I'm having Claude Code deal with some code that supports ChatGPT and Claude, and it's genuinely upset that the ChatGPT side of the code is more full featured. I'm dying here 🤣🪦

I laughed at an LLM joke today. We've come far.

Decoding foreign restaurant menus to figure out what you're actually going to get is apparently a skill requiring super-super-intelligence.

Just a bit over a year of work with a small but dedicated team, very happy to see it go out into the wild! www.firefox.com/en-US/enterp...

One of my engineers pointed out a race condition in Claude written code. Claude's reaction: "His reading is correct" /uninstall @anthropic.com

Headed to /r/bun for the drama. Was not disappointed.

HN thread: "The state of Linux music players in 2026" Cmd-F "foobar2000" Was not disappointed.

It sure is a change from having to keep redefining intelligence because computers started doing things that we used to claim required intelligence.

Release notes List of merged PRs ... 90. asdf in #5940 ... It's only a key project in a company valued at 1 trillion dollars, folks.

"This dir has a neural network trainer. We increased our dataset size 7x. Adjust the default number of training epochs (1000) to keep training the same duration and adjust the reporting interval accordingly." SOTA models figure out you want 150 epochs, not 143. Only GPT-5 solves the reporting part.

My article about how we won the 2023 and 2024 World Computer Chess Championships is now out. It includes some previously unpublished details about the design and implementation of Stoofvlees II and should be a fun read if you're interested in computer chess. journals.sagepub.com/doi/10.1177/...

I have an open position on my team. Looking for experience with native application development on Windows/Win32 and good C++ skills. Knowledge of macOS/Linux development a plus, as is experience with Rust. Remote work possible in a lot of EU countries + US & Canada. www.mozilla.org/en-US/career...

I was expected the answer to "why is Codex so much slower than Claude Code" to be something related to their models, and maybe it is, but it surely is not helping that Codex runs all the tool calls under x86 emulation.

DeepSeek V3.1 scores 71.6% on aider polyglot, a slight improvement over DeepSeek R1 0528 while being more than 5 times faster. Cost: 0.60 USD for the entire benchmark.

www.neowin.net/news/microso... Firefox already implemented this security feature over 7 years ago: bugzilla.mozilla.org/show_bug.cgi...

We noticed a CPU bug on Raptor Lake because the bounds checking in our Rust zlib implementation was hitting "impossible" bounds checks: github.com/trifectatech... The Oodle devs noticed similar issues in their decompressors and managed to root cause it: fgiesen.wordpress.com/2025/05/21/o...

OH: "Here we see the seething neckbeard in its natural environment" (Warhammer World Championships thread in /r/belgium)

File -> Open is just not something you can expect to work on a modern Linux desktop. github.com/microsoft/vs...

linux folks: just use your distro's package manager! me this morning: 1. <package> is 6 versions out of date, doesn't work 2. add upstream package server 3. oops! was built in a way that doesn't fucking work 4. download their script to do something to add it anyway 5. okay cool it works. i guess.

Different tests generate the exact opposite conclusion, e.g. github.com/lechmazur/co... "Reasoning appears to help. For example, DeepSeek R1 performs better than DeepSeek-V3 and Gemini 2.0 Flash Thinking Exp 01-21 performs better than Gemini 2.0 Flash."

OH: "we have colleagues who are younger than this file"

Ubuntu 24.04 wrecked my LVM+LUKS install upon upgrading from 22.04. After a few days of fighting with it, key tricks were to add "initramfs" flags for all LVM drives to the crypttab and finally "keyscript=decrypt_keyctl" to avoid having the reenter the password. All of this just worked in 22.04 🤷

"The amount of electricity required to train DeepSeek-V3 would power the Bitcoin network for all of 5 minutes." Random claim on an evil site but I'm totally willing to believe this.

National news reporting on the Hegseth gaffe: "US adversaries now know which chat service to attack...Signal may encrypt messages but it is not secure" Time for my daily dose of Gell-Mann amnesia.

"However, C++ bindings have different semantics than value assignment ... only destructed at the end of the enclosing scope, even though the mapping wasn't bound to an identifier." bugzilla.mozilla.org/show_bug.cgi... Because of course C++ didn't have enough footguns yet.

"The exact format of the id string is left unspecified." aka you must return exactly the same thing as Chrome does.

discourse.ubuntu.com/t/carefully-... "Rust may present a steeper learning curve than C in some ways" I wonder how true that actually is for writing/enhancing a production-level core util.

web.git.kernel.org/pub/scm/linu... This is really nice. The old way definitely had issues like limiting a single Firefox process to about 32GB of RAM. And yeah, most of us wouldn't want the browser to take 32GB of RAM, but if you *need* that for some purpose, then it's a silly limitation to have.

"Allow edits from maintainers" is a really nice small feature and we're jealous at not having it.

23 years after the initial release, and 12 years after it has been deprecated, Apple adds support for patent free audio codec.

Cleaning out the local computer history museum, which is to say, my attic. Some of this stuff is so old, it still came with an actual manual. How the hell was 2004 already 21 years ago?!

API hallucinations are definitely one of the worst things when dealing with LLM.

DeepSeek-R1-Distill-LLama-70B scores only 8.4% in the Aider polyglot benchmark: github.com/Aider-AI/aid..., significantly worse than for example Qwen2.5-Coder-32B. Real DeepSeek-R1 scores 56.9%. The distilled models that "you can run at home" are nothing like the real thing, not even close.

For something like astral uv (the Python package manager), what do we prefer? a) sudo snap install astral-uv b) curl -LsSf astral.sh/uv/install.sh | sh c) pip install uv Pros/cons of each method?

Bug 1944784 - Minidump DumperError only contains the letter 'E', 'F', 'N' or 'W' bugzilla.mozilla.org/show_bug.cgi...

DeepSeek was nice while it lasted. In other, totally unrelated news, I have 64GB RAM arriving today and will be having fun aligning RAM stick timings.

Upgraded to Ubuntu 24.04. See all my terminals disappear if an application OOMs. Read github.com/systemd/syst.... Rage at Linux/systemd ecosystem.

The NVIDIA GTX 750 is 10 years old. It's the first NVIDIA GPU I got in a decade and what lead to the whole Leela ➡️ Leela Zero project. I paid 50 EUR for it, second hand. NVIDIA is now suggesting they could, perhaps, wind down support in the future. How's AMD's ROCm support for the Radeon R9 280?

The reactions to this blunder remind me of the people who looked at computer blunders and concluded "computers can't play chess", e.g. timkr.home.xs4all.nl/chess2/honor... It's not because the computer makes a blunder that an 1800 Elo player would avoid, that the computer is <1800 Elo.
