Since a lot of you (including me) like to compile and try out new software, I have a tip. After installing it, check to see if the binaries are stripped. This saves a lot of disk space, yet many installers don't bother to strip binaries. The only reason not to strip a binary or library is if you are planning on debugging it. Otherwise, it's just wasted space. A good example is Centericq. After the discussion of Centericq on this list, I downloaded and installed it. the binary was over 20 megabytes before stripping, and after, it was 2.2 megabytes! I am going to check out the libraries that it built as well. To see if a program or library is stripped, type "file program" where "program" is the name of the binary. You will get information about it and the last part will either say "stripped" or "not stripped." Hope this little tip is useful to somebody.
