On behalf of all the contributors, we are pleased to announce that the
Haskell Communities and Activities Report
(27th edition, November 2014)
is now available, in PDF and HTML formats:
http://haskell.org/communities/11-2014/report.pdf
http://haskell.org/communities/11-2014/html/report.html
Many thanks go to all the people that contributed to this report,
both directly, by sending in descriptions, and indirectly, by doing
all the interesting things that are reported. We hope you will find
it as interesting a read as we did.
If you have not encountered the Haskell Communities and Activities
Reports before, you may like to know that the first of these reports
was published in November 2001. Their goal is to improve the
communication between the increasingly diverse groups, projects, and
individuals working on, with, or inspired by Haskell. The idea behind
these reports is simple:
Every six months, a call goes out to all of you enjoying Haskell to
contribute brief summaries of your own area of work. Many of you
respond (eagerly, unprompted, and sometimes in time for the actual
deadline) to the call. The editors collect all the contributions
into a single report and feed that back to the community.
When we try for the next update, six months from now, you might want
to report on your own work, project, research area or group as well.
So, please put the following into your diaries now:
========================================
End of April 2015:
target deadline for contributions to the
May 2015 edition of the HC&A Report
========================================
Unfortunately, many Haskellers working on interesting projects are so
busy with their work that they seem to have lost the time to follow
the Haskell related mailing lists and newsgroups, and have trouble even
finding time to report on their work. If you are a member, user or
friend of a project so burdened, please find someone willing to make
time to report and ask them to "register" with the editors for a simple
e-mail reminder in October (you could point us to them as well, and we
can then politely ask if they want to contribute, but it might work
better if you do the initial asking). Of course, they will still have to
find the ten to fifteen minutes to draw up their report, but maybe we
can increase our coverage of all that is going on in the community.
Feel free to circulate this announcement further in order to
reach people who might otherwise not see it. Enjoy!
Mihai Maruseac and Alejandro Serrano Mena

Thanks much Kim, that was very helpful.

Friends
With each issue of the Haskell Communities and Activities Report I am freshly
awed by the range and creativity of the things you are all doing with Haskell.
From web frameworks to bioinformatics, from automatic differentiation to GUIs
and games. Amazing stuff.
I think we owe the editors, Mihai Maruseac and Alejandro Serrano Mena, a huge
debt for putting it together. Thank you!
Simon
