this thinking comes discussion practical problem replacing multiple new lines in file one . wrong happened while using cygwin terminal running on windows 8.1 machine. since end-of-line terminator different, \n , \r , or \r\n , necessary write "portable" if(c=='\n') make work on linux, windows , os x? or, the best practise convert file commands/tools? #include <stdio.h> int main () { file * pfile; int c; int n = 0; pfile=fopen ("myfile.txt","r"); if (pfile==null) perror ("error opening file"); else { { c = fgetc (pfile); if (c == '\n') n++; // work fine under different platform? } while (c != eof); fclose (pfile); printf ("the file contains %d lines.\n",n); } return 0; } update1: crt convert line endings '\n'? if input file opened in binary mode (the character 'b...

i want animate views (based on tag) alpha change, getting "cannot assign alpha view" error. way this? all views have alpha of 0 upon being added subview of mycustomview func transitioneffects() { uiview.animatewithduration(0.5, animations: { view in self.mycustomview.subviews { if(view.tag != 999) { view.alpha = 1 } } }) } this because swift needs know kind of objects inside subviews nsarray before sending methods. nsarray automatically converted in swift array of anytype objects, doesn't know kind of objects extracted array. casting array array of uiview s objects should work fine. func transitioneffects() { uiview.animatewithduration(0.5, animations: { view in self.mycustomview.subviews [uiview] { if(view.tag != 999) { view.alpha = 1 } } }) }

i work on avx2 , need calculate 64-bit x64-bit -> 128-bit widening multiplication , got 64-bit high part in fastest manner. since avx2 has not such instruction, reasonable me use karatsuba algorithm efficiency , gaining speed? no. on modern architectures crossover @ karatsuba beats schoolbook multiplication somewhere between 8 , 24 machine words (e.g. between 512 , 1536 bits on x86_64). fixed sizes, threshold @ smaller end of range, , new adcx/adox instructions bring in further scalar code, 64x64 still small benefit karatsuba.

i'm building game , i'm supporting following texture formats: atc dxt png pvr i'd add support etc2 (etc1 won't work because of our graphics require alpha channel). cocos2d-x support etc2 textures? no. but 2 things. cocos2d-x doesn't have etc2 defines in cctexture2d.h. need add etc2 defines yourself. https://github.com/cocos2d/cocos2d-x/blob/v4-develop/cocos/renderer/cctexture2d.h#l95-l96 https://github.com/cocos2d/cocos2d-x/blob/v4-develop/cocos/renderer/cctexture2d.cpp#l60-l110 //! 2-bit pvrtc-compressed texture: pvrtc2 (has alpha channel) pvrtc2a, //! etc-compressed texture: etc etc, //! s3tc-compressed texture: s3tc_dxt1 s3tc_dxt1, and cocos2d-x uses opengl es 2.0 context, @ least, on android. https://github.com/cocos2d/cocos2d-x/blob/v4-develop/cocos/platform/android/java/src/org/cocos2dx/lib/cocos2dxglsurfaceview.java#l76 this.seteglcontextclientversion(2); so using etc2 glcompressedteximage2d needs these extensions. o...
