the questions : for (a) seems not true, can fin example of flow growing without e being saturated. for (b) seems true, yet not sure how prove it. maybe because of min cut max flow theorm, on min cut had grew. for (c) seems false. flow grew because e changed e might have not grew 5. (1) seems true me - if managed increase maximum flow, means found new path source sink (that did not exist before increasing edge e ). e must in new path, if e not saturated before, path have existed in original graph. (2) false. take graph this: s --20-- n --20-- t where s source , t sink, there 2 min-cuts ( {(s, n)} , {(n, t)} ), increasing either (s, n) or (n, t) won't change maximum flow. (3) false. take graph this: s --20-- n --25-- t if increase capacit of e = (s, n) 10 , new maximum flow 25 , did not increase value of e 5 .

say have following code: $('.some-class a').click(function() { // }); will jquery search dom each time .some-class a clicked? or dom searched once? i'm wondering if improve performance if make $('.some-class a') variable , change to: var $someclass = $('.some-class a'); $someclass.click(function() { // }); in case : $('.some-class a').click(function() { // }); this instruction executed once : jquery search dom once, find requested elements , attach click events them. end. in case : function hidestuff(){ $('.some-class a').hide() } jquery have search dom every time function called. in order avoid that, store objects in variable (it's called caching) : var $elems = $('.some-class a') function hidestuff(){ $elems.hide() } every time hidestuff() function called, jquery won't have search dom, it's got elements stored in memory, it's faster.

how, implement code igniter rest api outputs ajax outputting json. i'm unsure how use rest api deleting , adding json. how delete item json , database. 1. rest api routing let's start routing of api - if apply best practice api want use http verbs (post/put/get...). ( read more on http verbs , rest here ) if on codeigniter 2.x read question , answer if on codeigniter 3.x read documentation on other side, if planning use api internally , scope of project limited can ignore http verbs , make post , calls controllers. 2. creating json response generally not need use views - can have controllers echo json response. here example of fictional api has api call actor database of actors. /* ---------------------------------------------- | example of api method actor | database of actors: | call: http://example.com/api/getactorbyid | parameter: actor_id | method: post */ public function getactorbyid(){ // let's first actor id post data...

it doesn't happen time, visual studio code cannot find variable in other file, , don't know why. for example, have index.html <script src="monitor.js"></script> <script src="notificationmanager.js"></script> notificationmanager.js var notificationmanager = function() { this.attentionrequest = function() { console.log("attention"); }; } var notificationmanager = new notificationmanager(); in monitor.js: notificationmanager.attentionrequest();//vscode don't find it happens you trying access variable/function declared in js file not available @ time of access. hence, need change order of js files update from <script src="monitor.js"></script> <script src="notificationmanager.js"></script> to <script src="notificationmanager.js"></script> <script src="monitor.js"></script>

yesterday made aware of disruptive update microsoft released. 1 of windows 10 updates, microsoft made default printer dynamically changes whatever last printer used. while understand how useful in many situations, there many situations in problematic. example if printed small label on dedicated label printer , went print out 8.5" x 11" report without selecting printer. result lot of wasted labels. particular situation, unfortunately rather common experience. for reason, need find way , disable new "feature". see there option going settings -> devices -> printers , scanners. purpose, though, need can automated. have couple hundred computers need perform change on. i looked around bit, unable find complete answer elsewhere , decided answer own question. the answer put reg add command in batch file. command is: reg add "hkcu\software\microsoft\windows nt\currentversion\windows" /v "legacydefaultprintermode" /t reg_dword /d...

the question kinda hard put in words hope make sense what's best practice? this if($value < 5) { //do } or this if(validvalue($value)) { //do } function validvalue($value) { if($value < 5) return true; } this best way validate value rather creating function that's not required. if ( $value < 5 ) { #do }
