> NT security descriptors with these access control lists and nested security groups are better than just 3 roles user/group/root in Linux.

I’ll bite. POSIX permissions are lousy, and NT permissions are mostly worse. It’s way too easy to mess up, and it’s way too hard to specify a sensible policy like “only a specific user can access such—and-such path”. At least NT can restrict directory traversal.

S3 got it right when they deprecated object-level ACLs.

> This makes launching new processes and opening files more expensive due to the overhead of access checks,

fork() is terrible and slow. CreateProcess is overcomplicated, but creating a process directly is a vastly better design IMO.

Huh? Linux has had proper multithreading support since NPTL, which was a long time ago. Windows, in contrast, didn’t have reasonable support for multithreading on systems with >64 CPUs until Windows 11:

https://learn.microsoft.com/en-us/windows/win32/procthread/p...

I assume this is related to the way that Windows leaks all kinds of bizarre threading details into the user ABI.

I will grant that Linux’s original threading was an abomination.

> Related to the above, CreateRestrictedToken kernel call for implementing strong sandboxes.

Eww. The Windows sandboxing scheme is IMO an overcomplicated mess. Seccomp is not particularly friendly, but it does exactly what it says on the tin, and I would be far more comfortable running untrusted user code under seccomp than under Windows restrictions from token, jobs, integrity, etc.

I ran Instant Meshes over a model of Mount Chimborazo and it did an okay job. Although the mesh was fairly uniform with its quads, the topology looked weird. Like the typographic equivalent of "rivers" running through the mesh. I decided to keep the imperfect topology, with some amount of decimation, because it looks better.

Democracies function on the notion that most people have no idea what they're talking about, and vote randomly. The few who do know what they're talking about will all vote the same way, so most of the time the right answer will prevail.

There are a lot of problems with that assumption. Thus far it seems to work out better than the alternatives, but we'll have to see if that continues to hold.
Its really only important because you need it to truly understand probability and statistics, which you need to really understand how computers work.

Interesting - here in Japan the consensus is that the level of English went down, as we had a few years of no tourists and no language assistants.

this is why, when i go somewhere i prefer to either stay with locals couchsurfing, or when i stay longer, rent a room or an apartment. i don't travel around but stay in the same place, make friends with locals, join their events, etc.

i intentionally don't read about the places before going there, to avoid influencing my experience by the subjective reports of others. especially reports of other foreigners.

i'll never experience the life and struggles as a local, especially not when the culture is very different, or the language or its a developing country. at best i get to experience what living in that place as a european, an expat, is like.

but, where i am able to make friends or become part of a local family, i still get way more insights than any tourist would.

while traveling in japan (where i was couchsurfing) i met a young european who claimed to have learned things about japanese culture that generally no foreigner ever finds out and his japanese friends would always be surprised when he told them about some of the things he learned. i could not verify his claim of course, but it was interesting nonetheless.

But a distant observer could also make the same measurement of the CMW background and see themselves at rest. And yet we could be moving away from either other at relativistic velocities, due to the expansion of the universe.

Due to this relative motion we will see different ordering of events at different locations, despite both being at rest relative to the CMW background, so we can’t really say there is a global timeline.

The thing is that the CMW background isn’t global, we don’t see the same background as a distant observer. CMW photons that are passing us now will take time to reach a distant observer, and vice versa.
I'd be skeptical that any videos or educational programs would help someone who is in crisis and contemplating suicide. Like you mention, actual support from real people who care is probably necessary.

Suicide hotlines are the primary place to find a real person who can listen, if someone doesn't feel safe seeking support from anyone in their life, which can happen for a variety of reasons.

The effectiveness of hotlines is still under debate I'm sure, but there are tons of studies that I'm sure are worth looking into, if this is an area of interest of yours and you want to do some reading.

Satisfaction and Mental Health Outcomes Associated with a Large Regional Helpline https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8749345/

The media projects a misrepresentation of reality into people's minds.

People believe it is representative, they literally link to it as proof of their claims.

In this way (and there are many others), reality is simulated.

Another way is Indirect Realism, knowledge of which is rarely in working memory.

Another way is that people believe there is only one possible form of simulation, as in "the" simulation theory.
For a few reasons: there are lots of ways to abuse those features, which unfortunately some people would take advantage of; we want to preserve the history of the threads rather than have them be gutted or anachronistically edited; and because wholesale deletion would be unfair to the other commenters who participated in a thread (pg wrote about that way back: https://news.ycombinator.com/item?id=6813226).

That doesn't mean we don't care about protecting users with privacy and other concerns—we certainly do, and like I said we take care of these every day. We just try to do it with more precise tools than wholesale deletion.

It's fundamentally a tradeoff: we're trying to balance the community interests of a public forum with the need to protect individuals. There's no perfect answer, but we're committed to both sides of it. Of the people who ask us for these things, well over 90% end up satisfied. Probably over 99%, but I don't want to make claims I'm not sure of!

OP has a point. It depends on your frame. Some areas require far more specialized knowledge than others. If your specialization were something incredibly complex like quantum physics, you'd probably find ridiculous mistakes in 99% of mainstream sources. OTOH, articles about business or tax law may have far fewer lay errors, so you would be mistaken to project the popular information error rate in your own field onto popular reporting in every other field.

Typically, getting into a graduate program is difficult and has an additional bar past graduation, and unless you are a great student you only TA entry level classes you have to master very well anyways. Especially in CS, graduate student is a paid job, too.
At least in theory, while the journalist isn't a subject matter expert, they have spent time reporting on the same domain. They know the people who are experts, and work under an editor who has worked in that field for decades. They should be able to validate any facts and be able to put them into context.

As newspapers have gotten hammered there are fewer and fewer people who actually do that, and more and more bloggers with loud opinions and few facts. Many good sources have gone defunct or given up trying. But there do remain a few sources of decent journalism, where the reporters and editor really are better informed than most laymen.

Smart roads and car speed limits are obvious solution and is being worked towards in Europe.

Despite vivid imagination, there is 0 reasons for you go 10-20% over speed limit, ever.

Why should you endanger everyone when you are in emergency? Why overtake someone if they are driving within 10% of speed limit?

If you want experience speed - get trained and go to a racetrack.

There's no reason why your car (and road agency) shouldn't exactly know speed limit and state of every single road.

> You do occasionally get the real experts, but more often then not, you just get another mediocre human like myself that just voiced their opinion

Most of the comments experts make are just stating their own opinions as well. Take any credible expert in any field and you'll find equally credible experts who completely disagree with them. When experts are communicating with non-experts they're often really bad at explaining which points are just their opinions versus more widely accepted facts, and just as bad as explaining what other equally credible expert perspectives exist on a topic other than their own. They also tend to be pretty bad at explaining where the limits of knowledge in their field are as well.

I would suggest that the ego boost of being a highly regarded expert also tends to make these shortcomings worse with a lot of people, that increasing credibility and reputation can have the effect of increasing dogmatic-ness. Of the topics that I'm somewhat well informed about, I know very few "experts" who are good at explaining the perspectives of their field in a reasonably balanced way, I think Roger Penrose is quite good at doing this, but even he's not perfect and experts with his level of humility are not very common.

Gonna have to go against the grain here. That younger half of the youth you are referring to here are also the same people the article is referring to that get all their news from social media, aka mainly from Instagram and TikTok and distrust MSM. And I think it would be correct to say that those social media sites did more to shape their views than reflect it, considerng how statistically speaking the majority of people had no opinions on such a complex topic before 10/7.

This very much would be a prime realization of the "social debt" the author is talking about, the mass polarization and instability caused by the overreliance on such networks, and the divestment can be argued to be an direct attempt to restablize things onto a common ground. In many ways it's already quite a liberal approach by divestment rather than a straight ban.

For me personally, I've unfortunately turned to the opinion that the "accuracy" of what consumes ultimately is going to be defined by the individual, not the source. I'm reminded of the Sapir-Whorf Hypothesis, in that yes, of course these networks can influence one's views, but it's not deterministic. If one seeks the truth, one can easily just read from other sources freely availiable on the internet.

The problem here is that most people, including many in this thread and in HN I'd argue and perhaps myself, are not interested in the truth. The problem isn't that people are using TikTok or Instagram, the problem is that they are ONLY using TikTok or Instagram. Nobody reads actual articles instead of headlines. And that's because for most people, including many in this thread and HN and myself, we're here just to consume for entertainment, or to confirm our own priors. Why would we question our own beliefs? It's hard work, and there no real consequences if we get it wrong. We can retreat into our social circles and be told it's okay for it. Face it, the majority of people ARE easily manipulable, most in this thread included. People are only going to seek the truth if their job depends on it, and that is only going to include a narrow slice of domain knowledge. Outside of that, everything really is just noise.
Glad to see human ingenuity at work here! Pictures in TFA remind me of scenes from the movie The Creator.
Say that someone was measuring their own brain data at home using an EEG headset. What DIY/low-cost clinical solution might be able to provide biomarkers (AKA data that you've timestamp-synced to brain data to help a multimodal model) for breath rate/depth? Anyone familiar with the research or relevant companies, or have a wacky MacGyver proposal to get it done on the cheap? My first guesses:

1. Wearing a sticker on the chest seems right out, but a fannypack/messenger-bag like device that fits under a shirt could work. Could also be a good addition to an overall mobile-monitoring setup for EEG data -- you could even move the batteries and bluetooth components from your head/belt to the square of your back. This would obviously only work over a shirt though, which seems like it would make getting high quality breath data harder.

2. I mean... dare I just ignore the physical sciences and aim a high quality camera at myself? To what extent is a microphone in your glasses + footage of your chest rising and falling enough? Sorta doubting anyone here has experience here but you never know!

3. I vaguely know that people measure things with lasers -- this could be enough for measuring breathing while seated at a desk perhaps! And surely the most accurate by far, disregarding noise from clothing.

If I ever get to this point, I look forward to trying all these before hitting up google scholar for the boring easy answer...
