i working on project requires circular ring shaped body. how can achieve this? have tried use convex-polygon body vertices similar of circle getting the vertices specified not match of _convex_ polygon. error. how else can make ring shape? here current attempt: var ring = physics.body('convex-polygon',{ x: renderer.width* 0.35, y: renderer.height *0.75, vertices : [ { x: -5, y: 0}, { x: -3, y: 4}, { x: -4, y: 3}, { x: 0, y: 5}, { x: 3, y: 4}, { x: 4, y: 3}, { x: 5, y: 0}, { x: 3, y: -4}, { x: 4, y: -3}, { x: 0, y: -5}, { x: -3, y: -4}, { x: -4, y: -3} ] }); thanks in advance! a ring shaped body not convex, reason model (assuming vertices correct) not work. this old answer seems suggest concave objects such yours not implemented in physicsjs. might have changed, if not want not possible. edit: link seems have been broken. fixed.

i have ios project, link binding library , correctly works without issues. when send xarchive customer (so xarchive signed him), app crashes @ launch seem miss during xarchive build? using external library maybe have check additional options in xamarin studio build tab? update: pluggin ipad , launching xcode devices windows, error is: runtime error: assembly mscorlib.dll not found or not loaded searching found this: https://developer.xamarin.com/guides/ios/troubleshooting/questions/error-mscorlib-not-found/ this issue occurs when hidden .monotouch-32 , .monotouch-64 folders missing .xcarchive signing / ipa creation, triggering runtime error. how can fix it? i confirm issue related https://developer.xamarin.com/guides/ios/troubleshooting/questions/error-mscorlib-not-found/ my archive uploaded owncloud company. owncloud client doesn't upload hidden files/folders (as .monotouch-32 , .monotouch-64 ), xarchive received customer different , smalle...

i'm reconstructing matlab based application web based. @ specific point (of matlab's implementation), user uploads set of data consisting of 2 columns (x, y) depicted dots using scatter plot. subsequently "best fitted" curve passes through points estimated , designed using matlab's build-in non-linear least squares function , trust-region optimization algorithm. is there way implement function either sql server or in .net code respectively? looking simple example understand algorithm (step-by-step) hard me find pseudocode or implementation in language concerning non-linear regression. have found solutions linear fitting in case specific algorithm work because have produce same results (as matlab's application does).

there odd error in application can't find workarounds/fixes for. reason, i'm able save address contact isn't unified social profile (facebook, twitter, etc). however, when try add address contact unified facebook or twitter weird save error: the operation couldn’t completed.

i have class @observable (all examples typescript/pseudocode) class page { id: number = 0; @observable isvisible: boolean = false; } let array = [new page(), new page(), new page()]; and functions like: changevisibility(obj) { //ajax call .post("/api/changevisibility/", {id:obj.id, isvisible:obj.isvisible}) } and want react on isvisible change on object. i can enumerate array , make like: array.foreach(el => { reaction( () => el.isvisible, isvis => changevisibility(el); }); }); but can 1 function? kind of "array observer reacts element's property change". something this: reaction(array, //source (el) => el.isvisible, //observable react (el) => changevisibility(el) //callback object ) if reaction responsible sending the update of individual page, setup reaction in page constructor or have utility function in page that, don't have keep pages array in sy...
