"Growth here isn't a straight line, it is a journey." Constant challenges makes for a more interesting career and that's exactly how many of us have built ours at JetBrains... and stayed for the long run. Including our CEO Kirill Skrygan, hear how he went from junior developer to CEO over 16 years.

The most common way to lose a hackathon? A good project with a confusing pitch. Judges from the JetBrains x Codex Hackathon on how to avoid it: 🎯 Start with the problem, not the tech ✂️ One thing that works beats five that don’t 💻 The demo is the pitch. Show it working, fast 🎉 Have fun. Judges can tell Big thanks to our judges from OpenAI, Nebius, Scarf, and Stateshift for their notes from the judging table.

We asked our team to walk the Loop Lobby and answer a few questions about their work. See what they had to say now.

A prompting technique claims that speaking to AI coding agents in compressed, caveman-style language can reduce output tokens by up to 65%. The JetBrains AI team put it to the test. In 86 agentic coding tasks and roughly 240 trials, caveman-style responses used around 8.5% fewer output tokens, with no detectable drop in task quality. Why so much less than advertised? In coding-agent workflows, most tokens go toward code, diffs, tool calls, and exact error messages. Caveman-style language leaves all of that unchanged. It only shortens the narration between actions, and there is very little to compress, so it is probably not a major cost-saving technique. But there may still be the practical benefits of less narration to read, faster scanning, and a clearer view of what the agent is doing. Read the full analysis: https://jb.gg/3br5o0

One prompt. Thousands of files. A complete interactive 3D experience. Our colleague Mike Hartington asked the latest Claude Opus model to transform a massive node_modules directory into something developers could visually explore. Working inside a JetBrains IDE, the model created the data-processing script, selected an approach for representing the results, and built an interactive Three.js experience where every file and directory could be navigated. The first working version was ready in minutes. What stood out wasn’t just the speed. Using Claude Opus 5.0 inside his IDE let Mike take a broad creative idea, have the model make the architectural and implementation decisions, and rapidly turn it into a functional experience. Try Claude Opus 5.0 in Junie or any JetBrains IDE.

Have you ever wondered what goes into creating a mascot? Turns out, it takes a lot of people and a lot of listening! Kodee, the Kotlin mascot, was shaped by our designers, copyeditors, marketers, researchers, localization specialists, and, of course, the Kotlin community. In this blog post, our Strategic Research team shares how their efforts helped the other teams make sense of community feedback, explore different creative directions, and understand not only what people preferred but also why. Read the story behind Kodee's creation: https://lnkd.in/gQnnNCbF

What if your notebook stayed in sync automatically? marimo is a reactive Python notebook: change one cell, and the cells that depend on it update too. Notebooks are stored as `.py` files, making them easier to version with Git, run as scripts, and turn into apps. It’s available in PyCharm, IntelliJ IDEA, CLion, DataGrip, DataSpell, GoLand, and Rider through an external plugin developed by the marimo team. Try it now: https://lnkd.in/ddWQ8ZFB
