Ah - your day job isn't tech. Was wondering how you could get permission and time to do it.

Every tech job I've had here in SG expected full ownership of any and all IP created whilst an employee, no moonlighting, and always ended up consuming every waking second of my time anyway making the whole point moot.

Good on you for making it all balance and not only feeding your family but spending time with them too (which is bloody hard here).
