Plus, the sbt plugin to reduce Scaladoc size is no longer needed. 🙌<br/><br/><a href="https://github.com/scala/scala3/releases/tag/3.3.9">https://github.com/scala/scala3/releases/tag/3.3.9</a> 2026-10-28T09:55:20Z https://njump.cloud.vinney.xyz/nevent1qqs0r9d9880ute4kd48hq34s4xd76upqy9ahg6zslvlsa9m8qy2an3qzyr6u8avh7a202dx50v979wd0uf3cjnkd457k89zncj4ux86qmvkzxylqwqa Seeing so many security incidents last week made me want to help.

You don&#39;t even need to fear refactoring anymore.<br/><br/>What you really need is a language that catches the AI&#39;s mistakes. You need strong compilers and strict types (like #Rust or #Scala) to act as safety nets when the AI messes up.<br/><br/>This article changed my perspective 👇<br/><br/><br/><a href="https://alexn.org/blog/2026/03/05/boring-tech-irrelevant/">https://alexn.org/blog/2026/03/05/boring-tech-irrelevant/</a> 2026-03-09T09:21:20Z
