Once you learn to ride a bike you never forget. But it turns out you can forget how to ride with SPD pedals…

Click of death

18 Jun, 2014

Old Logitech mice (and other manufacturers too) sometimes develop the “click of death”. Mouse clicks are sometimes not registered, or more common, register as a double click.

This is caused by a worn out micro switch. For my Logitech M505, a Omron D2FC-F-7N, rated for about five million clicks.

New micro switches can be bought on Ebay for about 7 SEK (1 USD) and replacing it is very easy if you have a little experience soldering.

GIMP colour palettes have the file extension .gpl. How cute is that?

Can you see the fnords?

02 Mar, 2014

My new background image is a rip-off of the Boing Boing Fnord t-shirt. Apologies to Rob Beschizza, but your design was too good not to play around with!

IF YOU DON’T SEE THE FNORD IT CAN’T EAT YOU, DON’T SEE THE FNORD, DON’T SEE THE FNORD…

I claim no copyright on this image. TV texture courtesy of Chaotic Resources.

If you dislike amateurishly applied GIMP filters I suggest you check out the unadulterated SVG image.

Personalize your computer

25 Feb, 2014

There are a couple of ways of making your computer really yours. The first is the choosing of a good hostname, preferably something besides “Computer” or your own name. There’s even a helpful RFC for choosing good names!

My systems are all named after characters from the webcomic Sluggy Freelance. So far I have eight systems, fortunately there’s quite a large cast of characters, but I should probably stop collecting computers before I have to resort to using Bert or Doctor Lorna.

The second way to personalize your machine? Stickers obviously!

Bonus shout-outs to Unixstickers for providing nifty Debian keyboard stickers for covering the Windows logo and to camJAMR who sells re-usable webcam covers.

Stripping unnecessary metadata

18 Feb, 2014

Digital cameras add a lot of metadata to photos such as the camera model, settings, date and time and in some cases even the name of the registered user of the camera.

Smartphones may also add geodata, GPS coordinates of where and when a picture was taken.

This is extremely useful but in some cases you might not want to give all that information away. There’s a very handy utility called jhead which makes it a breeze to sanitise JPEG files before publishing them. Simply run:

jhead -purejpg photo.jpg

jhead should be available in most Linux distributions.

Unfortunately, there’s still ways to de-anonymize JPEG images without the Exif metadata.
