[edit] redirect stdio, replace sys.stdout/sys.stderr buffers or else supports "write()". to restore original values, sys module offers __stdout__ , etc. [edit2] haven't tried might work: add together "python.exe" set of files py2exe creates. from main code, re-create files py2exe created + python.exe temporary direct...

c++ - How can I find out how many bytes are available from a std::istream? - if wanted read() content of std::istream in buffer, have find out how much info available first know how big create buffer. , number of available bytes istream, doing this: std::streamsize available( std::istream &is ) { std::streampos pos = is.tellg(); is.seekg( 0, std::ios::end ); std::streamsize len = is.tellg() - pos; is.seekg( pos ); homecoming len; } and similarly, since std::istream::eof() isn't useful fundtion afaict, find out if istream 's pointer @ end of stream, i'm doing this: bool at_eof( std::istream &is ) { homecoming available( ) == 0; } my question: is there improve way of getting number of available bytes istream ? if not in standard library, in boost, perhaps? for std::cin don't need worry buffering because buffered --- , can't predict how many keys user strokes. for opened binary std::ifstream , buffere...

java - design a test program: increase/decrease cpu usage - i trying design , write java programme can increase/decrease cpu usage. here basic idea: write multi-thread program. , each thread float point calculation. increase/decrease cpu usage through adding/reducing threads. i not sure kinds of float point operations best in test case. especially, gonna test vmware virtual machine. you can sum reciprocals of natural numbers. since sum doesn't converge, compiler not dare optimize away. create sure result somehow used in end. 1/1 + 1/2 + 1/3 + 1/4 + 1/5 ... this of course of study occupy floating point unit, not central processing unit. if approach or not main question should pose. java design testing implementation

Fastest way to calculate the size of an file opened inside the code (PHP) - i know there quite bit of in-built functions available in php size of file, of them are: filesize, stat, ftell, etc. my question lies around ftell quite interesting, returns integer value of file-pointer file. is possible size of file using ftell function? if yes, tell me how? scenario: system (code) opens existing file mode "a" append contents. file pointer points end of line. system updates content file. system uses ftell calculate size of file. fstat determines file size without acrobatics: $f = fopen('file', 'r+'); $stat = fstat($f); $size = $stat['size']; ftell can not used when file has been opened append( "a" ) flag. also, have seek end of file fseek($f, 0, seek_end) first. php file filesize
