.net - How to disable PLINQ partitioning/batching -


plinq internally batches items takes in order reduce overhead. since items memory intensive i'd minimize buffering exists in plinq query pipeline. how can disable partitioning/batching entirely?

the code looks this:

var myitems = enumerable.range(0, 10000000).select(_ => new byte[1 << 30]); var results =  myitems  .asparallel()  .withmaxdegreeofparallelism(4)  .select(f)  .tolist();

in code i'd expect maximum number of (big) items ineligible garbage collection 4.

what want create paritioner on source, specifies nobuffering, , use in plinq query:

var myitems = enumerable.range(0, 1000).select(_ => new byte[1 << 30]); var mypartitioner = partitioner.create(myitems, enumerablepartitioneroptions.nobuffering); var results =     mypartitioner     .asparallel()     .withdegreeofparallelism(4)     .select(f)     .tolist();

this query works me, throws outofmemoryexception if skip partitioner (just original query).

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

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
