Hotswapping allows to exchange byte code while the program still is running. Using the tutorial of Apache Felix as template, this post eloberates on the hotswapping behaviour of this OSGi standard’s implementation.
Surprisingly well Subversion servers can be used also for implementing incremental backup strategies. As it incorporates a good difference handling algorithm and provides magnificant support on investigating versions, it automatically provides features which are ahead of any standard backup program. This post explains how I got to that view and describes the scenario in which it is in productive use.
Apache Felix is an implementation of the OSGi standard. It features a tutorial which I had a more detailed view on.
