| 08:54 | | * McMartin prods old sprite formats. |
| 08:55 | <&McMartin> | I spend a fairly alarming amount of time messing around in a Python REPL with struct imported. |
| 09:38 | | * McMartin gets a text representation of the sprite out! |
| 09:38 | <&McMartin> | This 8-bit truecolor mode arranges its bits BGGRBRKK, wtf |
| 09:39 | <&McMartin> | ("KK" is the lower two bits of R, G, and B all at once) |
| 09:39 | <@gnolam> | Err |
| 09:41 | <@TheWatcher> | .... whaaaa |
| 09:41 | <@TheWatcher> | Why would you do that?! O.o |
| 09:42 | <&McMartin> | I acknowledge and respect that the UK went its own way with personal computing, but Acorn, what is wrong with you. |
| 09:42 | <&McMartin> | Also why are icons 34x17x256 with all scanlines doubled, you are being plugged into the equivalent of a Super VGA monitor |
| 09:46 | <&McMartin> | Note that if you are using a 64-color mode it's 00BBGGRR like the rest of those circuits designed by human beings or their creations |
| 09:49 | <&McMartin> | I'll even grant that while I haven't seen that gamut before it makes sense |
| 09:49 | <&McMartin> | If the chip can theoretically do 12-bit color but your video ram kind of just wants to use 8 bits per pixel, "Those colors in the 12-bit space where the lower two bits of R, G, and B are the same value" is a reasonable choice. |
| 09:50 | <&McMartin> | (There seems to be a programmable palette, but that is kind of grimly hilarious when you try to use it in a desktop environment) |
| 09:50 | <&McMartin> | tl;dr: man, it was way easier to learn to program in the late 1980s than the early-mid 1990s. |
| 09:51 | <&McMartin> | (We won't discuss the PC BIOS's idea of a sensible default 256-color palette.) |
| 09:52 | <&McMartin> | (Because we don't have to! Standard practice was to pick your own 256 from the 24-bit truecolor space that BIOS provided.) |
| 09:52 | <&McMartin> | (... but that it turns out VGA secretly didn't, which I didn't learn until like three months ago.) |
| 10:06 | <@TheWatcher> | Hey, at least it didn't use bitplanes~ |

| 13:07 | | * Vornicus reads, goes *whoosh* |
| 13:07 | <~Vornicus> | I suspect I'd need way more understanding of C++ templating to get what's going on there |
| 13:09 | <@abudhabi> | May or may not require some black goats. |
| 13:27 | < Jessikat> | ...I've gone too deep, haven't I |
| 13:29 | <&ToxicFrog> | Possibly. |
| 13:29 | | * ToxicFrog pokes it with a stick |
| 13:36 | < Jessikat> | :D |
| 13:36 | | * Jessikat shrugs |
| 14:29 | <&ToxicFrog> | One of the questions I have: is the anonymous function in the example inherently typed as std::function, or is it implicitly converted from a normal function pointer to that/ |

| 17:31 | < Jessikat> | ToxicFrog: std::function is just a normal templated type, the type of print_backwards is void (std::string) and the constructor of std::function will likely implicitly convert it to a function pointer to store internally |
| 17:31 | < Jessikat> | the mechanics of doing that are... a little hairy |
| 17:31 | < Jessikat> | but not that much code |

| 23:43 | | * McMartin fiddles with the binutils, drops this binary size from 33600 bytes to 140 bytes. |
| 23:44 | <@Alek> | o_o |
| 23:44 | <&McMartin> | For some reason ld keeps insisting on throwing 32KB of zeroes into these binaries. |
| 23:45 | <&McMartin> | I *think* it's because I want the text segment to start in a location that the ELF loader wants to keep the header |
| 23:45 | <&McMartin> | Whatever it's doing *works in the end*, but. |
| 23:45 | <&McMartin> | One can do better with more rigorous instruction. :) |
| 23:45 | <&McMartin> | Also, I am full of burritos now, I can try to read Jessikat's article. |
