| 00:00 | <@ToxicFrog> | Is there something like instanceof that lets me ask "does this thing implement this interface"? |
| 00:01 | <@ToxicFrog> | So that I can say, for example: if( !(Thread.currentThread() implementorof MessagePassing) ) { throw new InvalidMessagePassContextException(); } else { /* do stuff */ } |
| 00:04 | <@McMartin> | Yeah, instanceof does that. |
| 00:05 | <@ToxicFrog> | Aah. |
| 00:05 | <@McMartin> | If you actually want "Is this object of precisely this class" you need to do obj.getClass().equals |
| 00:05 | <@ToxicFrog> | Yeah, I just want to know if it implements the MessagePassing interface. |
| 00:05 | <@McMartin> | instanceof MessagePassing. |
| 00:05 | <@ToxicFrog> | Right. |
| 00:05 | <@ToxicFrog> | (because sending an interthread message from a thread that doesn't implement it is an error, as it leaves no way to reply()) |
| 00:06 | <@McMartin> | Java's reflection mechanism is just ugly enough that you won't want to use it much, but the basic bits (getClass(), Class.forName(), Class.newInstance()) are relatively easy, and all the power is there when you really need it. |
| 00:07 | <@McMartin> | Oh, and 1.5 makes the static .class field official, IIRC, but I'm a bit unclear on that one, because of Standard McM Java Caveat 1. |
| 00:07 | <@McMartin> | (And the question was "which is the rc") |

| 00:08 | | * ToxicFrog snrks at Moodle |
| 00:10 | <@ToxicFrog> | So, Moodle is this open-source web teaching thing a bunch of the CIS courses are using. |
| 00:10 | <@ToxicFrog> | To enrol in a course, you need a key, which is provided by the prof. |
| 00:10 | <@ToxicFrog> | (a passphrase, that is, not a cryptographic key) |
| 00:10 | <@ToxicFrog> | If you get it wrong, it will tell you so, and "here's a hint: it starts with '%c'" |
| 00:11 | <@ToxicFrog> | The %c has no relation to what the key actually starts with. |
| 00:13 | | ReivSLEP is now known as ReivClass |
| 00:15 | <@gnolam> | Ehm. |
| 00:29 | <@ToxicFrog> | ...oh, arse |
| 00:29 | <@ToxicFrog> | Forgot all about exception signatures |
| 00:33 | < Vornicus> | Does eclipse warn about exception signatures live? |
| 00:35 | <@ToxicFrog> | No idea. McM? |
| 00:35 | < Vornicus> | it probably does. |
| 00:36 | < Vornicus> | or, "live" in the sense of "whenever it gets a moment to see what you've done" |
| 00:36 | <@ToxicFrog> | (the issue here is that the possible exceptions are all totally different - interthread might throw InterruptedException, whereas intersystem can definitely throw IOException and probably an assload of other, socket-specific exceptions) |
| 00:36 | <@ToxicFrog> | (I may need to catch them in the message passing functions and translate to MessagePassException) |
| 00:47 | <@McMartin> | I don't really use Eclipse much |

| 04:29 | < Darius> | don't you mean s/e\././ ? |
| 04:29 | <@Derakon> | Er, yes. ¬.¬ |
| 04:33 | <@Derakon> | Okay, I want map. |
| 04:33 | <@Derakon> | I have a function "scale" and a list/array/whatever you call it "localCoords". |
| 04:34 | <@Derakon> | foo = [scale(2, coord) for coord in localCoords] |
| 04:34 | <@Derakon> | That doesn't work. |
| 04:34 | <@Derakon> | ...oh, wait, namespace collision. |
| 04:35 | | * Derakon can now generate scaled pyramids, yay. |
| 04:35 | <@Derakon> | Now to generate Pascal's pyramid. |
| 04:38 | <@Derakon> | Is there some kind of "[0..100]" equivalent in Python (to generate a list containing the numbers 0 through 100)? |
| 04:39 | <@Derakon> | ..."range(0, 100)". Right. |
| 04:42 | < Darius> | range(0,101). It's inclusive left and exclusive right. |
| 04:42 | <@Derakon> | Ahh. |
| 04:42 | < GeekSoldier|bed> | range(0,101) |
| 04:42 | < Darius> | Also technically it's just range(101), because it's implied 0 for the left. |
| 04:42 | | GeekSoldier|bed is now known as GeekSoldier|work |
| 04:43 | < GeekSoldier|work> | yeah. |
| 04:43 | < Darius> | there's also xrange, if you want an iterator. |
| 04:43 | <@Derakon> | I seem to be okay with "for offset in range(foo, bar):" |
| 04:43 | <@Derakon> | Though, uh, I'm not getting the pyramids I expect from it. |

| 04:49 | <@Derakon> | Sorry! |

| 05:48 | < GeekSoldier|work> | that looks proper, Derakon, but it's been a while since I've written for blender. |

| 06:38 | <@Derakon> | That's proper because it was copied from an example. |

| 06:45 | | ChalcyAFK is now known as Chalcedon |
| 06:46 | <@Derakon> | Okay, how do I convince Python to give me a floating point result from dividing integers? |
| 06:46 | <@Derakon> | The old "insert a .0 on the end" trick doesn't work. |
| 06:47 | < jerith> | At least one of the operands must be a float. |
| 06:47 | < GeekSoldier> | float(int/int) |
| 06:47 | < GeekSoldier> | bah. |
| 06:47 | < GeekSoldier> | float(int)/int |
| 06:48 | <@Derakon> | No joy... |
| 06:49 | <@Derakon> | for offset in range(-8, 8): func(offset / float(4)) |
| 06:49 | <@Derakon> | The argument passed in has value 2, 1, 1, 1, 1... |
| 06:49 | | Darius is now known as Vornicus |
| 06:50 | <@Derakon> | Vorn! You know Python! |
| 06:50 | | * Vornicus knows Python! |
| 06:50 | <@Derakon> | Help me delude Python into giving me floating point values! |
| 06:50 | < Vornicus> | I'm surprised it isn't. |
| 06:51 | < Vornicus> | indeed, it works fine here. |
| 06:51 | < jerith> | For me too. |
| 06:51 | | Chalcedon [~Chalcedon@Nightstar-2472.ue.woosh.co.nz] has quit [Quit: rebooting] |
| 06:52 | < jerith> | Perhaps func() is casting it back to an integer? |
| 06:52 | < Vornicus> | >>> for offset in range(-8,8): print offset/float(4) |
| 06:52 | < Vornicus> | ... |
| 06:52 | < Vornicus> | -2.0 |
| 06:52 | < Vornicus> | -1.75 |
| 06:52 | < Vornicus> | yadda yadda |
| 06:52 | <@Derakon> | Hrm...maybe it's Blender that's cracked out, then. |
| 06:52 | <@Derakon> | I just did it in the Python interpreter directly and it worked. |
| 06:53 | < GeekSoldier> | what version python was it using? |
| 06:53 | < Vornicus> | Wouldn't surprise me. Blender is some crazy shit. |
| 06:53 | <@Derakon> | I thought it used the Python installed on my box, but I could be wrong. |
| 06:54 | < GeekSoldier> | for a while, it refsed to see my installed python. now with the latest update, it sees Python 2.5 and is happy with it. |

| 21:08 | < Vornicus> | Wow, really? |
| 21:09 | <@ToxicFrog> | The job of generating prettyprinted documentation, IIRC. |

| 21:27 | <@jerith> | It's nastier to write, though. |
| 21:29 | <@McMartin> | Yes. |
| 21:29 | <@McMartin> | And DocBook seems kind of hopeless for generating usable TeX. I must be missing some .sty file. |
| 21:30 | <@McMartin> | Or other library, because there's a bunch of commands it's not understanding. |
| 21:31 | <@jerith> | McMartin: It has only a small subset of the functionality. |
