L2ARC is a cache. Cache is actually part of its full name, which is Level 2 Adaptive Replacement Cache. It is intended to make fast storage devices into extensions of the in memory Adaptative Replacement Cache. L2ARC functions as a victim cache. While L2ARC does cache metadata, it caches data too. You can disable the data caching, but performance typically suffers when you do. While you can put ZFS metadata on a special device if you want, that was not the configuration that Percona evaluated.

If you do proper testing, you will find ZFS does beat XFS if you scale it. Its L2ARC devices are able to improve IOPS of storage cheaply, which XFS cannot do. Using a feature ZFS has to improve performance at price point that XFS cannot match is competition, not cheating.

ZFS cleverly uses CoW in a way that eliminates the need for a journal, which is overhead for XFS. CoW also enables ZFS' best advantage over XFS, which is that database backups on ZFS via snapshots and (incremental) send/recv affect system performance minimally where backups on XFS are extremely disruptive to performance. Percona had high praise for database backups on ZFS:

Finally, there were no parity calculations in the configurations that Percona tested. Did you post a preformed opinion without taking the time to actually understand the configurations used in Percona's benchmarks?
In ML everything is a tradeoff. The article strongly suggests using dot product similarity and it's a great metric in some situations, but dot product similarity has some issues too:
- not normalized (unlike cosine simularity)
- heavily favors large vectors
- unbounded output
- ...

Basically, do not carelessly use any similarity metric.
This piece makes a lot of unsubstantiated claims.

Just because you are putting a child in a siloed environment doesn’t mean you’re teaching them that everyone else is beneath them.

If you are homeschooling and not teaching humility, kindness, etc then you’re doing it wrong.

> In reality, what stops bad behavior is regulation because in reality, people do not have infinite time and infinite information to assess each thing they consume.

Reputation is much easier to destroy and bad behavior is much harder to hide today than 50 years ago due to the easier spread of information.

There is still a huge spectrum of business behaviour that is not violating regulations. In the aggregate businesses who please their consumers more will thrive compared to those that don't.
We live in a social climate where we can't even assert ourselves of someone's gender based on their name out of fear from a very local special interest group that has far reaches into public education system and this is another big reason why parents who can't afford private school opt for home schooling.

The fact that parent had to edit their comment and could not call a man a he answers the article's question very well.
VLMs are great - I have been able to use it for a similar project too [1]. And it's only going to get better. Congratulations on the product launch what's your VLM model for this?

No one seems to be talking about the website itself.

While as a concept, I absolutely love "X by Example" websites, this one seems to make some strange decisions. First, the top highlighted example is just an overly complicated `cat`. I understand that it's meant to show the versatility of the tool, but it's basically useless.

Then below, there's 3 pages of commands, 10 per page. No ordering whatsoever in terms of usefulness. There looks like there's an upvote but it's actually just a bullet decoration.

There's also a big "try online" button for a feature that's not actually implemented.

All in all, this is a pretty disappointing website that I don't think anyone in this thread will actually use, even though everyone seems to be "praising" it.
Probably sue the failed startup owners for negligence?

If DankStartup left all your HR files lying around in their office and the guy who bought it five years later found them, well, DankStartup should have shredded them. It'd sure be nice if the cleaners shredded them for you, but I wouldn't count on it (nor make them liable).
That is not my experience. I use FF exclusively, I can't remember the last time I used Chrome.

I have over 1200 tabs open at the moment, including at least 100 youtube tabs, and mine runs fine even with a bunch of other stuff running.

I do find that if I go over 150 windows open then things start to become problematic, but I think that's because my GPU is only 8Gb.

CPU is usually at about 10% on an i7-12900k.
The key terms don’t change so I usually just grep Nixpkgs in nvim and usually have a lead on where to start. Obviously it’s a bit more work than copy/paste from the arch wiki but generally more popular config changes will have an nixos option available.
> Nix currently has the most packages of any distribution, see https://repology.org/

This is a meaningless point. Different distros split packages differently.
With bluesky bursting on the open source (and not yet enshittified) microblogging scene, mastodon needed to regroup and reposition.

This organizational change seems aligned and is a good sign that there is ambition and appetite to build further, starting with solid governance.

The first chapter of the re-decentralization of the online experience is closing. Lets hope there are many more and curious what the shape of new things to come will be.
I can't see these in this article, at all.

I think what it say is under "Is it the right kind of similarity?" :

> Consider books.
> For a literary critic, similarity might mean sharing thematic elements. For a librarian, it's about genre classification.
> For a reader, it's about emotions it evokes. For a typesetter, it's page count and format.
> Each perspective is valid, yet cosine similarity smashes all these nuanced views into a single number — with confidence and an illusion of objectivity.
Sure, 10mph is 16kph. 15mph is 24kph. The “10-15mph” assertion top of thread is just incorrect
The teachers in this school don't speak Spanish. The Spanish speaking children are struggling, and the rest of the kids cannot proceed at the same rate.

I'm not pretending to have solutions, and I'm certainly empathetic for all involved. Just stating the reality that this is a suboptimal learning environment.
I know an extended family of third world impoverished immigrants who became middle class by basically all going to nursing school. It is almost a joke that all Filipinos become nurses, it's almost fool proof way to have at least a car, shitty apartment and decent food to eat. It's worth looking into for anyone who is stuck, none of it is particularly difficult to learn although it is hard work.
I’ve seen this in on-ramps but surely you can understand why duplicating traffic lights isn’t an ideal solution.
The OP explicitly called out logins. Are you being intentionally misleading or just dense or what?

> Doom wasn't developed with open source in mind, was it ?

Not sure - Wolfenstein 3D was open sourced in 1995 (two years after Doom was released).
This seems like such a strange product decision - why clutter the interface with such a niche use case? I’m trying to imagine OpenAI’s reasoning - a new angle on long term memory maybe? Or a potential interface for their agents?
> 150 years ago, the average person was illiterate

Not true in the case of the US, which famously adopted a culture of universal literacy earlier than the rest of the world. By the mid-19th century, literacy rates among whites were not much different than they are today. It is one of the bright spots of American history; they took literacy very seriously for complicated historical reasons. Their book consumption per capita was also the highest in the world by a very large margin back in those days, which lends evidence.

It may or may not be relevant to your point, but at least in the US the idea that the average person was illiterate is ahistorical. They were the best read population in the world 150 years ago, and took some pride in that.
How do I know it’s retrieving and analyzing market data and not simply hallucinating something that plausibly reads like good advice? How is it doing the advanced analysis?

Yeah, well, you know, that’s just, like, your opinion, man.

Out of curiosity, how do you refer to the logical fallacy of begging the question?
I don't see the problem here.

We've already settled on DNS being the auhoritative authentication key for everything. If you bought the domain then you've bought the corporate identity. It's working as designed.
for kids in early development, their skill level in all the other subjects later will be essentially determined by their linguistic ability. math is a language. there is research that shows benefit to bilingual programs, but there has to more structure than just dumping esl kids in there with everyone else.
I love using my AirPods, but they have become insanely buggy as of late (like, they will crash while playing audio; audio stops, then transparency cuts out and comes back after a reboot) and I often come to dead or dying AirPods when I try to use them.

This is not the case for AirPods 1. I still have my original ones. You can leave them in the case for months and both will still have a charge.
This is interesting, although I am a little confused about the purpose of ChatGPT with this feature.

We already have many implementations where at a cron interval one could call the GPT APIs for stuff. And its nice to monitor it and see how things are working etc.

So I am curious whats the use case to embed a schedule inside the ChatGPT infrastructure. Seems like a little off its true purpose?
OK, but the issue I was bringing up has nothing to do with funding for schools.
How about outside the city? This is a statewide test, how are other areas doing?
I've been doing it for ~20 years off-and-on. Initially I thought I'd find an audience/community that resonated, but never did. So no.

My experience has been that I have to post to HN about 6 times to have a shot at making front-page, and even when I do I feel like from the comments that I didn't succeed at communicating what I was trying to.

I also don't get any organic interaction. (https://think-twice.me/)
Literal children are incapable of forfeiting their rights by being "violent and disruptive", and it would be insane if they could because they can't possibly begin to understand what they'd be giving up. Clearly that right is sometimes taken from them anyway, but that's neither the fault or a failure of the child.

Often kids who get their right to education taken from them are failed by their parents and/or by the schools, but the blame cannot be placed on the child for that. Every child, excepting those with significant mental illness or intellectual limitation, can and should be successfully educated. Any educational system that is incapable of handling a child's tantrum or helping a child in crisis is a failed system.
This looks very much like a Connection Machine. A red LED would light up when its corresponding processor was active.
What is the biggest drag on your time and effort as a PM?
Hi, I'm doing some research for a product, primarily around how technical PMs handle their work life.

Wanted to understand a few things but the key item is understanding the biggest drag on the time of a PM? What do you find yourself doing more and more that shouldn't take as much time as it does?

Also if you have time then these are the other questions:

2. What do you find are the consistent barriers to program/project success you see repeated?

3. If there was one piece of information a product could give you that would make your life easier related to your engineering teams, what would it be?
Squeak Smalltalk has several automatic runtime optimizations and compilers like JIT, parallel load balancing compiler [1], adaptive compiler [2] and a metacircular simulator and byte code virtual machine written in itself that allows you to do runtime optimisations on GPUs. The byte codes are of course replaced with the native GPU instructions at runtime.

There are dozens of scientific papers and active research is still being done [1].

I've worked on automatic parallel runtime optimizations and adaptive compilers since 1981. We make reconfigurable hardware (chips and wafers) that also optimises at runtime.

Truffle/GraalVM is very rigid and overly complicated [6].

With a meta compiler like Ometa or Ohm we can give any programming language the runtime adaptive compilation for GPUs [3][4].

I'm currently adapting my adaptive compiler to Apple Silicon M4 GPU and neural engine to unlock the trillions of operations per second these chips can do.

I can adapt them to more NVIDIA GPUs with the information of the website in the title. Thank you very much charles_irl! I would love to be able to save the whole website in a single PDF.

I can optimise your GPU software a lot with my adaptive compilers. It will cost less than 100K in labour to speed up your GPU code by a factor 4-8 at least, sometimes I see 30-50 times speedup.

> Don't blame the average teacher though - they are doing what they have budget for and what they've been directed from administration.

It's worth discussing the administrators and the budget (though our budget is much higher than the national average), but why should we reflexively dismiss concerns about the teachers? There are advanced students who only get acknowledged as such when the teachers tell them "don't do that, we haven't learned it yet."

There's a large difference between trying to engage advanced students with limited resources, and not trying to engage or even acknowledge advanced students at all.
this is the experience i see at our local schools. english as first language kids are bored and not challenged. the class is moving slower because half the kids are only learning english for the first time at school. “modern” progress ideology is to not separate the students by ability anymore and there’s less accelerated tracks

Yes, but it de-prefs it as I understand it, and refines the model with better, more fine grained objective measures. There's room in this new space for a "fat, but fit" category.

Login credentials are more than just the email used, and should not be conflated with identity. To be honest I'm surprised google isn't using a uuid tied to the account for the identity given to others, especially since internally google knows and treats it as a separate account that just happens to have the same e-mail. The e-mail should only be used as metadata for contact info.
No phones period is stupid. Just get them a jitterbug or a startac
Yeah, I was thinking the same thing. Who is physically doing the homeschooling? The rich tech people? Their spouses?

It sounds like what he is criticizing is just extra-private private schooling or something like that. As distinct from homeschooling by parents, which is the more… eclectic version the author grew up with.
Thank you for demonstrating the point that there are constraints and complications that are difficult to appreciate from the outside. The law generally disagrees with you.
It wasn’t that bad creating some new derivations my first week with Nixos, I was so used to Arch where I had maybe a handful modified pkgbuilds over a decade.

For better or worse it was a positive experience, especially when you usually already have a pkgbuild to go off of.
The sad part, the "do not care" attitude is infectious. Maybe there is a bright-eyed programmer who just joined and who wants to make UX better.

They are full of enthusiasm, but nobody (around them) cares.

They are fixing the most annoying bugs that users complained forever about.. but they is not recognized, because nobody (around them) cares.

They hope to show a good example but nobody cares. Instead they get negative feedback when instead of blindly implementing horribly-designed feature, they are trying to fix it so it won't be so user-hostile.

Eventually they give up and stop caring. When asked what they like about the job, their answer is "stability" and "job security".

US to Push TSMC and Samsung to Tighten Flow of Chips to China
It's very clear you're out of your element on this, and you have multiple people with an actual math background telling you the objection is somewhere between meaningless and wrong.

The takeaway from trying to really nail down a definition of "integers" (or anything, really) is going to be something along the lines of "if it quacks like a duck up to unique isomorphism, it's a duck". The encoding is not important and one frequently swaps among encodings when convenient. In any case, no one who knows any math is going to say to a child that 3 and 3.0 aren't interchangable outside of some extremely specific contexts. In fact that's not even encoding: it's notation. They can be literally equal, not just equivalent. Those particular contexts aren't ordained, and e.g. propagation of uncertainty is "better" than significant figures if you're doing engineering anyway.

Writing something like '10/3=3' is likely to trigger the mathematicians because lots of people get confused about what '=' is supposed to mean (and often use it to mean something like "next step indicator"). '3=3.0' not so much.

I remember it being a pain in the ass on Fedora which tracks closely to mainline. Frequently a new kernel version would come out that zfs module didn't support so you'd have to downgrade and hold back the package until support was added.

Fedora packages zfs-fuse. I think some distros have arrangements to make sure kernels have zfs support. It may be less of a headache on those

Our kid started riding a pedal bike on their own at 3 years, 3 months thanks to the sheet method.

We started on an indoor bike-like ride along, thing.

Then a balance bike outside, then a small kids bike with no pedals, then pedals with freewheel, (no coaster brake) but two hand brakes and the sheet.

I used a muslin baby blanket for the sheet.

We did not take the support away suddenly at any time though.

We jogged with them a lot, constantly ready to catch her. I did, a handful of times save her from wrecks. This took a fair amount of athleticism, attention and reflexes.

But it also allowed us to talk about core bike safety and new nuances like “watching your white circles” (the handle bar ends were white) and make sure not to let them touch anything while riding.

Our kid got really comfortable pedaling and toward the end of the sheet use, I mostly just let it hang jogging along. It was the sense of security that allowed plenty of practice in advance of going without.

One day they just picked up their bike and started riding across the playground. Plenty of miles since then no wrecks yet.

We were not going for precociousness, but it was really great to get it down so young. I can ride my old coaster bike alongside when it’s dry, and we’ve done night rides.

We did not push any step of it, but did have the next bike available to them to see and look at and talk about. It was very smooth, I wish something like this process was available when I was a kid.
>Over a 100 year old grind, schooling fixed all that. Why can't it keep going?

Schooling has fixed all that, and still works just fine. Just not in America, because that country is rapidly self-destructing. Schooling is still working fine in the rest of the world.
