Developer Week: Summary Day 3

It’s sad news, yes – Ubuntu Developer Week for the 12.04 cycle is over. It’s been three fantastic days full of action-packed sessions. If you couldn’t attend, check out the logs of the sessions, all of them are posted on the UDW page.

Here’s what happened on day 3, yesterday:

  1. Fixing Desktop bugsseb128Sébastien Bacher kicked off our last day. At first he took some time to explain how the Desktop team works and how they go about fixing bugs, then he took a quite recent example and explained how to work all the individual packaging bits to fix a Desktop bug in Ubuntu. For bonus points he explained how to get Wanda the Fish working in Ubuntu.
  2. Triaging Desktop bugsom26erNext up was Omer Akram, who first gave us an update about his personal life, then quickly dived into triaging bugs. He explained all the actors involved, what to bear in mind and general things to make sure when you are reviewing bug reports. Omer, who started out by triaging bugs himself, did a great job explaining how to get involved and why it’s so important.
  3. Simple Lenses with Singletmhall119Michael Hall, an unstoppable force throughout UDW, provided a great session about how to write lenses for Unity using Singlet. For developers who have used Python in the past, this might be an even easier (and more pythonic way) to interact with Unity and Desktop bits.
  4. Building locally with pbuildertumbleweed
    Those of you venturing into the land of Ubuntu development will have to deal with packaging and it’s good to do it in a safe, clean and reproducible manner. Stefano Rivera explained a lot of options for doing that including some advanced features useful if you want to debug builds. Great work.
  5. Writing Crisp Changelogscoolbhavi
    Again for those of you interested in package maintenance: it’s important to document your work properly. You don’t want anybody (including yourself) having to go back in a few months or years and dive into the archaelogy of a package to understand what exactly was changed and why. Bhavani Shankar shared his experience in writing crisp changelog entries.
  6. Getting started with contributing to Ubuntu Documentationjbicha
    The Ubuntu Documentation project is of vital importance to everyone who is new to Ubuntu. Also is it a great way to get involved with Ubuntu, as Jeremy Bicha showed. He explained how to the team works generally and how to actually go and contribute improvements.
  7. Adding Ubuntu One to your applicationsaquarius
    If you want to allow you application to sync data to the internet, it never was easier. Stuart Langridge showed and explained some easy examples which demoed how to tie in Ubuntu One services into your app.
  8. Pair Programming and Code Review in the Cloud!kirkland
    Dustin Kirkland did an impressive live demo of how to use EC2 to do pair programming, review of code and builds. He used tmux and byobu and explained in detail how to drive the infrastructure. Unfortunately the log is a bit colourless without the live demo right next to it.
  9. Syncing your app data everywhere with U1DBaquarius
    Nothing stops Stuart Langridge when he’s on a roll. He delivered his second session all about the new Ubuntu One Database. For those of you new to the initiative: “U1DB is for syncing data — that is, something structured — to every device you want”. The session is short, has lots of good information in it and a nice example of how to work with it.
  10. Automated packaging with pkgmejames_w
    James Westby gave a great introduction to the pkgme project he has been working on and it’s fantastic to see that a lot of repetitive tasks are done by a tool. It was nice to see pkgme package itself. Give it a whirl and let James know how it works out for you.
  11. Fixing internationalisation bugskelemengabor
    Gábor Kelemen is one of the heroes of Ubuntu’s internationalisation. Keeping all packages translatable and translations in shape matters deeply to him and he gave a nice overview over how common problems can easily be resolved. Köszönöm Gábor!
  12. How to fix small bugs in Ubuntuwarp10
    Andrea Colangelo took over and quickly ran us through a couple of examples of fixed bugs and explained how exactly they were fixed. By the end of the session it was clear that in a lot of cases it’s no rocket science to go and fix a bug. Grazie mille, Andrea – I hope many will find your session as encouraging as we did.
  13. Problem Lifecycle in Ubuntucprofitt
    Charles Profitt delivered the last session of the event and explained how all teams in Ubuntu work together to go from problem to solution, involving the lifecycle of a bug report, which was a big enough topic on its own already. Throughout the session he showed how you can join each of the teams and make a difference. Awesome!

What a fantastic day. Thanks a lot to all the speakers who made this Ubuntu Developer Week possible. Thanks a lot to everyone who attended as well. It was great to see a lot of interaction, questions and interest. Until next time! 🙂

Developer Week: Summary Day 2, Outlook Day 3

Day 2 of Ubuntu Developer Week is over and it was awesome! Logs up are up at the UDW page, so go and check them out if you couldn’t make it yesterday.

Let’s take a look at what happened yesterday:

  1. Bringing your app to Ubuntudpm
    David Planella kicked of day 2 and gave a well-structured session about how to get your app into Ubuntu and managed to answer heaps and heaps of questions. If you missed the session, make sure you go back and read the log.
  2. How to update a package to the latest upstream version in the repositoriescoolbhavi
    Bhavani Shankar gave an excellent session about how to take an actual source package from Ubuntu and update it to a newer upstream release. He placed great importance on all the pitfalls and explained how to make sure it gets reviewed by our Ubuntu sponsors.
  3. Ubuntu Technology overviewmhall119
    Indicators, lenses, scopes, APIs, Michael Hall got the best out of half an hour by explaining everything to tightly integrate your app or code in general with Ubuntu technologies. Great work.
  4. Charming Jujum_3
    Mark Mims was up next and talked about juju, a great way to deploy services in all kinds of scenarios.

  5. Running the development releaseEffenberg0x0 & Cariboo907

    If you always wanted to take a peek at the new development release but were afraid to do it, check out this great session by our dynamic duo Alvaro Leal and Jim Kielman. They quickly went through all the available options to do this in a safe manner, answered questions and mentioned this as a great way to play around with the new development release, to test it or to develop on it.

  6. Working with Debiantumbleweed

    Ubuntu is based on Debian and has a great relationship with it. Stefano Rivera took great care to explain why it is important we work closely, how to work with Debian maintainers and also where differences in the chosen infrastructure are. I was very pleased to see how much interest was in the session.

  7. Ubuntu Distributed Developmentbarry

    Bazaar and Ubuntu Distributed Development have come a very way and nowadays make many many packaging and package maintenance tasks a lot easier. Barry Warsaw has been working closely with the Launchpad and Bazaar team, so he did a great job explaining how it all works and demo with a few examples how you can make use of it and how it can make your life easier.

  8. Working in DebianLaney

    Iain Lane basically started where Stefano Rivera’s session stopped earlier and talked about how to get things done in Debian. He showed how Debian’s instrastructure is used and who to talk to if you might ever get stuck. Awesome!

  9. Starting with HTML/CSSbenonsoftware
    We mentioned it earlier already: Ben Donald-Wilson not only gave the session at 7:30 in the morning, but also on his birthday! We couldn’t find out if he had a long party before the session, but in any case it was an excellent session. With a small example he explained basics of HTML and CSS use. A great introduction who are new to the topic. Thanks again and happy birthday Ben!
  10. Fixing small bugs in UnityTrevinho and andyrock

    Italy took over the last session of the day and it was Marco Trevisan and Andrea Azzarone who brought a great introduction into making Unity even more awesome.
