The Aloof Blackjack Player Who Created Our Digital World

Jovan Stosic February 21, 2017

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.

Configure Delay for “Disable Touchpad while Typing” Xubuntu | Computer Correct

Jovan Stosic February 21, 2017

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)

Cron

The software utility Cron is a time-based job scheduler in Unix-like computer operating systems. People who set up and maintain software environments use cron to schedule jobs (commands or shell scripts) to run periodically at fixed times, dates, or intervals. It typically automates system maintenance or administration—though its general-purpose nature makes it useful for things like downloading files from the Internet and downloading email at regular intervals.[1] The origin of the name cron is from the Gr

Unix

Jovan Stosic February 21, 2017

Unix (/ˈjuː.nɪks/; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, developed starting in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.[3] Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties from the late 1970s, leading to a variety of both academic and commercial variants of Unix from vendors such as the University of California, Berkeley (BSD), Mic
