Enormous Changes to Google Summer of Code in 2015


The Google Summer of Code (GSOC) is a progam that has helped many open source projects. Google accepts applications from projects and provides up to $150,000 in stipends to help student developers contribute code.

Since it started in 2005, Google estimates that GSOC,

has brought together over 8,500 successful student participants from 101 countries and over 8,300 mentors from over 109 countries worldwide to produce over 50 million lines of code.

Last year, there was a 10% increase in the program to commemorate its 10th anniversary.

This year, there was been far more significant decrease in the size of the program. The number of accepted projects dropped from 190 last year to 137 this year – the lowest number for many years.

After seeing reaction to the news on Twitter, I compared the list of accepted projects in 2015 to the list from 2014. It appears that over 130 projects were dropped and over 80 new projects added.

Some the biggest names in open source weren’t accepted this year, including Mozilla, WordPress, the Linux Foundation and the Tor Project. There’s also a smaller group of exciting new projects that are getting GSOC support for the first time.

What are your thoughts on these changes?

First, apologies if I made any errors in comparing these too lists – I probably missed one or two. Please feel free to correct me in the comments.

Second, I can’t see any clear patten to which projects were accepted and which weren’t, but let me know if you can.

I’m obviously sad that Joomla didn’t make it – but I’m also glad for all these new organizations. I’m looking at the list of new organizations, and see amazing organizations focused on everything from environmental issues in Africa, to collaborative coding, and web security, all with open source code. I’m glad these organizations will get a boost, they definitely deserve it.

Well said, Jon. If there’s a pattern, that’s probably it – Google wanted to bring on board a whole lot of fresh faces.

LLVM Compiler Infrastructure seems to be in both lists. I can’t speak for the others, but I believe The Perl Foundation just ran into some logistical issues so they weren’t ready in time (ie, if there is a pattern, they won’t be a part of it).

Thanks for catching that, Kevin, and for the Perl update.

Great post, but I noticed that the Nmap Project is in both your lists when it shouldn’t be in either. We’re in what might make for a great third list of orgs which participated last year and are grateful and happy to have been accepted this year too!

These lists are faulty. For example, Clojure participated last year. X.Org, syslog-ng, Python Software Foundation all got accepted.

Bookie did not apply this year, as we are swamped with other commitments. Just clarifying that it wasn’t Google’s decision this year.

Thanks Craig. Yes, I think that’s true of several organizations, including WordPress and Perl.

At least FOSSASIA, LibreOffice, Privly, Tox, Wine and X.Org were in 2014 so you might want to go through that first list again.

Thanks Beluga – I fixed 3 of that list that were mistakes

Great list Steve, only think I spotted was Sugar Labs being in both lists.
