00:03 < drazak_> kanzure: it's http://heybryan.org/books/ right?
00:07  * ybit has been afk for 13 mins
00:07 < ybit> MEAs in general, -"in-vivo"
00:07 < drazak_> ugh, it's not working
00:07 < ybit> anything that's available
00:08 < ybit> i'm considering just purchasing the MEAs until i can make them myself
00:09 < drazak_> does anyone have a link to the bryan books?
00:09 < ybit> i have a copy of the repo
00:09 < drazak_> can you look for a book for me?
00:09 < ybit> which one?
00:09 < drazak_> Thermodynamics: An Engineering Approach sixth edition
00:09 < drazak_> and the cd
00:09 < drazak_> I dunno if he'd have had the cd
00:12 < ybit> http://www.google.com/search?hl=en&client=firefox&rls=org.mozilla%3Aen-US%3Aunofficial&hs=kMa&q=%22thermodynamics+an+engineering+approach%22+sixth+edition+%28pdf%7Ctorrent%7Cebook%7Crar%7Czip%29&aq=f&oq=&aqi=
00:12 < ybit> that may be quicker for you
00:12 < drazak_> I'm just proving that it can be found
00:12 < ybit> in particular: http://www.ebookee.com.cn/Solutions-manual-to-Thermodynamics-An-Engineering-Approach-6th-Ed-by-Cengel_249377.html
00:13 < ybit> oh
00:13 < drazak_> someone was complaining that they spent 200 bucks on it
00:13 < ybit> meh, i can't locate atm
00:13 < drazak_> and I was like
00:13 < drazak_> "uh, I'm fairly sure I can get it pretty easy... infact I might have it right here!"

06:48 < Ond> Hi nsh.
06:49 < Ond> So, this is some transhumanist channel correct?
06:49 < Ond> I think I remember h plus being a magazine of some sort.
06:49 < Ond> And a simple google search has substantiated that thought. So...
06:52 < Ond> What lively people.
06:55 < nsh> i think it's short for humanity-plus
06:55 < Utopiah> hi Ond , everybody is working on their secret labs in their volcana islands
06:55 < nsh> mostly we plan how to take over the world
06:56 < Ond> Haha.
06:57 < Ond> You transhumanists.
07:00 < Utopiah> btw I don't think http://www.hplusmagazine.com/ is affiliated to this channel, the topic still has to be set manually, no funding for it
07:02 < Ond> Harsh.
07:02 < Ond> Shouldn't Obama be on that?
07:03 < Utopiah> picking a transhumanism Czar amongst members of this channel? good suggestion

08:12 < kanzure> hplusmagazine isn't affiliated with this channel
08:12 < kanzure> hplusmagazine isn't even affiliated with WTA
08:16 < kanzure> George Dvorsky and James Clement are spending a fortune on publishing hplusmagazine for some reason, even though something like that should be able to be done for zero dollars
08:16 < kanzure> I don't know why all these people think that things on the internet need to cost so much money
08:20 < Utopiah> because a lot of people prefer to raise fund and lost themselves in easy administrative tasks rather than *actually doing* it?
08:21 < kanzure> i prefer to assume that they are idiots
08:21 < Utopiah> not necesseraly exclusive ;)

09:16 < ybit> hmm
09:21 < kanzure> what?
09:22 < ybit> my internet is down but i can use other ports for communicating and i find that peculiar
09:25 < kanzure> that happened back at the dorm I was living in for a while
09:26 < kanzure> so the server was able to send on port 80, but I couldn't use links, elinks, lynx, etc.
09:26 < kanzure> which was quite odd
09:26 < kanzure> (the server was on a separate line)
09:29 < ybit> definitely going to invest in laser printer and experiment with the laminated transparent sheets j. cline was mentioning on the mailing list a few days ago. think that's the quickest, most precise way of getting into microfluidics 
09:30  * ybit doesn't trust myself scribbling lines on CDs
09:30 < ybit> s/myself/himself
09:48 < kanzure> oh fenn was right. pygraph.graph.cut_edges() returns the same thing as my find-all-cutsets code. boo.
09:48 < kanzure> well, not quite
10:01 < ybit> how many are working on skdb?

10:33 < kanzure> Take advantage of supernodes, which create constraint equations. For circuits containing independent voltage sources, a supernode is generally used when two nodes of interest are separated by a voltage source instead of a resistor or current source. Since the current (i) is unknown through the voltage source, this extra constraint equation is needed.
10:36 < kanzure> http://adl.serveftp.org/dokuwiki/nodal_analysis#take_advantage_of_supernodes
10:36 < kanzure> that's supposedly why cutsets are important
10:37 < kanzure> now I need to convert that to through-and-across-leetspeak
10:40 < kanzure> why is current unknown through a voltage source?
11:03 < kanzure> "There is no way of knowing the current through a voltage source in advance." really?
11:32 < kanzure> " The current flowing out of one supernode must sum to zero. Thus, the current in branches of a cut set must sum to zero. "
11:50 < kanzure> http://adl.serveftp.org/dokuwiki/nodal_analysis#supernodes
11:50 < kanzure> why does nobody in ##electronics know about this?

14:26 < kanzure> http://adl.serveftp.org/dokuwiki/nodal_analysis#terminology_of_cutset_equations
14:29 < kanzure> I don't know why you don't just go to every node and apply KCL
14:29 < kanzure> why would you bother throwing cutsets into it?
14:33 < kanzure> oh
14:33 < kanzure> in one case there's a node that has two edges going out, but only one coming in
14:33 < kanzure> (in terms of current flow direction)
14:33 < kanzure> this is the one that is never in a cutset in the Twung & Khaueroeq example
14:33 < kanzure> er, Tung & Kwan

16:41 < kanzure> well I guess that makes sense
16:41 < kanzure> 2 * 5 = 10.
16:41 < kanzure> but sympy.diff(5*b*physics.units.m,x) == 5*m**2

22:04 < genehacker> do you know if there is anyway to test if my cable modem is broken or that my cable is out?
22:04 < genehacker> my internet is down
22:07 < kanzure> if your router assigns you an address via dhcp, chances are that it's still working
22:08 < kanzure> however, wireless routers have been known to, uh, suck
22:09 < genehacker> well here's the problem
22:09 < genehacker> the cable is plugged into to my cable modem
22:09 < genehacker> but the cable modem can't see the cable
22:09 < kanzure> check if dhcp is working
22:10 < genehacker> how do I do that?
22:10 < genehacker> trying to remember the default IP address for routers
22:11 < kanzure> I don't use windows.. so I can't help you there.
22:11 < genehacker> what is the default IP address?
22:11 < kanzure> 192.168.1.1
22:11 < kanzure> 192.168.1.100 something
22:11 < genehacker> ah yes that
22:11 < genehacker>  thanks
22:11 < kanzure> also try ping 192.168.1.*
22:11 < kanzure> ping -b 192.168.1

22:17 < ybit> genehacker: ifconfig typically
22:19 < ybit> and something like dhcpcd ethX or dhclient ethX should help

23:01 < kanzure> facial recognition library I mean
23:01 < kanzure> although I suppose you could be bothering to try to do other things than facial recognition
23:06 < ybit> suppose a few chdk enabled cameras like the a490 would do the job
23:06 < ybit> or even something like the Trendnet TV-IP312W + zoneminder
23:10 < ybit> nodal analysis, aye...
23:12 < ybit> can't decide if i'm going to be a hen, duck, cat, or dog while you guys are constructing skdb
