How do I use it in my normal flow?

Edit: the readme on github explains quite well

Yes you can, and this is still the most realistic use of AI llms, but this is a 2x multiplier, not 10x or 20x

Because the vibe coded stuff is sometimes great, sometimes it breaks stuff, sometimes it breaks things that we fixed multiple times earlier. The PRs are too large, nobody can review that mess and you better be on call for your deployment. Maybe it will get better, maybe not. I dont know yet.

Happened to me at least three times the past 14 days. I point out where it made a design decision that causes data loss. «Oops my mistake»

New comment by javier2 in "Idempotency is easy until the second request is different"

i dont disagree with the problem, but this sort of Idempotency-Key header is kind of outsourcing the de-duplication to the client. If the client sends a different request with same Idempotency-Key header its the user's (client's) fault. Its also circumventing the fact that its the effect that should apply to give the same state, you could design the API itself to be idempotent wrt to some other property such as the transaction id. The designs I have seen using an explicit Idempotency-Key header has usually been added on after launch.

advertisers often get their own tracking code running on the site, or at least a handshake (tracking pixel) that lets the ad companies track your traversal on nearly every site.

Did not work in Firefox on Linux, but it runs on Chrome.

Have to admit, I dont get it. I tried it with 3 landscape photos I have and the results were nowhere close to the results in the demo, but that just speaks to the model.

Regardless, its very cool as a browser tech showcase.

Used 13 Minis were exorbitantly priced here. 450USD for a '85%'+ battery and a new iphone 16 was 1000

Well, the research is sometimes 10x quicker with AI assistant. But not always. Building phase is maybe 20-100% quicker for me at least, depending on the complexity of the project. Green field without 15 years of legacy that is never allowed to break is many times faster, always has been.

I have no idea, but my impression was that basically nobody wanted to put in work on X11 anymore.

I have used quite a bit of Gtk and QT, and have had to touch X11 or Wayland very little directly, EXCEPT for one case where I wanted to provide a global hotkey...

we are not as complicated as the national grid, I have been here for nearly 10 years now, and our outages have gone from single cause, two causes, or now its nearly always 3 things that need to go wrong at the same time.

New comment by javier2 in "How kernel anti-cheats work"

javier2 — Sun, 15 Mar 2026 11:30:36 +0000

In CS2, a huge portion of cheaters can be identified just by the single stat 'time-to-damage'. Cheaters will often be 100ms faster to react than even the fastest pros. Not all cheaters use their advantage in this way, but simply always make perfect choices because they have more information than their opponents.

Im just worried many will give them less of a chance to learn, in the same way we were given.
