Unreadable tiny names in LibreOffice Calc sheet tabs

Tiny sheet tabs

This issue happens in LibreOffice 4.3 and older with some desktop themes. To solve this, either change your desktop theme or increase the value of GtkScrollbar::slider_width in the file /usr/share/themes/<your_theme>/gtk-2.0/gtkrc. In my case, the line was commented out. Activating it with the default value did the trick.

Having recently added new key bindings to the desktop configuration, I wanted to merge those new lin [...] Display full article

Nuke (remove all traces) of a file in Git history

First note: if you are not alone on the project, consult with your colleagues before doing this. Because we are about to rewrite history and other contributors will be forced to manually rewrite their history too.

Second note: if what you want to remove is sensitive material (e.g. passwords), consider everything compromised. Unless you are 100% sure that absolutely no one has ha [...] Display full article

GNU/Linux: read-only file system error when accessing FAT/FAT32 drive

Sometimes and for no obvious reason, I suddenly cannot write or delete a file located on a removable USB drive using a FAT file system. Having no knowledge about all the magic going on under file system operations, I can just observe that some actions previously done successfully on some drives are no longer possible!

$ rm -r /path/to/some/obsolete/data/*

Install PHP CodeSniffer with PEAR

This article should be useful for other tools than CodeSniffer. To put some context, I installed PEAR some time ago for PHPUnit, before I read that PHPUnit had moved away from PEAR and can now be installed using Composer or a simple PHAR (PHp ARchive) file. I had troubles with the default PEAR configuration and the various steps to add the right folders in the system $PATH, PHP configuration [...] Display full article
