Planning Poker

"The idea behind Planning Poker is simple. Individual stories are presented for estimation. After a period of discussion, each participant chooses from his own deck the numbered card that represents his estimate of how much work is involved in the story under discussion. All estimates are kept private until each participant has chosen a card. At that time, all estimates are revealed and discussion can begin again."

Common Use-Cases for Merging

"Another common use for svn merge is to roll back a change that has already been committed. Suppose you're working away happily on a working copy of /calc/trunk, and you discover that the change made way back in revision 303, which changed integer.c, is completely wrong. It never should have been committed. You can use svn merge to “undo” the change in your working copy, and then commit the local modification to the repository. All you need to do is to specify a reverse difference:

$ svn merge -r 303:302 http://svn.example.com/repos/calc/trunk
U integer.c

$ svn status
M integer.c

Using FileMerge as a diff command for Subversion

"Apple's Developer Tools for Mac OS X include FileMerge, a graphical tool to compare and merge files. FileMerge can be much handier to use, unfortunately, it doesn't integrate with Subversion easily. It can be opened from the command line with the opendiff command, but its interface differs from that of diff and diff3. It returns immediately (i.e. it forks and does not block) and it expects different arguments. Some wrapper scripts are thus required to call FileMerge from Subversion."
