  1. 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...
  2. Extending Tag Helpers in ASP.NET Core

    A few days ago, I was answering questions on Stack Overflow when I came across one that I thought might be relevant to share with others that might have a similar issue. The issue itself revolved around Tag Helpers, and in particular, getting data attributes found on models to properly generate the appropriate attributes when rendered.This post will introduce how to easily extend an existing tag helper for a common use-case. It will primarily focus around the use of the Input Tag Helper, the [MaxLength]...
  3. The Path is Null and Full of Squiggles

    I've been using Visual Studio 2017 since the earliest bits were available and I can confidently say, I'm a fan and highly recommend you give it a shot if you get a chance.With that being said, sometimes new features can cause things to blow up and this post is going to be discussing one of those such features, namely Lightweight Solution Load.Recently, I opened up a decently sized solution (~9 projects) and everything seemed in order. All of my dependencies were there, with no warning signs to be...
  4. Glyphfriend 2.1 Released! Now with Library Filtering

    It hasn't been too long since the latest 2.0 release of Glyphfriend, but with the release of Visual Studio 2017 coming around the corner, there were a few things that could use some improvement and polishing off before then.Message received, loud and clear.All of the changes that were made to make the extension more flexible actually resulted in it being more noisy. Glyphfriend would just serve everything it knew about. This has generally been regarded as a bad move, and thus library filtering is...
  5. 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...
  6. Setup Eclipse CDT with cygwin

    Eclipse CDT is one of the powerful C++ IDEs in the world. However, it's not easy to configure it for a fresh new user. I found rare article to show the detail steps for setting up CDT with cygwin on the internet. So I decide to write down this tutorial for newbies.Purpose: This article intends to summary the steps to configure Eclipse CDT for the general C++ development.1. Project -> Properties -> C/C++ General -> Preprocessor Include, select CDT GCC Built-in Compiler Settings Cygwin, check...
  7. 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.
  8. 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...
  9. 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...
  10. Configure RoundCube on Debian 8 (Jessie) - Perfect Server Debian 8 (Apache, BIND, Dovecot, ISPConfig 3)

    Debian 8 (Jessie) doesn't contain RoundCube in it's repositories. Why, I don't know :) . In ISPConfig3, Perfect Server, Debian 8, you get SquirrelMail, but I don't like how it looks. With some trouble setting it up, I managed to configure RoundCube on Debian 8 and make it wokring with ISPConfig3. Used many sources to make it work and decided to create this manual that you’re reading.I presume that you have configured your server with Perfect Server Debian 8 (Apache, BIND, Dovecot, ISPConfig 3) configuraton...
