Happy Ada Lovelace Day

On Tuesday, Maia Weinstock, of Cambridge, Mass., a Brown University graduate, works on her computer during a Wikipedia “edit-a-thon,” on the Brown campus, in Providence, R.I. They held the event, which brought together dozens of people to train them on how to add and edit pages to Wikipedia, to coincide with Ada Lovelace Day, an annual observance started in Great Britain in 2009 to highlight women in technology and named for the English mathematician who died in 1852.
