i want create installer application. so, have read qt installer framework , tested tutorial example , create installer , work find example. have doubt when try same process application. when compile code folder created @ same level of code: myapplication (my code) build-myapplication-desktop_qt_5_4_1_mingw_32bit-release (code compiled) so questions are: what files of compilation need copy folder myinstaller/packages/vendor/ recommended qt intaller framework? if have dependencies of qt serialport, multimedia, , others, how insert these dependecies qt installer framework? windeployqt.exe want. run on command line , give executable argument. automatically copy in required qt libraries , provide runtime redistributable installer. can use binarycreator generate installer.

this simple question, know answer. are arguments passed function calculated once , set local variables or calculated every time they're used inside function? for example: when write forloop, should set variable finds object using iteration: for(var = 0; < objects.length; i++) { var obj = objects[i]; obj.title = "title"; obj.description = "description"; } if don't set obj variable operation finding object run more once: for(var = 0; < objects.length; i++) { objects[i].title = "title"; objects[i].description = "description"; } so far i've learnt bad (although i'm guessing performance difference in modern browsers unnoticeable). my question is, if wrapped modifying methods in function , passed objects[i] function, objects[i] calculated once , set local variable obj in function or calculate every time obj called? what better practice, code or code b? code a: func...

how can create timestamp next 6 o'clock, whether that's today or tomorrow? i tried datetime.datetime.today() , replace day +1 , hour = 6 couldnt convert timestamp. need help to generate timestamp tomorrow @ 6 am, can use following. creates datetime object representing current time, checks see if current hour < 6 o'clock or not, creates datetime object next 6 o'clock (including adding incrementing day if necessary), , converts datetime object timestamp from datetime import datetime, timedelta import time # today's datetime dtnow = datetime.now() # create datetime variable 6 dt6 = none # if today's hour < 6 if dtnow.hour < 6: # create date object today's year, month, day @ 6 dt6 = datetime(dtnow.year, dtnow.month, dtnow.day, 6, 0, 0, 0) # if today past 6 am, increment date 1 day else: # 1 day duration add day = timedelta(days=1) # generate tomorrow's datetime tomorrow = dtnow + day # create ne...

for application, element access expensive, java.util.iterator no use. want more c++ iterators, can move pointer around without returning element. there in standard library this, or has de facto standard interface evolved through custom? (if not, please don't waste time posting code snippets - i'm quite able think reasonable names job). (since no 1 came around write proper answer, i'll expand comments answer.) to extent of knowledge there's no interface in standard api suits (i.e. interface iterator.skip() ). best solution using standard api methods believe, yourlist.sublist(startindex).iterator() instance. i think that, if possible, should consider creating own iterator interface. (note can let extend java.util.iterator interface able use ordinary iterator if needed.) finally, , future readers have use java.util.iterator , have access underlying list lazily, can use java.lang.reflect.proxy . note proxy objects doesn't play serialization ...

how can enable / disable each or of these 3 variables , can use same script on pages, decide if want 1 , 2 or 3 of varibles set true or false. https://jsfiddle.net/zqu3eqfm/364/ var donotcountp = ':has(.warning):contains(p)'; var donotcounts = ':has(.warning):contains(s)'; var donotcounto = ':has(.warning):contains(o)'; $('.two_column_layout').find("td.player:not("+donotcountp+"):not("+donotcounts+"):not("+donotcounto+")").css('background', 'red'); you can try way (untested code - , better code quality want extract method if-loops): var donotcountp = true; var donotcounts = false; var donotcounto = true; var getplayerquery = function() { var result = "td.player"; if(donotcountp) { result = result + ":not(':has(.warning):contains(p)')"; } if(donotcounts) { result = result + ":not(':has(.warning):contains(s)'...

a = [1,2,3,4,5]; (var in a) { if (a[i] == 4) a.splice(i,1), a.push(7); if (a[i] == 2) a.splice(i,1), a.push(0); if (a[i] == 7) console.log('seven'); if (a[i] == 0) console.log('zero'); } console.log(a); this seems work, not know details of implementation of for(..in..) loop sure safe in conditions. see paired question object modification it's safe change object in sense won't browser complain change array. note that, in example, still valid behavior if saw "seven, zero", "seven", "zero", or nothing @ being printed. on 1 hand, browsers must ensure properties deleted, before being visited, not enumerated. on other hand, browsers free to: enumerate new properties or let them out of loop enumerate properties order. that why not safe use for ... in iterate arrays when depend on index/order. indexes treated enumerable properties , can enumerated same mechanics used object's properties (where...

i'm trying text of all_msg, , hide method hide , fade in 1 letter @ time, tiny delay, code. var $all_msg = $('#welcome_msg'); function animate(i) { $all_msg.hide(); $all_msg.text.each(function(index) { $(this).delay(700 + index).fadein(1100); }) } and console giving me back: $all_msg.text.each not function i'm new coder if can me give me major boost, thanks. you need retrieve text .text() , split delimiter of choice (space list of words, or empty string list of characters), create span each of items in list , append container on page(and fade them if want): $(function() { //get welcome msg element var $all_msg = $('#welcome_msg'); //get list of letters welcome text var $wordlist = $('#welcome_msg').text().split(""); //clear welcome text msg $('#welcome_msg').text(""); //loop through letters in $wordlist array ...

how can install both (at time of writing) 1.12.5 , 1.99.6 in os x 10.8.5? afaik wireshark installs kmditemcfbundleidentifier path. for lack of answers tried following. installed stable release 1.12.5 first , moved application bundle trash, installed dev version 1.99.6 , renamed app bundle 'wireshark [dev build]', next moved older version trash applications folder. far both working. chmodbpf , wireshark cli utility launcher didn't changed. didn't notice problems in install scripts, might wrong.

i searched answer question, got various useful links when implemented idea, getting wrong answer. this understood : if m prime, simple. inverse modulus of number 'a' can calculated as: inverse_mod(a) = (a^(m-2))%m but when m not prime, have find prime factors of m , i.e. m= (p1^a1)*(p2^a2)*....*(pk^ak). here p1,p2,....,pk prime factors of m , a1,a2,....,ak respective powers. then have calculate : m1 = a%(p1^a1), m2 = a%(p2^a2), ....... mk = a%(pk^ak) then have combine these remainders using chinese remainder theorem ( https://en.wikipedia.org/wiki/chinese_remainder_theorem ) i implemented idea m=1000,000,000,but still getting wrong answer. here explanation m=1000,000,000 not prime m= (2^9)*(5^9) 2 , 5 m's prime factors. let number have calculate inverse modulo m. m1 = a%(2^9) = a^512 m2 = a%(5^9) = a^1953125 our answer = m1*e1 + m2*e2 e1= { 1 (mod 512) 0 (mod 1953125) } , e2= { 1 (mod 1953125) ...
