Dear Kopimists and the People who Love Them.
For the featured Filo delicacy for Friday Filosophy, we will have potato burekas.
I propose we talk about the difference between source code, object code, and executable code in regards to 1st Amendment protection. In other words, when is code speech and when is it a speech-act subject to less legal protection?
Below is an excerpt from an essay by Lee Tien, a brilliant EFF attorney for more than a decade, on Software as Speech (2000). These two paragraphs are in the section: Viruses and other "dangerous" software.
Of course, as always, we can talk about whatever else. Such as conscience and the unconscionable, perhaps.
Lee Tien, Publishing Software as a Speech Act, Vol. 15 Berkeley Tech. Law Journal (2000)
http://www.law.berkeley.edu/journals/btlj/articles/vol15/tien/tien.html
> Let’s return to the virus hypothetical.192 The main concern lies in the fact that the software may be “diverted” toward unlawful purposes, regardless of the speaker’s intent. This concern is, however, not unique to software. It also applies to other types of information usable for mischief or harassment, whether highly technical like information about nuclear weapons, or utterly mundane like a person’s name, address or telephone number.
> Even if the virus author merely posts the source code and fails to release it in active form, the issue remains whether the posting was done with an intent to communicate. If the author claims that she intended it to communicate, we would need to examine the context to decide the plausibility of that claim. There will often be a plausible claim. There is no question that people study viruses and other dangerous software in order to prevent or relieve harm.193 One way to control a virus is to publish its source code so that systems operators can disable or protect against it. Communicating a virus’ source code as part of such an effort qualifies as a speech act because the publisher intends to communicate how the virus works in a conventional way. In fact, one could imagine entire journals or Internet sites devoted to viruses and other dangerous software.194 When such publications aim to alert the world to these dangers, their intent is clearly communicative.

I'm confused actually. why where there pins on the raspi being used at all?
the serial connection is usb, what else needs to go to the MSP430, power?

hi everyone,
during yesterday's meting we discussed doing film screenings on fridays.
how would people feel about april 19th being the first day?
i've started a wiki entry where you can add suggestions for movies:
https://sudoroom.org/wiki/page/Fabulous_Friday_Films
- marina
Is complete - ish. I'd love some sudoroom stickers /other recommended
decoration. On a practical level, the whole transparency thing is difficult
to see against a white wall. Maybe I'll create some kind of LED solution
above it.

Hi All-
Here's the 4/2013 Statement for The Sudo Room. Utilities were the lowest
I've ever seen them this month. Congrats!
Thank you!

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.

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

I've already got the "calculating the daytime paths" part. I have python code using pyephem that given a latitude, longitude, and time, gives back the altitude and azimuth of the sun. For a fixed platform, that you can align once, that should be all you need. 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. For radio astronomy, it would add noise to the system which you would need to figure out how to filter out somehow.

+1 on using a geared DC motor with encoder. we will basically wind up with a custom servo. i have some IR sensors that i got with the intention of making a photo interrupt type encoder - just need to print some dartboard-esqe patterns on transparency sheet and center it on the shaft or a coupler. steve i am very interested in building a sun-tracking mount for solar panels and those servos we have at sudo room would work for that application...i think there are also a few boxes that have geared stepper motors too, from the same batch of parts which i think was an overflow from AMT. two main options fro pointing as i see it are calculating the daytime paths geometrically, or using closed loop control to dither the panels around the sun like the thermopile on a sidewinder missile. also would be interested in one where the yaw axis of the panels is actuated by virtue of being mounted on a rover chassis (roomba???) with 2-axis magnetometer as feedback on pointing.
