Hello everyone, After receiving feedback and suggestions from all of you, I am modified and refined my application and incorporated all your ideas.I request you to please do read the proposal and provide feedback to the updated proposal since the date is closing in. I have linked the GSoC proposal below.
Thanking you, Regards, Suraj Hanchinal GSoC proposal : https://github.com/surajhanchinal/GSoC_proposal/blob/master/My%20GSoC%20Proposal%20.pdf On Sun, Mar 25, 2018 at 8:37 PM, suraj hanchinal <[email protected]> wrote: > Hello everyone, > Thank you JM Friedt.
