| 04:07 | <&McMartin> | Unfortunately for me, many of these docs are in German |
| 04:07 | <&McMartin> | Fortunately, though, the German word for "high impedance" is "hochohmig" and I find this implausibly charming |
| 04:07 | <&McMartin> | "High-ohm-ish" |

| 10:22 | < simon_> | *spending 5 minutes convincing new developer that his AJAX route shouldn't return HTML, but JSON* |
| 10:26 | <&[R]> | :/ |
| 10:28 | <&[R]> | Then 30 minutes later their idiot-disease resurfaces and you have the exact same discussion? |
| 10:33 | <@TheWatcher> | ... why is he trying to return html anyway? |
| 10:48 | < simon_> | TheWatcher, because then his AJAX success handler can just tack the result on to the DOM. |
| 10:51 | <@TheWatcher> | Ahwell, we've all done dumb things sometimes - hopefully the lesson will stick |
| 11:09 | < ErikMesoy> | And if not, apply stick to developer? |

| 13:50 | <&ToxicFrog> | This is extremely cool (a memory allocator that reduces physical memory usage by merging partially allocated pages): https://arxiv.org/pdf/1902.04738.pdf |
| 13:58 | < simon_> | TheWatcher[d00m], yeah, this guy has a bad habit of laughing when I propose something he could improve. I initially disregarded it as a nervous laughter, but when he eventually tacked on a "that's fucking dumb", I've shifted to a more authoritarian attitude towards him. sadly it works. now he's relieved when I say "meh, just hack that." |
| 13:59 | < simon_> | I bet that's how women in tech feel like most of the time... :/ |

| 16:10 | <~Vornicus> | arg, block scope + forced local for loop variables = sadness. http://pastebin.starforge.co.uk/29 in Lua: can you find a nicer way to do this than with curr_face? |
| 16:47 | | Kindamoody|afk is now known as Kindamoody |
| 17:03 | | Emmy [Emmy@Nightstar-9p7hb1.direct-adsl.nl] has joined #code |
| 18:25 | <&ToxicFrog> | Ok, so to make sure I understand what this is doing -- it scans the contents of the face_heirarchy to find the face containing the point, then recurses into the children of that to find the subface containing it, etc, until it finds a face with no children, which is the containing face? |
| 18:26 | <~Vornicus> | well, it scans the children of face_hierarchy[1], recurses, etc |
| 18:28 | <~Vornicus> | But yeah. (face_hierarchy is a list here, not the root of the tree, and children index into face_hierarchy, as opposed to using pointers, which suck for reasons having to do with needing to do things to *everything* later, which means either traversal or having an array) |
| 18:32 | <&ToxicFrog> | Vornicus: http://pastebin.starforge.co.uk/30 |
| 18:34 | <&ToxicFrog> | ✨ tail recursion ✨ |
| 18:34 | | * Vornicus examines |
| 18:36 | <~Vornicus> | Oh I see. I was wondering why you're passing true_on on, and it's because you don't get it back in the leaf node. |
| 18:36 | <&ToxicFrog> | Yeah. |
| 18:36 | <&ToxicFrog> | There might be a more convenient way to structure this where you end up calling that on the leaves, hmm |
| 18:36 | <~Vornicus> | All right let's try this one |
| 18:36 | | * ToxicFrog tinkers |
| 18:37 | <&ToxicFrog> | wait, no, should not get nerdsniped while in the middle of code reviews |
| 18:37 | <~Vornicus> | thank you for reviewing my code~ |
| 18:37 | <&ToxicFrog> | Anyways, IMO the explicitly recursive version is clearer; the iterative version is just the recursive version with the arguments pulled out into their own variables |
| 18:38 | <~Vornicus> | yeah it makes a decent amount of sense |
| 18:40 | <~Vornicus> | and after including the `end` for your `if`, tests are green |
| 18:40 | <&ToxicFrog> | Whoops |
| 18:41 | <~Vornicus> | yeah it ain't C-shaped |
| 18:48 | <~Vornicus> | it'd go something like... try it on myself; if it doesn't work return false, if I've got children loop over with recursion and return the first one that comes back truthy, if I don't have children return my own data |
| 18:49 | <~Vornicus> | I need to remember inner functions are a thing |
| 18:52 | <&ToxicFrog> | It doesn't need to be inner, you could declare it as an external local function and pass fh in explicitly, but when it's just used as a helper function and never meant to be called directly I prefer to put it inside the function it helps. |
| 19:28 | <~Vornicus> | There. |
| 19:29 | <~Vornicus> | http://pastebin.starforge.co.uk/31 |
| 19:33 | <&ToxicFrog> | Note that that version is no longer tail-recursive and requires O(depth of face heirarchy) space. |
| 19:35 | <~Vornicus> | I'll live |
| 19:35 | <&ToxicFrog> | Ok. I wasn't sure how much of a concern that was. |
| 19:36 | <~Vornicus> | the face hierarchy is O(log (number of points in the mesh)) or so deep |
| 19:37 | <~Vornicus> | and I'm not breaking a thousand points typically |
