Ubuntu 13.10 has just released. Yet, as lately happen to Ubuntu, bugs keep on appearing. There is a very noticeable and annoying bug that happened to Ubuntu 13.10, at least on my Asus Laptop. The mouse pointer will flicker indefinitely and will sometimes missing. It's very troublesome especially when we try to browse a website and go to the specific links or buttons. Thankfully, there is a workaround for this. The good thing, it is very simple and does not need any advanced Linux expertise. Below are the steps: Open the System Preferences . Open the Display setting that is located at the Hardware section. Choose the unknown monitor and DISABLE it. Click on the Apply button and choose to keep the configuration when asked. That's all. Hopefully it's helpful and feel free to add if there are other methods to solve this annoying problem. Enjoy....

Just read this, again, from the Internet. Nice story to share. When things in your life seem almost too much to handle, When 24 hours in a day is not enough, Remember the mayonnaise jar and 2 cups of coffee. A professor stood before his philosophy class And had some items in front of him. When the class began, wordlessly, He picked up a very large and empty mayonnaise jar and proceeded to fill it with golf balls. He then asked the students, if the jar was full. They agreed that it was. The professor then picked up a box of pebbles and poured them into the jar. He shook the jar lightly. The pebbles rolled into the open Areas between the golf balls. He then asked the students again if the jar was full. They agreed it was. The professor next picked up a box of sand and poured it into the jar. Of course, the sand filled up everything else. He asked once more if the jar was full. The students responded with a unanimous 'yes.' The professor then produced two cups of coffee from un

Greatest Common Divisor (GCD for short) is the largest positive integer that divides two numbers. In other words, the greatest common divisor of a and b is, as its name suggests, the largest positive integer d such that d | a and d | b . In this post, we will see how we can calculate GCD efficiently using an algorithm that is known as Eucledian Algorithm . The key thing in this algorithm is division with remainder , which is simply the method of "long division" that you learned in elementary school. Thus if a and b are positive integers and if you attempt to divide a by b , you will get a quotient q and a reminder r . Below is the theorem used for this algorithm: Let a and b be positive integers with a >= b. The following algorithm computes gcd(a,b) in a finite number of steps. (1) Let r 0 = a and r 1 = b (2) Set i = 1 (3) Divide r i-1 by r i to get a quotient q i and remainder r i+1 , r i-1 = r i .q i + r i+1 with 0 <= r i+1 <= r i (4)
