Answer by Sasha O for How would you use a Distributed Version Control System like Mercurial or Bazaar to manage large binary files?

Even though this is not a DVCS, you may want to look at Dropbox. You mostly work with the recent version of each tile but it keeps versioning information for each file so you can get back to the previos version if necessary. They also use binary deltas which may reduce upload/download times. One big advantage of Dropbox is a very natural user interface which […]

Answer by Sasha O for How to parse dynamic JSON fields with GSON?

According to GSON documentation you can do things like: Type mapType = new TypeToken() {}.getType(); // define generic type Map result= gson.fromJson(new InputStreamReader(source), mapType); Or you can try to write custom serializer for your class.

I am not aware of any automatic screen buffering support in Swing.

Answer by Sasha O for Alternatives to deleteOnExit
