A red dwarf is a small and relatively cool star on the main sequence, of either K or M spectral type. Red dwarfs range in mass from a low of 0.075 to about 0.50 solar mass and have a surface temperature of less than 4,000 K. Red dwarfs are by far the most common type of star in the Milky Way, at least in the neighborhood of the Sun, but because of their low luminosity, individual red dwarfs cannot be easily observed. From Earth, not one is visible to the naked eye.[1] Proxima Centauri, the nearest star to

Brewster Kahle is a librarian by training and temperament. In the mid-1990s, when many saw the nascent World Wide Web as a place to sell things, he saw it as data that cried out to be preserved and cataloged. Later, he widened his scope to include material — film, books, music — that was not native to the web but could be digitally gathered there.

Every digital device you use operates on a string of ones and zeroes, the binary “yes/no” decision at the foundation of modern computing. It’s a concept so fundamental to our modern day that we rarely stop to wonder where it came from. But it’s all the work of one man: Claude Shannon, whose fascinating story you’ve likely never heard.

So, basically the problem started as this: you got tired of accidently moving the mouse while typing on your laptop, so you naviagated to the touchpad settings screen and enabled the option that reads “Disable touchpad while typing”. You thought that you did well.Then your problem quickly became this: the delay before you are able to move the mouse is much too long. In fact, it is an irritatngly long two full seconds by default. We’re going to adjust that delay and fix both your new problem and old problem with one little command.I’m using Xubuntu 12.04, but this may work for good old Ubuntu as well. It should also work for any other linux distro running XFCE. One caveat: I think that you must be using a touchpad supported by the Synaptics driver for this fix to work (although I’ve never had a touchpad not use this driver on my laptop linux installs)
