| 04:54 | <@ToxicFrog> | One thing that's always bugged me about dynamic programming |
| 04:54 | <@ToxicFrog> | Why do we have another name for what is, at the end of the day, memoization? |
| 04:54 | <@McMartin> | "memoization" sounds retarded~ |
| 04:55 | <@ToxicFrog> | "dynamic programming" sounds like self-modifying code~ |
| 04:55 | <@ToxicFrog> | Or runtime code generation. |
| 04:55 | <@ToxicFrog> | Whatever it is, it sounds nothing at all like "let's cache the results from this pure function |
| 05:36 | | * Derakon tries to figure out why "open('spells.txt', 'r')" is failing with a "No such file or directory" error when the file is right there. |
| 05:37 | | Orthia [Orthianz@Nightstar-df05ce59.xnet.co.nz] has quit [Client closed the connection] |
| 05:37 | <@Vornicus> | in the right directory? |
| 05:37 | <@Derakon> | Oh, wait, first arg is the variable to assign the filehandle to. Right. |
| 05:38 | <@Derakon> | Okay, now I need to figure out a pattern that will capture the different variations in e.g. "Set the counter die for this spell to [2],[3]". |
| 05:39 | <@Derakon> | Hrm. What's the right brackets/braces to use for "this substring may be repeated"? |
| 05:39 | <@Derakon> | In a regex. |
| 05:41 | <@Derakon> | /{(\[[^\]]*?\]),?}*/ is certainly wrong. |
| 05:43 | <@ToxicFrog> | () is usually grouping |
| 05:43 | <@ToxicFrog> | (substr)* |
| 05:43 | <@Derakon> | It's also capture in Perl, though... |
| 05:44 | <@ToxicFrog> | Is it capture+group,or just capture? |
| 05:44 | <@Derakon> | Um...I'm afraid I don't understand the question. What do you mean by group? |
| 05:45 | | Orthia [Orthianz@Nightstar-df05ce59.xnet.co.nz] has joined #code |
| 05:50 | <@Derakon> | Okay, I have it working to the extent that it gets the first of the options. |
| 05:50 | <@Derakon> | With /(?:(\[[^\]]*?\]),?)/ |
| 05:50 | <@Derakon> | The ?: construct does clustering without reporting the stuff inside the parens as a match. |
| 05:51 | <@Derakon> | That's not repeating the pattern...but if I try to repeat it, I get errors out of Perl. |
| 06:00 | <@Derakon> | Ahh! Needed the /g option! |
| 06:00 | <@Derakon> | Final pattern is /(?:\[([^\]]*?)\],?)/g |
| 06:00 | <@Derakon> | Go line noise! |
| 06:03 | | Syloqs-AFH [Syloq@NetworkAdministrator.Nightstar.Net] has quit [Connection reset by peer] |
| 06:05 | <@ToxicFrog> | By "group" I mean "this is treated as a single element for the purposes of *+? and similar" |
| 06:06 | <@ToxicFrog> | "() groups" is true if /^(foo)+$/ matches 'foo' or 'foofoo' but not 'foooo' |
| 06:20 | <@McMartin> | Woo, solved #111 in just over a second of realtime and just under a second of usertime. |
| 06:20 | <@Derakon> | Nice. |
| 06:21 | <@McMartin> | And again, with nothing fancier than trial division, despite having to enumerate 10-digit primes. |
| 06:23 | | * Vornicus was never getting anywhere near that performance with trial division for primes. |
| 06:24 | <@McMartin> | The trick is in ensuring that by the time filter check_prime x is called, x has already been largely culled and/or generated small in the first place. |
| 06:25 | <@McMartin> | I actually expected to need to do some additional prefiltering too but once again I overestimated the cost of multiple precision integer math. |
| 06:26 | <@McMartin> | If it was multiple precision at all, really; those are all int64s. |
| 06:29 | <@McMartin> | I'm beginning to get the feeling that if you actually need Miller-Rabin and friends, this is now evidence that you designed the algo wrong. |
| 06:30 | <@Derakon> | Ha HA! http://derakon.dyndns.org/~chriswei/games/magewar/spellcards.html |
| 06:30 | <@Derakon> | Phew. |
| 06:31 | <@Derakon> | "dx" should be read as "use the die you used as a counter for the spell". |
| 06:31 | <@Derakon> | Hm...minor typo in the Frostwyrm's Breath definition. |
| 06:32 | <@Derakon> | Okay, so I still have some bugs to sort out. ¬.¬ |
| 06:32 | | * Derakon eyes the six entries for Meditation when there should only be three. |
| 06:33 | <@Derakon> | ...oh. It's because I had two different option splits in the Meditation spell description. :( |

| 12:37 | <@AnnoDomini> | I think I'll ask around in the official channel. How do I create a new status window for a new server? |
| 12:37 | <@AnnoDomini> | I don't want to simultaneously leave NS. |

| 21:15 | | You're now known as TheWatcher |
| 21:19 | < gnolam> | ... delete[]? How hard is that? |
| 21:23 | <@McMartin> | given an int*, you cannot know without extended reasoning about the entire program whether it must be freed with delete or delete[] because there is no distinguisher between the types. |
| 21:23 | <@McMartin> | Unless it's local and doesn't escape, in which case you shouldn't really be using new anyway. |
| 21:26 | <@ToxicFrog> | Why the hell is it type name[size] and not type[size] name, anyways? |
| 21:34 | <@McMartin> | Because the size is not part of the type, because they're all type*. |
| 21:34 | <@McMartin> | Except that if you delete it it will permanently corrupt your heap. |
