Linux
I use Linux. The main reasons are stability and ease of use (I love shells !).
Links:
Debian
Debian is really cool, you have access to billions of package one command line away. The very last package I discover is gcc-snapshot:
http://packages.debian.org/unstable/devel/gcc-snapshot
Basically you have access to gcc4.0 (+fortran !!) with no hassle. another cool stuff is that gcj comes with libjawt (jawt.h ...) can't wait to compile VTK using gcj.
gVim
Tip #312: Copy, Cut, and Paste
Zsh
Zsh simply rocks, there absolutely no reason not to switch to zsh from bash since it support all the bash command and is better:
Also read From Bash to Z Shell: Conquering the Command Line
Some usefull zsh command:
Eventhought it should be possible to set zsh to behave like vim with 'set -o vi', I am used to the 'emacs' style command in zsh:
Ctrl+a : Start of line Ctrl+e : End of line Ctrl+l : Clean screen Ctrl+u : Delete anything Ctrl+w : Delete anything on the left side of cursor Ctr+r : Historic search
Ctrl+y : Paste buffer Ctrl+d : delete active character or disconnect if empty line Alt+b / Alt+f : jump from one word to the other Ctrl+Backspace (Ctrl+w) : erase previous work Alt+d : delete next work Alt+t : exhcange current word and next one Alt+c : capitalize current letter, and uncapitalize the next letter, and jump to the end of word Ctrl+t : exchange two letters

Key to the table above.
Y Feature can be done using this shell.
N Feature is not present in the shell.
F Feature can only be done by using the shells function
mechanism.
L The readline library must be linked into the shell to enable
this Feature.
Notes to the table above
1. This feature was not in the orginal version, but has since become
almost standard.
2. This feature is fairly new and so is often not found on many
versions of the shell, it is gradually making its way into
standard distribution.
3. The Vi emulation of this shell is thought by many to be
incomplete.
4. This feature is not standard but unoffical patches exist to
perform this.
5. A version called 'pdksh' is freely available, but does not have
the full functionality of the AT&T version.
6. This can be done via the shells programmable completion mechanism.
7. Only by specifing a file via the ENV environment variable.

Some tricks I always forgot on MacOSX:
ldd -> otools -L
strace/ltrace -> ktrace / kdump

Valgrind
gdb and valgrind
some valgrind 'feature' to gdb an unitialized var you need to use valgrind macro:
From [How to output address of the unitialized value? ]
Your best bet in that case is to inspect the code at the failing location and see if there is an obvious cause, and if not then to try inserting some assertions using the valgrind macros to try and work out what is uninitialised - assertions like this will do it:
assert( !VALGRIND_CHECK_READABLE( &variable, sizeof( variable ) ) );
file open and valgrind
You can track how many files are open when your programm terminates if you use the flag (works only with recent valgrind version):
--track-fds=yes
Another approach is to use:
strace -eopen
GDB
Yet another trick for debugging the destructor of a class: Steps:
nm --defined-only -C vtkEnSight6Reader.o | grep '~'
copy the hexadecimal for those symbol then do
nm --defined-only vtkEnSight6Reader.o | grep 'my_symbol'
then you just need to add a breakpoint on that particular symbol, repeat if more than one destructor.
CMake
Another trick when writting regex in CMake, look at:

It's fairly well describe
