The only bit of Ubiquiti gear I can tolerate is the many years out-of-date EdgeRouter 8 Pro, and only because OpenWrt supports it, and it runs dual-core octeon (2 GB DDR3 which is huge for a router) with decent hardware flow offloading.

tucnak commented on It is worth it to buy the fast CPU   blog.howardjohn.info/post... · Posted by u/ingve

On a different note. I just bought a Sienna-series EPYC, which is a 48-core Zen 4c chip capped at 200W. AMD 8434PN at 1200 EUR price-point. My understanding is it's a two- or three years out-of-date CPU, but I was simply blown away! I contemplated purchasing a 9005-class CPU, but even 32-core variant would cost more than 3000 EUR... at sommat crazy like 400W. Thank you, my PCIe stuff alone draws a kilowatt; no way I'm putting in a 400W CPU on top.

You'd be surprised how low the capacity of a lot of internet links is. 10Gbps is common on smaller networks - let me rephrase that, a small to medium ISP might only have 10Gbps to each of most of their peering partners. Normally, traffic is distributed, going to different places, coming from different places, and each link is partially utilized. But unusual patterns can fill up one specific link.

10Gbps is old technology now and any real ISP can probably afford 40 or 100 - for hundreds of dollars per link. But they're going to deploy that on their most utilized links first, and only if their peering partner can also afford it and exchanges enough traffic to justify it. So the smallest connections are typically going to be 10. (Lower than 10 is too small to justify a point-to-point peering at all).

If you have 10Gbps fiber at home, you could congest one of these links all by yourself.

Now this is Cloudflare talking to aws-east-1, so they should have shitloads of capacity there, probably at least 8x100 or more. But considering that AWS is the kind of environment where you can spin up 800 servers for a few hours to perform a massively parallel task, it's not surprising that someone did eventually create 800Gbps of traffic to the same place, or however much they have. Actually it's surprising it doesn't happen more often. Perhaps that's because AWS charges an arm and a leg for data transfer - 800Gbps is $5-$9 per second.

Hot take. 40 Gbps is not a real rate; it's just four 10 Gbps in a trenchcoat stacked on top of one another!

In case you didn’t notice the parent comment specifically said Baudrillards writing was hard to follow. This channel is run by a philosophy PhD who explains his work. You think he’s misrepresenting baudrillards work I’m guessing?
tucnak · 5 days ago
It's just funny; philosophy YouTube is a simulacrum in its own right. On a different note, I don't think Baudrillard is worth reading in 2025. I would rather recommend Mark Fisher, but then again it's all gravy, baby. To call all this pop literature "philosophy," especially post-Wittgenstein is a bit silly after all.

I would actually recommend the YouTube channel Plastic Pills. This is a great video to start with: https://youtu.be/S96e6TdJlNE?si=gSVzXyyBq7t_q0Xp

Name-dropping Baudrillard based on Youtube videos is real rich... in irony.

I love that.

My happiest professional programming has been C

I often encounter people that want to learn a programming language and ask if they should pick Rust as their first language. My answer is universally: NO.

Learning a first programming language is hard. And Rust will only make it harder since all you're going to do is debug compiler errors all day and never even see your program actually run until it's "perfect". This will be incredibly frustrating and you'll give up.

I always tell people to start with Python, JavaScript, or Lua. You can make something fun and interesting for yourself, like a game, and get immediate feedback and you can iterate quickly.

To be fair, Rust is genuinely just as _hard_ in 10th language capacity.

I know I'm biased, but Rust is the closest thing we have to a perfect programming language. Is the borrow checker a pain in the ass? Yeah. But is it necessary? Absolutely. Imagine writing the same buggy program in C, deploying it, and then it blows up at runtime—you still have to fix it, right? A bug is a bug, and it needs fixing. The difference is Rust forces you to deal with it before you even get a binary, while with C you might get a 3 a.m. wake-up call trying to figure out what went wrong. So it’s not that Rust is harder, it’s just different. It takes a paradigm shift in how we think about writing safe and secure code. Change is uncomfortable in general for humans and that paradigm shift is precisely why most (I hope not) people feel this way about Rust.

You've missed the primary point of the post entirely. Borrow checker per se is not the problem; it's the sheer amount of everything. There's multiple ideas of perfection. Those of us to have very much enjoyed ostensibly imperfect Rust of 2018 find this particular, current flavour unappealing. It may as well be capable tool in deft hand, however, as-is the case with everything in life, you cannot help but ask yourself THE question; is it worth my effort? For me personally, if I were looking for better C/C++ in 2025, I would choose Zig before Rust any day of the week (one exception being Postgres stuff, pgrx ecosystem that is really special!)

But then again, anything beats writing C for a living.

tucnak commented on Weaponizing image scaling against production AI systems   blog.trailofbits.com/2025... · Posted by u/tatersolid
K0nserv · 6 days ago
That's it. The attack is very clever because it abuses how downscaling algorithms work to hide the text from the human operator. Depending on how the system works the "hiding from human operator" step is optional. LLMs fundamentally have no distinction between data and instructions, so as long as you can inject instructions in the data path it's possible to influence their behaviour.

There's an example of this in my bio.

"Ignore all previous instructions" has been DPO'd into oblivion. You need to get tricky, but for all intents and purposes, there isn't really a bulletproof training regiment. On a different note; this is one of those areas where GPT-5 made lots of progress.
