i new area - have background in gait , posture. i have series of motion files of timestamped coordinates (containing x, y, , z in mm) number of joints (30). what simplest way extract following motion observations. 1) number of active features (i.e. active joints). 2) average speed of motion. same file format of nxp. p number of joints , n number of frame observations. what looking pointers possible areas explore. regards, dan a couple of possibilities might explore - both using free , (and open source), software : python + numpy / scipy can read in coordinate values , calculate data require - possible plot in 3d using matplotlib . you use positional data animate stick figure in blender - of test blends provide starting point this .

i'm looking way write unformatted data memory using c++ standard library. i'd class inherits istream/ostream , works ifstream/ofstream, backed memory instead of file on disk. this way can work istreams , ostreams , use operator<< , operator>> read/write binary data, , don't need know whether data streaming memory or onto disk. i thought perhaps istringstream/ostringstream configured write unformatted output via operator<< , operator>>, couldn't see simple way this. so wasn't able find in c++ standard library or in boost, seems sort of thing should there. advice appreciated! you can't use << , >> operators write/read unformatted data (they dealing textual input , output), can use write method of output streams , read method of input streams. and std::string don't care data holds should able use stringstream (and output/input variants).

so i've been playing android camera library , using in surfaceview. have found there's no way capture pictures match preview. in fact, 1 has check preview , picture sizes , set camera parameters best match possible. also, can't set camera have same sizes both since app crash if camera doesn't support them. how can be? there no other solution? mean instagram seems use (it doesn't launch phone's camera app) , there seems perfect match. any ideas? thanks! simplest, , largely practical, approach treat preview mere feedback mechanism , concentrate program logic on getting best - , desired - quality of image capture. there little novelty in mixing 2 together. also, desired image capture quality may depend on different factors/options. based on post capture processing times, storage constraints, upload constraints, , more; best quality image may not desired one. implementation wise, camera apps follow common practices below: use camera.getpara...

i'm trying create macro application start running operations when key pressed (system wide shortcut). did created windows form application visual studio 2012. when form loaded keyboard hook installed: hookhandle = setwindowshookex( wh_keyboard_ll, (hookproc)keyboardhookhandler, getmodulehandle(null), null); if( hookhandle == 0){ messagebox::show("error setting hook!"); } my hook callback function is: public: static lresult callback keyboardhookhandler( int code, wparam wparam, lparam lparam ) { if(code>=0 && wparam == wm_keydown){ messagebox::show("key down"); } return callnexthookex( hookhandle, code, wparam, lparam); } when compile application , run message box never shown. more know call function fired wparam contains value 45 (i did checked , none of wm constants should returned has value 45). after few key events application crashes. what reason why code doesn't work should to? update: did removed cas...

i installed zsh package. so, when type zsh in terminal switches bash zsh. also, downloaded oh-my-zsh framework customize zsh. when change theme name in .zshrc file 1 of themes given here , changes color/type of prompt among other things background color stays same. want background color change ones given on theme wiki page. so, how do change background color automatically ones on page whenever change theme? changing background color should dependent on terminal emulator. this answers questions using setterm: change background color in gnome terminal through command? another link xterm: xterm: how change background color?

i'm trying work on ios app turns off screen (so when in dark, doesn't show light @ all), can turn on , off pixels of screen. does know way this? assuming it's either or nothing... either turn off screen, or turn on, maybe knows better? i guessing best turn background black little light possible comes through. however, tried using ipad , still generates light in pitch black room. want instance, 1 pixel shine brightly, , rest not glow @ all. , if not possible, there way mimic this? as far i'm aware screen either on or off, there's no controller setting specific regions on/off. also can't change pixel level brightness, screen isn't illuminated way. can control overall screen brightness, not each pixel, screen lighting technology doesn't work way, it's led backlight.

really curious below program (yes run in release mode without debugger attached), first loop assigns new object each element of array, , takes second run. so wondering part taking time--object creation or assignment. created second loop test time required create objects, , third loop test assignment time, , both run in few milliseconds. what's going on? static class program { const int count = 10000000; static void main() { var objects = new object[count]; var sw = new stopwatch(); sw.restart(); (var = 0; < count; i++) { objects[i] = new object(); } sw.stop(); console.writeline(sw.elapsedmilliseconds); // ~800 ms sw.restart(); object o = null; (var = 0; < count; i++) { o = new object(); } sw.stop(); console.writeline(sw.elapsedmilliseconds); // ~ 40 ms sw.restart(); (var = 0; < count; i++) ...

this question has answer here: java thread affinity 5 answers let's have server 4 processors. want implement cache served 4 threads. requirement - each thread should act on it's own processor? how can achieve this? you need set thread affinity each thread specify cpu want run on. there's examples on web on how it, there's nice github repository here sample code on how done. esentially, set each threads affinity different core.

i create , use rsa public/private key encrypt/decrypt message.i store them sharedpreferences string , when need them create string. works perfectly, secure store private key in sharedpreferences string. question : sharedpreferences mode_private security i learned that, can reach sharedpreferences , can generate private key string. can make private key secure while save on phone? it depends on the level of sensitivity of private/public key pair. think, storing them in sharedpreferences not bad idea. key pair stored relative app directory , has system protection external access. but, word "shared"preferences implied, key pair shared among app components. so, if need better protection, consider storing key pair in keystore class instead . of now, best solution key pair protection. provides password based key protection. update: there great article on android keystore , keychain usage here .
