> I could start self-hosting an AI chatbot

I was surprised nextcloud has a whole bunch of ai plugins

https://apps.nextcloud.com/categories/ai

funny, I run nextcloud but don't add all these plugins because they require* you to install from the cloud.

* there's a way to install apps locally, but you had to install the app store and it quickly became very complicated.

Seems almost incredible that no one is pointing out the YT incentives behind this. YT has a war on two fronts: ad-blockers and in-video sponsors. That is because in-video sponsors don't get YT money, so they want to be in the monetization loop. So, by decreasing the views, sponsors are now less attracted to in-video sponsorships and YT ads look better in comparison.

Author here,

Wow, I didn't think this would HN. I actually planned to do the advertisement rounds only after the final ICLR submission.

This is our attempt at creating a model which understands multiple physics, which is in contrast to PINNs and Neural Operators, which focus on much more narrow systems.

Obviously, the biggest issue is still data (3D and real-world problems), but I think we and a few other groups make significant progress here.

I stumbled over this a few times, mostly when cleaning up older code. This basically just means that using the ?. member access no longer dictates what is possible on the right side.

Property reads were fine before (returning null if a part of the chain was null), method invocations were fine (either returning null or just being a no-op if a part of the chain was null). But assignments were not, despite syntactically every ?. being basically an if statement, preventing the right side from executing if the left side is null (yes, that includes side-effects from nested expressions, like arguments to invocations).

So this is not exactly a new feature, it just removes a gotcha from an old one and ensures we can use ?. in more places where it previously may have been useful, but could not be used legally due to syntax reasons.

Would be good to link to the repo on the page. Just putting a command on the page to run some shell script is off putting tbh. I imagine that there are people out there that will just run the command without looking through the script (which I assume is the intended scenario). Linking to the sourcecode is more straightforward than making users copy the script URL and paste it somewhere to look at it - I am on mobile btw. (But glad you put the repo here as a comment, otherwise just seemed fishy.)

Interesting, I can also reproduce this. I wonder if it's an artifact of zlib's sliding window setup. The odd part is that if I try various libs with advzip, both the libdeflate and 7z modes show the same artifact, only the zopfli mode is able to avoid it. Doesn't seem to be a format violation as gzip -t doesn't complain about a copy at position 0.

That was the promise with the original Rift, not the Quest. The Quest2 required a Facebook account from day one and never worked with an Oculus account, unlike Quest1. They relaxed the requirement in 2022 to only require a Meta account and converted all old accounts to Meta accounts later on (and if you didn't login to 'ok' that change they deleted your account completely including all the games).

If you created the account early in the Quest2's life, or hit the wrong button in the UI, your Meta account will end up linked to your Facebook account.

You might be able to unlink the Facebook account from your Meta account at https://accountscenter.meta.com/accounts, though I don't know if you can still reach the page.

I was a tech-bro type libertarian dumb ass and my coworkers (even the Pacifica listeners) did not give a fuck. They were all super kind. Celebrated when my kids were born and bought baby clothes. And I was in Santa Cruz with ultra liberal types.

Then I moved to a very red state remote. And none of my co-workers cared until I got a new boss out off Chicago who was excited to have someone on his team that lived in God's country. But for him I wasn't conservative enough (I made a joke about not wanting to use my aerospace degree to make nukes so I switched to software. Guess what he did before software? FML) and I was gone for my wrong think. And I don't think I passed his 'God's country' purity test.

Yes, but with a caveat.

Here in Elbonia H2S costs 5 times the price of Elegoo Centauri.

I know that poor people save money twice, but I think it's also responsible, if you're just treading the water, to get a decent toy and see if that's really something for you.

Recently my gf thought about getting a drawing tablet. Of course I immediately aimed for professional graphic tablet, at least 19". Fortunately we ended up buying cheap Huion [1] and after having a blast with Rebelle for a month it turned out it's not for us. We saved a ton of money in the process and maybe one day I'll decide that the money saved will finance a toy 3D printer. :)

[1] I'm not an artist but I've worked in digital agencies for half of my life and I was blown away by the quality of Huion compared to Wacom. I think it might be similar to some of 3D printers mentioned here.

I sketched and photographed older rock art in high school 50 years past:

The rock art has been dated back to before the ice age ended and is approx. over 40,000 years old and there is up to 1 million rock art images scattered across the entire Burrup Peninsula and Dampier Archipelago.

Oh, it already has taken off sufficiently. There are some 10-20 million users[0]. Like I just said in an adjacent comment I've been using it nearly-exclusively for almost 10 years now, myself. It's not built for "growth" or to "compete" with big corporate social media so it's all good. Whoever is interested can try it out for themselves. BTW I've been on the net since 1992 and can say with certainty, every new social technology is dominated by the fringes of culture at first because we're the ones who want to make our own place that isn't full of jerks. Like, fediverse wasn't taken over by any fringe group, it started on the fringes. We're happy to have anyone who isn't a jerk though, it's generally that simple.

Author here: we do NOT do conservation of energy/momentum. We are currently trying to incorporate that in a follow up paper, but for now, the models that try that (e.g. PINNs (soft constraint) or hard constraint models, all perform bad when modeling multiple systems.

Perhaps, we will encounter the bitter lesson again and a well trained model will solve this. But as I said, we are also looking at hybrid models

I don't really get this obsessive insistence of purging the language of null checks. (And "if(x is not null)" is not an improvement of any kind)

It feels like Microsoft just wants C# to be Python or whatever and the language is losing its value and identity. It's becoming bland, messy, and complicated for all the same reasons they keep increasing padding between UI elements. It's very "me too" and I'm becoming less and less interested in what I used to consider my native language.

I used to write any and all little throwaway programs and utilities in C#, but it just keeps getting more and more fussy. Like Python, or maybe java. Nowadays I reach for C++. It's more complicated, but at least it's stable and not trying to rip itself apart.

Are you having these problems on Element X or Element Classic (the old mobile app, which is in maintenance mode?)

(Element Classic used a mix of legacy Matrix voip calling for 1:1 and Jitsi for group calling; Element X has switched to native MatrixRTC (Element Call) for E2EE for both 1:1 and group, but is technically still beta as we’re still finishing the 1:1 UX. On Android, notifications are a known problem on Element X Android but if you give the app total permission to run in the background they should work.)

For this specific use case, you don’t need anything fancy like a constant time implementation, and I found it easy enough to implement from the paper—except that, mindbogglingly, they didn’t address endianness at all, even though you have to take it into account; so you need to read https://www.spinics.net/lists/arm-kernel/msg633602.html as well.

Look at https://git.chrismorgan.info/tesid/blob/HEAD:/rust/src/fpeck..., it’s very simple.

My PC, my rules.

Everything on my PC is on my terms, and I don't watch ads.

Only when they pay me for the use of my computer equipment and network traffic, do they have any claim to tell me what I must watch on it.

They don't like it, they can feel free to not send me network traffic.

If they really don't want people to watch without ads... surely a tech company of their calibre is capable of blocking content server side, or putting it behind a login.

Forgive me for not feeling morally inadequate compared to a multinational that happily takes ad revenue for toddlers on ipads having their brain fried by endless AI slop that they refuse to moderate.

yeah, FWIU they are an increasingly popular monetization channel in addition to YT's built-in ad-rev system (which is famously very bad for creators)

*) and conveniently for YT that out-of-band monetization channel - which they don't profit from - is the exact thing that's negatively affected by an overall drop in view counts

Yes. I'm a ICPC World Final medalist.

Totally agree that IOI bronze is way easier than ICPC bronze. In terms of rank/ratio, ICPC medals are more like IOI gold.

I stated things like that because I thought it's a bit easier to let people know the difficulty difference. (Agree weirdly though)

FCC threatened Nexstar and all the others that run affiliate networks. Nexstar is trying to merge with Tegna. It's pretty clear how this was a very easy threat for the FCC to make. Without the affiliates ABC has no real audience outside of streaming, and late night shows have already been lagging with ratings. I hate it but really what other option did they have? Disney has never been a company to really fight back unless it was about their bottom line.

Impressive work!

This makes me wonder if Microsoft’s commitment to long-term support is part of the problem: instead of deprecating these ancient APIs they keep them on life-support, but forget some "regression-test" on how they interact with the shiny new surfaces.

Feels like P0’s Windows Registry talks, most of the vulns weren’t in the new code, they were in the how legacy behaviors interacted with newer features.

That "certain period" was over a thousand years. For at least hundreds of years until the about 1900, the region of Palestine was inhabited by the people we now call the Palestinians, not by the ancestors of the Israelis.

> Some who now identify as Palestinian also immigrated during the economically prosperous Mandatory Palestine period.

Relatively few. Not enough to have much of an impact on the overall Arab population of Palestine. This is radically different than the Zionist colonization of Palestine, which was a mass influx of people with the explicit intention of taking over control of the territory.

> Should American families who have only been here for one century have fewer rights

I think you would accept that the following two situations would be very different:

1. People immigrate to the US, settle down, send their kids to school, and eventually become American citizens.

2. A large group of people enter the US with the explicitly stated goal of founding their own country - a country in which they want there to be as few Americans as possible. They have their own militias and operate completely outside the control of any government that the people of the United States control. Just to make this scenario more realistic, we can say that the US is currently under the rule of a foreign empire, so that Americans have no say in their own government. The foreign settlers start taking over large parts of the country. Finally, the UN says that the US should be split in two, giving half of it to the foreign settlers. The foreign settlers agree, but Americans think it's unfair and don't agree. War erupts. The foreign settlers, based on superior political organization and funding from abroad, quickly establish massive military dominance over the Americans, and go on to conquer 78% of the United States, expelling 80% of the American population from the territory they control.

Not exactly the same thing.

My Mercedes has the opposite problem. It will notify me there's an OTA update and ask if I want to do it now, or not. If I just turned the car on, I probably don't want to do it now, so the question is silly. It's unclear if the "Later" option actually applies the update after I've turned the car off, or if it just means it'll nag me again later and the cycle repeats. At least it does map updates automatically.

They are stupid, but also ruthless and willing to ignore the laws they don't like.

They are also surrounded by billionaires that want them to keep it going. Look at how Larry Ellison is buying up Paramount/CBS and soon, Tiktok. They just took Kimmel off the air.

Again, I know this sounds like histrionics on my part but what is happening now is not normal -- the fact that all "old school" republicans have left the GOP and it is now literally the Party of Trump. And they have millions of cult members who are itching to use their second amendment rights against "non-Americans".

I desperately want to be wrong, and would love credible evidence that could demonstrate this.

Facebook made a very expensive new Batman game in VR, there's also Resident Evil, Assassin's Creed, a ton of other high budget games like Red Matter.

It just isn't taking off. In my experience even though VR is unique and amazing, it's not that much better than playing those games flat screen. I tend to spend most of my time in Beat Saber.

I was cancelling my annual slack premium last month and had to click to acknowledge that some of my members are using the AI features and they will lose access to them.

They then offered me a discount and if I refused there was another checkbox where I accepted that I was about to cause disruption for other staff.

I think we are seeing one of the downsides of vertical integration: the team running part of the stack can shit the bed without consequences because they're carried by the whole.

Apple's software design and quality has been going downhill for a while - but their hardware is fantastic and keeps getting better. I've been putting up with the software because the hardware is worth it, and I guess that's going to be put to the test.

For all the griping, it matters little in the face of money. People won't be replaced until sales suffer.

Old Microvision Nomad units from around 2004 pop up on eBay from time to time. I have one; it's a monocular red laser retinal projection display, with a permanently attached computing unit running an ancient version of Windows CE. It's bulky, finicky, and nowhere near open source; there's hardly any documentation for it, but it does work somewhat. I haven't done anything interesting with it yet, because it doesn't have a IMU, and integrating one with it has been difficult.

Microsoft Hololens 2 also used Microvision-derived laser retinal projection technology. I don't have one, so I can't say how well it really works, but Microsoft seems to have given up on it as well.

If you relax your requirements and allow for a green holographic waveguide display, there are a few other options, but still nothing open source that I'm aware of.

I have heard people on both ends of the spectrum:

- LLM's are too limited in capabilities and make too many mistakes - We're still in the DOS era of LLM's

I'm leaning more towards the the 2nd, but in either case pandora's box has been opened and you can already see the effects of the direction our civilization is moving towards with this technology.

This is something I see in newbie or extremely lazy code. You have some nested object without a sane constructor and you have to conditionally construct a list three levels down.

This is a fantastic way to make such nasty behavior easier.

And agreed on the question mark fatigue. This happened to a project in my last job. Because nullable types were disabled, everything had question marks because you can't just wish away null values. So we all became blind and several nullref exceptions persisted for far too long.

I'm not convinced this is any better.

Nick Wellnhofer is stepping away from libxml2 after a decade of unpaid maintenance. He’s forking it under the AGPL, but that will probably scare off most corporate users.

Meanwhile libxml2 is still everywhere. Without someone with real backing, a core piece of infrastructure is about to go unmaintained.

Once again, the open-source funding problem is laid bare: the internet runs on the unpaid evenings of a few people until they burn out (add relevant reference from XKCD, obviously).

I can't shake the feeling that this ship has sailed and only a few got to get on it while it happened.

And this comes from someone who started with Flash, built actual video editing apps with it, and for the last 25 years build application with "it's not a web app, it's a desktop app that lives in a browser" attitude [1].

Even with Flash we often used hybrid approach where you had two builds from same codebase - a lite version running in the browser and an optional desktop app (AIR) with full functionality. ShareObjects and LocalConnection made this approach extremely feasible as both instances were aware of each other and you could move data and objects between them in real time.

The premise is great, but it was never fully realized - sure you have few outliers like Figma, but building a real "desktop app" in a browser comes with a lot of quirks, and the resulting UX is just terrible in most cases.

[1] just to be clear, there's a huge difference between web page and web app ;D

Safety critical fields like aviation already have strict requirements. Usually there's very few software dependencies used in those projects.

Expanding that to more fields would be interesting, but difficult and expensive across the board. Particularly any sort of requirements like that generally incur significant regulatory and certification overhead.

However, if it was done similar to PCISS as an industry forum it might work better. Especially if certain fields like anything connecting with the electric grid we're required to use certified software.

This is so important these days. A lot of project send users to discord, slack for documentation and help but they are not made for this purpose. Searching in chat channel for a specific problem is not a good way to handle documentation. I can't even use search engines to search that.

Have a read about kin selection, for instance. There are lots of facts about e.g social insects (like the male/female/sterile ratio iirc) that were thought to only be explainable by group selection, but later were found to work out purely from considerations of gene selection. I'm just a layperson though, would highly recommend Dawkins writing on this stuff. It's much less polemic than his writing on religion, if that puts you off at all.

I think the basic criticism of group selection is that at an individual level it can be beneficial to go against the group's goal, and you need to explain why that doesn't happen (even very small advantages are rapidly boosted by selection). This is one of the great puzzles of selection - how does cooperation evolve from selfish interests? The theory of group selection just asserts that it does, which is not very satisfactory.
