Mr Torvalds created two amazing things: Linux and Git. Former is an OS kernel; latter is a version control system. Unluckily, none is prevailing in Malaysia.

When I was a lecturer, creating a new programme with various courses is truly exhaustive. The worst case is recording the changes of the documents for the government agency’s accreditation. If you are systematic, you will backup the files. But backing up the files does not tell you what are the changes you had made. Unless you create another note for each changes you made. But that will be double works. If you say you can use Microsoft Word’s feature to compare the documents and see the changes, it is totally impractical if the two documents are big and there have a vast changes.

Monty Hall paradox

Probability topic is the fundamental concept of the statistics. And machine learning is closely related to statistics. That is why, understand the probability very important if you are doing research, statistics, and machine learning.

Monty Hall is a very interesting problem. It says, if you are given 3 doors to choose. One of them contains a car (which you want), the other two are goats (which you don’t want). After you made your choice, before opening the door, the host will open the door that you didn’t choose yet contains the goat (he knows which door has the goat). Now, if you are given an opportunity to change your choice to another door (which you didn’t choose earlier), are you going to change?
