it looks there 2 mainstream solutions instructing crawlers index , not index: adding x-robot-tag http header, or indicating robots.txt. is there advantage using former? with robots.txt cannot disallow indexing of documents. they have different purposes: robots.txt can disallow crawling (with disallow ) x-robots-tag ¹ can disallow indexing (with noindex ) (and both offer additional different features, e.g., linking sitemap in robots.txt , disallowing following links in x-robots-tag , , many more.) crawling means accessing document. indexing means providing link (and possibly metadata or about) document in index. in typical case, bot indexes document after having crawled it, that’s not necessary. a bot isn’t allowed crawl document may still index (without ever accessing it). bot isn’t allowed index document may still crawl it. you can’t disallow both . ¹ note header called x-robots-tag , not x-robot-tag . way, metadata name robots (for html meta e...

so have matrix m=(50,50,250) , want fft2 of slices s=(50,50) along 3rd dimension = 250. let's ft = fftshift(fft2(m)); is calculating ft want? because in function description says function returns 2-d dft each higher dimensional slice of x. example, if size(x) = [100 100 3], fft2 computes dft of x(:,:,1), x(:,:,2) , x(:,:,3) . so, assuming computing ft of slices s=(50x250) along 1st dimension = 50. can clear me? i think quite clear documentation. fft2 computes 250 2d dfts, 1 each of 50x50 slices in m. ft(:, :, i) 2d dft of m(:, :, i). behaves same as: ft = zeros(size(m)); = 1 : size(m, 3) ft(:, :, i) = fft2(m(:, :, i)); end you verify follows ( error should small): ft1 = fft2(m); error = norm(abs(ft1(:) - ft(:))); however, behavior of fftshift not consistent want. should instead use second argument of fftshift shift result along specific dimensions (1 , 2 in case): ft = fftshift(fftshift(fft2(m), 1), 2);

the following small program ( online version ) attempts calculate area of 64 64 square recursively dividing 4 squares until smallest square has unit length (hardly optimal). reason program hangs. doing wrong? #include <iostream> unsigned compute( unsigned length ) { if( length == 1 ) return length * length; unsigned a[4] , area = 0 , len = length/2; for( unsigned = 0; < 4; ++i ) { #pragma omp task { a[i] = compute( len ); } #pragma omp single { area += a[i]; } } return area; } int main() { unsigned area , length = 64; #pragma omp parallel { area = compute( length ); } std::cout << area << std::endl; } the single construct acts implicit barrier threads in team. however, not threads in team encounter single block, because different threads working @ different recursion depths. why application hangs. in case code not cor...

i have following function converts query string moment (or date) object. i've run bunch of tests , basically moment.js doesn't seem accept req.query.m valid string . moment works fine if hardcode input, , i'm able query string itself. the query string is: http://localhost:8080/file/newcalendar?m=1455910939 app.get('/file/newcalendar', function(req, res) { var dateselect = req.query.m; var selecteddate = moment(req.query.m); var selectedmonth = selecteddate.month(); jsontest = { 'testquery': dateselect, 'testmomentonquery': moment(req.query.m), 'testmomentonvariable': moment(dateselect), 'testmomentmonth': moment(12345678).month(), }; res.json(jsontest); }) i've tried using date() instead of moment. app.get('/file/newcalendar', function(req, res) { var selecteddate = date(req.query.m); var selectedmonth = selecteddate.getmonth(); jsontest = { ...

i have variable in php, , need value in javascript code. how can variable php javascript? i have code looks this: <?php ... $val = $myservice->getvalue(); // makes api , db call ?> i have javascript code needs val , looks along lines of: <script> myplugin.start($val); // tried this, didn't work <?php myplugin.start($val); ?> // didn't work either myplugin.start(<?=$val?> // works sometimes, fails </script> there several approaches this. require more overhead others, , considered better others. in no particular order: use ajax data need server. echo data page somewhere, , use javascript information dom. echo data directly javascript. in post, we'll examine each of above methods, , see pros , cons of each, how implement them. 1. use ajax data need server this method considered best, because your server side , client side scripts separate . pros better separation between layers - i...

i've started learn php classes, interfaces, extends , things related those. before i've worked functions , started quite mess hundreads of separate functions. there multiple classes project based on needs: cart class. should quite generic because @ point might need save data database instead of sessions. calculations class. there around 15 products , around 5 different type of calculations. (based on amount, base price, price per person etc.) database class. used prices database calculations class. create pdf mpdf submitted data through html form (which used update cart amounts , return calculated prices in real time) however, give hint on i'm trying achieve, might give better understanding on how should approach things. now actual questions. here's cart class: interface cartinterface { public function additem($id, $amount, $months); public function updateitem($id, $amount, $months); public function deleteitem($id); public function c...
