php - Does rehashing a randomly salted password at login increase security? -

-
i working on project in php, , wondering how make system secure possible. using password_hash hash passwords , store them in database. wondering: rehashing , re-saving new salted hash database increase security, or illusion? i don't think increase security, no. have 2 risk scenarios: the cracker breaks server , stays there time undetected. in case, passwords can captured programmatically, users log in. requires less effort brute-forcing strong hash algorithms. the cracker breaks in, steals copy of database, , in response sysadmin plugs security hole , restores server backup quickly. in second case, cracker has set of usernames, email addresses , hashed passwords, may wish try brute-forcing. there no advantage had if these hashes created once or thousand times. it's worth remembering we're trying guard against here. if security of website has been breached, there knock-on effect users have used same username/password combination @ other popular service

ios - Apple Pay in the South African market -

-
i want implement apple pay in 1 of applications. while reading, found post saying supported uk , , not south africa. if upload build having apple pay functionality, work south africa? also, app rejected. from own question: it supported uk , us will work south africa? no if application going available in south africa, user's won't able use apple pay (yet. apple pay may rolled out in future) , should implement solution if application available worldwide, users in , uk able use apple pay, however, no others , should either implement solution replace apple pay, or include option users can't access apple pay. i think it's unlikely app rejected including apple pay if app available worldwide. however, part of question off topic, , can't provide definite answer.

python - Create variables in Django views.py and access them at later point -

-
let's have following 2 functions in views.py: def foo(request): class_instance = someclass() return httpresponse('whatever') def bar(request): # here want access class_instance initially, foo() called, , @ later point bar() called, in want access variable class_instance . is there way of accomplishing while neither using request.session nor django models (e.g. django.db.models )? (nb: had luck global variables in views.py, bad idea anyway , somehow didn't work) you can put variable module constant, if it's not prone changing much. class_instance = someclass() def foo(request): return httpresponse('whatever') def bar(request): # here want access class_instance then both methods have access that, but keep in mind, functions can't change constant's value way . ps: can change value of global: class_instance = someclass() def foo(request): global class_instance class_instance = someclass() #

c++ - What is the upper bound of BigInteger with character array implementation? -

-
if impement biginteger character array (in c++), in terms of power of 10, upper bound in 32bit system? in other words, - 10^x < n <= 10^x (first character reserved sign). what x in 32 bit system? please ignore have reserved memory os , consider 4gb memory addressable us. an 8-bit byte can hold 2 8 , or 256 unique values. 4gb of memory 2 32 , or 4294967296 bytes . or 4294967295, if subtract 1 byte want reserve sign that's 34359738360 bits . this many bits can hold 2 34359738360 unique values. - 10^x < n <= 10^x (first character reserved sign). what x in 32 bit system? wolfram alpha suggests - 10^1292913986 < n <= 10^1292913986 largest representable powers of 10. so x 1,292,913,986.

javascript - HTML5 audio: trying to make a queue -

-
i working on text-to-speech generator using javascript , html5 audio elements. idea transform string of ipa (international phonetic alphabet) sound. in function talk() , take string , split it. put corresponding sounds queue , try play playq(q) function. but function doesn't seem work. can make play first sound. q[0].play; working, rest of playq(q) function not. i'm thinking either because of q.shift() method, have tried q[1:] , or because of recursivity. function talk(){ var queue = [] var str = document.ipatts.phonetic.value var letters = str.split("") (x in letters) { queue.push(document.getelementbyid(letters[x])) } playq(queue); } function playq(q){ q[0].play(); var z = q.shift(); q[0].onended = function() {playq(z)}; } nevermind! got work using var z = [] (x in q) { if (x > 0) { z.push(q[x]) } } in stead of var z = q.shift();

-
i have created local table , inserted data. long don't use is secure fields works fine. when use is secure fields encrypted text these fields. seems decrypt function missing. how solve this? for accessing fields use: var field_value = data.execute("select f3 testtable rowid = 3;"); alert("row 3:" + field_value); actually, should encrypted values if try kind of sql execute statement, regardless how many rows selected issecure. mean, if there issecure field, should seen encrypted. selecting rows insecure or of them insecure, shouldn't change anything. the new release of smartface app studio available right now. ( http://account.smartface.io/account/login?returnurl=%2f ) i tested case, works fine new release. by way, if want reach actual value in table, try below code : data.mydataset.move(2); //lets reach same row wrote above move alert("row 3 : " + data.mydataset.f3); you should write dataset's name instead of my

javascript - Function calling 2 ways with multiple arguments -

-
as of know can create simple function this. function calc(a,b){ return a+b } calc(1,1); //returns 2 we can make this function calc(a){ return function(b){ return a+b } } calc(1)(1); //returns 2 what if had multiple arguments? function calc() { function r(arg) { var = []; for(var = 0, l = arg.length; < l; i++){ a[i] = arg[i]; } return a.reduce(function(p, c) { return p + c; }); } var res = r(arguments); return function() { res += r(arguments); return res; } } this works calc(1,2)(1) doesn't calc(1,2,1) is there way combine both versions? means when calling calc(1,1) call calc(1)(1) , both still return 2. or calc(1,2,3) calc(1,2)(3) calc(1)(2,3) return 6 it needs know how many arguments calculation after ;-) you can make function turns things sort of function : function curry(f){ var args = []; return addargs; func
