Launchpad is kinda hard to describe. When I’m asked what it is, I normally use three or more of the words “open source free software support project Q&A code registration bugs management listing bazaar planning hosting”. Most people make comparisons to Sourceforge, Savannah, Berlios and Google code hosting, and while those are useful, it’s only a part of the picture. The other part, which is perhaps not as well understood, is that it’s also a public project registration service, similar to Freshmeat. Well, except for a twist.
In addition to providing a project registration service open to the public for free (with probably the best Google juice out there; this has caught some people off-guard before!), Launchpad takes this to a next step, and actually provides a unified interface for interacting with each project registered. The most obvious unified service that you can use today is our code directory, which I want to introduce here.
Now Launchpad provides some key features related to source code for free software projects:
There’s a really cool thing that falls out of the combination of code imports, branch mirrors and Bazaar: you can use bzr and Launchpad to fetch any piece of software we have registered code for. And Bazaar even provides a little shortcut that makes it even easier to grab the default branch for any project: bzr branch lp:<projectname>.
The effect is that you can, right now, pull a /lot/ of software in less than 30 keystrokes, without knowing or caring about what its native version-control system is, or where it’s hosted. Want to grab the Python source code? Just do bzr branch lp:python. How about Storm? bzr branch lp:storm. In fact, there are thousands of native Bazaar branches and over one thousand imported branches. Here are just a few examples of major projects you can pull right now:
bzr branch lp:railsbzr branch lp:blenderbzr branch lp:f-spotbzr branch lp:grubbzr branch lp:twistedbzr branch lp:bzrbzr branch lp:gccCouldn’t find a branch listed for the project you want? We can sort this out for you, too. If it’s in CVS or Subversion elsewhere, you can just follow the instructions for setting up an import. If it’s a Bazaar branch, just register it and we’ll hook it up with the project’s mainline series record.
If you visit https://code.launchpad.net/ you’ll notice that it has an abbreviated project cloud, which lists all the projects with branches in Launchpad. The project’s name is rendered in different sizes and intensities according to how active the actual project is; the size of the name in the cloud is defined by the number of branches that the project has, and the intensity of the tag in the cloud is determined by how recent the last commit to any active branch is. And green indicates that there’s a default branch for the project, which means that the bzr branch lp:foo abbreviation works for it. There’s a also a page with the full code cloud.
So each of those projects has active source code branches that you can pull from Launchpad using Bazaar. For instance, to check the source code for Apport, you could click on its entry in the listing and getting there you could inspect the branches available and select one of them for pulling. For instance, if you chose Will Woods’ Fedora support branch you get instructions on how to pull it: bzr branch http://bazaar.launchpad.net/~wwoods/apport/fedora or even just
bzr branch lp:~wwoods/apport/fedora
Import requests are handled in a queue by Launchpad code ninjas; normally this it Michael Hudson’s responsibility but starting today I’ll be helping out too. Of the import requests I handled today, the following succeeded and are ready for grabbing in the great bzr-get-lp-colon fashion:
bzr branch lp:gtk-qt-enginebzr branch lp:lshwbzr branch lp:tsclientbzr branch lp:dohickeybzr branch lp:meshlabbzr branch lp:rasmolI’ll keep you posted on new imports as they come online. Meanwhile, go grab some branches and post some comments telling me what you think. If you have any problems or questions about our code hosting service, feel free to ask on the Launchpad code section in answers.launchpad.net.
You could argue that the free software world isn’t short of a text editor or two. With some people already pretty attached to their preferred choice, you might wonder if we really need another.
Some time ago, I read a newspaper article complaining that today’s computer desktop dangles too many distractions in front of professional writers. The author presented two solutions:
WriteRoom is a big black box with green text. Basically, think Windows Notepad but with fancier marketing and a $24.95 price tag. Nonetheless, its simplicity has struck a chord with many; not least of all me.
That’s why I was delighted when Bruno Bord told me about PyRoom. It’s one of several WriteRoom clones that grew out of a thread on the Ubuntu forums and, as you might expect, is written in Python.
If you have Bazaar, you can get hold of PyRoom with:
bzr branch http://bazaar.launchpad.net/~brunobord/pyroom/trunk
Writing this post in PyRoom almost makes me nostalgic for my Amstrad PCW days. It’s is a work in progress so give it a try and file bug reports. Bruno’s also on the look-out for translators.
30th January 17.00 UTC in #launchpad
Launchpad isn’t just about source code, bugs, or translations. Nor packages, specifications, community support or file downloads.
Launchpad’s about people. Okay, that sounds a bit cheesy but it’s true: every new feature or improvement we make to Launchpad is designed to make it easier for you, me and anyone else to work together.
That’s why we hold monthly user meetings: talking to people who use Launchpad is absolutely the best way to find out what we can improve and what works well. You can find the Launchpad team in #launchpad and on the launchpad-users list just about any time but these meetings give you a focused opportunity to talk directly to members of the Launchpad team.
Come along to this month’s meeting on 30th January at 17.00 UTC in #launchpad on Freenode. Add your question or any other item to the agenda or simply speak up during the meeting. See you there 🙂
Over the past couple of weeks we’ve been accepting entries to our Launchpad logo competition.
Rather than store up the entries until the deadline (31st March, by the way), I thought I’d share a couple of those we’ve had so far. Of course, you don’t have to wait for me to pop up here to see what people are submitting. If you want to get an email whenever a new logo is put forward, click Subscribe on the submissions page.
I like the flow of Damián Vila’s design, which maintains a green feel similar to the present Launchpad site design. The rocket flying off from the Launchpad logo-text puts me in mind of Launchpad as just that – a launching point for work on free software projects.
Donn Ingle says he “tried to capture the fun spirit of the overall Launchpad design”. His is the first logo to move away from green and I think he does capture a sense of fun in his design. I’d love to see an animated version.
Do go see the other entries in the competition. Better still, fire up Inkscape and create your own!
This post doesn’t imply any particular favourites, by the way 🙂

Another part of the Zope project – the Zope Content Management Framework (CMF) – has joined both Zope 2 and Zope 3 in using Launchpad to track bugs, making it much easier for all three to work together on common bugs.
Similarly, Soren Hansen is now using Launchpad to track bugs and host code for LibMMS, a library for connecting to Window Media streams. He told me why he wanted to host the code in Launchpad:
“I have a couple of other projects on Launchpad that I pretty much just put there to share them with co-workers and such, but out of nowhere, branches popped up with new features from people I’ve never talked to (neither before nor since).
“It’s really distributed revision system at it’s best. One of the things that could have gone wrong when people started adopting distributed version control was that changes would never flow back upstream. Adding Launchpad to the workflow makes it all come together naturally.”
The community behind Inkscape – the free software vector drawing tool – have chosen Launchpad as their new bug tracker!
Bryce Harrington, one of the project’s founders, explained why:
“The Inkscape project is gearing up for our next coming release, and based on our experience doing the past release, our current bug tracking system is really not up to the task of managing a large number of bugs.
“Launchpad has all the usual advanced bug management capabilities that we need. We’re also looking forward to making good use of the external bug tracker linking for keeping a watch on key bug reports in Cairo, Gtk, and other projects we depend on.”
Launchpad developer James Henstridge is working with the Inkscape team over the next few days to import their bug history from Sourceforge. If you’re interested in switching your project’s bug tracking to Launchpad – with complete bug history – drop us a mail to feedback@launchpad.net.
If you’re new to Launchpad, next week is a great time to find out more!
My Launchpad colleagues and I will be leading a number of IRC tutorial sessions designed to give an introduction to Launchpad and its applications. Here’s what’s on and when:
These sessions are as part of Ubuntu Open Week and so will be in Freenode’s #ubuntu-classroom channel.
If you have any particular requests or suggestions for any of these suggestions, please leave a comment!
If you’re a web developer, you’ve almost certainly heard of Zope.
If you’re not familiar with Zope, here’s a quick overview. It’s a free software web application framework that comes in two flavours: Zope 2 and Zope3. The Plone and Silva content management systems use it as their base, as do several high profile websites. Our very own Launchpad makes heavy use of Zope 3.
Earlier this year the Zope 3 project (a “next generation Zope” team) adopted Launchpad for bug tracking. Now the main Zope 2 project is moving to Launchpad as well. Jim Fulton, CTO of the Zope Corporation, explained why:
“Launchpad works great and, with its many project support tools, allows us to focus on creating a great Zope platform without being distracted by developing our own project-management tools.”
The Launchpad team have helped the Zope project to move all their bug history to Launchpad, allowing them to pick up exactly where they left off. I asked Jim how smoothly the move went for Zope 3:
“Very. The Launchpad team took a custom data export format from us and imported it into Launchpad with great fidelity, keeping old issues readily accessible.”
So, other than enabling the Zope guys to do away with the burden of running their own bug tracking tool, what else does Launchpad offer them? Andreas Jung, also of Zope, explained that “managing Zope 2 and Zope 3 bugs together on LP makes sense since Zope 2 includes large parts of the Zope 3 core”.
Launchpad’s ability to track how the same bug affects different communities and projects is ideally suited to this situation.
Now, if the Zope 3 team find that one of the bugs they’re tracking also affects Zope 2, they can push that bug to Zope 2’s bug list. From that point, the bug and its comment history are shared between the two projects, while retaining separate statuses and importance levels.
I’d like to give a warm welcome to Zope 2 on behalf of the Launchpad team. If you’d like more information on using Launchpad for your project, email us or join us in #launchpad on Freenode.
Update: The Zope Content Management Framework now also uses Launchpad to track its bugs!
