I'm happy to announce the public release of Ruckus, a Racket IDE for iPhone and iPad.

A neat feature of the JVM is that, out of the box, you can send a running JVM process a SIGQUIT signal and it'll dump stack traces for all running threads to stdout.

Following up on the previous post, another thing that's not well-documented when it comes to implementing widgets on iOS is how to share data between the widget and the main app.

I'm currently adding widgets to Podcatcher and one issue I've run into that's not very well documented is how to trigger an App Intent — for example, to start playing a Podcast — from a widget, ensuring that the intent is performed in the app.

I'm currently writing an Apple Watch counterpart app for Podcatcher.

I recently added support for batch inserts to koyo and thought I'd make a quick post about it.

If you listen to podcasts on iOS, chances are you've noticed an issue some apps have when displaying the playing episode's progress in the media center.

About a month ago, I added transcription support to Podcatcher.

Noise packages Racket & Chez Scheme boot files1 for all the platforms it supports.
