check library dependency for specific applications

If the libraries appear to be correct, then verify that the application is using the correct libraries. For example, to check that the application /usr/X11R6/bin/glxgears is using the NVIDIA libraries, run: % ldd /usr/X11R6/bin/glxgears
linux-gate.so.1 => (0xffffe000)
libGL.so.1 => /usr/lib/libGL.so.1 (0xb7ed3000)
libXp.so.6 => /usr/lib/libXp.so.6 (0xb7eca000)
libXext.so.6 => /usr/lib/libXext.so.6 (0xb7eb9000)
libX11.so.6 => /usr/lib/libX11.so.6 (0xb7dd4000)
libpthread.so.0 => /lib/libpthread.so.0 (0xb7d82000)
libm.so.6 => /lib/libm.so.6 (0xb7d5f000)
libc.so.6 => /lib/libc.so.6 (0xb7c47000)
libGLcore.so.1 => /usr/lib/libGLcore.so.1 (0xb6c2f000)
libnvidia-tls.so.1 => /usr/lib/tls/libnvidia-tls.so.1 (0xb6c2d000)
libdl.so.2 => /lib/libdl.so.2 (0xb6c29000)
/lib/ld-linux.so.2 (0xb7fb2000)
Check the files being used for libGL and libGLcore -- if they are something other than the NVIDIA libraries, then you will need to either remove the libraries that are getting in the way or adjust your ld search path using the LD_LIBRARY_PATH environment variable. You may want to consult the man pages for ldconfig and ldd.

SIGTRAP or SIG32 when remote debugging threads

http://www.cygwin.com/ml/gdb/2004-03/msg00207.html

Program received signal SIG32

Program received signal SIG32 in gdb:

In gdb, issue the following command:
handle SIG32 pass noprint nostop
That will pass the signal (as necessary) to the program but wont print anything and wont stop.

John the Ripper password cracker

Parallel BZIP2 (PBZIP2) : Data Compression Software

BZIP2 is a parallel implementation of the bzip2 block-sorting file compressor that uses pthreads and achieves near-linear speedup on SMP machines. The output of this version is fully compatible with bzip2 v1.0.2 or newer (ie: anything compressed with pbzip2 can be decompressed with bzip2).

PBZIP2 should work on any system that has a pthreads compatible C++ compiler (such as gcc). It has been tested on: Linux, Windows (cygwin & MinGW), Solaris, Tru64/OSF1, HP-UX, and Irix.

setup X window on a machine with built-in VGA and VGA card

some machines have built-in VGA output and would disable it after you insert new VGA card (AGP or PCI). In some cases, when you run sax2 under Suse, you will get blank/black screen due to wrong detection of multiple VGAs. To settup X window correctly with sax2, try these steps:
sax2 -p : list all your VGA cards
sax2 -c 0 -l : configure card 0 with low resolution mode

detailed configuration of sax2 : http://en.opensuse.org/SDB:X_Server_Configuration_with_SaX2_(8.1_or_Higher)
