i need test nodejs module, writes data output. wrote debugstream stream collect output data assert later: function debugstream () { stream.writable.call(this); this.data = ''; }; util.inherits(debugstream, stream.writable); debugstream.prototype._write = function (chunk, encoding, done) { this.data += chunk; done(); } debugstream.prototype.getdata = function () { return this.data; } i not want write code in every test file. nice move away somewhere, can't how organize it. can't place in test/ folder, because mocha think it's test. how that? under tests can create folders , node modules, treat tests subproject in folder required modules , tools, check example: https://github.com/edsadr/change-api/tree/master/test

currently code hiding panel (s) contained within itemtemplate of formview dependent on users role(s). the current solution: ((panel)formview1.findcontrol("pnlisadmin")).visible = isadmin; the problem code can't run until formview has been completed .databind(); now don't know formviews, surely there's way me hide controls such panel above in better place, , not dependent on .databind(); ( on page load )?? thanks information. i don't mixing code-behind & display pages, wrap control in server tags: <% if(isadmin){ %> <asp:panel id="pnlisadmin" runat="server"></asp:panel> <% } %>

hello im new php scenario this: i have created login/logout feature , event page, on event page, there join button next each event. i want decrease int value (expected number of people) in mysql database when user clicks join button. how go doing this? problem not know how associate each button corresponding event. the events dynamically created other users. the following javascript within tags $("button").click(function() { var id = $(this).attr('id'); var request = $.ajax({ url: "decrease.php", method: "post", data: { id : id }, }); request.done(function( msg ) { $( "#log" ).html( msg ); }); request.fail(function( jqxhr, textstatus ) { alert( "request failed: " + textstatus ); }); }); }); the following file decrease.php: define(...

i have converted json response pojo , following concept of full data binding . pojo looks this public class user { public name _name; @jsoncreator public user(@jsonproperty("_name") name _name,){ this._name=_name; } public static final class name { public string _first; public gender _gender; @jsoncreator public name(@jsonproperty("_first") string _first,@jsonproperty("_gender") gender _gender){ this._first = _first; this._gender = _gender; } public static final class gender { public string age; public gender(@jsonproperty("age") string age){ this.age=age; } } } } now need persist pojo , not sure how should efficiently, have consider using hibernate unaware how proceed. how fields annotated in case use hibernate, since complex pojo . is there way use jdbc ...

i have two, 2 dimensional lists list 1 = [[none, none], [none, none], [none, none]] list 2 = [[1, 2], [3, 4]] the desired output is list 3 = [[1, 2], [3, 4], [none, none]] in case there simpler solution, i'm doing because don't have data third element in list. need list have 3 first level items. i'm trying stop script throwing out of range error. some additional context address below questions. this comes in app when database query returns result put list, e.g. 'biggest 10 problems'. things aren't bad, , there 9 problems. when part of application looks 10th problem (a flask website), throws error. try/except indeed work, pretty heavy. so need solution can create list of placeholder values, , overwrite them data if available. the accepted solution works great 1 line of code. i think meant list_3 = [ list_2[i] if < len(list_2) else e i,e in enumerate(list_1) ] here equivalent without list comprehension list_3 = list() i,e i...

i wondering if can use fileutils.cp_r method copy files , directories source target except .tar files. can give me example better understanding? thanks sure you'd have implement kind of filter first this: [8] pry(main)> dir.glob("**/*") => ["bin", "code_of_conduct.md", "gemfile", "gemfile.lock", "hello.tar", "lib", "license.txt", "mygem.gemspec", "rakefile", "readme.md", "spec"] that gave files in directory , subsequent directories(thanks ndn tip), let's filter out hello.tar : files = dir.glob("**/*").reject { |file| file.end_with?(".tar") } now can pass array filteutils::cp_r fileutils.cp_r(files, destination)

so per documentation https://developer.github.com/v3/repos/releases/#list-releases-for-a-repository get /repos/:owner/:repo/releases should list relases , https://api.github.com/repos/jquery/jquery/releases should list releases in jquery project , not , why ? because repository doesn't have releases. has tags github presenting in releases page. for more clear example, see: https://github.com/hashicorp/terraform/releases which has both releases , tags showing on page, api shows releases: https://api.github.com/repos/hashicorp/terraform/releases

i'm trying make program use readings gets distance sensor control attributes of circles (size, xy , colour). i'm trying make record current value , apply value when press relevant key (eg. press 's' , changes size whatever distance @ point). - ideally i'd circle change whatever field next dynamically move hand on sensor, seems bit beyond me. i've tried as can, i'm not sure of i've commented out. tips or advice? i'm not sure i'm doing when comes classes , constructors. edit: when run code, nothing happens. import processing.serial.*; int xpos, ypos, s, r, g, b; circle circle; int shapesize, distance; string comportstring; serial myport; void setup(){ size(displaywidth,displayheight); //use entire screen size. //open serial port communication arduino myport = new serial(this, "/dev/cu.usbmodem1411", 9600); myport.bufferuntil('\n'); // trigger serialevent on new line } void draw(){ background(0); delay(50); //del...

i'm using emu8086 on windows 7 hp x64, intel i3-2330m pc. i have spent 2 weeks researching , tinkering assembly language program in effort print hex value of integer entered user. have found nothing directly printing value memory location. can, if necessary, write code string conversion hex. however, attempting avoid lines of code this. (i think called optimizing.) my research has lead me comment on site corbin says: very unpleasantly. you'll have determine value of decimal string ("100"), make new string same value in hex ("0x64"). it's same algorithm use conversion in head; it's bit more complicated since have deal ascii encoding on top of things. none of has directed me manner in desire perform task. i have written , tested code incrementally, receiving desired results. watching variable , viewing cx register, can confirm values values want print. i including code here. ugly , over-commented. commenting benefit me lear...
