Chnorm is a simple command line utility for setting the owner, group, and the mode of given files and directories on a per file/per directory basis, recursively. It is especially useful if you often copy files with brain-dead permissions from filesystems not supporting the Unix permission scheme. It detects executables based on their contents and sets their permissions accordingly.
dumbsvnreview is a very simple frontend for performing code reviews with SVN. The idea is that you set it up with your repositories and your favorite graphical diff tool and specify the last revision of the last code review. It will then list every change since the last review through a Web interface.
