The last year I was quite busy with Neurowork, but I've finally moved the blog to Wordpress.

The next Friday, Neurowork will be organising the 2nd WHYFLOSS Conference with talks related with Free Software, Linux and Java in Escuelas Pias, Madrid.

The definitive program can be seen here.

See you there! :-)

The last months I was pretty busy working and traveling, so I didnt have time to blog about it. Now I'm working in Qindel, a free software company. Here we are searching professional free software engineers to work with us, so if you are interested in working in a Free Software company, send me your resume to asanchez_at_qindel_dot_es

In the next Saturday I will be talking about Mono project in UNED university in Madrid. Read more about it here.

The dates of the GUADEC are approaching and still I have not been able to confirm my attendance, I finally hope to be able to go.

Pretty busy this week with the Unix Meeting. Some interesting talks like "Present and Future of GNOME" by Rodrigo Moya and "Present and Future of KDE" by Aaron Seigo discussed the future of the both desktops and the new projects to enhance performance, usability, and eye-candy.

There were some other talks related with Ubuntu or Edubuntu. Both Michael Meeks' presentation about OpenOffice and the Xen presentation by Evaldo were very interesting and technical.

The new GNOME 2.13.3 release sounds very promising, and the new optimizations have greatly increased performance. The pango font rendering is now incredibly fast, and the amount of I/O is less abusive now with some interesting gconf optimizations.

Tomorrow some friends and I are going to the Debconf-es II. If you are there and want to meet, send me an email.

A long time without posting anything. Today I gave a talk in the FIST conferences related with Intrusion Prevention Systems (IPS) about how prevent security web problems with Snort and ModSecurity.

Javier Fernandez Sanguino was also talking about the OWASP project and presented some interesting applications to review security in web applications using Webgoat and Webscarab.

The latest weeks I was pretty busy organizing the Unix Meeting 05, a network irc meeting in Uninet network.

Speakers like Aaron Seigo, Rodrigo Moya, Cesar Lopez Nataren, Jose Nazario, Marcus Brinkman or Rik Van Riel will be talking about the desktop, security and operating systems.

The last weeks happened a lot of things like the II GUADEC-ES where I was talking about Freedesktop and the GUADEC in Stuttgard.

There were awesome the talks in GUADEC, I couldn't go this year but there were some interesting talks about Cairo, Gstreamer, GNOME Applets, Lighting talks talking about Xgl, Luminocity samples, etc. Thanks to the fluendo people for streaming. :)

In the other side I decided to change Gentoo to Ubuntu in the laptop and the server, I was boring to compile everything, but I have to recommend *NOT USE BREEZY*, it's very unstable, I have had problems with it, *USE HOARY*. Actually is a kubuntu, but it has the same packages, so I installed GNOME and KDE in the laptop.

Now I'm using again GNOME, but I had some problems and I will comment how I solved it.

First, I want to migrate my mails from Kmail to Evolution, but Evolution doesnt have the posibility to import Maildir or Kmail mails, but you can import a single mbox file. In this situation the import filter is better in Kmail because you can import mails from Evolution, Netscape, Thunderbird, etc.

Anyway I stored every folder in a mbox and later I imported from Evolution, so now I have retrieved every mail in Kmail. Later I missed the posibility to have a background per desktop, but I found Wallpapoz, so now I have the same feature than in KDE desktop. It would be nice a integration of wallpapoz in GNOME.

I also had problems with shortcuts in GNOME, perhaps a bad installation, but now I have set every shortcut I need to handle, except currently I don't know why I can't change to another desktop with Ctrl+Alt+position. If you look KDE you have local shortcuts in every application, so It's easy to customizate every application to move faster, anyway there is a trick in gconf to make the same in GNOME.

Currently I think it's a little difficult to change from KDE to GNOME, because applications in KDE have more features, and there are somes I'm missing. I think it would be nice to have a usability study of people from GNOME using KDE and viceverse, it could be a good way to integrate more the desktops and share common things.

For example, now I would like to have the bookmarks from Konqueror in Firefox/Ephiphany, but now I think is not posible.

Also I miss the konqueror hybrid between browsing web and folders, because in firefox the views are not the same than a folder view when you are looking a http/ftp site with some files. Anyway I'm so proud of desktop, I think both KDE and GNOME desktops will rock in one or two years where the people will adopt more extensively. I expect to be a reality the 10% of GNOME desktops in 2010 like Jefff commented. :)

And in the work, currently I'm making some applications using Mono framework. I'm very happy with the Mono development, although I started to work in 2002, now I dont have so much time to contribute to Mono core, but I consider so stable to make applications with it.

I was testing crossdev tool to cross-compile binutils, gcc, glibc and linux kernel to powerpc.


Lastly I have been playing with Mono framework and the GNOME libraries, but I find the problem in portability, so I'm a little limited when I want to make a portable application. After changing the code from textview to gtkhtml in an application to render the output, I had to revert the code because gtkhtml only works in GNU/Linux. Then talking with Zack, he talked about Gecko# and the monodoc port (without gtkhtml), so I changed the code. Now it renders HTML with Gecko# and gtkmozemb. :-)

Anyway Tor and Zack are making an awesome work, I think when we have an Orbit/bonobo working in windows more people will use GNOME applications. Currently KDE developers are working in a portable desktop for the 4.0 release and in the GNOME area there is some work porting Evolution/Beagle/Monoapps.

Zack also worked in gtksourceview, but I think we will have to wait to look a portable Monodevelop.


The last week I was talking about the Linux kernel in the University in the IV Jornadas de Software libre. I gave an overview of the sources talking about security, networking, scheduling, new archs, drivers, etc.


Now I'm working in s21sec, a spanish security company, since the last November. I'm really happy with my new work, but I have been too busy. I will try to blog more frecuently.


A few weeks ago I was attending with some URJC friends to the FOSDEM. I knew some security developers like Martin Roesch (snort) and Gerald Comb (ethereal). They were talking about the future of the tools. I also attended to some another interesting conferences of some known developers like Mathias Elritch about KDE, Alexander Larsson about Nautilus and Alan Cox. It was really funny and I had the chance to make the LPI 101 exam.


- Drag and drop tabs in konqueror.
- Cut and paste in Konsole (btdownloadcurses/wget)
- Kde-volume-manager (the same gnome-volume-manager using libhal, sysfs, hotplugging, udev, qt-dbus/dcop and an additional kde application).
- KMail plugins. (like EPlugin in evolution)

Integration between desktops.

- Feeds reader: Use the same location to store the feeds and the configuration file with your rss url's. (akregator/blam/..).
- Mail applications: The same directory for mail. (kmail/evolution/..).
- Gtk styles in KDE or Qt styles in GNOME. (gtk-qt-engine or a posible qt-gtk-engine).
- Same global/local keybindings for applications.
- Integrate KDE applications in gnome-panel (both use the same freedesktop standards).


Miguel has posted some interesting notes about the Mono meeting in Boston.


- Filter the html contents.
- Follow chm links in the KHTMLPart.
- Toolbar.
- Some actions like: zoomIn, zoomOut, print a chm, ...
- Command Line.
- A new kchmListViewItem to enhance the view.


In two weeks we will celebrate the second GNOME meeting in Madrid, in the URJC. I will be talking about the freedesktop project.


It would be really useful to have a command line option to choose the workspace when your application is launched.

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.
