He emerged as the organic intellectual of the Occupy movement, and has made important contributions to the renovation of antinomian thought. Among his books are Fragments of an Anarchist Anthropology, and Debt: The First 5000 Years.

Tuesday, April 2nd 7-9pm Room 607 "Art, activism & politics of stereotypes: a "Gypsy Show'" with Sani Rifati Please join us for a talk that will focus on Roma history, music, and culture. Despite the recent attention, or even hype, surrounding the cultural production of the "Gypsies," vast majority of Roma artists can barely make a living, let alone enter the world music stage. Brands that we usually associate with this culture, "Gypsy Caravan" and "Gypsy Spirit", are more often then not far removed from the actual existing Roma culture and contexts of racist violence unfolding in Europe. Come and celebrate International Roma Day, in solidarity with Romani struggles for dignity and internationalism. ****************************************************** Anthro & Social Change Department sends out occasional messages regarding our public events.

May 1st - Dance + LED performance at Bekreley Museum

by Romy Ilano

https://sudoroom.org/wiki/page/DanceSound Hey Sudoers *May 1st the choreographer/dancer teacher from the public school is having a performance at the Berkeley Museum of Art.* * * *Anyone interested???* - She is open to lights. Rachel would you be interested in showcasing your wearable electronics? We have to wear all white. - I would love to see Rochambeau do something creative and weird with video and music. - Anyone interested in doing lighting? How can sudo room people do things creatively that go outside of what is expected for such a performance? *For me, I'm focused more on the creativity of the members of sudo room. Showcasing private companies' work if they are not members of sudo room is less appealing than showcasing the work of a sudo room person.* Note also that this is the choregorapher's perforamnce. She is doing something with sound involving tonality rubbing a big metal bowl with a finger... Best, Romy

Sudo Room is Open + New Sudo Room Title: Keymaster

by Andrew

Hi All, Sudo Room is open. I'll be here until someone joins me to hold open the fort. Also I'd like to propose (and immediately implement) the title of "Keymaster": *A "Keymaster" at Sudo Room is dedicated to the open and public access of Sudo Room. A Keymaster will make it their mission to understand, maintain and utilize the tools needed to open Sudo Room and keep it open for members and soon to be members. A Keymaster will distribute access in accordance with the values of Sudo Room.* I would like to anoint my self a Keymaster. If you'd like to get in to the space and you don't know how, come see me. or call/text me 831-332-2507 . I am one human solution to the technical issue of access to Sudo Room. PS. I tested RFID and Sudo Door wifi, both are working. --Andrew -- ------- Andrew Lowe Cell: 831-332-2507 http://roshambomedia.com

Re: [sudo-discuss] Birds trapped in sudoroom

by Yardena Cohen

The birds are now "safely" outside. I cleared a very obvious path to the window and Matt laid bread crumbs on the floor. Then we closed all the doors and left them alone for a while. When I came back in, they were already close to the window, and I saw them fly out. I think they were fleeing from me. Good luck, little birds!

ladies of sudo at a women in tech event for a cool danish company that's into communal DIY?

by Romy Ilano

Hey ladies, Someone slap my wrist if this is too commercial-(i'm sure i'll get spanked)-but I'd love to have any technical women who code and hack stuff like Jordan or Vicki (google glasses) meister be my dates for a Women in Tech event held by a Danish b2b company Tradeshift. They're all into hackerspaces and communes. Their CEO was all over the Danish BBS scene and is a hacker himself! This is this Wednesday evening -- if you code and are into international networks, it would be so interested. My selfish motivation is that I'd just love to see more women who actually code and aren't afraid to get their hands dirty with embedded systems at these internatinoal events, not just marketing babes who look sexy in heels. Best, Romy

posting to sudo-announce

by Matthew Senate

Hey all, I've set full moderation on sudo-announce, so if you'd like to post, please say so on sudo-discuss first, then a moderator can approve your message to sudo announce. This way we won't have accidental multi-message threads spamming the announce list. Over time, we'll grow the number of moderators, and ensure we send Announce messages only when we mean to--and not accidentally.

Sudoroom welcomes Noisebridge to their new Oakland location!

by Yardena Cohen

Sudoroom would like to formally welcome Noisebridge to their new location in downtown Oakland, across the hall from Sudoroom! We think it was a wise choice to save on rent by moving to the east bay, and look forward to exciting future hacker collaboration. As you might know, Noisebridge has struggled with rising rents, at the same time that Sudoroom's landlord has struggled to find tenants. This was the perfect fit! Noisebridge is still only 1.5 blocks from BART, just as it was in San Francisco, so the extra commute should not be much trouble for anyone. https://sudoroom.org/sudobridge-a-financial-imperative/ https://sudoroom.org/wiki/page/Noisebridge

The [physical] finance dropbox...

Wifi door access and label printing working again

by Marc Juul

Hi sudoers! = wifi door access = Yardena recently fixed one of the issues with the door access (ram usage), and I just fixed the issue related to the wifi door access sometimes failing. If the web page doesn't come up automatically when you connect to the sudodoor access point, then go to your web browser and try to load any HTTP web site. If you try to load an HTTPS website, then it won't work. = label printer = The label printer has been re-loaded with new paper (thanks to tunabananas for buying!) and the software has been configured to hopefully be more stable and automatically start if the computer is rebooted. -- Marc Juul

Fwd: Re: robotics: 2-axis pointing

by hol＠gaskill.com

didn't get much of a rise out of sudo-doscuss... steve i have a 2-axis compass chip that is earmarked for rover use. excellent point about the cloudy day problem - i gave derek my paired arduino/processing utility for passing servo instructions from PC to microcontroller and my understanding is that he is going to port the PC side to python using the GPIO pins of a raspberry pi for serial connection with arduino to do the low-level actuation since it runs at 5V like servos and some ICs, with the end goal of pointing a webcam. I will take a look at your code when i get back to town and try to find a schematic for driving those HVAC servos. we can fabricate whatever mount we need, but for starters it looks like we could get away with some 1/2" or 5/8" square tube through the servo, with holes drilled for attaching plywood to which we could duct tape some small panels (i have 2 5-watt car charging panels for testing purposes). any interest in sensing the battery voltage and having the computer enter sleep mode during the night? Not sure how to do that on the rpi but there's some documentation for the arduino. The whole rpi could be turned off and on with a single power transistor, as could individual transmitters ------------Forwarded message------------ From: steveberl(a)gmail.com Date: Mar 31, 2013 09:29:23 AM Subject: Re: robotics: 2-axis pointing To: hol(a)gaskill.com Cc: patrikd(a)gmail.com, sudo-doscuss(a)lists.sudoroom.org On Sun, Mar 31, 2013 at 9:07 AM, Steve Berl steveberl(a)gmail.com> wrote: I've already got the "calculating the daytime paths" part.

For a portable or moving, rotating platform, you need a way to know the orientation of the platform, which might be a magentometer, or even better, a 9DOF IMU like https://www.sparkfun.com/products/11486 Dithering around the sun would probably be OK for solar panels, but on cloudy days, it might spend a lot of time hunting for a peak that doesn't exist.
