warpech··on Git 3.0's upcoming SHA-256 default will be a costly mistake
It's Python 2/3 or Node CommonJS/ESM all over again. I thought the lesson of history was that it's more reasonable to live with a known problem (and have mitigations for it) than to "fix" it in a way that breaks everything that's good.
warpech··on Rune is now open source
The business in the service, not the software. Open source increases the vitality of the software through a more engaged community
warpech··on Google will buy half the electricity from one of Finland's nuclear power plants
Build a dam in the fjord and pump the water out from it with excess electricity! Profit
warpech··on Show HN: Foldelight – the iPhone Duo folding effect the MacBook was owed
I don't know either... But it is the first time I've ever seen the parallax effect adding value to a homepage. Great job in that regard!
warpech··on More questions about whether researchers can trust OpenAI with unpublished math
Last year we were saying there must be a human-in-the-loop (HitL), but anyone who is the HitL exhibits the “HitL skill” to the agent.

There might be no books about human intuition but we teach it to LLMs by interacting with them

warpech··on More questions about whether researchers can trust OpenAI with unpublished math
I wonder what’s more valuable in our prompts: the raw data or the feedback system that drives the exchange towards a goal.

For a long time it was clearly the former, but now I think it is the latter.

The models have enough knowledge (orders of magnitude more than a human could ever learn) but are now getting better at what to do with it thanks to learning from the decisions that we make in conversations with AI agents.

warpech··on I tested 10 model/harness combinations on the same Three.js task
What’s a good way to drive models to use current versions?
warpech··on Emacs Bedrock 2.0
Thank you for starting the blog post with reminding what the project is.

So many blogs (and newsletters for that sake) assume the reader knows and remembers what they are about

warpech··on Keep Our Servers Running
Umm, no? The parent means Wayback Machine, which is a service of Internet Archive (both at archive.org). Or am I confused?
warpech··on Google Antigravity TOS: 3rd party usage can get Google account suspended
What is third party? If I self-host OpenClaw, is that third party?

If I write my own harness, is that third party?

Insane policy

Why bother creating a CLI and OAuth interface if your ToS punishes for using it

warpech··on Google Antigravity TOS: 3rd party usage can get Google account suspended
Wouldn’t that violate the quoted ToS? I guess it would.
warpech··on Europe's last regular standard-gauge steam passenger service
Funny that you can buy tickets for this train as a part of the countrywide train network system, but they don’t have a right graphic for this kind of train. The website displays an electric unit with no information that this will be a steam engine: https://koleo.pl/connection/c21a973b-4eaa-55bd-80d0-5dd2541a...
warpech··on 507 Mechanical Movements
I was expecting a new HTTP status code
warpech··on Wi-Fi 8 is the first wireless upgrade in years that isn't chasing speed
That is true everywhere. I think operating systems could do a better job at informing about the health of the internet connection in words the user understands. What seems to be the current bottleneck:

Your router does not respond. Turn it off and on.

This comes close: https://www.getapp.com/all-software/a/breakdown/

Honorable mention - https://postgrest.org/
warpech··on "Solving a largely imaginary user goal"
Thanks, I missed that!

But still, the article continues to ignore that setting, doesn’t it?

The light/dark theme toggle is for a small fraction of the people who genuinely care about controlling the theme to be "right for them" and not just whatever.

warpech··on "Solving a largely imaginary user goal"
Both Marcin and Lea are ignoring users who have automatic sunset-to-sunrise dark theme switching.

This is not a novelty but a built-in feature called “Auto” Appearance in MacOS, iOS, iPadOS. Similar feature exists in Android and KDE.

WebMIDI: https://developer.mozilla.org/en-US/docs/Web/API/Web_MIDI_AP...

It turns state changes from any MIDI device into JS events that you can handle any way you want.

I use Claude Code to wire it up

warpech··on libexpat now funded by the City of Munich for up to 6 months
> The City of Munich follows the principle of Public Money, Public Code: Whenever possible, software developed in-house should be released as open source. The goal is not only to ensure the city’s own IT security but also to enable others to reuse the software securely, transparently, and in a traceable way.[1]

You can control your computer using MIDI interface. Sometimes we demo our JavaScript UI components using AKAI LPD8 MKII

Compiling TypeScript is just stripping out types
warpech··on I learned PCB design, 3D printing and C just to listen to music
That's incredible! I was thinking about such a project but a quick research didn't show any suitable square-shape LCD monitors. I am glad that turned out to me not true.

I will be happy to participate in the Kickstarter campaign

WDYT about adding something more to the screen than record sleeves, e.g., lyrics display?

warpech··on Firefox Containers Preview
What are the cool setups with proxies?
warpech··on Have you restarted your computer this week?
I have a recurring daily task of closing all browser tabs and a weekly task of rebooting my Mac.

Tracking this as a task helps my digital hygiene, and at the same prevents me from doing it more often than needed.

warpech··on Godot will no longer accept AI-authored code contributions
Totally! The feeling of using AI to create something not fully productive is similar to the "just one more turn..." effect when playing a Civilization game. Even when you realize it's a waste, it's hard to stop, because the next dopamine hit is just around the corner.

Tailnet and Magic DNS make it easy to bring other people or devices to your network, including simple authentication mechanisms to know who is who

Cool!

Your readme mentions Modify. What’s that?

Does this use some generative UI?
