| stinebd | i feel so bad for gumby | 13:29 |
| arrrghhh | what did gumby do? | 13:30 |
| arrrghhh | In 2011, a man in a Gumby suit attempted to rob a 7-Eleven in San Diego | 13:31 |
| arrrghhh | lol is that what you're referring to? cuz that's awesome. | 13:31 |
| stinebd | he's so desperate to get high that he's robbing convenience stores | 13:31 |
| arrrghhh | lmao | 13:31 |
| arrrghhh | gumby had an accomplice. | 13:31 |
| stinebd | that guy wasn't with him | 13:32 |
| stinebd | you can tell who goes with gumby because they're single-color masses of clay | 13:32 |
| arrrghhh | epic | 13:32 |
| arrrghhh | lol | 13:32 |
| *** GlemSom has quit IRC | 14:20 | |
| jonpry | Detule, i'm actually not that far. its against bionic? | 14:21 |
| *** Kraln- has quit IRC | 14:22 | |
| *** Kraln has joined #xdandroid | 14:23 | |
| Detule | jonpry: yeah it's against xdandroid not sure if that makes a difference | 14:32 |
| Detule | jonpry: it runs on my phone, i was about to write a piece of code to do the gaussian fit | 14:33 |
| jonpry | xdandroid is fine for getting the code working. in the future we will need to make sure it is building for fpu | 14:34 |
| jonpry | probably a little bit slow on msm7k | 14:35 |
| Detule | i ran some simple optimizing code it was fine | 14:35 |
| *** rpierce99 has quit IRC | 14:35 | |
| jonpry | need real data? | 14:35 |
| *** rpierce99 has joined #xdandroid | 14:36 | |
| Detule | yeah a 3x3 would be nice | 14:36 |
| Detule | i'll send you the library and the demo binary | 14:37 |
| Detule | sent | 14:38 |
| jonpry | thanks. gf took the touchpad so no android device atm | 14:39 |
| rpierce99 | jonpry: did you ever end up unbricking? | 14:42 |
| jonpry | nah | 14:42 |
| jonpry | got another one | 14:42 |
| *** helicAWAY is now known as helicopter88 | 14:43 | |
| jonpry | Detule, the infamous pastebin will read the raw matrix. i have some binaries that can work under webos with some coaxing | 14:46 |
| jonpry | other people are grabbing dumps now though | 14:47 |
| Detule | oh it's ok i just want 9 data points to see if this will spit out a reasonable answer | 14:53 |
| Detule | i guess i can do it myself | 14:53 |
| jonpry | i just ran it on the prypad | 14:54 |
| jonpry | 212 iterations. some kind of result | 14:54 |
| Detule | right, it does some sample optimizing problem | 14:58 |
| Detule | you can see the code in lmdemo.c | 14:58 |
| Detule | it has a collection of problems and it's currently calculating one of them, Meyer's reformulated blah blah whatever that is | 14:59 |
| jonpry | interesting. are they doing numerical derivatives? | 15:00 |
| Detule | they have the option for both | 15:00 |
| Detule | i think in that particular problem they are doing numerical | 15:00 |
| jonpry | masses of data in your email | 15:02 |
| jonpry | here is a 3x3: 0A 18 05\n 0C 1A 04\n 04 06 00 | 15:04 |
| jonpry | pretty sure that for most of these the center should end up being within .5 units of the center of the matrix | 15:18 |
| Detule | i can assume this matrix is centered around zero then | 15:18 |
| jonpry | matrices from the edge or center will have more extreme values though | 15:18 |
| jonpry | sure | 15:18 |
| jonpry | er edge or corner | 15:19 |
| Detule | jonpry: what do you think are good initial values for amplitude, and standard deviation | 15:33 |
| Detule | oh i guess i'll try amplitude 30 std deviation 5 | 15:33 |
| jonpry | amplitude should be the peak value | 15:34 |
| jonpry | std deviation is ~1 | 15:35 |
| Detule | right putting those hex values in decimal i think peak value of 30 is not unreasonable starting point | 15:35 |
| mgross029 | arrrghhh, Just started out with a fresh 4K block size data.img... ran SC script from terminal... Enable SD-Booster with 8192 cache... pm disable... Rebooted and this thing is flying... | 15:36 |
| jonpry | i think it would be ok to preprocess the stuff. so use the actual mean as the guess for the center, and real peak value, etc | 15:37 |
| jonpry | for now probably overkill | 15:38 |
| *** virsys has quit IRC | 15:44 | |
| mgross029 | arrrghhh, Had to do the app installs manually since the tb versions weren't working... I did a data only restore though which brought back most of my settings for the apps... So not too bad | 15:48 |
| arrrghhh | cool | 15:49 |
| arrrghhh | oy why does everything happen on Friday's | 15:49 |
| arrrghhh | IRC is hoppin, and i am just freakin slammed today at work. | 15:49 |
| mgross029 | Yeah... I have a ton of work to do, but been messing with this phone all day... :D | 15:50 |
| mgross029 | I've showed this thing to a guy with a moto droid 1 and he couldn't believe how fast it was compared to his... He is trying to get it rooted now... lol | 15:51 |
| mgross029 | stinebd, how is the flooding? My oldest daughter said she was flooded out too... She's in Lancaster area... | 15:59 |

| Detule | jonpry | 17:14 |
| jonpry | yo | 17:14 |
| Detule | let me send you a binary you have that touchpad handy | 17:14 |
| jonpry | i got the tp back yes | 17:14 |
| Detule | sent | 17:15 |
| Detule | i haven't tested this so i have no idea what it'll do | 17:15 |
| jonpry | what is it? | 17:16 |
| Detule | but ideally it'll spew out a bunch of "Parameters are:" followed by 4 doubles, the 2nd and 3rd being the (x,y)-coordinates of the mean associated with those 9 measurements | 17:16 |
| Detule | each line is an itteration | 17:17 |
| Detule | ideally those numbers should converge | 17:17 |
| jonpry | so its not using the uart or anything that would require actual touchpad? | 17:18 |
| Detule | no the 9 values are hard coded -> it's pretty stupid | 17:18 |
| jonpry | does not seem to be converging very well | 17:19 |
| jonpry | http://pastebin.com/pb1HDguD | 17:20 |
| Detule | uh, i should perhaps use the analytic jacobian instead of the numerics | 17:21 |
| jonpry | that is usually better. but this seems strange. i wonder why it has so much trouble | 17:24 |
| jonpry | i'm not sure that we actually need to solve for the SD | 17:24 |
| Detule | k i am out, jonpry it's probably not converging well because chances are my algorithm is wrong, phone is dead so i can't debug anything...i'll write it with an analytic jacobian probably tomorrow | 17:44 |
| jonpry | k, thanks. cya | 17:46 |
