I’ve been selected as Google Summer of Code 2018  mentor for Apache Software Foundation  as like last year.
Google Summer of Code (GSoC) is a global program focused on bringing more student developers into open source software development. Students work with an open source organization on a 3-month programming project during their break from school.
You can check GSoC ideas of Apache Software Foundation from here: https://issues.apache.org/jira/issues/?filter=12343065 and create a new one if you have any other.
Student application period will be between March 12–27, 2018 . I suggest starting to warm up with communities before the start of the application period.
