Awesome donations for the mesh today! Thanks to J Rad for the cable
and the generous cash donation, and to Daniel and Novato School
District for the server!
Notes reposted for posterity at

=Updates=
*We now have a ~18 TB server! Thanks to Novato Unified School District
for the donation and Daniel for coordinating! RAD@!
*J Rad dropped off 1000ft of outdoor ethernet cable and $600! :o
*Marc is building a spectrum analyst machine from an OLPC + an
omnidirectional Bullet, a GPS, and portable power supply -
https://sudoroom.org/wiki/Mesh/
*Marc solved the MTU issue! (rearranged the layers :)
*Daniel spoke with a landlord who's interested in supporting the project.
*Jeremy spoke at SF New Tech on Monday! We should hack more startup
events!
*Marc's been testing the cheap TP-Link routers and made a firmware
image (minimal OpenWRT) that's a tarball that can be unzipped right
onto the router. Unfortunately, the cheapest ones are not approved by
the FCC. However, he found a bunch of better routers (eg; Western
Digital) for around $27 (plus a USB stick would be ~$35)
*Jenny presented the mesh at the Mass Effect event last Friday:
https://sudoroom.org/wiki/Mass_effect
*Upcoming EFF event in Berkeley (including Daniel Ellsberg) on Jan.

*As router resellers, we'd be responsible for replacing them when they
break.

*https://github.com/richo/groundstation - Project used by Byzantium
folks. From The Doctor: "It is a distributed Twitter work-alike that
uses Git for its back-end and a lightweight gossip protocol to
synchronize other instances on the network. It presents a regular
HTTP front end (which is easily proxyable through Apache to add
SSL/TLS for data-in-motion protection) and does not require that users
create accounts to use it. Communication channels are set up on the
server side, and users can interact with (read, post, comment) with
them from the client side."

Pete and myself Installed a nanostation m5 on a 20 foot aluminum flagpole in west oakland. The node is about 14 feet above the roof of a two-story building. The total cost of this install ran to about $145 including all materials.
Bill of Materials:
* One nanostation m5 loco
* One 4 foot wood beam of 3.5" by 3.5"
* Three 5" by 1/4" bolts
* Three 5/8" washers for bolts (optional)
* Three 1/2" washers for bolts (optional)
* Two 5" hose clamps
* 30+ feet of outdoor shielded ethernet cable
* Two shielded/groundable ethernet plugs
* A bunch of zip ties
The optional washers make it easier to tighten and untighten the bolts (otherwise they dig into the wood).
Material sources:
* Nanostation from Amazon
* Flag pole from habor freight
* Everything else from home depot

They had 60 seconds at the end of the night to pitch an idea. I wasn't very
prepared but I mentioned the People's Open Network. The whole stream is
available online. ustre.am/UknO <http://t.co/K4lwq0YEos> There's a feed on
twitter too (#sfnt), I'll apply and see if we can get a full segment there.
Hi!
Ubiquiti in point-to-multipoint configuration performance is really bad
with current open source OpenWrt ath9k drivers. Ubiquiti has TDMA
implementation and that works very very well. Using that for backbone
links is really great. But, sadly it is closed source and now that one
cannot use their SDK anymore to customize firmware we are stuck in good
and cheap backbone hardware.
Is there anybody who would be able to implement TDMA into open source
drivers?
