| 04:15 | <@ToxicFrog> | Woot. Map loading interface is done. |
| 04:15 | <@ToxicFrog> | Apart from the bit where clicking on a map to load it doesn't actually load the map because I haven't written that part of the model~ |
| 04:16 | <@Derakon> | Ahh, that's UI. It can wait. |
| 04:24 | <@Derakon> | Curses. My attempt to use boolean logic in a .bml file is foiled by my dependence on '<' which is a special character in XML. |
| 04:44 | | * Derakon adds support for multiple colors of bullets. |
| 04:45 | <@Derakon> | Ideally this would be through pallet swapping, but the bullet graphics are not terribly large and it's easy to add new colors. |
| 04:50 | <@ToxicFrog> | Derakon: well, no, the bit I just finished is UI, the bit I haven't implemented is backend~ |
| 04:50 | <@ToxicFrog> | Because I'm doing this part top-down so I can figure out what the API for map management should be. |
| 04:50 | <@Derakon> | Ah hah. |
| 05:04 | | * Derakon creates a fireworks bullet pattern. |
| 05:05 | <@Derakon> | Unfortunately, it has a massive hole along the bottom edge of the screen, so I added some random-fire shotguns to cover those areas and force the player up to where the fireworks are going off. |
| 05:05 | <@Derakon> | Feels like a hack. :\ |
| 05:49 | <@Derakon> | Why would evaluating 360/(int(0.02)*6.0) give an error "float division"? |
| 05:49 | <@Derakon> | ...because I'm an idiot. |
| 05:52 | <@ToxicFrog> | ... |
| 05:52 | <@ToxicFrog> | Yeah, doesn't that turn into 360/0? |
| 05:52 | <@Derakon> | Yes. |
| 05:52 | <@Derakon> | I was reading it as int(.02*6.0), which has similar problems but is less obvious. |

| 06:13 | <@Derakon> | I am a GEEEEENIOUS. |
| 06:14 | <@Derakon> | I've created a bullet pattern where the emitter starts by laying out a circle of bullets which hang in space. Each bullet then periodically fires a shotgun at the player. |
| 06:14 | <@Derakon> | The circle has a fixed radius, but the number of bullets in it increases as you rank up (so more shotguns fired). |
| 06:14 | <@Derakon> | I call it "doomcircle", as even at rank 0 it's pretty hard. |
| 06:16 | < ASCII> | do they fire simultaneously or in sequence? |
| 06:16 | <@Derakon> | In sequence. |
| 06:16 | <@Derakon> | I could make them fire simultaneously with some cleverness in their wait patterns...but such patterns tend to be easier to game. |
| 06:31 | <@Derakon> | http://derakon.dyndns.org/~chriswei/temp/bulletmlscreen5.png |
| 06:42 | < ASCII> | and that's with 1x1 hitboxes for everything, or just the player? |
| 06:43 | <@Derakon> | Bullets use radius-15 balls (it occurs to me that should be 10). The player is a pixel. |
| 06:56 | < ASCII> | the ship rotates, or just moved in directions? |
| 06:57 | <@Derakon> | Just moves in directions. |
| 06:57 | <@Derakon> | Inertial ships and manic shooters do not mix well. |
| 07:25 | | * ToxicFrog strangles windows |
| 07:25 | | * Vornicus helps more. |
| 07:26 | <@ToxicFrog> | So, someone's written a kernel module for the PSP that can output the video over USB, and read control input in the same way. |
| 07:26 | <@ToxicFrog> | Which means you can plug it into the computer when at home and then, say, play it fullscreen on your 22" LCD monitor using a PS2 controller. |
| 07:27 | <@ToxicFrog> | Eeeeeeexcept...Durandal refuses to recognize any of its USB ports as USB2. |
| 07:27 | <@ToxicFrog> | I invite you to guess how well realtime video streaming works over USB1. |
| 07:27 | | * Derakon snerks. |
| 07:28 | <@Vornicus> | Heh. |
| 07:30 | <@ToxicFrog> | Arlghfsaksagasg |
| 07:30 | <@ToxicFrog> | There is source available, but it's windows-only |
| 07:30 | < ASCII> | I can take a wild stab in the dark and say that it gives realtime a new meaning |
| 07:30 | <@ToxicFrog> | I wonder how much work it would take to port it to SDL. |
| 07:30 | <@ToxicFrog> | Or peel the frontend off the (old, notoriously unstable) PSPLink based SDL build and affix it to 0.19. |

| 22:01 | <@Consul> | http://link.brightcove.com/services/player/bcpid1813626064?bctid=6738580001 -- Guitar Hero-like game with a real guitar. |
| 22:02 | <@Consul> | Most of it is stupid vendor trade show ass-kissing, but at least you get to see the game in action. |
| 22:10 | <@Consul> | I love how he said that new patented technologies were required. MIDI pickups have been around for about 20 years now. |
| 22:10 | <@Derakon> | Probably talking about the software. |
| 22:10 | <@Finerty> | mmm, midi pickups. |
| 22:10 | <@Derakon> | Though I'm sure they'll sell gold-plated hookups for the audiophiles. |
| 22:11 | <@Consul> | Derakon: I don't know. I'm sure, like most supposedly new tech these days, the patents are either general or obvious. |
| 22:13 | <@Consul> | Hell, I've been kicking around ideas with others on using FFT to detect the roots of the harmonics present in an electric guitar signal. No MIDI pickup required. |
| 22:13 | <@Consul> | Doing it in real time, that's the trick. |
| 22:13 | <@Derakon> | That's why it's called the fast Fourier transform~ |
| 22:14 | <@Consul> | Well, there's doing the FFT, and then there's extracting the information you need out of it. |
| 22:16 | <@Consul> | Sure, you can pick out the six strongest partials, but you're also assuming six strings are struck. |
| 22:17 | <@McMartin> | Harmonics can likely burn the Hell out of you |
| 22:17 | <@McMartin> | Especially if they reinforce. |
| 22:18 | <@Consul> | The Melodyne guys figured out a way to make it work. |
| 22:18 | <@McMartin> | If you're going for top six or whatever that may make it easier |
| 22:19 | <@Consul> | They can analyze a signal and pick the individual notes out of a chord, with amazing accuracy. And then to top it all off, you can manipulate single notes inside of a signal containing a chord. |
| 22:19 | <@McMartin> | My own experiments long ago were with single notes from a *piano*, which probably has a different sound envelope |
| 22:19 | <@Finerty> | Pianos are pretty damn hard. |
| 22:20 | <@McMartin> | But yeah, I'd frequently have notes extracted that corresponded to no actual key. |
| 22:20 | <@Consul> | If you have a specific instrument, you have the benefit of knowing in advance with the harmonic structure of a single note should look like. |
| 22:20 | <@McMartin> | Yeah, and if the elec-guitar's is unusually simple, that would make life easier |
| 22:20 | <@McMartin> | The changing-one-note-in-a-chord thing sounds like it would follow immediately from having that information, too. |
| 22:21 | <@McMartin> | That's what makes working in the frequency domain so awesome in the first place. |
| 22:21 | | Attilla [~The.Attil@Nightstar-9469.cdif.cable.ntl.com] has quit [Ping Timeout] |
| 22:22 | <@Consul> | You could work from the top of the range down. |
| 22:22 | <@Consul> | Start at 20khz, take the first peak, assume it's a harmonic... |
| 22:22 | <@Consul> | Actually, no... |
| 22:22 | <@Consul> | Start at the bottom, and assume the first peak is a root not. |
| 22:22 | <@Consul> | note* |
| 22:23 | <@Consul> | Work up from there. |
| 22:23 | <@Consul> | Is the next peak a harmonic or not of the first peak? If not, it's a new root note. |
| 22:23 | <@Consul> | Then the confusion becomes, with if a root note were struck that corresponds exactly to a harmonic of a known root? |
| 22:24 | <@Consul> | s/with/what |
| 22:24 | <@Consul> | That's when you start looking at relative strengths of the harmonics. |
| 22:25 | <@Consul> | Also, for equally-tempered instruments, the only notes corresponding to natural harmonics are octaves. |
| 22:26 | <@Consul> | This is the part of the process where knowing what instrument you're dealing with can help. |

| 22:26 | | mode/#code [+o Attilla] by ChanServ |
| 22:27 | <@Consul> | And you still can't solve the problem of "what if a higher note corresponding to a harmonic of a lower note was struck with a lower amplitude?" |
| 22:28 | <@Consul> | Suddenly, a custom pickup on the guitar starts to seem reasonable. :-) |

| 22:42 | <@Consul> | Still, if the goal were a little app that could turn a guitar input into control signals for a softsynth, you might be able to get 90% of the way there and tell the player to play more carefully to get that last 10%. :-) |
| 23:08 | <@Finerty> | Compute!'s Gazette! |
| 23:09 | <@Consul> | I used to subscribe to that mag. |
| 23:09 | <@Finerty> | Also, the FF "Awesome Bar" takes a bit of getting used to but it seems nicer than just plain URL filtering |
| 23:12 | <@Consul> | Stupid YouTube comment #1,512,478: "It's electronic music, not electronica. There's a difference. Electronica is made on computers, electronic is pre- computer and sometimes even pre-synthesizer, like most of Delia's music." |
| 23:13 | <@Finerty> | surely there's more than that many SYTCs |
| 23:15 | <@Consul> | All of them. |
| 23:15 | <@ToxicFrog> | "awesome bar"? |
| 23:16 | <@Consul> | What's the limit of intelligence as number of YouTube comments goes to infinity? |
| 23:17 | <@McMartin> | TF: The history dropdown while you're typing a URL. |
| 23:17 | <@ToxicFrog> | ...that's it? |
| 23:17 | <@McMartin> | In particular the fact that it's more than tab completion, which is what makes it awesome/an abomination unto the world/different. |
| 23:19 | <@Finerty> | THe 'awesome bar' matches not only URL roots from the HIstory (as Safari does), but arbitrary sections of the URL and title. |
| 23:19 | <@McMartin> | Which is unnervingly frequently presented as it providing "the wrong answer" |
| 23:19 | <@McMartin> | Which I can only make make sense if they ignore bookmarks/keeping tabs open entirely and do all their browsing by reflex, hitting, say, www.cn*down**enter* without looking at the screen |
| 23:20 | <@Finerty> | So on Safari, to get goodmath as opposed to denialism (scienceblogs.com/goodmath and scienceblogs.com/denialism, respectively), I have to go sci and then several down things while looking to get to the right one. |
| 23:21 | <@Finerty> | In Firefox it's "good" and "de" and then one down/enter. |
| 23:22 | <@ToxicFrog> | Right. |
| 23:23 | <@ToxicFrog> | Opera has the same feature, just not under that name. |
| 23:26 | <@Derakon> | You can think of the awesomebar as basically being a search for your URL history. |
| 23:41 | <@Consul> | I keep envisioning a candy bar or energy bar or some such. |
| 23:41 | <@Consul> | Get through the day with a protein power of AwesomeBar! |

| 23:53 | <@Consul> | Heh |
| 23:54 | <@Consul> | I found a can of Dickens Cider at a convenience store in a town called (I think) Bella Vista in Colorado. |
| 23:59 | <@Consul> | And I seem to recall a pub in England having the name "The Cock 'n' Cider." |
| 23:59 | <@Consul> | I don't know how long that one lasted. |
