It's worth pointing out that Cyan made 6 Myst games (not counting remakes), and people only really talk about the first two. That gives you some idea of the staying power of the fr…

AFAIK, sandsifter did find a halt-and-catch-fire instruction on one of the CPUs, but I haven't seen anyone announce which CPU model it was.

Honestly, my first thought watching this video is "I want a root beer float." Something in the way the icefalls as the iceberg is flipping over just makes me think of that...

No, ABI is not part of the C++ standard, although there are parts of C++ that do go "this is an ABI thing" (e.g., [[no_unique_address]]). ABI is more of OS-level thing. Most system…

Cut that graph to the last decade, and they don't look like they've been getting better.

One of the reaction threads I saw elsewhere on social media pointed out the response rates for the surveys that come up with these numbers is plummeting--about a decade ago, we had…

That's true of most of the applications in SPECint (SPECfp is a different matter); there's nothing special about compilers there. Where compiler code is going to get really unusual…

The four benchmarks selected are cppcheck, llvm, cpython, and gcc [1]. These are all essentially compiler benchmarks... and all of the compiler benchmarks in SPEC cpu2026! This mak…

> is there any civilization close to the achievements of the Aztecs and other Amerindians in Africa south of Egypt? Mali? Great Zimbabwe?

I recall opening up the Itanium manual, and by the end of the architecture description, just despairing of the thought of trying to write a compiler for it. Itanium, I think, was u…

While the pop-culture notion of the Dunning-Kruger Effect is "idiots don't know they're idiots," the actual results of the paper were (essentially) that F students thought they wer…

In LLVM, the result of floating-to-int conversion that is out of range of the int is a poison value, which means you get essentially the full unpredictability of UB. That said, I'm…

> Microsoft was forced to respond by making a not-quite-as-bad OS in Windows XP Prior to XP, MS had two lines of Windows: the Windows 9x kernels and the Windows NT kernels. Windows…

Most internet protocols these days have shifted to UTF-8.

All of the major kernel ABIs are using C function interfaces as their stable ABI (except Linux, which uses an assembly syscall instruction as the stable interface, although you sti…

Yeah, the fact that Project Highrise doesn't handle the transportation part of the game means that it never scratched the same itch SimTower did.

Waiting for Don Hopkins to jump into this thread, saying how he's going to release the source code soon... ( https://github.com/YootTowerManagement/YootTower if you haven't seen on…

The best summary--and easiest to remember, IMHO--is that variables are declared as they are used. Want to write an array of function pointers that return a pointer to an array of p…

LLVM defined its AI policy several months ago: https://llvm.org/docs/AIToolPolicy.html (There's already some consternation that it's too permissive.)

My gut reaction is that the probable cause of the discrepancy is ultimately "someone calculated something wrong." It's not like particle physics experiments actually generate somet…

I suspect that they believe they can integrate with a substantial portion of not just the US economy, but also most of the European and formal Latin America economies. And I also s…

The fundamental idea of a jury, when it comes down to it, is that you're asking 12 random people "was this person's actions reasonable?" given conflicting accounts of what those ac…

Since so many people are doubting you here, here is a post from ~a year ago that's pulling the same "LLMs 6 months ago were crap, now they're awesome" shtick: https://fly.io/blog/y…
