hmm. i'm using setstate , reason code following doesn't have access new state! what gives?! yeap. it's asynchronous. i'm posting because isn't obvious new react users. react "queues" updates component's state. if need execute code block that's dependent on new state change, pass callback so: getinitialstate: function () { return { isfinalcountdown: false, } } //blablabla //then somewhere got... this.setstate( {isfinalcountdown: true}, function () {//<--- whoa. solves your synchrosity woes! console.log(this.state.isfinalcountdown); //true! } ); console.log(this.state.isfinalcountdown); //false! all of in docs, it's needs reiterated avoid common bugs new react users come across. check out: https://facebook.github.io/react/docs/component-api.html#setstate

i trying figure out how set cell in datagridview readonly. checkbox being added boolean property. therefore, looking tips how accomplished task of setting cell readonly based on column boolean property. below snippet of code.

with couchdb view, results ordered key. have been using values associated highest number. example, take result (in key: value form): {1:'sam'} {2:'jim'} {4:'joan'} {5:'jill'} couchdb sort according key.

i have api data comes in, lot of redundant (can determined id). have bloom filter built few million entries start. i using this library handle implementation. reading online: bloom filter compact data structure probabilistic representation of set of variables ensure whether elements in set present or definitely not present in set. source if have pseudocode this newdata #some dataset row in newdata: #filter.add() returns true if in set, want not in set if not filter.add(row.id): #do stuff fresh data this function called every time set of data comes in, 200 new entries/sec. is efficient way use bloom filter? a bloom filter can, given element, give 2 answers. can "i sure have never seen element before" or "i believe have seen element before". in latter case, may bloom filter incorrect (that is, it's saying "i think i've seen before" when, in fact, hasn't). that is, question answers isn't &q

i'm new git, , still having lot of trouble. say i'm working on a.cpp . modified code in a.cpp . and, change not ready commit or push. then, other people made change in a.cpp . in svn/cvs, checking out either merge or conflict. i thought git pull same thing. but, seems git pull doesn't merge/conflict. correct behavior? also, git checkout rewrites a.cpp , losing changes. is there easy way pull latest version , perform merge/conflict? before pull, stash changes . after pull, can pop stashed changes , rebase them on newest commit. first stash changes git stash you can view stashes running stash show . if haven't stashed before should see 1 stash. can pull without overwriting changes: git pull now remove changes stash , apply them checked out version: git stash pop

i have heard best condense javascript 1 file reduce number of http requests application makes. however, hold true if make use of event listeners each specific 1 page of site? for example, have 3 different pages make ajax requests load random picture server. first page listens button click, second page listens mouseover, , third page listens change in value of select field. make sense have 1 giant js file contains dom-manipulation logic, event listeners? or better define necessary dom-manipulation logic in 1 file , have 1 small js file each page page-specific event listeners page. tl;dr: event listeners elements not exist on page cost more in performance http requests additional js file? reduction of number of requests 1 reason consolidating javascript files one. the other reason this: javascript file can, after browser has downloaded once, retrieved browser cache when subsequent pages use it. fewer files means more streamlined caching. the cost of little javascript
