Tonight we discussed trying two new things for February:
- Having a formal session where one member presents to the group,
followed up by Q&A, and some general functional hacking fun. We'll try
and do this the first Wednesday of every month, and the drinkups the
third Wednesday of every month.
- A minimalist formalism of scheduling presentations such that members
post describing their presentation. We use replies to the presentation
threads as a gauge of interest, and the presentation in the queue with
the most interest gets done.
I am up for presenting on Clojure's concurrency types owing to
Blaise's prompting and general curiosity. Subjects I will be covering:
- Programming with values
- State vs. Identity, the foundation upon which Clojure's concurrency
primitives are built.
- Refs: Coordinated, synchronous identities.
- Atoms: Uncoordinated, synchronous identities.
- Agents: Uncoordinated, asynchronous identities.
- Vars: Localized identities.
I'll come up with some contrived examples that are slightly less
contrived and slightly more compelling, by my own judgments of
compelling and contrived, than in 'Programming Clojure' or 'The Joy of
Clojure'.
They'll still be rubbish, though.

Blaine, not Blaise :-)
Totally interested, though I realized that 1st Wednesday is a week from now. Are you comfortable with that or should we push it back?

Also, I think I can rig up a recording solution with my point-and-shoot, a lapel mic and my guitar amp.

:-) Sounds like a good talk. I hope I can make it for the next presentation!

Yes, I'm looking forward to the talk.
Gary, thanks for the name correction. That said, I thought it sort of
a happy accident. Blaise is cooler than Blaine for a number of
reasons.

Yes, I wish I could be mistaken for Pascal, but no such luck :-)

I've been contemplating and researching it since December, so it's
mostly just a matter of setting up the presentation. Which shouldn't
be too bad. I'll make some example clojure source that will (on my
machine) demonstrate how the concurrency types can ensure correctness.
I'll also try and generate some comparison cases to highlight how they
compare against each other.

Also let's announce this one, along with the location, some time today
to give people a heads up. :)

Yea, we'll be good to go. Been working out the details in the back of
my mind, I'll put up an announcement promptly.
