  With diff-ext, GNOME users can compare and merge files from within Nautilus. If, instead, you use KDE 3, try out kdiff-ext from the same site, which works with Konqueror.

  Chip maker ARM is to get Ubuntu Linux up and running on its ARMv7 processor architcture, part of its plan to get its chips into netbooks and handheld internet devices. It's all about taking the fight to Intel's Atom, of course. The chip giant's processor has become the de facto standard for small, cheap computers.

  Linux and other Unix-like operating systems use the term “swap” to describe both the act of moving memory pages between RAM and disk, and the region of a disk the pages are stored on. It is common to use a whole partition of a hard disk for swapping. However, with the 2.6 Linux kernel, swap files are just as fast as swap partitions. Now, many admins (both Windows and Linux/UNIX) follow an old rule of thumb that your swap partition should be twice the size of your main system RAM. Let us say I’ve 32GB RAM, should I set swap...

     (Wednesday, 19 November 2008 23:39)

  Security is based on three characteristics: prevention, protection and detection. Grsecurity is a patch for the Linux kernel that allows you to increase each of these points. This howto was performed on a Debian Lenny system. Thus some tools are Debian specific. However, tasks can be performed with other distro specific tools or even with universal tools (make).
