  1. 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...
  2. 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...
  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. 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.
  5. 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...

But the features do not end there....
  7. 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...
