After performing a large number of package upgrades on my Gentoo machine, I discovered that Eclipse would crash when showing documentation, or otherwise embedded browser-base content ( including the web browser preferences) . Continue reading
uvcvideo: Failed to resubmit video URB (-45)
I recently purchased a Logitech Quickcam E3500 for my girlfriend, and attempted to set it up on her Dell laptop running Kubuntu, which initially looked good (simply plugged it in and it worked out-of-the-box as I would expect), however after a few seconds the webcam picture froze, and I noticed a message repeated in dmesg:
uvcvideo: Failed to resubmit video URB (-45)
USB Mounting Problems in KDE
Today I plugged in a USB flash drive (after updating 40 or so packages in Gentoo, including HAL) and received this error in a popup:
mount: wrong fs type, bad option, bad superblock on /dev/sda, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so

Convert Adobe CMYK Images to RGB on Linux
In my job as a Web Application developer, occasionally designers send me images to place on web sites, which is usually fairly simple. However sometimes I receive images from print-orientated designers, who use Adobe Photoshop to create images in CMYK format. These images are great for printing, however they don’t work too well on the web (most browsers won’t even render CMYK formatted colours), so it it’s usually best to convert them.
The GIMP can’t load CMYK images (yet anyway) , and although Krita can open the images fine, changing the colour type usually results in the colours in the image changing. The only way I’ve found to convert the images on Linux is using ImageMagick.
The file or folder … does not exist
I had been having a strange problem with Samba, where creating shares through KDE created shares that are visible through SMB or Windows clients, yet opening them only showed an error that “The file or folder does not exist”.
