Installing ubuntu on a lenovo U410

August 24th, 2012 by Melaneum

The other day, I was helping my brother install Ubuntu on his brand new laptop (Lenovo ideapad). Since I’ve installed linux for the first time things have improved quite a bit (that was on a pentium 75 after printing 100 of pages of documentation as at that time, I had only one computer and no Internet). So I wasn’t expecting any surprises.

Load solved!

May 23rd, 2012 by Melaneum

Finally, I solved an issue that had been pestering me for months. Regularly, when casually browsing, my computer would slow down dramatically for 1-2 min before continuing as if nothing happened. That was particularly irritating and I couldn’t fix this until I found a good way to reproduce it. This half broken bugs are the harder to fix because the incentive to sit down and fix it is much weaker than when everything is broken.

Migrating: from Pocket PC to Android

June 9th, 2009 by Melaneum

I don’t usually follow the latest gadgets and tend to skip a few generations of products before getting a new one. That’s what happened recently when I switched from my Pocket PC staring Windows Mobile 2003 to the HTC Dream (aka G1) with Android. That’s a 6 years gap between technologies and involved some workaround to migrate the contact data.

Distributed version control system

March 4th, 2009 by Melaneum

Few months ago, I moved from Toulouse to Singapore. As I continue to play with satellite images, I wanted to keep an access to the OTB repository and still participate to this open source project. It was also a good opportunity to move to a distributed source control system: sometimes, when you’re stranded in a plane/train/meeting, you really wish to have access to a full repository to do some clean work. Also, if the repository is behind a triple firewall with no possible outside access, this is not a really good way to encourage contributions…
