> Small note. There are methods of compression and encoding that allow for scalability. There's some fancy signal processing you can do to encode multiple <framerates / resolutions / compression qualities> into a single bitstream without necessarily storing redundant data.

A big note. All of this wasn't used by YT because they've always used a widely used standard codecs and media containers. All the lower qualities of videos they provide use storage nearly the same as the highest one (so 2x total), all bitrates are the same for all videos. As for download part, the players in auto quality would get first a maximum quality they can for current download speed, if there's a room or connection isn't stable - also 480p version, and if the speed was enough to download current and next chunk in lower quality it would download the best and switch to it over on completion (there were a times when player was downloading the whole video in the best quality after it had finished in an optimal).

> the sort of awful, buggy things (formatting/file wise) that people try to upload that break everything.

YT has very narrow list of formats allowed to upload with hard breaks in converting process, especially for the audio.
Why not? How is it any different than two web requests causing a multi-threaded application server to send two simultaneous writes to the database?

If you use triggers for validation, you can rely on your database's MVCC to resolve any conflicts between triggers. Note that this is significantly more performant and robust than the application trying to resolve, or even notice, those conflicts.
This is one reason why HMAC-SHA1 is still safe.
A lot of the drivers are older than their Linux port, which makes mainlining from the start not really make sense. Nvidia and PowerVR I know for a fact are in that category.
> Huh. so shortly after the story broke, I bought a bunch of SMCI.

Likewise. Almost doubled my money before taxes.

My reasoning was that essentially no tech infrastructure company has significantly suffered financially due to security incompetence and it was unlikely that it would start with SMCI especially since it wasn't even being claimed that the company was in on it. Nothing even seemed to allege any particular error on SMCI's part, certainly not one that essentially every vendor isn't also making.

The idea that the report could be wrong wasn't a factor for me, only that the marketplace would continue to not care. (I find it hard to believe that it's entirely wrong: I am unwilling to believe that major state intelligence orgs are so incompetent that they are never backdooring hardware in that manner).
That page has a major layout issue for me: it appears to have a fixed height with no vertical scrollbar, so the bottom portion of the page is completely inaccessible to me even if I maximize the window.

Is that part of what you're trying to test, or is it just an unimportant artifact of the test page?

Also, I'm not actually on board with the visualization -- it just makes everything more confusing and harder to follow. But that might be my personal idiocy.

I quit most social media a few months ago and have always blocked ads the best I could, and I completely agree. A sense of alienation is felt.

What's more, is that I "realize" that none of the things I was missing really matter. I do not care, at all, that I missed Captain marvel. Nor that I missed my favourite TV show -- I can always watch it later, if I really want to.

Seeing other people then care about such trivialities is a novel experience too.

Fun fact: the passport gates at UK airports appear to be biometric, but aren't. You step into a little gate, place your passport photo page down onto a scanner, and look into a camera for a photograph.

The thing which slows folks down at passport gates (and the reason the best passport control agents don't have a jocular welcoming patter) is the hello/goodbye/talking around the manual "look at your face, look at your passport".

When the gates open at Heathrow and you're allowed through, you'll immediately see a raised bank of desks behind which sit a bunch of officer who are simply manually verifying that the person in the photo appears to be the person on the passport.

I did some digging to make sure that isn't what's happening here (all the articles seem to be very vague about the "biometric" and "facial recognition" part). Here's where I got to:

> Using facial recognition, TVS enables biometric identity verification by transmitting automated queries to locate photos in DHS and U.S. Department of State databases for matching against the unique characteristics of a traveler’s facial features. As designed, this updated capability operates in a virtual, cloud-based infrastructure that can store images temporarily and operate using a wireless network, thereby eliminating the need for the tablets previously used in 2016.[1]

I am really curious about tidal energy projects, since in principle the cost for the wall is linearly proportional to the circumference, but the energy stored is proportional to the area, hence quadratic in price. Roughly speaking a project 10 times as expensive would store and generate 100 times as much energy...

Unlike solar and wind, the tides are very predictable and 2 cycles per day are guaranteed.

The constant false dilemma between nuclear and coal is poisoning the discussions and blinding us from investing in alternatives...

Did the Japanese project for tidal energy get scrapped? Wikipedia is mute about the current status at [1] and doesn't list the Japanese tidal energy project as under construction at [2] either...

Of course you can fix it. I fixed it in Dec 2018 for most such attacks in my safelibc memset_s implementation, but nobody wanted to use it, because securely purging the buffers with secrets via mfence was deemed to slow. So everybody can read your secrets via sidechannel attacks.
These tiny MDS buffers need to be purged with verw or l1d_flush followed by an lfence. This needs to be added to memset and memset_s variants. This is much faster. But it will not happen, libc maintainers notoriously don't care, even crypto maintainers not. Only Linux does.

Well, are we assuming they're spending those 4 hours watching TV passively? Maybe they are. Or maybe they just like to have it on while they do other things.

I know my own kids tend to have Netflix on all the time, but are also playing games, making art, talking to each other, doing chores, etc.

I myself have it on for many hours a night, but I spend almost no time sitting in front of the screen. (Sundays have been an exception for GoT.) It just makes doing dishes, cleaning, and laundry so much more bearable.

That's what these studies always seem to fail to address. The assumption is if the TV is on, you must be staring at it. And that's simply not the case.

I think the person you're replying to was talking about Geometric Algebra, which is more of a project to reformulate all our current vector and tensor notation in terms of Clifford algebras and to move away from using specific representations of the algebra and instead just leverage the algebraic properties themselves.

If you look at how most physicists use the gamma matrices, they are very reluctant to treat them as algebraic objects and rely heavily on their matrix representation. A proponent of GA would say this is like using the matrix

[ 0 1
[-1 0]

everywhere in your calculations instead of just using i and remembering that i^2 = -1. Sure, it's formally equivalent but you'd still miss out on a lot of the beauty of the complex numbers.

For what it's worth, I have a soft spot in my heart from Geometric Algebra, but I think it still needs a lot of notational improvement before it'll ever see any real adoption.

If you're curious about GA as it currently stands, I'd check out Geometric Algebra for Physicists by Doran and Lasenby.

In one case I didn't see the article and in the other it didn't cross my mind. But also, that topic isn't so highly charged, and I didn't see nationalistic flamewar getting in there.

You're asking for a level of consistency in moderation that we can't deliver. I'd have to hold 100x more information in my head to come up with a consistent set of principles that would cover everything we do. Such a set would be inordinately complicated and impossible to explain or defend, so what would be the point.

> I want to read what people think.

Me too. But you can't read everything people think, because comments influence what gets posted in response. If a discussion becomes a flamewar, you're going to get the angry thoughts of the flamers, but lose the thoughts of those the flames drive away. It's a tradeoff—we can't have both. On HN the non-flamey, thoughtful comments take precedence, because that's the only way to optimize for HN remaining interesting. This is one area where I think we really are consistent, or at least I hope we are.

Look at it this way: each post changes the kind of site HN is. The container isn't static—it's altered by what people add to it. Our goal is optimize that container for curiosity. This is a global optimization problem, so it's important not to get distracted by local optima. Our experience with things like nationalistic flames is that while such comments are sometimes interesting (and certainly the topics are of great world significance), the type of discussion they lead to is reliably worse. What we do is: extrapolate the vector of a given comment and ask what its shaping influence is on the site as a whole. Is it to make HN more, or less, interesting? Where more, we either do nothing or steer towards; where less, we steer away. In the case of flamewars, steering away means doing things to prevent the flames from spreading. There are various tools for that—digging trenches, pouring water, etc. Picking which to use where is more of an art and I wouldn't say we're particularly consistent on that level. But the fundamental principle is very consistent—there's only one, and it motivates literally everything we do here.

> No one dared comment on Dave’s behaviour.

> Being in Dave’s bad books meant being denied support. Support for the libraries he wrote. The libraries which powered every clients’ project.

> I was in awe of the respect that Dave commanded.

Now, obviously it's not nice to comment on one's sexual (or fashion) preferences, but sounds like this exact same thing could have happened if Dave was smoking at desk or piling used coffee mugs.

A library that powers the whole company being managed by a single guy who has to answer all others' questions, and selectively denying answers when he feels like, is not a sign of a great programmer. It may not be a sign of a bad programmer (maybe he's just tired of shit), but it's certainly a sign of a poorly run place.
This was literally my plan for a few years. I had a knack for algorithm design, I've changed the direction of teams by writing code alone for several months.. and I really wanted to wear dresses to work for some reason. Fortunately my first breakthrough coincided with starting estrogen, so I got to present my scheduling algorithm to some execs, wearing a blouse and skirt because I felt very secure.

I'm not an asshole, though, and it really doesn't sound like Dave was that mean, other than just having skills and strong boundaries.
All of the major cloud providers have free credits for new customers.
The breaking bad Chrysler/dodge revving scenes were egregious.
And they won't ever in the future, either, unless they buy another content provider or get acquired. Content is getting more expensive every year, and if you don't own it, you're leasing it. People are cutting the cord more as video and voice is becoming less and less desirable. Soon the only things that will matter will be internet and streaming content, and internet will probably become a public utility in the next decade or two. As consolidation continues, they'll have to pull a Netflix, then divest or break up their internet service so they don't have the government do it for them.
> P.S. Why do we still have these silly things in general?

One possibility is a belief that having a security question allows for users to reset a forgotten password without having to involve a help-desk person on a phone call to do a password reset.

> These old cliched questions don't help anything

If your answers are the output from this:

$ sort --random-source=/dev/urandom --random-sort /usr/dict/words | head -5
spindled
antiquities
tumblers
teasing

Which makes (for this example) the answer "spindled antiquities tumblers teasing halter". So you have words for the times you are talking to the human on the phone when they want you to give the answer, but you have random words that joe-hacker is not likely to guess while trying to do social-engineering on the same help desk human.

With a password manager, storing these "random" answers to security questions along with a randomly generated password, is trivial. And if these are your answers, you don't really care what the question happens to be, because the answer you give will have nothing to do with the actual question anyway.
I suspect that Dave's pay was not proportionate to his value to the company.
Intel and AMD don't have to share the same bugs for AMD to be worse.

Consider you've got two sets of vulnerabilities: [1, 2, 3] and [2, 4, 5, 6, 7, 8].

If I label set 1 Intel, and set 2 AMD, then you can see how doing your research on Intel first will make it seem like Intel has 3x the vulnerabilities as AMD - even though it actually has half.
Just so you know, asking if twistors are the future in a thread about Feynman diagrams is like asking if smart watches are the future in a thread about cars. It's pretty off topic.

That said, nobody really knows about the future of twistors in physics. Twistors have some really interesting algebraic properties that may eventually get leveraged in a main-stream theory but they could also just end up being a mathematical curiosity that never has any real impact.

I think I feel pretty confident saying that twistors will never have the cultural / philosophical impact on physics that Feynman diagrams have had (for good or for ill).
In the US, for IRS purposes of "you must give health insurance or pay a penalty", full-time is 30 hours a week or more. (Specifically companies with >50 employees, IIRC). So as long as you're working 30 hours a week you should be getting health insurance same as the full-time employees.

See https://www.irs.gov/affordable-care-act/employers/identifyin...

(Some health insurance plans in fact _require_ people to be >=30 hours a week to be included on it.)

I once bought a book from them and while it was in shipping, the price dropped due to a sale. I called and asked if they would reduce the price on my book and they said no but they said I could order it again at the new price and and then mail back the previous book once it reaches me.

I know. The story I referenced about Humans of New York was exactly that: “I have a degree in theatre and I can’t make above minimum wage. That’s unfair, theatre is important and I should be able to make a living doing that.” I know people personally who are like this, and when you engage with them and say “Have you thought about getting a job doing X at company Y” or “There’s a huge demand for nurses, have you thought about getting a nursing degree”, the response is something like “I don’t want to do that, I wouldn’t enjoy it.” There’s some sort of fundamental disconnect here between how they think the world works and how it actually does.

At the end of the day, free college is not going to solve the problem, and I firmly believe it would make matters worse. With no skin in the game, people will get all manner of ridiculous degrees, and the universities will be more than happy to give them to them.

According to the article, there's a huge disparity just in transportation costs, before wages even begin to factor in:

> Today, Recology, San Francisco’s employee-owned recycling company, pays £230-to-£390 to ship a container of recycled plastic across the Pacific–a fraction of the £2,700-to-£3,100 price tag for transporting that same container across the United States to plastic processing plants that are mostly located in the South, according to Robert Reed, a company spokesman.
No, there is no way this could be done, because there is no way to know which of multiple colliding inputs was the right one. Imagine a one-bit hash function. You start your “decompression” process and read in a 0. What input produced that bit? Literally fifty percent of all possible strings would produce that same output. Without more information, you cannot choose between them. And the information needed to choose correctly is exactly the same amount of information in the original input.

Agree, but I don't say that lambda calculus is not interesting, I say that there are so much more alternatives, unexplored. If we do the same with the IC of Lafont, I think that the possible (right patterns) of rewrites (which preserve the no of half-edges and nodes) are about 10^13.

A conjecture, which I don't know if it holds water, is that analoguous to CA, Wolfram style, perhaps 1/3 (or anyway a significant proportion) of the 10^13 possible graph rewrite systems, alternative to IC, are Turing universal.
