| 18:08 | < ktemkin[awol]> | Derakon_: There's an environment variable that you can use to skip buffering. |
| 18:09 | < ktemkin[awol]> | You can also just replace std.stdout with an unbuffered stream on start-up. |

| 20:23 | < Derakon_> | So. One of the devices in our microscope is a motorized sample positioner. |
| 20:24 | < Derakon_> | It ships with a joystick that you can plug into the device controller, but we do all of our positioning through custom software. |
| 20:24 | < Derakon_> | We'd like to be able to use the joystick, but only by routing it through our custom software. |
| 20:24 | < Derakon_> | (So we can enforce positioning safeties, speed limits, and the like) |
| 20:25 | < Derakon_> | The vendor's support has no idea how the joystick works, but it plugs in with standard USB. |
| 20:25 | < Derakon_> | Is there a standard joystick protocol so I can just read/write characters over a COM port, or what? |
| 20:25 | < Derakon_> | What's the best way to do this, given our software's all in Python? |
| 20:26 | <&McMartin> | Is it a joystick that shows up under Windows's Game Controller? |
| 20:26 | <&McMartin> | If so, I'd give pygame a shot. |
| 20:26 | < Derakon_> | Mmm...wouldn't pygame of necessity create its own window and the like? |
| 20:26 | <&McMartin> | On UNIX, the information lives in /dev/js* |
| 20:27 | < Derakon_> | I have yet to try actually plugging the joystick into the computer~ |
| 20:27 | <&McMartin> | I don't believe you have to call SDL_CreateVideoSurface ever, or indeed, pass SDL_INIT_VIDEO to SDL_Init. |
| 20:27 | < Derakon_> | Ah. |
| 20:28 | <&McMartin> | On Linux, /dev/js0 is a character device with a protocol I don't know |
| 20:28 | <&McMartin> | On Windows, DirectInput and XInput are the two protocols. |
| 20:28 | <&McMartin> | (SDL, and thus pygame, wrap DirectInput) |
| 20:29 | < Derakon_> | Thanks for the info. |
| 20:30 | < Derakon_> | pygame may well be the way to go here, since I expect joysticks probably won't have a very clean protocol that would be easy to reimplement. |
| 20:32 | <&McMartin> | StackOverflow and friends aren't showing anything immediately useful on my searches for going around it. |
| 20:32 | | * Derakon_ nods. |
| 20:32 | <&McMartin> | I'm sure it's possible, but it's probably a huge pain and I bet it also involves The Wrong Kind Of COM. |
| 20:33 | < Derakon_> | Hand-massaged binary, IOW? |
| 20:33 | <&McMartin> | No, Windows Component Object Model |
| 20:33 | <&McMartin> | (Their vaguely horrifying RPC/Object Broker mechanism) |
| 20:33 | < Derakon_> | I'm not familiar with it. |
| 20:33 | < Derakon_> | Sounds like that's a good thing. |
| 20:34 | <&McMartin> | IIRC It's a cross between what used to be Object Linking and Embedding and what used to be ActiveX. |
| 20:35 | <&McMartin> | Its "true interface" is like an RPC API of a C++ ABI, which I strongly suspect is exactly what it was originally |
| 20:35 | <&McMartin> | I'm told .NET wraps it sanely but if so it's the first thing to do so |
| 20:35 | < Derakon_> | Heh. |
| 20:35 | <&McMartin> | (In that you do something to say "get me an object of type X from the environment" and then you get back an object that you can just invoke methods on) |
| 20:37 | <&ToxicFrog> | Python question. |
| 20:38 | <&ToxicFrog> | How do I declare a method with a default value for an argument where the default value is the value of a field in the method's containing class? |
| 20:38 | <&ToxicFrog> | E.g. |
| 20:38 | <&ToxicFrog> | class Bar(Foo |
| 20:38 | < Derakon_> | You can't. |
| 20:38 | < Derakon_> | Use None as the default, then check for it at the start of the function. |
| 20:38 | <&ToxicFrog> | class Bar(Foo): field = 1; def waffles(self, thing=self.field): pass |
| 20:38 | <&ToxicFrog> | Blargh |
| 20:38 | <&ToxicFrog> | None is boolean false, right? |
| 20:39 | < Derakon_> | If evaluated as a boolean, it is False. |
| 20:39 | < Derakon_> | But it's the nil-type equivalent. |
| 20:39 | < Derakon_> | Or NULL, or whatever. |
| 20:40 | | * iospace blinks at this email |
| 20:40 | <@iospace> | wait |
| 20:40 | <@iospace> | we have a windtunnel? |
| 20:46 | <&ToxicFrog> | Derakon_: right, that's what I mean - it's not False but if evaluated as a boolean it is eqv to False |
| 20:47 | < Derakon_> | Yes. |
| 20:47 | < Derakon_> | I thought you mean '"None is False" evaluates to True'~ |
| 20:48 | <&ToxicFrog> | In that case I would have phrased it "None is False", not "None is boolean false"~ |

| 21:49 | | * Derakon_ blarghs. |
| 21:49 | < Derakon_> | Our microscopes have multiple cameras, which can be used to view different wavelengths of light. |
| 21:49 | < Derakon_> | Currently each camera's output is displayed as a grayscale image in its own separate canvas. |
| 21:49 | < Derakon_> | And I've gone to great lengths to make an efficient monocolor image display system that can handle rapid data streams. |
| 21:50 | < Derakon_> | Now they want an overlaid, colorized view. Which means multiple images per display. Which completely horks up my system. >.< |

| 23:40 | < Serah> | Back when last I checked Win8 was still inferior to Win7 for compatability and gaming. I'm getting a new box next month so I'm eager to know if this has changed. |
| 23:40 | < Serah> | TL;DR: Is win8 wothwhile? |

| 23:51 | <@froztbyte> | no :/ |
| 23:51 | <@froztbyte> | well, do you like being angered all the time? |
| 23:52 | <@froztbyte> | if you don't, probably just try to get your hands on a copy on win7 |
| 23:52 | < Serah> | I'll be buying a new OS, so I have free choice. |
| 23:52 | <@froztbyte> | I don't know if you can actually buy win7 easily |
| 23:53 | <@froztbyte> | in .za it's quite tricky |
| 23:53 | < Serah> | I can. |
| 23:53 | <@TheWatcher> | Do so |
| 23:53 | < Serah> | Fair enough. |
| 23:54 | <@TheWatcher> | There's no compelling reason to get Win 8, unless you're into pain or dislike your hair. |
| 23:55 | < Serah> | I am mostly concerned of discontinuation of drivers and other stuff. I expect to have this box for at least 3 years, aiming more towards 5 if possible. |
| 23:58 | <@TheWatcher> | Win 7 and 8 use the same driver model - if you can get a win 8 driver, provided the manufacturer isn't a dick, it'll work in 7 |
| 23:59 | < Serah> | Almost the same driver model. Win8 won't accept disguised vista drivers. |
| 23:59 | < Serah> | Although I suppose I'm probably better off that way. |
