A new patch for the kernel scheduler promises huge improvements in system speed under load. Initial tests show in fact that the new solution represents a drastic improvement.

Those who followed the development of the kernel in the last few weeks or months, could not overlook that the focus of development to the improvement in speed shifted. So the most important change in the next version of the kernel , the removal of the “Big Kernel Lock” (BKL). The BKL was introduced in 1996 with the extension of the kernel for SMP capabilities to control the concurrent access of two processors on the same data structures. This method scales poorly, however, on many processors and threads, and makes the system supports. By removing the locks, the system is effective more quickly, because it eliminated many forced breaks, the areas in front of a concurrent access protected.

A new development of the kernel Thomas Gleixner and Ingo Molnar, promises to illustrate events in the Linux system is better than traditional tools.

The technique called “trace” tool presented offers, according to Thomas Gleixner a way the events in the Linux system and better able to pursue study. Although there is already using tools like ” strace “a way to trace system events, but according to this Gleixner not satisfactory.

The developments that have taken Linux is very vast and important as it is slowly taking place in the market but we have seen that this coincides with Ubuntu Linux and this has caused among new users and those unfamiliar with both the Linux world is of great relevance to the distribution of Canonical.

But in spite of this ah Linux become the basis of various developments and platforms that are making it clear that the versatility of this solution is much greater than that offered by other traditional operating systems.

The evolution in Linux or more specifically within the various Linux distribution is constant. In its early days Linux was reserved for experts computer scientists and geeks in all genres.

Sure things are changed such that now anyone can use and install a Linux distribution without risk. More knowledge is needed to install, operate, administer Linux.

I do not know how long I’m single boot only with Linux (Arch Linux to be more precise). But this weekend, Windows has won a place in a corner of my hard drive.
A little attempt here to explain the why of the thing. In what could be perceived as a step backwards.

Like all things, Linux has its advantages and disadvantages, I will not go back on benefits, explained many times here in the ticket listings on Linux but the disadvantages. For me there are not many well-known in the community: (more…)

After procrastinating for a couples months now I have gone ahead with my plan to move the site. Actually, I moved all my sites from a dedicated server to shared hosting. It wasn’t a quality of service issue that forced the change, xlhost.com is an excellent dedicated provider and I’d use them again.

The main reason for the change is fiscal, 80% to 90% reduction in costs for my on-line presence. The big trade off’s are control, resources, and bandwidth, however there are some benefits. No responsibility for the servers administration is a big one.

Courage and Faith!

While having a dedicated server is great, the cost of running it, not so much. I’ve had this server for 18 months now and done very little with it, other than run a few personal sites. The original plan was find things that might help offset or even pay for the servers upkeep. I never got around to getting that done. I need to find ways to offset the cost, and will be looking at ways to do just that in the near future.

Don’t expect to see banner ads or anything, that isn’t going to happen. However some change is in the air and will arrive soon.
