A while ago I asked on Stack Overflow how to create an info icon with wxPython. I asked because I needed a way to to explain the options for a radio control in my NodeMCU PyFlasher project. Ultimately the idea was to redirect users to two online resources that explain those options in much greater […]
“How to validate email with PHP” is conceptually part of a bigger problem: accurately validating web forms including emails without sacrificing good UX. I’ll blog about that some other time. This post presents and dissects PHP code to validate email. The explanations and my reasoning should allow you to adjust the code to your needs […]
Eclipse Mars introduce a terribly annoying feature that you can’t even turn off, sigh. If you now scroll up in the console Eclipse automatically activates scroll-lock. Hence, if you just browse the console output scroll-lock will be ON when you’re down browsing and leave the console. How awful is that? The implementation was triggered by […]
Today I was wondering about Docker default container names. They’re cool enough to have caught my attention during the first hour of playing with Docker. furious_heisenberg, agitated_darwin, romantic_curie… who would come up with something like that? Docker default container names When you create a new Docker container and don’t give a custom name (by passing […]
If you want to build custom NodeMCU firmware for the ESP8266 (Wikipedia) I suggest you don’t build it yourself but have it built instead by a configurable online service: http://nodemcu-build.com. All you have to do is define the branch from which to build and the user modules to include and… Hey Presto! there’s your personal […]

Derby may or may not be a good database – I can’t really tell (and I don’t care either). What p*** me off is the developers’ disregard for the open-source community. Let […]
Sometimes it may be desirable or required in order to comply with regulations to link unit tests back to requirements or risks. In that case you’d need to generate a unit test report listing test name, execution date/time, test result, and requirement/risk IDs. To show you what I mean here’s a standard JUnit HTML test […]
It never occurred to me I should write a Java URL shortener service with Dropwizard and Redis. Not because of Dropwizard or Redis, I just didn’t see why I should write a Java URL shortener at all. That is until I read the blog post URL shortener service in 42 lines of code in… Java […]

It only takes few simple steps to release to Maven Central – if you follow the right tutorial. Brief intro In January 2010 Maven Central stopped accepting rsync feeds from projects into their repository. It […]
Intro There are a number of tutorials out there on the Internet that tell you how to do Sencha Touch native packaging for iOS. The subject is also covered pretty well in the Sencha Touch docs. The problem I have with all those resources: they’re either outdated, outright wrong or stop half-way. I don’t need […]
