| 00:24 | < Rhamphoryncus> | Just looked it up.. sure, only a few pieces, but each is composed of infinitely many points :P |
| 00:26 | <&McMartin> | So is every line segment~ |
| 00:28 | < Rhamphoryncus> | yup, which is interesting, but not nearly as interesting as the b-t paradox |
| 00:28 | < Rhamphoryncus> | err |
| 00:28 | < Rhamphoryncus> | not nearly as interesting as the b-t paradox is portrayed to be |

| 00:33 | <&McMartin> | Remember when we were bitching about Sun build systems yesterday |
| 00:33 | <&McMartin> | I went to look at VBox's build instructions again to see if the Windows build still required a MinGW-hosted cross-compiler that targets 64-bit Linux |
| 00:33 | <&McMartin> | It does |
| 00:33 | <&McMartin> | But they now officially apologize for this |
| 00:34 | <&ToxicFrog> | wait |
| 00:34 | <&ToxicFrog> | what |
| 00:34 | <&McMartin> | https://www.virtualbox.org/wiki/Windows%20build%20instructions |
| 00:34 | <&McMartin> | Originally, this requirement was *completely undocumented* |
| 00:35 | <&McMartin> | So if you tried to build the OSE version from source you'd get, on windows, "cannot find gcc-i686-linux-elf.exe, aborting" |
| 00:35 | <&McMartin> | Also, you have to hand-hack the gcc sources to get something that mingw will compile and run, and you need a Linux system to use as sysroot. |

| 00:36 | <&McMartin> | That said, poking around their site, Oracle has *seriously* gotten Sun's and Innotek's shit together |
| 00:37 | <&McMartin> | Like, there is actual SDK documentation now |
| 00:38 | <&McMartin> | (IIRC, the MinGW cross-compiler jackassery is because VBox does binary recompilation of guest executable code to replace I/O with hypervisor traps.) |

| 01:25 | <&McMartin> | Not only is there actual SDK documentation, it's actually pretty good |
| 01:25 | <&McMartin> | Also python bindings \o/ |
| 01:25 | <~Vornicus> | \o/ |
| 01:38 | <&ToxicFrog> | Oh yeah, what's libgdx? |
| 01:41 | <&McMartin> | It appears to be a Java game development library targeting desktop, Android, and WebGL/HTML5. |
| 01:42 | <&McMartin> | http://libgdx.badlogicgames.com |
| 01:43 | <&McMartin> | Came up on ifMUD, I am bookmarking it for future reference |
| 01:43 | <&McMartin> | I don't think I'd use it for Hex Inverter unless the Android port of it stalls. |
| 01:45 | <&ToxicFrog> | oho |
| 01:45 | <&ToxicFrog> | That reminds me, I should look into Android development; there's an app I want to write |
| 01:46 | <&McMartin> | This got a "the docs are much more solid now and it seems OK so far" for game-y stuff |
| 01:46 | <&McMartin> | For app-y stuff, developer.android.com pretty much has the goods |
| 01:46 | <&ToxicFrog> | Yeah, this would in fact be an app, not a game |
| 01:47 | <&McMartin> | And I've also got an API 10 phone if you want extra testing space~ |
| 01:47 | <&ToxicFrog> | (there is also a game I want to write but I do not think it would work well on mobile devices) |

| 15:22 | < Tarinaky> | Sod it. I'll just eat the inevitable memory leaks from this terribly written library I did as a lark :/ |
| 15:25 | | * TheWatcher eyes channel |
| 15:26 | <@TheWatcher> | jasoncpp? |
| 15:26 | <@TheWatcher> | *jsoncpp |
| 15:27 | <@TheWatcher> | http://jsoncpp.sourceforge.net/ - that thing. I've heard some decent things about it |
| 15:28 | < Tarinaky> | In fairness, I think my version is fairly close to correct. It's just there's a few bits of it I'm wtf-ing at myself for. |
| 15:29 | <&McMartin> | JSON is by design Not Hard |
| 15:29 | <&McMartin> | Part of the problem, really |
| 15:29 | < Tarinaky> | McMartin: And yet Boost, somehow, manages to fuck it up. |
| 15:30 | <&McMartin> | Looks like a template instantiation gone awry |
| 15:30 | < Tarinaky> | In the end it came down to the fact that Boost absolutely -had- to have a file and there was nop scope for passing it any other kind of stream. |
| 15:31 | < Tarinaky> | Which is a pain when you're not using standard file io >.> |
| 16:08 | <&ToxicFrog> | wait, what? |
| 16:09 | < Tarinaky> | Physfs. |
| 16:09 | <&ToxicFrog> | does C++ even have a file type? I thought it was iostreams all the way down |
| 16:09 | <&McMartin> | It does have a file type; it's what ifstreams and ofstreams wrap~ |
| 16:09 | < Tarinaky> | iostreams are instantiated from file handles typically... iirc. |
| 16:11 | <&McMartin> | The error quoted involved something looking for but not finding the str() method |
| 16:11 | <&McMartin> | That's part of ostringstreams. |
| 16:11 | < Tarinaky> | I long since gave up on that. |
| 16:29 | < Tarinaky> | Now I just have to swear at ld for being a pain. |
| 16:38 | < Tarinaky> | Oh wait, it wasn't boost not throwing an exception.. it seems this version of gdb isn't halting on exception. |
| 16:40 | <@TheWatcher> | Are you actually telling it to? >.> |
| 16:40 | < Tarinaky> | On Linux I have a recollection of it giving a different message if there's an exception. |
| 16:41 | < Tarinaky> | Anyway. PHYSFS isn't openning a file for writing for some reason. |
| 16:41 | < Tarinaky> | There's a function to get the last error message though... |
| 16:41 | <@TheWatcher> | before you run the program, issue 'catch throw' and it should stop when the exception gets thrown. |
| 16:41 | < Tarinaky> | (gdb) print PHYSFS_getLastError() |
| 16:41 | < Tarinaky> | $1 = 0x0 |
| 16:41 | < Tarinaky> | Helpful! |
| 16:58 | < Tarinaky> | Stupid bug is stupid. It fails if a directory doesn't exist :/ Lame. |
| 16:58 | < Tarinaky> | I'll deal with that later >.> |

| 21:43 | < RichyB> | Anyone know anything about getting vsync to work with OpenGL? |
| 21:43 | < RichyB> | I'm using GLFW on Linux with the ATI driver |
| 21:43 | < RichyB> | believe that I'm calling glfwSwapInterval(1) correctly |
| 21:44 | < RichyB> | but glfwSwapBuffers() just refuses to take 16ms. :/ |
| 21:51 | <@TheWatcher> | You're sure that it hasn't been forced off in the driver config? |
| 21:55 | <@TheWatcher> | "Notes: This function will only have an effect on hardware and drivers that support user selection of the swap interval. ATI drivers in particular have been known to ignore this setting." - the GLFW ref manual |
| 21:56 | <@TheWatcher> | (docs for glfwSwapInterval()) |
| 21:57 | <@TheWatcher> | Might be worth using it as you are anyway, forcing vsync on in the driver, and getting others to test it later. |
| 22:03 | < RichyB> | BRB, restarting X11 |

| 22:14 | < RichyB> | aticonfig --vs on, did nothing. |
| 22:15 | < RichyB> | amdcccle, 3d options -> force vsync, nope. |
| 22:15 | < RichyB> | swapbuffers() is still taking too few milliseconds. |
| 22:15 | < RichyB> | Feh. |
| 22:16 | < RichyB> | Tried switching from the compositing window manager to a non-compositing one, doesn't seem to have helped |
| 22:17 | < RichyB> | Next line of inquiry: installing OpenArena since that's known to be quake3, see whether any existing videogames have the ability to set vsync. |
| 22:28 | < RichyB> | dammit |
| 22:29 | < RichyB> | First answer is, a) openarena doesn't even have an option for vsync, b) who cares the bots can kick my arse anyway? :P |
| 22:31 | < RichyB> | Tried yanking the second monitor out and restarting X11, still not playing ball. |
| 22:43 | < RichyB> | Nope, Sauerbraten's vsync options don't work either. |
| 22:43 | < RichyB> | Saunerbraten actually *has* a vsync option, and it just doesn't work. |
| 22:43 | < RichyB> | Oh well! At least I know it's the driver, not me. |
| 22:47 | <&McMartin> | Don't rely on swapbuffers() for timing purposes, use micro- or nanosleep |
| 22:47 | <~Vornicus> | yeah, I learned that the hard way - you only get timing right off that when you are fullscreen /and/ have vsync |
| 22:49 | <&ToxicFrog> | Side note: even if vsync is on in both the software and the driver, it may not work in windowed mode at all |
| 22:49 | <~Vornicus> | right. |
| 22:50 | | Nemu [NeophoxProd@Nightstar-bece4b0d.asahi-net.or.jp] has joined #code |
| 22:50 | < RichyB> | Not what I'm aiming for! |
| 22:51 | < RichyB> | I know to use clock_gettime(CLOCK_MONOTONIC, ...); for timing. |
| 22:51 | < RichyB> | For starters, some people have 50Hz, 60Hz, 85Hz, 100Hz and even 120Hz displays. |
| 22:52 | < RichyB> | *CLOCK_MONOTONIC for simulation timing. |
| 22:53 | < RichyB> | I just want to kill tearing artifacts, and write videogames that let the transistors have a nap (and hopefully reduce power consumption a tad) when the scene being drawn is really cheap. |
| 22:54 | < RichyB> | Also I'm using a GC'd language and I want to try things like invoking small collections during the vsync waits to minimise the probability that GC kicks in and makes me drop a frame. |
| 22:56 | <&ToxicFrog> | Well, if it's on in the driver, and you're testing it fullscreen, I have no idea |
| 22:56 | <&ToxicFrog> | The drive might just be fundamentally broken |
| 23:00 | < RichyB> | I strongly suspect that that's the case. |
