GMail no se cayó, fue un efecto óptico
Wednesday, February 25th, 2009Yo creo que ahora, un día después, es momento de analizar lo sucedido ayer con respecto al servicio de correo proporcionado por google.
El día de ayer a las 10:30 CET, al intentar acceder a través de un navegador web a la dirección http://www.gmail.com se mostraba el siguiente mensaje de error:
Y no solamente en www.gmail.com sino también al intentar acceder al servicio a través de cualquier dominio usando google apps (como en mi caso mail.perseum.com)
Sin embargo, al intentar acceder al servicio a traves de un cliente de correo electrónico, usando POP3, o enviar correo electrónico usando SMTP, el servicio funcionaba perfectamente.
Si a eso añadimos que el servicio Jabber/XMPP se podía seguir utilizando incluso mediante GTalk (en lugar de a través de la interfaz web), la pregunta es: ¿Qué fue realmente lo que se cayó? y… ¿Cómo siendo un sistema distribuido y con balanceo de carga, se pudo caer en todo el mundo al mismo tiempo?
¿Se cayó el servidor web?, No (el mensaje de error seguía mostrándose)
¿Se cayó el de correo? Parece ser que no.
¿El servidor de nombres? Pues tampoco
¿El de Jabber/XMPP? Ni por esas.
Mi conclusión es que realmente no se cayó nada. Todo fue un efecto óptico de Google.
Gmail caído
Tuesday, February 24th, 2009Gmail en este preciso momento se encuentra totalmente caído. Es la primera vez que me pasa desde que lo uso (hace más de 3 años). Al parecer esto incluye también el servicio de mensajería instantánea GTalk. Es probable que sea a nivel mundial, al menos Noruega, España y Grecia han sido afectadas.

Flirting lessons for geeks
Thursday, January 15th, 2009Postdam University (south of Berlin) offers flirting lessons in a course for students of Master in Information Technologies. This is because of the topic which says that geeks have reduced skills for social interactions.
I think those are only nonsenses, the best you can do in order to flirth is to get an elixir that increases charisma +2 and change glasses vision +4 with contact lens vision +2. Changing the hair style can help also with a 0.05% probability. If this doesn’t work you can always overcome the rejection by killing dragons… 
If programming languages were religions…
Wednesday, December 17th, 2008I have just read a post written two days ago (thanks David), comparing the programming languages with the religions.
To say the truth, I found it quite ingenious and I wanted to contribute to the list adding the comparison betweeng Brainf*ck and the religion of the Flying Spaghetti Monster (FSM)
“Then brainf*ck would be like the Flying Spaghetti Monster Religion: brainf*ck is a parody of language in the form of a satirical protest to the simplicity of compilers and complexity of languages”
BAD POOL CALLER: BLUE SCREEN OF DEATH
Friday, November 28th, 2008
Since some time ago I have been suffering a blue screen of death. I would like to know if it only happens to me or there is some one else.

short form or complete form
Monday, October 27th, 2008Due to some work requirements I needed to install LAMP (Linux Apache Mysql y Php) over Windows (some new headache).
I downloaded, installed and configured the last version of every service without problems ( no comparison with sudo apt-get install mysql-server php5-mysql ).
When I try to test if the configuration is working I write a “phpinfo.php” file with the content:
< ? phpinfo() ? >
But when I open the page http://localhost/phpinfo.php I find that it’s completely empty.
So, I started looking into the log and restarting services/os until I think about changing the test code for:
< ? php phpinfo() ? >
which happened to work properly.
The problem was that one of the configuration options of php.ini, short_open_tag (that states if the short form of the opening tag “< ?” can be used instead of the complete form “< ? php” . Until now, this value was true by default, but it has been changed to false, so that the short tag was not recognized by the php module.
The reason for this is to allow the use of other tags starting with “< ?” like ‘< ?xml’ (in fact it’s still possible to use them by < ? echo '< ?xml'; ? >).
The general recommendation is to use always the complete form if it is necessary to have a portable code, because it is quite probable that otherwise, in a future, trying to run the code will not work.
