ThiloAlright, I am giving this a try.Checking news (i.e. social media) only once in the morning and once in the evening.I made it through yesterday that way, even abstained from the phone on the toilet, and I am moderately proud of myself.It is a bit hard for a <a href="https://mastodontech.de/tags/Scala" class="mention hashtag" rel="nofollow noopener" target="_blank">#Scala</a> programmer, because we frequently wait on builds to complete. <a href="https://xkcd.com/303/" rel="nofollow noopener" translate="no" target="_blank">https://xkcd.com/303/</a> Huge potential for distraction there.

vascorsdIt's impressive how almost always going to the docs page for circe in <a href="https://mastodon.social/tags/scala" class="mention hashtag" rel="nofollow noopener" target="_blank">#scala</a> ends up in frustration. It seems it never tells me what I want and makes me go to a bunch of places to search stuff. All the freaking time. Best option is going to code I have somewhere and try to copy paste.

Boyd Stephen Smith Jr.I want to be your next <a href="https://hachyderm.io/tags/FediHire" class="mention hashtag" rel="nofollow noopener" target="_blank">#FediHire</a> ! I've been a programmer since 1985 (as a child), I've been an IT professional since 1995 (pulling wires and swapping cards and configuring MS Windows). I graduated from University of Arkansas Fayetteville with a BS in CS in December of 2003. A full resume is available.I currently require a 100% remote position. I cannot relocate from Cove, <a href="https://hachyderm.io/tags/Arkansas" class="mention hashtag" rel="nofollow noopener" target="_blank">#Arkansas</a>. I would prefer W-2 employment with a base salary of at least 130k USD/yr, plus some sort of retirement offering (401k or similar) and healthcare benefits (HDCP + HSA or similar).I prefer something where I can be a high-performing individual contributor: reading, writing and improving source text the majority of my day, with some time spent knowledge-sharing with other developers -- learning and teaching. I'd like to work with <a href="https://hachyderm.io/tags/Haskell" class="mention hashtag" rel="nofollow noopener" target="_blank">#Haskell</a>, <a href="https://hachyderm.io/tags/Purescript" class="mention hashtag" rel="nofollow noopener" target="_blank">#Purescript</a>, or <a href="https://hachyderm.io/tags/Idris" class="mention hashtag" rel="nofollow noopener" target="_blank">#Idris</a> as the primary source language.

Daniel DüsentriebOver five years now I'm programming on the JVM. Started out with <a href="https://social.linux.pizza/tags/Java" class="mention hashtag" rel="nofollow noopener" target="_blank">#Java</a>, moved to <a href="https://social.linux.pizza/tags/Kotlin" class="mention hashtag" rel="nofollow noopener" target="_blank">#Kotlin</a> as my daily driver, dipped my toes into <a href="https://social.linux.pizza/tags/Scala" class="mention hashtag" rel="nofollow noopener" target="_blank">#Scala</a> and once in a while enjoy experimenting with <a href="https://social.linux.pizza/tags/Clojure" class="mention hashtag" rel="nofollow noopener" target="_blank">#Clojure</a>. Groovy outside of gradle files, is still a gap to fill.I had the urge to go behind the language and explore the realms of bytecode, linking and loading and JIT compilation and the helpful people on the RockTheJVM discord recommend me this amazing book: "The well Grounded Java Developer" which goes into this step by step. It let me appreciate what an outstanding piece of software the JVM really is. <a href="https://www.manning.com/books/the-well-grounded-java-developer-second-edition" rel="nofollow noopener" translate="no" target="_blank">https://www.manning.com/books/the-well-grounded-java-developer-second-edition</a><a href="https://social.linux.pizza/tags/programming" class="mention hashtag" rel="nofollow noopener" target="_blank">#programming</a> <a href="https://social.linux.pizza/tags/jvm" class="mention hashtag" rel="nofollow noopener" target="_blank">#jvm</a> <a href="https://social.linux.pizza/tags/Java" class="mention hashtag" rel="nofollow noopener" target="_blank">#Java</a>

fanf42So, after more than 2 years on it, we're almost at the point where <a href="https://social.treehouse.systems/tags/rudder" class="mention hashtag" rel="nofollow noopener" target="_blank">#rudder</a> is ported to <a href="https://social.treehouse.systems/tags/scala3" class="mention hashtag" rel="nofollow noopener" target="_blank">#scala3</a> 🎉🎉🎉Rudder is an old beast. 15y old. With lib from that era like (quite fabulous in retrospective) <a href="https://social.treehouse.systems/tags/liftweb" class="mention hashtag" rel="nofollow noopener" target="_blank">#liftweb</a> by <a href="https://mastodon.social/@dpp" class="u-url mention" rel="nofollow noopener" target="_blank">@dpp</a>, XML literals, lib using macro that won't ever be ported to Scala 3, etc.And Rudder has a very peculiar (self imposed) constraint on branch support, where we need to easily switch to and evolve bra ches 2y old, and upmerge changes.And still, with the help of some very talented people, it's happening. With regular update to include syntax changes, prepare the code base, check things run in the future version... Without any impact on the release cycle if the product (until now! Still time to bork everything!)It was an extremely frustrating experience that could have been made easier without the Scala 3.0 big bang but with more iterative small changes like there is in new versions ("the last time syntax will change and books will be written", my ass).But still, the compat layer allowing to use <a href="https://social.treehouse.systems/tags/scala" class="mention hashtag" rel="nofollow noopener" target="_blank">#scala</a> 2 libs in <a href="https://social.treehouse.systems/tags/scaka3" class="mention hashtag" rel="nofollow noopener" target="_blank">#scaka3</a>, and the migration tools, are marvels.
