An online programming contest to mark the celebration of Ada Lovelace Day was held on 12th October 2016. Ada Lovelace Day (ALD) is an international celebration day of the achievements of women in science, technology, engineering and maths (STEM). It aims to increase the profile of women in STEM and, in doing so, create new role models who will encourage more girls into STEM careers and support women already working in STEM. Founded in 2009 by Suw Charman-Anderson, it is now held every year on the second Tuesday of October. This year the day was celebrated on 11th October.

To celebrate the day, BdOSN organized an online programming contest for the girls. The contest was held in the online judging platform Codemarshal. The contest was participated by 256 participants. Although the contest was intended only for the girls but few boys also participated in the contest. Out of 256 participants 167 solved atleast 1 problem where as top 13 girls solved all six problems. The problem sets used in the contest were developed in the mentors camp held recently.
