for assignment, specification simple. given text file of arbitrary length (possibly thousands of characters). considered correct, must contain matching pairs of brackets { } , [ ] , , ( ) . bracket pairs may nested arbitrary depth (but not need worry stack overflow) arbitrary amounts of text between brackets. file contains no brackets trivially correct. when discover pair of mismatched brackets, must report brackets , index in file. first character in file index 0. example, if file contains file has open { , { followed ) , } , text. program should report mismatch because { @ index 36 closed ) @ index 50. can think of start of file super opening bracket not match closing bracket. if file contains many closing brackets, mismatched opening bracket start of file. should use string stx (old ascii start of text ) report this. example, closing ] has no matching open [. in case, program should report mismatch because stx @ index -1 closed ] @ index 13. similarly, can think of end o

i'll start code: var s = ["hi"]; console.log(s); s[0] = "bye"; console.log(s); simple, right? in response this, firebug says: ["hi"] ["bye"] wonderful, chrome's javascript console (7.0.517.41 beta) says: ["bye"] ["bye"] have done wrong, or chrome's javascript console being exceptionally lazy evaluating array? thanks comment, tec. able find existing unconfirmed webkit bug explains issue: https://bugs.webkit.org/show_bug.cgi?id=35801 (edit: fixed!) there appears debate regarding how of bug , whether it's fixable. seem bad behavior me. troubling me because, in chrome @ least, occurs when code resides in scripts executed (before page loaded), when console open, whenever page refreshed. calling console.log when console not yet active results in reference object being queued, not output console contain. therefore, array (or object), not evaluated until console ready. case of lazy e

is there way can convert hierarchy string table form? suppose input a.b.c.d ouput should table traverses above input: a = {} a.b = {} a.b.c = {} a.b.c.d = {} thanks. the obvious solution parse string , construct hierarchy table that. more clever solution let lua you. bit of metamagic , function environment manipulation can done: dump = require 'pl.pretty'.dump -- convenient table dumper penlight function createtable(str) local env_mt = {} env_mt.__index = function(t, k) rawset(t, k, setmetatable({}, env_mt)) return rawget(t, k) end local env = setmetatable({}, env_mt) local f = loadstring("return "..str) setfenv(f, env) f() return env end dump( createtable "a.b.c.d" ) this outputs: { = { b = { c = { d = { } } } } }

i'm rewriting game i've designed in flash/as3.0 javascript , having trouble wrapping head around prototypes, having learned classes. i've read ton of info , still not quite sure how apply scenario. so... in as3.0 project had level class, had guts of happens in levels of game, enter_frame functionality etc. extended class each level, level specific details such item placement, terrain details etc... question how efficient , 'proper' way this. right have 2 functions: function level() { //generic level functionality } function level1() { //level1 specific functionality } then i've read should have set level1.prototype = new level(); but have found executes within level function @ runtime, don't want. ideally i'd start button instantiate level1, , level1 have properties , methods of level - and, if possible, execute within level1's , level's constructor when happens... possible? i'm sure it's obvious can't seem click, s

i'm not asking ndef in general - obvious need format data interchange. i'm working on application must read both - non-ndef (mifare classic in particular) , ndef nfc chips. i've separated routines reading both , managed detection part: tag tag = intent.getparcelableextra( nfcadapter.extra_tag ); string[] techlist = tag.gettechlist(); ( string tech : techlist ) { if ( mifareclassic.class.getname().equals( tech ) ) { string uid = byte2hexstring( tag.getid() ); // todo } else if ( ndef.class.getname().equals( tech ) ) { return this.readndef( intent ); } } but i'm not sure the abstraction part - should try encode data non-ndef (mc) chip ndef (if that's possible), or should separate these abstraction layers? there advantage of encoding data ndef? the advantage of using ndef formatted data more portable across different systems. ndef compliant data should work not on android, on windows8 or blackberry devices (with

i wrote tcp relay server works peer-to-peer router (supernode). the simplest case 2 opened sockets , data relay between them: clienta <---> server <---> clientb however server have serve 2000 such a-b pairs, ie. 4000 sockets... there 2 known data stream relay implementations in userland (based on socketa.recv() --> socketb.send() , socketb.recv() --> socketa.send() ): using of select / poll functions (non-blocking method) using of threads / forks (blocking method) i used threads in worst case server creates 2*2000 threads! had limit stack size , works right solution? core of question: is there way avoid active data relaying between 2 sockets in userland? it seems there passive way. example can create file descriptor each socket, create 2 pipes , use dup2() - same method stdin/out redirecting. 2 threads useless data relay , can finished/closed. the question if server should ever close sockets , pipes , how know when pipe broken log fact?

i discovered today if ssh-forward local port x ssh server port y, , no process listening on port y, can still connect local port x (i don't usual "connection refused" error). i did test 2 different ssh clients on windows host connecting linux server. after bit of reflexion, came conclusion pure network point of view, behaviour should expect: ssh client listening on localhost:x, connection possible. nevertheless, leads problematic situation in have apparently connected socket talks nobody. sending data on socket successful operation. so question: ssh protocol manage situation in ways, i.e. have strategies detecting situation? , if yes, may hope support feature on ssh clients , apis (today i'm using ssh.net, not seem offer feature). if not, how proceed detecting situation? timeout on answer? thanks help, alberto. the logical behavior close client connection if server can't connect remote side, not better hanging connection. also there can

i have existing data_base using windev want convert database(and extract data (file .fic) windev sql-server 2012 use them . information application called payroll.exe 4.0.0.1 version. version of windev must download extract data ? need in sql-server it?? this depends on version of dll found windev application. example wd170hf.dll windev 17, wd90hf.dll windev 9. the easiest way can think of doing u want either using program called wdmap (it's installed windev). export table xls/csv , import 1 sql-server. far not best or fastest solution will/should work. or use odbc connector (this 1 can downloaded separately if not mistaken). comes windev installation. note on windev u can download & install full version site. u need dongle start ide. (u can use tools (like wdmap) without dongle. officially not allowed install ide if u not have dongle. express version won't allow u edit source files made full version.
