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 even though I got pretty far on the III I could se

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 was enough for me.

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 involved is explicitly written to avoid signedness. At t

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 works, but it's too slow and too old to be usable.

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 be worked around. They happen, but they&#x27

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. You have to be a huge nerd about graphics to

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 customizations that aren't possible outside of gigant

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-architectural trap which translated x86 instructions to

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 to the limits!" Yes, it's fragmented, a

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 context seeing other comments, I almost e

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-nuclear Electromagnetic Pulse device that wouldn't

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 higher. I've opened it 3 times, and cli

> 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 really a material incentive issue. GPU instructions a

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 = something; ... for (int index; _bit_scan_forward(&in

Ask HN: Is there an ARM equivalent to Intel XED?

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 expensive, but ethically, I'd rathe

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. The progression was slow at first, but it was a major pr

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 work only provides existence proofs of security issue

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 probably wasn't your intention, but you

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 have unpredictable consequences. What does that have t

What universe are you working in where you think ANY of that is actually true? In the land of reality where I live and work (I work in hardware), I'm not constructing philosophical prose about well-defined systems. This is another

I keep finding myself angry about the recent (some number of years) focus on C and C++'s undefined behavior. I have been writing C and C++ for 27 years, 16 years professionally, and despite all the scary implications, I do not understa

Of course they realize that, because that's not what the article is about. The problem being described is that the distribution of talent/intelligence across the problems civilization is facing is uneven. The author's perspec

It may look like the person in the demo videos is having to step very carefully because they don't feel very stable underfoot, but in actuality they have to pee really badly and they're desperately searching for a bathroom.

But from the pictures, the Maia 100 is also using CoWoS packaging. That will be necessary for any new HBM chip.
