i'm interested in scenario document fetched database, computations run based on external conditions, 1 of fields of document gets updated , document gets saved, in system might have concurrent threads accessing db. to make easier understand, here's simplistic example. suppose have following document: { ... items_average: 1234, last_10_items: [10,2187,2133, ...] ... } suppose new item (x) comes in, 5 things need done: read document db remove first (oldest) item in last_10_items add x end of array re-compute average* , save in items_average . write document db * note: average computation chosen simple example, question should take account more complex operations based on data existing in document , on new data (i.e. not solvable $inc operator) this easy implement in single-threaded system, in concurrent system, if 2 threads follow above steps, inconsistencies might occur since both update last_10_items , items_average values without considerin...

how calculate mse rgb , grayscale image in matlab? have written code here: i = imread('iris.jpg); gray = rgb2gray(i); n = size(i); m = n(1); n = n(2); mse = sum(sum(i-gray).^2))/(m*n); fprintf('\nmse:%7.2f',mse); however, when run code, error: error using - matrix dimension must agree. how fix error? i'm not sure why you'd want this.... since grayscale , colour images different each other in terms of colour values. the error you're getting quite clear. grayscale image has 1 channel while rgb image has three. trying subtract images of incompatible dimensions , error. however, if mse calculation want, need make sure grayscale image has 3 colour channels. grayscale images have red, green , blue components equal, , simple fix repmat should trick. can use duplicate grayscale image on multiple channels simulate colour image. do gray variable before computing mse: gray = repmat(gray, [1 1 3]); as such, doing this. btw there typo in...

i'm beginner in javascript/jquery, etc. , i'm facing little problem maybe me solve. have object prototype name page , in there array , function ajax post , process answer. code looks this: function page( url ){ this.url = url; this.elarr = []; this.addelem = function( elem ){ this.elarr.push( elem ); } this.job = function(){ $.post( this.url, { // data here... }, function( data, status ){ var decodeddata = json.parse( data ); this.elarr[0].value = decodeddata.value; // error: elarr not defined }); } }; i like: var page = new page( 'page.php' ); page.addelem( new elem ); elem prototype .value . the php code on server side answers correctly post request. using chrome development tools, can step javascript code , decoded json answer correct. problem arises when tries access this.elarr[0] (yes, in page1, elarr[0] exists!) ex...

i using pm2 version 0.12.9 i start app using command: pm2 start bin/www --name gototravel --log-date-format="yyyy-mm-dd hh:mm z" then query pm2 logs ll ~/.pm2/logs -rw-rw-r-- 1 wucho wucho 0 may 12 11:03 gototravel-error-0.log -rw-rw-r-- 1 wucho wucho 1822 may 12 11:03 gototravel-out-0.log my first question don't see log file prefixed timestamp. then run pm2 reloadlogs and query pm2 logs,but no log generated ll ~/.pm2/logs -rw-rw-r-- 1 wucho wucho 0 may 12 11:03 gototravel-error-0.log -rw-rw-r-- 1 wucho wucho 1822 may 12 11:03 gototravel-out-0.log i nodejs newbee , give me suggestions? s --log-date-format prefix entries in log files, not prefix log file names. reloadlogs doesn't rotate logs you. causes log file recreated if it's been rotated out under program process.

i've seen questions here related error such this , this , know can't execute imgproc.matchtemplate() method if image , template don't have same datatype. i'm still confused on how know type of mat i'm using. below code adapted example here : for (int = 0; < 24; i++) { arrdraw[i] = getresources().getidentifier("let" + i, "drawable", getpackagename()); } mat mimage = input.submat(bigrect); (int = 0; < 24; i++) { mat mtemplate = utils.loadresource(this, arrdraw[i], highgui.cv_load_image_color); mat mresult = new mat(mimage.rows(), mimage.cols(), cvtype.cv_32fc1); imgproc.matchtemplate(mimage, mtemplate, mresult, match_method); core.normalize(mresult, mresult, 0, 1, core.norm_minmax, -1, new mat()); ... // further process } so i'm trying take mimage submat of inputframe , match template process 24 other pictures , decide has best value (either lowest or highest). yet error shows this. opencv error:...
