Endjin - Home

Howard van Rooijen's Blog

When we setup endjin in 2010, there were five activities we did on day one: set up a business bank account, set up a FreeAgent account, for all our accounting needs signed up for Office 365 (or BPOS as it was then), registered the endjin GitHub account built a virtualised Continuous Integration Environment using TeamCity.

Agile:MK January 2013 Meeting

by Howard van Rooijen

Technologists who work in London are very spoilt for choice when it comes to user groups – there are generally more on in any month that any single person can attend. Unfortunately if you live or work outside of London – depending on the area – it can be a bit desolate. Endjin are proud […]


Calculating Distance using SQL Server Spatial CLR Types

by Howard van Rooijen

I created a quick sample to solve a problem today and thought I’d post the code as it took me a while to track down all the relevant bits of information. The problem I wanted to solve was that I needed to be able to geocode a user’s postcode and then calculate the distance between their […]


TeamCity PowerShell

by Howard van Rooijen

Last week I was formally invited to become a member of the JetBrains Development Academy Board – to celebrate, I decided to give something back to the community that has a JetBrains flavour. As I mentioned in my last post – we’ve been doing a lot of ALM / DevOps work in the last year […]


An Omega Geek’s Guide to Learning PowerShell

by Howard van Rooijen

In the last 12 months we’ve been doing quite a lot of Application Lifecycle Management (ALM) projects helping teams setup Continuous Delivery processes. One of the tenets of Continuous Delivery is “Automate Everything” – which has been a core part of my “work smarter, not harder” ethic for a number of years. The technology that […]


Dev4Good July 2011

by Howard van Rooijen

Ethical Foundations When we founded endjin, Matthew, Lloyd and I spent a lot of time thinking about the type of company we wanted to create; one recurring theme was that in our personal time we each did a significant amount of work for “good causes” and we derived a huge amount of joy and satisfaction […]


A few weeks ago Geoffrey Smith, the Sharp Architecture Development Lead and I were invited onto .NET Rocks! to be interviewed about the Sharp Architecture project. After we talked about Sharp Architecture – the conversation lead on to other open source projects I’ve been involved with such as Templify and StyleCop for ReSharper. You can listen to the […]


StyleCop and StyleCop for ReSharper have merged

by Howard van Rooijen

In 2008 Microsoft released Source Analysis a tool to help solve the thorny problem of coding standards in C# projects, soon afterwards they re-launched it using it’s original internal Microsoft name, StyleCop (to avoid confusion with the TFS Code Analysis tools), along with an SDK that allowed the community to extend the product. In May […]


On Apprenticeships…

by Howard van Rooijen

I’ve always been surprised by the number of people within the technology sector, in particular the software development industry who don’t have a  traditional computer science background. Some of the most talented software developers I’ve worked with have university backgrounds in chemistry, astrophysics,  geography, marine biology, just not Computer Science, and two of the most […]


Large productivity gains can be made by adopting a “Convention over Configuration” (CoC) approach when designing new solution architectures. To harness the full power of the Convention over Configuration approach, the development team must take a holistic approach by examining the ceremony required at every stage within the Software Development Life Cycle. In a previous […]


A Step by Step Guide to MongoDB for .NET Developers

by Howard van Rooijen

I originally published this post on my personal blog but decided to revisit it and update it with a few things I’ve learnt in the following months. During DDD8 I attended Neil Robbins “Hello Document Database” talk, where he demo’d how to get started with CouchDB. Although I have heard a lot about the NoSQL […]

Because we believe in working smarter, not harder, our Issue and Bug Tracker of choice is JetBrain’s YouTrack. This is our second Step by Step Guide, which follows on from […]

The inimitable Ian Griffiths left a great comment on my last post – saying that: You seem to be implying that the LINQ query was being evaluated each time round in “the outer foreach”. But I don’t think that’s right. A foreach loop evaluates its collection expression just once at the start of the loop. […]


A Short Tale of a Deceptively Slow LINQ Expression

by Howard van Rooijen

With any good iterative development process – the first step is to get something working: solve the problem in as simple a fashion as possible, then refactor. Part of the refactoring consideration should be an initial performance monitoring spike to see which parts of your codebase are running slow. Once I had the initial prototype […]


Introducing Templify

by Howard van Rooijen

[Note: Templify 0.7.0.25 is now available] In my last post I talked about the philosophy of “Work Smarter, Not Harder”; it’s a very simple mantra that can be described in three simple steps: Do, Recognise, Codify. This philosophy is at the very core of what we do at endjin so we decided to share the […]


Work Smarter, Not Harder

by Howard van Rooijen

The simplest definition of my mantra of  “work smarter, not harder” is: Using your intellect, skills, established patterns, tools and a fundamental understanding of the problem space to create an elegant solution, instead of a purely brute force approach. So many people jump straight into trying to solve a problem without actually trying to understand […]
