Development

This has been sitting in my “blogs” folder for some time, with little more in it than a first sentence about the fact that I haven’t written this blog yet. Whilst going over C#, reactive extensions have been one of the things that I have struggled to get my head around the most. I think […]


Overflowing with dataflow part 2: TPL Dataflow

by Carmel Eve

Edit: In case you missed it! Here’s a link to part 1, a general overview of dataflow as a processing technique! The specific implementation of dataflow that I want to talk about is the TPL dataflow library. The task parallel library is a .NET library which aims to make parallel processing and concurrency simpler to […]


Overflowing with dataflow part 1: An overview

by Carmel Eve

In a recent project, I was asked to produce a tool for importing a fairly large amount of data at once, this data then needed to be processed and exported. After much refactoring, I achieved a solution I was satisfied with which used TPL dataflow to execute the processing in parallel. Before I talk specifically […]


When I am learning something new and it’s programming related I normally find the best way to learn is to write my own implementation. I have been reading a lot about dependency injection so I thought it would be worthwhile to create my own DI framework so I could see how it actually works. I […]


Async pitfalls: deferred work and resource ownership

by Ian Griffiths

Asynchronous code has many traps for the unwary. In fact, it has plenty of ground that’s treacherous even for pathologically careful coders. For example, certain ways of using asynchrony can reduce the control you have over concurrency and ordering. This can result in subtle bugs, particularly when the asynchronous work operates on shared underlying resources. […]


(TL;DR This month I learnt a lot about the importance of package management, maintenance and the minimisation of dependencies.) It’s been a little while since my last blog, I’ve been pretty bogged down in a world of packages, .NET frameworks and testing. And it all started with what I thought would be a simple update […]


I’m very excited that Ian Griffiths has joined endjin as a “Technical Fellow”. This is a new career pathway branch we created especially for Ian, as he didn’t really fit into any of our existing roles; his skills and expertise exemplify a pathway that many software engineers desire, but few have the opportunity to achieve […]


Disclaimer: This is not an in-depth overview of encryption and data management, more a slice of the concepts I’ve come across as a relative newcomer to this world (i.e. I’m new, please forgive my relative ignorance). A brief introduction to hashing In order to talk about cryptography, we first need to understand hashing. In a […]


Not coming from a background in computer science, the inner workings of a computer have always been somewhat of a mystery to me. This is something I’ve always meant to remedy but never quite gotten around to. When I transitioned from C++ to C# my main thought surrounding memory management was “well thank god I […]


I’m back! Hi everyone. It’s been a long while since my last blog. *Bows head in shame* Blogging is one of those things I know I should do more often, but I’m still not in the routine in which one needs to be in order to do it regularly. As a consequence, what usually happens […]
