I love to be back to Slackware, my very first distribution. However, there are a couple of things that I’m missing from the other more comfortable distributions. From among them, I totally miss Network Manager.
I saw many people asking in forums on how to install Network Manager in Slackware 13.0. There is Wicd, already present in Slackware “repositories”. Every Slackware maniac will tell you that it does the same job of Network Manager, but I don’t agree. It does not always work and is more complicated to be configured than NM.

Anyway, I’m going to explain to Slackware newbies the dirty way to have a fully working Network Manager on Slackware 13.0. This method is totally against Slackware philosophy and will also replace some important libraries of the system! Anyway, the packages being replaced are prepared from the guys behind GNOME SlackBuild, a project to bring Gnome in every Slackware release.
You have two way to have Network Manager in your Slackware: either install the entire Gnome from them (or any other similar project) or use slapt-get against their repositories and just install Network-Manager. Here are the instructions. All the following actions must be performed as root user:

1. Download, install and configure slapt-get. Instructions are provided on their website.
2. Update your system with:
   

   slapt-get –update
   slapt-get –dist-upgrade

3. Add GNOME SlackBuild repository in /etc/slapt-get/slapt-getrc:

   SOURCE=http://mirror.switch.ch/ftp/mirror/gsb/gsb-current/

4. Update the list of available packages and replace some system packages:

   slapt-get –update
   slapt-get –add-keys
   slapt-get –install –reinstall alsa-lib bluez glib2 gtk+2 libwnck

5. Now install Network Manager and its GTK applet:

   slapt-get –install NetworkManager network-manager-applet

6. Be sure that dbus, hal and NetworkManager daemons will be loaded at boot time:

   chmod +x /etc/rc.d/rc.messagebus /etc/rc.d/rc.hald /etc/rc.d/rc.networkmanager

7. Add your user to the plugdev group. Edit /etc/group, find the line

   netdev:x:86:root

   Add your username after root (bodom_lx is my case)

   netdev:x:86:root,bodom_lx

8. You are quite finished now! Log back as normal user and create a startup script for network-manager-applet:

   cd ~/.kde/Autostart/

   Create a file called nm-applet.sh with the following content:

   #!/usr/bin/bash
   nm-applet –sm-disable &

   Give it execution permission:

   chmod +x nm-applet.sh

   .

Reboot your system. Everything should work fine now.

To uninstall Network Manager and restore the system as it was before the installation follow these instructions, as root::

1. remove any GNOME SlackBuild package using:
   

   removepkg /var/log/packages/*gsb

2. Comment GNOME SlackBuild entry in /etc/slapt-get/slapt-getrc:

   #SOURCE=http://mirror.switch.ch/ftp/mirror/gsb/gsb-current/

3. Update your slapt-get sources and re-install the replaced Slackware packages:

   slapt-get –update
   slapt-get –reinstall –install glib2 libwnck alsa-lib gtk+2

4. Toggle execution permission to the auto-started network-manager-applet. Log back as normal user and type:

   chmod -x ~/.kde/Autostart/nm-applet.sh

Feel free to comment any suggestion.

While searching for solutions on adopting Django for the server side of our Dynamic Car Pooling system, I found two very interesting projects:

• WAPI – a framework which abstracts the details involved in publishing an API and translates class methods to API methods, serializing the objects returned when possible. WAPI handles authentication, too, and other advanced functions. It’s an amazing, fully Django compatible system that currently works over ReST (JSON, XML, YAML) but not with XML-RPC. Therefore, I contacted the author to have some information about the status of the project. It would be very interesting in our system, to provide API and XML-RPC services just by using his layer
• RPC4Django – provides XML-RPC and JSON-RPC support to an existing Django project. It promises a XML-RPC interface by just adding the decorator @rpcmethod to an existing python function. It also fully integrates with Django authentication framework

I’m going to experiment with these two tools. Obviously the first one is the most interesting because of its ability to “export” services in more formats. But the most important protocol for us is missing. Let’s hope it will be added soon!

While I am waiting for my wiki to be setup, I’m updating here my first week of work. I read lots of papers regarding dynamic car pooling and friends. Most of them are listed on this MIT website and on dynamicridesharing.org. The second site is maintained by Dan Kirshner, the author of three (unlucky) experiments regarding dynamic car pooling.
I actually selected 13 publications for my scope. I’m going to publish the list as soon as I’ve got my wiki. What I’m going to do is to review them, comparing my work with the excellent one done by Hannes Zimmerman and Yann Stempfel (Current Trends in Dynamic Ridesharing, identification of Bottleneck Problems and Propositions of Solutions).

Pomotux is  a C++ activity manager for the Pomodoro Technique created by Francesco Cirillo, a member of the XPlabs crew. The program focuses on the basic features of the technique. It does not focus on advanced techniques, such as the prediction of the number of pomodoros needed for an activity.

About the Pomodoro Technique

The Pomodoro Technique is a time management method that can be used for any kind of task. For many people, time is an enemy. The anxiety triggered by “the ticking clock”, especially when a deadline is involved, leads to ineffective work and study habits which in turn lead to procrastination. The aim of the Pomodoro Technique is to use time as a valuable ally in accomplishing what we want to do in the way we want to do it, and to enable us to continually improve the way we work or study.

The Technique is heavily explained on a 60+ pages book published on the website. Please visit the official website for more explanations.

A running Pomodoro

We implemented Pomotux for the Software Engineering Project course, and it currently works under Gnu/Linux. Project page is located here. We are looking for coders to port it under Mac Os X, *BSD and Windows!

Get Pomotux

Pomotux has been developed for the Software Engineering Project course at the Free University Of Bolzano by Daniel Graziotin, Riccardo Buttarelli and Massimiliano Pergher. We decided to release it under the GPL 3 license and host the code on Google Code. Everybody is free to contribute and join the project.

Pomotux is hosted on: http://code.google.com/p/pomotux/

Source code is available on: http://code.google.com/p/pomotux/downloads/list

The wiki contains more information and installation instruction, and a better description of the of the system implementation and Software Engineering outcomes

Activity Inventory Sheet

Technology Overview
The System has been developed using

• C++ programming language (coding standard)
• QT framework (4.5)
• SQLite Database library
• LiteSQL Object Relational Mapper framework

Useful tools used during development:

• CXXTEST Testing Framework
• CPPCHECK code analyzer
• Artistic Style code formatter

Project Status
The project succesfully passed the exam with a maximum degree. It has been developed under Gnu/Linux and has only been tested under Gnu/Linux (various distributions). It should be cross-platform. The only component that brakes cross-platform is LiteSQL, that should work on any *NIX system but not Windows. We are looking for testers and people to port it under Max Os X (and possibly) under Windows

BD-review is a dynamic website to allow people to review releases (albums, demos, EPs, singles) of (young, unsigned) music bands. The project is the outcome of the Internet Technologies course at the Faculty of Computer Science of the Free University of Bolzano. The requirements of the project were to build a website using a small subset of JavaEE technologies, without the use of web-frameworks.

A screenshot of a Review

The project is not really meant for production use. It was made as a strong, working and correct base for studying JavaEE academically. It should be useful for every student (also non-student) willing to have an overview on JSP and study it. The code is well-written, uses MVC, and the whole project is documented in detail in a 20+ pages report.

Read more on the project page, download the sources and play with it! Please let me know about your experience with BD-review code.
