| 00:54 | | * Derakon eyes a problem he fiddled with earlier today as a break from less frustrating work. http://pastebin.com/QfuN90pc |
| 00:55 | < Derakon> | The idea being to come up with a sensibly-scaling approach to HP/MP regeneration. |
| 00:55 | < Derakon> | You start with a base rate of getting 1 point per N turns. Each bonus point to your regen stat gives you an extra point of HP/MP in that N turns, smoothly distributed. |
| 00:55 | < Derakon> | The pasted code almost works, but breaks down e.g. with a base rate of 5 and a bonus of 9. |

| 01:04 | < Vornicus> | What, the way the thing goes 2111221112, which is not very smooth? |
| 01:04 | < Derakon> | Mm, I guess that's not as smooth as it could be either. But mostly I was referring to how you get 22 regen in 10 turns instead of 20, the way you're supposed to. |
| 01:04 | < Derakon> | Which I think is line 15's fault... |
| 01:05 | < Vornicus> | Oh, that's a bit different. |
| 01:05 | < Vornicus> | Um... |
| 01:05 | < Vornicus> | Do yourself a favor and avoid floating point math here like it's the devil, because it is. |
| 01:06 | < Derakon> | The only floating point involved is a single comparison. |
| 01:06 | < Derakon> | Between bonusRate and some math derived from turnNum. |
| 01:06 | < Derakon> | I just noticed, I have the variables bonusRate and rateBonus. My mind was not all there when I was writing this, clearly. |
| 01:07 | < Vornicus> | Heh |
| 01:07 | < McMartin> | Does python have built-in infinite-precision rationals? |
| 01:07 | < Vornicus> | I think there's one in the stdlib. |
| 01:07 | < McMartin> | That would count, yes |
| 01:07 | < Vornicus> | http://docs.python.org/library/fractions.html |
| 01:08 | < Derakon> | That would work, but this was written as an example on the Dungeons of Dredmor forums, and I've no idea what that's implemented in. |
| 01:14 | < Vornicus> | C, and if they have any chops at all they're also avoiding floating point and using more conventional methods. |
| 01:14 | < Vornicus> | or, rather, more, um... |
| 01:14 | < Vornicus> | SOmething. |
| 01:14 | < Derakon> | Ah, FAQ says C++. |
| 01:15 | < Derakon> | More consistent, perhaps? |

| 01:15 | < Derakon> | Whoops. |
| 01:16 | < Vornicus> | Anyway: points = 0; while True: points += (1 + bonus); regen, points = divmod(points, base); yield regen;; |
| 01:20 | < Derakon> | ...much nicer. |
| 01:20 | < Derakon> | Thanks. |
| 01:21 | < Vornicus> | Adding a dither so it's "smoother" in some sense is a little harder; you randomly add 1 to regen (and subtract base from points) based on the number of points remaining after the divmod. |
| 01:33 | < Vornicus> | (this will give a small positive bias in the first few but it goes away quickly) |

| 05:07 | < Vornicus> | hooray, emufun |
| 05:09 | | Kindamoody is now known as Kindamoody[zZz] |
| 05:09 | < McMartin> | "300 baud? The luxury! We had to tie notes to rats and birds. Eight rats and one tropical bird it was." |
| 05:09 | < ToxicFrog> | Fixes: selected game is now hilighted; sensible reaction when gamedir is missing or empty; attempting to bind multiple actions to the same key no longer crashes; broken symlinks and similar non-files are silently skipped. |
| 05:09 | < McMartin> | "That last was for parroty." |
| 05:10 | < ToxicFrog> | New features: support for .emufun files, node:add_command, and --!emufun pseudo-games; directories are rescanned when viewed rather than on startup; emufun can now be restarted internally. |
| 05:12 | < ToxicFrog> | Game hilighting should probably be a feature rather than a fix, but it's a fix to me~ |
| 05:13 | < ToxicFrog> | Anyways, upshot of all this: it's easier to use, it no longer needs keyboard intervention when something goes wrong (hopefully), and you no longer need to restart X to rescan directories. |
| 05:27 | < ToxicFrog> | I have to say, Emufun is neither the most interesting nor the most technically impressive of my projects, but it is by far the most useful. |
| 05:46 | < Derakon> | What is this, a manager for emulated games? |
| 05:48 | < ToxicFrog> | A frontend, actually. |
| 05:49 | < ToxicFrog> | It's basically an HTPC frontend with the ability to launch arbitrary programs with arbitrary configurations. |
| 05:49 | < ToxicFrog> | So you can, say, use it for movies and TV by creating a .config for your TV directory telling to launch those files with mplayer. |
| 05:50 | < ToxicFrog> | And use it for PSX games by telling it to launch those files with pcsx. |
| 05:50 | < ToxicFrog> | Etc. |
| 05:50 | < ToxicFrog> | Configuration files are just bash scripts, so you can get as complicated as you want with them and launch basically anything. |
| 05:51 | < Derakon> | Interesting. |
| 05:51 | < Derakon> | I could see that coming in handy if you used your TV a lot...mine is mostly for console gaming. ?.? |
| 05:51 | < ToxicFrog> | (the original use case here is "I have an old P4 that I want to play PSX/SNES/Genesis/DOS games on, but I also want to be able to drive it entirely with a gamepad") |
| 05:51 | | * Derakon nods. |
| 05:52 | < Derakon> | If I could fix the GPU fan in my old iMac I suppose I could repurpose it for a similar task. |
| 05:52 | < ToxicFrog> | Yeah, ditto here; but we had an old P4 and decided it would be nice to be able to play some older games from the couch as well. |
| 05:52 | < ToxicFrog> | Cue lots of "testing" with Wacky Wheels, Bio Menace, One Must Fall, Sonic 3, and Super Aleste~ |
| 05:53 | < Derakon> | Heh. |
| 05:53 | < ToxicFrog> | Since then, my old laptop with the bum hinge has also had emufun installed and been connected to Durandal's secondary monitor, so symbol can use it for gaming and TV-watching from the futonbed even if Durandal is otherwise in use. |
| 05:54 | < ToxicFrog> | (which was previously a problem; Durandal served both as my gaming desktop and as the bedroom media PC) |
| 05:56 | < ToxicFrog> | The upshot of this is that it's damn useful and sees pretty much daily use. |
| 05:56 | < Derakon> | Cool. |
| 05:56 | < Derakon> | As I said, if I can fix the GPU fan on the iMac... |
| 05:57 | < Derakon> | (And figure out how to hook it up to the TV...and install the floor what's going to be the TV room...) |
| 05:58 | < ToxicFrog> | Well, it's all on github~ |
| 05:58 | < Derakon> | Righto. |
| 05:58 | < ToxicFrog> | I've only ever tested it on linux, but it should work unmodified on OSX as well. |
| 05:58 | < ToxicFrog> | (or you could just install linux on the imac) |

| 21:25 | < gnolam> | Use an std::vector instead of an array, then use std::sort. |
| 21:26 | < McMartin> | That's the production answer. If this is a homework assignment, we generally aren't much help with those. |
| 21:26 | <@Tamber> | Pshaw, sleepsort ftw! >:| |
| 21:27 | < McMartin> | Which is to say, if they're trying to teach you how to do sorts, they'll be unimpressed with "I call a sort function that's in the library". |
| 21:27 | < McMartin> | That said, for the problem statement, you shouldn't do a sort to perform MAX or MIN. |
| 21:28 | < gnolam> | Well, we do help with homework as well. As long as it's along the line of "We've been told to implement quicksort, but I don't understand how to pick the pivot element - could you please help?" and not "We've been given these 3 assignments. Please solve them for me.". |

| 22:56 | < Derakon> | Instead of working I'm coming up with a design for a poi robot. |
| 22:57 | | * gnolam rarghs. |
| 22:57 | < gnolam> | I /know/ I have a resistor and capacitor set somewhere. I just don't know where they are. |
| 23:03 | < Derakon> | Man, I don't even know if it's possible to buy a three-DoF motor, let alone how to control it. |
| 23:10 | < gnolam> | It's called an industrial robot. :P |
| 23:13 | < Derakon> | Well, but I don't need to be able to push hundreds of pounds around. |
| 23:15 | < Derakon> | Anyway, seems like you should be able to simulate 3DOF with three linear motors in series. |
| 23:15 | < gnolam> | Buy a hobbyist pan/tilt servo kit and tack on an extra servo for the third axis? |
| 23:15 | < Derakon> | Yeah, that sounds like a good start. |
| 23:15 | < Derakon> | Basically I have no robotics knowledge at this level. |
| 23:16 | < Derakon> | My robotics course was more about image processing and mapping than it was about device control. |
| 23:16 | < Derakon> | (Because it was CompSci, not Engineering) |
| 23:18 | < Derakon> | ...motors are expensive. ._. |
| 23:19 | < Derakon> | Of course, a lot of what I'm seeing here is for cameras. |
| 23:22 | < gnolam> | All servos are PWM controlled, pretty much. |
| 23:25 | < Derakon> | Well, presumably this project would involve an Arduino, and they have motor-control modules, so I think I'd be abstracted away from %Bthat%B much detail anyway. |
| 23:25 | < Derakon> | Er, that. |
| 23:25 | < gnolam> | Note to self: 10 cd is apparently way too much for a warning LED. While the light is indeed very noticeable, temporarily blinding the operator does not feel like proper ergonomics. |
| 23:26 | <@Tamber> | XD |
| 23:26 | <@Tamber> | Possibly not, no. |
| 23:27 | < Derakon> | There's a ridiculously bright red LED in the microscope room. Very annoying to have that shining into your peripheral vision. |
| 23:31 | | * TheWatcher readsup |
| 23:31 | < TheWatcher> | Derakon: this sounds like an excellent excuse to get hold of a lego Mindstorms kit, and a load of technik parts~ |
| 23:32 | < Derakon> | I was assuming Arduino, actually. Any particular reason to go with Mindstorms instead? |
| 23:35 | < Derakon> | Also, it occurs to me that the project is basically "Make my own robotic arms", with a sub-goal of "make them perform poi techniques". |
| 23:35 | < gnolam> | An Arduino is just a blinged-up, more expensive AVR. And even the most lowly AVR has a PWM generator, so you shouldn't even need any additional modules. |
| 23:35 | < Derakon> | AVR = http://en.wikipedia.org/wiki/Atmel_AVR ? |
| 23:35 | < gnolam> | (Well, depending on how many motors you want to control, of course. An ATTiny only has one timer, for example.) |
| 23:35 | < TheWatcher> | Mostly I was not being serious. But I do know the guys in robotics in work use them pretty extensively, mostly for the fast build speed and flaxibility |
| 23:36 | < gnolam> | Yep. |
| 23:36 | < Derakon> | Yes, I can see how the ability to turn your robot into fiber could be important. *ducks* |

| 23:37 | < Derakon> | Gnolam: assuming that you want to do shoulder (3DOF) plus elbow (2DOF) plus wrist, that's 6 motors for one arm. |
| 23:39 | < Derakon> | ATTiny has 20 pins and 2KB of memory; if you use 8 bits for positioning then I could see using one ATTiny to control two motors -- 2x8 pins out for positioning, 4 pins in for which action to perform. |
| 23:40 | < Derakon> | I'm guessing the actual program here will simply be a lookup table of position with respect to time. |
| 23:42 | < Derakon> | Must go; will be back later. Meanwhile, http://derakon.livejournal.com/445856.html |

| 23:42 | < gnolam> | ... 20 pins for an ATTiny? That defeats the whole point of "tiny". :o |
