Announcing the third version of his syslets subsystem patches, Ingo Molnar noted that he has implemented many fundamental changes to the code including the introduction of threadlets, "'threadlets' are basically the user-space equivalent of syslets: small functions of execution that the kernel attempts to execute without scheduling. If the threadlet blocks, the kernel creates a real thread from it, and execution continues in that thread. The 'head' context (the context that never blocks) returns to the original function that called the threadlet." As threadlets are only moved into a separate thread context if they block, Ingo refers to them as 'optional threads'. He also describes them as 'on-demand parallelism', "user-space does not have to worry about setting up, sizing and feeding a thread pool - the kernel will execute the workload in a single-threaded manner as long as it makes sense, but once the context blocks, a parallel context is created. So parallelism inside applications is utilized in a natural way."

When Mark Alperin went looking to replace his aging ERP system in 2006, he found himself in the same place as many CIOs of midsize companies -- not feeling terribly sought after by software vendors who prioritize large enterprise accounts, and facing few choices. Alperin serves as COO with CIO responsibilities for Vertex Distribution, a manufacturer and distributor of rivets, screws and other fasteners. He wasn't happy with the two main packages for his industry, from Activant Solutions and Microsoft (neither of which he was using, nor did he want to use.)

This weekend, the Free and Open Source Developers European Meeting will be held at the Université Libre in Brussels, Belgium. FOSDEM, being one of the biggest European Free Software events usually attracts several thousand people each year. The schedule for the KDE devroom is now published. Highlights this year include talks about the semantic desktop, a workshop on educational software and naturally an overview of the status of KDE 4. For the first time we are running a series of cross desktop talks together with Gnome where you can hear how desktop search engine Strigi works. KDE and friends also make appearances in the Lightening Talks track with topics including CMake, OpenWengo and Amarok. If you are planning to visit FOSDEM, add your name to the FOSDEM 2007 Wiki Page.

When a project with the size and scope of KDE gets to be as big as it is, sometimes changing a decision established almost a decade earlier is very difficult. KDE has relied on autotools to build most of the project since its inception, but for the last year, KDE 4 has been building with CMake, a newer build system that is rapidly becoming a heavyweight contender in the world of buildsystems.

Microsoft Corp. on Wednesday released a list of 800 applications it has officially verified so far to run bug-free on Windows Vista. The list is notable for both its brevity and the absence of many applications popular on Windows XP, although Microsoft and analysts said that the majority of XP software can run, albeit with hiccups, on Vista.

Linus Torvalds announced the first release candidate for the upcoming 2.6.21 kernel, ending the two-week merge window, "there's a lot of changes, as is usual for an -rc1 thing, but at least so far it would seem that 2.6.20 has been a good base, and I don't think we have anything *really* scary here." Linus noted that the tickless kernel patch was finally merged into the mainline kernel, "the most interesting core change may be the dyntick/nohz one, where timer ticks will only happen when needed. It's been brewing for a _loong_ time, but it's in the standard kernel now as an option." Thomas Gleixner explained a year ago how this could result in cooler CPUs and power savings, "the tickless kernel feature (CONFIG_NO_HZ) enables 'on-demand' timer interrupts: if there is no timer to be expired for say 1.5 seconds when the system goes idle, then the system will stay totally idle for 1.5 seconds."
