  1. Introduction to Progressive Web Apps

    As some people know, I have been very passionate about Windows Phone since the early days of the platform. I am still using a Windows 10 Mobile device, and I still love the operating system and the Windows 10 platform. However, I am not living in a cave, and I do realise that the future potential of the Windows mobile platform is limited. I still don't think it is "dead", but it is certainly limited. I started learning Xamarin a couple of years ago, to use my C# knowledge and skills for building...
  2. Lessons Learned Writing Spring Boot Auto Configurations

    My team and I make heavy use of Spring Boot to build microservices that power our applications at our company. We've even gone so far as to write our own custom auto configurations to ease development. We package these auto configurations along with other goodies into what we call our platform.Recently, after releasing a new platform version, we encountered an issue where one of our microservices would fail to start at what appeared to be random intervals. After further digging, we noticed specifically...
  3. Spring Cloud and Netflix Ribbon: Client-side Load Balancing

    Eventually you'll reach a point where you need to run multiple instances of an application or a service for high availability or to manage increased load. That's what load balancers are for. There's generally two different types:What many people would call a "load balancer" is actually a server-side load balancer. It can be implemented in hardware or software. The traffic is sent to a dedicated service that decides where to send the traffic, using an algorithm like round-robin, to one of the...
  4. 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...
  5. 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...
  6. An Introduction to R for Java Developers

    As a Software Engineer I'm always keeping up to date with technology and one of the things that helps me do that is book reviews. Right now, I'm reviewing The Book of R: A First Course in Programming and Statistics by Tilman M. Davies. R is a programming language used in statistical computing and has gained in popularity in the recent years due to the explosion of data and its applications like Machine Learning.
  7. The Power of PowerShell.. And the Shell..

    "What is the one technology I need to learn to get a job like the one you have?" - this is a question I've received from time to time, and my answer would vary, depending on who asked. Or rather; who I perceive the questioner to be - I cannot *know* for a fact what most suits his or her particular ambitions and style.. But in the last few years my answer, more often than not, has been "PowerShell"! Simply because I see it as one of the most important and game-changing technologies to come out of...
  8. Spring Boot 1.4: @MockBean and @SpyBean

    It's August 2016 and the Spring Boot team recently released Spring Boot 1.4 ( on July 28th, 2016 ). Some of the biggest improvements and simplifications are around unit and integration testing. We'll take a focused look at two of the newly added features: @MockBean and @SpyBeanThe newly introduced annotation, (@MockBean), adds generalized support for mocking of any Spring bean. If you've used Mockito Annotations before, @MockBean is simliar to @Mock but with Spring support.Suppose we have a simple...
  9. Trying to demystify PowerShell conditional statements processing performance

    Recently, I was drafting some PowerShell codes and stumbled across which conditional statement should I use for a very simple task and decided to explore abit more on their performance differences.Below is a sample code that I have coded to display the result of the overall performance between some of the conditional statements method and it is purely for educational coding purposes.If anyone is interested to find out, copy the codes below, paste it on PowerShell ISE and run it.
  10. 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(); ...
