The transformation of one of my 8-years-old kid-students

If properly trained, in an year time even a 7-years-old kid can transform himself vis-a-vis software knowledge. Have a look at the following videos.

- How to find the smallest number in an array - October 2018

-  Singleton Pattern - February 2019

- How to develop a Scramble - Unscramble app in Android - May 2019

-  App store - current

Google Play store profile of Ridit - an 8 years old boy...

Towards the end of 2018, this kid-student was practising some simple Java programs. After 4 months, he transformed himself and discussed about Singleton Design Pattern and after 7 months he started discussing about Android apps. And in October 2019, this kid has his own Google Play Portfolio ( the last link). i know its a long journey to become an ace developer, but proper training is very important for the Indian software engineers. I think people will agree with me about this point.

English is just a language - speaking English is not a skill...

English is just a language to communicate. This cannot be used as a substitute for skill.

This video which explains the Observer Design pattern in Bengali is dedicated to all those Bengali students who despite their Bengali medium schooling background have become bright engineers of India...

Providing engineering education in the mother tongue offers a multitude of benefits for students, leading to improved comprehension, stronger analytical skills, enhanced learning environments, wider access, linguistic diversity promotion, and global competitiveness. By valuing and utilizing the mother tongue, we can empower students to excel in engineering while preserving cultural heritage and fostering inclusive learning opportunities.

Engineering college study revisited - the simulation of PID Controller

Its really fascinating to revisit the stuffs that i studied so thoroughly during engineering. PID control is one such thing. Only difference is that, during my student life i did not know anything about software and now i know software pretty well... I have already spent approximately 15 days time in Robotics. Time to implement this kind of PID controller in the movement of a robot in ROS. Watch how the stability, robustness, time to reach the target, noise picking and all such things which are important in the control system are changing with the PID controller with varying values of Proportional gain (P), Integral Gain (I) and derivative gain (D).

Android Internals - UI Events...

i know the way we started learning computer science almost three decades ago is absolutely different from the way students learn computer science these days. 

students these days probably start programming keeping AI, Robotics and similar stuffs in mind. 

However, it is also the fact that the basics have remained the same.

For example, the way event-handling works in different UI based OS is almost the same.

I remember when i studied Windows/ Visual C++ in 90's, i was really awed (rather scared)  by the MFC's dreaded 

DECLARE_MESSAGE_MAP

BEGIN_MESSAGE_MAP 

and 

END_MESSAGE_MAP 

macros... 

That's why i have made this video to throw lights on the way UI event handling is done in Android.

Here goes my investigation on the Android internals vis-a-vis an UI input event. 

i always wanted to get involved in my software job as an inquisitive engineer and not just as a programmer. 

Hence when Google made Android's framework code open-source, it became a boon for me. 

It opened the door for doing in-depth investigation... 

Hope you like the video...

Happy learning

Enjoy...
