We had a really interesting meet where all Julia Summer of Code applicants were called to. There were some really superb people too, like Chris Rackauckas.
Chris is a really interesting person. He gave some really meaningful advice in the first session itself. Some bits from what he said -
Commit code every single day.
Be public in your conversations.
Interacting with people is of utmost importance in open-source software (I experienced this first hand).
Share (via blogposts or alike) as much as possible, your work.
I met him today again in the JSoC-autodiff meet (the name says it all - it was a meet for all autodiff projects). We introduced our projects, and the other projects which were mainly driven by Differential Equations just went bouncer for me. When I introduced my project, Chris said he just goes blank when there is anything associated with images, and he can handle equations much better (in a fun tone). Seemed like something unusual for him to say, but nevertheless, I would love to work with Chris sometime in the near future.
