"Compiz is the compositing window manager that works on top of Xgl or AIGLX to enable Desktop Effects. Recently, a community developer named Quinn Storm announced that she would start a Compiz-based fork project called 'Beryl', citing frustration with Novell regarding getting her code fixes accepted into the Compiz upstream source tree. We called Compiz/Xgl maintainer David Reveman to get his side of the story."

"For a long time, Linux has been blamed to boot slowly, compared to other modern operating systems. In this article, we are going to focus on a new init system we developed for our Pardus Linux distribution, Mudur, together with other initiatives that are worth mentioning. Mudur is written from scratch in Python with simplicity, speed and maintainability in mind. It isn't a replacement for the /sbin/init command like some other alternatives, nor just a parallel script executor. Mudur greatly simplified our boot process, making it faster and more flexible. Authors look forward for future boot process research for further improvement and optimizations."

Ignorance can be bliss, but it's not a tight defense, lawyers say. When Apple disclosed Wednesday its internal investigation had uncovered some stock-option backdating, the company said Jobs was aware of the practice but unaware of its accounting implications. The probe also did not find any misconduct by Jobs or other current officers, the company said. In a blend of semantics and general legal analysis, however, securities experts say Jobs could still face some kind of penalty over the situation.

Canonical is the 65-employee start-up behind a popular version of Linux called Ubuntu. The company is betting that it can win a place in the market using a strategy that dominant Linux seller Red Hat has dropped. Red Hat offers two versions of Linux: Fedora Core and Red Hat Enterprise Linux. Fedora Core is free, but relatively untested and unsupported by Red Hat, while RHEL is supported and certified, but must be purchased. With Canonical's Ubuntu, however, the free and supported versions are identical - the approach Red Hat abandoned in 2003.

Microsoft, of all companies, continues to lead the way with free and loose licensing terms around server virtualization software and multi-core processors. As of Oct 1, Windows Server Datacenter Edition operating system customers will have the right to run "an unlimted number of virtualized Windows Server instances". This policy applies to licenses covering new servers and previous licenses upgraded with new version rights. All told, it means that you pay to run Windows Server Datacenter Edition on a server with a set number of processors and can then divvy that box up with any combination of Windows Server Standard Edition, Enterprise Edition and/or Datacenter Edition without needing to count the number of virtual machines being created or pay for extra Windows Server licenses.

"Is Ubuntu an operating system? Last week at EuroOSCON, Mark Shuttleworth gave the closing keynote outlining what he believes are the major struggles faced by the open-source/free-software community. During his talk, it became clear that Ubuntu is trying to achieve a radical shift in the software world. Ubuntu isn't trying to be a platform for mass-market application software: it is trying to be the primary provider of both the operating system and all the application software that a typical user would want to run on his machine. Most Linux distributions are like this, and I think it is a dangerous trend that will stifle innovation and usability."

Red Hat has an NDA cooperation with Marvell for the wireless chips that they want to use for the One Laptop per Child-project. The idea of this is that both parties think Marvell will be more open in the future, but this is absolutely not the path they should walk, according to OpenBSD's Theo de Raadt. "I am getting really tired of 'open source' people who work against the open source community. Our little group can probably take credit for having 'opened up' more wireless devices than the rest of the community, and therefore we feel we have a better grasp of the damage OLPC has done here."
