Xara LX forked to replace rendering engine

Filed under

The Xara LX vector graphics editor took a big step forward last week. After months of gridlock between open source contributors to the project and its corporate owners, one of the contributors published his own fork of the code base -- and the company approved, offering to host it in the official Subversion repository.

The stalemate stemmed from Xara's decision to exclude a single library from its GPL source code release. That library, CDraw, is the rendering engine responsible for rasterizing the workspace contents and drawing it to the screen during an editing session. Xara is very proud of the speed and quality of CDraw, to the point where it cites CDraw's speed as the chief advantage of the product over its competition. But the company feared that releasing the source code to CDraw would constitute giving up its competitive advantage. Thus when it launched the open source Xara LX project, Xara bundled it with a binary-only CDraw -- but one explicitly licensed as freely redistributable.

Outside contributors expressed reluctance to invest time in the Xara LX project, citing dependency on the non-free CDraw as the reason. The project languished, each of the two camps seemingly of the opinion that the other was not holding up its end of the deal -- the coders regarding Xara's partial source code release as insufficient and Xara finding the coders' contributions insignificant.

Full Story.

AMD's Catalyst Linux Driver Preparing For A World Without An X Server?

AMD's proprietary Catalyst Linux driver installer is interestingly being prepared for an environment without an X.Org Server. While there's no announcement out of AMD indicating any future support directions for their Catalyst Linux driver, it seems their Catalyst driver will soon be equipped with an option for building the driver packages without X.Org Server support, a.k.a. no building of the fglrx DDX driver.

What is a good EPUB reader on Linux

If the habit on reading books on electronic tablets is still on its way, reading books on a computer is even rarer. It is hard enough to focus on the classics of the 16th century literature, so who needs the Facebook chat pop up sound in the background in addition? But if for some reasons you wish to open an electronic book in your computer, chances are that you will need specific software. Indeed, most editors agreed with using the EPUB format for electronic books (for "Electronic PUBlication"). Hopefully, Linux is not deprived of good programs capable of dealing with such format. In short, here is a non-exhaustive list of good EPUB readers on Linux. Read more

Qt Licence Update

Today Qt announced some changes to their licence. The KDE Free Qt team have been working behind the scenes to make these happen and we should be very thankful for the work they put in. Qt code was LGPLv2.1 or GPLv3 (this also allows GPLv2). Existing modules will add LGPLv3 to that. This means I can get rid of the part of the KDE Licensing Policy which says "Note: code may not be copied from Qt into KDE Platform as Qt is LGPLv2.1 only which would prevent it being used under LGPL 3".
