is possible implement single sign on using authentication server(idp) using cookies ? here scenario : we have multiple web applications (esp's) . each esp may request idp authenticate user . now idp authenticates user via desired authentication protocol , stores cookie in user's browser time stamp maybe . now next time when esp requests user authentication , first of idp checks if there exists cookie in browser , if exists authenticates user otherwise again goes through authentication process user . please guide me if on going right track . what suggesting referred "persistent login cookie authentication" or "remember me authentication" , it's standard practice. can find article on how implement such mechanism securely @ http://jaspan.com/improved_persistent_login_cookie_best_practice some frameworks spring security have concept implemented in stack. might ready-made single sign-on frameworks jasig cas tend have these features

is there way replace source of predictive texts in ios 8 custom keyboard extension , show in predictive text bar? class predictive text bar? thanks lot. i've read docs not find answers. please help. 1) can use uilexicon, technically dictionary of key-value pairs of strings wrapped in uilexiconentry object apple give example of "iphone" turning "iphone" , "nur" turning "nur n. eytan" (from address book) etc.. but can make smarter things. one smart thing example create open source project takes in json of strings , converts uilexicon :) i'd use it! 2) apple give 320 pixels width , ±215 pixels height keyboard. you prohibited , technically can't draw outside of these boundaries. companies releasing custom keyboards did reduce size of keys in 20%-25% in order add candidate view (predictive text bar) edit: can adjust height of keyboard on ios8.0 - here's pointer: ios 8 custom keyboard: changin

i had interview today , interviewer asked me how can store multiple values having same key in hashmap? gave me example-->if given list of string , suppose store length of string key , string value. i gave following solution in how using hashmap: map<integer, arraylist<string>> map = new hashmap<integer, arraylist<string>>(); integer being length of string , arraylist store strings of particular length. the interviewer said 1 way of using hashmap there way in won't requiring arraylist or other data structure. during interview, couldn't come solution , after enough googling, still have nothing. can tell me how can achieve solution question? thanks! one way without using data structure concatenating strings in values. for e.g. map.put(2,"rr*tt*yy"); map.put(3,"nnn*ggg*sss"); map.put(4,"ffff*dddd*jjjj");

hopefully should explain i'm trying achieve class a(object): def hello(self): print "hello" = a() a.b = a() a.b.c = a() a.b.d = [] a.b.d.append(a()) p = proxy(a) print p.b "b accessed" <__main__.a object @ 0xb73f3bec> print p.b.c "b accessed" "c accessed" <__main__.a object @ 0xb73f3dec> print p.b.d "b accessed" "d accessed" [<__main__.a object @ 0xb73f3bcc>] print p.b.d[0] "b accessed" "d accessed" <__main__.a object @ 0xb73e766c> print p.b.d[0].hello() "b accessed" "d accessed" "hello called" "hello" basically far walk down structure keeps returning proxy objects. best if created these proxy objects when attribute accessed first time , stored on 'parent'. goal of can logic before method called on (nested) object i had at: http://code.activestate.com/recipes/496741-object-proxying/ first layer, , cou

starting this question made understand how deinterleave left , right channel of 16 bit pcm data. my question is, how 8 bit pcm deinterleaved , "stretched" 16 bit value 16-bit pcm has same data bits , additional bits on least significant bit side specify value , add accuracy , detail. 8-bit pcm typically unsigned value centerpoint of 0x80 , , 16-bit (also applicable higher bitnesses) pcm signed integer, conversion formula is: uint8 sample8 = ...; int16 sample16 = (int16) (sample8 - 0x80) << 8;

it seems nobody had problem yet.... db2_connect found docs decrible how load default library list ( *libl ) on connection pdo nothing! i'd perform statements without specifing library name in front of file name. created job description load libraries, , when log in pc5250 emulator library online. but if run query pdo without specifying library name following returned: error executing sth in testget as400 sqlstate[42s02]: base table or view not found: 0 [ibm][system access odbc driver][db2 i5/os]sql0204 - testfile in web type *file not found. (sqlprepare[0] @ ext\pdo_odbc\odbc_driver.c:206) to use library list, need make sure connection attributes specify system naming, , avoid setting current schema. without knowledge of php + pdo, stackoveflow tag wiki gives introduction. check pdo configured proper settings db2 i, not luw or z. likewise check db2_connect settings. (why using that, instead of straight odbc?)

i'm starting learn java, , want try represent big negative numbers using arrays. let's have array [-2, 0, -5] , represents number -502 i've tried using stringbuilder, prints out -50-2 this code of right now. there way make can append first negative, , skip rest of negatives when building new string? stringbuilder sb = new stringbuilder(); for(int x = arr.length-1; x>=0; x--){ sb.append(arr[x]); } string check = sb.tostring(); system.out.println(check); initialize string buffer last character (with appropriate sign) , ignore signs rest. stringbuilder sb = new stringbuilder(); sb.append(arr[length-1]); (int x = arr.length-2; x>=0; x--) { sb.append(math.abs(arr[x])); } string check = sb.tostring(); system.out.println(check);

i'm trying obtain viewpager animation using fragmentmanager. can see animation here: http://developer.android.com/training/animation/screen-slide.html i tryed apply customanimation transaction using animation that: <objectanimator xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/linear_interpolator" android:valuefrom="-100" android:valueto="0" android:propertyname="x" android:duration="@integer/slide_in_left_animation_duration" /> but animation different i'm looking for. there way that? or have use viewpager? (i don't think viewpager right solution.. in fact app have change fragment depending on user input, can't fill arraylist priori) this library provides easy way set viewpager page change animations , has quite many types implemented. it's easy use, see it's example application , documentation. https://gi
