Think of an auto that comfortably seats 3 adults. Now imagine more passengers want to join the ride. The challenge is: how do we accommodate them without disturbing the driver or reducing comfort? Base capacity: The auto comfortably carries 3 adults. Scalability goal: Increase the number of passengers without reducing comfort or safety. Constraints: Driver’s ability to operate smoothly, passenger comfort, and ride quality. In computing: New passengers = new users Comfort = performance Driver = core system Extra seats = temporary resources Share-Auto Concept = Scalable System It increases passenger capacity while keeping the ride smooth. Just like multiple passengers share the auto, multiple users share computing resources. The system must scale horizontally (adding more autos/servers) or scale vertically (making one auto bigger/more powerful). The challenge is to keep the ride smooth for everyone, no matter how many join. Issues to Address (Tech Analogy) Each new passenger should be co...

  Learn & Share Online Brainery -  It was an e-learning platform for Computer Science courses. There were 4 courses published in the platform. I have launched a YouTube channel since May 2021. Check my post about the channel:  https://letussharehere.blogspot.com/2021/06/youtube-channel-learn-share-brainery.html Since, my concentration has been on YouTube Channel, I was not able to prepare courses for my platform. So, the platform was closed on August 2021.  My courses are converted to eBooks under similar titles. Check the link below for more details on my ebooks.

Present Education System Hope we are all aware of the path that we and our ancestors traveled! The present education system did not emerge in a single day. It had many efforts and many hardships!  It is quite easy to say that the present education system is wrong! But think for a moment! Before 2 years, Education system stressed class 12 and class 10 will have board exams. Did the system say class 12 students have to be trained from class 11 or class 10 students have to be trained from class 9? No where it is a written rule! When school managements stress this training, the teachers have to take additional responsibility in teaching the basics needed. Just for an example, class 11 in physics has thermodynamics - part 1 and class 12 in physics has thermodynamics - part 2. How come someone teach the second part of a subject without the first part?  Parents need to think! Do not select schools which gives training to entrance exams from kindergarten! Your c...

I had to visit this site for a purpose:  http://tnschools.gov.in/textbooks This site is Tamil Nadu State Government's website on the ebooks of Class 1-12 (available on both english and tamil medium). This syllabus is followed by Pondicherry too. So, whats there in this? I am a Computer Science graduate and hence it was out of curiosity, I had downloaded 11th and 12th computer science related books. (1) Computer Science (2) Computer Application (3) Computer Technology Whether you are a UG or a PG student, does not matter. Whether you are a college faculty or IT related employee, does not matter. Whoever you are, if you have pursued Computer Science, in any of your academic period, kindly have a look! I am yet to go through! But it may take a lot of time to complete at least to skim the content! Let us not miss to know what the book has!

There are 2 approaches for taking up and carrying out a research work in any field irrespective of any factors related to it: (1) Top Down Approach -  It starts from a broader perspective where you have no idea on what to do and at later stages narrows down to a problem definition.  Select your domain Select your area of study Select the topic that interests you Get updated information on whats happening around the topic Prefer a particular concept Dig more on what research aspects are available on the concept Think of a problem  And continues the next stages of a research work (as it is on a thesis contents page). Until you reach the last stage, you really don't know what to do. Once you trace it out, you start finding how to do. (2) Bottom Up Approach -  It starts from a single problem / task that runs in your mind often or you come across then and there. Some problems wont have a definite solution, while the others don't have so...
