I’ll make it quick so I can go back to watching TV:

Announcing my first attempt at a generic Django Developer Kit, a CentOS (powered by rPath’s conary) based software appliance with all you’d need to run a Django project.

Django Developer Kit Appliance

The current images are built on the development stage, which means it includes the very latest Django 1.2 code line straight from the subversion repository. Currently, the following packages make up the base appliance:

• django
• django-ajax-selects
• django-authority
• django-cache-memcached
• django-contact-form
• django-db-postgres
• django-filter
• django-notification
• django-pagination
• django-piston
• django-profile
• django-sorting
• django-tagging
• django-threadedcomments
• file
• gettext
• httpd
• less
• mod_python
• mod_ssl
• mod_wsgi
• mx
• openssh-clients
• openssh-server
• openssl
• PIL
• postgresql-server
• psycopg2
• python-ctypes
• python-markdown
• python-memcached
• python-urlgrabber
• PyYAML
• scgi
• sendmail
• south
• sqlite
• sudo
• tar
• vim-enhanced

I’m still working out the kinks and have decided to not include openssl by default until I have a generic way of generating a certificate for the appliance. I will also be adding tools such as git, mercurial, etc so that people can use the appliance as a testing lab/environment for their own projects.

Once you’ve either installed the appliance or launched on EC2 or ESX, make sure to visit your appliance’s htts://IP:8003 address to configure the administrative interface (log in as admin with password as your password). Then click the Updates plugin to get updates as I will be making changes between now and the time I publish this post.

Download it today!

Just wanted to update everyone who showed interest in the new release of GNOME Developer Kit I announced yesterday. Based on some preliminary statistics I collected in the (less than) last 24 hours, it seems that the VMware image type got the most download, followed closely by the installable ISO format. I guess that was due to VirtualBox being able to use *.vmdk files and some people opting for the free virtualization tool.

Here are the preliminary results so far:

1. VMware image: 42 downloads
2. Installable ISO: 26 downloads
3. RAW filesystem image: 17 downloads

About GNOME 2.29.92

Due to the number of downloads and and comments I received, I felt that I should provide with some background on how to install/remove packages and update your system using the conary package management system. So here you go:

The package management system behind the GNOME Developer Kit is called conary and is considered by many as the next generation package management system when compared to some of the popular options out there. One of the reasons behind this claim is the fact that your entire system is actually completely maintained in a versioned state, and conary is always “aware” of what is installed on your system and what files and dependencies make up the entire “set”. This allows for some pretty nifty operations such as rolling back to a specific state of your system.

In order to check for new updates for your system, open a terminal and run the command sudo conary updateall. conary will then check for updates and prompt you to accept the update or not. Please keep in mind that the first time you run conary for the first time, you will experience a delay as your entire system gets analyzed in preparation for the changes that are to take place. All subsequent actions performed will be much faster, I promise. If after a while you don’t feel like waiting for the prompt, add –no-interactive to the update command to have your system updated automatically.

Now, let’s just say that you decided to install something new, such as Banshee. Easy, just run sudo conary update banshee (remember to add –no-interactive for no-hands updates) and voilá!

Want to know what was actually installed on your system? conary q banshee will tell you what version of banshee was installed. How about what files were installed? conary q –ls banshee will give you a list of all the files that were installed and conary q –lsl banshee will give you the long list with file permissions and modes.

Changed your mind and want to remove banshee from your system? sudo conary erase banshee will take care of that. Want to actually roll your system back to the state it was before you installed banshee instead? sudo conary rollback 1 will rollback your system exactly one transaction. Want to go further back? Just increase that number to represent how many transactions to roll back. Want to rollback but don’t remember what point in time you want to go? sudo conary rblist will display a list of all transactions and what was changed. Note that each transaction is preceded by the letter “r“, so if you want to rollback to the point r.15, then use sudo conary rollback r.15 (and don’t forget that “r” or you’ll rollback exactly 15 transactions instead).

How about searching for a package? If it is something that it is already installed on your system, then conary q [package name] will give you the information you want. If the package is not installed on your system yet, then conary rq [package name] is what you need, though since conary does not yet make use of metadata, you’ll need to know the exact name of what you’re looking for. Now, let’s say you want to find out what package provides the command /sbin/service? Use conary q –path /sbin/service to find out that initscripts:runtime=8.81.2-0.11-1 is responsible for providing it (use rq if you want to search the remote repository).

Well, I think this is enough to get you going. You’ll probably want to install Flash and media codecs to enjoy browsing some sites and listening to your media, so let’s apply what we’ve learned so far and run: sudo conary update flashplayer group-codecs

If you’ve stayed with me until now, you may want to read up on what else conary can do or even consider packaging for GNOME Developer Kit. Your help will be greatly appreciated!

UPDATE: Thanks Alberto Ruiz for pointing out that VirtualBox can use .vmdk files, so the VMware image can be used for that purpose.

Thanks to the incredible work of Zhang “Jesse” Sen and Vladimir Melo, a brand new release of the GNOME Developer Kit has been published! “What’s new”, you may ask? Everything, since all packages are built directly from git.gnome.org! But that alone is not what makes this release so cool, but the fact that the final image went through a dramatic “diet”, shedding a lot of its “weight” and going from a 1.4GB monster to less than 700MB of pure GNOME goodness!!!

From Screenshots

Firefox was replaced by Epiphany and codecs and fancy-Nancy stuff was scrapped to make room for a lightweight release for developers and translators!

So go ahead and try the new images today:

• x86  VMware (R) Virtual Appliance 636 MB, SHA1: 4b4266fc1a65189d65efd7f3ac51797396babf78
• x86  Appliance Installable ISO 697 MB, SHA1: c3345cadae9c7338d0b92ba0ad1a187930652357
• x86  Parallels, QEMU (Raw Hard Disk) 644 MB, SHA1: e3dbbff4e65f8e086f422885a24d8ee04bc89f44

Python Testing: Beginner's Guide

I was looking for some material on proper python testing in order to improve my QA skills and after some “Googling” came across “Python Testing: Beginner’s Guide“. My first impulse was to hit Amazon and see if they had it and if I could buy an ebook version. Sadly, they only had the “dead tree” version, so I decided to check if the publisher, PackT Publishing, had an alternative.

Boy, was I glad I hit their web site! Not only there was an ebook version of that book, but they do not password protect them, giving you complete control over your purchase!!! You can also copy text from it, which makes your life really easy when you’re following along and want to copy some of the code being described!

Needless to say I purchased the ebook version and have already allocated my weekend to read it, so you can expect a review next week. In the meantime, here’s a free chapter (PDF) for you to get a taste for the book: Chapter 5: When Doctest isn’t Enough: Unittest to the Rescue

Following the tradition of releasing simultaneously with the Transifex project, I’m pleased to present you the Transifex “Magneto” Appliance 0.8! There are just too many cool features to mention here… so I won’t! Just go ahead and read the release notes instead.

From Transifex v8.0 featutes

As far as the appliance goes, the most important thing to know is that I dropped MySQL and replaced it with Postgresql, so if you’re thinking of updating an existing deployment, you’ll have to backup your data and handle the restoration process. If you’re installing for the first time, choose from the following image types:

• Installable ISO (x86)
• Installable ISO (x86_64)
• VMware (x86)
• VMware (x86_64)
• Amazon EC2 Small (ami-af8669c6)
• Amazon EC2 Large (ami-b7a54ade)

The appliance is pre-configured with 2 unique users: editor and guest (with passwords editor and guest respectively) and several projects for you to play!  To keep it up to date, log in to the web based administrative interface by connecting to your appliances url using https and adding port 8003 at the end. Then, login as admin (the initial password is password but you’ll be prompted to change it during the initial wizard). I can proudly say that the Transifex Appliance has been downloaded several hundred times in the last 2 months and is currently being used by several companies and projects that are either test driving Transifex or decided to host their own instance like the Xfce project for their translations!

As always the development branch of the appliance will follow the development code line of Transifex and provide a playground for anyone who wants to help out the project, such as the tasks created ahead of the upcoming Google Summer of Code. Download the appliance today and see why projects such as Meego, LXDE, Xfce, Fedora, and many more chose Transifex to manage their translations!

With the GNOME 2.30 release just around the corner, translators are feverishly working hard to get the desktop completely translated into a multitude of different languages! But unless you’re comfortable building the application you’re trying to translate on your own (or perhaps the entire desktop), you’re pretty much doing what I call “blind translations.”

From Screenshots

The good news is that you don’t have to do any compiling to play with the very latest GNOME applications! Just download the GNOME Developer Kit and start translating knowing that you can actually see what you’re translating!

Borrowing from a previous post I wrote, just what is the GNOME Developer Kit? It is a continuous build of GNOME packages all bundled up into a distribution (in this case, Foresight Linux) and distributed in a few different formats that you can either install or run in a virtual environmen.

So if you’re a translator or writing docs, imagine being able to see the application you’re trying to translate running right in front of you! As the GNOME Developer’s Kit already comes with a lot of tools such as gettext, intltool and poEdit, you got your work cut out for you!

So don’t just sit there! Go download your GNOME Developer Kit today!

Yesterday I attended my first TriZPUG meeting to check out Kurt Grandis‘ talk on Fabric, “a Python library and command-line tool for streamlining the use of SSH for application deployment or systems administration tasks.”

It was pretty cool to see a bunch of guys who share the same interests take some time on a Thursday to hang out, drink beers, and chat about python, django, zope, and other stuff. After the original talk was over and some of the other lightening talks that succeeded it was over, a couple of things became very clear to me:

• There was a real need to make it easier for system administrators and OPS people to handle the difficult task of deploying and maintaining systems, cloud or not;
• Some of the tools and/or tool implementations presented were being used in an attempt to minimize this pain, but you were still pretty much had no control over what made its way to the systems in the end of the process;

Having been using rBuilder Online to manage and maintain my Transifex Appliance, and being somewhat “spoiled” with the ability of having fine grained control over the entire software stack and having the option of deploying my final “product” on several different cloud environments, I couldn’t help but offer to speak a bit about my experience. I sure hope my impromptu presentation didn’t come across as being “just a sell’s pitch” and I definitely tried my best not to sound like I was selling something. I truly feel that the technology developed here at rPath can solve many of the typical issues that people have getting their product through the many different life cycles and eventually out the door and into the hands of their customers!

Today I started going through Fabric’s documentation and am already making plans to include it in some of the test automation tools we’re developing here!

Anyhow, after my presentation there was a quick intro to epdb, the “Extended Python Debugger”, a very cool python debugger developed by an ex-rPathian and something I use on a daily basis! Turns out that the epdb currently packaged for Foresight Linux was outdated, so I spent a few minutes during my lunch today to update it. If you’re running Foresight, just run conary update epdb=:2-devel or wait for it to make its way to the stable label. If you’ve never heard of epdb, I strongly suggest you give it a try!

Just wanted to tease you guys out there about a new feature that the Transifex guys are working on these days: Translation Reviews! Have you ever wandered if your translations conform to the standard vocabulary that your team uses? Have you ever wanted someone to take a look at what you’ve done before sending in your final work for commit approval?

From Transifex v8.0 featutes

Now, mind you this is still very alpha code but that is probably a good thing since you can play with it and give your feedback on how to improve it. As always, you can get this in an easy to consume format by using the Transifex Appliance Developer edition… or you can join the Xfce translators who are already enjoying Transifex latest code!

In case you’ve missed it, the Xfce project has been using their own installation of Transifex to manage their translations online! Translators can now visit http://translations.xfce.org and keep up with the action!

From Transifex v8.0 featutes

I’ve been contributing with translations for the Brazilian Portuguese language for quite some time now, and have been a strong supporter for the Transifex project as well, so I was thrilled to learn they were “working together”! But there is a second reason why I’m mentioning this on my blog:
