Perl - Find and replace all

Find cpp and hpp recursively from the current directory then append those files onto the perl command, which substitutes "old" for "new" in those files while creating .bak backups.

find . -name "*.[ch]pp" -type f | xargs perl –i.bak –p –e 's/old/new/g;'

or non recursive:

perl -pi -w -e 's/search/replace/g;' *.php

-e means execute the following line of code.
-i means edit in-place
-w write warnings
-p loop

KDE - Umbrello

I tried out Umbrello for KDE. Seems to work better than MagicDraw at reverse engineering C++ code. It's free. Crashed on a couple of the files I tried though.

Firefox - Reduce RAM when minimized

Move Firefox to your hard drive when you minimize it, taking up less memory. And there is no noticeable difference in speed when you restore Firefox.

• Go to about:config
• Right-click anywhere → New &rarr Boolean
• config.trim_on_minimize
• Set to TRUE
• Restart Firefox for these settings to take effect
