Gracana··on V100 SXM2 pinout and NVLink reference
Nice, I did a similar thing with OCP documents and an SXM2 server schematic set I found, but ultimately lost interest in the project after I rented a server with 8x V100s and realized it was kind of crap for LLM inference.
Gracana··on NetBSD adds a new text editor called atto
Who knew a little emacs-like editor would be so controversial.

I think it looks great. Syntax highlighting, multi-buffer, splits, standard emacs commands... For new users in the emacs camp, this seems like a nice editor to include in the base install. Even as a vi user, I'd be pretty happy being stuck with this in a rescue system.

The pipe is metal. You don't print that part.

Gracana··on OpenBSD 8.0 release will have inteldrm/radeondrm/amdgpu drivers from Linux 6.18
TIL, thanks! I wondered if that was the case, but couldn't find a license while clicking around in the code on my phone.

How does GPL code get ported to BSD?
Gracana··on ETH-68: Ethernet Audio Interface for Linux
That's pretty much it. I wouldn't have mentioned it if not for the fact that it's easy to fix and for users it just looks like the site is down, which is not uncommon for small projects posted to HN.

I guess some people thought I liked cloudflare or something... that's definitely not the case.

Gracana··on ETH-68: Ethernet Audio Interface for Linux
Well, it's certainly a dumb situation that I don't like that's created by my employer (and many others with similar setups), but it takes only two clicks to pick a category to make it available to folks behind these firewalls.

I went ahead and chose "blog" because it sounds like it's a blog. Apparently the "newly seen domains" category goes away on its own after 30 days, so that would have fixed itself, though then it would have been "uncategorized" and still blocked.

Gracana··on ETH-68: Ethernet Audio Interface for Linux
FYI your domain is marked "newly seen" on cloudflare, which results in it being blocked by Ubiquiti Unifi domain filtering.

Gracana··on Claude Code’s suggested message feature: I think the real customer is the model
It'd be interesting to see the trace of that session. Depending on how it used its tools, it may never have seen that comment.

The eqbench creative writing "slop profiles" do something similar. https://eqbench.com/creative_writing.html

Click the (i) next to the slop score for any model and it will show other models that are similar in terms of their most commonly used words and phrases.

Gracana··on CS240 AI Cheating Retrospective
The insistence that you must "work alone" and that similarity between submissions will get you flagged would make me really uncomfortable. I think I would be afraid to talk to the TAs lest I get poisoned by their knowledge.
Gracana··on How did AMD Ryzen get 50% faster in two years?
Yeah, I had to go high-end to get one with enough CCDs to make use of the memory channels. I'm curious to know what all-read bandwidth you see when you run intel mlc on your system. My Xeon W5 was doing ~180GB/s after a lot of tuning, which was very disappointing. The Threadripper does ~320GB/s. From what I've heard, Granite Rapids is supposed to have solved the bandwidth problems that ailed Sapphire Rapids, so your numbers ought to be similar.
Gracana··on How did AMD Ryzen get 50% faster in two years?
I wanted to do that, but didn't like any of the PCIe switches / backplanes I found (mostly due to price). Now, it might be worth buying one of these instead of trying to build a fancy PC. https://c-payne.com/products/pcie-gen4-switch-5x-x16-microch...
Gracana··on Z80 REPL (2018)
Wow, somehow I didn't know about this. Now I'm angry, bundling an official Macintosh BASIC on every computer would have been huuuge for young-me.
Gracana··on How did AMD Ryzen get 50% faster in two years?
On the desktop Intel has better memory controllers last time I looked, but it’s not that big a difference. Something in your setup is just broken. Failures will happen with any brand, so I wouldn’t chalk it up to AMD vs Intel… figure out where your problem is and get the faulty part replaced if you can.

I feel you though, regardless of the cause, that is an extremely frustrating place to be.

Gracana··on How did AMD Ryzen get 50% faster in two years?
Zen 5 really is nice. I swapped my RAM from a Xeon W Sapphire Rapids machine into a Threadripper Pro 9000 series machine and I get almost double the memory read performance, plus it's a heck of a lot faster in single and multi core performance, and it runs cooler and quieter. Huge win all around. Aside from the price... (I went from Xeon W5-3435X to TR Pro 9985WX, eep.)
Gracana··on M5 Ultra Mac Studio Review
Interesting, thanks for the link. Hopefully this will all become very relevant for me soon!
Gracana··on I said no and Apple said yes
Because I'm not friends with all 64 players in the lobby.

I don't want kernel level anti-cheat, though. All the games with it have cheaters anyway.

Gracana··on M5 Ultra Mac Studio Review
I'll probably manage with Mac OS well enough, but my linux distro comes out of the box with all the latest OSS tooling I'm familiar with, plus a package manager, and it has linux cgroups and namespaces that power the container technologies we all know and love.

If I switch to Mac OS, I have to sort out a package manager and install all the stuff that's missing, and when it comes to containers... they're just linux VMs. I'd happily cut out the weird proprietary middleman if I could.

Gracana··on M5 Ultra Mac Studio Review
> And why would you need that to run LLMs?

kokonokko1337 already said it was good enough to run LLMs, presumably RunSet isn't saying the source code is needed to run an inference server.

Gracana··on Bend 2 and the Vibe-Coding Trap
I think people responded that way because you strongly implied he was an unserious vibecoder who was just fooling around, and you called him suspicious as fuck.

Your post and the ones that followed are a good example of the contrarian dynamic that dang often talks about. https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...

Gracana··on Open-source AI and open models reading list
I think you would be pleasantly surprised by the content of the linked article.
Gracana··on So you want to use OpenRouter?
The thing they don't show is the one we really need, especially because model providers can skimp on quality (run lower quantization, lower kv cache precision, etc) to improve their pricing and performance. I agree that it's probably too expensive to keep running the benchmark, but we need some way to hold the providers to a certain standard, otherwise every user has to discover the problems on their own.

Haha, yeah, I mostly remember that they exist and then go look up the actual quote.

Gracana··on It took a year to ship WebAssembly in Anubis
I can’t say I really disagree, and as a visitor of the site that’s the solution I would prefer.
Gracana··on It took a year to ship WebAssembly in Anubis
It’s done out of necessity, you can read about why here: https://people.kernel.org/monsieuricon/creepy-crawlies

As a user/reader/viewer I absolutely hate Anubis and usually turn around when I see it pop up (at least on my phone where it takes ages to compute), but with stats like that, I get why a site operator would resort to using it.

Gracana··on Anthropic's ‘watermark’ text adulteration in Claude is a perversion of writing
llama.cpp (but maybe not for reasoning models?) and sillytavern, maybe others... I'm half a country away from my desktop right now so I can't verify much right now.
Gracana··on Claude writing a macOS driver for my obscure HP printer built only for Windows
I had a discussion about this with a friend recently. I was using an LLM with a serial console that it wrote to allow us to share a connection to a Z80 computer running CP/M. I was having trouble with the assembler, it wouldn’t assemble in user 1 of a particular disk, so I asked the LLM for help. It debugged ASM.COM and the BDOS, walked through the source compared to memory dumps, basically banging its head on the wall for an hour or more, until it finally figured out and verified that my disk had a bad block. I never would have put in that much effort to find the root cause of the problem.
