  1. CI/CD Pipelines: Importing and Exporting TeamCity projects across different versions

    If you develop applications and are involved with build management and pipelines then you will have heard about TeamCity, a CI / CD solution from JetBrains.Working with my current client we encountered an issue whereby we couldn't import an exported project because I was getting the below error:The selected backup file version (829) does not match the current version of the TeamCity database (856). Only backup files created with a TeamCity server of the same version as the current server are supported.
  2. New Technology - Should You Learn It?

    It is one of those questions you constantly struggle with throughout any technical career: Should I learn this latest and greatest technology that is out? Do I need to learn it, do I want to learn it, do I get left behind if I don't? The truth is that you can't learn everything so how do you know what to focus on?The sections below are not mutually exclusive, nor do you have to fulfill all of them. If you can say "yes" to one of them, then you are probably okay to invest time in the technology in...

  4. Database migrations with Continuous Delivery in Entity Framework

    Who doesn't enjoy the big term, DevOps? It sounds promising and sounds interesting as well when someone says, they work as a DevOps engineer! But like they say, Similarly, in the case of DevOps, every process, which DevOps exposes has to be handled with a great care or the results are catastrophic. In this post, I am going to talk about the swissknife of continuous delivery, in the terms of database migrations and maintenance. It has been quite a while, since I have joined DevOps practices and...
  5. 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...
  6. 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...
  7. 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...
  8. DevOps, NoOps and No Future

    In the wake of the recent MongoDB happy hour debacle, there have been a few mentions of DevOps and NoOps. The pieces were mostly about the fact that this incident proved that the IT business is not really in full DevOps mode, not to mention NoOps. I am not confident that NoOps will be the future for a vast majority of shops. Being from the Ops side of things, I am obviously biased toward anyone stating that NoOps is the future. Because that would mean no job left for me and my comrades in arms....
  9. Continuous Deployment from GitHub to Azure

    Continuous Deployment from GitHub, the web based Git source repository service to Azure, the cloud offering from Microsoft, resolves many bottlenecks related to manual application deployment. Most of the open source developers use GitHub as a public or private repository to track code changes and as a collaboration tool. Integrating or deploying applications directly from GitHub to Azure reduce the time taken for manual deployment of applications. Let us quickly see how we can deploy a small...
  10. 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.
