  1. How to read and parse a CSV file using Node.JS

    I was recently asked by someone to give an example of how to read a csv file in their node.js application, and how to parse it to get it to be usable in their app. In fact what they wanted to do is very simple, and it is one of the many reasons I'm a big fan of Node.js, because not only can it do things like this in a few lines of JavaScript, it does it server side, and fast. So This article lays out step by step how to have node.js read and parse a CSV file stored in it's project, by using the CSV...
  2. Karma Test Results with TFS Build

    Our team has been using JasmineJs for unit testing our client side JavaScript code. We now have over 3,000 tests! In order to run these tests on multiple browsers we use Karma, the "Spectacular Test Runner for JavaScript" created by people from Google to run all our tests on multiple browsers. We are also using Microsoft's TFS Build (which is leaps and bounds improved over the old XAML build system) to run our tests in Gated Check ins, create build artifacts (dlls, installers, Azure...
  3. ASP .NET MVC - SignalR and Android

    I implemented a real time web channel within an ASP .NET MVC web Application through a SignalR Hub proxy, but on most of Android Browsers it not work well. It seems to work on some recent Android Chrome browsers, anyway to have a full compatibility in the Hub initialization i had to put a fallback to the "longPolling" mode in the case of Android devices, some code like this:if (isAndroid) { $.connection.hub.start({ transport: ['longPolling'] }).done(function () { receiver.server.processEvents(); ...

  6. Ember.js and The 8 Most Common Developer Mistakes

    Ember.js is a comprehensive framework for building complex client-side applications. One of its tenets is “convention over configuration,” and the conviction that there is a very large part of development common to most web applications, and thus a single best way to solve most of these everyday challenges. However, finding the right abstraction, and covering all the cases, takes time and input from the whole community. As the reasoning goes, it is better to take the time to get the solution for...
  7. Is Math Broken in JavaScript? (Part 2)

    In my previous article we talked about how we might represent a number in memory and that the obvious way probably is not the most efficent. We then discussed another way - allow me to introduce IEEE-754..IEEE-754 is an incredibly important standard in software development & electronics and its used in a large number of programming languages such as JavaScript, C# and Java. Amongst other things it defines how numbers should be held, how they work together and how to handle errors.Well the simple...
  8. Is Math Broken in JavaScript? (Part 1)
