is there way perform sorting on integers or strings in instance of splfixedarray class? converting php's array , sorting, , converting being option? firstly, congratulations on finding , using splfixedarrays! think they're highly under-utilised feature in vanilla php ... as you've appreciated, performance unrivalled (compared usual php arrays) - come @ trade-offs, including lack of php functions sort them (which shame)! implementing own bubble-sort relatively easy , efficient solution. iterate through, looking @ each consecutive pairs of elements, putting highest on right. rinse , repeat until array sorted: <?php $arr = new splfixedarray(10); $arr[0] = 2345; $arr[1] = 314; $arr[2] = 3666; $arr[3] = 93; $arr[4] = 7542; $arr[5] = 4253; $arr[6] = 2343; $arr[7] = 32; $arr[8] = 6324; $arr[9] = 1; $moved = 0; while ($moved < sizeof($arr) - 1) { $i = 0; while ($i < sizeof($arr) - 1 - $moved) { if ($arr[$i] > $arr[$i + 1]) {

i tried creating file empty title or space , worked cannot find file in directory. not delete or rename file. file dir1 = new file("dir1"); dir1.mkdir(); file file1 = new file(dir1, ""); file1.createnewfile(); system.out.println(file1.exists()); returns true if execute file1.delete() or file1.renameto(...) since passing empty string child, file1 same dir1 , you're doing file1 happening directory created. here sample: public static void main(string[] args) { file directory = new file("/home/test"); directory.mkdir(); file file = new file(directory, ""); system.out.println(file.exists()); system.out.println(file.getabsolutepath()); system.out.println(directory.getabsolutepath()); file.delete(); system.out.println(directory.exists()); system.out.println(file.exists()); } output: true /home/test /home/test false false

i thinking making app can use control arduino robot (over bluetooth/wifi) using voice commands. make experience fluid, need android app speech recognition continuously running. if want robot stop, don't want press button, wait speech recognition dialog appear, command "stop", release button, wait parser parse it, , send stop command. i rather have speech text in continuous listen mode when controlling robot. , when hears keywords, sends them. can in android? did googling, , found recognizer intent, of examples found use button trigger , pretty followed scenario described above. it can done. @ link. has example code :) can make listen , when speeches word see if keyword , make robot want. http://viralpatel.net/blogs/android-speech-to-text-api/

i have object such fields: { d_name: { field_name: true }, d_date: { field_date: isodate() }, status: 'success' } i need fields starting d_ , push them 1 array.. i need fields... do mean need keys? if so: var d_keys = object.keys(obj).filter(function (key) { return !key.indexof("d_"); }); if want values: var d_values = object.keys(obj).filter(function (key) { return !key.indexof("d_"); }).map(function (key) { return obj[key]; }); note uses various es5 methods ( object.keys , array.prototype.filter , array.prototype.map ), depending on environment may need appropriate shims. here working examples of both snippets.

i need assistance constructing regular expression in coldfusion application. apologize if has been asked. have searched, may not asking correct thing. i using following search email subject line issue number: rematchnocase("[0-9]{5}", mailcheck.subject) the issue number contains numeric values, , should 5 digits. working except in cases have longer number appears in string, such 34512345. takes first 5 digits of string valid issue number well. what want retrieve 5 digit numbers, nothing shorter or longer. placing these list looped on , processed. perhaps need include spaces before , after in regex desired result? thank you. the general way exclude content occurring before/after match use negative lookbehind before match , negative lookahead afterwards. numeric digits be: (?<!\d)\d{5}(?!\d) (where \d shorthand [0-9] ) cf's regex supports lookaheads, unfortunately not lookbehinds, wouldn't work directly in rematch - doesn't matte

i've seen node.js boilerplates autoload model files using "require()" in several different ways. i'm used using "var variable_name = require('app/models/model.js') , model = require('app/models/model.js') i'm wondering how use model when required this: require('app/models/model.js') let's suppose model.js has attribute "name" , method ".save()". how model can used? if don't assign object returned require, can't access later. here examples notes: this run top-level code, not keep reference module object require('app/models/model.js') this run top-level code , 1 instance (note i'm assuming model.js exports constructor function common opposed name , save properties describe directly, think unlikely what's there). var mymodel = new require('app/models/model.js') this store model constructor can make many instances need. var model = require('app/mo

i have table has, apart others, 2 columns named partition_name , xkey. want is, when user logs in system, has xkey found in xkey column, display rows "linked" xkey (the rows have xkey). moreover, have check partition_name column. if user logs in, , corespondend of xkey in partition_name ep, have display rows, not related xkey. i've done first part (display rows based on xkeys) can`t figure out how display rows if partition_name of xkey ep. this how in rb 3.0; don't know how 2.0 different, may work. i don't know how system set up, we'll assume there's way determine user , user's partition_name is. need set hidden parameter set value of user's partition_name; we'll call parameter pn_param; need set hidden filter, we'll call xkey_param. set filter on dataset. set value [xkey] or whatever name of column is. make sure type text. set operator = set expression following: =iif(parameters!pn_param.value = "ep", "
