Some perspective from the interviewer side: just tell us straight up that you're panicking. While I can't guarantee that an elitist smug interviewer is going to always respond appropriately, I at least would make an effort to try to help you calm down, be it by removing trivial blockers (e.g. fixing some syntax blooper for you) or trying to paraphrase whatever you're trying to say but not finding the words for, or asking leading questions in the hope of bringing you back on track. A little dirty secret among interviewers is that we're supposed to be accountable for managing the direction and quality of the interview (i.e. one that devolves into a awkward staring contest is a failure on the interviewer's part for not interjecting appropriately)

Ultimately, it is in the company's best interest for an interviewer to look past things like nervousness-induced panic attacks, and I've heard on numerous occasions that good interview sessions involve the interviewer and candidate working together rather than adversarially.

You picked one example where it doesn't fit while there are at least 8 EU countries that did exactly what I said. BTW yes here in Central/Eastern EU we deem France very very leftist, just few small steps away from full-on socialism.
I have chronic lung issues. It's not snideness. People who use fake masks put my life at risk. I've literally spent the past two years being terrified.

So yes, I do have breathing and anxiety issues, but my breathing issues are because I've crappy lungs, and I'd prefer to _not_ be around those who consider my life less worthy than their own.
What you are suggesting is wildly speculative and not backed up by the science. Individuals not in high-risk groups nearly always make a full recovery from COVID infections.
The impression I have is that many web developers who learned their trade in the past five years know how to build with React (or maybe another front-end framework) but don't know how to hook up a JavaScript-free form using GET or POST - or even know that it's possible and sometimes desirable to do that!

The neo-nazi obsession with symbols and dog whistling is so.... stupid. They've got like 37 different stupid ways to say "Heil hitler". The Klan were the same way, with a bunch of code phrases, symbols, and secret handshakes that sound like they were invented at an elementary school birthday party.

I know the point is to fly under the radar and gaslight people into second guessing things (They couldn't possibly be using the OK sign as an in-group signal.... right?) but how do you do these things and still think you're the cool kids fighting a big bad evil instead of the obviously pathetic cowards you are?
I get this point of view too, but my problem with it is that it is based on a series of prejudices (kids are more valuable than adults) and not some fundamental ethical principle. Maybe I just like things that in theory tidy up nicely and practicality is a better approach, but I think ethical decisions should be able to be fundamentally summarized in principle without relying on specifics of the situation unless they fundamentally change the scenario in some way.

I just feel like it's trying to force the 'A-ha!' moment that the first rails demonstrations had for most developers at the time, when that ship has long sailed. I'm probably just jaded. There's nothing actually wrong with what they're doing at all, it's just 20 years later and there's an overwhelming feeling of 'is this all we've achieved?'
I misunderstood your "buy this NFT" call to action. Should've read the paragraph before it more carefully. I'm sorry about that.

I think there are a couple of key differences that you’re underplaying.

First, for usage of cars in society, there’s a nice gradual curve where an early slow unreliable car is still somewhat useful, and a faster car is a bit more useful, etc, and that’s what allowed them to get off the ground (as it were). There’s a vastly higher threshold before jetpacks start being usable and useful.

Second, cars are relatively fail-safe in that if you take your foot off the accelerator the car will coast to a halt. Lots of cars can easily come to a safe stop together -- traffic jams are bad but not immediately life-threatening.

Jetpacks aren’t nearly as failsafe because if you stop flying you need to land (or more likely, crash-land).

Planes have the same two advantages over jetpacks, because even a slow or unreliable plane is useful because it can carry cargo; and most planes can glide a bit which helps reduce the risk of crash landings.

It's interesting that Argentina is in the same decline Venezuela was in (and still is), just with some years of latency. Both countries are in the same economic region, one would think someone would learn from having a hyperinflation near them.

A lot of Venezuelans immigrated to Argentina years ago, and are now leaving Argentina and immigrating to other countries. Some are even going back to Venezuela now that everything there is in dollars and the situation seems to be stabilizing. A somewhat popular opinion is that the country is very corrupt but you can live with it if you earn in dollars.
Yeah, sorry for not being more clear, but I wasn't talking about that person, or the piano, or about the odds of someone contracting COVID from surfaces. I was using the quote to illustrate what I see as a difficult pair of values to balance that situations like masks in classrooms, or other shared-space restrictions, really throw into painfully high relief: how do we collectively, as a society, balance our own personal inclinations (i.e., in this case, to play the piano, or in OP, to let our kids go unmasked) with whatever risks we impose on other people (i.e., in this case, which for the record I totally agree is excessive, that the shared piano will help spread disease; or in the outer case, that fewer masks in the classroom could lead to, e.g., more sick grandparents, or teachers)?
Risk = probability * loss

So even though the probability is very very low, the loss (consequence) is extremely high (say an order of magnitude) which makes this a high risk.
Thanks and couldn't agree more! Its great to see how these models work in harmony with a vector search engine like Weaviate.
Stealing is sometimes okay, but usually the kinds of people who try to justify it do so because they infantilize criminals, which is maddening.
This explains it a lot better than the OP. (At first I was wondering if it had to do with "blockchain", because of the word "block" and the OP seeming like the kind of "solution in search of a problem" I associate with blockchain).

But now I get it. Standardized content plugins across apps, basically?

Sure, makes sense. I wish I thought any of the platforms involved were interested in making any investment at all in interoperability.
Water hammer is a big lever that has a hammer on one side and a big bucket of water on the other side. Bucket gets filed by a water stream, gets heavier than the hammer and lifts it, and then at the lowest point (of the bucket) it is mounted in such way that the water spills and the hammer drops, resetting the machine. No precision technology needed, they could do it in stone age.

You can do the same thing with fireplace and water and it's certainly doable with ancient technology, but I'm not sure it's worth it when you have more running water than industry needs anyway.

Another thing they could do is Heron's steam turbine geared in such a way that it does useful work. Also not sure if it's worth it.

This trick (using low power to lift the hammer slowly and dropping it quickly) can be adapted to use any inefficient power source - hamster powered mills are possible ;)
contact tracing only works when a pandemic is in the hundreds, maybe a few thousand tops. After that it becomes too intractable to trace and also yields little benefit.
> 1. No more SMS and TOTP. FIDO2 tokens only.

SMS are bad due to MITM and SIM cloning. In EU many banks still use smsTAN, and it leads to lots of security breaches. It's frustrating some don't offer any alternatives.

However, is FIDO2 better than chipTAN or similar? I like simple airgapped 2FAs, but I'm not an expert.
The risk profiles that I refer to are both collective and individual - they're correlated for pretty clear reasons. Nobody is experiencing the spread of the disease in a vacuum.

Omicron's risk profile doesn't seem to be the same, looking at the numbers available on the Google chart I look at. We're seeing a lot fewer deaths per cases. That's not to say everyone should throw caution to the wind and do whatever they want, but it's disingenuous to say the math hasn't changed at all.

COVID cases are acting like a marketplace. People take different actions when the numbers/unknowns change, and that's not surprising. I know I'm doing a lot more outside of the home than I was when COVID first started, and that I'm not unique in that respect _at all_.

Not prescribing any course of action, just tossing out what I've been seeing.
Anyone with a counting board also has zeros, as empty places with no counters, and ancient people had no problem understanding and using the concept of zero in calculations (though most probably would not have considered zero a “number” per se). They just didn’t write explicit zeros in their permanent serialization format.

But there are certainly plenty of mathematical ideas and tools ancient people didn’t know about: they didn’t have a convenient method of manipulating algebraic expressions and equations; they had only the most rudimentary version of differential/integral calculus; they didn’t have group theory, linear algebra, complex analysis, etc.
According to the CDC the COVID-19 infection fatality rate for children is 0.002%.

https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/burd...

Children can spread the virus to adults, but adults who want to be vaccinated have been for months now. And since everyone will be exposed anyway it hardly matters who does the exposing.

Yeah, the implication being that white Christians making white-only churches in the name of Christianity would be pretty offensive, and by analogy cis women making their own women's spaces that specifically exclude trans women in the name of ~feminism is offensive.
Why are you ignoring the multiple times I've talked about the effects that aren't directly related to the children? They're carriers too, and that matters, on top of everything else.

And the institutions I trust do not agree with you that we're "rapidly approaching" any such loss of value from masking in schools. That's just straight up wrong.
2021, definitely :) Apologies for the typo.
No, I’m not trying to shut down the ‘conversation’. I’m just saying, you should try to figure out if you actually have a good reason for feeling that way.
In robotics specifically, understanding how methods like QR factorization work (and fail) is necessary to debug robot code, even if roboticists rarely have to implement QR factorization from scratch.

Take a look at GTSAM, a library used widely in robotics for mapping and localization. To read the intro tutorial for the library, you need to understand most of the topics listed in the OP repo:

https://gtsam.org/tutorials/intro.html

If anything, the Michigan course doesn't cover enough, since it's missing Lie theory, which is becoming standard in robotics code these days.
It's also not the solved problem your snark implied. I mean, someone's been working on it for decades and his solution is fly over water as much as possible!

(As other posters have alluded to, parachutes won't save you at low altitudes. In the mean time, it's further weight on your back on a device which is already difficult to control, and not really optimal for releasing next to jets of hot kerosene either)
Skydivers solved that problem with parachutes.

Um, it says "can" and not "do". It says "can" because it depends entirely on the person wearing it. Trained professionals in a short term controlled environment, I am sure they work great. Kids in a school, not worth it. The neglect in "frequent hand-washing", "physical distancing", and other habits are going to lay waste to any positive impact the masks may have. No one is going to spend the time to instill the necessary habits to make masks worthwhile in school.
And a lot of new cars from this century are specifically designed to not be reverse engineered in some cases to the extent of having encrypted CAN messages or having to pair a failed module with the ECU cryptographically to discourage 3rd party replacements.

Well, the CLI tools are not really couple to Proxmox Backup Server and could be built for most somewhat modern Linux distros, quite possibly also other *nix like systems.

The whole tape management is in the common PBS API, so that'd be a bit harder to port but not impossible. For example, I made some effort to get all compile on AARCH64 (arm) and while we do not officially support that currently there are some community members that run it just fine.

So, maybe, but could require a bit more hands-on approach. If you run into trouble you could post in the community forum (<https://forum.proxmox.com>).
"CURIs"?
I tried selenium then playwright for a .Net project, selenium wasn't easy to work with. Playwright was good but for some reason which I don't recall exactly (could have been because it had to redownload chromium everytime we deployed). I ended up switching to puppeteer and I ended up very happy with it.
In general, as someone else mentioned in the context of agriculture, the low-hanging fruit are probably innovations that aren't especially complicated or require possibly uncommon elements and other material. Stirrups for example in Europe. Also mostly abstract (but possibly useful) scientific and medical knowledge.

Anything that requires a long technology tree to implement effectively is going to be hard.
Never completely. Spent material is also casing for the actual fuel, for instance, which can't be reused. In the fuel itself, there is some uranium and plutonium which can be reused, but there are also atoms produced by the fission which are not useful.

For instance, a possible output of an uranium atom splitting could be one Krypton atom and one Baryum atom. Both are radioactive, and the path for krypton to a non-radioactive atom includes one step with a half-life of ~10^6 years.

There is also waste from the plant itself. When you decomission a plant, the vessel steel is going to be radioactive and needs to be stored safely.

There are plenty or other waste types that can be stored more or less safely. Some can be reused, some not.
> You're likely getting into ADA territory there. Masking during a pandemic to permit at-risk kids to continue to go to school sounds very much like a "reasonable accommodation" of the sort schools are required by law to provide.

I agree it is a reasonable accommodation, but also cannot imagine sending my own kid to in-person school if they were one of the rare high-risk kids, especially before vaccination was an option. Masking helps over a population, absolutely, but if you're a particular person who's prone to and weak against infection, the way it's been spreading in school even with masking—yikes. Masks and the (mostly lame and questionable, for the simple reason that doing better would have meant building new schools—I saw some hilariously pointless and even alarmingly counterproductive guidelines forwarded from teachers I'm friends with) distancing practices aren't anywhere near sufficient for that case, IMO.

OTOH, lots of people don't have the option to stay home and watch a high-risk kid. So masking it is (again, I am mostly very in favor of it!) but man, that sucks for those kids and their parents.
Depending on what test people are getting, there may be a good portion of the population who have gotten Omicron but don't know it if they had very mild symptoms.

Plenty of us have off days, or may feel a little sick but don't assume it is Covid because of expecting extreme reactions even when it absolutely could be due to its symptoms overlapping others and many people being affected very little or even being asymptomatic.
There's a few major issues with disposing of nuclear waste into the sun. First and foremost is that if the rocket explodes you'll contaminate a huge radius with dirty bomb like material. Probably not great.

Further, if you do decide to launch it, it takes significantly more energy to shoot it out of the solar system than towards the sun. [1]

It is the responsibility of public health to take all of these variables into account before mandating countermeasures. The fact that people are constantly placed in situations where mask effectiveness is reduced or in some cases completely eliminated should be evidence that mask mandates are pointless when applied at scale.
IIRC they have recently gotten all the (major) approvals, but they haven't started to bury anything there yet.
it's very likely a reference to the US oil embargo.

Nuclear is neither cheap, sustainable (limited resources and storage problem) nor is it quick (takes at least a decade to add it to the grid)
I would argue that it is possible and meaningful. AFAIK extended grapheme clusters are well defined by the standard, and are very well suited to the default meaning of when somebody says "character", so, given no other information, it's reasonable to reverse a string based on them. I guess the issue is "reverse a string" lacks details, but I think that's different from "not meaningful".
The stability issues could easily be fixed with more closed-loop control. The much more serious issues are heat and the limited fuel supply.
In Salt Lake City lots of people flew paragliders. But they also have a great place to fly from that's close by.

Even the most optimistic data we ever had was ~90% reduction in infection. That the vaccines on the market were not sterilizing has been evident since the start.

There are a lot of examples in that thread, too. She's been confidently predicting hitting herd immunity, no need for boosters, last wave, etc. sort of stuff for a long time.
Sweden used to have their own uranium mine, but since it was cheaper to buy it than to mine it they shut it down.

The exact same reason why planets don't immediately fall into the sun
Funny to watch the Atlantic change directions on COVID over the last few months. I go back and forth on masks. In general I find them to be a minor inconvenience, although I believe they're more inconvenient for me than most because I'm blind and no matter what I do they always fog up my glasses.

But while masks themselves are mildly inconvenient, harsh mask mandates and restrictions become much more of an annoyance quickly. Try taking a 6 hour flight with a 2 year old that's required to keep his mask on the entire flight, and when he takes it off (because he's 2, of course he's going to take it off) the flight attendants threaten to turn the plane around and ban you permanently. That gets old quick.

I was in a coffee shop the other day and my mask broke. Everyone takes their mask off to sip their drink or eat their pastries, but I was immediately asked to leave when the functional mask I walked in with broke. They didn't have any extras, I wasn't carrying around more than one mask. It was embarrassing. It's pretty easy to grow tired of these mandates when your situation deviates slightly from the norm.

At this point, I'm in favor of a "protect yourself" direction. If you're concerned, put on an N95 and a face shield and sanitize your hands often. It's clear that shutting down society to the point necessary to restrict the spread of COVID is not feasible, and all the halfway measures we've taken haven't achieved their stated goals. It's just a nuisance at this point.
Omicron may only be less deadly because of the precautions we're currently taking. Reducing those precautions could very well slingshot Omicron into being the deadliest variant, if it isn't already by sheer numbers.
You could tack it shut just enough to get by, but not actually full seal it. For that matter, you could probably just stuff the outer flap down inside the envelope and maybe put a very small piece of tape on it. Same difference in the end. The point being, mailing yourself an envelope doesn't really prove anything about the provenance of whatever is found inside later.
Reversing a string is still meaningful. Take a step back outside the implementation and imagine handing a Unicode string to a human. They could without any knowledge look at the characters they see and produce the correct string reversal.

There is a solution to this which is to compute the list of grapheme clusters, and reverse that.
