i have program, in c, creates array of 1000 integers using random number 0-999 , performs sort of algorithm on array. in order test algorithm's running time, try running program 10000 times, every time run array same few arrays , changes. have used srand() function feed seed current time, still not help. is there alternative solution rand() or way fix this? function is: void getarray(int *ptr1,int size,int option){ int n; srand(time(null)); for(n=0; n<size;n++) *(ptr1+n) = *(ptr2+n)= rand()%1000; } thanks in advance! you should call srand once: on program startup. right now, if call function multiple times before time changes sequence same.

i've implemented probabilistic roadmap method function, works , executes correctly. problem output of prm not smooth example, if hand needs rotate 30 100 degrees, steps might 30,55,42,66,99,100, wat able smoothen transition betwen 30 , 100 degree. know problem related tp smoothing of signal yet dont know type of smoothing might able job. no sophisticated method needed. implementation in c#, if possible wish let such job done library. there such library? can give array of integers , likewise produce array of smoothed values. i think need simple curve fitting algorithm. quick google search give lots of example code. , if want have strictly increasing curve, need sort values before curve fitting. if interested in reaching target, can drop values in between , linear interpolation start end or similar.

is appropriate server return 503 ("service unavailable") when requested operation resulted in database deadlock? here reasoning: initially tried avoiding database deadlocks, ran across https://stackoverflow.com/a/112256/14731 next, tried repeating request on server-side, ran across java servlets: how repeat http request? . technically speaking can buffer request entity scalability suffer , clients more see 503 service unavailable anyway. seeing as: it's easier ask clients repeat operation. they need able handle 503 service unavailable anyway. database deadlocks rather rare. i'm leaning towards solution. think? update : think returning 503 ("service unavailable") still acceptable if wish it, no longer think technically required. see https://stackoverflow.com/a/17960047/14731 . i think it's fine long entire transaction rolled or if request idempotent.

i have function read text file following format string int int string int int string int int i want write function assign values text file variables, there cases format of text file be string int string int string int in case, i'd set value of last int variable 1. code have far works first example i'm bit stuck on getting second scenario work: void readfile(linkedlist *inlist, char* file) { char tempname[30]; int temploc, tempnum; file* f; f = fopen(file, "r"); if(f==null) { printf("error: not open file"); } else { while (fscanf(f, "%s %d %d\n", tempname, &temploc, &tempnum) != eof) { insertfirst (inlist, tempname, temploc, tempnum); } } } in second case, fscanf return 2 instead of 3. can rewrite code this: while (1) { int ret = fscanf(f, "%s %d %d\n", tempname, &temploc, ...

i'm trying find specific string command output in terminal. doesn't work however. here command i'm running: check = subprocess.check_output("netctl list | sed -n 's/^\* //p'", shell=true) that brings 1 of 2 things. if not connected, returns b'', otherwise returns b'$networkname\n'. the code i'm using check follows: p = re.compile(r"\bb''\b") if p.search("b''"): print("false") return false else: print("true") return true however, returns true no matter what. i've tried: if check == "b''": but returns true no matter what. i'm losing mind here. causing not work? thanks in advance, cody the fact should looking empty bytes literal b'' , not string "b''" . if check == b'':

i pick file angularjs: html: <div ng-controller="topmenuctrl"> <button class="btn" ng-click="iscollapsed = !iscollapsed">toggle collapse</button> <input type="file" ng-model="filepick" ng-change="pickimg()" multiple /> <output id="list"></output> </div> javascript: angular.module('plunker', ['ui.bootstrap']); function topmenuctrl($scope) { $scope.pickimg = function() { alert('a'); }; } how can bind input file onchange action on angularjs pickimg function? , how can manipulate files uploaded after? angular doesn't yet support ng-change input[type=file] have roll onchange implementation yourself. first, in html, define javascript onchange follows: <input ng-model="photo" onchange="angular.element(this).scope().file_changed(this)" type="file" acc...

i'm experienced obj-c/java programmer, , getting ruby. fact it's dynamic great (re-opening classes awesome!) there's 1 thing bugs me/worries me when start writing ruby code. i'd interested know ruby-ers (if anything) explicitly set type of ivars in own classes. can see, can set ivar object , ruby won't complain. if expect specific ivar of type, can cause problems down line. example: class mystring def initialize(mystring) @mystring = mystring end def uppercase_my_string @mystring.upcase end end st1 = mystring.new("a string!") st1.uppercase_my_string st2 = mystring.new(["a string"]) st2.uppercase_my_string this code throw nomethoderror , since of course array has no method upcase . unfortunately doesn't tell went wrong (the line above, when creating str2 ) we're not helped when debugging (if str2 happens created several modules away in inconspicuous place) 1 natural step might add checks initialize follows: ...
