Re: [Discuss-gnuradio] Seeking mentor in GSoC

[Martin Braun (CEL)]

Hi Gong Zhang, (and other interested students),

you don't *need* a mentor to put in a proposal for GSoC.
This is how it works:

- You write a proposal and submit it to GSoC
- We consider all proposals based on their quality, impact on the
  project, feasability (and, let's be honest, what we think is cool)
- If a proposal is accepted, you *will* have a mentor. We'll take care
  of that.

Now, back to your idea. Because you've brought up your own project,
(and that's a great thing, nothing more important than initiative in an
open source project!) there's no default person to discuss it with, and
the only other way is to discuss it here, on the list.

As I've written before (off-list), I'm not 100% clear what your project
entails. You should to the following: Think about what exactly your
project should look like, what your milestones and deliverables could
be, specific examples for scenarios where your tool would be useful, and
how it justifies 3 months of full time work.
Then bring that back up in this thread.

On a side note, I'm happy that you're interested in participating in
GSoC, but you would have helped everyone if you had brought up the idea
earlier!
