I do the below. I like to start projects that most of the time will never be anywhere near any completion. Sometimes though, amazingly, I manage to actually complete something. Which is when you can read about it on my blog, oder in meinem Blog auf Deutsch, or when you can review some code.
Visit my blog at blog.timschroeder.net.
I used to write about OS X app development (not anymore). I write about Linux things, hardware, some law and literature. I have been too silent for quite some time now.
I started this blog in 2010 and most of its older content is very probably not relevant anymore today. Still, I wrote it and there it is.
If you're interested in code I write, explore it on github.com/timschroedernet.
Usually, it will be under at least a MIT license, so do with you want (while you follow the license).
I might be able to provide support, but don't count on it.
I used to develop apps for macOS. I don't do anymore, but the apps are still around somehow and I happen to get support requests from time to time. As I don't use a Mac on a daily basis today, I cannot build or support these apps anymore. Consequently, I have removed those apps that were available in the Mac App Store from it. Nevertheless, feel invited to have your own go and build and use the code. You'll need to have a Mac, obviously, Xcode, and the source code from below links. The apps might not build out of the box.
Recent Menu monitors changes happening to files and folders on your Mac in real time, including custom filters and contextual actions.
Recent Menu was available in the Mac App Store for some time, but is now retired. Its source code is available.
Recent Redux monitors changes happening to files and folders on your Mac in real time, including custom filters and contextual actions.
Recent Redux was the first app I developed and published in the then Mac App Store, back in March 2011. It is now retired, but its source code is available.
