While the rest of the Sri Lanka slept peacefully, a considerable number of young and enthusiastic programmers gave up sleep this weekend – but for a good cause. Anyone dropping in to the WSO2 offices in Colombo the early hours of Saturday or Sunday morning would have been greeted by the sight of exhausted but determined coders hunched over laptops, tapping away. Among them were three teams working on a problem put forward by LIRNEasia. This was the scene of the Code4good hackathon which started on Friday evening (18th) and ran non stop until Sunday evening. Though the intense work happened this weekend, preparation began much before.
