Cambios en mi web

Después de postergarlo por mucho tiempo y tras haber adquirido algo de experiencia al crear con Jekyll las web de HackLab Almería y Club de Cacharreo me he animado a descartar al viejo Lameblog y ponerme manos a la obra. Si se nota alguna inconsistencia en mi web tened la seguridad de que es culpa mía. Y no me refiero al diseño, que es algo que ya doy por perdido.

Algo fantástico de Jekyll es que puedes migrar un blog al menos a través del fichero RSS del antiguo. Y por ahora parece funcionar divinamente.

Una inconsistencia a la que tristemente renuncio a corregir son las URI/permalinks originales, que además son las que usa Disqus para recuperar los comentarios. Como Lameblog se hacía algo de lío al generar las URIs con la localización ES pues se ha quedado todo un poco guarro y ahora me parece un lío arreglarlo. Por otro lado voy a procurar a no eliminar contenido de las URIs antiguas por los (pocos) enlaces externos que pudiera haber. Perderé los comentarios, sí, en las versiones nuevas de las entradas pero realmente no son demasiados y deberían seguir accesibles en las antiguas.

PD: Finalmente me he puesto a migrar los comentarios del blog alojados en Disqus. Afortunadamente parece que el proceso está bastante bien implementado Migration console y en mi caso, ya que no me he atrevido a especificar unas reglas que indiquen la transformación de las URIs antiguas a las modernas he seguido el procedimiento manual en el que descargas un fichero CSV con las entradas (URIs) que Disqus ha registrado en la columna A para añadir en la B la nueva. En mi caso han sido más de 500 pero, OjO, 500 URIs no significan 500 comentarios ni por asomo. De hecho una de las cosas que he verificado es el poco interés que despierta mi blog por los pocos comentarios o recomendaciones recibidos :_( En fin.

El caso es que he querido verificar cada una de las URIs si eran dignas de ser migradas y sólo se me ha ocurrido un procedimiento manual que básicamente he gestionado con esta línea de bash:

   for a in `cat olea-2016-08-21T20-27-31.368505-links.csv ` ; do chrome "$a" && read -p  "pulsa Enter" ;done

Donde olea-2016-08-21T20-27-31.368505-links.csv es el fichero CSV descargado. El porqué del read es para evitar que se abran 500 solapas en el navegador.

En la práctica han sido muy pocas las URIs que he indicado migrar (20 o 30 máximo) porque no había más comentarios ni recomendaciones. A continuación, siguiendo las instrucciones de Disqus he subido el fichero CSV revisado y he esperado a que fuera procesado. Y listo.

En realidad me ha costado un poquito más porque ha cambiado el código que Disqus proporciona para integración y al final he encontrado este precioso código jekyll de Joshua Cox que ha terminado por resolver toda esta parte.

Ale, a disfrutarlo con salud.

PS: Igual hasta hacemos otro tallercín en el HackLab Almería para compartir la experiencia con los compis.

Novedades en la equivalencia internacional de títulos superiores españoles

Para empezar reconoceré que no tengo bien estudiada la regulación de las titulaciones universitarias en España. El caso es que he recibido el aviso de que se han publicado por fin las equivalencias internacionales de los títulos españoles. Por algún motivo tradicional, la estructura de las titulaciones superiores en España ha tenido poco que ver con las del resto del mundo. Se supone que ya todos sabemos cuáles han sido las transformaciones obligadas por «el plan Bolonia», que entre otras cosas pretende la movilidad de estudiantes y trabajadores y la interoperabilidad automática de los títulos superiores entre los paises comunitarios (creo que estrictamente va más allá de la UE pero hoy no es mi objetivo ser exhaustivo). Al parecer esa transformación de los títulos no era suficiente para saber cómo equivalen en el extranjero nuestros títulos. Y peor aún, cuáles son las equivalencias de los títulos superiores pre-Bolonia, que con frecuencia siguen siendo un lío al cambiar de universidad sin salir del país. La novedad es que parece que esa información ya ha quedado resuelta.

Siendo muy esquemático: el sistema de interoperabilidad de las titulaciones superiores en España se establece en el Marco Español de Cualificaciones para la Educación Superior (MECES), que, si yo no lo entiendo mal, sirve para establecer las equivalencias con el Marco Europeo de Cualificaciones para el Aprendizaje Permanente (EQF en inglés), que es la piedra de Rosetta para todo este sistema.

Pues bien, desde el 1 de junio de 2016 ya están publicadas oficialmente las equivalencias, como indican en el original: «correspondence between the Spanish Qualifications Framework for Higher Education and the European Qualifications Framework».

Cuadro MECES / EQF de equivalencias de títulos superiores españoles

¿Cuáles son las consecuencias? Probablemente algunas más, pero entiendo que al menos a partir de ahora, por ejemplo, puedes matricularte en cualquier universidad que implemente el EQF sin tener que pasar por el desesperante proceso de convalidación de tus títulos.

Dejo esta entrada a modo de recordatorio personal y con la esperanza de que sea de utilidad. Si alguien detecta algún error que por favor lo indique en los comentarios.

Algunos recursos de investigación sobre calidad del software aplicada a proyectos de software libre

Con la excusa de responder a una solicitud de información sobre este tema he preparado un repaso, informal e incompleto, OjO, de recursos relacionados que tenía en mente. Y ya puestos lo cuelgo en el blog. Aquí está.

Sonic Pi packaged for Fedora

Maybe you know about Sonic Pi, the system to learn programming playing with music. Now I want to give it a try in my system (Fedora 23) and my sysadmin-TOC syndrome obligues me first to package it into RPM. Now I have good and bad news. The good news are I have a testing release of Sonic Pi for Fedora 23. It includes a desktop file too. The bad news are... it doesn't work yet. Sonic Pi uses jackd while a common Fedora Workstation uses pulseaudio and both try to manage the sound device by themselves.

After a quick googling seems possible to get a procedure for using some working configuration for puleaudio+jackd but I didn't have the time to find and check them. Meanwhile, if the RPM package is useful for someone here it is.

This package depends of Supercollider as provided by Planet CCRMA package repository. To use this Sonic Pi maybe you'll want to add the repository to your system.

Please feedback here if you know how to make sound to work.

PD: Post edited to add references to Planet CCRMA repositorie.

Running EPF (Eclipse Process Framework) in Linux

For many time I wanted to learn to use EPF but technical reasons always stoped me. Blame me because I'm not an Eclipse guy and I'm not into its eclipse-isms but until today I have not been able to launch it. Now, wirth this really simple recipe you'll be able to run it.

Initial technical scenario:

Then unzip the file and execute:

$ unzip epf-composer-1.5.1.7-linux.zip
$ cd epf-composer
[epf-composer]$ ./epf
Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /home/olea/epf-composer/plugins/org.eclipse.equinox.launcher.gtk.linux.x86_1.1.2.R36x_v20101019_1345/eclipse_1310.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

(Epf:27092): Gtk-WARNING **: Unable to locate theme engine in module_path: "adwaita",

(Epf:27092): Gtk-WARNING **: Unable to locate theme engine in module_path: "adwaita",
Gtk-Message: Failed to load module "pk-gtk-module"
Gtk-Message: Failed to load module "canberra-gtk-module"


If you, like me, don't know nothing about Eclipse maybe you are doomed because the real problem is everything but clear. What you are having is the EPF application asking for a 32 bits java VM runtime. Nothing more, nothing less. But now is very easy to fix:
  1. just get a 32 bits java VM
  2. adjust epf-composer/epf.ini to use it
In my case I've installed a Java 1.7 (in my case from the same Russian Fedora repo):


and then change ~/epf-composer/epf.ini from this:

-data
@user.home/EPF/workspace.151
-vmargs
-Xms64m
-Xmx512m

to this:

-vm
/usr/lib/jvm/java-1.7.0-oracle-1.7.0.79/jre/bin/java
-data
@user.home/EPF/workspace.151
-vmargs
-Xms64m
-Xmx512m

Please note the precise path may be different in your system but in any case it should point to a 32 bit java binary.

Then you just need to launch EPF and you are ready:

$ epf-composer/epf


Enjoy.
