The only sane way to consume #YouTube is via subscriptions to your favourite channels (bonus points for using an RSS/feed reader). Never let the algorithm drive your consumption of media, as it's not meant to work for your benefit.

Turning off your Watch History on YouTube improves the experience, as their suggestions are hardly based on your interests. Test it:
‣ Clear your history
‣ Only watch a specific genre for 1–2 days
‣ Notice YT insert politics / celeb gossip / rage bait slop in your suggestions.

“Typing speed and boilerplate aren't a problem, writing code being only a small part of my job” says developer that doesn't write any comments, or tests and commits broken code from StackOverflow or GPT.

Generics: in, out, where | Kotlin

Yes, see: kotlinlang.org/docs/generic...

// Scala code sealed trait Either[+L, +R]: // R2 >: R means R2 is a supertype of R; // Scala 3 also allows `R | R2` (untagged unions) def valueOr[R2 >: R](onLeft: L => R2): R2 = this match case Left(l) => onLeft(l) case Right(r) => r

// Kotlin code sealed interface Either<out L, out R> { // ... } // Extension methods required for any methods incompatible with variance inline fun <L, R> Either<L, R>.valueOr(onLeft: (L) -> R): R = when (this) { is Either.Left -> onLeft(value) is Either.Right -> value }

Coming from #Scala — #Kotlin has somewhat odd restrictions in the type system. E.g., while it supports declaration-site variance, it doesn't support any annotations to make incompatible methods sound, so you either go with @/UnsafeVariance, or with extension methods.

Good Scala developers tend to be amazing engineers overall.

This explains (at least in part) why good Scala developers may seem hard to find - there's a lot of competition for them from other ecosystems too.

The backbone of agentic AI, distributed systems, and OSS sustainability Jonas Bonér talks Akka’s evolution, open-source challenges, BSL licensing, and how Akka powers scalable, agentic AI systems.

Some people refer to Jonas as a '𝗹𝗲𝗴𝗲𝗻𝗱'...

In this @rockthejvm.com episode, Jonas Bońer discusses the future of open-source sustainability and how the actor model powers #agenticAI systems.

Pocket is shutting down. If you're looking for a replacement, I recommend Linkding. Search works well, it's easy to self-host, has Internet Archive integration and on the desktop you can save snapshots via the SingleFile browser extension.

Demanding excellence in software development actually saves time — e.g., good design, code practices, unit testing, you need it all.

Shortcuts, due to deadlines or laziness, are compounding the technical debt, leading to slowdown and production incidents that cost far more.

The Internet is making us dumber because we're fed predigested opinions.

People no longer assimilate information, they're just getting other people's opinions, often packaged in simplistic slogans. It's cognitive outsourcing, and the dawn of GenAI is worsening it.

Yesterday, Romania had presidential elections. We were close to fascism, but the moderate pro-EU candidate won. There has been a lot of tension and uncertainty, but around two hours before voting ended, rainbows after the storm happened, as a sign that things will be alright.

Azi votez pentru libertatea de gândire, de vorbire, de mișcare, pentru justiție, pentru o piață liberă, pentru Europa, pentru Occident 🇷🇴🇪🇺

Azi votez împotriva fascismului, a ceaușismului, împotriva imposturii și a ticăloșiei, împotriva prostiei, împotriva invadatorului rus.

And he isn't wrong. All people need purpose, or a shared sense of good and evil, without which you get eugenics, social Darwinism, nihilism. That faith may not need to be Christianity, but Christianity sure is a good start.

And you're declaring Christianity to be hateful and that's not news either.

All people live their life with faith, there's only the question of what that faith is. E.g., liberal values, or the belief that human life is precious and murder is wrong, are faith-based. Really, anything that's not based in empiricism, like all human morality.

That may actually be a good thing. Breakage is different from accretion. Breaking compatibility might be needed for correctness, but I have the opinion that such releases need to coexist in the same codebase with older versions (e.g., different namespace).
