CodeRage6 Fourth Day

Marco's Tech Blog – Another day at CodeRage6, but having real work to do I missed most sessions. Good replays are already online, as I was very interested in the series of RTTI sessions by Robert Love, since I think RTTI is the Delphi language revolution of the last few years.  Today Anders will cover DataSnap ...

Precompiled download and source (git) on code.remobjects.com. The most work, really, was finding my way around the Adium APIs; the actual code is laughably trivial.
