Busy Kat: Desktop Searches with Kat

The desktop search engine offers new and interesting opportunities for users to access information on their own computers. This new breed of tools lets you search your computer in the same way you would search the Internet.

It comes as no surprise that the first tool of this category was created by Google. Another giant of the computer industry, Apple, has gone beyond this concept, integrating its won desktop search engine, called Spotlight, into the operating environment. In this setting people do not need to know they are using a search tool.

About a year ago, I thought it was about time to equip Linux with an advanced desktop search tool, so I started developing Kat. Of course, I was aware of tools like locate or find that perform searches in the file system. Unfortunately, these tools lack some of the important features of a modern desktop search utility: they are only able to dig for information inside simple text-related files, they don't consider meta data, and their indexes need to be rebuilt manually. Moreover, they only look for information in files. Contemporary computer systems contain lots of information that is outside the file system, such as mail addresses, emails, contacts, play lists, and so on. We set out out create a tool that searches all the possible sources and even considers relationships between bits of information.

SUSE Linux Enterprise High Availability Extension

Historically, data replication has been available only piecemeal through proprietary vendors. In a quest to remediate history, SUSE and partner LINBIT announced a solution that promises to change the economics of data replication. The two companies' collaborative effort is the headliner in the updated SUSE Linux Enterprise High Availability Extension, which now includes LINBIT's integrated geo-clustering technology. Read more

Open source is mission critical for Europe’s air traffic

It is entirely possible to use open source in a highly regulated environment such as air traffic control, says Dr Gerolf Ziegenhain, Head of Linux Competence & Service Centre (LCSC) in Mainz (Germany). Open source service providers can shield an organisation from the wide variety of development processes in the open source community. Read more

  • DRM display resource leasing (kernel side)
    So, you've got a fine head-mounted display and want to explore the delights of virtual reality. Right now, on Linux, that means getting the window system to cooperate because the window system is the DRM master and holds sole access to all display resources. So, you plug in your device, play with RandR to get it displaying bits from the window system and then carefully configure your VR application to use the whole monitor area and hope that the desktop will actually grant you the boon of page flipping so that you will get reasonable performance and maybe not even experience tearing. Results so far have been mixed, and depend on a lot of pieces working in ways that aren't exactly how they were designed to work.
  • GUADEC accommodation
    At this year’s GUADEC in Manchester we have rooms available for you right at the venue in lovely modern student townhouses. As I write this there are still some available to book along with your registration. In a couple of days we have to a final numbers to the University for how many rooms we want, so it would help us out if all the folk who want a room there could register and book one now if you haven’t already done so! We’ll have some available for later booking but we have to pay up front for them now so we can’t reserve too many.

  • Linux Action Show to End Eleven Year Run at LFNW
    Jupiter Broadcasting’s long-running podcast, Linux Action Show, will soon be signing off the air…er, fiber cable, for the last time. The show first streamed on June 10, 2006 and was hosted by “Linux Tycoon” Bryan Lunduke and Jupiter Broadcasting founder Chris Fisher.
