PF-kernel - kernel patchset for Linux, including patches that are not formally part of the kernel. These patches are:

• branch-ck with Scheduler processes BFS, designed to improve the interactivity of the system;
• IO scheduler BFQ, much uluchayuschy interactive system for disk operations;
• alternate subsystem hibernation TuxOnIce;
• Patch UKSM, created for deduplication memory pages (useful when, for example, several virtual machines of the same type).

After two and a half months of development a new version of the kernel Linux 3.6.

Among other changes, it should be noted are:

• the file system and the storage subsystem:
  • btrfs introduced support for quotas for nested volumes and mechanism for implementing incremental backups atomic;
  • ext4 support in the revised quotas, and increased performance for overwriting files;
  • in xfs made many improvements, including improved performance;
  • improved security dereferencing symbolic and hard links – now you can prevent the kernel to follow the links in the directory with the bit «sticky» (for example, / tmp);
  • added a new interface alerts core user-space tools to change the size of the partition, so that the changes are immediately applied the kernel;
  • improved performance combined RAID-arrays, which is composed of disks SSD;
  • Added support for using swap files via NFS;
  • in virtio-scsi driver adds support for hot-plug / off discs;
  • deleted demon pdflush kernel space due to the processing subsystem VFS;

Yesterday was the release of a cross-platform framework is presented for the development of 3D-applications PixelLight.

PixelLight can be used to develop any type of application, working with three-dimensional graphics, such as games, interactive simulations or visualizations. Includes flexible scene graph allows to compose and visualize almost any three-dimensional scene.

Written in C + +. Its main advantages are flexibility and extensibility. This is not only 3D-engine, but also a complete framework that allows you to combine all the developers need not worry about the presence and version of external libraries (“all I carry with me»), API, or the operating system. The underlying features of the systems and libraries are hidden behind a powerful system components, which greatly simplifies the creation of applications for various platforms. This set of components can be used for applications such aspects as rendering, sound, physics, networking, scripting, and so on.

After two months of development left the next version of the kernel Linux – 3.5.

Of the innovations include:

• in the network subsystem:
  • added to the packet scheduler CoDel , implements the mechanism of active queue management with controlled delay, which is designed to provide quality service to the global Internet, which eliminates the buffer overflow;
  • in the TCP stack added feature of early pereperedachi , which speeds up the recovery of connection when packet loss;
