im trying parse , show json content in tableviewcell, goes wrong. json here: http://bumpee.net/xcode/index.php -(void)connectiondidfinishloading:(nsurlconnection *)connection { nsdictionary *json = [nsjsonserialization jsonobjectwithdata:webdata options:0 error:nil]; nsarray *arr = [json objectforkey:@"feed"]; for(nsdictionary *aaa in arr) { nsdictionary *one = [aaa objectforkey:@"1"]; nsstring *oneprint= [one objectforkey:@"name"]; [array addobject:oneprint]; } [[self tableview ] reloaddata]; } the problem arr nsdictionary not nsarray , when iterate on with for (nsdictionary *aaa in arr) [...] you go through nsstring keys, , not values.

i've got {cache:true{ $http requests. know if enabled, data returned asynchronously, though, find response times surprisingly long. i'd know if normal, or more clear, shouldn't expected initial request response time higher same (but next) request response time ? for example, cache enabled both $http requests: /foo/api/yellow this returns data, after promise resolved, taking 3 seconds. expect cached angularjs, since i've enabled cache. after few moments, new request made: /foo/api/yellow this returns data, though supposedly cached in first request, response time same or higher 3 seconds. said, know though cache true, data returned asynchronously response times normal, or there wrong ? if normal, guess best thing do, create new service, save cached data , check if data there , synchronously maybe ? my current code looks this, first request: $http.get(mysettings.apiurl + '/foo/api/yellow', { cache: true }); the second request same! i...

ok, having particularly bad day , can't seem figure out why line of code not returning results should be. registrykey rksubkey = registry.currentuser.opensubkey(@"\software\<<path key>>", false); the value written registry form 2 text boxes, writes should , there value in registry , cannot life of me see why rksubkey returning null value. i read on msdn forums related 64 bit software accessing 32 bit registry .. in app settings 32 bit preferred. any appreciated. the problem in leading backslash, delete :) registrykey rksubkey = registry.currentuser.opensubkey(@"software\<<path key>>", false);

my problem want delete 1 record on table "provicional" if "id" , "password" match... have simple code work id , want delete if both match! $sql = "delete `provicional` `id` in ('3','basico')"; many a not popular way of doing in mysql be: delete provicional (id, password) = (3, 'basico') note can add more 2 elements in each list. tip: not use apostrophes ' around numeric fields.

say have generator in python , want iterate on in except first 10 iterations , last 10 iterations. itertools.islice supports first part of slicing operation, not second. there simple way accomplish this? not there not simple way, there not way @ all, if want allow generator (or iterable). in general, there no way know when 10 items end of generator, or whether generator has end. generators give 1 item @ time, , tell nothing how many items "left". have iterate through entire generator, keeping temporary cache of recent 10 items, , yield when (or if!) generator terminates. note "or if". generator need not finite. infinite generator, there no such thing "last" 10 elements.

i have many strings of form name1, name2 , name3, 0, 1, 2 or name1, name2, name3 , name4, 0, 1, 2 , split vector 4 elements first 1 whole text string of names. problem strsplit doesn't differenciate between text , numbers , split string 5 elements in first case , 6 elements in second example. how can tell r dynamically skip text part of string variable number of names? you have 2 main options: (1) grep numbers, , extract those. (2) split on comma, coerce numeric , check na s i prefer second splat <- strsplit(x, ",")[[1]] numbs <- !is.na(suppresswarnings(as.numeric(splat))) c(paste(splat[!numbs], collapse=","), splat[numbs]) # [1] "name1, name2 , name3" " 0" " 1" " 2"
