Hacking just for Fun: Raid5 in Java
Hacking . Java . SnippetsI was just curious how easy it might be to write a RAID5 compatible Outputstream in Java? Just a few Lines. For sure it is not the most elegante solution.

Run local/remote terminal commands with java using ssh
Java . Network . Play! Framework . SnippetsSometimes you need to use some CLI-Tools before you want to create or search for a native JNI Binding.

Running a Rails 3 Application in a Sub-URI Enviroment
Hacking . ruby . Ruby on RailsSometimes you need to run your Rails (3) Application on a Sub-URI (e.g. examle.com/prod, example.com/dev). In my current Project there was a Problem with that Configuration and the Rails url-helpers (link_for, url_for, usw.) becourse the app wasn’t aware of the necessary prefix (in our example “/dev”, “/prod”).

Play! Applications und der App-Context
Java . Play! FrameworkEs ist möglich, eine Play!-Anwendung sehr einfach in eine WAR-Struktur zu übertragen und in einen Application-Server zu deployen. Dies ist recht gut unter Deployment options in der Play!-Dokumentation recht gut erklärt. Was hier allerdings verschwiegen wird ist, wie man den notwendigen Context beim Routing konfiguriert. (Der Context ist der Pfad der Anwendung, welcher standardmäßig vom
