There are quite a few options for non-head-tracked wearable display type headsets. Those generally get pitched as "portable cinema" though, e.g.:

https://goovis.net/products/g3max

(This particular one uses USB-C for video input, but they also sell an HDMI adapter for it.)

Of course, in practice it's just a display and can be used for any purpose. I do appreciate the fact that you don't have to mess around with all the usual VR setup chores with these - it's really very plug and play.
Karpathy says:

> The single number that should summarize your expectations about any LLM is the number of total flops that went into its training.

One thing I've been curious about is whether a model that's trained well beyond the Chinchilla level of compute will suffer more from quantization. All of that information has to live somewhere within the weights, so it stands to reason that you may have to keep more bits of information to keep that performance benefit.

If so, it would also mean that a smaller model that's been "overtrained," but which can't be quantized without suffering quality loss isn't necessarily cheaper for inference than a larger model which isn't overtrained, but which can be aggressively quantized. I haven't seen anyone discuss this, but maybe there's a paper on it.

If you could characterize what level of overtraining leads to quality loss at different levels of quantization, you could possibly figure out a more optimal model for overtraining. E.g. if you train with 10T tokens and you see quality loss at 4 bit, and you train with 20T tokens and see quality loss at 6 bit, you can fit a curve to those data points to estimate the maximum amount of tokens the model can train on with the current methodology.
Facebook is spreading russian propaganda and yet russian does stuff like this. russia is confused.
It is more than a wild guess, it is a guess based on the outdated perceptron model of the brain.

Active dendrites the that can do operations like xor before anything reaches the soma, or use spike timing, once again before the soma are a couple of examples.

SNNs, or spikey artificial NNs have been hitting limits of the computable numbers.

Riddled basins as an example, which are sets with no open subsets. Basically any circle you can draw will always contain at least one point on a boundary set.

This is a much stronger constraint than even classic chaos.

While I am sure we will continue to try to make comparisons, wetwear and hardware are cheese and chalk.

Both have things they are better at and neither is a direct replacement for the other.
A lot of people flag anything behind a paywall. Which the WSJ always is.
Eh, embedded and sensor-fusion devs are making bank working at Waymo, or VR at Apple or Meta. It's less about the field itself and more about big-tech salary-leveling (and insane profits)

What makes you think they don't hold that data anymore?
Sorry, but I hate this article just because of the stupid click-baity title. The author doesn't have half a clue what I already know.
When I saw the title, I immediately thought of the show "Invincible" which had abysmal animation, and lo and behold, its right there are the top of the list.
Leaving aside the frequency of the event, how about we look up the rules for your jurisdiction, and then we get a better idea about whether the exact situation you (and/or bluefirebrand) are thinking about qualifies as illegal?

For example, down in Washington State, I'd paraphrase the law [0] as "store owners can't be sued back if they had good evidence and only stopped the person enough to record information." (Note, that's separate from "citizen's arrest", which comes more from common-law precedents than from explicit statue.)

To be fair, airports were already screening for that pre-9/11.

The tech has gotten a lot better which… should make things faster and easier to pinpoint and locate problematic objects instead of doing random checks?

I think long lines are mainly due to growth of travel and aviation (more planes, bigger planes, and jamming more people in the same plane) without corresponding growth in airport security infra.

If there were lineups at the shops in the airport, they’d build new and bigger shops in no time.
That's a good point, it's easy to get stuck in the mindset that the current moment describes the future.

The Quest is insanely good, for a single person in isolation, once it's up and running. But there's a ton of friction that shouldn't exist before that happens, and Meta hasn't nailed most of the UX here yet. For example:

- App sharing / libraries doesn't work properly yet. (The owner has to secretly log in to each individual app themselves, before anyone else can use it on the device. There is no documentation informing anyone of this requirement)

- Add/ons or DLC also don't work properly yet. (You have to 're-unlock' each individual DLC, for it to share to anyone else on device in something like Beat Saber, for example)

- Child permissions don't work properly yet. (The notification does work, but a parent is not allowed to approve an app from that notification, the child has to entirely shut down and restart the whole device, before an approval takes effect)

- Screen sharing doesn't work, at all. (If you have a child, you just can't ever mirror their view onto a TV or Tablet -- full stop, no exceptions. Which also means, there's no way to help a child who is wearing a headset -- ever). Note that "taking the headset off" triggers a state reset, so a child can't hand the headset over to their parent for help, since the face sensor will kill state the second a face is removed.

- Windowing UI doesn't really work yet. (You can have windows, but only three, and only side-by-side, and only for a select few apps) -- it's more usability-restricted than even stage manager on an iPad. You can tell the Quest is designed around the expectation that you will be in one-and-only-one full-screen game, pretty much the entire time your wearing the headset.

- Online sharing is app-dependent, a bunch don't work. Many more don't work at first, you have to spend 30 to 60 minutes "unlocking" the right to match-make. (making the online/networking more seemless is critical because of the nature of the device -- you can't both look at it the way you might with a TV or PC or Laptop or Tablet, since it's a worn device)

None of this is dealbreaking stuff, none if it needs any kind of "new invention" or anything to fix. But as a product, friction is still really high here, and I can see why it's not necessarily super popular outside of techie/gaming scenes yet.
All instances of POTS showed up across friends with no overlap, on different ends of the country. The several people that came down with bells palsy- also not in overlapping groups. The latter is associated with the covid shots, the former, not as much, as it's also suspected to occur after covid infection as well, though it's hard to trust the statistics. My friends that suspected the vaccine as the culprit were very aggressively dismissed by their doctors, so I doubt many of those reports were ever logged.

I'm glad you recovered, and thanks for the well wishes.
The HN headline is more clickbaitey than the original article, which has a different headline and goes out if its way to point out that Amazon and HBO are likely not the ones doing the outsourcing to North Korea.

> There is no evidence to suggest that the companies identified in the images had any knowledge that a part of their project had been subcontracted to North Korean animators. In fact, as the editing comments on all the files, including those related to US-based animations, were written in Chinese, it is likely that the contracting arrangement was several steps downstream from the major producers.
Cookies are very much alive (still the best way to do CSRF protection). I think you mean 3rd party cookies?
The entire chain all the way down is sanctioned, the US can and will climb up and down that chain to punish sanctions violations. A company like Disney will have to have a Sanctions Compliance Program and like any other compliance regime, there are standards, external auditors, etc. to make sure enough is being done, and "enough" can be a bit of a moving target. If you get caught having sanctioned suppliers, those standards and auditing get kicked up a notch, if you did a really bad job maybe fines or criminal charges.

There isn't ever a sense of "I'm doing enough and therefore the sanctions violations happening are no longer my fault". It's somewhat up to you to determine your risk and tailor your compliance program to address them and to adjust if you're ever wrong.

How guilty you are is a function of how good a job the state department thinks you're doing trying to avoid sanctions violations.
Yeah the practical cases for devirtualization are when you have a base class, a derived class that you actually use, and another derived class that you use in tests. For your release binary the tests aren't visible so that can all be devirtualized.

In cases where you have Dog and Goose that both derive from Animal and then you have std::vector<Animal>, what is the compiler supposed to do?
I'd agree with your

Like all computer system, you cannot remove all risk from the system. But you can reduce it significantly ...

so that we can both agree that the article's statement

It lets research scientists dig into 58m NHS health records – while seemingly doing the impossible and completely preserving patient privacy in the process.

is so much tosh. That being the case, I do not consent to my medical records being used in this way, not that my consent will be sought. "Do no harm" my arse.
Do you have anything more to say on this point?

Given my experiences in Oregon, I'm having trouble thinking of it as sensible, but I'm open-minded.

Finding people that vibe on the same things you are passionate about is really, really difficult. Feedback and just being around people doing stuff I think is super, super important.

One way I'm considering doing this is running a local HN style invite only message board. There are lots of FB groups for my target activity (fishing) but people are notoriously guarded about their fishing spots so I'm thinking maybe a small $5 a month membership will keep the tire kickers out and reduce the riffraf.

Put it this way, if someone was doing this around here already I'd sign up right now. It's not just finding a community, it's finding a CURATED community where the things / people you need are available for you to interact with.
.NET is a particularly bad case for this because it was a decade of few performance improvements, which caused a certain intuition to develop within the industry, then 6-8 years of significant changes each year (with most wins compressed to the last 4 years or so). Companies moving from .NET Framework 4.6/7/8 to .NET 8 experience a 10x average performance improvement, which naturally comes with rendering a lot of performance know-how obsolete overnight.

(the techniques that used to work were similar to earlier Java versions and overall very dynamic languages with some exceptions, the techniques that still work and now are required today are the same as in C++ or Rust)
I'm planning to release this project as open-source.

ESG consultants have more access to more information than is available to investors.
Perhaps we just need an S3 implementation specifically built from the ground up for the data-intensive workloads? Such implementation might use conventional S3 underneath for cost and reliability advantages. Such implementation can also deliver a lot of additional functionality which will also be uniform across cloud vendors like enforcing Iceberg conventions on the server-side rather than on the client side and those pre-conditions uniformly implemented or even a full blown transactions but without breaking S3 semantics? Metering and billing can be also made friendly to those data intensive workloads. The question is: if the overhead of such indirection level, right on the data path, can be made reasonable? This is what we are trying to figure out at Embucket.com

If you have 100 people at the company you should have 19 managers with about 5 people each? And then the CEO has to manage those 19 managers, and has 19 people under them (because what is a CEO other than the person managing what's done at the top level?)? What about when the company has 1000 people?

It's all fine to you should just split it up more, but that only makes sense if you look at the part of the system (company) in isolation, which you can't do. It's intricately linked to the parts around it.

What you're recommending isn't even the waterbed theory of complexity, where you push down complexity in one area and it pops up in another, this is the ostrich theory of complexity, where if you stick your head in the sand and ignore everything then it doesn't matter.
As others have noted, technical and more quality content, especially the one found in subreddits that are more composed in nature is becoming more scarce and rapidly declining in quality. Bots, constant reposts and low quality comments and posts in contrast are rewarded and gain more exposure than ever. "It's just another phase" is a very light way of putting it. Reddit is becoming - maybe arguably has become - a former shell of itself more akin to 9gag than what it used to be.
Youth be youth, innit ;)
It also blows my mind that that, even though DNA seems to just code for proteins and does not store a schematic for a brain in any way that we've been able to decipher so far, human eggs pretty reliably end up growing into people who 9 months after conception already have a bunch of stuff, including visual processing, working. Of course the DNA is not the only input, there is also the mother's body, the whole process of pregnancy, but I don't know how that contributes to the new baby being able to enter the world already intelligent.

It's possible that I'm not aware of some breakthroughs on this topic, though.

A complier will definitely try this, but it's important to note that if/else blocks tell the compiler that "you will run these evaluations in order". Now, if the compiler can detect that the evaluations have no side effects (which, in this simple example with just integer checks, is fairly likely) then yeah I can see a jump table getting shoved in as an optimization.

However, the moment you add a side effect or something more complicated like a method call, it becomes really hard for the complier to know if that sort of optimization is safe to do.

The benefit of the switch statement is that it's already well positioned for the compiler to optimize as it does not have the "you must run these evaluations in order" requirement. It forces you to write code that is fairly compiler friendly.

All that said, probably a waste of time debating :D. Ideally you have profiled your code and the profiler has told you "this is the slow block" before you get to the point of worrying about how to make it faster.
True, but it seems more like it's placing a bet in the VR space like the first iPhone did. No one wanted iPhone v1 forever, and so I think the next few versions of the Vision Pro will be pretty interesting if this is the starting point. It also raises the bar of expectation for other VR/AR headsets. Seems like a net benefit for an area of tech that has been pretty stagnant for a while.
They are 24x200G, which is already outdated. Everything we are doing is currently 400G (via 8xCX7 cards running in ethernet mode) and 800G at the spine. 800G NICs, which will come with PCIe6 next year and cuts the number of connections down.

What I'd prefer is the connection is through the UBB/OAM baseboard, such that you have PCIe connections. Look into what GigaIO and Liqid are doing. There is a 3rd option that is even cooler than those two, but I don't want to mention it here. ;-)
Yes; different continent.

Honestly if N Korea had a cheap/low-barrier remote visa it might be attractive. I would imagine having an oppressive authoritarian regime looking at you as a prime tax slave might mean none of the prols would risk getting their head chopped off to mess with you. Meanwhile labor/rent/food gotta be hella cheap.
Wow that spam bot is quite creative! Looks like they've figured out how to create a green account, and perhaps bypassing the spam detection by having each new account only post one spam message.

I'm sure dang is really busy right now.
They were animating stuff? For money? The thing that hits me the most about this, I think, is the depravity of it all.
Yep, guess the admins will have a busy day. Seems 10000s of accounts being created and used to spam ai sex bots.
At least for me, I've always associated preferring mouse inversion with growing up handling BB guns. When you're lifting a rifle up, you are pulling back/contracting on the right arm. When aiming, to go up you nudge the right hand down, or nudge up to point down.
The reason Reddit can't really do this (and they tried) is because people notice and react. If they turn reddit into Facebook they'll lose their "clients", particularly the "productive" ones. I'm not going to use Reddit if old.reddit.com breaks or if I can't sort by new/top. I'm sure there's hundreds of thousands if not millions of users like me. People using the new layouts might "interact" more, but it's a shallow interaction. They don't write long form text, they don't post anything original etc. If they want a link farm they can have it but it'll gradually empty out and turn into a cheap tabloid-esque aggregator that copies twitter's trending. Maybe Reddit can't be very profitable after all and they should scale down their expenses and keep it as it is.

Interesting that this wasn’t baked in as a preventative method for repeat usernames.

Which is also ironic because why would this guy reuse the same username for his little spam campaign when it can be nuked in one line of code…

Though I'm curious about the claim that it "replaces your toothpaste". Isn't the abrasive act of brushing, with the toothpaste, the main reason why tooth brushing is useful? I feel like just spritzing your mouth is leaving a lot of food particles and plaque on your teeth?
This is hyperbolic but there is a sliver of truth there; "the best" music is not necessarily on exclusive dubplates, but if you don't put in any effort to discover new music you may simply never encounter the vast ocean of incredible art that exists outside of the mainstream. It's totally fine if someone doesn't want to do that (they probably don't care about music that much) but anyone who does so will be well-rewarded.

There is nothing necessarily wrong with being incurious, but it's not an interesting or impressive position to hold.
I think it depends on what you’re building and who’s building it. We’re all benefitting from the fact that the designers of NGINX made performance a priority. We like using things that were designed to be performant. We like high-FPS games. We like fast internet.

I personally don’t like the idea of throwing compute at a slow solution. I like when the extra effort has been put into something. The good feeling I get from interacting with something that is optimal or excellent is an end in itself and one of the things I live for.
I mean, that's kind of why I tried to emphasize measuring things yourself instead of depending on tribal knowledge.

There are plenty of cases where even the "slow" implementation is more than fast enough, and there are also plenty of cases where the "correct" solution (from a big-O or intuition perspective) is actually slower than the dumb case. Intuition helps, you have to measure and/or look at the compiled results if you want to ensure correct numbers.

An example that really annoys me is how every whiteboard interview ends up being "interesting ways to use a hashmap", which isn't inherently an issue, but they will usually be so small-scoped that an iterative "array of pairs" might actually be cheaper than paying the up-front cost of hashing and potentially dealing with collisions. Interviews almost always ignore constant factors, and that's fair enough, but in reality constant factors can matter, and we're training future employees to ignore that.

I'll say it again: as far as I can tell, you have to measure if you want to know if your result is "faster". "Measuring" might involve memory profilers, or dumb timers, or a mixture of both. Gut instincts are often wrong.

Raku (perl6) was a chance for Larry Wall to fix some of the limitations of the perl regex syntax, as you would expect from the perl heritage, it behaves similarly.

~ > raku -e 'say "foobar" ~~ /^ <[a..z ]> +$/ ?? "yes" !! "no"'
yes
~ > raku -e 'say "foo\nbar" ~~ /^ <[a..z ]> +$/ ?? "yes" !! "no"'
no
~ > raku -e 'say "foo\nbar" ~~ /^^<[a..z ]>+$$/ ?? "yes" !! "no"'
yes

- ^^ and $$ are the raku flavour of multiline mode

- ~~ the smartmatch operator binds the regex to the matchee and much more

- character classes are now <[...]> (plain [...] does what (...) does in math)

- perl's triadic x ? y : z becomes x ?? y !! z

We can have whitespace in our regexen now (and comments and multiline regexen)

my $regex = rx/ \d ** 4 #`(match the year YYYY)
'-'
\d ** 2 # ...the month MM
'-'
\d ** 2 /; # ...and the day DD

say '2015-12-25'.match($regex); # OUTPUT: «｢2015-12-25｣␤»
