Haiku receives donation from Mozilla Foundation

Blog post by kallisti5 on Wed, 2014-06-11 19:09
The Mozilla Foundation has generously donated 15 gently used Intel Mac Minis to Haiku, Inc. to be used as infrastructure, development, and build systems.

These systems are planned to be deployed as updated buildbot slaves, package builders, and used to better support Intel Mac Mini hardware.

Request for comment: A built-in "search to launch" feature for Haiku?

Most operating systems and desktops are moving to the "search to launch" style of starting applications. After using these for a while, I do think they speed up my core desktop usage.

I also think everyone is doing it wrong. Below are my general thoughts on this kind of application launcher:

  • Search to launch shouldn't distract the user.

    Gnome 3, Windows 8, and Unity. All of these user interfaces distract you from your work by bringing up a full-screen launcher. While I think some focus is needed on the "search to launch" interface, it should only distract you enough to let you think about what you want to start.

  • Search to launch shouldn't search files on the disk.

    Haiku has a wonderful gui file search application, lets not try to mesh Applications and Files

  • Search to launch shouldn't replace the traditional desktop experience

    The desktop had a long time to evolve to what it was. Haiku has put a large amount of work into the Tracker resulting in a fast and stable method to manage your desktop.

After some discussion in IRC, many seem open to investigating some of kind of "search to launch" feature for Haiku. The general consensus in IRC was that the best user experience would come from a hot key to bring up the "search to launch" dialog / window. Here you could begin typing the name of a known application from the application menu and press enter to launch it.

Humdinger has actually already made such an application on Haikuware that seems to cover most of these items. The name of the application is QuickLaunch. (here http://haikuware.com/remository/view-details/utilities/desktop-accessori...)

I wanted to post this to get a feeling from the community on how people would react to such an addition.

Radeon HD driver status update

Blog post by kallisti5 on Tue, 2011-10-18 17:11

UPDATE 10/19/2011! Older Radeon HD cards seem fully working minus HDMI. See below.

After several months of hard work (including some redesign of the driver) basic mode setting is working on a small number of Radeon HD cards after r42877. I am using the AMD AtomBIOS parser which executes binary functions on the Radeon HD card to do the real register hitting.

Limitations:

  • No 2D acceleration - 2D acceleration hasn't been started yet. These cards are fast without it however.
  • TV not working - I haven't put a lot of focus on TV just yet
  • Later cards - Radeon HD 5xxx+ cards are still having issues
  • DIG encoders - Later (r700?) Radeon cards can have DIG encoders. These are like digital encoders... but newer and not done yet.

Features:

  • Connector walking - We walk over all possible connectors and probe EDID data on each.
  • Multi-monitor - We can easily support multiple monitors in the driver. We just need to tie in the Screen Preflet code to make it happen. For the moment we set the same VESA EDID video mode on each attached display and get mirroring (as long as your displays are identical).
  • Monitor detection - We can manually trigger monitor detection (in the code, needs a Screen Preflet option) and set the initial mode on each display, hotplug support is planned.
  • Analog video - VGA, DVI-A, DVI-I (VGA)
  • Digital video - DVI-I (digital)

Card support:

  • Radeon HD 2350 - Radeon HD 3450 - Analog / Digital (minus HDMI) working
  • Radeon HD 3470 - Radeon HD 4890 - Unknown. Please test!
  • Radeon HD 5450+ - Analog mode change works, no video. Digital DIG encoder not complete

Things should get smoother at this point as we have a working video for reference.

The radeon_hd driver should be in the nightly images starting with r42888+. If you have a Radeon HD card, feel free to report functionality here or by emailing me.

In closing, for those "pictures or it didn't happen" people... http://twitpic.com/71xhll
