1.- x2vnc allows the console (keyboard and mouse) on an X terminal to be used to control another console running a VNC server.

x2vnc allows the console (keyboard and mouse) on an X terminal to be used to control another console running a VNC server. It also provides ancillary functions like clipboard sharing.
The software was developed in 1998 by Fredrik Hubinette, based on source code from x2x and VNC.
What it does.
This program will let you use two screens on two different computers as if they were connected to the same computer. Even if one of the computers runs Windows 95/98/NT and the other one runs X-windows. If they are both running Windows, you probably want to use Win2VNC instead.
Personally, I have two computers, both with linux installed, but I often have to run Windows 95 or Windows NT when working, and I just got tired of switching between the two keyboards. Therefore I wrote this program. While running this program I can move the mouse pointer beyond the right edge of my X display, and then the pointer will appear on the screen on the other computer. If you have ever used x2x or a computer with two graphics cards, you know what I am talking about.

2.- Tango Icon Theme Guidelines.

The Tango icon theme's goal is to make applications not seem alien on any desktop. A user running a multiplatform application should not have the impression that the look is unpolished and inconsistent with what he or she is used to. While this isn't about merging styles of all desktop systems, we do aim to not be drastically different on each platform.
Along with a generic type fallback, having a similar style will help in the transition phase with some legacy icons which may still remain on a user's particular desktop.
Color Palette.
Having a common color palette is required to have a consistent look across all icons. Visual style is heavily influenced by the colors used.
The Tango color palette consists of 27 RGB colors, as shown on the image below. Most desktops allow for 24-bit RGB icons (+8-bit Alpha channel).

8.- x2x allows the keyboard and mouse on one ("from") X display to control another ("to") X display.

x2x allows the console (keyboard and mouse) on one X terminal to be used to control another X terminal. It also provides ancillary functions like clipboard sharing.

The software was developed in 1996 by David Chaiken at DEC. It is currently maintained by Mikhail Gusarov.

x2x joins a pair of X displays together, as if they were a single multiheaded display. The pointer can be warped between displays, or, depending on how you start x2x, can slide from one display to the other when it runs off the edge of the screen. Keyboard focus also moves between displays in the way you'd expect, and the X selection propagates around. At least one of the displays involved (specifically, the one being controlled remotely) must support the XTEST extension. (The servers shipped by Debian support this.)

10.- Tizen OS: Can Samsung and Intel’s mobile OS compete with Android?

TizenOsIn the wake of Meego’s demise a new open source mobile operating system has emerged. Known as Tizen and backed by Samsung and Intel, the Linux-based OS recently hit the version 1.0 milestone and has even been paired with an official reference hardware platform. Unlike the alternative OSes that came before it, Tizen does not use the Qt application framework. Instead, Tizen apps are created using HTML5 and other web standards. It is intended to be used in smartphones, tablets, smart TVs, vehicle entertainment systems, and low-power notebooks. Tizen is currently being developed by a partnership between Intel, Samsung, the Linux Foundation, and others. The latest partner is Sprint-Nextel, which has announced its intent to join the Tizen Association and to feature Tizen-powered smartphones in its future product lineups.
