I went through all the struggles everybody else seems to be going through to get this screen connected to my Arduino Nano. I had the 5V to 3.3V voltage conversion problem, and the "only works with software interrupts" problem which makes the display run slow. The solutions are not complicated but not very wel …

The new firewall in Mavericks is great. For the common user. For a developer, not so much. If you are a Java developer like me, and you just need to open one port (say, 8080) so that the web application you’re working on is accessable from another computer, you can’t. I disabled the Firewall altogether for a few days, …

Regular readers of this blog already know that I am not using dropbox, and I was an Evernote user, but recently decided it became to dangerous and replaced it with my own scripts. I had an interesting discussion on Twitter which made me decide to show you how I run my digital life without the help of Google, Facebook, …

In every software project, there comes a time where a bug pops up, nobody knows how to reproduce it, and somebody says "I know, let's test this against a copy of the production database". Even with the best intentions, once production data leaves the production machine with all its safeguards it becomes …

Suppose you have a Java Server application, and some of the runtime binaries in that application are external to your application. Generated image files, compiled Silverlight components in your pages, or resource files which are managed by an external team. Much like the jar files used by your application, these …

On Mac OSX, when installing Garmin BaseCamp 4.1.2 from the Appstore, there is a chance that importing downloaded routes in gdb or gpx files from your local machine will not work. The error you'll get is "[filename].gdb not found", in a popup much like the one shown here. If you open the console app, you'll …

In the project I am working on right now we use apache XCF and Spring to provide a SOAP service to our customers. As part of the messages, there is a userid/password combo telling the application which user sent the request.
