Yesterday I presented Bonnie++ and IOzone benchmarks for a solid state drive in a client machine and discussed the relative merits of purchasing an SSD over a set of hard disks costing the same money. Today I'll look at deploying and taking advantage of the extremely fast seek time of the SSD on a server.

Law and order is one of the cornerstones of a civilized society. Establishing rules of conduct, spelling out acceptable and objectionable behavior, defining the consequences for anyone who violates those laws and deciding who will enforce them are all essential to maintaining peace and harmony.

Launched yesterday, and available now in Debian "experimental," KDE 4.1 is what 4.0 should have been, one reviewer finds. With some 70,000 software changes since 4.0 launched at Google HQ last Jan., is KDE 4.1 about to usher in the future of the Linux desktop? The first RC1 release of KDE 4.0 appeared nearly a year ago. The full major 4.0 version was then officially launched at Google headquarters on Jan. 18. Then, team KDE really got busy, implementing a roadmap that called for minor releases each month. Those releases, in turn, culminated with the release of KDE 4.1 yesterday.

Even the most casual observer of the linux-kernel mailing must have noticed that, in the shadow of the firmware flame war, there is also a heated discussion over the management of security issues. There have also been some attempts to turn this local battle into a multi-list, regional conflict. Finding the right way to deal with security problems is difficult for any project, and the kernel is no exception. Whether this discussion will lead to any changes remains to be seen, but it does at least provide a clear view of where the disagreements are.

Calculating subnets is an essential skill for network administrators, and even home users with small LANs will benefit from understanding how they work. This installment of Networking 101 offers some tips and practice exercises to get you started.

Classmate ain't the XO laptopThis morning, AP bring us news thatPortugal pledged 500,000 Classmate PC's for elementary school students, the largest order for Intel's4P Computing offering to date.Sadly, I think this is an epic error on the part of the Government of Portugal, for three reasons..

It's small and silent, sports an array of ports on the back but only one tiny white LED on the front, and it can help you spend hours of time in front of your TV -- and it runs Linux. It's the Netflix Player from embedded device specialist Roku, and we got our hands on it for a review of the service and the hardware. Netflix began delivering on-demand video in January 2007, restricting viewers to watching content through Internet Explorer on Windows. The "Watch Instantly" option uses DRM-encumbered Windows Media Video to lock out all non-Windows Media Player plug-ins (including licensed media players such as Fluendo's WMV codecs). The in-browser player includes minimal playback controls, and the service is built-in to all existing Netflix accounts. Subscribers on plans that include a fixed number of discs per month are alloted a fixed number of hours through the Watch Instantly service; subscribers on unlimited disc plans can watch an unlimited number of Watch Instantly programs.

In an interview with ZDNet Asia, Oliver Bell, Microsoft Asia-Pacific's regional technology officer, said the company has been focusing on building developer tools for server side applications. He cited two examples of such tools. The first one called OpenXML PowerTools allows the OOXML documents to be created and modified without needing Microsoft Office installed. The other tool, OpenXML SDK, offers a kit to help developers create third-party applications that read and write OOXML documents.

Yahoo, HP and Intel are collaborating on an ambitious research endeavor called"Cloud Computing Test Bed" -- designed to support cloud computing research and education at universities. Users will be able to develop and test software, data center management, and hardware associated with cloud computing on this large-scale grid.

Intel's low-cost laptop initiative is set to get a boost Wednesday from Portugal's government, which is pledging to provide elementary school students with 500,000 computers based on the chipmaker's Classmate PC design. The announcement brings Intel's rivalry with the One Laptop Per Child organization into the spotlight once again.

The KDE development community announced today the official release of version 4.1, the first major update of the new 4.x series. This release finally delivers on the promise of a next-generation desktop environment and resolves most of the problems that afflicted the original 4.0 release. The new version includes a huge number of interface enhancements, application improvements, bug fixes, new software, and new infrastructure components; according to statistics released by the KDE developers, over 20,803 separate changes have been committed to the version control system since the 4.0 release.

PostPath is a drop-in Microsoft Exchange alternative based on the open source Postfix MTA. PostPath director of product management Sina Miri calls PostPath the "only" drop-in Exchange replacement, and he says that ability is the reason why his company makes PostPath available only with a proprietary license, despite its open source roots.

The next version Debian has come a step closer to completion with the freezing of the current testing distribution version codename Lenny. This will form the basis of Debian 5.0, expected in September. The freeze means that package developers who have not uploaded software for inclusion in the Debian 5.0 release have effectively missed the boat. It also means that their packages will almost certainly be omitted from the next versions of popular Linux distros such as Ubuntu, Xandros and Linspire that are based on Debian.

Solid state drives (SSD) have many advantages over traditional spinning-platter hard drives including no noise, low power and heat generation, good resistance to shock, and most importantly, extremely low seek times. To see just how much an SSD might improve performance, I used Bonnie++ to benchmark a contemporary SSD as it might be used in a laptop computer. Without going into details, SSDs may use single-level cell (SLC) or multi-level cell storage, with SLC drives typically offering better performance.

The obvious thought came to me while writing last week's column ("SCO Group: Its future is all used up") that about the only folk (other than the deluded and amoral management of the SCO Group) that want the SCO Group effort attacking Linux and other open source initiatives to succeed is Microsoft. So I decided to explore that side in this follow-up column, but a bit of reading led me to the conclusion that things are not as simple as they appear.

Although not actually available until September in the UK, ASUS has announced the full specification of its new Eee Box. Everyone and their Auntie seems to be spinning cartwheels over the Eee PC, so perhaps it should come as no surprise that there is a little surge of nervous energy running through my fingertips as I write about the UK launch of the new Eee Box.

There's a common theme here: replacing GNU/Linux at the bottom of the open source stack, and making the applications more Windows-friendly. Microsoft seems to think - rightly, in my view - that the free software threat to its business will be blunted considerably if it can move users of enterprise open source applications onto Windows by encouraging and optimising ports to that platform.

At this point in the game, Microsoft should really come clean with a statement that rescinds its Linux/patent/suing threat altogether. Granted, Microsoft put itself in a hard spot with this one, since it had its channel singing the same tune for those murky months after the threat. If it stands up says,"Sorry, just kidding!" that won't make the channel partners happy, particularly if they used the threat to convince customers they must buy SUSE or Windows over Red Hat and other distros. But the fact is, we are seeing actions by Microsoft that indicate that the"suing Linux users" jig is up.

Interoperability is fast becoming a key watchword in business computing circles. Open source products continue to gain enterprise acceptance. With that acceptance comes an increase in users who demand that data produced with one application to work with data produced for another application -- or even another operating system.

Hard drives are slow and fail often, and though abolished for working memory ages ago, fixed-size partitions are still the predominant mode of storage space allocation. As if worrying about speed and data loss weren't enough, you also have to worry about whether your partition size calculations were just right when you were installing a server or whether you'll wind up in the unenviable position of having a partition run out of space, even though another partition is maybe mostly unused. And if you might have to move a partition across physical volume boundaries on a running system, well, woe is you.
