True that. Looking forward to more novel products by developers for developers if the future. And I can only hope they won’t lose their way and sell out as GitHub did…
I think the thing that used to make GitHub so compelling is that it was a product driven by engineers for other engineers

I don't know about you, but I really dislike the aggressive push of AI tools and agents in text editors and IDEs. I don't mind them having AI features, but enabling many of them by default and pushing for some AI subscriptions is quite annoying.
One day being AI-less might become a feature.

Уж не можело, ама май можело... Нека това да е урок за всички, че апатията дава власт на мафията, а действията като протеста снощи дават власт на гражданите.
Надявам се че този протест няма да остане изолирано явление и ще бъде началото на един траен процес за разбиването на модела "Шиши + Боко"!

Едва ли има изненадани тук. Ще отбележа и че когато Шиши и ко гонят различни депутати в последните години поръчково те винаги се съгласяват да се откажат от имунитета си...

"Лицето с имунитет е председателят на парламентарната група на "Величие" Ивелин Михайлов, стана ясно в съдебната зала, но той не е привлечен като обвиняем. Ивелин Михайлов вече заяви, че няма да се откаже от имунитета си, ако му бъде поискан."

ChatGPT’s signature writing style is everywhere now, and I hate it. It reminds me of when we tried mixing all the beverages at the soda fountain in middle school. We didn’t actually create the perfect drink, we just made a cloying monstrosity that lost everything good about its constituent parts.

It's cool to observe how programming languages affect each other. Recently I've learned that `Seq.unfold` in #OCaml was "inspired" by `Seq.unfold` in its sibling F#. It in turn was inspired by `unfoldr` in #Haskell.
And there's also the pretty similar `std::iter::successors` in #Rust to consider...

One of the many joys of using AI for programming is the creation of huge PRs on complex topics that the authors barely understand, but still suggest "because they work". Here's a great example from #OCaml github.com/ocaml/ocaml/...
