i little confused definition of interarrival time, mean time between 2 sent packets? , using opnet, observed shorter interarrival time is, higher network load, correct conclusion? in short: yes. interarrival time defined time between "start" of 2 events.

i'm getting confused returning multiple groups in python. regex this: lun_q = 'lun:\s*(\d+\s?)*' and string is s = '''lun: 0 1 2 3 295 296 297 298'''` i return matched object, , want @ groups, shows last number (258): r.groups() (u'298',) why isn't returning groups of 0,1,2,3,4 etc.? your regex contains single pair of parentheses (one capturing group), 1 group in match. if use repetition operator on capturing group ( + or * ), group gets "overwritten" each time group repeated, meaning last match captured. in example here, you're better off using .split() , in combination regex: lun_q = 'lun:\s*(\d+(?:\s+\d+)*)' s = '''lun: 0 1 2 3 295 296 297 298''' r = re.search(lun_q, s) if r: luns = r.group(1).split() # optionally, convert luns strings integers luns = [int(lun) lun in luns]

i have sql select statement this: select firstname, lastname, age people this return me table: peter smith 34 john walker 46 pat benetar 57 what want insert column headings first row like: first name last name age =========== ========== ==== peter smith 34 john walker 46 pat benetar 57 can suggest how achieved? could maybe create temporary table headings , append data 1 this? neither of answers above work, unless names come after "first" in sort order. select firstname, lastname ( select sorter = 1, firstname, lastname people union select 0, 'firstname', 'lastname') x order sorter, firstname -- or whatever ordering need if want non-varchar columns well, cons (at least): all data become varchar. if use visual studio example, no longer able recognize or use date values. or int values. or other matter. you need explicitly provide format datetime values dob. dob valu...

basically have php class that want test commandline , run method. sure basic question, missing docs. know how run file, php -f not sure how run file class , execute given method this work: php -r 'include "myclass.php"; myclass::foo();' but don't see reasons besides testing though.

i wondering whether in c possible peek in input buffer or perform similar trickery know whether call fgets block @ later time. java allows calling bufferedreader.ready(), way can implement console input this: while (on && in.ready()) { line = in.readline(); /* line */ if (!in.ready()) thread.sleep(100); } this allows external thread gracefully shutdown input loop setting on false; i'd perform similar implementation in c without resorting non portable tricks, know can make "timed out fgets" under unix resorting signals or (better, though requering take care of buffering) reimplement on top of recv/select, i'd prefer work on windows too. tia suggest go socket i/o routines,preferably poll() required millisecond timeout , can interpret timeout ( return value = -1 ) unavailability of data in input buffer. in opinion,there no non-blocking standard i/o function achieve functionality.

so i'm not sending arguments, setting class variable value, using again in method. "best practice" way things? if not, i'd interested in learning correct way. thanks! can/should arguments sent other way? private string printthis; public void printit(string input){ printthis = input; //setting printthis here static private printdocument pd = new printdocument(); pd.printpage += new printpageeventhandler(printdocument_printsomething); pd.print(); } private void printdocument_printsomething(object sender, printpageeventargs e) { e.graphics.drawstring(printthis, new font("courier new", 12), brushes.black, 0, 0); //using printthis in above line } closures introduced language solve problem. by capturing appropriate variable, can give storage 'outlives' containing method: // note 'input' variable captured lambda. pd.printpage += (sender, e) => print(e.graphics, input); ... static void print(graphic...

i have web page has function send initial request web service. after predefined time, user can send second request. after user sends first request, want web page countdown when user may send second request. after countdown, want db field updated automatically, indicating appropriate time has passed. when time has passed , db updated, i'd webpage updated show button allow user send second request. after initial request, call javascript user-defined function " countdown() " using in-built javascript function " settimeout("countdown()", 4000) ", number " 4000 " resembles number of micro-seconds need passed fire function mentioned in first parameter. in " countdown() " function, write logic ajax call, updating database desired time of 4 seconds (for example) has passed & user can send second request. also in same ajax call, can print out word (let word " yes " example), can catch / fetch in " countd...

in cakephp app have static pages set this: router::connect( '/terms', array('controller' => 'pages', 'action' => 'display', 'terms') ); this rewrite /terms /pages/display/terms make prettier shorter urls. now if wanted static pages, quite redundant: router::connect( '/terms', array('controller' => 'pages', 'action' => 'display', 'terms') ); router::connect( '/privacy', array('controller' => 'pages', 'action' => 'display', 'privacy') ); router::connect( '/about', array('controller' => 'pages', 'action' => 'display', 'about') ); with regular mod_rewrite can this: /(terms|privacy|about) /pages/display/$1 so naturally attempted this: router::connect( '/(terms|privacy|about)', array('controller' =...

i'm writing tcp server online turn-based game. i've written prototype using php sockets, move c++. i've been looking @ popular network libraries (asio, ace, poco, libevent), unclear 1 best suit needs: 1) connections persistent (on order of minutes), , server must able handle 100+ simultaneous connections. 2) connections must able maintain state information (user login info). [my php prototype requires each client request contain login info] 3) optionally , preferably multi-threaded, single process. prefer not have 1 thread per connection, fixed number of threads working on open connections. i'm leaning towards poco's tcpserver or reactor frameworks, not sure if meet requirements. think reactor single threaded, , tcpserver enforces 1:1 threading/connection. correct? in either case case, i'm not sure how important task of associating login info specific connection connections coming , going @ random. boost.asio should meet requirements. ...

could tell me, why wrong? i have mytype test[2]; stringsstream result; int value; (int i=0; i<2; i++) { result.str(""); (some calculating); result<< value; result>> test[i]; } when watch test array - first - test[0] - has correct value - every other test[1..x] has value 0 why wrong , not working? in first run in cycle stringstream set correct value array, later there 0? thanks try result.clear() ing stringstream before flushing result.str("") . sets state of accepting inputs again after outputting buffer. #include <sstream> using namespace std; int main(){ int test[2]; stringstream result; int value; (int i=0; i<2; i++) { result.clear(); result.str(""); value = i; result<< value; result>> test[i]; } return 0; } without clearing test[0] == 0 , test[1] == -832551553 /*some random number*/ . clear expected output of te...

i trying play video in 1 of screens. seems run when file opens, fullscreen loads , closes right after. video few seconds long, , m4v format. added framework , imported class. how can make video plays properly? my header: -(ibaction)playmedia:(id)sender { nsstring *moviefile; mpmovieplayercontroller *movieplayer; moviefile = [[nsbundle mainbundle] pathforresource:@"movie" oftype:@"m4v"]; movieplayer = [[mpmovieplayercontroller alloc] initwithcontenturl: [nsurl fileurlwithpath: moviefile]]; [movieplayer.view setframe:cgrectmake(145.0, 20.0, 155.0 , 100.0)]; [self.view addsubview:movieplayer.view ]; [[nsnotificationcenter defaultcenter] addobserver:self selector:@selector(playmediafinished:) name:mpmovieplayerplaybackdidfinishnotification object:movieplayer]; [movieplayer play]; if ([togglefullscreen ison]) { [movieplayer setfulls...

i have web form textbox , button. want after "enter" key click on textbox postbak form. i using next code: onkeypress=" if(event.keycode==13) { alert(2); webform_dopostbackwithoptions(new webform_postbackoptions('ctl00$contentplaceholder1$btnsearch', '', true, '', '', false, false)); alert(2); return false;} where webform_dopostbackwithoptions(new webform_postbackoptions('ctl00$contentplaceholder1$btnsearch', '', true, '', '', false, false)); is javascript code button event onclick. i 2 alerts, postback doesnot happen. any ideas wrong? asp.net creates client side javascript method __dopostback support postback. example: __dopostback('__page', 'mycustomargument');

i have tried this: public static class listhelper { public static string tostring<t>(this ilist<string> list) { return string.join(", ", list.toarray()); } public static string tostring<t>(this string[] array) { return string.join(", ", array); } } but not work, both string[] , list<string> . maybe need special annotations? extension methods checked if there no applicable candidate methods match. in case of call tostring() there always applicable candidate method, namely, tostring() on object . purpose of extension methods extend set of methods available on type, not override existing methods; that's why they're called "extension methods". if want override existing method you'll have make overriding method.
