i know source insight can show multilayer function relationship in 1 window. for example, have 4 functions below void example_a() { example_b(); } void example_b() { example_c(); } void example_c() { example_d(); } void example_d(); { return 5; } when click example_d() in source insight, source insight show example_c() calling function. moreover, when click example_c() , see example_b() calling function. the relationship this: example_d() | -->example_c() | -->example_b() | -->example_a() could see relationship in 1 window using cscope in vim? thank you. cctree plugin vim kind of visualization using cscope https://sites.google.com/site/vimcctree/ http://www.vim.org/scripts/script.php?script_id=2368 https://github.com/hari-rangarajan/cctree

the feature i'm after able tell gradient of given variable respect error function given data. one way see how variable has changed after call train, can vary massively based on learning algorithm (for example impossible tell rprop) , isn't clean. thanks in advance. the tf.gradients() function allows compute symbolic gradient of 1 tensor respect 1 or more other tensors—including variables. consider following simple example: data = tf.placeholder(tf.float32) var = tf.variable(...) # must tf.float32 or tf.float64 variable. loss = some_function_of(var, data) # some_function_of() returns `tensor`. var_grad = tf.gradients(loss, [var])[0] you can use symbolic gradient compute numerical gradient particular data: sess = tf.session() var_grad_val = sess.run(var_grad, feed_dict={data: ...})

situation: a pyro4 server gives pyro4 client pyro4 proxy. i want detect whether client still indeed using proxy, server can give proxy other clients. my idea @ moment have server periodically ping client. this, client need host pyro daemon, , give server pyro4 proxy server can use proxy ping clients. is there cleaner way this? i'd let client report server no longer needs proxy. i.e. don't overcomplicate server dependencies/knowledge clients.

i making programme in java school project. has form of interactive multiple-choice test. i wanted perform in way action button creates event in (the order of code same listed): 1) randomly chooses object consist of several strings prepared list , prints on adequate text fields in gui 2) using proper method there delay created holds further code down below 1 minute. in time user should able check proper checkboxes gui must stay active. 3)when minute ends checked places read , further processed. the thing unable create step number 2) delaying of code below. have tried function sleep() when sleep() whole gui freezes , user unable on it. have read function swing timer appropriate dont know how it. have seen examples in them timer along functions executed after time written in class actionlistener instead of action button. using netbeans 8.1 sorry bad explanation of problem, total beginner in java programming , count on :) cheers! your problem comes how structure...

i know question quite silly, in interview told implement trim() method without using method string class except substring() method. i approached problem using tochararray() , identifying first , last valid character of string. told not use tochararray() method. could suggest approach it. overriden methods of objects class allowed equals() , hashcode(). string untrimmed = " string "; string trimmed = ""; string innerspaces = ""; boolean wordboundary = true; try { (int = 0; ; i++) { string substr = untrimmed.substring(i, + 1); if (!substr.equals(" ") && !substr.equals("\t") && !substr.equals("\n") && !substr.equals("\r")) { trimmed += innerspaces + substr; wordboundary = false; innerspaces = ""; } else if (!wordboundary) { innerspaces += substr; } ...

so created recyclerview , inflating xml file recyclerview, inside customxml file have checkbox, however, when click on checkbox gives me true statement first panel in recyclerview , rest false whats that? public void checkbox(view view) { final checkbox checkbox = (checkbox) findviewbyid(r.id.checkbox); if (checkbox.ischecked()) { system.out.println("set checked"); } else{ system.out.println("set unchecked"); } } note in recyclerview , multiple child views have same id . suspect final checkbox checkbox = (checkbox) findviewbyid(r.id.checkbox); not return checkbox want. sounds returns first 1 in list, not 1 clicked on. since checkbox() onclick listener checkboxes, there no reason call findviewbyid() . can use view sent parameter: checkbox checkbox = (checkbox)view;

what difference between using standard hanging parens method invoking function expression , using .call in javascript? i see iifes invoked like (function(){ //your code here }).call(this); as opposed more standard (function(){ //your code here })(); what advantage of using .call if any? it depends on scope. if in global scope, using .call(this) has absolutely 0 effect because this window object. if in nested scope somewhere, , want use thisbinding ( this ) using .call(this) important (or storing this in variable such self or that ). iife going executing @ global scope, this binding going change window . if attempt use this made in scope, , this isn't bound, referencing wrong object. here example: window.x = 5; (function(){ console.log(this.x);//5 })() var obj = { x : 6, test : function(){ (function(){ console.log(this.x);//5 })() }, close : function(){ (function()...

i trying detect numbers in sudoku grid using template image.i doing in matlab. example have cropped '1' image , need use image detect other '1' present in image. not going anywhere this. please me. ho you have choosen hardest number start with, because if use typical template matching approach (using xcorr2 , normxcorr2 , or conv2 ) you're going accidentally match horizontal , vertical lines upright part of 4's. to better demonstrate basic process, start number 7 since little bit more unique of shape. first want load images in grayscale (extract red channel) board = imread('board.jpg') board = board(:,:,1); template = imread('seven.jpg') template = template(:,:,1) in order detect template in image, can use normalized 2d cross-correlation . method shifts template on image , @ each shift computes correlation between template , image. c = normxcorr2(template, board); figure; imshow(c); as can see, correlation value...
