5 reasons wikis rock for documentation

Monday 1st of June 2015 09:18:47 PM
You may not have noticed, but people often become attached to their favorite technology. This could be a mobile phone, a programming language, or a text editor. When you work on someone else's project, you generally have to go with whatever the prevailing tools and languages are, but when it's your own project, you get to choose the toys. Documentation requires technology, too, but most people have less of a pre-set opinion about documentation tooling than they do about web frameworks and version control systems. So how is a project to choose?read more

  • Libinput 0.16 Now Supports Devices Like The Chromebook Pixel
    The plans for Libinput 1.0 haven't yielded fruit yet, but libinput 0.16 is out this afternoon as the latest version of this input library used both by Wayland and X11 (and potentially Mir moving forward).
  • libinput and the lack of device types
    libinput uses udev tags to determine what a device is. This is a significant difference to the X.Org stack which determines how to deal with a device based on an elaborate set of rules, rules grown over time, matured, but with a slight layer of mould on top by now. In evdev's case that is understandable, it stems from a design where you could just point it at a device in your xorg.conf and it'd automagically work, well before we had even input hotplugging in X. What it leads to now though is that the server uses slightly different rules to decide what a device is (to implement MatchIsTouchscreen for example) than evdev does. So you may have, in theory, a device that responds to MatchIsTouchscreen only to set itself up as keyboard.

    All of the Intel x86 systems were running Ubuntu 15.04 with the Linux 4.1 kernel and the rest of the same software make-up. With the Utilite, Ubuntu 12.04 with the Linux 3.0 kernel was used due to newer releases not being supported by CompuLab. With the Jetson TK1 was Ubuntu 14.04 with the Linux 3.10 kernel, likewise due to NVIDIA not providing any newer official images. Due to running OpenGL (non-GLES) tests, only for the x86 systems are the graphics test results while for all of the processor-bound tests are results for all six systems in total.

And for the case you shouldn’t have seen it there was a series of interviews with Krita users (and thus users of KDE software) you should have read at least in part.

Even when configured for one task, such as file management, Konqueror can be used for other tasks such as web browsing.
  • KDEPIM KF5
    I started porting of kdepim to KF5 1 year ago (in may 2014). When I started it I thought that it should be easy.

Secondary kdepim is not just KMail, it contains the kdepim libs + akonadi + kdepim runtime + kdepim apps (as korganizer, kmail, etc.).

  • A good start with room to improve: Thoughts on Citrix's Linux VDA, plus a video demo from Citrix Synergy 2015
    One of the more surprising things in a relatively unsurprising Citrix Synergy was the round of applause created by the announcement of the Linux VDA Tech Preview. I think it’s great, but it’s not the kind of announcement you’d think would garner much more than a murmur, let alone get a larger reaction from the audience than the iBand’s rendition of “Hey Ya!"
