i using doxygen document huge projects written in c#. existing documentation in these projects should not changed. is there way extend existing documentation , provide doxygen commands classes or methods in separate file? for example, lets there class viewmodel.cs, documented this: /// <summary> /// defines viewmodel can bound treelist control. /// </summary> public abstract class viewmodel : iviewmodel { /// <summary> /// gets root elements displayed in treelist. /// </summary> public observablecollection<itreenode> elements { get; protected set; } } is there way create separate file (.dox) linked class , extends existing documentation? e.g. group class specific module \ingroup command. to knowledge, no such tool exists. c# uses assemblies , namespaces conceptual grouping of apis. defining manual grouping separately serve confuse users familiar language. for best results, should use c# documentation comments along la...

i'm creating application render image offscreen , need read depth buffer. pc version of application easy, since can use glgetteximage or glreadpixels (using gl_depth_component). need port application android, have issues, since gl es not support glgetteximage @ all, , glreadpixel can used read color buffer (as understood). many people suggest render depth buffer color buffer (or render depth value color buffer), understand, glreadpixel can read 8 bit per channel values, , need @ least 16 bit per depth values. my target android device supporting opengl es, reading pixel buffer object, seams pbos faster method of transferring data gpu, read depth map still need use glreadpixels transfer depth map pbo (which not possible). i thinking maybe creating eglimage (wrappening own buffer) , use depth texture in fbo might solution, don't have experience eglimages, i'm not sure if possible or not (and work on android, need have different implementations pc , android). so, be...

when using :require in clojure or clojurescript, when should use aliases , when should cherry-pick functions use? examples: using alias (:require [some-package.sub some]) (some/do-stuff "xyz") using :refer (:require [some-package.sub :refer [do-stuff]]) (do-stuff "xyz") using alias seems more handy if dependency has plenty of functions want use or use of functions (however many there are), since clojurescript (intentionally) doesn't support :refer :all . on other hand, using :refer seems more "clean" approach, when using specific functions dependency. are there other things 1 should consider when choosing between 2 (and valid reason in first place)? another thing think of if have lots of dependencies and/or loads of own functions defined in file, might beneficial have alias prefixes in function calls make clearer functions located, if use small subset of functions offered dependency. how should choose 1 use? or should decide ...

i'm doing exponential shadow maps instead of outputing depth, output exp(depth), this: float ps_main(float4 position : sv_position) : sv_depth { return exp(position.z / position.w); } using exp() turns entire depth texture white (1.0f). i thinking no depth gets written because depth texture cleared 1.0f, max, , exp() values equal or higher. how can around this? want write float value depth texture. the sv_depth range determined depth min/max in viewport, , has maximum range of 0.0 1.0 (it unorm surface interpretation). invocations depth values outside range or greater current value of depth buffer discarded. if want encode expression in code, can either calculate on load whenever end using it, or write separate render target (e.g. r32_float ) rather using depth buffer.

i have strings, hexadecimal, "ff", "bb", "aa" etc. did small experiment encoding stuff, , looks hexadecimal taking double number of bytes these things in string representation. my code's this: string hex ="ff"; byte[] b = hex.getbytes(); string enc = base16().encode(hex.getbytes()); byte[] c = enc.getbytes(); i'm using guava utils encoding stuff. it appears hex taking 2 bytes, b of length 2. encode hexadecimal.

i have implement matrix class using 2 dimensional vectors in c++ ( vector<vector<float>>() ). want optimize code using gpgpu using opencl. runing in problems every miniute. please me , give me tips this. my requirements follows since want use matrix library implement machine learning algo there may huge matrix, 1000*400. can use 2 dimensional vectors , transfer them opencl kernels (because if can use vectors implement class more easy implementing these scratch using array). one of code segments follows, here in kernal try add 10 every element. but output shows change values in frist vector[0][n] elemets. this segment in host program.... int in_vec_size = 100; int out_vec_size = 100; vector<vector<float>> in_vec(10,vector<float>(10)); vector<vector<float>> out_vec(10, vector<float>(10)); int k = 0; //initialize input vec (int i=0; < 10;i++) { (int j = 0; j < 10;j++) { in_vec[i][j] = k++; ...

i've been reading lot event loop, , understand abstraction provided whereby can make i/o request (lets use fs.readfile(foo.txt)) , pass in callback executed once particular event indicating completion of file reading fired. however, not understand function doing work of reading file being executed. javascript single-threaded, there 2 things happening @ once: execution of node.js file , of program/function reading data harddrive. second function take place in relation node? "of course, on backend, there threads , processes db access , process execution. however, these not explicitly exposed code, can’t worry them other knowing i/o interactions e.g. database, or other processes asynchronous perspective of each request since results threads returned via event loop code. compared apache model, there lot less threads , thread overhead, since threads aren’t needed each connection; when absolutely positively must have else running in parallel , management handled node.j...

how can th of td in datatables? right have code can use add attribute td's on datatable: "fnrowcallback": function( nrow, adata, idisplayindex, idisplayindexfull) { $('td', nrow).attr("title","pummm"); //takes tds row , assigned title attribute } what want put different attribute depending on header particular td have. do mean this? sorry, dont know plugin... var columnumber = 0; "fnrowcallback": function( nrow, adata, idisplayindex, idisplayindexfull) { $('td, th', nrow).each(function(){ var $this = $(this); if($this[0].tagname == "td"){ switch(columnnumber) { case 0: $this.attr("title","column 0"); break; case 1: $this.attr("title","column 1"); break; ...

essentially, have multidimensional array (it's more extensive bare skeleton need access): $arr = [ 1 => [ 'val1' => 'foo', 'val2' => 'bar', ], 2 => [ 'type1' => [ 'val3' => 'baz', 'val4' => 'fuz', ], ], ] i accessing array dynamically , won't know whether i'll accessing $arr[1] or $arr[2] until try so. therefore, don't know how many levels deep need go until time comes. looking function accesses varying number of levels deep of multidimensional array can't find that. know can if or switch statement i'm trying simplify like: if ( isset( $arr[$var]...... ) ) { return $arr[$var]......; } my problem can't figure out how build string replace "......" proper number of indices. tried making string using loop: function getaccessstring( array $arrofindices ) { $str = ...

there 2 sets of data in 2 lists. lists x=[1,2,3,...,1000] , y=[0.12,0.59,-0.89,...,0.45] . i want plot them in xy coordinate. searched on net , figured out should download matplotlib , anaconda did. due fact new python user, not figure out how plot it. here's simple example: import matplotlib.pyplot plt x =[1,2,3,10] y =[0.12,0.59,-0.89,0.45] plt.plot(x, y, 'o-') plt.show()

chrome, firefox , safari supports tranformation of svg <g> element css style without prefixes, while internet explorer , android 4.2.0 browser not support it. i want check if browser supports feature or not javascript, example this: if ( svg_css_transform_supported() ){ //do something; }else{ //do nothing; } this jsfiddle tutorial running on supported browsers: http://jsfiddle.net/samehobada/w95298kf/ function svg_css_transform_supported() { var svg = document.createelementns("http://www.w3.org/2000/svg", "svg"); return 'transform' in svg; }

i'm building out site using fullpage.js, has overlay pops , covers entire page. inside overlay, div setup overflow: scroll, can see of content. problem lies in when scroll thru content of overlay, scrolling of fullpage.js still going on background slides, causing end on random slide when close overlay. is there way disable scroll functionality slides, without effecting scrolling of div set overflow:scroll? using option normalscrollelements fullpage.js plugin provides: from the documentation : normalscrollelements: (default null) if want avoid auto scroll when scrolling on elements, option need use. (useful maps, scrolling divs etc.) requires string jquery selectors elements. (for example: normalscrollelements: '#element1, .element2')

i following spring-data-rest guide accessing jpa data rest . when http post new record inserted (and response 201). great, there way configure rest mvc code return newly created object? i'd rather not have send search request find new instance. you don't have search created entity. http spec suggests, post requests returning status code of 201 created supposed contain location header contains uri of resource created. thus need issuing get request particular uri. spring data rest has 2 methods on repositoryrestconfiguration.setreturnbodyoncreate(…) , ….setreturnbodyonupdate(…) can use configure framework return representation of resource created.

i have numpy array n rows of size 3. each row composed 3 integers, each 1 integer refers position inside numpy array. example if want rows refered n[4] , use n[n[4]] . visually: n = np.array([[2, 3, 6], [12, 6, 9], [3, 10, 7], [8, 5, 6], [3, 1, 0] ... ]) n[4] = [3, 1 ,0] n[n[4]] = [[8, 5, 6] [12, 6, 9] [2, 3, 6]] i building function modifies n, , need modify n[n[x]] specified x parameter (4 in example). want change 6 in subarray number (let's 0), use numpy.where find indexes, are where_is_6 = np.where(n[n[4]] == 6) now, if replace directly n[n[4]][where_is_6] = 0 there no change. if make previous reference var = n[n[4]] , var[where_is_6] change done locally function , n not changed globally. can in case? or doing wrong? sounds need convert indices original n 's coordinates: row_idxs = n[4] r,c = np.where(n[row_idxs] == 6) n[row_idxs[r],c] = 0

i writing scala backend uses eclipselink data abstraction layer. i find having problems right out of box, although several tutorials have followed indicated no such thing. example, 1 of entities this: @mappedsuperclass abstract class entity { @id @generatedvalue(strategy = generationtype.auto) @expose @beanproperty protected var id: int = 0 } @entity class user extends entity { @expose @temporal(temporaltype.timestamp) @beanproperty var createdat: date @expose @temporal(temporaltype.timestamp) @beanproperty var updatedat: date @expose @temporal(temporaltype.timestamp) @beanproperty var dateofbirth: date @expose @beanproperty var twostepverificationcode: string @expose @beanproperty var firstname: string @expose @beanproperty var lastname: string @expose @beanproperty var email: string @expose @beanproperty var description: string @expose @beanproperty var password: string @expose @beanproperty...
