Clojure equivalent of python's base64 encode and decode -


this question has answer here:

i have python code snippet , need clojure equivalent.

user_id = row.get('user_id') if user_id:     user_id_bytes = base64.urlsafe_b64decode(user_id)     creation_timestamp = int.from_bytes(user_id_bytes[:4],                                     byteorder='big')     dc_id = int.from_bytes(user_id_bytes[4:5], byteorder='big') & 31     if creation_timestamp > when_we_set_up_dc_ids:         row['dc_id'] = dc_id}

you can use clojure's java compatibility leverage java.util.base64 class.

user> (import java.util.base64) java.util.base64  user> ;; encode message      (let [message "hello world!"            message-bytes (.getbytes message)             encoder (base64/geturlencoder)]        (.encodetostring encoder message-bytes))  "sgvsbg8gv29ybgqh"  user> ;; decode message       (let [encoded-message "sgvsbg8gv29ybgqh"             decoder (base64/geturldecoder)]         (string. (.decode decoder encoded-message))) "hello world!"

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
