"Many directories in the UNIX file system serve a special purpose, and certain directories are named per long-standing convention. In this instalment of the 'Speaking UNIX' series, discover where UNIX stores important files."

On June 22nd Mesa 7.0 was released, featuring OpenGL 2.0 and 2.1 support among other features.

The Linux community is splitting - right down the middle, at this point - over Microsoft's controversial claims that the open-source operating system infringes on patents it holds. Last Tuesday, Mandriva became the third Linux vendor within five days to say it isn't interested in signing a licensing deal with Microsoft to avoid possible infringement claims. A blog posting to that effect by Mandriva CEO Francois Bancilhon followed similar declarations by officials at Red Hat and Canonical.

Another turn in the Apple-ZFS saga. Apple has made available a developer preview of ZFS for Mac OS X with read/write capability. The preview is available to all ADC members. From the readme file: "ZFS is a new filesystem from Sun Microsystems which has been ported by Apple to Mac OS X. The initial (10.5.0) release of Leopard will restrict ZFS to read-only, so no ZFS pools or filesystems can be modified or created. This Developer Preview will enable full read/write capability, which includes the creation/destruction of ZFS pools and filesystems." Update: Will it ever end? The release has been pulled from ADC by Apple.

"The Series 5 pocket computer from Psion was launched 10 years ago this week. It was a remarkable achievement: entirely new silicon, a new operating system, middleware stack and applications were developed from scratch in just over two years. This was the last time anyone undertook such a daunting task: it may be the last time anyone ever tries, either."

Today Patrick J. Volkerding announced Slackware Linux 12.0 RC2. There are no big new features, this is almost a collection of bug fixes. A review of the RC1 can be found here (translation). A review of the Slackware-based Vector Linux 5.8 SOHO can also be found here.

As was to be expected, the Longhorn Reloaded team has been shut down by Microsoft. "It is with sad news that I have to inform you that today due to a cesit and decist letter we recived from Microsoft we are no longer able to provide you with a download link to Longhorn Reloaded. It deeply saddens me that although Microsoft hknew about this project for many months they only issued us with this notice a few days after we started to distribute the iso via torrents and ftp server."

"I was somewhat surprised (but pleased) at the level of interest back when I published my Windows Vista - 90 Day Vulnerability Report. It was about the earliest span of time I thought might give us some indicators, and the indicators did look good. Six months is a much more interesting time frame, and gives us the opportunity to see if the early trend indicators are holding up, or if the early signs of progress were a short-term gain."

"The Free Software community is well known for its diversity. This is most obvious at the application level, but even exists in the context of operating systems. David Chisnall takes a break from UNIX-derivatives and explores some of the more esoteric options." Note: From experience, I can say that the author's claim that "Haiku is more or less ready for their 1.0 release in terms of features" is a bit overambitious.

Guido van Rossum, the creator of the Python programming language, has published on his blog an interesting status report for Python 3.0 ('Python 3000'), the upcoming major revision to the language scheduled for mid-2008. He discusses the rationale for redesigning the language, syntax changes, new features and libraries and inter-compatibility issues.

"One of the salient points repeated at the WWDC keynote was Leopard's support for '64 bits top to bottom'. However, a close peek at the slide shown this year showed a subtle difference to last year's - the word 'Carbon' was missing. Of course a storm of confusion soon ensued, with the usual wailing and gnashing of teeth from some quarters and polite shrugging from others. Apple stock fell and rose again, some developers professed bliss while others threatened to leave the platform, non-developers wrote learned analyses about obscure technical points, not to speak of reports of raining frogs or even an unconfirmed Elvis sighting in a Moscone restroom. Allow me to try to explain all (well, Elvis excepted)."

"Now that Fedora 7 has been released, Fedora project leader Max Spevack has a little bit of breathing room. Like nature, LWN abhors a vacuum, so we sent Max a list of questions and a request for answers. We are now happy to present the answers."

"At Phoronix we are constantly exploring the different display drivers under Linux, and while we have reviewed Sun's Check Tool and test motherboards with Solaris in addition to covering a few other areas, we have yet to perform a graphics driver comparison between Linux and Solaris. That is until today. With interest in Solaris on the rise thanks to Project Indiana, we have decided to finally offer our first quantitative graphics comparison between Linux and Solaris with the NVIDIA proprietary drivers."

There have been some interesting developments in the Haiku/BeOS world the past few weeks. Firstly, SkyOS developer Peter "Darkness" Speybrouck has been working on accessing SkyFS/BeFS partitions from Windows. Secondly, Opera 3.62 runs on Haiku. Lastly, if you have an Intel Mac, you can use VMware Fusion to run Haiku in Mac OS X; Haiku does not support EFI, so this is your only chance of running Haiku if you own an Intel Mac.
