A day on GitLab without a global incident becomes a rarity. Today: all your jobs start with an hour delay! Not to mention their status page acknowledged the problem 6 hours after first symptoms appeared.

Jeśli przespałeś ostatnie kilka lat i dalej uważasz, że GitLab CI ma sens komercyjnie albo dla open source – nie ma, zwłaszcza do integracji z AI ale nawet najprostszych automatyzacji łatwiej (i taniej!) użyć GitHub Actions https://t.co/Rkx3swGN4u

Po regularnym używaniu do pracy z kodem mogę powiedzieć: europejski AI może być dobry, szybki i tani. Mistral Vibe i modele Devstral to ciekawa opcja. https://t.co/cWcHqQ7W9p

"No consistency, no overarching plan. It’s like I'd asked 10 junior-mid developers to work on this codebase, with no Git access, locking them in a room without seeing what the other 9 were doing." https://t.co/dwO3cWg5jU

@gradle Don't use lock files. It's a half-baked feature. The use is complicated. Many problems (like someone changing a version manually and not updating the lockfile) won't cause a build failure, but be silently accepted, affecting final application runtime. Buggy support in Renovate.

So K2 is the default for Kotlin, but this does not mean you should use K2. K2 is officially still a work in progress, and using K2 means IDE won't allow some common refactorings/quick fixes (that work for Java or non-K2 Kotlin). I still keep K2 disabled.

🏔️ With K2 set to become the default Kotlin compiler in @intellijidea 2025.1, we’re taking you behind the scenes of Kotlin compiler development.

Discover how we integrated K2 into the IDE – and the impact it’s already making.

jakarta.annotation i Optional.orElse nie działają z Kotlinem. Warto zabronić ich używania, na przykład używając ArchUnita https://t.co/u3Y6knjhdl #kotlin #archunit #architecturetests

Spring Boot 3.2.7 is the second release in a row that I am unable to use. Has a regression in Spring Data→Hibernate calls. 3.2.6 had broken spring-aop. I have been using Spring Boot for many years, but I don't remember such an awkward situation.
