Developing software in one's spare time is also a learning process that can (and usually does) further one's career. You seem to imply a developer shouldn't work on a programming task unless they're paid for doing it. I assume you're not a developer?
I am a profressional developer, that's why i don't have spare time. and when i do have spare time i generally have more either more fun things to do, or more profitable ventures - either way i do not code (especially) for *fun* - that's for junior guys who either need brag to others how many hours they work/code a week, or inexperience enuf they haven't done this enough number of times. wake up dude
Gosh, especially so ... *learning* new API or platform or paradigm which does same thing over and over again perhaps with slight improvement. That's just waste of time don't see much creativity in this can't figure how people get so excited do this sh*t.
no problem dude - don't eye on experience. Experience don't sell in Asia. You should be very careful how you spend your time. Working countless hours of unpaid overtime or Open Source (Don't get me wrong, I use Open Source thanks very much) is one best way to find out when you're age 40 and don't have a house or can't afford your parents' retirement.
Silicon Valley is the last place on the planet where they pay a developer more than any non-skilled jobs in USD150k range (even then it's much lower than doctors/fund managers/lawyers and any *respectable* trades). High paying dev jobs in Asia is practically not existent, especially general IT/consulting projects.
Your only way out is work for investment banks but you'd soon find that traders throwing darts at random will still make more than you do.
Instead of wasting your time learning countless numbers of new API's and framework or work for a sweatshop, you'd do yourself a big favor focus on things that matters - may it be algorithm which offer unique capability, or run your own gigs
Programming don't pay - product and sales does. Coding for nothing is the ultimate un-cool endeavour I can ever imagine.
