such as H2O. Then you have industrial metals, things like Iron, Nickel, and Platinum group metals. Going further, you can break apart many of the oxide minerals you would find to get oxygen (getting you closer to producing rocket fuel in-situ!). Its feasible, but still needs alot of testing both here on Earth and eventually needs to be tested on a target. It may be that governments, via agencies like ESA or NASA, may do it first, to prove the principles somewhat, but I know many commercial entities are also aggresively working towards space mining. To show you that its definitely possible, I'd like to plug the work of colleagues who have processed lunar regolith (which is similar to what you may find on asteroids) to extract both oxygen and metals. Check it out here: http://www.esa.int/ESA_Multimedia/Images/2019/10/Oxygen_and_metal_from_lunar_regolith
Will 2020's climax be a really big rock?
DVK: Let's hope not...
Considering NASA, ESA, IAU etc. is working hard to track Earth-grazing asteroids, how come the Chelyabinsk object that airburst over Russia in 2013 came as a total surprise?
The Chelyabinsk object came from the direction of the Sun, where unfortunately ground-based telescopes cannot look at. Therefore, it would not have been possible to discover it in advance with current telescopes. Dedicated space telescopes are needed to detect objects coming from this direction in advance.
the below is a reply to the above
Is this to say that it was within specific solid angles for the entire time that we could have observed it given its size and speed?
Yes, precisely that. We got unlucky in this case.
Have any of you read Lucifer's Hammer by Larry Niven? In your opinion, how realistic is his depiction of an asteroid strike on Earth?
DVK: I have – but really long ago, so I don’t remember the details. But I do remember that I really liked the book, and I remember I always wanted to have a Hot Fudge Sundae when reading it.
I was thinking about the asteroid threat as a teen and came up with this ideas (Hint: they are not equally serious, the level of craziness goes up real quick). Could you please comment on their feasibility? 1. Attaching a rocket engine to an asteroid to make it gradually change trajectory, do that long in advance and it will miss Earth by thousands of km 2. Transporting acid onto asteroid (which are mainly metal), attaching a dome-shaped reaction chamber to it, using heat and pressure to then carry out the chemical reaction to disintegrate asteroids 3. This one is even more terrible than a previous one and totally Dan Brown inspired — transporting antimatter on asteroid, impacting and causing annihilation. Thank you for this AMA and your time!
DVK: Well the first one is not so crazy, I have seen it presented... the difficulty is that all asteroids are rotating in one way or another. So if you continuously fire the engine it would not really help. You'd need to switch the engine on and off. Very complex. And landing on an asteroid is challenging too. Just using the 'kinetic impactor' which we will test with DART/Hera (described elsewhere in this chat) is simpler. Another seriously proposed concept is to put a spacecraft next to an asteroid and use an ion engine (like we have on our Mercury mission BepiColombo) to 'push' the asteroid away.
As for 2 and 3 I think I will not live to see that happening ;-)
What is the process to determine the orbit of a newly discovered asteroid?
The process is mathematically quite complex, but here's a short summary.
Everything starts with observations, in particular with measurements of the position of an asteroid in the sky, what we call "astrometry". Discovery telescopes extract this information from their discovery images, and make it available to everybody.
These datapoints are then used to calculate possible trajectories ("orbits") that pass through them. At first, with very few points, many orbits will be possible.
Using these orbits we can extrapolate where the asteroid will be located during the following nights, use a telescope to observe that part of the sky, and locate the object again.
From these new observations we can extract new "astrometry", add it to the orbit determination, and see that now only some of the possible orbits will be compatible with the new data. As a result, we now know the trajectory better than before, because a few of the possible orbits are not confirmed by the new data.
The cycle can then continue, with new predictions, new observations, and a more accurate determination of the object's orbit, until it can be determined with an extremely high level of accuracy.
What are some asteroids that are on your "watchlist"?
It's called "risk list", and it includes all known asteroids for which we cannot exclude a possible impact over the next century. It is updated every day to include newly discovered asteroids, and remove those that have been excluded as possible impactors thanks to new observations.
the below is a reply to the above
That's quite a list!! Do you guys ever feel stressed or afraid when you have to add another dangerous candidate (and by dangerous I mean those above 200m) is added to this Risk List?
Yes, when new dangerous ones are added it's important that we immediately do our best to gather more data on them, observing them with telescopes in order to get the information we need to improve our knowledge of their orbit.
And then the satisfaction of getting the data needed to remove one from the list is even greater!
What inspired you to go into this field of study?
I was fascinated by astronomy in general since I was a kid, but the actual "trigger" that sparked my interest in NEOs was a wonderful summer course on asteroids organized by a local amateur astronomers association. I immediately decided that I would do my best to turn this passion into my job, and I'm so happy to have been able to make that dream come true.
this is another reply
DVK: I started observing meteors when I was 14, just by going outside and looking at the night sky. Since then, small bodies in the solar system were always my passion.
As a layperson, I still think using nuclear weapons against asteroids is the coolest method despite better methods generally being available. Do you still consider the nuclear option the cool option, or has your expertise in the field combined with the real-life impracticalities made it into a laughable/silly/cliche option?
DVK: We indeed still study the nuclear option. There are legal aspects though, the ‘outer space treaty’ forbids nuclear explosions in space. But for a large object or one we discover very late it could be useful. That’s why we have to focus on discovering all the objects out there as early as possible – then we have time enough to use more conventional deflection methods, like the kinetic impactor (the DART/Hera scenario).
It seems like doing this well would require international cooperation, particularly with Russia. Have you ever reached out to Russia in your work? Do you have a counterpart organization there that has a similar mission?
DVK: Indeed international cooperation is important - asteroids don't know about our borders! We work with a Russian team to perform follow-up observations of recently discovered NEOs. Russia is also involved in the UN-endorsed working groups that we have, IAWN and SMPAG (explained in another answer).
If multiple videos or pictures, taken from different locations, are available, then it's possible to reconstruct the trajectory, and extrapolate where the object came from.
Regarding the composition, it's a bit more difficult if nothing survives to the ground, but some information can be obtained indirectly from the fireball's color, or its fragmentation behavior. If a spectral analysis of the light can be made, it's then possible to infer the chemical composition in much greater detail.
I've always wanted to know what the best meteorite buying site is and what their average price is??
DVK: Serious dealers will be registered with the 'International Meteorite Collectors Association (IMCA)' - https://www.imca.cc/. They should provide a 'certificate of authenticity' where it says that they are member there. If you are in doubt, you can contact the association and check. Normally there are rough prices for different meteorite types per gram. Rare meteorites will of course be much more expensive than more common ones. Check the IMCA web page to find a dealer close to you.
Just read through Aidans link to the basaltic rock being used as a printing material for lunar habitation. There is a company called Roxul that does stone woven insulation that may be able to shed some light on the research they have done to minimize their similarity to asbestos as potentially carcinogenic materials deemed safe for use in commercial and residential applications. As the interior surfaces will essentially be 3D printed lunar regolith what are the current plans to coat or dampen the affinity for the structure to essentially be death traps for respiratory illness?
At least initially, many of these 3d printed regolith structures would not be facing into pressurised sections, but would rather be elements placed outside and around our pressure vessels. Such structures would be things like radiation shields, landing pads or roadways, etc. In the future, if we move towards forming hermetically sealed structures, then your point is a good one. Looking into terrestrial solutions to this problem would be a great start! - AC
What kind of career path does it take to work in the asteroid hunting field?
It's probably different for each of us, but here's a short summary of my own path.
I became interested in asteroids, and near-Earth objects in particular, thanks to a wonderful summer course organized by a local amateur astronomers association. Amateur astronomers play a great role in introducing people, and young kids in particular, to these topics.
Then I took physics as my undergrad degree (in Italy), followed by a Ph.D. in astronomy in the US (Hawaii in particular, a great place for astronomers thanks to the exceptional telescopes hosted there).
After finishing the Ph.D. I started my current job at ESA's NEO Coordination Centre, which allowed me to realize my dream of working in this field.
this is another reply
DVK: Almost all of us have a Master's degree either in aerospace engineering, mathematics, physics/astronomy/planetary science, or computer science. Some of us - as MM - have a Ph.D. too. But that's not really a requirement. This is true for our team at ESA, but also for other teams in other countries.
What is the likelihood of an asteroid hitting the Earth In the next 200 years?
Have you played the Earth Defence Force games and if you have, which one is your favourite?
No I have not played the Earth Defence Force games, but I just looked it up and I think I would liked it. Which one would you recommend?
How close is too close to earth? Space is a SUPER vast void so is 1,000,000 miles close, 10,000,000? And if an asteroid is big enough can it throw earth off its orbit?
DVK: Too close for my taste is when we compute an impact probability > 0 for the object. That means the flyby distance is zero :-) Those are the objects on our risk page http://neo.ssa.esa.int/risk-page.
If an object can alter the orbit of another one, we would call it planet. So unless we have a rogue planet coming from another solar system (verrry unlikely) we are safe from that.
Are you aware of any asteroids that are theoretically within our reach, or will be within our reach at some point, that are carrying a large quantity of shungite? If you're not aware, shungite is like a 2 billion year old like, rock stone that protects against frequencies and unwanted frequencies that may be traveling in the air. I bought a whole bunch of the stuff. Put them around the la casa. Little pyramids, stuff like that.
DVK: If I remember my geology properly, Shungite forms in water sedimental deposits. This requires liquid water, i.e. a larger planet. So I don't think there is a high chance to see that on asteroids.
