I can confirm that coaches, admin, and parents are still pulling the whole "oh little Bobby's not got a concussion, he's just falling asleep in class and having obvious memory problems (true fucking story) because he's really tired, not because he took a terrible hit last Friday—he's fine to play in the next game" shit. Even after all the revelations about the risks of CTE and other brain-related harm from repeated concussions.

Then there's the issue of discipline. The stereotype of athletes getting a pass on bad behavior or a little "help" on grades, because enforcing the rules would mean they'd have to miss a game or two, is based on real behavior that is very much alive today, not some relic of 1980s teen movies.
So which do you go with when they disagree? If your eyeball sees a landmark that you believe puts you at point X, but the GPS says you are at point Y, which do you believe?

For me, absent any other facts, I default to trusting the instrument over the human. I think the risk that the is human misidentifying a landmark is greater than the risk that a ship's GPS is malfunctioning. Again, absent any knowledge of hacking/spoofing in the area.
I feel like goalposts are being moved, many excuses present and ideas that 'we should just wait a few months and Russia will collapse". There was a lot of talk after the war started and sanctions implemented that Ruble will collapse and that's it for Russia. Both from politicians and economists. The opposite happened. Russia seems to be doing just fine and we're all struggling.

5 year high today for Ruble. I just don't know what to think.
This is ignoring federated football. Rugby. Baseball and cricket have more games... But probably far fewer injuries and seem really able to muster fans.

Don't get me wrong. I'm not fully against football. But praising the sport that has more money spent on it for reaping the rewards of said money feels... Not that charitable to other sports.

Edit: I feel ashamed to have omitted basketball I'm my list. :(
Where do you get your 60% humidity ceiling from? I live in Singapore these days, we currently have 80% humidity (and that's fairly normal). We have much less problems with mold here than in Britain or Germany.

(In Germany, problems with mold were usually in winter, anyway.)

Yes, bathrooms with neither windows nor fans are annoying.

> Sure, but the goal is to do that in a controlled manner. Every outlet needs an inlet, and that inlet can either be a dedicated one with a filter (via ERV) or cracks, crevices, and air leaks around your house that you can't see. By puling in uncontrolled outside air you risk moisture buildup in those areas that can lead to mold and rot.

Eh, the air will mostly be pulled in either through another open window (good), or through the same window you are blasting the hot air out of (slightly less good), because your fan doesn't form a seal.

I don't really see how you are getting your moisture build-up. You only really get condensation on the walls, when your walls are colder than the air.

> Unless your interior air is humid, because the house lacks even the most basic form of humidity control. Then those air leak spots cool the area they're leaking in around which then makes condensation from your interior humidity.

I never heard of anyone having that problem in summer, and never had it myself.

I have no clue where you are taking your worries from.
I feel for the student writing this piece and I'm sad that they've developed some bitterness at their advisors and the entire field (which I read in the piece, even if it wasn't the intent.)

Everyone needs to understand something important: a PhD is first and foremost an apprenticeship. It is your opportunity to study under someone who has done a specific kind of research, and learn from that person. If that relationship isn't a good fit, the PhD itself won't be a good fit: it's like trying to learn neurosurgery from a cardiac surgeon. You cannot fix this with reading or online lectures, the apprenticeship is the whole point.

Occasionally I run into students who have these advisor mismatches and my instinct is to try to help them. However what I've learned is that good intentions (try to advise a student who is interested in a different area) don't actually translate to good outcomes. I am monomaniacal (only) about the research that interests me, and that doesn't translate into other areas I'm less familiar with. They will be frustrated with my lack of expertise in those other areas, and I will end up frustrated by my inability to properly advise them. In the worst case, that bad fit can turn to resentment against the entire scientific process (I see this process starting in the post above.)

If the author of the post wants to pursue a PhD, I would first urge them to stop for a while and not think about research: just do something else. When and if they've reached the point where they are bored to tears with whatever they're doing (I recommend taking a "real" job for a while) -- and can only think about the research they're missing out on -- then go figure out whose papers are actually exciting to them. Then go find out how to work with that person, whatever it takes. Sometimes there are ways to work with someone that don't require a formal PhD admission, and enough persistence can make the difference. I'm not saying this is easy. The point is: don't do it because it's easy, do it because you want to do it enough that it doesn't matter if it's hard.
I think the natural progression of war is going to be remote controlled systems. Drones are for flying.

Remote Controlled land and water units would also work.

There are multiple reasons why it's the future.

1. Cheap to make

2. Can be smaller since they don't have to have space for humans to sit in them, which might increase ability to carry things, longer range etc.

3. Because humans don't have to be inside of them they can also go a higher speeds, maneuver faster without human body limitations

4. If a drone goes down, the drone pilot can man another one. All that training and knowledge is retained. Human operated vehicles have a high probability of losing their occupants.

5. If 5,000 drones get destroyed, it's lost money. If 5,000 military personnel gets killed it appears much worse in terms of optics, value of life etc.

I'm struggling to find the purpose of this reply.

Do you believe that saying "no fair!" invalidates the superior outcomes for home-schooled children?

If billions of dollars of state funding and the teachers' aggregate decades of university education can't overcome this obstacle (which did not seem to be a problem when children in one-room schoolhouses routinely used to learn Latin), I'm wondering what other advantages anti-home-schooler central planners need, in order to force their sub-par solution on parents?

I know I'm being ... obtuse. But, seriously -- if it takes 1 or 2 hours a day to "keep up" with the standard curriculum in grade school, and "schooled" students are sent home with 1 or 2 hours of homework, after they attend "school" all day -- what is the purpose of sending kids to these institutions?

:)

The Japanese light novel "Shin Sekai Yori" ("From the New World") explores a world where a small proportion of people develop incredibly powerful psychic powers.

Spoilers:

In it, the government follows TFA's first three methods of achieving stability through means that anyone today would consider immoral and brutal, eventually driven more by fear than reason. The story explores the question of how to balance morality with survival.

As for the article, I don't see it as an apology for a panopticon. In fact, the author blatantly mocks the morality and likely political framing of a panopticon in describing a hypothetical one:

"If suspicious activity is detected [by the freedom tag], the feed is relayed to one of several patriot monitoring stations."

The problem with the article's argument is that it ignores non-apocalyptic problems that are still bad. We could spend a lot of time, resources, and political capital on establishing a world government. But we already use a lot of time, resources, and political capital on fighting disease, providing food, and fending off conventional wars. We can't relent much on any of those, or else we end up with a shitty world anyway.

I like the typology of apocalypses. Those can help in planning. But the list of solutions aren't feasible.
For most of those products, a commodity server is more reliable than the software itself. A straightforward hourly backup with manual recovery is adequate for most orgs.
This. High quality advice from an expert at a shop, who knows where to find even bigger experts, is absolutely worth paying extra for. The problem is: how do I know which shop has that expert?

And sadly, a lot of companies which have built up a stellar reputation over the years, at some point turn to cutting cost while milking their reputation into the ground.
Or they could not live in fear amd do what they want. I wouldn't have sent what they sent, not out of fear, but out of pride and respect for myself. Fear isn't the right reason to not send the pics, honor and respect (for both others and yourself) is the right reason to not send them.
> The use of std::mutex (especially in frequently accessed structures) will bring your application to a grinding halt.

Not necessarily. It really depends on your problem domain and how you architected your solution.

For example, a basic producer-consumer can suffer if you implement it with a common non-thread safe task queue where all consumers and producers have to lock a mutex to push/pop. However, adopting a queue whose pushes and pops can be performed independently without any contention, and using work-stealing consumers that manage their own work queue are enough to eliminate contention to a residual level.

It all depends on your problem domain and how much time and effort and thought you're willing to invest in a problem.
What does this even mean? Who follows you around?
That was an analysis? That was a lazy regurgitation of luddite talking-points that you'd hear in pubs after a few drinks.

Advisors also have to start somewhere. There will always be a first PhD student who works on something everyone has only vague ideas about. I have worked with such students and they are genuinely a different kind of person from other PhDs. They require little to none guidance and have very strong opinions on how to do their work. I believe OP was a poor choice for this position.
PhD is an apprenticeship to do research. If we left it until later in life, we wouldn't have anyone trained to do research.
>Does each child have their own, adequately sized, room with a study desk to work in and concentrate? During the pandemic it turned out to be a real problem that children who had to share rooms had issues following streamed lectures.

I had a small that I shared with two brothers. My desk was minuscule. I had top grades.

>Do the children, particularly those of working age (14 and above, but especially 16 and above) have to work actual jobs to make pocket money or contribute to household income?

My family was so poor at a time we didn't have the money to pay the mortgage and the bank wanted to take our house. I had top grades.

>Are the parents largely absent from their children's lives because both parents have to work full-time or worse jobs just to make ends meet?

My parents were and are apathetic to my existence. I had top grades.

>Can the parents invest time and money into furthering their children's education? Can they sit together with them in the afternoon/evening and work through homework problems? Can they afford side education, playing instruments or similar activities that have been shown to have a positive effect on education?

None of that existed in my house. Nobody helped me doing homework and nobody sit with me exploring my life path. I rented instruments and asked as few money as possible. I had top grades.

>Do the parents have enough money to feed the children? Hundreds of thousands of students alone in New York depend on schools handing out free lunches, which turned out to be a massive problem during the pandemic.

Admittedly, even in poverty we never were hungry.

>Poverty causes stress - not just from being cooped together in too small living spaces, but also in food insecurity, increased fights between parents over the stress, or in the worst cases from literally being homeless.

This I wholeheartedly agree, that's why the "money doesn't make you happy" is such a lie.

I know my tone was rather flippant but the relationship between money, stress and academics is so important to me. And by the way, even after all these top grades, and a Physics degree and speaking English, French, Italian and German and whatever I haven't escaped poverty. I'm back living to my parents at 27. It seems like the best way to make money in Italy is to inherit it.
I love the WW1 analogy!

I think anti-drone drones are going to quickly move to being autonomous. No one's going to worry too much about "accidentally" taking down a simple drone and the threat of just one kamikaze drone getting through is too high to chance a delayed human reaction. Plus jamming or other measures will make direct control more difficult. An army will likely have a few circling "CAP" drones overhead at all times.
Thanks for running the experiment!

Your results seem rather strange, though. I wonder where the extra heat came from? Thermodynamics say that heat moves from hot to cold places, unless something intervenes.
Interesting. I thought "clean energy" generally didn't include nuclear. Also, is hydro really "clean energy"? In the US at least, biomass is the largest source of "clean energy". I'm betting it's even more for germany as they don't have the rivers we do to generate hydro power.

I feel like this must exist and I just haven’t found it, but I’d love a tool that can automate seeding a staging/local db from production.

It would need live in a vpc to access the prod db, but then expose itself to access slices of anonymized data that can be used to restore external dbs.

Essentially a configurable pgdump that includes the ability to anonymize personal info, take recent slices of data, and serve the data all in a way that still protects direct access to the original data.
> equivalence offers little analytical and practical benefit

I disagree, but that's irrelevant.

Considering things equivalent is default, if their properties are the same - in case of concurrency/parallelism, I think I have clearly demonstrated how every concurrent algorithm is parallel, and vice versa.

If you're claiming that a distinction should be drawn, the burden of proof is on you. What is the fundamental difference between concurrency and parallelism?
Nominally related: shout out to the awesome Mycroft search engine plugin project.

I wish it got more attention. I never understood why Mozilla built this half-assed search plugin feature on the addons site instead of integrating with Mycroft when it had already existed for years.
Yeah, but what if they get hit? The danger isn't in the speed of these bikes, but in the speed of surrounding traffic.
The opening line about not having prior exposure before PhD is something that makes me wonder if author did have industry experience prior to this undertaking, there are application and network security hands-on problems that can be solved with quantum computing. I have zero practical experience with quantum computing myself but I can count at least 2-3 practical projects I could work on before starting PhD in that field. I wonder if the problem here is author going after PhD in the field without having an idea of what problem author can solve by using quantum computing experiments/projects. (instead of finding solution to problem, looking for problems and having time to experiment/research solutions.)

> studying the underlying Quantum Mechanics and understanding this new concept of how physical reality might look like under the hood (there are actually multiple interpretations of that, from Probabilism to the popular Many-World-Theory) has been eye-opening.

> I was asked to find something that does not require so much understanding of Quantum Computing

Sounds like QM was a new subject to you and you didn't know/understand QM enough to do research in an adjacent field. Not sure why you'd pick a field that you don't have much background in to do a PhD in. I'm not sure what advice you expected your supervisors to give.
You finished a PhD, you should know how much weight his accusations would be given seeing as he isn’t a professor. I kept my mouth shut when I heard my co-advisor was badmouthing my other co-advisor’s research and the result was the committee blowing up at the prospectus. Sometimes it pays to be proactive.
FWIW, the rules are so strict now that football's probably safer than it's ever been to play.

Additionally, I've read a ton of studies of this stuff and everything that I've found said the risk at the high school level is virtually nonexistent when compared with the general student body. In the college and professional level where everybody is bigger, stronger and faster it's an entirely different situation.
That's interesting about the blocksize. I was never impacted by that because I mostly use dd for writing large files, and a large block size always made more sense to me. For example, if I wanted to test writing a 1 GB file to a flash drive, I'd do something like:

dd if=/dev/zero of=/mnt/test.data bs=1M count=1024

Overall, a very informative article though!
I think the big difference here is the "How". In general, I'd agree, but the article seemed pretty honest that this was a small project (in manpower, not necessarily scope); yet they did everything right by supporting the project. It was also honest about not using the language, but its tools.
This is classic survivor and selection bias. You likely didn't notice all of the people sidelined by this.

I suspect selection bias also plays in to all of the negativity. But variety reigns and places that had more offerings almost certainly had more success.
It can happen both ways. My PhD ended up being a computer vision project and while I could program better than most new grad students I didn't have any significant experience with image processing, visual geometry or CV (or ML for that matter). I did know that going in, but at the time I was more interested in working on instrumentation (which I got to do as well). As a PostDoc I flipped the other way, after a couple of years in industry I joined a group where I brought some specific expertise to the group that they didn't have. Good strategy for getting work in my experience.

This is fairly normal: you get some funding to do a project and you have to hire someone with experience, though in this case the PIs were experts in the domain of application. That's reasonably common for cross-discipline projects, but in this case you really have to trust that your hires know what they're doing and you need to be able to assess their work without deep knowledge of the techniques used.

PhDs can be absurdly specific and many are complex enough that you can't really study them until grad school. Many universities don't teach quantum computing, but as a physicist it's probably assumed you have enough of a background to understand the material.
sqlite authors say that for many scenarios plain sqlite beats filesystem traversal times.

So for some applications it might be faster to put "files" in a database (where primary keys are hierarchical full paths) as opposed to actually use the filesystem.
Reading this, I couldn't help but recall Feynman's quote: "If you think you understand quantum mechanics, you don't understand quantum mechanics."

I love cussing and discussing quantum theory / physics / computing. And Feynman is 100% right.

Speaking of a statistical reality is not racism. It's just reality. One can debate of the causes - societal, genetics, single motherhood, whatever - but the fact remains that it is reality.
Yes, most of the consensus I've seen is that even if a modern ship somehow failed to intercept those missiles (which it probably wouldn't have), a modern and well-trained/motivated crew should have been able to immediately shut down the flooding and damaged caused by two comparatively small explosions, and prevented the ship from sinking. An entire ship sinking because of that level of damage is what was most mind-boggling, from what I understand.

Regardless, the point of the article is less about the specifics of the Moskva, so I think it's a fair hook.
for quadrocopters, you want a hunter-killer drone with some kind of a net or tape to jam the propeller.

for plane-like drones... guess something similar. gliders may be super hard to spot and will still be somewhat effective without a working propeller, so tough luck.
It has only gotten easier to host your own content or find someone to pay to host your content. Web3 does nothing new here and doesn't actually help. What web3 does is take people's desires for those types of solutions, and turn them into a way to scam people out of money.

If you want to make it even easier to control how your content is hosted, join one of the many open source projects that are building free tools that make things easier.

Edit: While I not the biggest fan of WordPress on a technical level, that piece of open source software has done far more to democratize the ability to host your content on a platform you control than the entire Web3 ecosystem put together.
The vector registers are powers of two in size, but both ARM SVE and RISC-V V allow you to conveniently process any vector shorter than the register size -- by setting the VL register in RISC-V or by using a vector mask in SVE (RISC-V also does vector element masking) -- or longer than the vector register (by looping, with the last loop possibly being smaller than the vector size)

"What if you have a 4-vector and want its dot product?"

Dot product with what?

Of course on RISC-V V you can load two 4-vectors into two vector registers (perhaps wasting most of the register if it has 256 or 512 or 1024 or more bits), multiply corresponding elements, then do an "add reduce" on the products.

But that's not very interesting. Don't you want to do dot products on hundreds or thousands of pairs of 4-vectors? Load the 0th elements of 4 or 8 or 64 etc into register v0, the 1st elements into v1, 2nd into v2, 3rd into v3. Then the same for the 4-vectors you want to dot product them with into v4, v5, v6, v7. Then do v0=v0v4;v0+=v1v5;v0+=v2v6;v0+=v3v7. And then store all the results from v0.

People used to short SIMD registers look at vector problems along the wrong axis.
I have a quasi-HOA that has something to do with the county extending public sewer/water here a few years ago. But it's like the federal government during the wild west era. They keep to the "nice" side of the neighborhood, and don't hassle us out here on the frontier. The house in front of mine hasn't had siding up for the better part of a year.

My parents live in a real HOA and it's miserable. Lawyers had to get involved recently when they got into a fight with the HOA over cutting down trees on their own property.
Seems like sunlight and substrate is much more common than seagrass is. I found this paper [1] that talks about the difference.

It estimated the area of suitable sunlight and substrate to be 4,320,000 km2 but estimated seagrass coverage of 177,000 km2.

I think this big difference indicates that there are additional factors at play.
