> "alt+cmd m j/k" (media -> vol up/down)

if only keyboards came with built in buttons for adjusting the volume… oh wait. Unless of course you are suffering on a touch bar mac, then I completely understand.

looks interesting, I agree that chat is not always the right interface for agents, and a LLM boosted cli sometimes feels like the right paradigm (especially for dev related tasks).

how would you say this compares to similar tools like google’s dotprompt? https://google.github.io/dotprompt/getting-started/

Oof, off topic but the trains were out of service here for my commute last night so I though from the headline this meant that somehow all trains everywhere just stopped working. Glad to see it’s just some Saas product that’s down

the windows version is playable on macos through wine. Even modern version, I got it running on a m2 mac mini on Macos 15 sequoia

EDIT: this was for HL1 I’m not sure about HL2

so many times I catch myself asking a coding agent e.g “please print the output” and it will update the file with “print (output)”.

Maybe there’s something about not having to context switch between natural language and code just makes it _feel_ easier sometimes

I've found that a 250w incandescent bulb (can be had for ~$10) paired with a 4000 lumen LED produced decent results on a budget. Search for "reptile" or "chicken" lamps, they are usually red. You can feel the HEAT from a 250w light bulb.

The only thing to watch out for is that the lamp base you're using can support the high wattage.

I still don’t know how openAI thought it was a good idea to have a model named "4o" AND a model named "o4", unless the goal was intentional confusion

the author mentions they’re using haiku for the model, but I wonder if the travel query -> place transform could be done with a tiny local model.

But that’s the bitter lesson I guess, unless there’s a reason to go fully local (extreme privacy concerns, offline use, etc) training a custom model just isn’t worth it over using some cloud api offering, even if it is orders of magnitude more compute that _somebody_ is paying for in the end

New comment by jedbrooke in "Light Mode InFFFFFFlation"

jedbrooke — Sun, 18 Jan 2026 00:09:27 +0000

For me there’s something about context that shapes my dark mode vs light mode preference. Code and terminals is dark, documents/web/chat is light. For some reason I can’t stand dark mode slack/discord, but dark mode IDE is preferred.

Also, there’s just something about the graph of “Average brightness of MacOS screenshots over the years” and extrapolating it that tickles my brain. By 2030 MacOS light mode will just be a single white rectangle (with a notch). It reminds me of the “Number of youtube videos on the homepage” blog that extrapolates that by 2030 there will be 0 videos on the homepage.

Thanks for bringing back memories of the Netflix Wii Channel. At the beginning it was on a disk. We used the Netflix wii channel until the day they dropped support. Our Wii long outlived its life as a games console by continuing on as a netflix machine. I still miss using the actual pointer to point at things, it’s just such an intuitive interface for a TV

EDIT: I just looked it up and apparently the wii netflix channel was supported until 2019, so my memory of using it until it went bust were incorrect. We prob used it until around 2012 or so

I wonder if the RGB strip layout has some downsides, and why such a no brainer idea hasn’t been tried before.

If I had to guess it could be something in the manufacturing process is more difficult.

I had to do a double take on the repo author here :)

this tool also looks super useful, I spend so much time at work looking at json logs that this will surely come in handy. It’s the kind of thing I didn’t even know I needed, but now that I saw it it makes perfect sense.

I still miss it. Worse was they didn't just remove the hardware on newer models, but older models that did have the hardware available had the functionality removed overnight by an iOS update. If I recall it was over some licensing/patent dispute. (plus the feature itself was somewhat polarizing, not everyone found it intuitive)

is there a possibility of using local llm endpoints for this?

to be fair minecraft Java edition isn’t exactly known for having great performance. It will run on a potato, but still runs like a potato even on fast hardware.

This is also not mentioning that the by far more popular version of the game (by player count) “Minecraft Bedrock edition” is written in C++ precisely for performance reasons on low end mobile hardware
