Generate random boxed co-ordinates in c# -


i need find random co-ordinates, bound square. defined values 70, 55, 175, 175 furthest points want go to:

north = utility.generaterandomnumber(utility.directions.north, 70); south = utility.generaterandomnumber(utility.directions.south, 55); east = utility.generaterandomnumber(utility.directions.east, 175); west = utility.generaterandomnumber(utility.directions.west, 175);

my generator below, have declare global static param:

public static random random = new random();

directions enumerator.

public static int generaterandomnumber(directions direction, int to) {     if ((direction == directions.south) || (direction == directions.west))         return random.next(to * -1, 0);     else         return random.next(0, to); }

the function works fine , retrieve co-ordinates below:

north: 52 south: -13 east: 82 west: -105 north: 27 south: -45 east: 172 west: -117 north: 0 south: -37 east: 161 west: -160 north: 43 south: -39 east: 26 west: -174 north: 29 south: -7 east: 75 west: -125 north: 19 south: -51 east: 93 west: -49 north: 28 south: -20 east: 26 west: -28

the issue box built around (0,0,0,0) co-ordinate , i'm not sure how out of whilst ensuring north greater south, west left map , east right map.

i suggest change approach:

  • generate point north/west corner, anywhere in appropriate range
  • generate width , height, ensuring they're positive
  • set east = west + width, , south = north - height

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
