Chaos Mind getting into order

Archive for the ‘Training’ Category

Yes, I did it! I took the 2 weekend salsa teacher course in EDSAE dance school, in Lisbon. The teacher, Bibi Fernandes, was a amazing teacher that explained, with detail, a method how to teach salsa. I learn a lot of material: shines, new steps, sequences, body flow, warm up exercises! (I have material for almost 1 year!).

I don’t know when I’ll start to give classes (if I will start at all), but this course is an excellent experience for everyone!

Next weekend, I’m going to be there again, to have a classe with Super Mário, the million moves man 🙂

Mooshak is a system for managing programming contests on the Web. Mooshak’s basic features include automatic judging of submitted programs, answering to clarification questions about problem descriptions, reevaluation of programs, tracking printouts, among many others [reference: Mooshak’s website].

Since I want to have a dedicated server for it (thanks, Algardata), I had the oportunity to install on a fresh debian etch system. Unfortunately, the installation manual is very incomplete (even the README file bundled with it), so I created this small step-by-step tutorial what will help you to install it flawless.

Warning: This rough tutorial was the solution to install mooshak only. Mooshak configuration, setting users, competitions, etc, is far from the scope of this tutorial.

1 – Requeriments:

For this tutorial I used a debian etch 4.0r3 network install CD and I installed the basic system and nothing more.

Mooshak needs the following software to work:

  • Tcl 8.3 or greater;
  • Apache 1.2 or greater;

Well, in my case I need a little more, because this is a very basic system. To be able to install Mooshak, it’s needed to install:

  • xsltproc (version: 1.1.19)
  • lpr (version: 2006.11.04)
  • rsync (version: 2.6.9)
  • gcc (version: 4.1.1)
  • libxm2-utils (version: 2.6.27)

The version number next to each package it’s the one that I’ve installed. It doesn’t mean that it can’t work with a minor version, but I don’t have that knowledge.

2 – Requirements installation:

To install it all at once:

aptitude install tcl apache2 xsltproc lpr rsync gcc libxml2-utils

This command line worked fine for me. I just recommend to see which extra packages it would install, but they are safe and expected.

3 – Mooshak installation

Now our box is ready to install Mooshak. Just download the lastest stable version and install it:

% tar xzf mooshak-version.tgz
% cd mooshak-version
% su	
# ./install
Prerequisites Ok. Installing Mooshak on debian, Apache 2.2
home dir created
data.tgz copied
source.tgz copied
setting file permissions ... done
connecting to host [your-server's-name] ... connected!
Mooshak installation seems OK

You can check it from the webserver http://%5Byour-server’s-name%5D/~mooshak/cgi-bin/info

4 – Configuring Apache2

Since mooshak site it’s from a system user (mooshak), you will need to activate userdir module:

# a2enmod userdir

Next step is to configure /etc/apache2/mods-available/user-dir.conf and add the following lines between IfModule section:

        <Directory /home/*/public_html/cgi-bin>
Options +ExecCGI -Includes -Indexes
SetHandler cgi-script

Now, it’s time to reload the apache2 server:

/etc/init.d/apache2 reload

Final Thoughts

Mooshak have big lacks of documentation and it’s build in TCL, which it doesn’t help to be widely adopted. Meanwhile, it’s quite popular among portuguese universities because of programming contests, or even it’s used in programming classes to test students.

I would like to see a mooshak version using a more popular language (PHP, Ruby, JAVA, etc.).

Finally, I invite everyone to help me to keep this tutorial up-to-date.


I’m going to php|tek 2008 in Chicago, next May. Since I’m doing all my trip/conferences planning on iCal, I made a calendar of it, because the official website doesn’t have a offline calendar!!

So there is the my calendar file. Feel free to add it and to help me to keep it updated.

If you are going to php|tek 2008 as well, drop me a line!


Um amigo meu mandou este email para a mailing-list interna:

Alguns de vocês não sabem mas estou neste momento a trabalhar no estrangeiro às custas de um programa chamado Inov Contacto.Este programa oferece ordenados que vão desde os 1800 aos 2200 euros e uma oportunidade de ir trabalhar para qualquer parte do mundo. Se já tens a licenciatura em mão, não tens nada para fazer ou estás a trabalhar e apetece-te uma mudança radical… faz como eu fiz…INSCREVE-TE:

Nota: O site deixa muito a desejar em usabilidade…

Vai-se realizar em Coimbra, nos próximos dias 21 e 22 de Fevereiro, uma formação intitulada  “Hardening Your Software Projects“, organizada pelo CERT-IPN. A ver se consigo ir 🙂

Fico muito feliz em saber que é possível realizar o curso “Certified Scrum Master” em Portugal. Pretendo fazê-lo (até ao final deste ano) pois creio que é uma mais valia a nível profissional e também pessoal, já que o Scrum é, na sua essência básica, um conjunto de políticas de bom-senso aplicáveis em qualquer área.
