mobile - How to identify device uniquely? -


firstly, know duplicates. we're not talking ios/android/kindofdevice-only, others & cookies not way want go.

so want bypass need of password or "binding" my service (which idea now) device used. e-mail , stuff needed of course, keep devices bundled.

what approaches be?

my thoughts far

  • my first idea using mac-adress, because heard they're unique. quick google told me that's not true.
  • on phones use phone number or imei, don't want restricted phones, should usable web, too.
  • i guess when talk web-solution, stuff more tricky because browsers won't let service go deep system , stuff?
  • of course guess there needs combination of 2 or more things. 2 not-so-unique things combine 99%-unique-thing?

i need how go on problem, direction, because if google terms "unique device identification" medicine-thing..

in project use

var secureudid = (uidevice.current.identifierforvendor?.uuidstring)!

which - returns string created uuid, such “e621e1f8-c36c-495a-93fc-0c247a3e6e5f”. uuid - alphanumeric string uniquely identifies device app’s vendor.

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
