I have some questions since last couple of years. Here I
want to ask you now. If it is possible for you, kindly
answer my question.
1. What motivate or inspires you for working in an open
source project, when you can spend that time too in
commercial purpose ? (I supposed that, because of your
higher level of expertise)
2. What approach did you follow, when learned to code at
young age and how you became so skillful in programming?
3. Should I need to learn framework or I can survive well
if only know good programming in a popular language?
4. How to stay motivated for long amount of time in
learning programming?
5. Do you drink coffee and whether it has any negative
effect or positive?
6. Last Question for now is, why IntelliJ IDEA's code
completion is blazing fast? (😋Don't mind, I have an
opportunity for using IntelliJ IDEA's ultimate edition,
but still I love to use NetBeans for its simplicity, open
source nature and some other unknown reason.)
