[Critical] Need Potential Delegates for Omni Collective Participation

by Matthew Senate

Hey all, FYI - I've BCC'd you if you are a current sudo room member. Our current acting delegates to the Omni Oakland Collective, Yardena and Jenny, need serious relief. *PLEASE RESPOND IF YOU ARE CAPABLE OF ACTING AS A SUDO ROOM DELEGATE IN THE NEAR TERM. WE NEED YOU.* Patrick Xu has stepped up to act as the delegate for the next two Omni Meetings 9/25 and 10/2. We need more folks who can prepare to act as delegates in an on-going basis, as well as folks to act as delegate in the very near term on: 10/9 10/16 10/23

Fwd: [Mesh] Sudo Mesh meeting tonight and summer's end update!

by Matthew Senate

Folks, Please rejoice in this amazing update by Jenny Ryan on the progress of the Sudo Mesh project launching the People's Open Network: ---------- Forwarded message ---------- From: Jenny Ryan <tunabananas(a)gmail.com> Date: Thu, Sep 25, 2014 at 12:05 PM Subject: [Mesh] Sudo Mesh meeting tonight and summer's end update! To: "mesh(a)lists.sudoroom.org" <mesh(a)lists.sudoroom.org> It's been a crazily active summer - apologies for the lack of updates! Sudo Room (and by extension, Sudo Mesh) has relocated to the Omni Oakland Commons <http://omni-oakland.org> at 4799 Shattuck. We're excited to be a founding member collective among an array of groups that have moved in together to create a radical commons in Oakland.

list of lights and their wattages at The Omni

by Jake

I think it's important that everybody understand that electricity is sold in kilowatt-hours. This means that even a maximum-power electrical appliance like a toaster-oven used to toast food uses less power than a single ordinary lightbulb left on all the time: toaster oven: 1500 watts, used 30 minutes per day (0.5 hours) = 0.75 KW/H (12.75 cents per day, $3.89 per month) 60 watt lightbulb left on: 60 watts, 24 hours per day = 1.44 KW/H (24.48 cents per day, $7.47 per month) the big ovens might be 3000 watts, maybe 5000 watts, but you see my point. electric water heaters are definitely something, because they are maybe 4000 watts and are on for a total of a couple of hours per day possibly. we do not need to worry about anything that is only on for a short period of time, such as tools or ovens. We do need to worry about LIGHTS LEFT ON. Anything left on all the time will cost us money. Here is a list of all the lights I encountered on a walk around the Omni. lights 17x f96t12 (1275W) downstairs (all on, 2 people) 10x f40cw (400W) basement lawlibrary (on, no people) 1x ccfl (14W) southeast lower stairwell (good for safety) 12x6 25W (1800W) chandelier bulbs in ballroom (off) 2x F96T12 (150W) + 23W ccfl + 15W ccfl near entrance (CCFLs were off) 1x ccfl (23W) outside entrance (was off) 17+18x F40CW (1400W) barroom (all off) 2x 23W ccfl (46W) kitchen (always on) 3x 96W refrigerators, (287W) mostly empty (all plugged in) bulb rope light on floor, (50W) (always on) 1x ccfl (23W), ADA bathroom, (always on) 1x ccfl (23W), sudo bathroom, (always on) 2x6x F96T12 (900W) in sudoroom & CCL (on at night when open) 1x ccfl (23W), stage overhead light to see by (was on) 5x23W ccfl + 5x75W bulb (490W) stage real lights (were off) 1x ccfl (19W), stageside room (was on) 108W fan and 23W ccfl (131W) room above stageside (both on) bulb xmas lights (20W), above stageside (on, good for safety) sudoroom & CCL servers and internet equipment - 150W perhaps? john&mary ??? i turned off the lights in the basement "law library" room, there was no one there. I turned off the fan and light in the above stageside room. That saved us 531 watts, or $66.08 per month (always on versus never on) all the remaining stuff that was on and I didn't turn off adds up to: 1275 + 14 + 150 + 46 + 287 + 50 + 23 + 23 + 900 + 23 + 19 + 20 + 150 = 2980 watts, which if left on 24/7 would be 2181.36 KW-H or $370.83 per month. That is based on a rate of 17 cents per kilowatt-hour. PG&E charges rates based on Tiers: http://www.pge.com/en/myhome/saveenergymoney/plans/tiers/index.page It looks like if we use more than the average amount of electricity (based on the chart they show on that page) our average energy rate might be closer to 25 cents per kilowatt-hour bringing the above count to $545.34 we don't know what John and Mary are using upstairs, and we haven't added in any other uses of power (such as ventilation fans) so i don't know why our bill was $900 last month. Maybe the 1800W chandeliers were on a lot? Maybe i'm wrong about the chandelier bulbs being 25W and they're 40W each? Most likely, i'm guessing our energy usage is so far above "average" that we are mostly in Tier 4, putting our electric rate closer to 32 cents per KW-H. If that's the case, we should consider switching to Time Of Use: http://www.pge.com/en/myhome/saveenergymoney/plans/tou/index.page Either way, we should save energy by turning off the fucking lights when we're not using them. -jake

PG&E and questions about power (electrical!).

by niki

Hey y'all. You may or may not be aware but since we have moved in, our monthly PG&E bill has gone from $481 to close to $900. I'm guessing it's just going to continue to climb. I realize that we're using a lot more electricity than when John and Mary were living there but I want us to please be mindful of the expense!! Does anyone have thoughts as to what could be contributing to such an increase? Is it simply having more lights on, more often? Also - please turn off lights when you are not using them. I often see lights left on around the building and it would be great if we could all get in the habit on turning lights off when we leave a room! xo N

Media Alliance event on Oct 19 in the basement? Need point person

by Danny Spitzberg

Hey all, the Omni ballroom working group got a request for a 6–8pm meeting by the Media Alliance on Sunday, Oct 19. That's the same evening as the Naomi Klein event, but because they are merely meeting to talk and maybe watch a short video with an estimated 35-50 people in attendance, I think they might be able to fit in the basement comfortably. Here's everything submitted: Timestamp: 9/20/2014 22:40:59 Contact: Tracy Rosenberg, Media Alliance tracy(a)media-alliance.org 510-684-6853 Name of Event: Bay Area Civil Liberties Coalition Open Meeting Description: BACLC is a coalition of organizations and individuals that works on local and regional responses to mass blanket surveillance by government and law enforcement. This is an open meeting to launch projects and we will screen a 30 minute documentary film. Estimated attendance: 35-50 Start/end time: 10/19/2014 18:00:00–10/19/2014 20:00:00 Public event, free, currently not sponsored by an Omni member group I sent Tracy a very brief email saying "We're reviewing this request and will respond to you this week." Might Sudo be open to sponsoring this event? If so, can someone volunteer to liaise with Tracy to make it happen... noting the ballroom is unavailable, so most likely, in the basement? thanks, warmly, Danny

Re: [sudo-discuss] [omnilogistics] Community Print Studio - Two Announcements

by David Keenan

Here are my thoughts, TIL always said it wanted a printing resource center for the community. It was pitched consistently as a cross between the IPRC in portland and Occucopy, that would provide affordable print and art-making tools to the community - essentially a service bureau on steroids, for everyone, which sounded awesome. I realize this printing collective is still in a state of becoming, but $100/pp/mo is e.g. a lot more than the $55/pp/year the IPRC charges, and seems like a pretty high bar to any kind of community involvement. One worry I have about this project in its current state is, from the description it sounds like six(?) independent, unnamed 'presses' (businesses?) like TIL who it seems banded together to have a place to print their own stuff, and perhaps less so really to provide resources to the larger community. That's not necessarily a bad thing in itself, but I would like some clarity on this point, since I have no idea who these other 5 businesses besides TIL even are, or how big these businesses are, how many people are involved with them, etc. And then I have a hard time understanding how offering one day a week of being open for actual community use and the rest for private business use, enough to qualify the project as fundamentally community-oriented. I had also hoped accompanying the amazing machines, that there would be a companion area of more pedestrian equipment like a couple pre-press workstations, tabloid printers, letter laser printers and copy machines could be made available to those who simply need to make flyers for social justice events etc quickly and cheaply that would maybe, not cost them $100/mo? You know, kind of like Occucopy provided.. But maybe that's coming - I'm not saying they're not moving fast enough. I just wonder where the space and planning *is* for those machines, that will probably get a lot more use from the community at large than a C&P? It seems like that's not part of the plan anymores.. is that true? Basically there are several still-unanswered aspects about the structure and application of this print collective that have little to do with how awesome printing machines are, how awesome the idea is, how awesome the people involved are, and everything to do with simply being fair to *other* collectives, with respect to distribution of space, rent and expenses that all of the collectives in the building must negotiate. IE this application must be looked at in context of what other collectives are paying and how they are using shared space too, not just on the merits of the printing collective alone and what it offers in isolation. I also think there is a lot of pressure built into this proposal, possibly unintended but still there, to agree to everything it says and STFU, because this brand-new collective has already moved all their machines down there prior to making themselves known, so it doesn't feel like the Omni collective has much room to have a say about it. It is certainly not the normal procedure of like, actually deciding on whether a group should move in and what they should contribute BEFORE they move in. Not after, as if its just some kind of formality.. If any of these 5 other businesses that have collectivized together to use their machines in the basement are incorporated, they may have to have individual legal agreements (leases of some sort) with OOC directly. I'm not sure actually, but I suspect that may be in order for OOC decisions made at meetings to trump innate tenant rights laws, and in order that insurance liability be binding, etc. With respect to TIL subletting its upstairs office that was mentioned at the meeting, that could totally break our collective structure and is not OK in my view. Subletting is so ripe with problems that undermine collectivity I can't even begin to count them all. Rather the expectation should be, if TIL needs less space in that office, then they can rent a desk or 2 in there from the OOC, and those other individuals / businesses they share that office with will be their full equals in there, also as tenants, with the same rights and responsibilities, subject to the same acceptance process and legally binding agreements as every other tenant in the OOC. In the OOC, there is equality amongst tenants, that seems fundamental to me. New tenants, groups or businesses in the OOC should be a group decision, not one person's or a single group's. Right? Also with respect to TIL curating shared spaces in the omni, i would say, please, be sure to let everyone in the omni co-curate all the shared spaces with you, if that is cool. Friendly amendments: I propose this proposal be split into two proposals - one with regards to TIL and its rent reduction, including its desire to sublet its upstairs office one with regards to the print collective & its space, rent, structure, etc. I see no reason why one proposal should depend on the other. Questions: 0. Would the collective be willing to turn on the machines and use them during the Thursday delegates meeting so we can hear how loud (or not) they are? 1. What are the intended operating hours of this collective? 2. What is the collective structure of this group. How are decisions made? 3. Does this group have open membership - can anyone join and use all the machines, provided they are adequately trained? 4. Aside from TIL, what are the names of the six other presses/businesses that appear to largely comprise this group, and who is involved in them? 5. What business or person legally owns which machines in the basement? 6. Is this collective intended to be run as a business (be it a nonprofit or for-profit), or is this a collective that seeks to make access to their machines as affordable and available as possible to our community? IE, if your membership grows and gross revenue rises: - will your member dues go down from $100/pp/mo? - or will you simply buy more machines and continue to expand into the basement? - will someone profit? If so, who? - Do you have any thoughts about paying more rent to Omni if your membership increases? Going with the sliding-scale rental formula of the omni, based on affordability and ability to pay. 6. Given you can only afford $600 and you apparently have over ten members paying $100/ea, how did you come up with the $600 figure? 7. It was mentioned at the meeting that running a print studio was 'incredibly expensive'. Given that the print collective will not be paying more in utilities than say BAPS, who has, increasingly worryingly, no dedicated space (and no huge power-slurping machines), I am wondering what these incredible expenses are. Are you putting consumables like paper and ink that will get made into things that will be presumably sold, in the same category as e.g. power or water as an operating expense, when consumables might also be called the raw materials for a commodity? Are you counting the purchase of the machines, or the one-time moving costs of the machines into the basement, as an ongoing expense? What are these ongoing, super high expenses, ie how much exactly do they cost? What's the actual budget? 8. Would the collective and its component participating businesses be willing to disclose financial statements on a regular basis to assess rent affordability? 9. Excepting TIL & Laura D., who from the printing collective has done any work on the Omni, or participates in any working groups or work on the omni, aside from organizing and moving their own printing gear? (I do realize that was a hell of a lot of work, but I'd like to know, since generally I never see any of em in the building nor the machines used.) 10. Does the printing collective know how much rent we are collecting, vs what we will owe in total, come Oct 1? IE does the collective have any sense at all of the Omni's total financial responsibility? 11. If the machines are too loud for a class to take place simultaneously, does the collective intend to ask BAPS and other collectives not to use the basement during their work time? 12. Does it seem a fair distribution of the rent burden that for example a collective we just met last week who has done no work on the Omni, receive 1/3 of the basement for a little more than half the rent BAPS pays, who comparatively has no dedicated space? Is it fair that Rise Above, with more expenses per person, pay $1000 for less space? 13. Does the printing collective believe in a financial model in which member rosters soar and more people use the omni, but rental income stays exactly the same, in a period in which we are not actually making rent? Sorry if I come off as a hardass about this but I am mostly repeating things I heard all week David On Sun, Sep 21, 2014 at 9:15 PM, yar <yardenack(a)gmail.com> wrote: > On Sun, Sep 21, 2014 at 8:52 PM, ▽ ∞ ✳︎ > <forever(a)timelessinfinitelight.com> wrote: > > *We will bring forth a revised Community Print Studio proposal to Omni > > soon, which we would like to make a decision on during the October 2nd > > delegate meeting*.

Biohackers Discuss: Ebola! this evening at 7pm.

by Patrik D'haeseleer

Does the Ebola epidemic in Africa have you freaked out yet? Ebola is all over the press with pictures reminiscent of a true pandemic. We've been following the news and have been sifting out facts from fears. Join us this evening at 7pm in CCL, and we'll help you separate the hype from the science, and the fearmongering from the human tragedy. Bring your questions as we talk about how scientists and epidemiologists examine outbreaks. We will show you how you can help with the relief effort in the countries hit by Ebola - and maybe even in studying the virus! *Biohackers Discuss: Ebola! <http://www.meetup.com/Counter-Culture-Labs/events/207834272/>* Patrik

Re: [sudo-discuss] robot hacking - help crack the code!

by Jake

last night I plugged a second serial port into the 3d printing computer and connected it to the robot's floppy drive - and then wrote a program to man-in-the-middle the conversation between the two. read 123.JBI from disk: http://spaz.org/~jake/robot/read123.log delete 123.JBI: http://spaz.org/~jake/robot/delete123.log save 124.JBI: (a copy of 123.JBI) http://spaz.org/~jake/robot/save124.log read 124.JBI from disk: http://spaz.org/~jake/robot/read124.log if you do a diff of read123.log and read124.log you will see the slight differences in the packets. Note that the file creation times are different, not just the filenames, in packets mentioning that info. the most succinct examples are these: disk: \x02\x13\x00LST0001123.JBI \x00\xfc disk: \x02\x13\x00LST0001124.JBI \xff\xfb yasnac: \x02\x0f\x00FRD123.JBI \xdc\xfc yasnac: \x02\x0f\x00FRD124.JBI \xdb\xfc the escape codes (starting with \x) are two-character hexadecimal codes for unprintable characters. This is how python does it, which means you can copy these strings directly into python, for example, to test a theory on how they are checksummed. Like this: print sum([ord(c) for c in '\x02\x13\x00LST0001123.JBI \x00\xfc']) that will give you the 8-bit checksum, but that's not what it's using. perhaps it's a 16-bit checksum? if we figure this out, we can write programs for the robot with our own computers and upload them to it, by pretending that we are its disk drive. i looked through this doc but did not find the info we need at this point: http://spaz.org/~jake/robot/479236-17-Communications.pdf poc||gtfo: https://github.com/jerkey/yasnac/blob/master/src/mitm.py -jake
