CFP: Celebrating 40 years of GNU in Biel/Bienne

[Christian Grothoff]

Dear all,

We are calling for proposals to present at the 40 years of GNU 
celebration and hacker meeting on September 27th in Biel/Bienne 
(Switzerland): https://www.gnu.org/gnu40/

Please contact gnu40@gnu.org with ideas, and of course please save the 
date! We will post a larger announcement once we have a bit more of a 
program.


Happy hacking!

Christian
