i high school student interested in theatre programming. attempting make app our theatre ipad connect our lighting console. ipad has app want bare minimum. trying make faceplate panel in app. familiar objective-c not sure how connect , control console on ip address app console manufactures does. how go doing this? example code? tutorials? thanks, thomas so bigger answer , more of general rule of thumb guide rather concrete solution. to connect device on ip, same connecting via internet, has discoverable, , have ports open. if can find both of things, better hope has api! if device has no api, shit out of luck unless want hack (which cannot do, thats how security works @ level tinkering at). so, if there api, consume it. here links apis/ rest http://www.restapitutorial.com/lessons/whatisrest.html http://en.wikipedia.org/wiki/representational_state_transfer http://www.webopedia.com/term/a/api.html if have api, use required get/post/put/patch/delete etc http c...

when set style on html tag, in angularjs: angular.element($document[0].documentelement).css('overflow', 'hidden'); the page jumps top of page. how can prevent this? i trying display full page overlay, , when try scroll, background scrolls. doesn't scroll when set overflow: css style on html tag. has lead me problem. when hide document, you're telling browser not scroll. that's why you're being directed top of page, page in essence no longer extends beyond viewport. while not every browser send top of page (expected behavior here lock user page they're at), active tracking of hash (e.g. mypage.com/#showlogin/) angular uses routing cause page jump top of screen. edit: if want keep background doesn't scroll page, use property background-attachment : html, body { ... /* other code here */ background-attachment: fixed; }

i developing program recursively generates frequencies of tones in scale. each frequency twelfth root of 2 higher previous one. program must use recursion (ugh, education). when use method, initial tone repeated on , on , on again. why that? public static void scale(double x, double z){ double y; if(z == x){ y = z * math.pow(2, (1/12)); system.out.println(y); scale (y, y); } else if(z >= (2 * x) - 1 || z <= (2 * x) + 1){ y = z; system.out.println(); } else{ y = z * math.pow(2, (1/12)); scale (y, y); } system.out.println(y); } why that? because of java's integer division. specifically, 1/12 becomes 0 , not 0.083333333 , because int must yielded. 2 raised power 0 1 , y same z . use double literals force floating-point division. 1.0/12.0
