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!!
