i released a new blog post discussing why you are not "left behind" if you do not become an AI-based software development expert right now, but still need to learn AI-based software development. sounds paradoxical? yes, the world sometimes is ;) enjoy if you like ;) www.ufried.com/blog/not_lef...

Hello, friends! After 10(!) years of #AdventOfCode, I've made some changes to preserve my sanity: there will be 12 days of puzzles each December (still starting Dec 1) and there is no longer a global leaderboard. Read more: adventofcode.com/2025/about#f... adventofcode.com/2025/about#f...
also by that definition Bluesky mobile app is slop, which is not far-fetched given the overheat it gives to my phone. Moshidon (Mastodon client), for example, runs like a breeze
readhacker.news/s/6DfYd I propose even more extreme solutions: 1. eradicate JavaScript: replace slop that is sites repackaged as "native" apps with actual native code. Rust is the new C++, Kotlin and Swift will take care of the mobile. reduce JS application to the toy-level like it should be.
