1/ I made slidev-polls: self-hosted live audience polling for @sli.dev decks. Drop a PollResults component on a slide; advance to it; audience joins from a phone, votes, results animate live on the slide in your deck's theme. No tab-switching. github.com/asm0dey/slidev-polls
GitHub - asm0dey/slidev-polls: Live audience polling for Slidev presentations. One container ships the API, voter page, admin UI, and a Slidev addon that renders results on-slide.

CyberJAR crossed 100,000 views on YouTube. 🥳 For us, that is more than a number. It means people keep coming back for practical #Java content from @asm0dey.site and @edelveis.dev, and that means a lot. Thank you for watching, sharing, and helping the channel grow: www.youtube.com/@cbrjar

Day 11 of #AdventOfCode was way easier than the day 10! Because of 2 reasons: 1. I already knew which lib I needed for graph processing 2. A very similar task was solved on day 7 The visualisation is nice tho! asm0dey.github.io/aoc-2025/day...

Pasha Finkelshteyn 🇩🇪⬅️🇷🇺(✡️)@asm0dey.site · 8mo agoWOW, the day 10 of #AdventOfCode was CRAZY. I would never solve it without AI. It didn't generate any code for me, but for part 2, I really needed at least an idea of the approach. And even having it, I would not write it myself - had to use a new amazing library: ojalgo www.ojalgo.org

Day 9 of #AdventOfCode was more complex than previous days. I should admit, I had to use jawa.awt Polygon to solve it (and it's the first time I used it in my life!) However, the solution itself is very simple when you know the ALGORITHM

Pasha Finkelshteyn 🇩🇪⬅️🇷🇺(✡️)@asm0dey.site · 8mo agoThe solution for day 8 of #AdventOfCode is also simple, I would even say straightforward. But I spent an enormous amount of time debugging the first part, where I couldn't get the correct result even for the test input. Visualisation is nice and dynamic tho! asm0dey.github.io/aoc-2025/day...

@jbaru.ch, @asm0dey.site, sending good energy for the talk ahead! Old Java still runs Needs tests, fast speed, and safe design Through runtime it flows #Devoxx #Akka #room7
Still on Java 8 or 11? You’re not alone. Tomorrow at #Devoxx Belgium, @asm0dey.site (#BellSoft) and @jbaru.ch (@TuxCare) show how to make legacy #Java feel better – cleaner code, safer apps, faster runtime, without forced rewrites. 📅 Thu, Oct 9 • 13:50 • Room 7
And @jonatan-ivanov.bsky.social! I would even say Jonathan and me :)

“Microservices will fix it.” Not always. @asm0dey.site explains why most apps run better as modular monoliths with Spring Modulith: clearer structure, safer tests, and less complexity. youtu.be/AkXkEIc8hw0 Curious to hear your view – microservices or monolith?
