Random ramblings about some random stuff, and things; but more stuff than things -- all in a mesmerizing and kaleidoscopic soapbox-like flow of words.

That is a record so far

Without any power outage or any other related problem, I believe this is the uptime record for my Linux machines:

14:56:23 up 51 days, 4:56, 2 users, load average: 0.20, 0.19, 0.12

Linux everywhere

I have recently experienced how Linux and Open Source is ubiquitously present in such incredible places. Yesterday we went to visit BSC's Mare Nostrum, a supercomputer set up by UPC, Generalitat de Catalunya, and the Spanish government jointly with IBM. It runs on Linux, as most of the servers one can nowadays buy from IBM.

It is formed of some ~4000 blades, each one being a more or less complete computer in which Linux is "netsufflated" and makesone piece of a big parallelization machine, connected by 2GBps bandwitdh with the other blades.

It is a pretty amazing place: the computer is inside a chapel, which was desacralized beforehand. The chorus of the chapel will be used to held presentations to visitors.

Also, I recently read about the the MIT project to bring the digital world to the children in developing countries. They use Linux and Open Source software as this is a project were the per-computer budget is crucial. The aim is to start shipping $100 rugged-laptops next year. I find this initiatives of great value for bringing opportunities to millions of childs in many countries.

Finally, and even more extreme, these visionary guys in University of Essex who built a mini-helicopter with a web server running on a mini computer under Linux. Phewww!

Political opinions that I may regret to have exposed: Britain's Labour party

I think that Labour Party is by far the best political option for Great Britain today. I'm glad they won 2005 elections, and I'm also glad that they didn't win by an appalling difference, but yet retaining absolute majority.

Compared to the strict closed party-based system in Spain, even when winning the elections by absolute majority, Labour party in Britain will have to negotiate each and every law, each and every step in the next four years not only with the people, but with each and every member of the party. Which is good. Very different from the situation in Spain during the 2000-2004 PP's period.
