NERP Tonight — A Tor Relay Demo, and a Sketchy Update

NERP Tonight — A Tor Relay Demo, and a Sketchy Update
NERP is not exclusively Raspberry Pi, the small computer
and embedded systems interest group at Pumping Station:One
in Chicago. NERP meets every other Monday at 7pm at Pumping
Station:One, 3519 N. Elston Ave. in Chicago.

Drew has put together a Tor relay using (what else) a
BeagleBone Black.
( Tonight at NERP,
he’ll show us how it’s done.
From the Tor site:
Why Anonymity Matters: Tor protects you by bouncing your
communications around a distributed network of relays run
by volunteers all around the world: it prevents somebody
watching your Internet connection from learning what sites
you visit, and it prevents the sites you visit from
learning your physical location.
Use of Tor is often a sensitive discussion topic. In the
culture in which we live, there is no universal consensus
on where an individual’s right to privacy from governmental
and corporate interests ends and the larger interests of
security and commerce begin.

Tor is a tool that aims to provide user and location
anonymity on the Web. Anonymity can foster good, bad, or
indifferent ideologies and behaviors. In some contexts
anonymity can even be seen a sort of power similar to that
of a firearm. There are those who would question “a priori”
why a person would insist on total privacy unless they had
something to hide. From this perspective, using a privacy
tool is in itself suspicious. Others feel that privacy is a
basic need of human individuals, and therefore an
inalienable right. At the end of the day, technology itself
isn’t human, isn’t alive, and can’t think or feel; it’s
totally indifferent.

In tonight’s presentation we will try to stay focused on
the technology behind Tor. It’s counter intuitive to me at
least, how anonymizing technology is practically possible.
How it’s done will be an interesting study in some
non-obvious applications of low-level network programming.

Also tonight, I’ll be giving another update on development
of “Sketchy”, the network controlled servo-powered
