Launchpad in the Ubuntu Developer Week

Tuesday, January 20th, 2009

It’s Ubuntu Developer Week time again!

During this week, you can find a whole bunch of IRC sessions where members of the Ubuntu developer community introduce a topic — and take questions — that is of use to anyone wanting to get more deeply involved in Ubuntu development.

This time round, we’ve got the following Launchpad-related sessions:

Times are in UTC and you can find the sessions in #ubuntu-classroom on Freenode.

T-shirt competion results!

Tuesday, January 20th, 2009

Back in November we in the Launchpad team made our contribution to the sartorial health of the free software world: the Launchpad t-shirt!

As someone with a clue about fashion might say, the understated charcoal grey of the shirt provides the perfect background to the bright colours of the Launchpad logo. Walk into any conference wearing one of these and everyone will instantly see that you’re all about the colaboration.

But enough of the shilling: it’s time to announce the winners — that’s right, plural — of our Launchpad t-shirt competition! To stand a chance of winning one of our shirts, you had to answer this question:

What’s the average (mean) number of people per team in Launchpad?

Now, this was always going to be a moving target. Each day, people join Launchpad and people register new teams. So, the competition was more about finding a good way to work out the answer.

Before I go into who won, and why, I’d like to thank everyone who entered and also tell you what the answer is right now: 10.28. Here’s how we worked it out:

  1. add up all the active members of each Launchpad team
  2. divide the result by the number of active Launchpad teams.

An honourable mention must go to João Miguel Neves whose answer of 11 was the closest of all the guesses.

So, our winners are:

Congratulations! Launchpad t-shirts are on their way to you.

So, how did they do it?

Mark Lee

Mark was the first person to send us an answer using the Launchpad API:


from __future__ import division
from launchpadlib.launchpad import Launchpad, EDGE_SERVICE_ROOT

launchpad = Launchpad.get_token_and_login('Launchpad T-Shirt
competition', EDGE_SERVICE_ROOT, 'lp-cache')

team_len = 0
team_members = 0

for team in launchpad.people.findTeam(text=''):
   team_len += 1
   team_members += len(team.members)

print team_members / team_len

(Mark’s entry is licensed under the GPL version 3.)

Markus Korn

Markus had a similar idea:


LPMODE=STAGING ipython -p launchpad -c "x = [len(i.members) for i in launchpad.people.findTeam(text='')]; print float(sum(x))/len(x); print len(x); print sum(x)"

To run Markus’ solution, you’ll need to install ipython, bzr branch lp:~thekorn/+junk/ipython.launchpad.profile and then copy/link it to ~/.ipython

Markus noticed something odd when he was working on his entry: the number of teams the API returned was lower than the number reported on Launchpad’s people/teams page. Turns out it’s a bug in the API: launchpadlib’s findTeam only returns teams that have an email address set.

Get your Launchpad t-shirt

You can get hold of your own Launchpad t-shirt — men‘s and women‘s — over in the Canonical shop.

Congratulations to both Mark and Markus and thanks again to everyone who entered the competition 🙂

How we’re open sourcing Launchpad.

Friday, January 16th, 2009

Recently we announced that we’re open sourcing Launchpad, with a self-imposed deadline of 21 July 2009(22 June 2009 ed. note: we may push the date a bit, for testing purposes; it could be in August instead.)

Behind that announcement is a lot of activity. Obviously we’re not going to just throw the code over the wall and wish everyone good luck. The point of doing this is to bring the community that uses Launchpad.net into the development of Launchpad.net. There’s a philosophical reason for this: for a site whose primary purpose is to enable free software projects to collaborate, it’s natural that the users should be involved in improving the site itself.

But there’s a more practical reason, too.

One of my favorite metrics for judging a project’s success is to watch its bug tracker: the more bugs filed, and the faster the rate of new filings, the more successful the project is.

Those who don’t work in software sometimes express puzzlement at that metric: “What? How can more bugs be better?” But software developers know exactly what I mean: the rate of bug filing is proportional to the number of users, not to the number of actual bugs. (More precisely, it’s proportional to some combination of the number of users and their level of technical sophistication, since certain kinds of users are much more likely to file bugs than others.)

Well, I’ve been watching the Launchpad.net bug tracker for several weeks now, and judging by the bug-filing metric, Launchpad.net is very successful. Great. But what that means in practice is that we can’t resolve the majority of incoming bug reports and feature requests. The Launchpad development team at Canonical simply does not have enough surface area to handle it all. If we doubled — indeed, if we quadrupled — the size of the team, it still wouldn’t be enough. With a site like this, whose user base is large, and growing rapidly, there are really only two options:

  1. triage mercilessly, and leave most things undone
  2. open it up and let the users help

Clearly, answer 2 is better.

It implies some preparatory work on our part, however. We’re seeding the ground with developer documentation: this has already begun, though we’re still transferring over much of our internal documentation (remember, we have to go through everything and make sure we don’t accidentally open up any confidential business-related things — all this stuff was written by people who thought it was internal to the company at the time).

We also need to go through our dependencies and make sure we don’t have any license compatibility issues. The license on Launchpad will be the AGPLv3, but we still have to vet dependencies and work out any problems. By definition, this must happen before we release, so it’s work that Canonical must do internally.

Most importantly, we need to move our development discussion forums out into the open. Fortunately, most of Canonical’s Launchpad developers already have plenty of experence working in open source communities: they’re ready for this move, and we’re planning to do it before the code itself is opened (see the schedule), to minimize the number of simultaneous changes. We’ll also be publishing policies on how we’d like the community to work, and on how changes will be accepted back into the mainline and deployed on Launchpad.net. (The short answer is that Canonical decides, of course: we host the site, therefore we are responsible for the software that runs on it. The longer answer is that we want to make it easy for good changes to make it onto the site, and have some concrete plans for how to do that.)

In the near term, the next things you’ll see are more independent modules being opened up: code extracted from Launchpad and made into independent libraries for anyone to use (for example, Storm, LAZR.config, and LAZR.delegates).

And that’s all for now. Watch this space for more.

Notification of Launchpad Legal page changes

Tuesday, January 6th, 2009

Hi,

Today we have updated the Launchpad Legal page [1] with the following changes:

1) The Dev wiki [2] is now called out explicitly as having a CC content license.  Previously the Dev wiki proclaimed it was licensed under CC but was not listed on our Legal page.

2) The Content License section was updated for clarity. This was a housekeeping task and does not effect any Legal changes.

3) Future notifications of legal changes will be sent only to the Launchpad Announcement list [3].  Previously they were sent to the Launchpad Users list and News blog.

Joey

Preparing for signed PPAs

Wednesday, December 17th, 2008

Since we introduced PPAs, we’ve had a number of requests for signed packages in archives. Up until now, when installing a package from a PPA Ubuntu has warned that it is unsigned.

So, if you want to sign packages in a PPA, what do you sign them with? We dismissed two of the most obvious ideas:

  • signing with the author’s own key, as that’d mean either Launchpad storing their private key or doing away with the build part of PPAs and asking authors to upload binaries
  • signing with one key for all PPAs, which is a bit meaningless.

Instead, starting this week we’re generating a unique key for each archive and then signing each build made from the time of the key’s creation. As someone downloading from a PPA, you can easily check the fingerprint on its overview page in Launchpad to ensure you’re getting what you expect.

It’ll take a while to generate all the keys; check your PPA overview page to see if your key is ready yet. In the mean time, some PPAs will have keys and others will continue to generate warnings about unsigned packages.

We’ll post more details in the new year.

Launchpad now on Twitter and identi.ca!

Thursday, December 11th, 2008

You can now follow Launchpad news and other updates through Twitter and identi.ca!

For news and status updates, take a look at:

Brad‘s also running an experiment using TwitterFeed to give us:

TwitterFeeds takes the Atom feed of all bug reported against the Launchpad project and turns it into a stream of microblog posts.

Putting your project’s bugs into identi.ca or Twitter

If you track your project’s bugs in Launchpad, you can also turn them into an indeti.ca or Twitter stream. Similarly, you can create a stream of your project’s code branches, latest revisions or announcements!

Here’s what you need to do:

Step 1: Create an identi.ca or Twitter account — something like yourprojectbugs.

Step 2: Visit your project’s overview page in Launchpad and copy the relevant Atom feed URL.

Getting the Atom feed address

Step 3: Log into TwitterFeed using your OpenID.

Step 4: Give TwitterFeed the Atom feed and your identi.ca or Twitter account details.

And you’re done!

Let us know how you find our first steps in microblogging Launchpad.

Update: The instructions above now cover using TwitterFeed with laconi.ca based services, such as identi.ca. It’s also worth noting that TwitterFeed supports a maximum of five updates every 30 mins so this may not be ideal if you want to ensure you get comprehensive coverage.

Get in touch with any other Launchpad user

Wednesday, November 19th, 2008

Contact this userNeed to contact someone who’s hidden their email address in Launchpad?

No problem. Launchpad profile pages now give you a way to contact that person without having to know their email address.

Over to Barry Warsaw — who worked on the feature — for more:

You can now contact up to three other Launchpad users per day, even if those users have hidden their email addresses. The recipient’s privacy is preserved (unless they respond) and you can choose which of your valid email addresses the contact message will come from.

So now you can get in touch with all prospective new team members, bug commenters, branch owners and so on.

Try it out on your own profile page.

Threaded development – Launchpad t-shirts

Wednesday, November 19th, 2008

Launchpad t-shirts for men and womenAt our recent get-together in London, we in the Launchpad team discovered a sure-fire way to turn heads: t-shirts emblazoned with the stylish new Launchpad logo.

Naturally, we want to share this milestone in sartorial expression with everyone who loves Launchpad. So, you can now buy your own Launchpad t-shirt from the Canonical store (women’s and men’s versions available).

We’re also giving one away in our competition. To enter, answer this question correctly:

What’s the average (mean) number of people per team in Launchpad?

Send your answer and UK t-shirt size (S, M, L, XL or XXL for men, XS, S, M, L or XL for women) to feedback@launchpad.net, with the subject line “T-shirt competition”, before Friday 12th December. The Launchpad team will select the winner from the correct answers.

The Launchpad team’s decision is final and we’ll need the winner’s postal address to send the t-shirt.

Good luck 🙂

Update: As more people join and register projects in Launchpad, the correct answer may vary a little.

A cool bunch of individuals

Friday, October 24th, 2008

What do you get when you bring together a group of developers, QA engineers and other Launchpad team members? Cheesy photos, of course!

The Launchpad team in London

We’ve come by air and by land to meet in London for a couple of weeks at what we’re calling the Launchpad EPIC. It’s a rare chance to get the full Launchpad team together for planning, training and, of course, unrepentantly bad dancing.

It also means we’re in town at the same time as the London Ubuntu 8.10 release party. If you’re planning to be there, come say “hello”.

Launchpad 2.1.10 – faster branch uploads

Thursday, October 16th, 2008

The Launchpad team is excited to announce the October 16th 2008 release of Launchpad 2.1.10!

There’s great news if you use Launchpad to host Bazaar branches, plus there’s the usual smaller new features and bug fixes.

Slashing branch upload times

From now on, you may notice that uploading a branch to Launchpad is significantly quicker. With this release, we’ve introduced support for Bazaar’s new stacked branches feature.

Over to Launchpad Code developer, Jono Lange, for details:

Stacked branches work just like normal branches but hold only the history that differentiates them from the project’s mainline.

So, if you upload a branch to a project that already has its trunk branch in Launchpad, you’re uploading only the differences between your work and the trunk.

Stacked branches mean that uploading a large project’s code to Launchpad can now take just a couple of minutes. To use them, you need to upgrade your branches to Bazaar format 1.6 and run Bazaar 1.7 or later.

See Jono’s blog post for more detail.

This bug affects me too

If you’ve ever come to file a bug and found that it’s already been reported, you may have wanted to let the project know that you too have been affected.

Trouble is: many projects find “me too” comments unhelpful because they don’t add much to the discussion.

Launchpad’s new “This bug affects me too” feature lets you record just that but without the guilt! Give it a go in our staging environment.

We’ll use the “me too” data in future to help projects identify hot bugs.

Also in Launchpad 2.1.10

You can find the full details of this release on its milestone page.

Getting help with Launchpad

Each weekday, members of the Launchpad team are taking turns to offer help with Launchpad. Check the #launchpad channel topic or our wiki page to see who’s on duty.

And finally…

Launchpad 2.1.11 is due on the 19th November. In the mean time, join us in #launchpad on Freenode and on the launchpad-users mailing list.

If you come across any bugs in Launchpad, please report them!
