| 04:53 | | * Vornicus gets the design document written. Needs to figure out mouse picking in pygame, but that's not a big problem. |
| 04:54 | <&jerith> | Mouse picking? |
| 04:55 | <~Vornicus> | Mouse picking: selecting objects by the mouse. |
| 04:55 | <&jerith> | Ah. |
| 04:55 | <&jerith> | You need a widget library of some kind, probably. |
| 04:56 | <&jerith> | We've written several. |
| 04:56 | <~Vornicus> | I don't need many widgets. |
| 04:57 | <&jerith> | I think the most useful is in http://ctpug.org.za/wiki/MutableMamba |
| 04:57 | | * Vornicus pokes at SupComm 1 which is having sound issues. few if any sounds are playing. |
| 04:58 | <&jerith> | Or maybe http://ctpug.org.za/wiki/SuspendedSentence |
| 04:58 | <&jerith> | Actually, Suspended Sentence might be better for your needs. |
| 04:59 | <&jerith> | There are a bunch of widgets for menus and stuff (mostly wrapped around a different library) and a big "game board" thing that handles its own magic. |

| 20:42 | | simon_ [simon@Nightstar-fe311ff3.pronoia.dk] has joined #code |
| 20:43 | < simon_> | so I'm looking at this programming assignment from an old exam: find the largest divisor in N that doesn't have repeating prime divisors itself. |
| 20:44 | <~Vornicus> | Basically you'll have to pull out straight up prime factorization, I think |
| 20:44 | < simon_> | yeah, my question is if I can avoid that. |
| 20:45 | <~Vornicus> | Not as far as I'm aware. |
| 20:45 | < simon_> | perhaps only look for prime divisors until repeating ones are found, and perhaps start by looking at big divisors rather than small. |
| 20:46 | <~Vornicus> | Start with small ones. |
| 20:46 | <~Vornicus> | And eat even repeating ones - dividing something by two can significantly reduce the number of primes you need to test. |
| 20:48 | <~Vornicus> | dividing by a larger number can crush it down even more. |
| 20:56 | < simon_> | repeating prime factors* |
| 20:57 | <~Vornicus> | (if you have a number around 1 million, you have to go through 168 primes to completely cover all your bases; if you pull out a 2, you need to check 126 primes total afterwards, saving you 42 divisions) |
| 21:00 | <~Vornicus> | But: I don't think there's a better method because the existence of a better method would point to a vastly better method for prime factorization. |
| 21:01 | < simon_> | hmm |
| 21:01 | < simon_> | ok |
| 21:01 | < simon_> | reasonable. |
| 21:01 | < simon_> | so I prime factorize n, weed out repeating primes and take the product of the rest. |
| 21:05 | <~Vornicus> | basically. |
| 21:05 | <~Vornicus> | Since you find all repetitions of a particular prime right next to each other, you can make the weed-out very practical. |
| 21:09 | <~Vornicus> | http://oeis.org/A007947 anyway. |
| 21:11 | < simon_> | thanks! |
| 21:53 | | celmin|awayfood is now known as celticminstrel |
| 22:04 | | Derakon[AFK] is now known as Derakon |
| 22:04 | <&Derakon> | Bleh. |
| 22:05 | <&Derakon> | I'm the only person on the Angband development team that wants to use Mercurial instead of Git. |
| 22:05 | <~Vornicus> | bleh |
| 22:06 | <&Derakon> | My repo is the main repo, and it's in Mercurial...but it's clearly enough of a problem that devs aren't contributing because they don't want to learn it / adjust their development philosophies. |
| 22:06 | <&Derakon> | Angband devs reeaaaaallly like being able to delete branches. |
| 22:10 | < celticminstrel> | ...you can't delete branches in hg? |
| 22:11 | <&Derakon> | Mercurial, like most content versioning systems, does not let you delete commits. |
| 22:11 | <&Derakon> | Except for the most recent one, in case you fat-fingered something. |
| 22:12 | < celticminstrel> | Branches aren't commits though... |
| 22:12 | <~Vornicus> | wait, angband dev or pyrel dev? |
| 22:12 | <&Derakon> | Pyrel dev. |
| 22:12 | <&Derakon> | CM: a branch doesn't exist until you commit to it. |
| 22:12 | <&Derakon> | By deleting a branch you delete all the commits in it. |
| 22:13 | < celticminstrel> | Um. |
| 22:13 | <~Vornicus> | yeah, was about to say, when did you become maintainer of angband itself |
| 22:13 | < celticminstrel> | That's not what a branch is in git, is it. |
| 22:13 | <&Derakon> | Vorn: well, to the extent that most Angband dev work currently is on Pyrel~ |
| 22:13 | < celticminstrel> | Isn't a git branch more like a symlink or something? |
| 22:14 | <~Vornicus> | heh |
| 22:14 | <&Derakon> | A git branch is a new head that splits off of one line of commits after some specific commit. |
| 22:15 | < celticminstrel> | Okay, and...? |
| 22:15 | <&Derakon> | Heads are sequences of commits. |
| 22:16 | <&Derakon> | So when you delete a head (i.e. branch), you also delete those commits. |
| 22:16 | <&Derakon> | Unless you merged them back into mainline at some point. |
| 22:16 | < celticminstrel> | That doesn't sound right... |
| 22:16 | < celticminstrel> | But maybe that's just because of garbage collection or something. |
| 22:16 | < celticminstrel> | But why shouldn't you be able to delete a commit? |
| 22:17 | <~Vornicus> | why should you delete a commit? |
| 22:18 | < celticminstrel> | Because you started a branch, worked on it for a bit, then after making a few commits thought of a completely different and much better way to do what you were trying to do, such that starting back at the branch point would be easier than starting at the head of your branch? |
| 22:19 | <&McMartin> | Because 2/3s of the way through that you may realize why you were right the first time |
| 22:20 | <&Derakon> | Hard disk space is cheap~ |
| 22:20 | <&Derakon> | Mercurial, unlike Wikipedia, does not support a deletionist philosophy~ |
| 22:20 | < simon_> | I just read about Curry's paradox. I like it. |
| 22:21 | | * McMartin kind of suspects git is so hardcore about annihilating branches because Subversion doesn't let you~ |
| 22:23 | < celticminstrel> | Yes, but once you have one or other of the ways finished and working, you don't really need the other one anymore. |
| 22:24 | <&Derakon> | Nor is it getting in the way -- and you may always want a reminder of why you took the path you did. |
| 22:25 | < celticminstrel> | I dunno. It just seems silly to disallow something so basic as deletion. |
| 22:27 | <&McMartin> | Disallowing deletion is traditionally what VCSes are *for*. |
| 22:27 | < celticminstrel> | Not exactly. |
| 22:27 | <&McMartin> | Also |
| 22:27 | <&McMartin> | It's not like mercurial doesn't disallow *reverting*. |
| 22:27 | <&McMartin> | Reverting is what replaces deletion. |
| 22:27 | < celticminstrel> | Oh? Howso? |
| 22:27 | <&McMartin> | The thing git partisans whine about is "why isn't it trivial in other systems ot edit history" |
| 22:28 | <&McMartin> | I am at reversion 10. |
| 22:28 | <&McMartin> | I do some work, am now at revision 12. |
| 22:28 | <&McMartin> | Realize this is a mistake. |
| 22:28 | <&McMartin> | Revert commits 11 and 12. |
| 22:28 | <&Derakon> | Mercurial reversion is basically "Let's replace the current head with what the head was 2 commits ago" or whatever. |
| 22:28 | <&McMartin> | Now if we commit that revision 13 is what revision 10 was, but you probably also do extra work after that. |
| 22:29 | <&McMartin> | Modern systems don't store changes as deltas, so there's actually no reason other than bookkeeping to even make note of that |

| 23:06 | < celticminstrel> | It's stupidly obtuse and inextensible, but it's nice despite that. |
| 23:12 | <~Vornicus> | Headings are kind of cool. |
| 23:12 | <~Vornicus> | THey're not as cool as they could be, but they're kind of cool. |
| 23:13 | < celticminstrel> | Yeah. |
| 23:13 | < celticminstrel> | I think that's a good way of putting it. |
| 23:17 | | * McMartin has been reminded that https://www.youtube.com/watch?v=o72T8qQr7GE was an actual ad |
| 23:19 | <@Tamber> | ahaha |
| 23:19 | <&McMartin> | The trigger for the memory was the phrase "tender, all white-meat chickens" |
| 23:19 | <&McMartin> | Then it turned out it was on YouTube because of course it was. |
| 23:20 | < celticminstrel> | o.O Tomato surprise. |
| 23:20 | <&McMartin> | The ad is actually funnier now that CUDA and OpenCL are things. |
| 23:26 | <@TheWatcher> | McM: I don't rely on that, given that YouTube lacks the best Toffee Crisp advert ever |
| 23:27 | <&McMartin> | Clearly, some intrepid pirate needs to upload it |
| 23:28 | < Moltare> | It does have most of the good Tango ads, though |
