The Mission of KDE’s Wikis

KDE has three wikis: TechBase, Community and UserBase. The separation has the following meaning according to http://wiki.kde.org:

  • TechBase: The primary place for high quality technical information about KDE targeted at 3rd party developers, ISVs and system administrators.
  • Community: The working area for the KDE community. It provides a place for sharing information within the community and coordinating community teams.
  • UserBase: The home for KDE users and enthusiasts. It provides high quality information for end users on how to use KDE applications.

So TechBase is a source of mostly technical information. This includes step-by-step howtos for all sorts of KDE development as well as the feature plans and schedules for KDE releases and so forth. It’s mainly static content. Think of a howto for a Plasma Widget or a howto for building KDE. The content usually is valid for a long time, mostly even for years. For those of you longer in the KDE project, TechBase is the same as our good old developer.kde.org page (and we’ve never put arbitrary content there). The only difference is, that it’s now maintained as wiki.

UserBase is the same thing for users. It provides information about tips and tricks for KDE application, links to further pages an so on. It’s also rather static content. This is also why TechBase and UserBase both feature the “high quality” term.

This leaves us with the youngest of our wikis: the Community wiki. The purpose of the Community wiki is to give the KDE community a place where to coordinate. Think of leaving notes for thoughts. Or a list of contributors attending a conference. The current todo-list of a KDE project. In other words: The community wiki is a scratch pad for all sorts of content that does not really fit into TechBase or UserBase. If you are unsure, the community wiki is most likely the right place.

Currently, there is a lot of content on TechBase that never was supposed to be put there. This is because the Community wiki did not exist earlier. So what should be moved from TechBase to the Community wiki? All the articles in the Projects page without exception belong in the Community wiki. Just read through the list and you’ll get the impression that it’s more a dumping ground for some project related content. This is exactly what we NOT want on TechBase. However, people keep putting content there. So this is an appeal to the KDE community: Please use the community wiki! You are free to do there whatever you want :) We have to take care to keep TechBase maintainable (this is also why techbase uses the subpages to structure the content). Sometimes less is more, so please take the time to remove Projects pages no longer needed, or move them to the community wiki. And especially put new content to the Community wiki instead of TechBase. Thanks!!!

Join Kate Development!

The Wheel of Time turns… meaning that the Kate Project has quite along history by now. The Kate Project was started back in December 2000, so it’s almost 10 years old. Development sometimes continues with a fast pace; and at other times there is almost no progress for weeks. But all in all, looking back at those 10 years, we can proudly tell you that the project is very much alive. Let’s take a look at the traffic of our mailing list:

The traffic itself does not say much about the development. It probably tells us that there are quite a lot of people using Kate and reporting wishes and bugs. This is a good thing :) The commit statistics for Kate, KWrite and the KTextEditor interfaces look like this:

Before 2000, Kate did not exist yet. Instead, so these commits come from the KWrite days. The commit rate is quite constant according to this statistic. In fact, there usually are always several developers working on Kate. Some only for a short period to implement single features or fix some bugs, and some long-term contributors. A very nice trend is given by the fact that the core team of Kate grew from about 4 to 7 developers over the last two years. So the Kate Project is very healthy – nice! And of course we are happy for every single contribution. So if you want to get involved in Kate development, join us!

MovingRanges moving on ;)

As with any new code, during adoption bottlenecks show up.

For example the rendering of text lines with many ranges inside was quiet slow. This is now partly addressed by Milian Wolff, thanks a lot.

An other bottleneck was the assumption, that it is fast enough to hash the ranges just by their block and iterate over all of them to search the ranges matching a specific line. This does scale well enough for KatePart itself, but KDevelop creates multi-thousand ranges for small documents. To improve this, an internal special mapping was implemented by David Nolden for ranges which don’t span more than one line. For them an efficient line => range mapping is easy and not to costly.

If both changes are tested a bit more, they can be backported in time for KDE 4.5, which will allow a good usability of KatePart for KDevelop once again after the rewrite, given other bugs are fixed.
