visual studio - VS2013, C++: Unknown "thread X exited with code 0" -

-

i developing qt application on vs2013. 1 day turned attention fact qt runtime libs perform strange cpu consumptive actions. firstly, decided occurs in qt debug libs , turned debug configuration use qt release libs. still confused when observing in vs output window, @ middle of debugging application, such prints: the thread 0xxxxx has exited code 0 (0x0). don't understand thread finished. how can detect thread hidden behind thread id = 0xxxxx once thread has finished?

update (clarification) in question meant: 1. possible information thread id appeared in such vs print 2. know qt may execute in such hidden threads?

different libraries may create worker threads various purposes.

if want investigate further following in vs ide:

  1. debug -> break all. stop threads in process
  2. debug -> windows -> threads list of threads.

by examining call stack of threads may idea of purpose.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl

python - PyCharm Type error Message -

i'm newbie trying out ml/dbn in python (3.4) under pycharm (comm.ed 4.5). following definition def make_thetas(xmin,xmax,n): xs = np.linespace(xmin,xmax,n) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1] + widths return thetas throws error "class 'tuple' not define ' sub ', '-' operator cannot used on instance" on - operator on third line (widths = ....) ideas on how code running under pycharm - works alright in interactive python window. thx. to all, after g'g lot have found workaround seems work within pycharm. workaround because (even python newbie) expected python not need explicit typecasting, not when using datatypes imported lib such numpy. def make_thetas(xmin,xmax,n): xs = np.array(np.linspace(xmin,xmax,n)) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1]+ widths return thetas using docstrings type-hinting such below did not work def make_thetas(xmin,xmax,n): "&q
