When Aengus and Dimitry Tran were growing up in Ho Chi Minh City, one of the family’s most treasured possessions was a computer. Sent to their father by an uncle who lived in France, it was one of the first computers in Vietnam. Their parents were high school maths teachers and, armed with this new possession, their father taught himself programming.

“He wrote the first programming book in Vietnamese, ever,” Dimitry tells The Australian Financial Review Magazine. “In our office, there’s a photo of my mum with Aengus as a baby next to our precious family computer – one of the most valuable things we had as a family.”
