The 2nd Global Programmers' Festival has opened in the Xi'an High-tech Industries Development Zone, attracting numerous programmers from home and abroad.

Masako Wakamiya, at 83 the world's oldest programmer as well as an iOS developer, is attending the two-day event.

Wakamiya was born in 1936 in Toyko, Japan and worked as a bank clerk before retirement. She bought her first computer and started to learn programming after she retired at the age of 60.

In February 2017, the first game (Hinadan) Wakamiya developed was put on the App Store in Japan, and has been downloaded more than 42,000 times so far.

The game aims at users over the age of 60, and is inspired by the traditional Japanese Doll Festival. Its rules are similar to the festival tradition.

Wakamiya attended the Apple Global Developers Conference 'WWDC 2017', as the world's eldest programmer, receiving worldwide attention in June, 2017.
