En aquest post actualitzaré un llistat de recursos que m’interessa recopilar per tal de fer excursions, viatges, aventures, etc…

Coprocess in shell
This article is pending and will talk about coprocesses used in shells.
A coprocess is a process run asynchronously on a shell that has a pipe for stdin, stderr, stdout, etc. attached to the main process. By this way you are able for example to redirect a main process output both to a log and to stdout at the same time.

Trofeu Primavera Vilanova – 1a Regata – Estupendu Team
Avui hem celebrat la primera regata del trofeu primavera obtenint una 3era posició en compensat, després del Meigas i el Travieso. He fet un vídeo de prova… cal millorar aquesta pujada d’spi.
X Regata Ophiusa
El passat 28 d’Abril es va donar la sortida de la X regata Ophiusa. Aquesta regata celebrada anualment per setmana santa té sortida a Sitges i arribada a Formentera.
És una regata molt tècnica on l’entrada de la primavera provoca una inestabilitat atmosfèrica que habitualment fa que hi hagi tot tipus de condicions: des de encalmades, plujes, vents forts, etc.
Aquest any he realitzat la regata per segona vegada amb El X, un IMX 38 de X-Yatchs.

I have nodes of a cluster with the following features:
Dell PowerEdge M600:
– 2 sockets
– 2x Intel Xeon E5410, 4c (Harpetown), UMA with front-side-bus
– 15GiB FB-DIMM DDR2 667Mhz
Dell PowerEdge M605
– 2 sockets
– 2x AMD Opteron 2345, 4c (Barcelona), NUMA
– 32 GiB DDR2 800Mhz
Dell PowerEdge M610
– 2 sockets
– 2x Intel Xeon E5645, 6c (Westmere-EP), NUMA

Here is how I did it: Continue reading
Hello world!
Hello people!
This is my first post here. Until now I had been writing my notes and keeping my information a little bit unorganizated. I had several webpages, notes, links, e-mails, etc. and this webpage will centralize all of these pieces.
On the other hand possibly this fresh WP install will give me the possibility to restart writing my own articles as I did on my old blog in blogspot. The advantatge of publishing here is that this server is entirely under my control, fully backed up periodically, and more things 😉
I will write in Catalan and in English, I expect you like it!!
