Server Sky presentation, with Personal Telco folks, tomorrow in PDX at 6:30pm

The following email just dropped into my inbox, and I had to share. Keith is a fixture in the Portland tech community – running Linux clinics (scroll down the page for info), volunteering at FreeGeek, attending user group meetings and occasionally presenting.

He’s got this crazy idea – provide computing services from orbit. It involves ultralight discs of silicon, solar sails and launching “stuff” into orbit from a really long rail line.. and, well, some other completely awesome ideas. Keith set up a wiki, and there are great volunteer opportunities sprinkled throughout it, like “Study and simulate the trajectory and recovery of a tumbling server-sat in detail.” Seriously.

If you’ve got some time tomorrow, you should go check it out, have a beer at Roots and mingle with the Personal Telco folks, who are amazing for creating a completely free, volunteer-driven wireless network throughout Portland.

Tomorrow’s meeting at Roots Organic Brewing will feature a talk by
Keith Lofstrom about ServerSky.

See you then!

Chris Chen

For Pluggers that don’t know, The Personal Telco Project is a brave
band of wireless warriors, unwiring Portland one free hotspot at a
time. A great way to give back to the community, learn about wifi
and Linux and neat gizmos like the ALIX SBC, and hang out with the
Cool Kids. The monthly meeting is a great chance to “network” 🙂

Server Sky is a proposal for array computing and internet service
from orbit. We are building a team of technically savvy dreamers,
then will recruit local manufacturers (Solar World, Intel, Triquint,
etc.) to build it. If you can do radios, math, physics, coding, or
even drawing or gardening or salt-water coral aquariums (!) we can
use your help.

Someday, we will feed the PTP ground mesh from the multivendor
orbiting mesh, and no longer depend on ground monopoly backhaul.

I’ve given versions of this presentation before. This is somewhat
improved, and I will be presenting it next week at the A.I. Meetup
in the Bay area, Lawrence Berkeley Labs, the Hackers Conference,
and a few other venues.

GSoC Mentor Summit and the new mentor’s manual


I’ve been in San Jose since Wednesday, working on a book and preparing for today’s Google Summer of Code Mentor’s Summit. We’re here at Google’s campus, setting up the schedule and meeting new and old friends.

A group of us – me, Jen, Alex, Bart, Jonathan, Leslie and Olly – worked with Adam Hyde from to create a new GSoC mentoring guide. We “book sprinted”, writing the entire manual in two days. Leslie was nice enough to produce printed copies for attendees, and the whole thing is available online at: is pretty cool — you can create epub books, PDFs and beautiful looking printed books quite easily.

I was happy to reference the patch review process from PostgreSQL in the ‘upstream integration‘ chapter.

We’d love comments, feedback and contributions to the manual!
