Unity, the next generation desktop?

Filed under

Simply speaking, Unity is another visual representation to allow easy access to your installed programs. Compared to launching an application by using a keyboard shortcut, a menu entry, a docky/cairo/... dock icon or a graphical shortcut on the desktop, Unity uses a launchbar glued to left side of the screen plus a graphical menu where all applications are displayed as icons. Gone are the classic menus. Is this something to be afraid of? No, so technically speaking I see no reason to utter something negative about this way of representing an access method to launch applications.

So, if the change is not 'technical', maybe the 'problem' is to be found in the user/device interaction, about how users perceive input devices and how to make it easier to use those.
Currently we live in an environment where the WIMP principle reigns. It does so nearly three decades and it could be showing its age. Is the mouse as pointing device about to be replaced by fingers touching screen surfaces? This is nothing new. PDAs, mobile phones and iPad users are quite familiar with this way of interacting with their device and it works 'naturally' so to speak.

But older IT technology, typically computers - be it PC's, laptop or netbooks - still rely on a thirty year old concept. A screen, a keyboard and a mouse.

The new display interfaces will more and more include touchscreen capabilities.

OSS Leftovers

  • DataBasin - object inspector and updates
    First, the underlying DataBasinKit framework got an important update.
  • In-demand dev skills, understanding licensing, and more open source news
  • Higher ed systems expanding access to open-source materials
    Open-source learning technology is at the core of higher education for institutions that want to reach broader audiences with very strict ideas about how convenient learning should be. But developing these initiatives does not happen quickly or easily. It requires strong leadership in information technology, expertise to determine which solutions work best for a campus, and a financial commitment to making sure the technology is sustainable.
  • Proxmark Pro Proxmark3 Standalone Open Source RFID Tester (video)
    Rysc Corp has unveiled a new open source board in the form of the Proxmark Pro which now offers a true standalone client and RFID test instrument, check out the video below to learn more. The Proxmark Pro will feature an FPGA with 5 times the logic cells of the Proxmark3 and will remove the need to switch between HF and LF bit streams during operation, to use developers.
  • ErupteD Brings Vulkan To The D Programming Language
    The D programming language is just the latest to have support for Vulkan alongside C++, Rust (via Vulkano, if you missed that project), Go, and many other modern languages getting bindings for this Khronos Group high performance graphics API. Should you not be familiar with the D language, see Wikipedia.
