how can php see client side cookies? to elaborate: when working php & javascript, understand php gets processed on server side. while javascript happens on client side. in javascript can check , set these client cookies. makes sense. however, php, if check client cookie value part of conditional statement sets , how php able see clients cookie value while php happening on server side? here's example of php conditional lives in php file: <?php if ($_cookie["name"] == “mickey”) { setcookie(“fulsome”, “mickey mouse”, time()+3600); } ?> there no such thing client side cookie. a cookie piece of data associated set of urls in browser. every time browser makes http request 1 of urls, cookie included in request headers. they designed set via http response headers. an api added browsers allows them created , set javascript. these still regular cookies though , included in every request associated urls. it possible mark cookie http_onl...

i'm studying database mechanism , see there 2 mechanisms: table level locking , row level locking . don't see column level locking , when google, see no document tell except link: database locking . in link: a column level lock means columns within given row in given table locked. form of locking not commonly used because requires lot of resources enable , release locks @ level. also, there little support column level locking in database vendors. so, vendors support column level locking ? , can tell me more detail, why column level locking requires lot of resources row level locking . thanks :) a lock cannot, in , of itself, require anything. it's abstract verb acting on abstract noun. why should locking column cost more locking byte, or file, or door? wouldn't put lot of stock in link. the answer question lies in why locks exist -- protect -- , how dbmss engineered. one of primary jobs of dbms manage concurrency: give each use...

i have issue current program supposed take user input, encrypt allowing choose how want shift by, save file. unknown reasons program seems capable of saving file missing out encryption. appreciated. text = "abcdefghijklmnopqrstuvwxyz 1234567890-=!£%^&*" def main(): #if want save file after encrypting if statement ans = input("would save file of read file, press w or r").lower() if ans == "w": text = input("what text want enter").lower() caeser(text) save_file() elif ans == "r": text = input("what file name want enter").lower() caeser(text) # organise loop & function def caeser(text): shift = int(input("how shift?: ")) shifted_list = [] letter in text: character_lower = letter.lower() ascii = ord(character_lower) shift = shift % 26 shifted_letter = ascii + shift shifted_char = chr(shif...

so, see usefulness of lambda functions when used replace functors, when want use them in object oriented programming (with classes) setting in general , why? okay, little more (and less) helpful response comment. closures (that is, functions declared inside other functions, capture outer function's variables) interesting back-channel way implement classes. watch: auto makecounter(int initialcount) { int currentcount = initialcount; struct { std::function<void()> increment = [&]() { currentcount++; }; std::function<int()> getcount = [&]() { return currentcount; }; } thecounter; return thecounter; } now thecounter structure 2 members, 1 increments count , other retrieves current count. notice struct doesn't need store current count; instead implicitly held 2 lambdas, share currentcount between them. there's few problems this. it doesn't compile. not mostly. there ton of things wrong code snippe...

when animate change view's transform, reset change in animation before first animation finishes, everything's great (shown here rotation). animation smoothly switches new target: but when scale, animation overshoots magnificently: here's breaking code: uiview.animatewithduration(1) { self.someview.layer.transform = catransform3dmakescale(0.001, 0.001, 1) } uiview.animatewithduration(1, delay: 0.5, options: nil, animations: { self.someview.layer.transform = catransform3didentity }, completion: nil ) has else seen this? doing wrong? edit: , there workaround? edit 2: believe duplicate of this question , voting close. this blog post provides answer: in ios 8, uiview animations additive, , has unfortunate result scale animations. basically, second animation happens together with first animation. solution explicitly remove original animation before starting new one: view.layer.transform = view.layer.presentationlayer...
