The Nix Repl is goated. That’s it. That’s the tweet.

So Sonnet 4.5 is a downgrade when it comes to making buckets in Blender, even with the new screenshot viewer feature.

The iPhone 17 pro max sim slot is identical to the 15 pro max one, except the bottom bit is inverted. So you can’t interchange them, but you can plug one into the other 90% of the way.

Broke 10k multi-core score on geekbench on my phone!

Why are these sort of errors so common on Windows? I'm so glad I only use it for gaming.

We had printers before screens. Now we’ve got folding 8K OLEDs… but my printer still refuses to print a PDF without a ritual.

So that was a lie

So it’s 2025 and I am defragging my drives. Why? Well, I’m on btrfs and because of CoW and the nature of the files I store there, everything tends towards chaos over time. This wouldn’t be an issue with SSDs, but I cannot afford replacing my NAS drives with those just yet.

Funny how Americans call it physics, but maths is too far of an ask.

I'm very proud of coming up with this meme.

Apparently you can have biblically accurate eyes? gitlab.freedesktop.org/xorg/app/xey...

You use gpt O3 I use gcc -O3 We are not the same

Oh man, don’t you love USB-C?

So @vscode.dev has this new homepage. You can see in the background some binary, so I couldn't help but inspect the page, and yeah, the whole binary isn't repeated at random. It's all written in CSS. So I decoded it to ASCII, and it says: HAPPY_CODING!

Tried GPT-OSS locally on my RTX 4080 after work today. Tool calling: rough. Lots of errors and loops. Reasoning in chat mode: pretty solid. Even wrote working C code (with some hand-holding). Mixed results, but interesting to see what runs locally now. blog.tymscar.com/posts/gptoss

I was watching the Lex Fridman and DHH podcast and was surprised that neither knew of any other language that can do `5.times` like Ruby. Smalltalk is 20 years older and can do something very similar. Kotlin and Swift can do it exactly like Ruby thanks to extension functions.

Yeah, sleep is great, but have you ever garbage collected 56 gigs in Nix?

So I found some shsh2 blobs I saved around seven years ago for my iPhone 7+ and using Turdus Merula I fully downgraded to iOS 12.1.4 and also jailbroke the phone. Memories are flooding me.

I asked 15 different LLMs from the cheapest to the most expensive one, at the same time, to guess a number between 1 and 50. 14/15 picked 27, and Opus picked 23...

Just shipped a new post on running Docker containers with secrets on NixOS! 🐳 Finally moved my homelab from #Proxmox to pure #Nix using Agenix for secret management. Everything's declarative, everything's public on GitHub, and the tokens stay encrypted. blog.tymscar.com/posts/nixosd...

Tried the prompt in "The Illusion of Thinking" in #o3pro. Only added "no tool use and return the whole result array" The result is 480 moves long, not 1023 as it says(and should be). It's also wrong along the way Don't listen to yt-ers saying the paper is false Try it yourself!

What the hell did my homelab minipc do at 12pm?? 

Is the opposite of a life pro tip an anti death scam?

Do you get cookie-doughella if you eat raw salmon?

Oh man, Java is 30 now! Applets were what wasm is now. Runescape was my main usecase as a kid! #Java30WithIntelliJIDEA www.jetbrains.com/lp/java-30/a...

Dijkstra wrote the best takedown of vibe coding OVER FOUR DECADES AGO: www.cs.utexas.edu/~EWD/transcr...

Lambda calculus bros be like: yo that's so true

Seriously Mozilla.ai: The fuck? The whole project is a bit of a mess but this meme is so tone deaf, such a slap in the face. In a time where people feel corporations abusing all data they can find it is a special kind of brain worm to claim: "Yeah, we also believe that."

It’s only called a sandwich if it comes from Sandwich, UK

Thanks Kotlin. Nice one!

Im curious now @profanity.accountant

look at my balls! 😮

The landing page for my new course features a hidden synthesizer, and that synth has a hidden “randomizer” button! Turns out, you can make some pretty cool experimental music by holding a single note and spamming that button. 😮 🎵 Audio on for this one plz:

Claude 3.7 came out. Tried the question no ai managed to answer correctly to date and it also failed. I don't want to leak it but its something very easy, related to reverse proxies, that you can look up in the docs in a couple of minutes.

When I say no cap I mean I have no capex 😮‍💨

Humans have been programming for centuries, but only recently we experienced programming in its purest form: computer programming. It's akin to the invention of numbers - the separation of the amount of objects from the objects themselves.

Manual transmission is just a leaky abstraction

Tfw Discord is down but when you go check their status page, that is also down.

having your debug renderer also be an OBJ-exporter is nice because i can "draw" random debugging crap in the middle of any unit test, without the need to set up a graphics context. example - debugging frustum splits for shadow cascades.

In fairness, “you can make millions of individual molecules but there are 13 that you need but can’t make so let’s outsource their production to plants. Also, it’s actually 12…you can make one of the vitamins…as long as the sun’s rays touch your skin like you yourself are a plant” does sound fake.

We are entering a Golden Age of grift.

showing off what's inside

I'm fully aware that this is a total waste of my time, but I wrote a blog post about this anyway: simonwillison.net/2025/Jan/2/t...

Every time I go to bed early, I feel tired the next day, even if I do it consistently for months. However, as soon as the holidays arrive and I can go to bed late again, I feel refreshed and energized throughout the day. Perhaps I am indeed a night owl after all! 🦉

🌟 #AdventOfCode 2024 Completed! 🌟 Thrilled to achieve 50 stars again! Used #Kotlin to align with my work, making the puzzles even more enjoyable. Loved the Dijkstra challenges, though I missed the cellular automata puzzles. Thank you for all the work @ericwastl.bsky.social and the team!

The 2024 Unofficial #AdventOfCode Survey results have been published! 🎄⭐️⭐️🎉😊 Available at: jeroenheijmans.github.io/advent-of-co... Some highlights: C++ taking 3rd place, JavaScript dropping behind Java, Neovim further chipping away at vim, and a ton of wholesomeness in the "Other..." answers! <3
