| drazak_ | kanzure: it's http://heybryan.org/books/ right? | 00:03 |
|---|---|---|
| * 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 | 00:07 |
| ybit | i'm considering just purchasing the MEAs until i can make them myself | 00:08 |
| 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 | 00:09 |
| 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 | 00:12 |
| 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!" | 00:13 |

| Ond | You transhumanists. | 06:57 |

| kanzure | hplusmagazine isn't affiliated with this channel | 08:12 |
| kanzure | hplusmagazine isn't even affiliated with WTA | 08:12 |
| 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 | 08:16 |
| Utopiah | because a lot of people prefer to raise fund and lost themselves in easy administrative tasks rather than *actually doing* it? | 08:20 |
| kanzure | i prefer to assume that they are idiots | 08:21 |
| Utopiah | not necesseraly exclusive ;) | 08:21 |
| ybit | test | 09:16 |
| ybit | hmm | 09:16 |
| kanzure | what? | 09:21 |
| ybit | my internet is down but i can use other ports for communicating and i find that peculiar | 09:22 |
| kanzure | that happened back at the dorm I was living in for a while | 09:25 |
| 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) | 09:26 |
| 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 | 09:29 |

| ybit | s/myself/himself | 09:30 |
| kanzure | oh fenn was right. pygraph.graph.cut_edges() returns the same thing as my find-all-cutsets code. boo. | 09:48 |

| 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. | 10:33 |
| kanzure | http://adl.serveftp.org/dokuwiki/nodal_analysis#take_advantage_of_supernodes | 10:36 |
| kanzure | that's supposedly why cutsets are important | 10:36 |
| kanzure | now I need to convert that to through-and-across-leetspeak | 10:37 |
| kanzure | why is current unknown through a voltage source? | 10:40 |
| kanzure | "There is no way of knowing the current through a voltage source in advance." really? | 11:03 |
| 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. " | 11:32 |
| kanzure | http://adl.serveftp.org/dokuwiki/nodal_analysis#supernodes | 11:50 |
| kanzure | why does nobody in ##electronics know about this? | 11:50 |

| kanzure | http://adl.serveftp.org/dokuwiki/nodal_analysis#terminology_of_cutset_equations | 14:26 |
| 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? | 14:29 |
| 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 |

| genehacker | my internet is down | 22:04 |
| kanzure | if your router assigns you an address via dhcp, chances are that it's still working | 22:07 |
| kanzure | however, wireless routers have been known to, uh, suck | 22:08 |
| 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 | 22:09 |
