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

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?

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.

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.

FYI your domain is marked "newly seen" on cloudflare, which results in it being blocked by Ubiquiti Unifi domain filtering.

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.

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.

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.

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...

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.

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.)

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.

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.

> 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.

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...
