Out of curiosity, I did a search through HN from a few years ago, and, just as I expected, people were bringing out that quote to argue against the cryptocurrency skeptics. Of course, the cryptocurrency skeptics were right all along. Anyway

Also relevant, ClueBot NG, which uses ML to automatically revert vandalism: https://en.wikipedia.org/wiki/User:ClueBot_NG This kind of thing is a clear benefit of ML, in my view: there's far too much vandalism on

Yes? A large number of the big ticket bugs, such as win32k lockdown, are now fixed.

This document is fairly out of date, as clicking through the bug links will illustrate.

Not really, except for a few researchy object capability based systems. (This is kind of the promise of ocap systems: functions you call can only use what they're given and nothing more.) If you don't trust a library, you can run

Well, the Apple II had a 280x192 display (53 kpixel), and my current resolution (which is LoDPI!) is 2560x1600 (4 Mpixel). When you phrase it as "in 2024 we can render 76x the pixels with the same speed" it actually sounds rather

I tried to get it to write 6502 assembler for the NES. As I recall it mistakenly thought that there was a BIOS containing a print function.

I tried to get ChatGPT to write LLVM IR last year. The results were interesting: the LLM wrote superficially correct-looking IR, but it ultimately failed to grasp the concept of SSA, as it kept trying to write to SSA registers. ChatGPT can

The benefit of wgpu is that you don't have to mess with synchronization the way you do in Vulkan and DX12. This is an enormous productivity booster. Besides, if you pick one native API (say, Vulkan), then you're still going to go

Last I checked (which was years ago, admittedly) the GLX libraries still required Xlib. There were XCB functions for GLX, but they didn't work with the client-side libraries, so you had to use Xlib. Of course, you should just skip GLX

Whether a hypothetical alternate world in which Rust didn't have a package manager or didn't make sharing code easy would be better or worse than the world we live in isn't an interesting question, because in that world nobod

A court has now determined that nobody was spreading libel in this circumstance.

A U.S. court has now weighed in on that question and has decided that Elon attempted to stifle free speech as the U.S. courts and Constitution has defined it.

This is actually a successful anti-SLAPP motion using California's law, which, if I'm not mistaken, makes X liable for the defendant's legal fees. The order is well worth reading. The judge is clearly having none of it: http

My personal opinion (and I don't speak for anyone else) is that Bevy 0.13 is usable for 2D games if you use Tiled as your editor. Most 3D games will have to wait until 0.14 (the next release) though, since there isn't animation bl

There are a few third-party ones. https://github.com/rewin123/space_editor is the one I use. It's not pretty, but it works well enough. Having an official editor is definitely on the roadmap.

In theory this is what Bundles are for, though it's easy to not realize that there's a bundle for what you want to do. I should note that this is a problem with most game engines, not something unique to Bevy. For example, Unity i

It's a ton of wasted money. We should spend limited resources on treatments that actually work. I feel tremendously for patients and their loved ones frustrated with the FDA's sluggishness, but results like these illustrate why it

Agner says that AAA has latency 5 on Cannon Lake, so using that instruction is a bit faster than doing the operations manually. But if you vectorize (or use SWAR) I imagine you can start to beat the legacy instructions with larger numbers.

A formerly-popular cipher that works better than you'd expect given its extreme simplicity--simple enough that you can encrypt and decrypt it by hand with a deck of cards. Nowadays it's insecure though, so you should never use it.

Windows works just like GNOME here: decorations are client side and are drawn in user32. dll.

Yep. It's a great example of how keeping clean-room reverse engineering legal is good for the industry. While Intel was stuck in Itanium hell, AMD was able to leapfrog them and create x86-64 because it had been legally successful with

Quartz isn't really similar to Display PostScript. Vector drawing is done client-side and isn't proxied out to the window server like NeWS and NeXT did. Sure, you can use Quartz to draw to a PDF, but you can do that in Cairo too.

The design problem has been fixed, as I noted above.

It's been backed up behind a giant rewrite of more or less the entire trait system. This has been an enormous, many-year project that's been years late in shipping. The issue isn't so much the difficulty of the problem as the

Because Rust doesn't have a specification, we can argue back and forth forever about whether something is part of the "language design". The point is that the design problem has been fixed by desugaring to bounds on "for
