01:26 < genehacker> this is a video of richard stallman dancing
01:36 < fenn> thanks for the warning
01:57 < ybit> um, i'll have to read the logs, but i gave a good spill on diyh+ and skdb at the meeting today
01:58 < ybit> wouldn't be surprised if 4-6 people joined diyh+,diybio,om mailing lists and maybe came in here?..since strages mentioned that he met me on this channel and people were curious about it
01:59 < ybit> the u.s. pirate party offered to help me restore my house and build the hackerspace :P
02:00 < ybit> also mentioned to nykodemus there that it occured to me that most hackerspaces aren't going to be drop 4-5k on photolith machine
02:00 < fenn> is diyh+ worth reading?
02:02 < ybit> as say the hacker consortium has ~23 members that pay a monthly fee of $40 and if they save enough to build one of these projects, it would be hard convincing the others that they can buy parts for a machine that might work as opposed to purchasing stuff which you know will work
02:02 < ybit> sure, there's a few interesting items on there
02:03 < fenn> just finished "misspent youth".. crikey the book turns into a british version of Stranger in a Strange Land by the end
02:04 < ybit> nykodemus: btw, i'm not sure who does the video (oh shit i was taped o.O), but please inform him if you will to keep it under my handle 'ybit' and not my real name, that could potentially be embarassing as i wasn't planning on giving a speech in the first place until i realized nobody was signed up to speak, so i figured what the hay 
02:04 < fenn> why potentially embarrassing?
02:05 < ybit> because i was completely unpreprared and made it more of a discussion instead of a speech 
02:05 < fenn> sfw
02:05 < ybit> there's cursing, aside from that it's sfw
02:06 < fenn> meh
02:06 < ybit> a lot of things i couldn't recall and with a group of people staring at me, uh, it was uh, different
02:06 < fenn> yep
02:07 < fenn> practice makes perfect
02:07 < ybit> and i immediately realized afterward why speakers are always asking for feedback afterwards, it's because you want to know wtf everyone is thinking, did you make an ass of yourself just now, etc.
02:08 < ybit> nykodemus also brought up a good point, at most hackerspaces there's not many bio peeps
02:08 < fenn> i'm sort of curious how the whole security community plays into it
02:08 < ybit> so much of what i said may have been chinese to them, but it was presented and relevant sites were talked about so they can get more info
02:08 < ybit> fenn: go on/
02:09 < ybit> nashville's hacker consortium was there
02:09 < fenn> to me it doesn't seem like there's much related material between cracking servers and fooling around with cnc machines
02:09 < ybit> they are the guys who put on phreakNIC
02:09 < ybit> very cool guys
02:11 < ybit> swabbie_strages: you changed your name, same thing i told nykodemus, er, please put the video under my handle whoever guy it was that recorded that stuff 
02:11 < ybit> inform him please
02:12 < fenn> don't worry mate we'll get your laminated communist party member card sent right over pronto
02:13 < fenn> then you'll have a perfectly reasonable explanation for the feds
02:16 < ybit> the usb authentification door has been improved
02:16 < ybit> it was pretty neat
02:16 < ybit> the atl group has a kickass rfid sys in place
02:16 < fenn> what does it do?
02:17 < fenn> gee this doesnt sound too good for british authors: "As of the publication of his tenth novel in 2004, his works had sold over two million copies worldwide, making him Britain's biggest-selling science fiction author"
02:17 < fenn> pretty sure i'd never even heard of peter hamilton before a few weeks ago
02:17 < ybit> fenn: for authentification/door unlocking
02:18 < ybit> they have personal greeting for each person that comes through the door
02:18 < fenn> spooky :)
02:22 < fenn> "Commonwealth Saga explores the social effects of the almost complete elimination of the experience of death following widespread use of the rejuvenation technique described in Misspent Youth."
02:22 < fenn> so those interested in this sort of thing would probably be better off reading that instead
02:23  * fenn wonders if he used enough pronouns and vagueries
02:25 < fenn> oh poo it's a new book.. i thought he had come up with all this internet stuff through extrapolation
02:25 < ybit> damn those fried oreos for being so tasty
02:26 < fenn> don't worry, you're not the only one with a candy habit
02:27 < ybit> hehe, the phreaknic guys were talking about looking up corporate parties at restaurants and crashing the event, how to do it, etc :P
02:28 < fenn> simple, wear a suit, have business cards, be cool
02:28 < ybit> ..for free food
02:28 < ybit> nope, jeans and t-shirts is what they wear :)
02:29 < fenn> at restaurants maybe.. but that's not where the good food is?
02:29 < ybit> swabbie_strages, nykodemus, did either of you write down the name of the sites they mentioned, mine's in my car i do believe and i'm too sleepy to get up from this chair, if i get up, i'm falling down on the bed behind me 
02:30 < ybit> they were showing some really swank restaurants
02:31 < fenn> i wonder if i should sit down and learn javascript for real
02:32 < fenn> it certainly seems like it's not going away
02:39 < ybit> java's not going away, why not you learn that as well :P
02:40 < ybit> anywho, sleep -> welding -> fix library paths/finish installing pythonOCC
02:47 < ybit> before that happens, question for ya: fenn, why do you need javascript? (now i'm gone)

03:15 < fenn> i also want to learn chinese; it don't mean i agree with the whole fascist thing they've got going on

08:48 < ybit> 03:16 < fenn> there's not really any subsitute for javascript unfortunately
08:48 < ybit> s/unfortunately/fortunately
08:48 < kanzure> back in 2001 i tried out vbscript. seemed to suck.
08:49 < kanzure> it was a way of embedding microsoft's macro language (which was sort of like visual basic) into web pages
08:50 < ybit> hi kanzure 
08:50 < kanzure> hello ybit
08:50 < ybit> fenn: you never answered my question, why might you need javascript?
08:51 < kanzure> ybit: maybe he was looking at http://heybryan.org/projects/uncertainfuture/index3.svg
08:51 < ybit> that uses js?
08:51 < kanzure> yep. js+svg.
08:52 < ybit> so why that might influence him to learn js?
08:52 < kanzure> we've been talking a lot about using distributions in skdb
08:52 < ybit> it can be done in any other language, i don't see the use of learning js atm
08:52 < ybit> distros of?
08:52 < ybit> skdb similar to debian?
08:52 < kanzure> especially for expressing a likelihood of failure when certain magnitudes of certain units are present at an interface
08:53 < kanzure> no, probability distributions
08:53 < kanzure> fuck
08:53 < kanzure> anyway, yes, i agree that it would be ineffective to do this in js 
08:53 < ybit> but that graphy can be d..right
08:53 < kanzure> but pyjamas outputs js and other windowing systems
08:54 < kanzure> so the same app you write for your gui toolkit can be displayed through a web interface
08:54 < kanzure> so presumably he'd want to know the nitty gritty javascript bullshit?
08:54 < kanzure> dunno
08:54 < kanzure> just a guess
08:54 < kanzure> i was asleep
08:57 < ybit> http://mail.python.org/pipermail/python-list/2005-June/328509.html --could have swore i saw something more promising at one time
08:57 < ybit> Talking to XPCOM in Python
08:57 < ybit> "The techniques for using XPCOM in Python have been borrowed from
08:57 < ybit> JavaScript - thus, the model described here should be quite familiar to
08:57 < ybit> existing JavaScript XPCOM programmers."
08:57 < ybit> http://public.activestate.com/pyxpcom/tutorial.html
08:57 < ybit> So in theory you should be able to create a python script interpreter,
08:57 < ybit> at least for Mozilla. In practice you'd either need to be an expert
08:57 < ybit> with the Mozilla source code, XPCOM, and Python... or you'd find
08:57 < ybit> yourself becoming an expert by necessity.
08:57 < kanzure> pyjs converts python code to javascript 
08:57 < kanzure> for instance, lists in python are converted to a new class in javascript
08:57 < kanzure> so that you can have the "append" method for a list, for instance
08:58 < kanzure> literally it spits out some classes and methods to pyjs.js or something
08:58 < kanzure> you upload that to your server for inclusion
08:58 < ybit> similar to swig, aye? so why not just use py?
08:58 < kanzure> what?
08:58 < kanzure> i don't know if swig does javascript
08:58 < kanzure> would be surprised
08:59 < ybit> it's the reverse of swig actually
08:59 < ybit> er, not really
08:59 < ybit> similar, there :)
08:59 < kanzure> what pyjs does is look at the python classes while they are in memory and just traverses through them and spits out pre-formatted javascript
08:59 < ybit> since it's more of a horizontal translation
08:59 < kanzure> at least that's my understanding. didn't sound like it was anything more complicated.
09:01 < kanzure> hm i can't seem to find "computational recipes" in my inbox
09:01 < kanzure> wasn't there a thread called "recipe representation" on om once?
09:01 < kanzure> http://web.archive.org/web/20070112225127/http://www.anthus.com/Recipes/CompCook.html
09:07 < ybit> a lot of hits from grep on 'manufacturing recipes'
09:07 < ybit> or just 'recipe' by itself
09:08 < ybit> published in 1985 called Computational Recipes where a fellow named
09:08 < ybit> "plain text cooking recipes" into computer readable interchange format
09:08 < ybit> 'cooked' with more computationally literate recipes. I want both form
09:09 < ybit> so i'm guessing yes there exist a thread on this :)
09:10 < kanzure> got it
09:10 < kanzure> that link is what i wanted btw
09:11 < kanzure> still not sure i understand his notation
09:14 < kanzure> for instance: *shallot, 10 g /add =reduce
09:17 < kanzure> ah in the email i said it was "posix" notation, but he said "postfix" in the book
09:24 < ybit> swabbie_strages: what'd you say in the two hands doc interview?
09:24 < ybit> or what were they asking
09:46 < kanzure> http://adl.serveftp.org/~bryan/computerized-cooking-recipes.zip 59 recipes in the RxOL format.
09:48 < katsmeow-afk> computerized ?
09:48 < kanzure> that's the name of the book
09:49 < kanzure> http://adl.serveftp.org/~bryan/computerized-cooking-recipes/lamb-and-lentil-stew.rxol
09:49 < ybit> http://www.health.state.ny.us/environmental/indoors/air/guidance.htm
09:50  * ybit is looking at the doc above and wondering what you actually use to measure air quality
09:50 < katsmeow-afk> same as outdoor, i guess
09:50 < ybit> which is?
09:51 < katsmeow-afk> assorted sensors like hot methane sensors, vacs with dust catchers, etc

09:52 < ybit> where might ya get this equipment?
09:52 < katsmeow-afk> i asked ADEM how they measured particulate pollution, he said a vac cleaner with a micropaper filter on it, they weigh the filter, run the vac for 24 hrs, weight it again
09:53 < katsmeow-afk> the determine the size with a microscope
09:53 < katsmeow-afk> radon is detected with a geiger counter, naturally
09:53  * ybit is airing out the shack since it's had flammable gases in it for a good while
09:54 < ybit> ..so welding can be done in there..
09:55 < katsmeow-afk> err, it's not a flammable building?
09:55 < ybit> anyway, it would be nice to live and am nervous to enter in there 
09:56 < ybit> katsmeow-afk: it's made of wood if that's what you're asking..
09:56  * katsmeow-afk nods
09:56 < ybit> btw, i see you survived the storms from the other day, congrats
09:56 < katsmeow-afk> got 3 inches in 24 hrs the 19th
09:56 < katsmeow-afk> Leeds, downthe interstate, got severe flooding, one storm parked there for 6.5 hrs and pounded them
09:57 < ybit> that would be great if you had a bin or two which were recycling that water
09:57  * katsmeow-afk logged the event with radar images every 30 minutes
09:57 < katsmeow-afk> yeas, i know :-(
09:58 < katsmeow-afk> the radar images were worse than hurricanes that have gone over
09:58 < katsmeow-afk> few bad winds tho, mostly lotsa rain
10:00  * katsmeow-afk makes some breakfast to eat while watching Stephanopolous
10:02 < kanzure> while searching around for endy's email address,
10:02 < kanzure> http://brokenscience.com/2008/06/12/drew-endy-hasnt-done-shit/
10:02 < ybit> someone mentioned someone rewriting the tcp/ip stack used in their network so if hackers did break into the sys, they wouldn't be able to send anything :P
10:03 < katsmeow-afk> use a C64 :-)
10:03 < katsmeow-afk> actually, you can use an avr, if the desktop box prebuilds the packets
10:04 < katsmeow-afk> i did a sorta stack in mirc, using mirc's "raw" sockets 
10:05 < katsmeow-afk> windows did send mirc the packets inthe right order, but when doing several internet transations at once, the packets incoming to mirc were out of order
10:06 < katsmeow-afk> interleaved
10:06 < katsmeow-afk> so i had to sort and build the page from the incoming, as if it were a stack, sorta
10:09  * ybit wishes we had an invasion of bioPOETS in diyh+ instead of actual poets :)
10:14 < kanzure> huh erik winfree offered me a job?
10:14 < kanzure> why didn't i take that?
10:21 < ybit> because you became interested in skdb
10:24 < kanzure> no it's actually relevant to skdb
10:25 < kanzure> i mean, dna compilers and so on
10:37 < ybit> sure, but it also isn't aspects of it either
10:51 < jonathan__> I found plastic bits in my quinoa for breakfast.   what is the food industry coming to
10:51 < ybit> quinoa, yum
10:52 < ybit> jonathan__: stop being secretive and share with me your plans :-)
10:52 < jonathan__> plastic bits, not so yum
10:53 < jonathan__> got it from whole foods as well
10:53 < ybit> yeah, that comes as a shock

15:24 < kanzure> apparently "units" is a commutative ring

15:47 < kanzure> hell yes
15:47 < kanzure> what is food energy density? :(
15:48 < kanzure> doesn't that depend on how good your body is at processing the food?
15:48 < fenn> no
15:49 < fenn> its the oxidative energy content of the food divided by its mass

17:11 < ybit> bkero, fenn, katsmeow-afk: what's the purpose of setting the polarity on the dc welding?
17:14 < fenn> one side burns hotter because of electron evaporation
17:15 < ybit> is it easy to tell which one burns hotter?
17:15 < ybit> why would i want it to not burn hotter, for certain metals that have __ property?
17:15  * ybit should join a machine shop channel 
17:16 < fenn> hah
17:16 < ybit> okay, off to do some pretty terrible welding i'm sure
17:16 < fenn> i'd tell you the answer, but http://xkcd.com/567/ screwed me up
17:26 < genehacker> DON'T WELD GALVANIZED STEEL

17:29 < fenn> that's old news
17:30 < kanzure> is it?
17:30 < fenn> i thought it was finished like 2 years ago
17:30 < kanzure> in ".dwg" format
17:31 < kanzure> the "big one" is finished
17:31 < kanzure> but there's a mini-one that he is working on apparently
17:31 < kanzure> but obviously i don't care about the mini one at the moment
17:31 < kanzure> .window 12
17:31 < kanzure> fuck you
17:32 < kanzure> apparently he didn't upload them because he doesn't have enough web space for the 50MB archive. maybe tomorrow he'll upload them to adl.
17:33 < fenn> 50MB of .dwg's?
17:33 < kanzure> yes
17:33 < fenn> that's ridiculous
17:33 < kanzure> have you seen this yet? http://lcamtuf.coredump.cx/guerrilla_cnc1.html

17:34 < fenn> no
17:38 < kanzure> "evil finder is a cool hack that employs numerology to conclusively prove the evilness of a given subject"
17:38 < kanzure> ok this sounds familiar
17:38 < kanzure> oh it was also mentioned on makezine.com before. 
17:38 < kanzure> still worth reading though.
17:45 < kanzure> ok he says he can export to IGES and STEP
17:57 < kanzure> fenn, ybit: he's uploading the dwg files to adl:/home/achiestdragon/ (not done yet. looks like it might take two hours.) just fyi.. guess i'll play around with converting them.

18:15 < kanzure> are there any /good/ ascii art generators?
18:15 < fenn> no.
18:15 < kanzure> are you an ascii art generator?
18:15 < fenn> ascii art is terrible by definition
18:15  * kanzure tries to increase fenn's character resolution but forgot the control code :(
18:17 < kanzure> all these asciiart tools like to think that asciiart means "convert pixels to individual colored text" instead of "come up with some actual ascii art"
18:18 < fenn> yep
18:18 < kanzure> a shitty GA can do better than this
18:18 < fenn> i'd much rather have a line art to stroked svg converter
18:18 < kanzure> svg2ascii seemed obvious to me but apparently that doesn't actually exist
18:19 < fenn> but xml is already ascii :)

18:32 < kanzure> hm svgfig claims it should be used for making graphs, but isn't that kind of lame without gnuplot conversion support?

20:07 < ybit> DC Negative = more heat into workpiece, deeper penetration. Standard setting for steel
20:07 < ybit> DC Positive = more heat into electrode, less penetration, best left for thin metal.
20:07 < ybit> AC, best for non-ferrous metals, like aluminum, because the back and forth flow provides cleaning action.
20:08 < ybit> not sure why you wouldn't want the cleaning action for the other metals though
