Dang! I seriously just finished writing my copy, went to gmail to send a draft to Andrew and BOOM he's already sent his wrap-up.

(Turns out, I have no idea when the Germanian war that started in
17 AD ended, but if you happen to know, feel free to reach out.)
(Have a complaint about this email? Want to make it better, fix
a typo, or add more info? Fork the gist on GitHub!)
Thanks to [GetGlue](http://www.getglue.com) for hosting us! The
pizza was great, the drinks, they were sugary, and stickers oh so
Puzzle? Psshht! Puzzles take time to write, to do, and did I
mention someone has to *grade* them? Round 17 was too ad-hoc to put
that together, and the crowd that came would have aced it anyway.
I will, however, give you the answer to last month's wrap-upzzle:
(define (assoc dict key value)
(if (eq? k key)
(define (lookup dict key)

## Projects Presented (in pseudo-random order)
### [Braindump] Malcolm Matalka (all the way from Sweden!)
Braindump is back! That's right, America's favorite Meetup (which
shut down to free up more time for Hacker School) has turned into a
wee-wittle segment at Hack and Tell--but hey, it's something! Want to
do a Braindump? Send me 3 blood samples, $5 US and a self addressed
stamped envelope. (Or, ask next time there's a call for speakers.)
This month, Malcolm was in town for Hack and Tell^W^W^Wa wedding, and
braindump'd a bit about what he knows of phantom typing in OCaml.

### Nicolas Dufour
The Refuge Project aims to provide a fully decentralized and
open source data platform. What does that mean? Well, it means
that you'll have easy access to any data you shove into it.

### Grant Kot
Like Grant, I have like 3 words, awesome tentacle physics!

### Peter Coles
Peter showed off his pure JS/CSS/HTML5 piano, which generates WAV
files that are then data-URI encoded. In other words, only ASCII data
is loaded from the web server, the rest, as they say is magic.
The visualizations were a little bit primitive, but hey, I guess
that's what you get for studying Computer Science instead of cello at

### Zed Shaw
I mentioned during Round 17 that the reason Hack and Tell exists is
due in part due to the Freehacker's Union, which Zed created when he
lived in NYC. So having Zed stop by and see the community we've
created was certainly a treat.
These days Zed spends lots of time teaching programming by writing
books. They're freely available, but if you use them, and like them,
send him a few bucks so he can write more!

### John Workman
Need to load hundreds of pictures in a web browser, but don't want
to bog down the experience? Well, scrollstream attempts to solve
this problem removing things from the DOM that aren't visible, and
loading new items in when they should be visible. It's dynamism at

### Dan Vanderkam
Dan showed us dygraphs, an interactive, zoomable time series plotting
library for the web. It's pretty cool, supports oodles of data points,
has lots of tests *and* documentation. Really, it's like some holy grail
of software projects, which means if you have a use for it, you should
seriously consider it.
### Joschka Kintscher
Harvey allows you to do conditional JS loading via CSS media
queries. It has the concept of "Coins," which control how the JS is
loaded/executed. Personally, I'm just glad someone put a Dent into

### Aidan Feldman
Aidan talked about his JSONP proxy, which allows you to do JSONP with
*any* JSON API on the web. He could have saved himself some trouble
though, since the Meetup API supports JSONP. Nevertheless, it might be
useful for someone else!

## Announcements and things to watch out for
### Round 18 -- Coming soon!
Have something you'd like to present? Have something to Braindump?
Have a (free) space that can hold 80-100+ people and don't mind some
guests? We're starting to plan Round 18, so let us know if you can
help us out! Call for presenters coming soon!
### Hope Number 9
HOPE is invading Hotel Pennsylvania yet again. This time,
it takes place on July 13-15. For tickets or more information
## Wrap it up
That's it! Hope to see you all at Round 18!
Andrew and James.
: Wikipedia has been lest helpful. (but, I didn't really look
all that much... Yeah, my fault.
: Have a more clever solution in a language that doesn't *have*
closures? Share it!
: ... and this time it's personal.
