Mysql

Michael “Monty” Widenius ha publicado una solicitud a la comunidad para salvar el futuro de MySQL. En su peticiÃ³n proporciona mÃºltiples formas de ayudar.

Creo que hay que dar la mÃ¡xima difusiÃ³n a la peticiÃ³n, ya que el problema puede ser extremadamente grave.

Open Sistemas ha enviado una carta a la ComisiÃ³n Europea (comp-merger-registry@ec.europa.eu) que replico a continuaciÃ³n:

Dear sir,

I don’t trust that Oracle will take good care of MySQL and MySQL should beÂ divested to another company or foundation that have everything to gain byÂ developing and promoting MySQL. One should also in the future be able toÂ combine MySQL with closed source application (either by exceptions, a moreÂ permissive license or be able to dual license MySQL under favourable terms).

Name: Fernando Monera
Title: CEO
Company: Open Sistemas de InformaciÃ³n Internet, S.L.
Size of company: 50 people
How many MySQL installations: >500
Total data stored in MySQL (megabyte): >1000 mb
For what type of applications is MySQL used: web applications
Should this email be kept confidential by EC: No

Regards,
Fernando

Por Â favor, dad la mÃ¡xima difusiÃ³n al post original de Monty!!.

Interesante movimiento de Redhat al comprar KVM

fmonera — Fri, 05 Sep 2008 13:36:10 +0000

Para quien no lo sepa aÃºn, Redhat ha comprado la empresa que desarrolla KVM, Qumranet. Recuerdo que KVM es en este momento el Ãºnico sistema de virtualizaciÃ³n soportado por Linux en su rama principal.

Teniendo en cuenta el bajo rendimiento de Entrada/Salida que proporciona Xen en algunos entornos (lo digo por experiencia) y las pocas posibilidades que tiene Xen de ser aceptado por completo en la lÃnea principal del Kernel, me imagino que este movimiento va a recolocar algunas piezas del mapa de proveedores de VirtualizaciÃ³n.

Por otro lado, Virtualbox acaba de sacar la versiÃ³n 2.0. Virtualbox es otro sistema de virtualizaciÃ³n recientemente adquirido por Sun Microsystems. Aunque desde el punto de vista de arquitectura Virtualbox es una maravilla y puede funcionar de forma confiable en entornos de servidor, su uso principal sigue siendo la virtualizaciÃ³n en entorno de escritorio personal. Es el equivalente a VMWare Workstation, de hecho, la interfaz es muy parecida. TodavÃa tengo que probar la nueva versiÃ³n, asÃ que no comento nada de momento.

En general, es interesante volver a comentar la misma idea de siempre. Todo software horizontal / de infraestructura (sistemas operativos, bases de datos, virtualizaciÃ³n, ofimÃ¡tica, navegadores, …) va a ser copado por el Software Libre tarde o temprano. No hay ninguna posibilidad de crear un modelo de negocio “sostenido” alrededor de este software si no es con Software Libre. A ver si le entra en la cabeza a algunos (Microsoft, Oracle, …).

Â¿He dicho alguna vez que me encanta Redhat?

GTD: Improve integration in ThinkingRock

fmonera — Thu, 04 Sep 2008 17:48:43 +0000

This article is about the way I organize myself (I happily follow the “Getting Things Done” metodology). To help me manage tasks and projects, I use ThinkingRock.

I have finished the infrastructure for integrating of external apps into TR (by using some scripting magic and the Notes field). At the moment it is a quick hack, but “it works for me (TM)”

This article complements the KMail integration post which can be found here: http://www.thinkingrock.com.au/forum/viewtopic.php?t=2321

At the moment, I have integrated:

Freemind: For mind mapping and many other tasks (it is a very important app for my daily work)
Openproj: A MSProject like app for managing complex projects
TiddlyWiki: A very interesting tool for structured documentation

Adding new apps (openoffice, gimp, …) is really easy, as everything is done outside TR and without programming. I will come on this topic later.

VISION
I have just created a project/action in TR, and now I want to:

Attach a mindmap from an existing template very easily without bothering with filenames and folders
Attach a complex project from an existing template very easily without bothering with filenames and folders
Attach a new spreadsheet from an existing template very easily without bothering with filenames and folders
Keep everything related to the main project/action
Have all the docs available with a single click in the link
Easily create templates (for example I have a mind-map template with all the things I have to ask to a customer interested in elearning).
If I want to add 4 different files to an action, I just have to: launch the script, select the templates and press enter (this is not completely achieved at the moment )
Everything must be safe (no modifying or reading the xml file) and must survive between updates of TR

MAIN PICTURE

On the TR side, the magic is done by linking to files in the “notes” field. This links are opened by xdg-open, which in fact calls the default application for the file. Nothing new here.

On the Linux side, there is a script (I have created an icon in my panel) which:
1) shows the available templates (you can select one or more)

2) asks for -optional- base names (names and paths are not important as they will be correctly linked from within TR)

3) creates folders to store the new files (it ensures there will be no collisions, so you can have many “Brainstorming” base names for different projects ). You can choose a folder if you want, but I see no reason for that. This is done through an option’s window, which in many cases you can just accept the defaults and press enter.

4) creates new files based on copies from templates (mm, sxw, pdf, …) and puts them in the new folders

5) Shows a popup with the text you have to paste into TR

THE TEMPLATES

To find the available templates, the application looks into the TEMPLATES folder (see below). There it finds a folder for every template.

Inside every folder, there is a single file named exactly as the folder plus the corresponding extension (NOTE: This will probably be improved in future versions to be able to put more than one file on each template). You can edit the file with the corresponding application to adapt the template to whatever you want:

Obviously, you can put there whatever you want. Any kind of file.

In the end, the template file will be copied to the destination and renamed to the base name you choose.

THE CODE (and install steps)

1) Select all the text and paste it to a text file, named “tr_integration.sh” and assign execution rights (chmod 755 tr_integration.sh).

2) In the code, you will need to change:
- PROYECTOS: which points to a folder where you want to store all files and folders created
- TEMPLATES: which points to the templates folder

3) Create a shortcut available easily

Code:

#!/bin/bash
# Name: tr_integration v.0.1
# License: GPL v3
# Author: fmonera at opensistemas dot com

PROYECTOS=”/home/monera/temas/personal/proyectos”
TEMPLATES=”/home/monera/temas/personal/templates”

# List of items
for I in `ls $TEMPLATES`
do
WANTEDLIST=”$WANTEDLIST $I $I off ”
ITEMS=”$ITEMS $I”
done
WANTED=`kdialog –checklist “Select items to create:” $WANTEDLIST`
if [ "X$WANTED" == "X" ]
then
exit
fi

# OPTIONS
OPTIONLIST=”newfolder NEW_FOLDER on”
OPTIONS=`kdialog –checklist “Select options for this files:” $OPTIONLIST`
echo $OPTIONS
# Parse options
NEWFOLDER=`echo $OPTIONS | grep -c newfolder`
# end parse

# dir
if [ "X$NEWFOLDER" == "X1" ]
then
NOMBRE=`kdialog –inputbox “Base name for the folder (no special characters please):” temp_folder`
DIR=`mktemp -d –tmpdir=”$PROYECTOS/” “$NOMBRE.XXXX”`
if [ "X$NOMBRE" == "X" ]
then
exit
fi
else
DIR=`kdialog –getexistingdirectory $PROYECTOS`
if [ "X$DIR" == "X" ]
then
exit
fi
fi

for I in $WANTED
do
# Unquote
I=`echo $I | cut -b 2- | cut -d’”‘ -f1`
# Create documents
NOMBRE=`kdialog –inputbox “Base name for $I (no special characters please):” $NOMBRE`
echo “NOMBRE: $NOMBRE”
echo “DIR: $DIR”
SOURCE=`find $TEMPLATES/$I -type f`
EXT=${SOURCE##*.}
DEST=$DIR/$NOMBRE.$EXT
cp $SOURCE $DEST
done

# Format TR Text
for I in `ls $DIR`
do
EXT=${I##*.}
FORMAT=`basename $I “.$EXT” | sed ‘s/_/ /g’`
TEXTO=”$TEXTOÂ Â· $EXT: [file:$DIR/$I|$FORMAT]”
done
TEXTO=”$TEXTO
”
kdialog –textinputbox “Paste into ThinkingRock:” “$TEXTO” &

You will need kdialog and mktemp. Both are available in every unix system I know.

It might work in Windows and/or MAC if you install KDE4 and adapt a bit the code. You will probably need Cygwin or, at least, mktemp for your environment. I don’t see major problems for that. Sorry, no support for Windows as I am a free software man since 1997

RedHat ha liberado Satellite: Spacewalk

fmonera — Tue, 24 Jun 2008 08:36:13 +0000

QuÃ© gran noticia que RedHat libere Satellite. Si no me equivoco, era la Ãºltima pieza no libre de RedHat. El nombre del proyecto es Spacewalk.

Spacewalk/Satellite es un software de gestiÃ³n de sistemas Linux en una red. EstÃ¡ completamente integrado con su sistema de gestiÃ³n de mÃ¡quinas virtuales y hace realmente sencilla la administraciÃ³n de software, actualizaciones, nuevas instalaciones, versiones, mantenimiento y otras tareas de gestiÃ³n de red.

De momento va con CentOs y Fedora, pero me imagino que rÃ¡pidamente saldrÃ¡n plugins para el resto de distribuciones. De esto va el Software Libre, Â¿no?

AdemÃ¡s, lo que mÃ¡s me gusta: licencia GPL v2, sin mÃ¡s complicaciones. Pienso que esta licencia en concreto es la que mÃ¡s beneficia al Software Libre a largo plazo ya que da suficiente libertad para que desarrolladores externos estÃ©n motivados para contribuir y mejorar el software, mientras que como empresa te proporciona una protecciÃ³n jurÃdica muy alta ante la posibilidad de que te puedan plagiar el cÃ³digo fuente.

Muy buena noticia la liberaciÃ³n, y mÃ¡s aÃºn la forma de liberaciÃ³n. Se nota cuando una empresa sabe de quÃ© va esto.
