hash - Ruby and Chef difference in hashes -


i've been programming in ruby little while , have heard using symbols accessing values in hashes "better practice" using strings, e.g.

default[:key] = value    on  default['key'] = value

i've been working on chef project , noticed chef cookbooks use second way access hash values (via strings). accessing via symbol alternative not work!

so guess question 2 part, should stop using symbols , use string accessors everywhere? , why use of symbols not work?

t.l;d.r. accessing attributes symbol discouraged in favor of strings, despite still in use.

quoting lamont granquist chef in foodcritic (linter) issue here

chef implementation of mashes converts symbols internally strings

the official recommendation in docs use strings.

to complete overview of chef attributes can access them instance method, i.e. node.key.subkey method deprecated , removed in short mid term.

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
