I like the new "group changes" with "AI" feature in IntelliJ version control. If only it was local, then you could run it continuously and get a warning as soon as you start working on more than one thing. This could be a good addition for the Limited WIP plugin 🤨

I wonder why most "AI" tools have such a bad UX and questionable quality? From a sociotechnical system point of view, could this be a reflection of some underlying issues in this space 🤔

I don't know if anyone from JetBrains who works on automated refactorings follows my feed, but I just wanted to mention that a few rounds of Refactoring Golf will reveal gaps.

It's worth reminding a lot of AI folks that:
Time saved by optimizing a non-constraint is not time saved for the whole system. It's not only time not saved, it's actually reducing the throughput of the whole system.

I’m pleased to say that Kodee has recovered from the punch and even got a new friend. #KotlinDevDay25 had the most backend Kotlin developers I’ve seen since Kotlin became a thing on Android 🙈 It was also really nice chatting to people from Xebia, JetBrains and Flock. Thank you for having us!

Apologies for Duncan punching Kodee off the stage at #KotlinDevDay25. I disapprove of this! 😿 You can find the source code from the talk here github.com/dmcg/gilded-.... We were only seconds away from the `::invoke::invoke::invoke` part 🙈

After about a month of experimentation, I'm happy to present a minimalistic test progress bar plugin for IntelliJ IDEs plugins.jetbrains.com/plugin/28859.... Admittedly niche, it's there for 💰 to fund Dark Arts coffee beans, but I'll happily share forever free version(s) with anyone I know or met 😅

If you happen to be in Amsterdam at the end of November, come say "hi" at the Kotlin Dev Day, where Duncan McGregor and I will be doing 47 refactorings in 45 minutes (see kotlindevday.com/program). I will also be just hanging out with Kodee on the 28th, so happy to chat or do a code kata 🧐

Confused as to why my 🇫🇷 and 🇳🇱 Youtube channels all started speaking 🇬🇧 all of a sudden, until I realized Youtube started automatically dubbing all videos.
Thanks, but I can speak several languages, I WANT to listen to other languages. How much compute power is getting wasted with this WTAF?

Thanks to everyone who came to the "47 Refactorings in 45 minutes" talk Kodee and I did at Droidcon London today. You can find all the code here github.com/dmcg/gilded-.... Since someone asked, these are some of the heuristics I use for Kotlin code dmitrykandalov.com/tidy-kotlin.

IntelliJ IDEA includes an open-source Java decompiler called Fernflower.
But did you know that you can use it as a standalone CLI program?
And what's even better – it's now available on Homebrew!
To install it, run the `brew install fernflower` command in the terminal.

In spite of the horrid LLM (aka "AI") bubble hype, it can actually be useful. My favourite use case is asking Junie questions about large code bases. For example, clone the IntelliJ source code, open it as a project (so that Junie can search actual code) and ask questions.

Some quick stats:
We had a total of 59 Kotlin fans attend, including 8 speakers, of which 5 international ones.
Big shout out to Kunlabora, Triple D, DPG Media, PTV Logistics and of course @jetbrains.com for their amazing support.
