const functions = require('firebase-functions'); const admin = require('firebase-admin'); admin.initializeapp(functions.config().firebase); var fs = require('fs'); var moment = require('moment');    exports.hellohttp = functions.https.onrequest((req, res) => {       if (req.body.result && (req.body.result.parameters || req.body.result.action || req.body.result.contexts)) {         var userquery = req.body.result.resolvedquery || {};         var action = req.body.result.action || {};         var parameters = req.body.result.parameters || {};         var plan_id = req.body.result.parameters.plan_id || {};          createjson();         var data = json.stringify(cjson);         fs.writefilesync('psedo json.json', data);           var createjson = function() {                 userprofile();                 var time = moment().format();                 var cjson = {                     timestamp: time,                     lang: 'en',                     userinfo: {                         planid: iplanid,                         currentwork: icurjob,                         workexp: iyearexp,                         numberjob: inumjob                     }                 };             }          var userprofile = function() {                  if (action == "get_plan_id") {                     inplanid();                     if (action == "update_user_info" && cur_job !== null && num_job !== null && yr_exp !== null) {                         incurjob();                         inumjob();                         inyearexp();                     }                 }             }          var inplanid = function() {             var iplanid = req.body.result.parameters.plan_id;             return [iplanid];         }         var incurjob = function() {             var cur_job = req.body.result.parameters.cur-job || {};             var icurjob = req.body.result.parameters.cur-job;             return [icurjob];         }         var inyearexp = function() {             var yr_exp = req.body.result.parameters.yr-exp || {};             var iyearexp = req.body.result.parameters.yr-exp;             return [iyearexp];         }         var innumjob = function() {              var num_job = req.body.result.parameters.number-job || {};                 var inumjob = req.body.result.parameters.number-job;                 return [inumjob];             }      }      res.setheader('content-type', 'application/json'); //requires application/json mime type     res.send(json.stringify({         "speech": response,         "displaytext": response      })) })

function expressions hoisted w/o value other variables do.

if want hoist value should use function statement instead

 function createjson() {             userprofile();             var time = moment().format();             var cjson = {                 timestamp: time,                 lang: 'en',                 userinfo: {                     planid: iplanid,                     currentwork: icurjob,                     workexp: iyearexp,                     numberjob: inumjob                 }             };         }

and same rest of functions.

console.log(typeof x, typeof y)    var x = function(){}  function y() {}

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
