Lost space on root partition
I was recently told by my computer that I'd run out of space on my Mandriva root partition. It's a 26GB partition and shouldn't be anywhere near full but still, this is a bit of a critical state to be in so I immediately investigated.
The first step was to see what the damage was, in this case using df -h:
[james@eastlight ~]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda9 26G 26G 51K 100% / /dev/sda5 236M 202M 30M 88% /boot /dev/sda7 332G 311G 4.6G 99% /home /dev/sdb2 363G 277G 68G 81% /backups
As you can see, the root partition was indeed full so I tried to investigate where the large files were:

Recovering lost files on Linux
I have recently had to try and recover a file deleted accidentally on a Linux EXT3 partition. This is more complicated than it is on a file system such as NTFS where commercial and free software can easily recover any file provided that the physical location of the file on the disk hasn't been overwritten.

Powerpoint 'Smoothzoom' technique
For better or worse, Powerpoint is almost a defacto standard amongst people giving presentations today. Unfortunately, Powerpoint is a crude tool and has many shortcomings.

These often end up pixelated or poor quality when there is no need.
Let's consider an example from a recent presentation I gave. It's a schematic image of a man. Here's a close-up of the large head next to a full size image of the small body. You can see that both the large and small images are clear and not pixelated at all.

Linking to PDF files within JabRef
JabRef is a reference manager based upon the BibTeX system and has many useful and powerful features. One of these features is to link any reference to any arbitraty file. This means, for example, that you can click on an icon by each reference and be immediately shown the relevant source file; a very handy feature. The problem is that is is not immediately obvious how to set up the program to detect these files automatically. That is what this article is about.
The PDF icons by each reference load the relevant file
