i have following scenario: fetch array of numbers (from redis) conditionally for each number async stuff (fetch db based on number) for each thing in result set db async stuff periodically repeat 1. 2. 3. because new numbers added redis structure.those numbers represent unix timestamp in milliseconds out of box numbers sorted in time of addition conditionally means fetch unix timestamp redis less or equal current unix timestamp in milliseconds( date.now() ) question redis data type fit use case having in mind code scaled n instances, n instances share access single redis instance. equally share load each instance read example first(oldest) 5 numbers redis. numbers unique (adding same number should fail silently) redis set seems choice reading m first elements redis set seems impossible. to prevent 2 different instance of code read same numbers redis read operation should atomic, should read numbers , delete them. if async operation fail on specific number ( steps 2...

here problem: there list of thousands of regular expressions. need regular expression matches given string. hopefully , these regexes mutually exclusive, if several regexes matching @ same time, i'm ok returning any of them. i assume of regular expressions starts literal prefix e.g.: " some_literal_string(?:\?some_regular_part)? " → " some_literal_string " i'd try following data structure make search fast: regexes = [index=prefix_length:{key=prefix:{*prefixes}] now, find prefix, need iterate index min(len(string), len(longest_prefix)) down 0 , extract subset of regexes: subset = regexes[i][string[0:i]] now need check each element match , if pattern found, return it, otherwise, continue next index . the question is: how literal prefix of regular expression in common case? i came following regular expression: (?:[^.^$*+?{\\[|(]|(?:\\(?:[^\dabbddsswwz]|0|[0-7]{3})))*(?![*?|]|{\d+(?:,\d*)?}) it's needed replace backsla...

as understand ( see section 16.3.2.1 ), es6 allows different syntaxes function / class export operands. difference refers whether exported function needs interpreted @ import function declaration, in case write: export default function () {} // (a) or function expression: export default (function () {}); // (b) . as possible related sidenote: read imports hoisted, i'm not sure means in context. taking case of example: import foo 'my_module'; // (c) as understand it, above statement save exported function in foo variable. variable hoisted, or is, , when? most importantly, difference (in terms of setting foo ) when my_module exports function using (a) , when exports using (b) ? your question bit convoluted i'll try best explain everything. let's first establish how modules work in general. module has set of exported names, each of refer local variable in module. name of export not need same of local binding. 1 of exported names can default...

instead of typedef struct { double x,y; } point; c++11 supports using point = struct {double x, y;}; unfortunately, approach not work type t template <typename t> using point = struct {t x, y;}; is there way of resolving problem? using point = ...; type alias (formally called 'alias'). i.e., it's different syntax typedef type involved named in ... . template<typename t> using point = ...; alias template , type involved again named in ... . what both aliases , alias templates have in common both must refer type-id (c++11 [basic.scope.pdecl]p3). type-ids must in turn name types . (go figure.) the problem template<typename t> struct {t x, y;} not type, class template, , established alias templates must refer types. changing code resolve your problem, i've no idea haven't said is... ;-] regarding that, please see what xy problem?

this question has answer here: adding value in hash table 1 answer i want increment value of first item one. not understand why code not working puts sales_hash sales_hash.values[0] = sales_hash.values[0] +1 puts sales_hash i adding 1 first value in sales_hash . when print out sales_hash first value remains same. doing wrong? when use hash#values receive array contains copy of values in hash. therefor, assignment not change hash rather array containing values. moreover, should aware elements in hash ordered order of key's insertion, might cause unexpected results if access "position" in hash since insertions , deletions may change order of hash. if want update value in hash, should access using it's key, example: sales_hash[:my_sale] = sales_hash[:my_sale] +1

i have hash looks follows: character = {"name: " => "#$name", "weapon: " => "#$weapon", "armor: " => "#$armor"} i want print each key , each value file looks this. name: templar weapon: sword armor: heavy armor i use basic method understand going on. i've read there modules you, such marshal, basic method involves beginner-level code. this should work you. recommend reading more on files , iterating through hashes first though. yourfile = "/some/path/file.txt" file.open(yourfile, 'w') |file| character.each{ |k, v| file.write("#{k}: #{v}\n") } end

i know title looks many people have asked question before, did lot of research , couldn't find solution solves problem. i've spent 2 days on issue please me out! i trying build simple "hello world" type of restful web service eclipse kepler service release 2, jersey, eclipse build-in maven, servlet 3.0 , tomcat 7.0. when run service using "run as" --> "run on server", there no problem loading default "index.jsp" page, keep getting http 404 error when loading service. this image shows project layout. my class implements application following: package com.ys.java.ws; import java.util.hashset; import java.util.set; import javax.ws.rs.applicationpath; import javax.ws.rs.core.application; import com.ys.java.ws.resources.myservice; @applicationpath("/ys") public class myapplication extends application { @override public set<class<?>> getclasses() { set<class<?>> s = new hashs...
