Started using plannotator and really happy with it so far. if you're working with AI-generated plans, worth giving it a try. plannotator.ai
Plannotator - Plan & Code Review for AI Coding Agents
Free, open-source plugin for Claude Code, OpenCode, Codex, and Pi. Review agent plans before they execute, annotate agent-written code, send structured feedback back — all locally.

"Tests are no longer even remotely optional" (c) Simon Willison If anything, AI-assisted development made me more strict about testing, not less. AI can generate 200 lines in seconds. Without tests, you have no idea if any of it actually works — and neither does the AI. No excuses. Write the tests.
I'm not vibe coding. I review every line. But even then, a simple "let's reflect" at the end of the session surfaced better rules, docs, and agent configs I'd have missed. The reflection habit matters regardless of how much you trust the AI. Do you do this? 👇
I wish I could acquire skills as quickly as Claude can :) youtu.be/CEvIs9y1uog?...

Programming a programming language sounds odd, we’re used to programming with one, not building it. But after watching this, I must say working on @kotlinlang.org must be pretty cool. In the end, you’re building a product exclusively for devs… and now for AI agents 🙂. youtu.be/ZggUn2mNqMU?...

I wrote a piece for the trivago Tech Blog about how mob programming can turn a team into… well, an actual team. If you're into collaboration, dev culture, or just curious:
Mob Programming: Smells Like Team Spirit · trivago tech blog
Mob programming often sparks hot takes. “It’s counter‑productive.” “One person could do it faster.” “Why waste five people on one keyboard?” If that’s what it looks like in your head—one senior ...

Meta Quest Store saw 12% faster loads & 2.5× faster interactions with #React Compiler. ESLint and React violations looks solid too I'm skeptical, but definitely going to try it out. Auto-memoization without manual useMemo/useCallback sounds promising. react.dev/blog/2025/10...

In the age of #AI and AI-powered IDEs, we should get used to asking questions like: 👉 “Is there a function that already does this?” 👉 “Which part of the code handles that?” 👉 “Did I just duplicate something?”
I was excited to discover #Redis numbered databases… only to learn the same day they are widely considered a mistake. I wonder if anyone is actually using them in production
Out of curiosity, I ran some offline LLMs on my Raspberry Pi 4. Building from source was fun, and watching it struggle to squeeze out a word per second, even with the smallest models, was oddly satisfying. It met my low expectations perfectly 😄 #raspberrypi #llm
Just watched @gergely.pragmaticengineer.com’s “Software engineering with LLMs in 2025: reality check.” Clear, grounded look at how AI-coding tools are used day-to-day. Loved the four wrap-up questions! youtu.be/EO3_qN_Ynsk #llm #ai

🌀 Tried Kotlin Notebook’s `ANIMATE {}` today and got totally sucked in. First plan: shiny data plots. Actual result: a roaming kaomoji ( ͡~ ‿ ͡~) Bottom line: with a bit of code, #kotlin notebooks move more than just data.
3 years in a row, I attended @kotlinconf.com, always inspired by the quality and the community. This year, I had the privilege of speaking there myself. 🎥 www.youtube.com/watch?v=434W... Also happy that I got to bring deltaration.com to the spotlight 😊 #ai #boardgames #kotlin

It does not seem this way when adding bools, but when an extra value has to be added to boolean, I want to go back in time
Most of the time, boolean props on react components are a bad idea. They don't evolve well. More boolean props create impossible states and the component becomes a "thing" that does way too much. Go for string literal union types and slot props (composition) more often than not.
A quick reminder. We all know not to click links on emails from unknown sources. Spam is an unknown source. The "unsubscribe" link is a link from an unknown source. Even a "known" sender can be spoofed. Just send it to Spam (or at least thoroughly vet the URL before clicking). Just sayin'.
Had an inspiring two-day exchange with the #trivago tech crew in the Netherlands! 🚀 Huge thanks for letting me join the lineup. Special thanks to everyone who packed the room for “Mob Programming: Smells Like Team Spirit.” 🙌🔥 Your questions and hallway chats were the best part.
I picked up a Dell in October 2022, installed Ubuntu 22.04 on it, and, surprise! The built-in camera was a no-show 📷. After some digging, I found a workaround and moved on. 1/8
Always wanted to build a personal website but never found the time. Gave #Junie by @jetbrains.com a try, and I’m genuinely impressed with what I could put together so quickly. If it wasn't for Junie, my domain would still be collecting dust: kurets.dev

I don't get it. If it came as a surprise to the managers, then who did this?! Is someone hiding the truth or does it really happen out of the blue, without any consideration as a top down decision?

Spent 30 minutes debugging CSS for my daughter's kindergarten WordPress site… only to realize I forgot a semicolon on the previous line. IDEs make us too relaxed, but honestly, I wouldn’t have it any other way!
