hopefully job asking question... my web host (webfaction) contacted me , said 1 of sites i'm hosting using many resources shared mysql pool. said should create private mysql instance on application server , run things there not impact other sites. an understandably fair , reasonable request. i've gone ahead , created private instance database have one-click installer. can tell has no phpmyadmin, , i've never worked "private instance" db before have questions... being 95% wordpress user have have private instance db every wordpress site host, or can 1 handle needs of many? if later...how ()? i absolutely refuse ssh db make changes. i've never done before, don't know syntax, , scares hell out of me truthfully. there app/tool (i'm mac user) makes interacting private instance db simple , easy? i've been looking sequel pro i'm not sure. again, hope way asked isn't confusing. yes, can handle lots of wordpress instances si...

i have pretty simple application nuget references , works fine locally. have not committed packages folder of course, config. when have teamcity build solution, got error needed enable nuget package restore did. now when build message the build restored nuget packages. build project again include these packages in build. more information, see http://go.microsoft.com/fwlink/?linkid=317568 . makes sense, error no matter how many times build it. continually fails. missing here? run nuget package restore before build solution. team city should have nuget installer step restore nuget packages. add build steps before compilation of solution. you build step runs: nuget.exe restore yoursolution.sln however team city's built in nuget build step allows configure other things, such private nuget repository urls, easier creating own build step scratch.

i designing game in python , know how make efficient timer can run along side game. note: using pygame. i have timer so: import time seconds = 60 def start_timer(): global seconds while seconds > 0: print seconds seconds -= 1 time.sleep(1) however, when run in main game function game hangs because of timer.sleep . def main(self): timer.start_timer() i'm pretty sure issue has not using threading, although i'm not 100% sure. can explain me proper solution is? if you're using pygame, has own time functionality should using. if you're using event-loop or hybrid design, loop on pygame.event.get() or similar , call "event handlers" different events mouse-click or key-down, can use set_timer create event fires every second. example: timer1_event = pygame.userevent + 1 def start_timer1(): global seconds seconds = 60 pygame.time.set_timer(timer1_event, 1000) def on_timer1(): glob...

this question might pretty simple still can't figure out efficient way this. have following setup: 1) thread downloads data internet memory buffer. 2) @ same time, thread b wants read data has been downloaded buffer. the buffer not circular or anything. there write cursor , read cursor. once thread has written buffer, updates write cursor tell thread b how data available reading. the problem thread b reads thousands of bytes in steps of single byte @ time. need efficient way of synchronizing 2 threads. i've tried setevent() , waitforsingleobject() seems quite slow (or did wrong) because thread b reading in packets of 1 byte buffer thread b has call waitforsingleobject() every byte needs read. sounds lot of overhead. shouldn't possible without mutex (critical section) protection? i.e. thread b poll write cursor until enough data available , copy it. question of synchronization comes up, i.e. when thread updates write cursor, change reflected in thread b? don...

i have linux program sends & receives udp packets (it interacting various remote machines according protocol). "inject" additional udp packets second program return address ip/port used main program. for example, imagine main program sending "ping" style udp packets various remote hosts, , send "pong" packets. injector program send ping somewhere, , have main program receive pong. (the main program wouldn't expecting pong, because didn't send out ping, that's ok.) a complex way have main program accept injected packets local pipe or , send them out. easier if injector set "from" address on sendto() packet. (i don't want injector steal packets meant main program. injector short-lived, if bound main program's port, theoretically system deliver pongs instead of main program?)

i'm attempting create program given n, need q = 0...n. so if given n = 1: q = 0. if given n = 5: q = 0, q = 1,...,q = 4 my attempt far: values(n,q) :- values_helper(0,n,q). values_helper(n, n, q). values_helper(x,n,q) :- x0 x + 1, x0 < n, values_helper(x0,n,x0). my logic behind increment x until reaches value of n, @ point program stops. however, i'm not getting bindings q, empty set. know i'm neglecting stop @ n - 1. edit: fixed ambiguities description. both of values_helper clauses don't expect. first 1 succeeds if first 2 arguments same, , doesn't impose constraints on q. want q set equal first argument, long it's smaller second argument: values_helper(q, n, q) :- q < n. in second clause, again don't use q anywhere. recursive call should values_helper(x0, n, q) , giving: values_helper(x, n, q) :- x0 x + 1, x0 < n, values_helper(x0, n, q). these clauses give expected output: ?- values(5,q). ...

i need regex pattern max length 12 , should not accept 0 if entered user. my current pattern not working. here is: [0-9]{0,12} any suggestions welcome , explanation of pattern. ^[1-9]{0,12}$ means 12 digits (excluding 0), left emtpy allowed. if field required, change minimun 1, ^[1-9]{1,12}$ and way, ^ , $ means start , end of input string. if regexp [1-9]{1,12} , without ^ , $ , "abc123def" allowed because center part 123 matched.

i'm building game build hashtable of words (a dictionary) , take 2 strings , int user. try permute first string second string. done permuted 1 letter @ time , putting new word tree structure child node holding original word. done until original word permuted second word or until number permutations exceeds int given user. in basic test case giving program cat , cot , 3 hops. doesn't work. i've tried several things @ point can't figure out more , can't more specific. here code public static void permute(hashtable dict, queue<tnode> nodes, arraylist<string> oldwords, string destination, int hops, int hopcounter) { char[] alphabet = { 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', //array every letter in alphabet used permutations 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't...
