So... what are the good alternatives to yaml? For quite some time I thought toml, but the way you can spread e.g. lists all over the document can also cause some headaches. Dhall i…

If they didn't change it, Playwright uses the aria (accessibility) representation for their MCP agent. It strongly depends on the web page whether or not that yields good results. …

Ok now I want to know. Does Max php code have security issues? Because especially in early straightforward PHP, those were all over the place. I vaguely remember PHP3 just injected…

This is rust, not Java.

Zug does not attempt to solve memory safety. It aims to be a better C

Sorry didnt see this earlier. If you're interested reach out to me (Kosta Welke) on linkedin. Or write me an email, you can find me on Octominds About page.

Hi! Kosta from Octomind here. We built basically this: Let an LLM agent take a look at your web page and generate the playwright code to test it. Running the test is just running t…

Super cool, thank you!

Also note: traffic costs. On Hetzner, it's almost impossible to pay for traffic. Even their tiniest machine has 20 TB outgoing traffic (and unlimited incoming). If you used it up (…

If you look at rust now, I think it's a great example of keeping the _spirit_ but allowing to question just about any specific decision. Funny that the "why not go" still stands, m…

Well here's the take from the Author itself: https://alistair.cockburn.us/hexagonal-architecture/

Cool article on how to abstract things in Rust. I must admit, I usually write the "bad rust application". Total nitpick: For `CreateAuthorError::Duplicate`, I would return a 409 Co…

It was blank for me as well until I reloaded with dev tools open and cache disabled. Figured it was a caching issue but maybe something more weird?

It's really cool that google is investing so heavily in rust. However, the blog post is more of a "starting point" than a "lessons learned" (which I hoped for).

Apple does this during sleep when connected to power, so maybe Microsoft thought it needs that as well?

Disclamer: I work for Octomind. I think the reading is more "It's hard to find a good abstraction in a field that has not settled yet on what a good abstraction is. In that case, y…

If one goroutine uses 2 KiB stack, then 10,000 goroutines use 20,000 KiB, right? Not 20,000 MiB.

My bad. I was not aware on incredibly limited go generics are. I tried to make it work despite all restrictions but gave up here https://go.dev/play/p/XVTuJ--ZLgS

I don’t think the Option presented here is sufficient (it is indeed a “crime”) as you cannot express Some(nil). But you could probably achieve that using go's not-well-known sum ty…

Actually, go generics can do sum types, it’s just not well known or advertised.
