I never encountered any encryption/protection of any kind on the II (had 3 bootloaders: a simple memory loader -> a huffman tree decompressor -> another simple memory loader) and e…

Nice :) I did this for my Axe-Fx II and III a long time ago, but I never published any of it for fear of being sued. Really, I just wanted to learn about DSP techniques and that wa…

I just can agree with any interpretation of the article's code that believes programmers should desire silent sign extension when everything about the expression and data types inv…

I think the lack of a real usable emulator for SGIs is holding back any kind of homebrew. I say this as one of the developer's that got SGI Indy emulation working in MAME. Yes, it …

Another amazing piece of gaming and art by an incredible, dedicated community. I'm thoroughly enjoying it so far, and I've still got a long way to go.

Hardware bugs can be found during chip bring-up within the first couple of months back from the fab, but since I've worked in this area I've never actually seen a bug that couldn't…

I haven't made a website of any kind since a C&C: Red Alert fan site somewhere on GeoCities in the late 90s. I work on graphics drivers. They're hard write and even harder to debug…

This is something I heard through the grape vine years ago, but when you're a very large corporation negotiating CPU purchasing contracts in quantities of millions, you can get cus…

Actually, the reason Transmeta CPUs were so slow was that they didn't have an x86 instruction hardware decoder. Every code cache (IIRC it was only 32 MB) miss resulted in a micro-a…

How is anyone just supposed to know that? It's not hard to find vim, but no one says, "You need to be running this extra special vim development branch where people are pushing vim…

You're (they're?) not alone. This mirrors every experience I've had trying to give them a chance. I worry that I'm just speaking another language at this point. EDIT: Just to add c…

Modern x86 implementations don't even do the XOR. It just renames the register to "zero".

I don't know which strains credulity more: 1.) In the 1960s, the Air Force developed a top-secret device power enough to simulate the EMP of a nuclear blast, i.e. some form of Non-…

I don't even know what a clicker game is or why one would be stimulating.

I must not be the target audience for this kind of thing, but I really don't get it. The few times I've opened HN today I've seen this at the top, and the number of points has been…

> The fundamental problem here is that no standardized shader ISA or even bytecode exists, and there is no material incentive for any vendor to create or agree upon one. It's not r…

The BSF/BSR quirk is annoying, but I think there is a reason for it is that they were only thinking about it being used in a loop (or maybe an if) with something like: int mask = s…

If not is there a reasonably similar open source library?

Yeah, I'm sure that's what anyone trying to build some kind of AI startup that's managed to acquire a small handful of A100 or even better H100s thinks too. "Those cards sure were …

This just in - cherry-picked shitty C++ code behaves shittly. Who cares?

I appreciate that HN follows the research, and have wondered if others have had the same experience as me. My mother was diagnosed with Early-Onset Alzheimer's at age 57 in 2013. T…

No, you're not getting it. The reverse engineering itself is obviously extremely difficult work, but it's the work of an individual or at best a small team. Reverse engineering wor…

Actually, I have changed, and I've changed corporate C/C++ MANY times to satisfy compiler upgrades. It is always just shitty code. It's never something insidious. Bugs happen. It p…

Aside from the contrived examples in the paper, the rest are bugs. The kernel exploit was a just a lack of a NULL check; another bug. Bugs are going to happen, and they're going to…
