Mer is back : Please visit to learn more about this news.


We employ the sprints method as development method for Mer. That means, get yourself a account, and read this document through if you would like to contribute :)


[edit] How do I participate in Mer?

Download the latest release of Mer and help with testing it out. Check the current open tasks, blueprints and proposals, and see if there's something you'd like to dig your teeth into.

[edit] About Mer Software Packages

The foundations of Mer are primarily based on Ubuntu 9.04 (or Debian Lenny); then the open Maemo software from Nokia is overlaid and finally Mer specific patches are applied.

There is a table of all the Mer Packages.

[edit] How to be a Mer contributor

Most Mer development talk goes on in #mer on - here's some info on connecting and a web client.

We use microblogging for keeping each other aware of activities (do sign up for this if you haven't already after signing up for Mer work.

[edit] How to develop for Mer

In order to begin developing in Mer see Mer/Build. This covers both developing applications to run on Mer and developing the Mer system.

Definitely read the procedures below on how to do Mer work.

[edit] Layout

The current method of sprints is:

  • Sprints run for 4 weeks at a time, where after 3 weeks the current progress in the Testing repository will be made into testing images and non-bug-fixes uploads to Testing are forbidden (feature freeze - work can still be done in Devel repository). After sprint completion, final images are built and release post posted along with achievements of the sprint.

Everything is posted on

[edit] Routine for Mer contributors

Mer contributor procedure:

  • When you have free time to spare
    • Read current sprint page and see if there are any tasks in product backlog you would like to take on and you are capable of
      • If yes, click the arrow icon
      • Go to Procedure for performing task X
    • Follow mer-chatter and see if there are any new tasks coming up you would like to take on
      • If yes, if so, find it on the sprint page and click the arrow icon
      • Go to Procedure for performing task X
    • If you have an idea for a task to be done, contact the mentor in charge of the area & and after agreement, add it to product backlog

Procedure for performing task X:

  • When you have chosen to perform a task X, you are initially given a time slot of 2 days to do it. If you need to extend beyond this, there's a button to extend +2 days. If the task is not actively extended, it will show as red (expired) and your mentor might drop your ownership of it.
  • While performing task X, you can always talk with your mentor about specifics
  • While performing task X, log to mer-chatter (see Awareness) what is happening with it, and update the sprint item regarding how far in % you are with it (The edit button)
  • When done, mark it as done on the sprint page, and indicate on mer-chatter that you finished doing it

No-one is going to assign you specific tasks and you take on the tasks by your own initiative - so a mentor is not as such your boss, but more of a helper to help you get your task done. You pitch in with what you'd like to contribute with.

[edit] Routine for Mer mentors

  • When you have free time to spare:
      • Monitor your area / the tasks you are mentoring and take action if it's not being handled properly (it will show as red if it's not extended)
    • When getting contacted about a possible task
      • Add it to your area in the sprint backlog on the sprint page if it is reasonable
    • Help out as you can with guidance for the contributors if they contact you about how to go about a task.
    • Develop your area - add new tasks to backlog when they come up and work with the other mentors to decide direction of Mer in general
    • Add incoming bug reports as tasks to backlog to be looked into in your sprint page.
  • Before each sprint, check the blueprints page and see if there is a task which you wouild like to do during the next sprint
