In your DAW world, AES/EBU transport parity bit corrects most single bit errors as well. It’s a testament to the comprehensive handling of the issue that you as a professional do not need to do much thinking about the problem. Point is still that audio bit errors are historically accounted for due to the obvious consequences of a discontinuity. This persists, often with layers of redundancy, despite that they rarely occur. Video bit errors, not so much
I don’t think the modern web was designed for you.
Thanks. Yes it has wireless charging, but without the magnets. So, Qi but not Qi2.

The magnets can probably be set in the cases, like android phones do, but it's definitely not elegant nor as reliable.

Wireless charging without the magnets is a real PITA, the bad press wouldn't be worth it for a brand that relies so much on marketing IMHO.
(author here) Be careful because (ignoring scale for to keep things simple) a transformation T can be decomposed into a translation and rotation, such that T=Rotation * Translation, but that translation is not along the axis of rotation. You probably want to instead interpolate with a screw motion, which is a rotation about an axis along with a translation along that axis (a helical curve; a curve along the outside of a cylinder). The screw motion is what you get when you interpolate with exp(log(T)*t).
The primary problem with Bluetooth is that you can't simultaneously transmit high quality audio and receive high quality audio. There isn't enough bandwidth to do this. Apple kinds of works around it by using the mic of a nearby device, but this is less than ideal.

A new standard would fix this problem by increasing the bandwidth.
The base units of the metric system are often not very ergonomic. Why is a meter so damn big? And why is a gram so damn small? I can barely detect a gram. And a meter is frickin huge, causing people to usually divide it into hundredths of a meter, which you can hardly picture in your mind unless you already know what it looks like, especially arbitrary counts of cm. Metric's only real advantage is that it shares the same radix as our counting system.

What we really need is a new system of units...
Ok but Celsius works wherever you are (adjusting for pressure)
Yes, hence I wrote (axial translation)+(screw rotation) instead of just (translation)+(rotation).
You can also use the full path to the program, enclose it in quotes, or call "unalias ls" to disassociate it for that shell.
Major ones are enough. Linux and Darwin (that is, macOS and GNU userspace, really) differ sufficiently that you need to pay attention or limit yourself to POSIX. E.g. sed and wc burned me a few times with scripts that need to run on both.
Reasons include other apps they're already invested in, other apps that have more features or have better looking design, etc. Some users are also using free versions of other apps, which they say is good enough for their purposes.

I agree about dev velocity being an issue. As a single developer, it's going to take ages before I can compete head to head with these other established apps, who also have good financial backing.

If I want to get customers for my product, I'll have to look for users who are currently not using anything else so that they can invest on mine. I'll probably have to invest quite a bit on paid ads in order to attract these kind of people because they're hard to come across.

Or I can try the 1000 true fans route and try to get ramen profitability. We'll see how it goes.
Eh. Personally I find it refreshing to see a page err on the side of too many links instead of too few. No need to explain addition in any book if you can just link to the best explanation available.

The bigger issue IMO is that the links seem to be automatically-generated, and the generation is a bit sloppy; for example, the "Syd" links should probably link to the sandboxing technology instead of Pink Floyd's original frontman.
The cost is not static over time. As data storage, laws and AI evolve, the cost of having your data stored somewhere will increase significantly. So if you are making a cost evaluation based on the present situation you are incredibly naive.
Thanks to you and GP for a reasoned response. Appropriately taxing the wealthy is 100% something we also need to do and yes, I am skeptical that the current administration will move in that direction. Ditto cuts to the monstrous military industrial complex.

I think I’ll refrain from responding to the more inflammatory replies but what really sounded the financial alarm for me personally was this talk [1] given to the house on February 5th by Arizona rep David Schweikert. He makes a really compelling case about the dire state and future of the government’s financial position. If indeed I have been hoodwinked as other comments seem to think, I am open to being convinced otherwise. But this talk is well documented, and seems like a plea from a man who is desperate to sound the alarm so we can prevent disastrous consequences for millions of people in this country.

Yes precisely, the latter. I know there are techniques to disentangle that kind of thing but neither I nor they had them readily to hand.
I think it's a vuln to think of OSS in terms of 'a community'. It's an abstract thought construct that does not represent reality (though it helps to make sense of it in a rather specific manner)
xz happened because of the absence of community.
It could happen inside this abstract thought of a community as well but here it did not.

xz targeted deb and rpm. The vast majority of what is facing the world.

Nix did not stop it.

I believe this article feeds the possible vuln rather than prevent it.
Easy solution: Laser gun, problem is now solved up to 100 miles away (0.54 milliseconds).

GPT says that 'a car 100 miles away would be far too small to see clearly, even with the best sniper scope. It would likely ... not be visible at all due to the limitations of optics [25x to 35x] and atmospheric interference.'
Engineers Should State the Obvious
“The brain has areas that encode and decode speech”

“They activate before speaking and comprehension at different, but predictable, times”

“We used deep learning but no one currently cares about DL research so we manufactured a link to LLMs”

The problem with brain research using electrodes is patterns of neural activation is too blunt an instrument to map to the specifics of what people want to learn is going on - mostly thanks to the thickness and effectiveness of the blood-brain barrier as an EM shield - and that doesn’t seem to change even with DL, or we’d have seen more breakthroughs. And brain implant tech is still a ways away. And even an implant would only give detailed info about the local area it’s implanted, and the implantation process may damage key bits of tissue and risks altering the region of the brain under test.

This type of research, with electrodes strapped to a person’s head, is kind of like standing in the next room trying to guess the song you can hear through the wall.

Banning TikTok from the U.S. is really just banning them engaging in financial transactions in the U.S. Asking Google or whoever to poison DNS in a country is a whole different technical ball of wax. The two are not comparable. One difference is that ByteDance won't attempt to engage in financial transactions in the U.S. because doing so would create a diplomatic crisis and anyways it's not easy for a company of that size and with that much business to evade sanctions like that. While the pirate will and can just due to their small size and their ability to set up new bank accounts, which is why countries try to block pirates in the network rather than in the financial system, but blocking them in the network is pretty difficult, and blocking them in DNS -DNSSEC be damned- is basically the easiest way.

The person who invented the term says:

- "forget that the code even exists."

- "'Accept All' always"

- "don’t read the diffs anymore"

I suppose we could get into a discussion about descriptivist vs prescriptivist language, but when a term is _this new_ and specifically coined by _one person_, I think using it correctly is more important than using it based on... well, vibes.

Then show me programs that meaningfully improves safety. And compare them to baseline options to demonstrate this. None of these examples improve safety beyond a trivial check on the output which I can also do with a simple prompt.

Show HN: I’ve made a real-time 3D fluid simulation in WebGPU
Hello,

I've deployed a real-time 3D water simulation for browsers. Works on your browsers which support WebGPU.

- demo: https://splash-fluid.netlify.app/

- code: https://github.com/matsuoka-601/Splash

- demo video: https://www.youtube.com/watch?v=9C7DRSdh88g

To my knowledge, this is one of the largest scale fluid simulations for browsers. Around 70,000 particles can be simulated in real-time on my laptop with only an integrated graphics. With a discrete GPU (e.g. RTX 3060 laptop), 180,000 particles can be simulated in real-time.

An algorithm called MLS-MPM (Moving Least Squares Material Point Method) enabled this level of real-time performance in browsers. For real-time rendering of the fluid, a technique called Screen-Space Fluid Rendering is used.

If anyone is looking for a good alternate to NextJS, try looking into Tanstack Start. It's currently Beta but it will probably be the best way to build full stack React apps when it hits 1.0 so it might be worth looking into for future apps.

You just add a plugin into Vite and gain SSR, streaming, server functions, API routes with minimal configuration. You basically just add a ssr.tsx and client.tsx file into your existing TanStack Router application and it becomes full stack with full type safe.

If you want to go back to a React SPA just remove the plugin and config it back to SPA.

I built an app with it recently and it has an amazing DX.

Best part you can literally run it anywhere. It builds for any platform with a single configuration.
These are very likely misleading stats

> Renewable energy sources collectively produced 81% of Denmark's electricity generation in 2022, and are expected to provide 100% of national electric power production from 2030.

This doesn't say anything about how much of Denmark's consumption this covers, only their production

It turns out they import a bunch of their electricity from neighbors

This is a sneaky way to pretend you don't consume fossil fuels
This resonates much more with with than the above PDF that jumps right into the first definition.
Might not be a big chance depending on the project in question, but it's still tons more likely for someone randomly clicking through commits to find a backdoor committed to a git repo than within autogenerated text in a tarball. I click around random commits of random projects I'm interested in every now and then at least. At the very least it changes the attack from "yeah noone's discovering this code change" to "let's hope no random weirdo happens to click into this commit".

A binary blob by itself is harmless, you need something to copy it over from the build env to the final binary. So it's "safe" to ignore binary blobs that you're sure that the build system (which should all be human-written human-readable, and a small portion of the total code in sane projects) never touches.

That said, of course, there's still many options for problematicness - some projects have commit autogenerated code; bootstrapping can bring in a much larger surface area of things that might copy the binary blob; and more.
Vectrex was a home video game console with a vector display. Vector ("calligraphic") displays were a common alternative for high-resolution graphics from the 01950s until about 01990. Evans & Sutherland were among the last vendors standing. I don't think it's accurate to say it didn't take off; it just landed afterwards, like cassette tapes or slide rules.

Advantages of a vector display: you can display a 1024x1024 3-D image on a machine with 16KiB of RAM and less than a MIPS. You get a lot of dynamic range, so you can make some points on the screen extremely bright.

Disadvantages: you can only draw bright lines on a black background; you can't fill areas, though you can come close if you draw a lot of lines. So all your 3-D is sort of wireframey, though you can of course do hidden line removal. Most vector displays got extremely flickery when displaying more than a few thousand lines; the alternative was the Tektronix 4014 bistable storage tube, which didn't flicker at all because it had analog memory for the vector image (and could therefore do CAD over a 2400 baud serial line) but could only be erased by flashing the whole screen green. So you couldn't do animation.

Basically, once digital memory got cheap enough to back your megapixel screen with a megabit framebuffer, and CPUs got fast enough to draw and erase diagonal lines through it in real time, raster displays could be better in every way than vector displays, so vector displays made them obsolete.
> Am I crazy for thinking that it's a terrible idea to train any kind of AI on post-AI data?

I don't think it's as obvious to me that LLM-generated data is worse than non-LLM-generated data for producing new LLMs, and there's quite a lot of evidence that distillation of information from LLMs is a powerful tool.
Or just social media in general. Even Mastodon is full of toxic people. There's probably something about social media style timelines that brings the worst out of people.

We all want the same view of the Internet and the Domain Name System, do we not?

If so then that entails centralized registries and registrars.

Perhaps what you have in mind is that the registries should be published, including incremental updates, "on a blockchain" so that we can all run our own authoritative DNS root, TLD, and ccTLD servers. You don't need a blockchain for this unless you want people to be able to register domainnames without registrars to mediate the registrations.

Disintermediation of domainname registration might be a worthy goal, and it would help people run their own servers if it meant that registries were public (i.e., iterable, including ownership metadata). But you know that's going to be hard for governments to accept that insist on knowing who the domainname owners/operators are. But you don't need this in order to be able to run your own DNS authoritatives to avoid censorship: if they are public (available for download) just download the various TLD zones and serve them to your devices!

Or, if you don't care for us all to have the same view of the Internet, then.. well, I don't think that would be a good thing. You might send me a link that I can't resolve unless you tell me what DNS you're using so I can switch to it, but switching to it might break other things -- in the worst case you we might not even be able to communicate which DNSes to use in order be able to communicate! That would be terrible. So on the whole IMO we just have to have a centralized DNS and we can only hope to defeat the DNS censors by sidestepping the operators' servers that the censors will rely on -- you might as well just use a VPN.

Oh, and of course you know that nation states won't allow operating systems to have DNS censorship bypass functionality pre-installed, so most users won't know how to do it and won't do it.

The capital of South Australia is some distance from the border, even further from the Victorian capital (Melbourne) and is weakly linked compared to EU countries.

In South Australia, the current connection to Victoria allows for just 25 per cent of its maximum demand to imported or exported.

“So what that means for South Australia is we have to be a lot more self reliant. And ultimately, South Australia is the test lab for the whole NEM (National Electricity Market,”

Or exported .. SA actually exports a great deal of peak renewable energy, it over produces in the daylight and uses that to charge a battery farm or to feed to the neighbouring state.

The stats are no more misleading than the GP claim this is in response to, namely "A grid powered almost-fully by nuclear and water is proven feasible by France."

France derives about 70% of its electricity from nuclear energy, due to a long-standing policy based on energy security.

Last year I was also in a Windows 7 rabbit hole. There's lots of ongoing stuff in the community, and even huge driver packs for Ryzen hardware.

The website that led me down that hole was the one from "spacedrone808" [1] who appeared regularly in /r/windows7 mod posts and issue trackers.

There's also the snappy driver installer project [2] which shares a 44GB torrent with all kinds of drivers, from SATA controllers to NIC to GPU. There's also driverpacks which is sometimes down, sometimes not. In the web archive of either of those you can still find the torrent links though.

Oh and there's driveroff [4] which led me down the rabbit hole of Russian hacking communities that backport software to win7, which is amazing to see that there's this isolated modding community on the internet that uses hardcore win7 modded variants, with self-built firewall software, backported hash file databases for antivirus tools etc.

I had a similar experience with the read-only Postgres MCP. Just asked Claude "how can I optimise the performance of my database?" and boom, it checked missing indexes, most used tables, work_mem, etc and gave personalized suggestions that made sense. It even used data provided by the `pg_stat_statements` extension automatically.

As simple as MCP conceptually can be, nothing like that was this simple and efficient before MCPs. It's a truly game-changer.
Replying to myself as I can't edit anymore, but I think payback can also be about cutting off the person from your life, or otherwise making them irrelevant to you. I don't believe this would qualify as revenge, and I think that this is a rather common type of anger payback. It is also rather healthy and effective when the person has a toxic behavior.

Your answer raises sooo many follow up questions that it's hard to know where to start.

But I suppose let's start at the top - What do you mean by Freedom?

Should you be free from community responsibilities? Can you pollute water sources downstream from your collection point? Should you be free to make noise at 2am if that's what you want? Should your freedoms come with social obligations, like taxes? Should you be free to plant your flag, build your house, feed your goat wherever you like?

Do you think freedom for the individual (the US model where you are free to impinge on your neighbor) is better or worse than freedom for the society (the European model, where you are free to live without your neighbor impinging on you)?

Given that a democratic world imposes the view of the majority on the minority, is this really the ultimate form of government? How would you feel as a minority member of this utopia? How would you react if your demographic goes from majority to minority?

If a society voted (as a majority) to euthenase people over 80 (clearly a minority) would that be OK? Would you change you mind when you were 79?

Indeed, can you ever be free in a democratic world? Or would you, by necessity need to suppress your minority self to be one of the majority to keep those freedoms?

If say, the majority voted on your freedom for bodily autonomy, and decided for you what you can and can't do, are you still free?

I ask these questions not with any judgement, but rather for you to explore what you mean by "freedom" and "democracy" and whether these notions can co-exist.
Well, to me this looks like a security issue and since it is tech-related too, it's kind of obvious why it is posted here?
