Show Widget on Desktop with PlexyDesk

PlexyDesk is an extension for your desktop which lets you use your desktop background efficiently. It's powered by Nokia Qt Framework. If you have some scripting skill, you can customize your dekstop with QML and PlexyDesk C++ API, make theme packs (skins) using QML and share it with your friends.

PlexyDesk features:
  • Change your desktop wallpaper by dragging and dropping any image you like from your file manager
  • Fully supports Qt QML
  • Provides support for Qt/3D
  • PlexyDesk widgets can be programmed with shader programs (GLSL).
  • API for writing data models, and C++ widget plugins
  • Dbus api for changing the wallpaper on Linux
  • Various Utility widgets (like a Clock, File browser, and Photo Frame).
PlexyDesk is in early stages so it has many disadvantages such as: we can't change the size of the widgets and there is no support for removing widgets. If you want report bugs, issues, ideas, and suggestions please visit here.

Finnix 106

Ryan Finnie has announced the release of Finnix 106, a small, self-contained, bootable Linux CD distribution for system administrators, based on Debian's testing branch: "Today I am pleased to announce the release of Finnix 106, which contains an important kernel update as well as minor fixes and improvements. Finnix 106 includes Linux kernel 3.5, and notably fixes a major bug observed in Finnix 105 where booting would freeze if the system's disk included an extended partition. With Finnix 105, Project NEALE was announced - an effort to build Finnix releases in a completely automated and normalized way. Finnix 105 was the first release to be produced with NEALE, but the build infrastructure was not available to the public at the time. For Finnix 106, the build infrastructure has been finished and released to the public. See the release announcement and release notes for more details.
