| 00:26 | | * Vornicus hunts around Fairchild Semiconductor for a particular toy. |
| 00:27 | < Vornicus> | found it. "quad 2-input multiplexer" |
| 00:27 | < Vornicus> | 74257. |
| 00:29 | <@McMartin> | That doesn't soudn like a particularly exciting toy on its own. What are you building? |
| 00:30 | <@ToxicFrog> | As in, it's a set of four 2->1 muxes on a single chip? |
| 00:30 | < Vornicus> | Well, I'm trying to figure out how to build a divider; I need one of those. |
| 00:30 | < Vornicus> | TF: exactly. |
| 00:30 | < Vornicus> | With only one control line. |
| 00:33 | <@ToxicFrog> | Aah. |
| 00:34 | | * Vornicus emails his professor because he found it. |
| 00:39 | | * Vornicus sends. |
| 00:45 | < Vornicus> | And for some reason I always thought multiplexers were the other way around |
| 00:46 | <@ToxicFrog> | Nope, that's demultiplexers. |
| 00:46 | < Vornicus> | Yeah. |
| 00:46 | <@McMartin> | A mux is unary to binary, right? |
| 00:47 | <@ToxicFrog> | A mux is any number of lines >1 to 1. |
| 00:47 | <@ToxicFrog> | A demux is 1 line to >1 lines. |
| 00:47 | <@McMartin> | Er, how does that work for digital circuits if the >1 isn't 2? |
| 00:48 | <@ToxicFrog> | Typically it's a power of 2. |
| 00:48 | <@McMartin> | Right but |
| 00:49 | <@ToxicFrog> | You can easily construct it from 2->1 muxes, which in turn can be built from individual logic gates. |
| 00:49 | <@McMartin> | Unless the output line is actually a bus... |
| 00:49 | <@McMartin> | RIght, but when so built you get a bunch of outputs. log_2 of them |
| 00:49 | <@ToxicFrog> | No |
| 00:49 | <@ToxicFrog> | You get 1 output |
| 00:49 | <@McMartin> | OK, perhaps I've forgotten what multiplexers actually do. |
| 00:49 | <@ToxicFrog> | You have n inputs, log2(n) control lines, and 1 outut |
| 00:50 | <@ToxicFrog> | One of the inputs is connected to the output, and the control lines select which one |
| 00:50 | <@McMartin> | A demux you feed it one input, the nth output goes high. |
| 00:50 | <@McMartin> | Aha. |
| 00:50 | <@McMartin> | Yeah, OK, I'd forgotten the control line aspect. |
| 00:50 | < Vornicus> | So a band mux: n*m inputs, log2(n) controls, and m outputs. |
| 00:50 | <@ToxicFrog> | Yeah. |
| 00:50 | <@McMartin> | Yeah, at that point it all falls into place. |
| 00:51 | <@McMartin> | Wow. It has been 11 years since digital design class. |
| 04:19 | < Shoukanjuu> | So, the reason it wanted authentication to access the applications folder was because the root account was active. |
| 04:19 | < Shoukanjuu> | I fixed it. \o/ |
| 04:44 | < Vornicus> | Gah. Fuck a duck. |
| 04:44 | | * Vornicus needs to write a load/save widget. |
| 04:48 | < Vornicus> | Which means, among other things, figuring out fonts. |
| 04:51 | < Shoukanjuu> | Got my TV tuner today, but it's not getting S-video |
| 04:52 | < Shoukanjuu> | "no signal" |
| 04:52 | < Shoukanjuu> | Thoguh I'm perfectly fine with the audio, the video doesn't work O: |

| 09:32 | <@McMartin> | Also \o/ |
| 09:32 | < Shoukanjuu> | :D |
| 09:33 | | * McMartin *really* needs to break a bunch of this out into a McMUtil package or class or whatnot. |
| 09:33 | < Shoukanjuu> | I like how the main character in Radiant Dawn's first part can't gain speed to save her life. |
| 09:33 | <@McMartin> | FE? |
| 09:33 | < Shoukanjuu> | Oh, hold on, defense either. *NO points in defense all the way, 19 levels* |
| 09:33 | < Shoukanjuu> | Yeah |
| 09:34 | < Shoukanjuu> | It doesn't help that this game is harder in Easy Modw than Thracia 776 was |

| 09:35 | <@McMartin> | Now the raw .jar file will actually have a proper status bar icon. |
| 09:35 | < Shoukanjuu> | Sexy. Also: 94% miss. NOT so sexy |
| 09:35 | <@McMartin> | Honestly, I can't even call this "bending Swing to my will" |
| 09:35 | <@McMartin> | This is more "me being arsed to actually look at the class's method list" |
