How to get permalink of a post on Facebook?

So, you want to point your friends on facebook to a specific post but you can’t find a way to share that post with them via a button or link in the vicinity of that post. Or, suppose you are taking part in a contest on a company’s facebook page or group and you want to deliver maximum likes or comments on a certain post of you there. Then you would certainly want yourself to be able to give your friends the exact URL of that post. Unfortunately, I don’t find any clearly available option to get such a permalink for any post on facebook. Whenever you get a notification about a new comment or like on a post you are subscribed to and you click on that notification then that is the permalink that I always wished I could get without going through the notifications. Luckily, I found the following hidden trick to get it. The permalink of any post on facebook is hidden under its time stamp. So to get the permalink of any post, click on its time stamp reading “x hours ago”, “x seconds ago”, “a few minutes ago” etc. depending on the time passed since that post has been posted as shown in the following screen shot.

Simple Algorithm Design Using Flowcharts and Pseudo Code

Last week, our lecturer of Introduction to Computing gave us an assignment to design algorithms of some simple problems using flowcharts and pseudo code. Many of us found it difficult to do this. Few complained that the lectures given by Mr. Mata-ur-Rehman on this topic were not sufficient enough to make us able to solve these problems. Due to all these things I decided to share some useful resources with my friends which, I think, can help to understand this topic very well. These are two lectures by a professor of Virtual University of Pakistan. These are conducted in a very interesting and efficient way. I am sure, you will not bore watching these lectures and that they will make a great addition to your knowledge of the topic. Also included are the download links of accompanying powerpoint presentations.

Enjoy!
