Is it worthwhile to explicitly write Integers as bits in Swift? -


i learned how binary numbering system works (how write integers in bits), , wondering if worthwhile thing include in software. performance big me, , know writing integers in bits faster not. i'm wondering how faster. i'm not asking number on scale, want know if subtle difference, maybe 0.1 second quicker calculation, or if more noticeable, such 1 second quicker.

just thinking readability , safety of code explicitly written integers in bits sounds mess waiting happen, want know if tradeoff worth me.

i know bit of loose question have stated, let me try , improve here:

will performance have noticeable change if store integers explicitly using bits? (i consider "noticeable change" on 0.5 seconds quicker)

i'd have thought came '70s (like me) when "performance" equated "paging", "core memory", "megahertz", , like. prefaced things "i learned...". here's should matter you:

  • what ios/macos version targeting baseline?
  • is app graphically intensive? , if so, have "handed off" can gpu?
  • are efficiently using both threading , asynchronous calls? specifically, accessing "cloud" and/or database might using properly?

there's many more questions should consider before how "write integers bits", if drift, shouldn't concerned such thing. (and sure, graphics using gpu instead of cpu "kinda sorta" asking.

last question, maybe important one: have tried - @ related concerns , relevant app working on - on actual device? (be iphone 5 or macbook air.) i'm betting won't have concerns performance between how integer stored @ bit level.

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

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
