i'm wondering there quicker, more efficent way of comparing 2 text files check equality comparing md5 of 2 files? i'm using javascript. if have calculate md5 of files each time this, might check lengths same, compare them byte byte. calculating md5 (or other hash) means running through whole file anyway. pseudocode: bool filesaresame(file1, file2) { if (file1.length != file2.length) return false; (int i=0;i<file1.length;i++) { if (file1[i] != file2[i]) return false; } return true; }

for small comments widget. i'm trying include widget .php file @ wish- in practical way user just: <?php include "comments.php"; ?> i'm trying create admin-login-panel right widget, offer logged admin delete posts (and more other options). the problem is : have start use $_session , prevent admin having login on , on again @ each change / page-refresh. but, using sessions inside widget can see header , session warnings ...olready started... ....and on. is not option force user put pages top 'session_starts', i'd keep things simple. php- include widget. can still keep trying php sessions or should try else? in advance suggestion. alright, information have given us, problem is: php sessions uses special cookie sent in header. must perform session_start(); before other content sent browser, can set cookie in header. unfortunately, looks have start session outside of including of widget. why starting session outside of widget...

instead of deleting row on delete want update column called "deleted" time delete happened (and maybe set "deleteduserid" column). of course, on object->find operations want exclude deleted rows. possible or crazy? you'll want use beforefind() model callback filter rows deleted=1. check $querydata['conditions'] , appending $querydata['conditions']['model.deleted'] = 0 if 'model.deleted' or 'deleted' not set. for more details, see http://book.cakephp.org/view/76/callback-methods .

i not sure of how this, want create array , able add new items array. since items supposed random number, when new instance created checked against rest of array , sure number has generated not in array. how accomplish this? i looked @ Šime vidas's answer , seems work, tried shorten var arr = []; function add(a) { var n = ~~(math.random() * 100); (var = 0; < a.length; i++) { if ( a[i] === n) { a.push(n) } } } (var i=0; i<5; i++){ add(arr) } document.getelementbyid('output').innerhtml += arr; and don't understand why wouldn't work. pretty same thing, correct? var arr = []; function add(a) { var n = ~~(math.random() * 1000); !is(a, n) && a.push(n); } function is(a, n) { (var = 0; < a.length; i++) { if ( a[i] === n ) { return true; } } return false; } the add function creates random integer number between 0 , 1000, , adds array. is function checks whether n number somewhere inside...

i have function in class: private function fireitemcreated(data: bytearray): void { settimeout(function(): void { var event: itemcreatedevent = new itemcreatedevent(data); dispatchevent(event); }, 1000); } this function called dispatch item created event when image thumbnail created. but delays event on time prevent user interface freezes. , i'm guessing happen if garbage collector executes after fireitemcreated function call before timer event. closure removed or stays until executed? it can't happen. if function called settimeout called. function-object passed settimeout creates strong closure-binding linked execution context , all settimeout callback functions protected ( strongly held ) host engine (imagine there invisible var timeouts = [] can't access). wouldn't fun if timers magically swallowed evil grime captain. good question , happy coding. the issue described can happen in other languages , implementati...

i'm creating application core function tracks various data on time (blood glucose levels, insulin dosages, food intake etc) , i'm trying decide how best organize information in database. at basic within particular umbrella event, thought of having single events table fields properties might come up. may unwieldy, though, because vast majority of fields end being blank many of entires; i'm not sure if that's problem. benefit of way easier call , display events. since many of events have 'timestamp' in common, question whether belong on same table. i'm not sure makes sense have table every kind of event, because taken separately of events have 1 property other timestamp, , have co-mingle. (many types of data not come in group) some types of events have durations. comparatively rare. 1 class of events rate stays same unless rate altered or temporary override (those ones i'm worried about). simple binary tags (which planning on having linking table...
