Apple, which last week asked that developers provide feedback on their experiences using pre-released builds of Mac OS Leopard, has followed up by seeding a significant stability update to the next-generation system software. The latest seed, labeled Mac OS X Leopard 9A500n, arrived via Leopard's Software Update mechanism as a 'recommended' update for all developers running Mac OS X Leopard build 9A499.

Jeff Jones has published another one of his vulnerability scorecards comparing various operating system offerings. As always, these figures just list the patched vulnerabilities over the designated period of time; they do not take into account any unfixed or undisclosed vulnerabilities. Hence, these reports are not proper measurements of security - they are just that, a tally of fixed vulnerabilities. Any conclusions like "x is more secure than y" cannot be drawn from this data set. As always, do with it as you please.

"With Bill Gates' announcement earlier this year that Windows Home Server would be available as a 'system builder' product (that means 'OEM' to most hardware geeks), enthusiasts and system builders alike have been looking forward to its release. With several different rumors being floated last week regarding when Windows Home Server would hit store shelves, we checked in with Microsoft to get the full and somewhat-confusing story. The short version is: it's already out in the wild, but catching a copy from your favorite reseller may prove tricky for at least two more weeks."

"Freespire, the free as in beer version of the Linspire Linux distribution, this month released Freespire 2.0, the first version of the operating system based on the popular Ubuntu distribution, and the first to contain proprietary codecs and drivers. Despite its attractive appearance, it left me with mixed feelings."

"A new startup out of MIT emerged from stealth mode today to announce that they're shipping a 64-core processor for the embedded market. The company, called Tilera, was founded by Dr. Anat Agarwal, the MIT professor behind the famous and venerable Raw project on which Tilera's first product, the TILE64 processor, is based. Tilera's director of marketing, Bob Dowd, told Ars that TILE64 represents a "sea change in the computing industry", and the company's CEO isn't shy about pitching the chip as the "first significant new chip architectural development in a decade". So let's take an initial look at what was announced about TILE64 today, with further information to follow as it becomes available."

"This paper examines whether OOXML can be fully implemented by vendors other than Microsoft and concludes that a number of application specific and undisclosed behaviours (as well as a number of other technical flaws) in the proposed standard make this impossible. Also while Microsoft has waived patent claims for the explicit and required parts of the specification it is clearly stated that this does not extend to the undisclosed behaviours or ambiguous definitions, providing a legal as well as technical barrier to OOXML's implementation."

"Apple's iWork '08 boasts improvements to the software suite's word processing and presentation applications, but - more importantly - it fills the suite's spreadsheet hole with Numbers. eWEEK Labs ran Numbers through its paces, and found it to be a strong addition to the productivity software market and a promising alternative to Microsoft Excel."

"Can you imagine a computer history museum that has to be packed up and put away each winter and then unpacked each summer, and which has three potbellied pigs as its mascot? I can, because I've just visited the DigiBarn, a wonderful trip down silicon memory lane that's nestled into a 19th-century farmhouse deep in the Santa Cruz mountains, about 90 minutes south of San Francisco."

"The Debian project has updated the stable distribution Debian GNU/Linux 4.0. This update adds security updates to the stable release, together with a few corrections to serious problems. As always, the first point release also corrects a few issues that have been noticed too late in the release process to stop the release, but still should be fixed."

IBM has introduced a release of its z/OS mainframe operating system with new features that increase the system's security for online commerce and business transactions. IBM officials said the new operating system release is in line with what the company has been calling the renaissance of the mainframe. And as mainframes run a vast portion of the world's financial services, retail and other large businesses, security was a major concern for this latest release, IBM officials said, in Armonk, N.Y.

Both GNOME and GARNOME 2.19.20 have been released. "This is our seventh development release on our road towards GNOME 2.20.0, which will be released in September 2007. New features are still arriving, so your mission is simple : Go download it. Go compile it. Go test it. And go hack on it, document it, translate it, fix it."

An interview with IBM's Vice President of Open Source and Standards about their Open Source Strategy, the recent pledge of its patents for more than 150 open software standards, his take on the ODF vs. XML issue, and much more in The LXer Interview of Bob Sutor.

"Gutmann generated a lot of heat last December with the publication of a paper that called Windows Vista's Content Protection scheme 'the longest suicide note in history'. He updated it in April, mostly to call his critics names, and he updated it yet again yesterday with a top-of-the-page slam at my ZDNet colleague George Ou, who took exception with some of Gutmann's claims yesterday. Gutmann has a flair for melodramatic language and headline-grabbing phrases, but his theoretical arguments against Vista's video subsystem fall apart quickly when they make contact with the real world."

"IBM and Sun Microsystems did indeed announce an agreement for deploying the Solaris operating system on IBM servers, but it wasn't the system we guessed: IBM will deploy Solaris for its Intel x86-based System x and BladeCenter servers. It's a significant move, as it validates the presence of Sun's operating system among a broad customer base that few can mistake as a "niche." As Sun CEO Jonathan Schwartz told reporters today, IBM becomes the first Tier 1 reseller of Solaris products and services for x86 platforms." His blog is here.
