dli naman kelangan na ma 'disturb' ka while nag code,
as far as i KNow, you dont need too much concentration in coding?
why you say?
because coding is just typing words and syntax into IDE.
The time that you need to think is DURING DESIGN phase, if planado na tanan nmo the algo, architecture, etc.
THEN bsan pa nagatubang ka sa TV nagsubay, mahuman ra ghapon na nmo.
Remember that programming is 40% coding 60% design/planning.
I code my games and engine while infront of a TV. and trust me doing a 3D game engine needs math, trigo, physics and a careful architectural design, but all of those where already figured-out before writing the code so a little concentration is needed
therefore, dli mo matter if gabii or buntag ka aslong as your ready to write your code.
