| ybit | 13:25 < kanzure> mike mentioned that he would like to package the neural tissue scanner into skdb | 00:35 |
|---|---|---|
| ybit | mike? | 00:35 |
| ybit | 13:25 < kanzure> he doesn't even know if it's a university-only project, or if todd has the reigns on it or what | 00:36 |
| ybit | todd? | 00:36 |
| ybit | must be utexas people | 00:36 |
| ybit | 7:53 < timschmidt> excitingly, my wrench-buildable machine got two fully working axes, including motor mounts, lead screws, everything last night. Still only a wrench and a hacksaw were used. | 00:42 |
| * ybit is impressed | 00:42 | |
| timschmidt | :) | 00:43 |
| QuantumG | http://www.youtube.com/watch?v=2cjWTWrma9Q | 00:43 |
| timschmidt | I _didn't_ do most of the work | 00:43 |
| timschmidt | I'll have pictures up as soon as I get some from the other members in attendance. | 00:44 |
| ybit | timschmidt: how much do you guess the wrench-buildable machine will cost in total? | 00:46 |
| timschmidt | depends heavily on what price you can get the square perforated tube for. I estimate $75 in parts other than the tube, motors, and electronics. I paid $22 / 6ft for the tube, and used perhaps 20ft of it. | 00:49 |
| timschmidt | meh. more like 30ft of it | 00:50 |
| ybit | this make me very happy and greedy | 00:51 |
| timschmidt | the next highest cost items are the drawer rails, for which I paid $14 / pair | 00:51 |
| timschmidt | and used 3 pair | 00:51 |
| timschmidt | everything else is pocket change | 00:51 |
| ybit | just plan on me bothering you for awhile after i save up some money :) | 00:52 |
| timschmidt | each pillow block bearing (of which there are 6) costs about $0.50 to build. Lead screws are inexpensive allthread. Couplers (for motors + lead screws) are two $0.60 shaft collars (which I also use to restrict the lead screws) JB-welded together. | 00:53 |
| timschmidt | And that's about all of it | 00:53 |
| timschmidt | nuts, bolts, washers, a spacer or two, and some pipe hangers to couple the stages to the drive nuts. | 00:54 |
| timschmidt | I think the square perf tube is both the most expensive and hardest to find component. Any help finding a cheap source of it is welcome. | 00:56 |
| timschmidt | I bought mine at Menards | 00:56 |

| QuantumG | and they intend to win the first prize of the second level this year :) | 01:00 |
| katsmeow-afk | cheap bearing holders: http://designerthinking.com/idlers.html | 01:02 |
| genehacker_light | oh yeah | 01:02 |
| katsmeow-afk | i don't sell them, but i made some, that's a howto | 01:02 |
| katsmeow-afk | standard bearings, stock steel tubing, make as long or short as you like, no real tools needed | 01:03 |
| ybit | kanzure, so skdb has been renamed to tangible bit?... | 01:04 |
| katsmeow-afk | the tubing is heavy enough to weld or braze into othe bits of steel or wood | 01:04 |
| * ybit likes skdb | 01:04 | |
| ybit | much shorter | 01:04 |
| ybit | ..and precise.. as i've stated before | 01:04 |

| katsmeow | re skate bearings, englich bearing of near-same size, but true english (1/4 inch bore) measures are a lil cheaper than real skate bearings | 01:09 |
| ybit | first time i saw this: http://openfarmtech.org/index.php?title=Open_Source_Lathe | 01:13 |

| katsmeow | gnite ybit | 01:14 |
| genehacker_light | good night | 01:28 |
| genehacker_light | I will not sleep tonight | 01:29 |
| katsmeow | ybit, just a note, remember this: re: http://openfarmtech.org/index.php?title=File:Clamps.jpg that style clamp is terribly inaccurate for the ID, in fact you can place one side ont he rod, and *rock it* side to side, as in over .010 play on each side; those things are not bored properly | 01:34 |
| katsmeow | however, with a drill press, you can make more accurate ones | 01:34 |
| katsmeow | they get real pricey in stainless and larger sizes, but you can get them in any shaft size | 01:35 |

| kanzure | I merged. | 04:45 |
| Smari | any luck yesterday? | 04:45 |
| kanzure | pull? | 04:45 |
| Smari | from which? | 04:46 |

| Smari | kanzure, it's my new computer. | 04:48 |
| Smari | My computing devices are named after mathematicians - my cellphone is Shannon, the work laptop Cauchy, my old desktop is Julia, my old laptop was Carroll... I've also had Hausdorff, Euler, Mandelbrot and a couple of others. | 04:49 |
| Smari | The chronology of the archive is very strange. | 04:50 |
| kanzure | your commits should be in the logs | 04:50 |
| Smari | they are | 04:50 |
| Smari | but they're in the wrong order. I'm not complaining though, it looks cool. | 04:51 |
| kanzure | wrong order? how did that happen? | 04:51 |
| kanzure | isn't it by date? | 04:51 |
| Smari | Nope | 04:51 |
| kanzure | what should it be by? | 04:52 |
| Smari | Some things from 2009-07-26 come before 2009-07-18 in the chronology.. | 04:52 |
| Smari | It's ordered by in which order the changes were made to the archive.. | 04:52 |
| Smari | so you probably merged folders in some order.. | 04:52 |
| kanzure | I think you might be using a special option to "git log" | 04:53 |
| Smari | which didn't agree with how they came into existence (and how could it?) | 04:53 |
| Smari | I'm using gitk | 04:53 |
| kanzure | aha | 04:53 |
| Smari | but hey, it seems to work | 04:53 |
| Smari | Hm. | 04:54 |
| Smari | Something's missing. | 04:55 |
| kanzure | 'media' | 04:55 |
| kanzure | I was hesitant to import binary data. | 04:55 |
| Smari | sources is also missing | 04:55 |
| kanzure | check out inventory/ | 04:55 |
| Smari | Ah | 04:56 |
| Smari | I see no real reason not to import binary data, as long as it's static stuff. | 04:56 |
| Smari | media isn't just binary either | 04:57 |
| Smari | a lot of it is javascript code | 04:57 |
| kanzure | there was a few css files and javascript files in there, yeah | 04:57 |
| kanzure | but it would have confused the fuck out of you | 04:57 |
| kanzure | if I had just imported the CSS and js | 04:57 |
| kanzure | and not the images | 04:57 |
| Smari | yeah | 04:57 |
| Smari | It's four images | 04:57 |
| kanzure | no, there were many more | 04:57 |
| Smari | Hmm? | 04:57 |
| * kanzure digs around | 04:58 | |
| Smari | Ah no... | 04:58 |
| Smari | admin/ is a symbolic link | 04:58 |
| kanzure | tangiblebit/tangiblebit.com/media/admin/img/admin | 04:58 |
| kanzure | oh? | 04:58 |
| kanzure | hey, you're right | 04:58 |
| Smari | Its contents shouldn't be imported | 04:58 |
| Smari | Because it's linking to the Django distribution | 04:58 |
| kanzure | ok so four images aren't as terrible as "many" :) | 04:59 |
| Smari | yes. | 04:59 |
| Smari | Should I re-add them or will you merge them in? | 04:59 |
| Smari | Oh, btw.. I don't have | 05:00 |
| Smari | write permissions | 05:00 |
| Smari | on skdb.git | 05:00 |
| kanzure | please go ahead and fix | 05:00 |
| Smari | (do I?) | 05:00 |
| Smari | sure | 05:00 |
| Smari | Actually, there's a bunch of history behind the javascript files... | 05:00 |
| Smari | so could you merge instead? | 05:00 |
| kanzure | yes | 05:00 |
| Smari | thx | 05:00 |
| kanzure | er there's a lot of images in media/javascript/components/slider/img/new/Image101.gif | 05:02 |
| kanzure | er there's a lot of images in media/javascript/components/slider/img/ | 05:02 |
| genehacker2 | still awake or up early? | 05:02 |
| kanzure | neither | 05:03 |
| kanzure | this is the sleep-walking subsystem of kanzure | 05:03 |
| genehacker2 | zombie-mode? | 05:03 |
| kanzure | not quite | 05:04 |
| kanzure | Smari: anything to look for in the logs to see if I was successful? | 05:04 |
| Smari | not... really.. | 05:05 |
| kanzure | "Restructuring javascript interface" ? | 05:05 |
| Smari | kanzure, that would be a good one | 05:06 |
| Smari | yeah | 05:06 |
| kanzure | okay, it worked then. | 05:06 |
| kanzure | now, where should media/ go? | 05:06 |
| kanzure | in inventory/ ? | 05:06 |
| Smari | kanzure, that works, but it has bad side-effects.. | 05:08 |
| Smari | No, actually, I can work around them | 05:08 |
| Smari | It's mostly that Django runs slow if normal files are being passed through it before download. | 05:09 |

| kanzure | does this turn you on? | 05:11 |
| kanzure | muahah | 05:11 |
| kanzure | actually don't answer that | 05:12 |
| Smari | Noooooooooooooo.... how could you?! You evil evil man! | 05:12 |
| Smari | You've converted tabs into spaces | 05:12 |
| Smari | Why don't you just kill me now and have it over with? | 05:13 |
| kanzure | because I enjoy watching developers suffer, or something sadistic like that | 05:13 |
| Smari | Gah, I'm verging on a nervous breakdown here... spaces... spaces for indentation... why oh why... what have I done to deserve this? | 05:14 |
| Smari | :P | 05:14 |
| Smari | I suppose I either have to get over my tab-addiction (which has been with me since 1996) or I convince you that tabs are the right way to go... | 05:18 |
| Smari | and I'm honestly not sure which would be easier ;) | 05:18 |
| kanzure | er right now I'm falling back asleep | 05:18 |
| kanzure | zombie mode over | 05:18 |
| kanzure | er, sleep-walking mode over I mean | 05:18 |
| * kanzure looks around with shifty eyes | 05:18 | |
| Smari | heheh | 05:19 |
| kanzure | Smari: btw, skdb.git is at: /var/www/skdb.git/ on adl | 05:23 |
| Smari | ~/.ssh/authorized_keys isn't working on adl :( | 05:23 |
| kanzure | any suggestions on how to get it working? | 05:23 |
| Smari | no... | 05:23 |
| Smari | sorry | 05:23 |
| Smari | my fault! | 05:24 |
| Smari | That was VERY awkward | 05:24 |
| kanzure | well I'm certainly not interested in using passwords forever | 05:24 |
| kanzure | so getting keys working would be hot | 05:24 |
| Smari | it works | 05:24 |
| kanzure | yay | 05:24 |
| * kanzure sleeps | 05:24 | |
| Smari | just generate your key and put the public key in ~/.ssh/authorized_keys | 05:24 |
| Smari | but make a point of not putting the private key there ;) | 05:25 |

| kanzure | "A strategy for integrating product and process design of aerospace components". Manufacturing Review 3 (3): 178 186, 1990. | 12:23 |
| kanzure | "Simplified generation of all mechanical assembly sequences" <-- bwahah | 12:24 |
| genehacker2 | interesting | 12:26 |
| genehacker2 | you know I've heard that NASA is partially managed by software | 12:26 |
| Inri | What do you mean "managed"? | 12:28 |
| Inri | Obviously they have quite a few algorithms working out logistic matters. :) | 12:29 |
| kanzure | " A compatibility rating between the product profile requirements and the | 12:32 |
| kanzure | alternatives stored in the database for each decision criteria is generated using possibility theory. The vector | 12:32 |
| kanzure | of compatibility ratings are aggregated into a single rating of that alternative’s compatibility. A ranked set of | 12:32 |
| kanzure | compatible material and manufacturing process alternatives is output by the system. | 12:32 |
| kanzure | " | 12:32 |
| kanzure | the preceeding was from 'a decision support system for material and manufacturing process selection' | 12:32 |
| kanzure | "manufacturing process capabilities" doesn't really help you to figure out what breaks and hwen | 12:35 |
| kanzure | *when | 12:36 |
| genehacker2 | shit, you mean everything I just learned in my materials class can now be accomplished by a piece of software? | 12:36 |
| kanzure | "The manufacturing process selection module identifies feasible manufacturing processes and rank them | 12:36 |
| kanzure | according to the compatibility of their capabilities with the product profile requirements. | 12:36 |
| kanzure | " | 12:36 |
| fenn | genehacker2: not even close | 12:36 |
| kanzure | "Figure 6 Possibility of wall thickness under a manufacturing process capability" | 12:37 |
| kanzure | meh that requires the wall to be tagged as such though | 12:37 |
| fenn | CUTDATA provides Cutting Speed and Feedrate recommendations that will result in acceptable tool life, cutting a given material in a specific hardness range or heat treatment condition | 12:37 |
| genehacker2 | ok dang | 12:37 |
| fenn | i wonder how much CUTDATA costs | 12:37 |
| genehacker2 | I wouldn't be surprised though | 12:38 |
| kanzure | "and a compatibility rating vector for each manufacturing process alternative." | 12:38 |
| genehacker2 | there are some formulas for determining the probability of survival for a ceramic material in terms of size and applied stress and defect density | 12:40 |
| kanzure | genehacker2: what we need is a way to say "here are the main ways you fuck up a milling machine" | 12:41 |
| genehacker2 | 1. | 12:41 |
| genehacker2 | stress applied on anypart exceeds yield point | 12:42 |
| genehacker2 | 2. part | 12:42 |
| genehacker2 | is subject to creep and could fail within a certain time period | 12:42 |
| kanzure | Fig. 7. Partial EXPRESS-G diagram of manufacturing resource model for cutting tool data (Jurrens et al., 1996). | 12:43 |
| genehacker2 | 3. stress applied to part exceeds fatigue limit and part will fail within a short time | 12:44 |
| ybit | oh alright, guess i'm gone to scan some books | 12:44 |
| genehacker2 | 4.part happens to be made of brittle material and any bump in the wrong direction could break it | 12:45 |
| kanzure | "2~The use of process specification language for cutting processes" | 12:45 |
| genehacker2 | fatigue would be hard though because fatigue is hard to measure | 12:45 |
| genehacker2 | but those are the generall causes of part failure | 12:46 |
| genehacker2 | oh and corrosion | 12:46 |
| genehacker2 | that too | 12:46 |
| genehacker2 | 5. creep | 12:47 |
| genehacker2 | part slowly deforms until it's useless or breaks | 12:48 |
| genehacker2 | as is happening for the the PTFE barrels on repraps | 12:48 |
| kanzure | "capability profile" | 12:49 |
| fenn | the most often cause of failure is mechanical resonance induced by the endmill cutting forces | 12:49 |
| fenn | that, and crashing... and chip clogging | 12:49 |
| genehacker2 | but if you can figure out stress applied, what sort of vibrations would be produced, and the temperature it operates in you should be good | 12:50 |
| kanzure | SK Gupta keeps on showig up | 12:50 |
| genehacker2 | mechanical res can be figured out | 12:50 |
| fenn | easy for you to say | 12:50 |
| genehacker2 | from computers models | 12:50 |
| fenn | what computer models | 12:50 |
| genehacker2 | that take a really long time | 12:50 |
| fenn | modal analysis? good luck | 12:50 |
| genehacker2 | FEA duh | 12:50 |
| fenn | how do you model an oil film cushion with FEA? | 12:51 |
| fenn | assuming i can even get the parameters describing a machine tool in the first place | 12:51 |
| genehacker2 | parameters describing machine tool might be taken as a function of the head being used, material, being cut, and speed operated at. | 12:53 |
| kanzure | most research seems to have stopped at kerf angles and curvatures and thickness, not considering any other sort of geometrical issues | 12:53 |
| CIA-43 | skdb: * rbbd6086e2c7e /taxonomy.yaml: thread rolling | 12:53 |
| genehacker2 | I'm sure you could figure out some model of vibrations | 12:53 |
| genehacker2 | mechanical resonance causes fatigue related damage? | 12:54 |
| fenn | genehacker2: no i'm talking about the dynamic damping of the machine frame | 12:54 |
| genehacker2 | there are models of it | 12:55 |
| fenn | BRING THEM TO ME! | 12:55 |
| fenn | ahem. sorry | 12:55 |
| genehacker2 | I can't | 12:55 |
| genehacker2 | I've got a test to study for | 12:55 |
| fenn | where can i get some decent minions these days? | 12:55 |
| genehacker2 | just look up dynamic damping | 12:56 |
| genehacker2 | I'll give you the fatigue formula later | 12:56 |
| fenn | whatever. that's not important right now | 12:56 |
| * fenn files it under "simulation" | 12:57 | |
| genehacker2 | it's related to the damage caused by resonance | 12:57 |
| fenn | yes i know | 12:57 |
| genehacker2 | basically you need the max and min stress applied | 12:57 |
| genehacker2 | I can see why it'd be hard though | 12:57 |
| kanzure | what does "process compatibility" even mean? | 12:58 |
| fenn | it doesn't | 12:58 |
| fenn | it's bullshit | 12:58 |
| genehacker2 | and it might get messy and really complicated very fast | 12:58 |
| genehacker2 | because of real parts varying from virtual parts | 12:59 |
| kanzure | think of it more as trying to figure out possible shapes and impossible shapes or possible shapes that can break the system | 13:01 |
| genehacker2 | like hollow spheres inside cubes? | 13:01 |

| kanzure | "wear maps"? | 13:21 |
| kanzure | "The maps have demonstrated that tool wear rates vary with cutting speeds and feed rates used. " | 13:21 |
| kanzure | they don't vary with workpiece geometry/shape? | 13:21 |
| bzsmari | wow, that's insightful! :P | 13:21 |
| bzsmari | I don't think the tool cares what the workpiece is shaped like | 13:22 |
| kanzure | say you mill perpendicular to a surface/plane, | 13:24 |
| kanzure | that will bust your drillbit | 13:24 |
| fenn | breakage != wear | 13:26 |
| bzsmari | you can make certain assumptions about geometry when testing wear rates... | 13:26 |
| kanzure | you don't have to assume.. you have the geometry right in front of you | 13:32 |
| kanzure | bzsmari: maybe fenn should explain | 13:32 |
| * fenn is trying to actually do something | 13:33 | |
| bzsmari | hehe | 13:34 |
| bzsmari | don't worry about it | 13:34 |
| kanzure | fenn: push? | 13:35 |
| kanzure | bzsmari: do you have STEP documentation for Part 522 or Part 224? | 13:40 |
| fenn | i wonder if this is the class i want: Geom2dInt_ExactIntersectionPointOfTheIntPCurvePCurveOfGInter | 13:40 |
| kanzure | yay Thomas Kramer wrote some documentation for ISO 10303/224 | 13:42 |
| bzsmari | kanzure, which is? | 13:42 |
| kanzure | how to do "tagging" of features in STEP files | 13:43 |
| fenn | thomas kramer is my hero | 13:43 |
| fenn | well, sort of | 13:43 |
| fenn | he participated in the mess-making that was EMC1 | 13:44 |
| fenn | Geom2dGcc_Circ2dTan is what i want | 13:44 |
| bzsmari | meh | 13:45 |
| kanzure | "Len Slovensky" is the "owner" of STEP AP 224? | 13:45 |
| fenn | there are step AP's for just about anything imaginable, and they all cost a fortune | 13:45 |
| kanzure | hm it's more about particular things like boss, chamfer, circular_pattern, rather than generic tags | 13:45 |
| fenn | i dont think it's realistic to expect to be able to use any of them | 13:46 |
| kanzure | so if this is not a "feature" then what is it? | 13:46 |
| fenn | says 'machining features' | 13:46 |
| kanzure | then what should I be looking for? | 13:47 |
| fenn | ISO Standard 10303-224 "Application Protocol: Mechanical Product Definition for Process Planning Using Machining Features." | 13:47 |
| kanzure | "how to use random strings that represent features" ? | 13:47 |
| fenn | instead of step files? well, keep in mind we dont have any files with feature information in them in the first place | 13:47 |
| kanzure | no no no | 13:47 |
| kanzure | my task is to figure out how to add a line to a STEP file to "label" something | 13:48 |

| kanzure | ah so the edges are either snaps or inserts, apparently. but that doesn't tell you which snap or which insert mate to use.. | 19:01 |

| kanzure | fenn: do you understand why the unittests don't run | 20:11 |
| kanzure | they don't run because they are in unittests/ | 20:11 |
| fenn | ffs just put test.py back in the main dir and include whatever fucking files you want | 20:11 |
| kanzure | I think you don't understand file system structures for python modules.. | 20:12 |
| fenn | skdb/test.py: import unittests; run_tests() | 20:12 |
| kanzure | why is test.py in skdb/ ? | 20:13 |
| kanzure | try this: http://www.ibm.com/developerworks/aix/library/au-pythontesting2/ | 20:13 |
| Smari | I'm going to go nuts on the directory structure next time I have a moment to sit and focus. | 20:34 |
| fenn | i think it's pretty good right now | 20:35 |
| Smari | I've been actively thinking about the big picture of what we're doing all day. I drew diagrams. Managed to simplify a few things, draw logical connections, figure out a few structural points... most of it is the IIS/supply chain side of things.. | 20:35 |
| Smari | IIS = Industrial Information System | 20:35 |
| Smari | fenn, it's horrible right now. | 20:36 |
| fenn | ok, so my crap is all over skdb/ | 20:36 |
| Smari | fenn, there's no compartmentalization, no logical entry point, no obvious plan.. :) | 20:37 |
| Smari | how do .yaml files, .py files and .dat files belong in the root? | 20:37 |
| fenn | they don't | 20:37 |
| Smari | exactly | 20:37 |
| fenn | i don't like having a big "src" dir | 20:38 |
| fenn | what's the point of that? | 20:38 |
| kanzure | self.assertFalse(skdb.Unit('1') < skdb.Unit('-10')) | 20:38 |
| kanzure | test_negative_cmp | 20:38 |
| Smari | fenn, I'd at least like to separate data from code... and perhaps categorize code into different modules and apps. | 20:39 |
| Smari | What parts are there exactly? | 20:40 |
| kanzure | pymates, your fabmap thing, fablab job scheduling, toolpath swept volumes code, packages, | 20:41 |
| fenn | inventory, simulation, dependency resolution | 20:41 |
| kanzure | simulation? | 20:41 |
| kanzure | fenn and I have different definitions of simulation | 20:41 |
| kanzure | and neither of us are willing to budge :p | 20:42 |
| kanzure | so we keep confusing each other | 20:42 |
| fenn | hm. ok forget "simulation" | 20:42 |
| kanzure | there's something that somewhat approximates SPICES in the repo | 20:42 |
| fenn | whatever you call being able to predict information you don't have about an artifact based on data you do have | 20:42 |

| kanzure | Smari: pull before you commit | 20:44 |
| Smari | yes | 20:44 |
| kanzure | don't be like me :( | 20:44 |
| Smari | Like "fablab job scheduling" becomes "scheduling" | 20:45 |
| kanzure | what? | 20:45 |
| Smari | "toolpath swept volumes code" becomes "toolpaths" | 20:45 |
| kanzure | Smari: I'm not sure you know the project entirely yet | 20:45 |
| fenn | sounds fine to me | 20:45 |
| kanzure | but you might, and I could be very wrong | 20:45 |
| fenn | kanzure always makes excessively verbose names | 20:45 |
| Smari | kanzure, I understand it to a fairly reasonable degree | 20:45 |
| kanzure | okay | 20:45 |
| kanzure | also there's 'pymates' :) | 20:46 |
| Smari | I don't understand everything that's under the hood in your code... | 20:46 |
| Smari | is it okay to call it 'mating' ? | 20:46 |
| kanzure | no, the folder name is 'pymates' | 20:46 |
| Smari | it sounds more kinky... | 20:46 |
| kanzure | but you could just reference the actual folder | 20:46 |
| Smari | I'm talking about moving things and renaming them so that it'll be easy to navigate through the swaths of code... | 20:47 |
| Smari | that will be there :) | 20:47 |
| kanzure | how about you just ask us what you should write? | 20:47 |
| Smari | Uhm | 20:47 |
| kanzure | :p | 20:47 |
| fenn | i didnt realize we had gotten to the point where we need a readme already | 20:47 |
| Smari | Because I'm going to write what I bloody well feel like writing :) | 20:47 |
| kanzure | but you just admitted you don't know what's what | 20:48 |
| fenn | if it's wrong i'll fix it | 20:48 |
| kanzure | okay | 20:48 |
| Smari | *sigh* | 20:48 |
| fenn | keep up the good work smari | 20:48 |
| Smari | fenn, is that a joke? | 20:48 |
| kanzure | .. | 20:48 |
| kanzure | now I'm not sure | 20:48 |
| fenn | yes it was a joke. | 20:49 |
| fenn | wait, now i'm not sure | 20:49 |
| fenn | no offense intended | 20:49 |
| kanzure | which does "no offense intended" evaluate to? joking or not joking? | 20:49 |

| ybit | how do you do it guys? how do you balance social life and me-time/workingArseOff4fun | 21:35 |
| kanzure | what is social life? | 21:35 |
| ybit | ideally, my friends would want to work on the same projects, maybe weld something, make some metal, something fun | 21:35 |
| kanzure | get some better friends | 21:35 |
| ybit | instead it's always getting high or drunk :-\ | 21:35 |

| kanzure | can anyone explain Gundam 00 to me? | 22:12 |
| genehacker2 | are you watching gundam and programming? | 22:12 |
| kanzure | yes | 22:12 |
| genehacker2 | http://sciencelinks.jp/content/view/749/282/ | 22:13 |
| genehacker2 | in order to make a gundam, we'd have to invent some new really lightweight materials | 22:14 |
| genehacker2 | Issue 1: Mass is a major issue as Gundam is slim but would still weigh several hundreds tons if normally manufactured. Its legs are slender: Slender legs are preferable in ensuring control. However, they would result in a lot of pressure being applied to the soles of the feet. Roads and the ground could not withstand the pressure applied from that weight and the body would sink into the ground. | 22:14 |
| genehacker2 | I wonder if carbon nanotube microtrusses would do the trick... | 22:17 |
| fenn | how about ... Gundanium alloy? | 22:20 |
| fenn | and you could power it with a GM particle reactor | 22:21 |
| genehacker2 | a GM particle reactor? | 22:22 |
| genehacker2 | I thought they used minovsky physics or something like that | 22:22 |
| fenn | GM is a special type of minovsky particle | 22:23 |
| genehacker2 | oh ok | 22:23 |
| genehacker2 | how about a plasmak? | 22:23 |
| genehacker2 | it's real | 22:23 |
| fenn | O RLY | 22:23 |
| genehacker2 | it just hasn't been tested for fusion yet | 22:23 |
| genehacker2 | the plasma ball doesn't touch the walls of the containment vessel | 22:24 |
| genehacker2 | the plasma ball is also stable enough to last a couple seconds at room temperature pressure | 22:25 |
| genehacker2 | but in order to do fusion with it | 22:25 |
| genehacker2 | you have to put inside an ULTRA-CANNING machine | 22:25 |
| genehacker2 | IE a device that generates really really high pressure | 22:25 |
| fenn | uh.. i dont think you know what you're talking about | 22:27 |
| genehacker2 | they use devices that generate really high pressures in the food industry | 22:34 |
| genehacker2 | forget it | 22:34 |

| genehacker2 | transformers good? | 22:37 |
| genehacker2 | no they're horrible | 22:38 |
| ybit | perfect | 22:38 |
| genehacker2 | they dissipate quite a bit of energy as heat | 22:38 |
| genehacker2 | my laptop power brick gets hot enough to almost burn me | 22:38 |

| kanzure | fenn: should the unit tests for skdb/dep/ attempt to act like they are supposed to work for the dependency information in skdb/packages/screw/metadata.yaml ? | 23:22 |
| kanzure | at the moment I don't have anything that does anything interesting with the "or" and "and" structure of that dependency outline (although it would be nice if there was something, but I don't know what that something should be at the moment) | 23:23 |
