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? (๐Don'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.)
