“Choose Boring Technology”
I entirely agree if you want to actually ship. Learning takes a back seat. For me, the boring, reliable, predictable tech is #Scala + FP (mostly Typelevel, Lightbend, SoftwareMill stuff) and PostgreSQL 🤷♂️
Well, I did something.
Written some ramblings about #scala and the syntax/way to write typeclasses.
Just the start. Basically notes to myself, but maybe useful for others eventually.
I should turn this into some blog post or put it into a personal wiki or wtv. But ain't nobody got time for that.
So just a bunch of code, hosted in codeberg (gotta start using it more), with a bunch of comments intended to be read from top to bottom.
That's all folks

In general the official #scala API docs are very very lacking and generally suck.
Methods have barely any description on them. There are no examples in most methods to understand them. Important methods and collections lack explanation of their characteristics related to performance, runtime, O notations of each etc. Barely describe where each is more appropriate vs others, etc.

I was pointed out yesterday to scodec for #scala. It has some important things there that seem very useful and will likely use it.
It's just pretty sad that such a known, useful, stable library has most of the site with incomplete docs, broken links and incomplete released version numbers.
Example:
- incomplete docs: from this on scodec.org/guide/Collections.h…
- scodec.org/api/ scodec-protocols 1.2.0 link broken; versions on the page are not latest and you need to check github

Martin Odersky's thoughts on "Lean Scala"

Lean Scala
Program code is for communicating between humans, not just for instructing computers. So we strive for code to be lean. Lean code is simple and understandable. It is as concise as possible without losing clarity.Martin Odersky (Language and Code)

Apache Pekko has left the incubator phase and is now a top-level project.
lists.apache.org/thread/grl5h0…
That's great news! Pekko was created as a Fork of Akka 2.6, right after Lightbend chose to pull a bait-and-switch by relicensing Akka to a non-FOSS license.
I have already switched to Pekko a few months ago, it went very smooth, and I am grateful to everybody involved in making this happen.

Since other people are discussing these things, always a good reminder that on #scala using cats-effect library and using #FunctionalProgramming these thing are properly abstracted away nowadays and on daily usage one finally barely has to care at all about it. - typelevel.org/cats-effect/docs…
