On Debian:
apt-get install php5-xdebug kcachegrind
Having the xdebug module around will already provide better debugging output in case of fatal errors and uncaught exceptions. The output can still be tweaked though:
In /etc/php5/conf.d/xdebug.ini, below the zend_extension line, add the following:
xdebug.var_display_max_children = 512
xdebug.var_display_max_data = 2048
xdebug.var_display_max_depth = 10
For profiling, add:
xdebug.profiler_enable = 1
xdebug.profiler_output_dir = /my/desired/outputdir
The program "foremost" allows you to recover deleted files from vfat filesystems under Linux.
The search is based on file headers, footers and data structures so it works only on some known types.
For example:
apt-get install foremost
foremost vfatimagefile -ooutput
