Preventing IDE UI freezes is a collab between JetBrains and plugin authors. Marketplace now shows plugin-attributed freeze reports. 1. Enable reporting in plugin.xml 2. Observe Freeze tab on Marketplace 3. Use analyze-freeze skill by @halirutan.bsky.social blog.jetbrains.com/platform/202...

There's no time to rest! While still at the airport, on my way back from Devoxx, I published a blog post about a new JetBrains Marketplace feature we rolled out! UI Freezes reports are now available for JetBrains IDEs plugin developers 👇 blog.jetbrains.com/platform/202...

Before we can continue with CLion and programming the RP2040, we need to make some more tweaks to the ButtonBox design. Thanks to everyone who suffered with me through the FreeCAD session last night :) The parts printed fine and need only minor fixes. www.youtube.com/@halirutan

That was a weird issue. From "let's quickly check what's going on here..." to "hmm, nothing's obviously wrong", to "can you try this and that?", to bringing in the Platform team for an answer and finally circling back and understanding the actual issue.

An IntelliJ SDK plugin with a configurable settings pane that is Split Mode-aware is now clearer. @halirutan.bsky.social and @picimako have a short guide to handle this. TL;DR: If the Settings UI directly modifies the persisted project state, keep the related `Configurable` on the backend.

People asked for an update to the SKILL.md to analyze UI freezes in the IntelliJ Platform. The skill now handles modern IntelliJ freezes more gracefully by adding coroutines and Dispatchers.Default starvation cases, a few new freeze patterns, and better fixes. gist.github.com/halirutan/36...

If your plugin causes UI freezes for users, you need the right diagnostics to investigate and fix them. The easiest way to collect reports is the JetBrains Marketplace error reporter, but today it does not expose the freeze dumps it already collects. Please upvote the issue in the comment!

Many developers care deeply about IDE performance, so we turned an internal post by Konstantin Nisht into a public one. It covers the architecture behind UI freezes in IntelliJ-based IDEs, what it took to move more work off the UI thread, and the results so far. blog.jetbrains.com/platform/202...

IntelliJ Platform Gradle Plugin 2.14.0 is not a casual upgrade. I’m live tonight at 9 PM CEST / 3 PM EDT on Twitch, X, and YouTube to break down the release, the breaking changes, and the features that matter. I’ll also update the Plugin Template to see what the new setup really looks like.

New Key Promoter X release: 90,000 downloads in 8 days. 7.5M overall. With all the AI coding hype, I didn’t expect this much demand for learning shortcuts. Turns out many of us are still writing code and want to get better at it. plugins.jetbrains.com/plugin/9792-...

This is either brilliant or scary: Anthropic accidentally leaked the TS source code of Claude Code (which is closed source). Repos sharing the source are taken down with DMCA. BUT this repo rewrote the code using Python, and so it violates no copyright & cannot be taken down!

Not at all. In fact, I hovered over them the first time ever after reading your post.

Lovely video, especially the filters in OBS for enlarging single views. I have an AmScope with a good cam wich only works with the bloated manufacurer's software. So I created a single view app using Raylib that always shows only the microscope image and nothing else.

After a discussion about how best to get the view of my Siglent oscilloscope into OBS, I didn't want to accept that the browser is the only option. It turns out you can use a WebSocket connection to access the RFB data directly. That means, you can implement an oscilloscope viewer natively :)
