| 10:12 | <@TheWatcher> | Quote from an email I have just written: |
| 10:13 | <@TheWatcher> | "Where email is concerned, Lovecraft was not simply an author, he was a prophet." |
| 10:16 | <&McMartin> | Is this about the greatest mercy being the inability of the human inbox to correlate all its contents? |
| 10:19 | <@TheWatcher> | I was thinking about the lurking horrors that drift around and through it, especially those parts that have anything to do with HTML emails... |
| 10:21 | | * simon_ has tried for 6 hours to get Win7 on an USB and boot it. |
| 10:42 | < Julius> | simon_: Have you tried Rufus? |
| 11:27 | < simon_> | Julius, I haven't, but once I find someone who uses Windows, I'll try it. |
| 11:28 | < Julius> | Rufus is the only thing I've found for Windows that handles Windows images to USB well. |

| 12:40 | < Julius> | What's the easiest method of sending out email from Java? |
| 12:41 | < Julius> | (Well, from a Java webapp sitting on a WildFly server.) |
| 12:41 | <@Tarinaky> | Pop up a window asking the User to send an email. |
| 12:48 | < Julius> | Not applicable. This is part of a user-independent process. |
| 12:48 | <@TheWatcher> | JavaMail? |
| 12:48 | < Julius> | http://www.tutorialspoint.com/java/java_sending_email.htm <- I'm trying to use this, but I get "com.sun.mail.util.MailConnectException: Couldn't connect to host, port: localhost, 25; timeout -1;". |
| 12:49 | <@TheWatcher> | So, your server's actually running a smtp server, right? |
| 12:50 | < Julius> | Probably not. I haven't configured that, if it exists. |
| 12:50 | <@Tarinaky> | Then that'll be why it can't connect to the smtp server on localhost. |
| 12:51 | <@TheWatcher> | You'll either need to set up a smtp server, or use an existing one on another machine that'll relay for you |

| 14:39 | <@TheWatcher> | ffff |
| 14:40 | <@TheWatcher> | Of course there's somewhere I need to get to this function from, but can't |
| 14:40 | | * TheWatcher starts rearranging |
| 14:44 | <@Tarinaky> | Okay. I have no idea what Octave is doing to come up with the correct answer. |
| 14:44 | <@Tarinaky> | (GNU Octave) |
| 14:45 | <@Tarinaky> | I'm using wavread to load in a 2-channel WAV file. Which I noticed is represented in the program like a 2xN matrix (where N is the number of samples) |
| 14:45 | <@Tarinaky> | I wanted to 'flatten' the 2 channel vector into a 1-channel vector. |
| 14:46 | <@Tarinaky> | So, I multiplied the input by [1 0;0 0] and [0 0;1 0] then added the two products together. |
| 14:46 | <@Tarinaky> | This gives me a mono-channel signal. |
| 14:46 | <@Tarinaky> | But... WTF |
| 14:46 | <@Tarinaky> | The dimensions of the matrices don't match up so WTF is Octave doing |
| 14:47 | <@Tarinaky> | M[2xN] * M[2x2] should be undefined for N!=2 |
| 14:48 | <@Tarinaky> | What am I missing here? |
| 15:01 | <@Wizard> | Are you sure the first one isn't Nx2? |
| 15:01 | <@Wizard> | Only way that seems to make sense |
| 15:02 | <@Tarinaky> | The output (after pruning the 0-value column) is a column vector N long. |
| 15:02 | <@Tarinaky> | M[Nx2] * M[2x2] = M[2x2] |
| 15:02 | <@Tarinaky> | Still doesn't make sense. |
| 15:03 | <@Wizard> | Nnnno, Nx2 * 2x2 = Nx2 |
| 15:03 | <@Tarinaky> | Oh. |
| 15:03 | <@Tarinaky> | Of course it is! |
| 15:08 | | * Tarinaky always gets confused about which is width and height >.<) |
| 15:09 | <@Wizard> | Tarinaky: The easy mnemonic for it is abbc |
| 15:09 | <@Wizard> | AxB * BxC = AxC |
| 15:09 | <@Tarinaky> | Wizard: That's not what I get confused about |
| 15:09 | <@Tarinaky> | What I get confused about is whether A corresponds to the width of the vector, or its height |
| 15:09 | <@Wizard> | Easy mnemonic there too: the reverse of how your typical graph plotting works |
| 15:10 | <@Tarinaky> | That's not really a mnemonic. |
| 15:10 | <@Wizard> | Not in words, no |
| 15:10 | <@Wizard> | But the idea that it's in reverse is |
| 15:11 | <@Tarinaky> | "You know that thing that's the convention everywhere else? Well now you need to remember this one specific domain where it's the other way around for no discernable reason other than the fact your Professors in university hated you" |
| 15:11 | <@Wizard> | More likely reason: x is usually the set of specific values and y is the scale |
| 15:11 | <@Tarinaky> | That's like... the opposite of a nmemonic :P |
| 15:11 | <@Wizard> | And writing a tall matrix is easier than a wide one |
| 15:12 | <@Wizard> | "Matrix dimensions in reverse" is specific enough |
| 15:20 | <@Tarinaky> | Argh, so. |
