How to run multiple bash scripts from python master script in parallel? -


i have series of time consuming independent bash scripts run in parallel on 7 cpu cores python master script. tried implement using multiprocessing.pool.map() function iterating on numbers xrange(1, 300) sequence, every number used define name of directory containing bash script executed. issue following script spawns 7 processes bash script runs , finishes right after completed. 

import multiprocessing import os a= os.getcwd() #gets current path def run(x):             b = + '/' + 'dir%r' % (x) # appends name of targeted folder path             os.chdir(b) #switches targeted directory             os.system('chmod +x run.sh')             os.system('./run.sh') # runs time consuming script if __name__ == "__main__":     procs = 7     p = multiprocessing.pool(procs)     p.map(run, xrange(1, 300))     print "====done===="

i expect other 292 shell scripts run well, fix or alternative implementation me? thank you!

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
