Since going open source, Roslyn has had 45 and Visual F# has had 29 unique code contributors external to Microsoft. To celebrate and appreciate our first contributors, we sent them each a small gift in the mail: a mug with the classic “cup of tea” language joke as well as the SHA1 of their first commit engraved on the back of the mug.

Over the past six months, some of you have received these small tokens of gratitude and some of you have seen evidence of them on Twitter (#roslyn, #fsharp). Every contribution—no matter how great or small—warranted a fun surprise in the mail. We have been absolutely thrilled with the pull-requests we have been receiving (shout outs: BradBarnich, mrange) as well as the engagement on language design. We cannot thank you all enough for joining us on our exciting journey into open source.

This cup campaign was a team effort and came straight from the Roslyn and Visual F# offices to you. Let’s take a look “behind-the-scenes” (every step was done by our team!):

We’ve successfully sent 60+ mugs to contributors in 24 different countries, including: Australia, Austria, Belarus, Brazil, Canada, China, Czech Republic, Denmark, France, Germany, Ireland, Israel, Italy, Japan, the Netherlands, Poland, Romania, Russia, Slovenia, Sweden, Ukraine, the United Kingdom, and the United States of America. The last several mugs are on their way!

Now we are out of mugs so the team’s days of wandering down to The Garage to laser etch and send mugs off around the world are at an end. Don’t fret! The team is currently brainstorming new ways to recognize the work of our contributors and we cannot wait to see what awesome things we will build together. Thank you to our first code contributors; thank you, thank you, thank you! If you want to check out the buzz, see below:
