perl - How to resolve issues with accessing paths containing @ in directory name - 


wa=/perl/temp@23 (env param)      if (defined $env{'wa'}) {         $env{'ac'} = "$env{'wa'}/right";     }     eval(qq|use lib "$env{'ac'}/lib"|);

error-- possible unintended interpolation of @23 in string @ (eval 1) line 1.

i tried below solutions , none of them of great help.

attempt 1: didn't work

$env{'wa'} =~ s/(^.*)@(.*)/$1\@$2/; if (defined $env{'wa'}) {     $env{'ac'} = "$env{'wa'}/right"; } eval(qq|use lib "$env{'ac'}/lib"|);

i saw 1 more issue this. when worked once..no clue why , how worked,but lib not added @inc path.

attempt 2: didn't work - saw in post \x40 represents @

$env{'wa'} =~ s/(^.*)@(.*)/$1\x40$2/; if (defined $env{'wa'}) {     $env{'ac'} = "$env{'wa'}/right"; } eval(qq|use lib "$env{'ac'}/lib"|);

attempt 3: 1 error next

$env{'wa'} =~ s/(^.*)(@)(.*)/$1\@$3/; if (defined $env{'wa'}) {     $env{'ac'} = "$env{'wa'}/right"; } $str = $env{'ac'}; eval(qq|use lib "$str/lib"|); use module

error: can't locate module in @inc atleast don't unintended interpolation @

can give me pointers on how resolve issue.

why need string eval?

begin {     if (defined $env{wa}) {         $env{ac} = "$env{wa}/right";     } }  use lib "$env{ac}/lib";

or, if want set @inc if ac defined:

use if defined $env{ac},     lib => { no warnings 'uninitialized'; "$env{ac}/lib" };

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

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
