node.js - I am getting `getAddrInfo ENOTFOUND localhost` on running simple node server even though localhost is present in /etc/hosts (MacOS El Capitan) -


i have weird thing happening while setting , running normal node js server.

when run node server.js, following error:

server running @ http://localhost:1337/ events.js:160   throw er; // unhandled 'error' event   ^ error: getaddrinfo enotfound localhost        @ errnoexception (dns.js:28:10)        @ getaddrinforeqwrap.onlookup [as oncomplete] (dns.js:76:26)

when open http://localhost:1337/ in browser, says page not exist.

when run sudo node server.js, runs fine without error , can access site @ https://localhost:1337

here /etc/hosts file:

127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost

my server.js:

// require need var http = require("http"); // build server var app = http.createserver(function(request, response {     response.writehead(200, {         "content-type": "text/plain"     }); response.end("hello world!\n"); }); // start server, baby app.listen(1337, "localhost"); console.log("server running @ http://localhost:1337/");

other details

  1. os: mac os (el capitan)
  2. node js version: 6.10.3 (installed globally)
  3. npm version: 4.5.0 (installed globally)

following questions

  1. why above server.js file working admin access not normal user?
  2. does globally installed node work admin access?
  3. is there else in mac os can affect dns lookup other /etc/hosts? have flushed dns cache , reboot os make sure older dns lookup not being used.

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 ...
