javascript - Refresh webpage on change in folder -


i want refresh web page every time file uploaded folder.

i have web service written in flask having following handler

@app.route('/getlatest/') def getlatest():     import os     import glob     newset = max(glob.iglob('static/*'),key=os.path.getctime)     return newest;

this gives me name of latest file in folder.

i have ajax call in js (client side) data above function.

function getlatest()             {                 $.ajax({                     url: "http://localhost:5000/getlatest",                      success: function(result)                     {                         if(previousname != result){                             previousname = result;                             $("#image").attr("src","/"+previousname);                         }                     }                 });             }

function calling server every second.

(function myloop (i) {               settimeout(function () {        getlatest();                              if (--i) myloop(i);        }, 1000) })(100);

this works fine [well almost]. my question is: there better way it[ there must ]?

i'm open technology choices every may [node, angualr etc.]

yea can use websockets(flask-socketio).that let have open connection between , server , every time in folder new photo displayed on selected div

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
