Development

We’re currently working on a project to migrate a customer from AWS to Azure. As always, we like to put a Continuous Delivery pipeline at the heart of the project to ensure there is zero friction pushing out changes across all dev, test and production environments. Two years ago I wrote about the process we […]


In February 2016, I completed my second year of endjin’s three year custom apprenticeship scheme. This blog is a chance for me to reflect on what was learnt over the year – hopefully others will find it useful too. Year one had involved a very steep learning curve as I transitioned from student to graduate […]


My Apprenticeship Retrospective

by Mike Larah

A few years back, Howard wrote his thoughts on apprenticeships, drawing from his own experiences, whilst endjin were in the process of planning their own unique apprenticeship scheme. I was fortunate enough to be selected as their first candidate (guinea pig?) and, as it is National Apprentice Week this week, I thought I would write […]


Over a year ago, I wrote a similarly titled post on how to use Azure Automation to run VMs during office hours only. Since then, much has changed with Azure Automation and the previous management portal has been replaced. This post goes through how to achieve scheduling of VM running times using the current portal […]


It’s #FinTechWeek in the UK, which means it’s the perfect time to share a customer story; for the past 3 years endjin have been helping Hymans Robertson, a market leading actuarial consultancy who have realigned their business towards innovation, placing FinTech and the cloud at the heart of their offerings in the emerging API, Data, […]


Like many other developers I’m sure, I spend quite a bit of time in command line applications (Windows CMD, PowerShell, etc.). Unfortunately, these applications don’t offer a lot in terms of customization. So I use ConEmu – a highly customizable, tabbed console emulator that lets you run any shell you want. This post describes how to setup ConEmu, and how […]


As I mentioned in a previous post (and also covered by Matthew) at the start of every year we clean up our core intellectual property (~100 projects), and re-evaluate our tool-chain. NuGet Packages are now the de facto standard (for better or worse) in the .NET ecosystem, and have become one of the biggest causes […]


SpecFlow 2.0, NUnit3, Visual Studio and TeamCity

by Matthew Adams

We have recently upgraded our build environment to use SpecFlow 2.0, and NUnit3. NUnit3 is supported by the latest build of TeamCity, and there is an NUnit3 Test Adapter for Visual Studio, but there are a few gotchas. The first is to do with the base directory set by the NUnit Test Adapter in Visual […]


ILMerge Meta-Runner for TeamCity

by Howard van Rooijen

At the start of every year we do a spot of spring cleaning; we tidy up all of our core intellectual property, harvest any useful code that we’ve written in the previous year, then give it all a thoroughly good refactoring; to ensure that the code is self-referencing all the new patterns and concepts. This has […]


What is Azure Resource Manager? The infrastructure that makes up your application is often composed of various different components. For instance, you might simply be running a web site, but behind the scenes you have an Azure web site deployed, a Storage account for tables, blobs, and queues, a couple of VMs running a database […]


Endjin.Licensing now supports SHA256

by Howard van Rooijen

Last year we open sourced an extensible licensing framework we created for an Azure / .NET based content platform we’re developing. We’ve just pushed an update that supports SHA256 for signing the license XML document. As this is a breaking change we’ve bumped the version number of the NuGet package to 2.x. For more information […]


Since .NET 4.0, the ConcurrentDictionary<TKey, TValue> collection type has been available as a way of ensuring thread-safe access to a collection of key/value pairs, using fine grained locking. The collection also has AddOrUpdate and GetOrAdd methods that accept delegate value factories, so that you can lazily load your values only when you need to initialize them. […]


Azure Batch – Time is Money in Big Compute

by James Broome

Earlier in the year, endjin worked with the Azure Batch Product Team to run a series of experiments against the Azure Batch service using a framework we developed for performing scale, soak and performance tests. We’ve had conversations with a number of organisations over the last 5 years who have scaled their compute intensive workloads (SAS, […]


Chaos with a rhythm – controlling innovation

by Matthew Adams

Running a start-up or bootstrapping a new product within an established business can feel pretty chaotic. Ideas develop, explode, or fade into silence. You are pulled in different directions by investors (present and future), customers, regulators, your team, the competition. It seems that everything needs to be done yesterday, but nothing is ever finished. Our […]


At endjin, we love using Gherkin, from “unit”-style tests, all the way through to Integration and User Acceptance testing. In the .NET world, we make use of SpecFlow which has great integration with Visual Studio. With Visual Studio 2015 and its new support for npm/grunt, setting up CucumberJS for gherkin-style testing of JavaScript is pretty […]


Previously each component in Azure was deployed, managed, billed and monitored separately. Azure Resource Manager (ARM) is a new approach that allows you to declaratively state what a group of Azure infrastructure should look like as a template, then deploy that template in an idempotent way (i.e. you can run it multiple times and it […]


The Problem If you use Git (and GitFlow) with Visual Studio (which seems like it is going to become a much more popular combination), I’m sure you are well aware of the pain that is the “merge conflict” you often encounter when trying to merge (or rebase) a branch. There are three file types that […]


SpecFlow Extensions for Azure Storage Emulator

by Howard van Rooijen

In most cases, when writing an integration specifications against Azure Storage, you want to use the real thing rather than the Storage Emulator as the performance profile and behaviours are noticeably different. One exception is if you’ve hosted your code in a public repo; in this case you really don’t want to commit your real […]


A CDN, short for Content Delivery Network, is essentially a network of servers set-up, in various geographic locations, with the aim of speeding up the delivery of content to end-users across the Internet. […]


Azure Automation scheduler and daylight saving time

by Richard Kerslake

Update 18/10/16: Azure Automation schedules do now support time zones, which means they can properly adjust for daylight savings! To use this feature creating a new schedule is required – all existing schedules prior to the release of this feature will be stored in UTC. Specifying a timezone in the portal looks like this: Daylight […]
