I have just finished watching a documentary named: “What are dreams?” It is exhilarating to watch how wonderful our brains are. Dreams are another magnificent working aspect of brain. I felt really interested when I went through certain aspects of dreams. For example, during REM (Rapid Eye Movement) sleep brain actually sends signal to completely paralyze muscles. Do you know why? Because that is a wonderful period of time. Brain stem (the core part of brain) actually sends signal to make the brain super active. If the muscles are not paralyze, they’ll be activated and the person will walk or run or …

OpenCV bitpieces
Suppose DoIt is a function that takes a cv::Mat as argument and suppose AMat is a cv::Mat. In openCV 2.1.0 [code lang=”cpp”] //You cannot do this DoIt(AMat*50.0); //Or this DoIt((cv::Mat)AMat*50.0); //You have to do either this: cv:Mat temp = AMat*50; DoIt(temp); //Or this DoIt((cv::Mat)(AMat*50.0)); //Or this DoIt(cv::Mat(AMat*50.0)); [/code]
An Elevator Pitch
I’ve seen a nice video today defining elevator pitch. The summary and key points of the video is as follows. What is an elevator pitch? An elevator pitch is a short discussion or lecture that occurred in a very short amount of time like the discussions happened during climbing by an elevator.

Chronology of my life
As far as I can remember: We lived in the Manager’s House in Horipur 100MW Gas Turbine Power Plant, Narayanganj, Bangladesh. My father was the manager of that power plant at that time. It is beside the river শীতলক্ষা (Shitalak-khaa). This is a one-storied building. There was a big jute plant just in the opposite side of the wall. Once there was a huge fire in the jute storage. The fire reached the sky. It took three days and and a huge amount of water from the Shitalakkha river. 1989: There was a great flood this year.
Invariant Subspaces
[If the equations are not visible please try refreshing the page] A linear transformation f is a transformation maintaining the following two properties: Any linear transformation can be represented using a matrix multiplication with a vector. Any linear transformation splits the n-dimensional space V into k f-invariant subspaces – direct sum of which returns the original space, V. These subspaces show eigenvector-like property i.e. when any vector from such a subspace is transformed using then where is a scaler value. Now, when all these f-invariant subspaces are one-dimensional, then the basis vector of each such one-dimensional vector is called an …
Building Vocabulary: Appropriate Tools and Strategies for KUETians
We, KUETIANS, always feel an obvious lagging in our vocabulary. One of the main reasons for this is our apathy towards English books, magazines and novels etc. During my 4 years in KUET, I never saw anybody to read an English novel (including me). Nobody even advised to do so. This bad habit eventually lead to a lack in confidence in the English skill measuring tests (like TOEFL and IELTS) as well as the aptitude tests (like GRE). Our teachers also show severe antipathy for learning English. Although the medium of instruction is English, they deliver lectures in Bengali. Moreover, …
