Tech Source From Bohol: "Without hesitation, I said yes and not even thinking of how I'll do it. That time, I was biting my nails and learning deeper about Python. My first problem was the GUI...Tkinter."

L'animal serpentait dans la mairie de cette petite commune d'Ille-et-Vilaine.

Question:

What is the different between:

fd = open("/tmp/foobar.bin") while True: chunk=fd.read(CHUNK_SIZE) if not chunk: break print len(chunk)

and

fd = open("c:/tmp/foobar.bin") while True: chunk=fd.read(CHUNK_SIZE) if not chunk: break print len(chunk)

Just in case, the answer "c:" is not wanted, that's too obvious.

Another hint, both files are non-ascii files.

 

 

 

Answer:

Ok, the answer. First of all, as you can see, one of the open directives is running on Unix (in this special case on Linux).

The other one runs with the same version of Python on Windows XP.

Both files are non-ascii files, which means, somewhere in between there is a character which could lead to problems on windows, while reading the file.

Now on Linux somehow this file is opened correctly as binary. The official syntax for opening binary files in Python is open(<filename>,"rb") (well, to be more precise "read binary").

On Linux, as said this file is opened correctly in binary mode, while on Windows the default opening mode is ASCII.

You can see the difference when you follow the "print len(chunk)" data. Somehow, if you have the "EOF" character somewhere in the file when opened in ASCII, python stops reading the file and thinks the file ended. Which is somehow not the real truth.

This behaviour had cost me now at least 2 hours of debugging, because I was in the thought, Python2.5's behaviour should be the same on Windows as on Linux. I was mistaken.

But why? Shouldn't it be the same? Is there any rational why it's different on Linux and on Windows?

If some Python guru can enlighten me, so that I can understand...that would be great :)

After several years of development, and a steadily growing user base, the open-source Python Web framework project reached its 1.0 milestone. Significant new features include an improved ORM framework, better Unicode support, and a refactored administration application.

Toulibre organise une rencontre autour des Logiciels Libres le mercredi 10 septembre 2008, de 19h à 23h au Centre Culturel Bellegarde, 17 rue Bellegarde à Toulouse.

Pendant toute la soirée, venez poser vos questions au sujet du Logiciel Libre et trouver de l'aide pour installer ou utiliser des Logiciels Libres sur votre ordinateur. Pour cela, vous pouvez si besoin apporter votre ordinateur, un accès Internet est disponible sur place. Dans l'idéal, si vous venez avec votre ordinateur, essayez de nous prévenir par courrier électronique à contact at toulibre.org en décrivant vos besoins ou votre problème, de manière à ce que amenions les Logiciels Libres nécessaires voire à ce que nous fassions quelques recherches préalables pour mieux vous répondre.

À 20 heures, deux courtes présentations auront lieu :

• La première, assurée par Florian Birée, sur Crunchy, un logiciel libre dédié à l'apprentissage du langage Python en intégrant son interpréteur dans un tutoriel sous forme de page web. La présentation montrera les possibilités de Crunchy pour écrire et dynamiser un tutoriel, ainsi que l'usage qui peut en être fait pour apprendre le langage.
  
• La seconde sur OpenMoko, un projet destiné à fournir un téléphone portable doté d'une couche logicielle entièrement composée de Logiciels Libres.
  
  Depuis début juillet 2008, le Neo Freerunner est proposé à la vente. Bien qu'encore réservé à un public un peu averti en raison du manque de maturité de la couche logicielle, il devrait rapidement devenir accessible au plus grand nombre grâce aux efforts de la communauté pour améliorer les applications. Thomas Petazzoni proposera une présentation du Neo Freerunner, pendant laquelle un exemplaire de l'appareil sera accessible.

Just like last year, I'll be attending and presenting at Oslo's JavaZone conference in less than two weeks. My presentation is called "Dynamic languages and frameworks in an enterprise application server world - an approach with GlassFish v3".

I'll describe the reasons why one would want to run dynamic languages and associated frameworks on top of an application server and describe several approaches to implement this. I'll illustrate this for JRuby On Rails, Groovy and more using the forthcoming GlassFish v3 Prelude release (scheduled for next month). If you're interested in the Java side of GlassFish v3 (fast startup, dynamic loading or services, etc...), I think you'll get something out of it too. The talk is the first one on the first day, competing with 3 Norwegian talks and Erich Gamma himself. Wish me luck!

Here's an early list of the talks I'd like to attend (as always, I'll attend 50% max): • RESTful Web Services with Spring (JSR311 or not?) • Qi4j - a new approach to old problems (never heard Rickard present) • Project Hydrazine: JavaFX Open Cloud Computing Platform (had no time to look into this since J1) • Quercus (the list of PHP apps it runs is very impressive) • Taking Apache Camel for a Ride (OpenESB has a service engine for Camel) • Spring == XML, XML == sucks therefore Spring == sucks? (will the content live up to the catchy title?) • Real-world OpenESB, best practices and experiences (There's always something to learn from real-world experiences) • Scala? Ruby? Erlang? Python! (no matter how many dynamic languages we support on GlassFish v3, there'll be more to look at) • Zero Turnaround in Java Development • What's new and cool in Portlet 2.0 (Julien just left JBoss to join eXo) • How Can Amazon EC2 Benefit from the Elastic Grid Solution? (I don't care what Gartner says, cloud computing can be real today) • Panel: Alternative and Emerging Languages

Hello Planet!

It was 27th August when I was approved Kubuntu Member (Yay!) and thus became allowed to join the Ubuntu Planet :) Let me introduce myself (in short first, who wants to read more takes the following longer version):

I am...

• 23 years old
• a student of business information systems
• a linux and kubuntu user since 2005
• a kubuntu-de.org-member since 2006 (doing support, promotion, editorial stuff, treasuring, moderation)
• learning python with PyQt4 and PyKDE
• gonna help with Leonov
• having a Wiki-page with more details

So, here's the long version:

I am a 23 year old student (Business Information Systems), living in Heidenheim, Germany. My first contact to Linux was in 2005, when i installed SuSE 9.0 (or .1? or .3? or so?) on my IBM Thinkpad T22. A month later, due to unresolved problems i switched to Kubuntu, which i knew was used at the youth organisation of my place where i did civilian service. That worked right from the start and with some help at kubuntu-de.org (kubuntu.de in former times) i claimed the first high obstacles. Since, I am a fan of Kubuntu.

I became active in the forum of kubuntu-de.org, until i was asked wether i wanted to do more. I joined the IRC network and became moderator in the forum and member in general. Since, i started helping in editorial stuff (writing, translating, checking and publishing), promote kubuntu at fairs and conferences at our booth, together with neversfelde started the donation account and since august became community carer (this means helping new people to join our community, managing problems in the community, etc).

In my spare time (after gf and community work) i find time to read (esp. Stephen King) and code (learning Python, this will be part of kubuntu work in some time i hope). I'd play soccer, as i used, but currently it does not fit in my schedule, but this will change in future again, i hope. What I am doing all the time is listening to music (The Offspring ftw!).

Okay, now you know something about me. If there is a question or two (or more) feel free to ask :)

Cheers
Arthur aka Blizzz

Day 4… and what a great day it was, here a blow-by-blow recap of what happened yesterday:

• Ara Pulido kicked off the day with “Automated Testing of the Desktop“. Ara showed us what amazing stuff she was working on. Check out this fine example: it shows how easy it has become nowadays to test the integral parts of our Ubuntu Desktop. The audience asked lots of interesting questions any everybody left the session with a much better idea of what’s happening in #ubuntu-testing.
• Afterwards I did another session called “How do I fix an Ubuntu bug“. The main aim of these session was to demonstrate how easy it is with Harvest and the Ubuntu development tools to make Ubuntu better today. That you don’t need a degree in rocket science, just a knack for trying to make things work again, some patience and that you’re good at team-play. The session was well-attended and the questions showed that the audience was clearly motivated to shake out bugs of Ubuntu. We even managed to fix two bugs during the session. The shipment of awesome-ness clearly has arrived!
• Jonathan Riddell delivered the third session that day and showed how to write a “WebKit browser in PyKDE“. Everybody was very impressed by how easy it is to use WebKit in PyKDE. Have a look at the examples yourself: this is clearly next-generation awesome stuff.
• Alexander Sack afterwards gave a great introduction to “Having fun with the Mozilla Team“. This is one of the very very busy teams we all expect the best from. Alexander explained all the areas that require work (extensions, bug work, maintenance of all mozilla-related packages, etc.) At the end of the session he demonstrated the ease of packaging Mozilla extension. Rock and Roll!
• Steve Langasek as one of the Heroes of the Archive Admins delivered a great session on “How to avoid making Archive Admins unhappy“. The session was a great opportunity to find out almost everything that’s reviewed with great scrutiny, especially since the session was a relaxed discussion, it invited everybody to join in.

The week went to its end very very quickly. Let’s have a look at what’s happening today:

• 16:00 UTC: What a start of the day, we’ll kick off the day with “Ask Matt“! I’m pretty pleased Matt has taken time out of his schedule to answer all kinds of questions. As he said, he’s particularly interested in questions about community-oriented development, the software technologies used in Ubuntu, and what we do at Canonical. Bring it on!
• 17:00 UTC: Lars Wirzenius takes the second slot and delivers a great session about “Unit testing with Python code, with code coverage measurement”. Learn how to write better code by better testing your code. Learn from Lars to help out on his mission: less bugs, better software!
• 18:00 UTC: Talking about good software: Evan Dandrea is up next and will give you an “Introduction to the Installer Team“. Ask all your questions about the installer itself, how to get involved and what needs doing to make the installer even better.
• 19:00 UTC: Another introduction is due: Kees Cook and Jamie Strandboge will give you the “Introduction to the Security Team“. These guys have done excellent work all over the place and the team is slowly growing with more and more participants. If you’re interested in making Ubuntu more secure, this is your chance to help out and get involved.
• 20:00 UTC: The last session of the week is the “Kernel Discussion“. Master of Awesome-ness Ben Collins will steer us through the session and will answer questions about all facets of the Ubuntu Kernel experience: your first steps at joining in on Ubuntu Kernel fun, how the team works, etc.

Come in masses, this is the last day of this Ubuntu Developer Week!

Django, the open source web framework written in Python, has just hit the 1.0 milestone! My sincere congratulations to the entire Django team and community for all of their hard work.

Django (pronounced Jang-oh), like Ruby on Rails, is part of the new-hotness class of web frameworks that has generated interest amongst lots of web developers. Loosely following the model-view-controller paradigm, Django's goal is to create complex database-driven website quickly and efficiently. Pownce is powered by Django, as are parts of The Washington Post. Web developer Jeff Croft's was built using Django, and was actually what inspired me to give the framework a try.

I spent some time this summer playing with Django and was very impressed with its speed and efficiency and the community behind the project. The project released The Django Book online late last year and there are tons of great resources online for anyone wanting to give it a try.

You can download Django here, you just need Python 2.3 or higher.Read | Permalink | Email this | Comments

Alarm Clock est un plugin qui permet d’utiliser Rhythmbox comme un radio réveil. En utilisant ce plugin, vous pourrez vous réveiller avec la musique de votre choix, ou la radio ou n’importe flux sonore que Rhythmbox peut gérer.

Il est très facile à installer et il faut bien-sûr que Rhythmbox soit déjà installé sur votre système. Pour ce faire, vous allez ouvrir un Terminal et faites les actions suivantes :

1. Créer un dossier plugins avec la commande mkdir-p au cas ou ce répertoire existerai déjà :

mkdir -p $HOME/.gnome2/rhythmbox/plugins/

2. Rendez-vous dans le dossier que vous venons de créer :

cd $HOME/.gnome2/rhythmbox/plugins/

3. Pour terminer, téléchargez le pluginavec la commande suivante :

svn co http://nedrebo.org/svn/rhythmbox/alarm-clock

4. L’installation est terminée et vous pouvez maintenant ouvrir Rhytmbox.

Il est nécessaire de préciser que, pour que le plugin fonctionne, python 2.5 doit être installé.

Une fois Rhytmbox ouvert, vous devez aller dans le menu Edition>Greffons et activer le greffon Alam Clock. Ensuite, il ne vous reste plus qu’à programmer l’alarme et cela ce fait en allant dans le menu Outils.
