The announcement email from Ivan Tarasov:
Hello, fellow Haskell enthusiasts,
Paul Higham proposed to give a talk about Gray codes at our June
meeting: In general a gray code is a cyclic sequence of words of the
same length, where any two successive words in the sequence differ in
exactly one letter position. The most commonly-known of these codes
was used in the patent application by Frank Gray in 1947 of a method
for analog to digital conversion. The code has a number of
engineering applications, but is also interesting for its mathematical
Knowing Paul's attention to the interplay of the mathematical aspects
of things he's working on with Haskell, I expect the talk to be
extremely interesting. In case you want to brush up your maths before
the meeting, you can take a look at Wikipedia article on gray codes.
Nevertheless, I'm sure Paul will do a great job explaining everything
during the talk.
The meeting place is our usual place in SoMa, kindly provided by Engine Yard:
500 Third Street, Suite 510
San Francisco, CA 94107
Contact phone (mine): [masked].
Host's phone (Larry's): [masked].
Please arrive a little bit earlier, so that we could start at 7pm sharp.
We may try to set up the video feed through Google Hangout (I will
post a public link in my G+ before the meeting starts if we succeed in
setting it up), however please don't rely on it and try to visit the
meeting in person if possible. If you are going to be joining the
hangout, please mute your microphone before you join.
Some people will be going from the South Bay (and probably East Bay)
to the meeting and back, so there's a possibility of carpooling. Also,
it's very easy to get to Engine Yard from the Caltrain station (4th &
King Str) and Embarcadero/Powell BART stations. Please send me a
message if you need help figuring out transportation. If you are
driving and can take some people from East/South Bay to the meeting
and back, please send a message to the [masked]
