Sabayon Linux

Sabayon Linux or Sabayon (formerly RR4 Linux and RR64 Linux), is a Gentoo-based European Linux distribution created by Fabio Erculiani and the Sabayon development team. Sabayon follows the "out of the box" philosophy, aiming to give the user a wide number of applications ready to use and a self-configured operating system.

Sabayon Linux features a rolling release cycle, its own software repository and a package management system called Entropy. Sabayon is available in both x86 and AMD64 distributions and there is support for ARMv7 in development for the BeagleBone.

It is named after an Italian dessert, zabaione which is made from eggs. Sabayon's logo is an impression of a chicken foot.

Editions

Since version 4.1, Sabayon has been released in two different flavors featuring either the GNOME or KDE desktop environments, with the ultralight Fluxbox environment included as well. (In the previous versions all three environments were included in a DVD ISO image).

Since Sabayon's initial release, additional versions of Sabayon have added four other X environments, including Xfce and LXDE. A CoreCD edition which featured a minimal install of Sabayon was released to allow the creation of spins of the Sabayon operating system; however, this was later discontinued and replaced by CoreCDX (fluxbox window manager) and Spinbase (no X environment) first and by "Sabayon Minimal" later. A ServerBase edition was released which features a server-optimized kernel and a small footprint, but this was later discontinued and integrated into the "Sabayon Minimal".

Sniper rifle

In military and law enforcement terminology, a special application sniper rifle is a crew service, man-portable, high precision, shoulder-fired rifle used to ensure more accurate placement of bullets at longer ranges than other small arms. It is a common misconception that any scoped rifle is a sniper rifle, and while certain long guns are more suited for the application than others, it is the act of using a firearm weapon strategically as a sniper qualified-specialist that designates it as such.

A typical sniper rifle is built for optimal levels of accuracy, fitted with a telescopic sight and chambered for a military centerfire cartridge. The term is often used in the media to describe any type of accurized firearm fitted with a telescopic sight that is employed against human targets, although "sniping rifle" or "sniper's rifle" is the technically correct grammatical term for such a rifle.

The military role of a sniper (a term derived from the snipe, a bird which was difficult to hunt and shoot) dates back to the turn of the 18th century, but the true sniper rifle is a much more recent development. Advances in technology, specifically that of telescopic sights and more accurate manufacturing, allowed armies to equip specially trained soldiers with rifles that enable them to deliver precise shots over greater distances than regular infantry weapons. The sniper rifle itself could be based on a standard rifle: it's hard to define a sniper rifle by the fire modes as some latest designed sniper rifles are semi-automatic fire, for example the M110; however, when fitted with a telescopic sight, it becomes a sniper rifle.
