12:16 < nsh> kanzure
12:17 < kanzure> no!
12:17 < kanzure> er, hi
12:17 < nsh> i've been thinking about abstracting a generalised dependency framework
12:17 < nsh> which could then be applied to whatever
12:17 < kanzure> there's some code in skdb for that if you want
12:17 < nsh> e.g. skdb, software dependencies, and my own intended applications: understanding dependencies
12:17 < kanzure> hm or there used to be
12:18 < nsh> mm
12:18 < kanzure> how do i search for a deleted file in git?
12:18 < nsh> no idea
12:18 < nsh> 1. Use git log --diff-filter=D --summary to get all the commits which have deleted files and the files deleted;
12:18 < nsh> Use git revert $commit to revert that particular commit.
12:18 < kanzure> aha
12:18 < kanzure> http://adl.serveftp.org/skdb/core/dep.py
12:18 < kanzure> there's not much there
12:19 < nsh> good starting point though
12:19 < nsh> thanks
12:19 < nsh> the idea is to create a framework for codification of the dependency structures of various fields of knowledge
12:19 < kanzure> what is a dependency structure?
12:19 < nsh> to formalise teaching order 
12:20 < nsh> well, say you can't learn about integration by partial fractions until you have learnt about partial fractions
12:20 < kanzure> doesn't CKAN do this?
12:20 < nsh> one sec
12:20 < kanzure> or at least they claim to
12:23 < nsh> sorry, phone rang
12:23 < nsh> i'll check out CKAN
12:25 < nsh> Why Not Just Use the Creative Commons Search Facility in Google/Yahoo/etc
12:25 < nsh> Two main reasons:
12:25 < nsh> 1. ...
12:25 < nsh> 2. The registry is designed to support holding much more metadata than simply whether the work is open on not. In particular we want to be able to support automated installation of knowledge packages in the future (which requires things like dependency and version information).
12:25 < nsh> that perilous phrase: "in future"
12:26 < nsh> there are some papers in IEEE on knowledge dependencies though
12:26 < nsh> i should read the literature
12:27 < nsh> http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4274669
12:28 < nsh> hmm, seems a little skew to my purposes

14:58 < kanzure> i wonder how much time i spend registering on mailing lists versus actually writing code for these stoopud projects
15:01 < kanzure> fenn: marcin would like some example electronics packages in skdb sooner-rather-than-later
15:06 < fenn> anything in particular?
15:07 < fenn> i was thinking the reprap stepper motor drivers
15:07 < kanzure> oh i was thinking of just some simple data sheets for starters
15:07 < fenn> easier to quantify their capabilities than, say, an arduino
15:07 < kanzure> but yes
15:07 < fenn> data sheet doesn't mean anything
15:07 < fenn> cp *.pdf project/
15:07 < fenn> sfw
15:07 < kanzure> for resistors, capacitors, inductors, transformers, basic electronics components
15:07 < kanzure> no not a .pdf
15:07 < kanzure> blah
15:08 < fenn> i dont understand; what would i say about a resistor?
15:08 < kanzure> resistance?
15:08 < fenn> -__
15:08 < kanzure> stroke face?
15:08 < fenn> ^ that's my eye melting off
15:09 < kanzure> fenn: doc/installing line 96ish
15:09 < kanzure> any hints for writing a sed for that
15:09 < fenn> "Everyone who pledges $32 or more will get an exclusive, gold-tone anodized piece of the first production run of Maker Beam."  wow I can add it to my T-slot collection! narf
15:10 < kanzure> sed -e '148s/^/blah../' src/wrapper/environment.py or something
15:10 < kanzure> er maybe i'm just lazy, let me go figure it out
15:10 < fenn> line numbers wont work
15:10 < kanzure> why not
15:10 < fenn> they always change
15:10 < kanzure> no this is the .tar.gz
15:10 < kanzure> for pythonocc-0.3
15:10 < fenn> hm
15:11 < kanzure> bad?
15:11 < kanzure> oh it's SWIG_OPTS
15:11 < fenn> ok i guess
15:11 < kanzure> it starts like this: SWIG_OPTS = ['-python','-modern','-fcompact','-c++',
15:11 < kanzure> and continues for a few lines
15:11 < kanzure> with random ^M's thrown around in there
15:12 < kanzure> i guess i can replace the "= [" 
15:12 < fenn> this should work: sed -i 's|/usr/local/inc|/usr/include/opencascade|' wrapper/environment.py
15:12 < kanzure> there's no pretty way to do this as far as i can tell
15:12 < fenn> is that what you were asking about?
15:12 < kanzure> nope
15:12 < kanzure> there's a particular line that i need to edit
15:12 < kanzure> it's the SWIG_OPTS list on line 144 in pythonOCC-0.3/pythonOCC/src/wrapper/environment.py
15:13 < kanzure> forget it.. i have it solved. just sucks
15:13 < kanzure> does -i edit it in place?
15:13 < kanzure> becase sed (stuff here) original_file.py > original_file.py totally blanks it out
15:14 < fenn> yeah -i means in place
15:15 < kanzure> what about -e?
15:15 < kanzure> hm -e is just an expression

15:33 < kanzure> hello superkuh, welcome back
15:34  * fenn consults linux standards base...
15:35 < ybit> this guy responded to a thread on facebook i sent out awhile back offering a place to stay: http://www.facebook.com/shawntyler
15:35 < kanzure> i asked in #debian and they just rolled their eyes about yet-another-extra-package-manager :)
15:35 < ybit> he lives 15 mins away from where the event is taking place and is going himself
15:35 < kanzure> ybit: neat
15:35 < fenn> tell them to call me when apt can handle volts and man-hours
15:35 < fenn> er, dpkg
15:36 < superkuh> Hello. My cable modem has been losing it's upstream every few hours. I imagine it will continue.
15:37 < fenn> sheesh.. way to hide the data linux foundation
15:39 < fenn> ok fuck these guys
15:41 < kanzure> ybit: how goes the .debs
15:41 < fenn> ah debian worked great on the other hand
15:42 < fenn> http://www.debian.org/doc/debian-policy/ch-opersys.html#s-fhs   points to http://www.debian.org/doc/packaging-manuals/fhs/fhs-2.3.html
15:43 < kanzure> hm. /opt is hardly used as far as i can tell
15:43 < kanzure> #debian suggested /usr/local/
15:43 < fenn> yeah nobody uses /opt
15:43 < kanzure> i don't see /var mentioned
15:44 < kanzure> hm /usr/local/ isn't mentioned either, but /usr/local/share is
15:44 < kanzure> ah /var is in section 5
15:44 < kanzure> "/var contains variable data files. This includes spool directories and files, administrative and logging data, and transient and temporary files."
15:44 < fenn> /usr/local/share/skdb/packages then?
15:45 < kanzure> "The /usr/local hierarchy is for use by the system administrator when installing software locally. It needs to be safe from being overwritten when the system software is updated. It may be used for programs and data that are shareable amongst a group of hosts, but not found in /usr."
15:45 < fenn> s/packages//
15:45 < fenn> we can put the main stuff in /skdb/skdb
15:46 < kanzure> ew
15:46 < fenn> or in /usr/share as a deb package
15:46 < kanzure> yeah
15:46 < fenn> ok but people need to compile it too
15:47 < kanzure> what is /usr/local/share/man/ in particular?
15:47 < fenn> man pages for compiled programs
15:47 < kanzure> hm leocad is in my /usr/local/share/
15:47 < kanzure> but why would the man pages be there rather than somewhere else
15:47 < fenn> why would they be elsewhere?
15:47 < kanzure> in /usr/local/share/ i have applications, bmp, desktop-directories, doc, emacs, fonts, hibernate, icons, leocad, locale, man, mime, octave, perl, ppd, sgml, swig, texmf, xml
15:48 < kanzure> just seems kinda arbitrary
15:48 < fenn> it's like a mirror of /usr/share
15:48 < kanzure> ah there we go
15:48 < fenn> for local (non-.deb) stuff
15:48 < kanzure> yes /usr/share/ is much more interesting
15:48 < kanzure> ok. makes sense to me
15:49 < kanzure> //usr/local/share/skdb/ it is.
15:49 < fenn> you didn't know where 99% of the data on your system was?
15:49 < kanzure> no :(
15:49 < kanzure> god i suck
15:49 < kanzure> i don't go looking for these packages half the time.
15:51 < fenn> hey i'm riding to rauchwerk's place in ten minutes or so, you're welcome to come along
15:51 < kanzure> will he take you back?
15:51 < fenn> probably not
15:51 < kanzure> are you taking your bike?
15:51 < fenn> yup
15:51 < kanzure> guess i should come
15:51 < fenn> i might be there a long time

17:52 < QuantumG> to: merkle@merkle.com
17:52 < QuantumG> subject: recent work
17:52 < QuantumG> Over the last 10 years I read many of your papers with interest, including "A Minimal Toolset for Positional Diamond Mechanosynthesis" this year.. just thought I'd ask if I may: What are you working on now?
17:53 < kanzure> :)
17:53 < kanzure> probably nanoengineer-1
17:53 < kanzure> or whatever the nanocad package is called
17:53 < genehacker> why nanoengineer?
17:54 < QuantumG> be nice if he got back to the business of figuring out how to turn chemical simulations into working hardware
17:54 < genehacker> do you have a way to bootstrap nanotech from synthetic DNA you make in your kitchen?
17:54 < QuantumG> kthxbye
17:55 < QuantumG> http://www.molecularassembler.com/Nanofactory/2003Proposal.htm
17:55 < QuantumG> The deliverables from this work will be:
17:55 < QuantumG>  1. The specifications for a set of molecular tools which, taken collectively, will be able to synthesize a wide range of stiff hydrocarbons.
17:55 < QuantumG> 2. The description of a set of molecular machine components made from stiff hydrocarbons that can be synthesized by the use of the aforesaid tools (including details of the synthetic sequence).
17:55 < QuantumG> presumably he's working on step 2
17:56 < genehacker> sounds like it replicates sounds like fun
17:57 < QuantumG> the whole "design ahead" strategy is so faith based
17:58 < genehacker> what do you mean design ahead?
17:58 < genehacker> relying on computational chemistry instead of real chemistry?
17:58 < genehacker> yeah that is faith based
17:58 < QuantumG> they're designing a machine and the parts for that machine, without any idea of how to bootstrap to get those parts
17:58 < genehacker> oh
17:58 < QuantumG> and assuming that the bootstrap will enable them to create those parts
17:59 < QuantumG> suppose the bootstrap only allows you to create much less capable parts
17:59 < QuantumG> well then you need another bootstrap

18:51 < fenn> can't they build the first tool tips with AFM probes?
18:51 < genehacker> it's harder than it looks
18:52 < fenn> of course, but is it possible?
18:52 < genehacker> tooltips expire after a while due to the minute amount of stuff in the 'vacuum'
18:52 < fenn> will it disintegrate after a second?
18:53 < fenn> should be easy enough to extend that time indefinitely with 'getters'
18:53 < genehacker> I forget the exact figure but I think it's between 14 minutes and a day
18:56 < genehacker> oh 1000 seconds
18:57 < genehacker> http://www.molecularassembler.com/Papers/PathDiamMolMfg.htm
18:57  * fenn giggles at the thought of someone actually using kiloseconds
18:57 < genehacker> 16.7 minutes
18:57  * ybit tickles CIA-33 
18:57 < QuantumG> ya, figuring out how to make the toolset using AFMs and such is other great "practical" work that I wish they'd get on with
18:58 < QuantumG> cause at some point they'll gunna have some great design that just needs that bootstrap.. and then the bootstrap will never happen :)
18:58 < ybit> if they don't get to it, i'm sure someone in here will when we finally get around to building our afm
18:59 < fenn> but *actually* doing it is so boring
18:59 < genehacker> it's more than AFM work
18:59 < genehacker> of course the link I posted is about doing diamonoid nanosynthesis
19:00 < fenn> is it not the same thing?
19:00 < QuantumG> Freitas Jr. and Merkle are collaborators.
19:01 < genehacker> QuantumG is talking about hydrocarbon synthesis
19:01 < QuantumG> http://www.molecularassembler.com/Papers/MinToolset.pdf
19:01 < QuantumG> nah, that's the same thing
19:01 < genehacker> ok
19:02 < genehacker> does he have some new method for making the tools?
19:02 < QuantumG> far as I know, they have no idea how to make the tools
19:02 < QuantumG> thus the whole "simulate it all and figure out the bootstrap later" 
19:03 < fenn> i dont get it; why can't you just dip an afm probe in a vat of tooltip molecules?

19:03 < ybit> off-topic: i've been busy this entire weekend with family. if a message from me says "you all are a bunch of nerds", ignore it, it's probably my uncle or some crazy person in the family. i say that because i walked in here today having left the irc window open and someone had typed that. of course, i think the screen was viewing ##electronics, but anywho.. 
19:03 < fenn> bah they're simple organic molecules any chemist could make
19:04 < genehacker> here's the problem
19:04 < QuantumG> they're all active
19:04 < genehacker> they're poisoned easily
19:04 < genehacker> and need to work in a super clean high vacuum

19:22 < xp_prg> genehacker do you know how I can make bio-paper which is a type of hydro gel and bio-ink which are cells put in cell suspension that allow the cells and cell suspension to be printed with an inkjet printer using a piezo printer head?
19:24 < genehacker> no but I speculate that the internet might
19:24 < xp_prg> I have googled for 3 hours trying to find it
19:25 < genehacker> http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6TWB-4CGM8MB-1&_user=108429&_rdoc=1&_fmt=&_orig=search&_sort=d&_docanchor=&view=c&_searchStrId=1114483318&_rerunOrigin=google&_acct=C000059713&_version=1&_urlVersion=0&_userid=108429&md5=58c3b3a9580d72d333c46a6c2db67972

19:26 < genehacker> The two hydrogel-based substrates were prepared as the print substrates (or bio-papers). One of the bio-papers used was soy agar gel, and the other was a collagen gel. Both were coated on glass coverslips (22×22 mm2). The soy agar gel was made from Trypticase® soy agar solution (Becton Dickinson & Co., Cockeysville, MD) by dissolving 1.5 g of powdered soy agar in 50 ml of nanopure water. After autoclaving for 15 min, 50
19:27 < genehacker> good luck
19:30  * fenn suggests using a potato

20:11 < kanzure> yes
20:12 < fenn> hmm i just get 'the file or folder heybryan.org does not exist'
20:12 < kanzure> does anyone else (someone who is not lame) get this same error
20:12 < fenn> works if i add a / though
20:13 < fenn> :(
20:13 < kanzure> why would it say heybryan.org doesn't exist?
20:13 < fenn> i dont know.. obviously something is going wrong
20:13 < fenn> i notice other browsers automatically add a / to the end
20:14 < fenn> also i dont get any branches on the list of branches
20:14 < kanzure> works for me in wget

20:15 < kanzure> oh 
20:15 < kanzure> well you're supposed to use your imagination

20:16 < kanzure> it gives you a page yes?
20:17 < genehacker> hey jason do you know how I can get winblows 7 for free from the school?
20:17 < kanzure> for someone who hates windows you sure use it a lot
20:18 < genehacker> yeah that's the reason why I hate it
20:18 < genehacker> because I can't not use it
20:18 < kanzure> bullshit
20:19 < genehacker> my horrendously DRM
20:19 < fenn> i bet you havent even looked for ways around it
20:19 < ybit> genehacker: try saying that in ##linux, but before you do that, let me grab some popcorn
20:19 < genehacker> 'd fluids text book does not work on not windows
20:19 < genehacker> I have some popcorn right here
20:20 < ybit> genehacker: you could try virtualizing windows within your distro
20:20 < genehacker> is that like dualbooting?
20:20 < genehacker> or running windows on a virtual machine?
20:20 < ybit> the latter
20:21 < genehacker> I assume this is different from wine?
20:21 < kanzure> yes
20:22 < genehacker> also my laptop has a longer battery life on windows
20:23 < genehacker> hmmmm.... maybe there are drivers for linux for my computer
20:26 < genehacker> or perhaps windows isn't telling the truth
20:44 < xp_prg> wouldn't you say that agar agar is too viscous to be use in an inkjet printer?
20:47 < genehacker> it might be
20:47 < genehacker> I'd suggest running the numbers first
20:48 < kanzure> fenn: happy now? http://heybryan.org:8081/package/lego/:branches
20:48 < kanzure> shit the links don't work
20:49 < timschmidt> genehacker: many Linux distributions don't install / enable CPU speed throttling by default.  That alone could account for slightly worse battery life.  Also, check out powertop.  It details exactly what your computer is doing in order of most power consumption, in real time.
20:50 < kanzure> let me guess: X11
20:50 < genehacker> also is there some sort of python or other library for monitoring how much time my battery has left?
20:50 < kanzure> linux keeps extensive data on your battery discharge history
20:51 < kanzure> so you can definitely access the data if you want to
20:51 < kanzure> i forget where it's located
20:51 < xp_prg> genehacker running the numbers?
20:51 < genehacker> I want to trigger/turn off functions based on battery life
20:52 < genehacker> that I have at a moment
20:52 < timschmidt> sys/bus/acpi/drivers/battery/PNP0C0A:00/power_supply/BAT0
20:52 < timschmidt> for me
20:53 < kanzure> me too
20:53 < timschmidt> aren't we special
20:53 < kanzure> it says "12520000" in voltage_now
20:53 < kanzure> hrm
20:53 < kanzure> charge_now = 4320000
20:54 < timschmidt> 12440000 for me
20:54 < timschmidt> charge_now = 5200000
20:54 < kanzure> genehacker: so yeah, it's easy to get a python script to access those files
20:55 < genehacker> so now I have to figure out how to estimate battery life from those...
20:56 < kanzure> ubuntu comes with a program called "power statistics"
20:56 < kanzure> gives you lots of fancy graphs
20:56 < timschmidt> it's easy.  There are files that tell you what the full values are.
20:56 < kanzure> discharge time profile, for instance
20:59 < genehacker> thanks for the info
20:59 < genehacker> also composites are awesome

21:05 < fenn> i can make a composite peanut butter and jelly sandwich

21:08 < genehacker2> bimetallic sheet and coextruded plastic aren't composites
21:08 < QuantumG> eating a sandwich is certainly mechanically easier than eating peanut butter out of the jar
21:08 < fenn> that's debatable
21:09 < genehacker2> hmmm....
21:09 < kanzure> if you win the debate will you make me a sandwich?
21:09 < genehacker2> I guess that might be a composite

21:09 < kanzure> counter claim: not a jar
21:09 < fenn> not to be used as sun protection
21:09 < genehacker2> the toughness of a peanut butter and jelly sandwich is higher than the toughness of peanut butter and jelly alone
21:10 < fenn> this guy didnt get the message http://barfblog.foodsafety.ksu.edu/uploads/image/PeanutButter_baby.jpg
21:11 < genehacker2> I don't think peanut butter and jelly sandwiches have any engineering applications...
