so question regarding use of reshape , how functions uses each axis on multidimensional scale . suppose have following array contains matrices indexed first index. what want achieve instead index columns of each matrix first index . in order illustrate problem, consider following example given numpy array indexes matrices first index z. x = np.arange(9).reshape((3, 3)) y = np.arange(9, 18).reshape((3, 3)) z = np.dstack((x, y)).t where z looks like: array([[[ 0, 3, 6], [ 1, 4, 7], [ 2, 5, 8]], [[ 9, 12, 15], [10, 13, 16], [11, 14, 17]]]) and shape (2, 3, 3) . here, first index 2 images , 3 x 3 matrix. the question more phrased then, how use reshape obtain following desired output : array([[ 0, 1, 2], [ 3, 4, 5], [ 6, 7, 8], [ 9, 10, 11], [12, 13, 14], [15, 16, 17]]) whose shape (6, 3) . achieves dimension of array indexes columns of matrix x , y presented above. natural inclination use reshape directly on z in followin...

i read lot difference between cisc , risc architectures different sources. 1 of things seemed agreed upon cisc used von neumann whereas risc used harvard architecture. couldn't quite grasp reason behind classification. there no relations between instruction set ( risc , cisc ) architecture of processor ( harvard architecture , von neumann architecture ). both instruction set can used of architecture. older arm architecture used von neumann architecture risc, , later arm9 shifted harvard architecture risc. latest arm processor uses more advanced hybrid architecture.

what method refresh route in angular 2 programatically in order trigger oninit hook? maybe there single method refresh current route. from: https://angular.io/docs/ts/latest/api/router/router-class.html renavigate() : promise<any> navigates either last url navigated to, or last url requested if router has yet navigate. inject router , call renavigate() method: this._router.renavigate();

we writing html 5 app requires large files loaded. we loading binary data files via ajax. app crashes on ipad. upon further investigation instruments on mac noticed while downloading file, memory allocated webkit exponentially grows runs out of memory. (100mb file grows memory on 550mb browser crashes) we tested loading kinds of other types of files via other methods such image obj shown below. function testimage() { var download = new image(); download.src = 'data/33mb.jpg?n=' + new date().gettime(); } after above 33mb image loads, instruments show memory has grown 309 mb. and here sample xhr call same results loading large binary file. function testxhr() { var xhr = new xmlhttprequest(); xhr.open('get', 'data/100mb.bin?n=' + new date().gettime()); xhr.send(); } we baffled happening. how load large files on safari mobile? any insight appreciated. in advance.
