| 00:26 | <&McMartin> | Ugh |
| 00:27 | <&McMartin> | So, for my Klotski-solving shootout, I've been thinking through what I'd need to do to solve it in C. |
| 00:27 | <&McMartin> | Doing it right involves "implement or borrow a balanced binary tree or hashmap implementation" and "write a simple refcounting garbage collector" >_< |
| 00:27 | <&McMartin> | So... that one non-speed-related argument right there |

| 11:21 | <@Tarinaky> | So. I have a large array, I want to split it into smaller subarrays of length N |

| 11:28 | <@Tarinaky> | I can only come up with hacky C-like ways of doing it. |
| 11:31 | <&McMartin> | Does Ruby have a Go-like notion of Slices? |
| 11:31 | <&McMartin> | (Are these subarrays supposed to be aliased to the big array, or copies of fragments of it?) |

| 11:31 | <@Tarinaky> | McMartin: Just copies. |
| 11:32 | < gizmore> | userids.each_slice(100) do |a| |
| 11:32 | < gizmore> | a.ha! |
| 11:32 | < gizmore> | end |
| 11:32 | <@Tarinaky> | Danke. |
| 11:34 | < gizmore> | my pleasure |
| 11:35 | < gizmore> | ruby has a quite elegant and short syntax, once you get used to it... my next language might be python :) |
| 11:35 | < gizmore> | but also it´s worth to try JRuby... not sure yet :) |
| 11:35 | <@Tarinaky> | I'm coming at it from Python |
| 11:36 | <@Tarinaky> | I find ruby syntax complicated and the online-documentation is difficult to index through looking for the right thing (I was looking at the docs for Array when I should have been looking at Enumerable) |
| 11:38 | <@Tarinaky> | It's certainly more terse than Python. |
| 11:38 | <@Tarinaky> | +though. |

| 12:40 | <@Tarinaky> | Hmm. Interesting idea I read on /r/gamedev. How would you implement the pre-rendered scenery/backgrounds from games like FFVII if you were to do it today for retrokitsch. |
| 12:41 | <@Tarinaky> | Obviously the motivation for doing it doesn't exist anymore on modern hardware but it did have a charm in the same way matte-painting backdrops did in movies. |
| 12:48 | <@Tarinaky> | The big issue is if you go ostentatious with the animation it's going to use up a lot of texture memory per frame. |
| 12:48 | <@Tarinaky> | I'm not sure how much of a show-stopper that is. |
