In the Meson build system's test harness, a single Ctrl-C terminates the longest running test with a SIGTERM; while three Ctrl-C in a second interrupt the whole run as if you sent the harness a SIGTERM. This was done because it'

That's mostly for historical reasons. Nobody felt the need to switch and do all the work needed to avoid breaking edge cases. GCC used to have Bison grammars but it switched to recursive descent about 20 years ago. The C++ grammar was

How does this approach compare to Dolphin's ubershader?

Almost—even if you need to rebuild dependencies, you can still patch security issues just once instead of doing so in every vendored copy. That's the first point in the parent comment. The same applies to Go.

Yes, I guess it would be an idea. We could also participate to Season of Docs.

If there are parts that specifically you'd want to have better documentation for, please let me know here. Generally we've been moving command line towards a scheme where each option describes an aspect of either the guest (a devi

Documentation is not great I admit. The problem is that we don't have anyone who is a capable tech writer in the team. It's not something that you can improvise. However, all incompatible changes are documented and also announced

Fixed size instructions are not absolutely necessary, but keeping them naturally aligned is just better even if that means using C instructions a bit less often. It's especially messy that 32-bit instructions can span a page.

Nice trick, in fact with 4 instructions it's as efficient as extract/insert and it works for all ADD/SUB/OR/XOR/CMP instructions (not for AND), except if the source is a high-byte register. However it's no

The difference is that you're asking it to perform one intellectual task (write a program) instead of 100 menial tasks (parse a file). To the LLM the two are the same level of complexity, so performing less work means less possibility

Rust Result is basically a checked exception. Java makes you choose between adding an exception to "throws" or catching it, Rust makes you choose between declaring your function as returning Result or checking if you got an Err. T

Isn't that exactly what a USB-C docking station does? It receives display and audio data, and acts as a USB device (keyboard, mouse, webcam). You'd need hardware that can receive DisplayPort, but it's doable.

Props for calling it source available and not hiding behind "you can't police the meaning of open source", though.

The book is good but it has a couple important drawbacks: * while it tells you how to do lock-free programming but doesn't teach you why, nor whether you should it. * it has a relatively narrow focus on linearizability, but the truth i

In the not-a-book section I'm going to plug my series of six articles on LWN.net: https://lwn.net/Articles/844224/ Most of the content is not too specific to Linux, much like this book is not too specific to

Pascal is pretty small and m^3 is pretty large though. That's why we still often use millibar and liter. They just happen to largely cancel out.

But it's a coincidence, right? N*k=8.31 is pressure*volume/temperature for a mole of gas. Temperature has a relatively small range (100-1000) and there's no reason why the range of P*V couldn't be far from that range, fo

That makes no sense. They've internalized the theory so much that they can focus on the magic, and each of them has their own kind of magic, but they absolutely know the theory.

I guess you could use figured bass notation. It's more complex than modern chord notation because it tells you which inversion to use, and it notates secondary dominants (e.g. V of V, which you'd write simply as D7 in jazz notati

Toxic by Britney Spears is basically built on secondary dominants and tritone substitutions (i-VI7-II7-V7 becomes i-IIIb7-II7-IIb7), so they definitely have their place in pop music too. Whether the composers thought about it that way, we c

I would consider Rust to be informed enough by C, that it can be considered a descendent—as much as D, and more so than C# (which is more of a Java-descendent; and while Java's syntax is based on C, that's where it ends).

"Aid" is a bit of an understatement considering that Castro was fighting against the US-and mafia-backed dictator (Fulgencio Batista). The withdrawal of American support to Batista happened because the corruption and violence had
