qstring has few methods such toint(), tolong(), etc. these methods receive pointer bool determines if conversion successful shown here: int qstring::toint(bool * ok = 0, int base = 10) const my question is: why 'ok' pointer , not reference? i know implemented using either, don't see advantage of using pointer on reference. i know implemented using either, don't see advantage of using pointer on reference. you use reference default value int qstring::toint(bool& ok = some_bool_guaranteed_by_the_library, int base = 10) const; the downside of library has provide some_bool_guaranteed_by_the_library globally available bool object. sounds designers of library did not see enough benefits provide such object.

i beginner java programming, , write program http request in every minute. and try build jar , run on cmd, because want run few java in same time. see it’s memory consuming higher run on ide. , program have lot of console output. and lot of people told me use multi thread finish work, research said multi thread when process loading switch other process load, multi thread real multi tasking? because in future maybe http request every 5 second , want real multi tasking function. thanks everyone, , sorry bad english . p.s. using intellij community version memory consumption: lange amounts of console output can influence memory usage. the command line , ide handle console output differently (e.g. buffer size). you should ask yourself: do need console output? furthermore it's possible ide uses different commandline paramater start jvm (e.g. heap size) multithreading: before use multiple threads should ask 1 question: does program benefit multithreading...

i looking standard python 2.7 package providing http server simultaneous streaming connections on same port number. hey moderators out there, please stop flagging question duplicate of questions want serve in non-streaming ways, one: multithreaded web server in python . no, don't want hack such threadingmixin merely collects response , returns unit. in other words, i'm looking standard way following example program -- without writing whole http server myself. import time, socket, threading sock = socket.socket (socket.af_inet, socket.sock_stream) host = socket.gethostname() port = 8000 sock.bind((host, port)) sock.listen(1) # own http server... oh man, bad style. http = "http/1.1 200 ok\ncontent-type: text/html; charset=utf-8\n\n" class listener(threading.thread): def __init__(self): threading.thread.__init__(self) self.daemon = true # stop python biting ctrl-c self.start() def run(self): conn, addr = sock.acc...

i've been using pulp library side project (daily fantasy sports) optimize projected value of lineup based on series of constraints. i've implemented of them, 1 constraint players must come @ least 3 separate teams. this paper has implementation (page 18, 4.2), i've attached image: it seems somehow derive indicator variable each team that's 1 if given team has @ least 1 player in lineup, , constrains sum of indicators greater or equal 3. does know how implemented in pulp ? similar examples helpful. any assistance super appreciated! in case define binary variable t sets upper limit of x variables. in python don't name variables single letter have nothing else go on here how in pulp. assume variables lineups , players , players_by_team , teams set somewhere else x_index = [i,p in lineups p in players] t_index = [i,t in lineups t in teams] x = lpvariable.dicts("x", x_index, lowbound=0) t = lpvariable.dicts("t...
