It is now almost four months that I have shifted all my courses online. I have been getting a lot of queries about the methods and the learning process experience.   I decided to compile essential questions and formulate an FAQ for the same. I have posted these FAQs on the Site's Inquiry Page. Inquiry page

This happens sometimes... that a poetry visits my mind. Life. It's the present that I ride,  to the land where the future resides, with past as guide and hope my light.

If I ask Chotu how much time he will take to eat ten grapes, he will typically say a few minutes.  If I ask the same question to his digestive system, then the answer maybe a few hours. The answer depends on who is answering and what eating means.  For Chotu, it is chewing,  gulping, and relishing their taste. Chotu also rejects peduncles, cap stems that come with grapes.  For his digestive system, chewing would mean breaking down and converting grapes into its ingredients, and gulping would mean incorporating them in blood, and rejection means excretion of the non-essential.  As I see it, eating is of two types Deep and Shallow. Usually, what we call eating is in this context, Shallow Eating, and digestion is Deep Eating. Both are essential for survival. When we intake Knowledge, we go through a similar process. The Shallow Eating part is akin to reading books, watching videos, attending seminars, among other things. The metaphorical grapes have gone inside our system.  I would label

It has been a testing time since COVID Pandemic. Many established Professions, Institutions, Industries, and Systems are adapting to the new reality. Education is also changing itself. It's been almost four months that I have not conducted a lecture in a Physical Classroom. I have sifted Online wholly. I want to thank Google, especially for it's Google Meet. All my courses stalled due to COVID, and the new ones just launched are now normalized. I have occasionally been offering Video courses to a restricted audience, but now my classes are available internationally. I am happy that I can teach students from UK, USA, Canada, Dubai, Delhi, Rajkot, Bhopal,... And of course Mumbai, all together in a batch.  Although international students have been attending my courses, they had to participate in my classes physically. The flexibility of Online arrangement is liberating. Some new facilities in Online Courses Registration through email Payment is possible through any form of

Enjoying REPL with Java 10. Introduced Java10 in the ongoing Java Technology Batch. Also playing with *.jsh files. Sample Program ( piggybank.jsh ) import static javax.swing.JOptionPane.*; import static java.lang.Integer.*; var balance = 0; var lt = 0; void statement(){ showMessageDialog(null,"Balance = " + balance + "\n"+ " Last Transaction = "+lt); } void deposit(int v){ balance = balance + v; lt = v; } void withdraw(int v){ if(balance >= v){ balance = balance - v; lt = -v; } else{ showMessageDialog(null,"Insufficient Balance"); } } statement(); var sr1 = showInputDialog("Enter amount to deposit"); var r1 = parseInt(sr1); deposit(r1); statement(); var r2 = parseInt(showInputDialog("Enter amount to deposit")); deposit(r2); statement(); withdraw(parseInt(showInputDialog("Enter amount to withdraw"))); statement

Conducted a small survey on twitter regarding the inheritance related open decorator  in the Kotlin language .  The comparison was between the design semantics offered via Java's final keyword and Kotlin's open keyword. Here are the results. In Java every class by default is inheritable until made final. In Kotlin every class by default is not inheritable until annotated with the keyword 'open'. If you were to create your own language which approach would you prefer — RajeshPatkar (@RajeshPatkar) November 14, 2017
