Let’s be honest. Our planet is churning out supercodemonsters at an alarming rate. These pinnacles of virtuosity are idols to the false gods of development ego. The pattern has always been there, but in the past it was misdirected enthusiasm. On day one you’d learn how to extend prototypes in JavaScript. On day two, everything […]
Having signed up the wait list for Hey, I received my invite and subsequently undertook a two-week trial. What happened next has changed how I interact with email forever. Although I may be repeating information that is already out there, I’m going to focus on a small number of features that let you change your […]
This month (June 2020), Depaul UK launched the #SleepBedless campaign. They asked members of the public to sleep without beds for a night to raise awareness of hidden homelessness and to help fundraise to help them with their coronavirus crisis costs. More than half of young people in hidden homelessness have suffered harm and Depaul […]
As some countries around the world lift restrictions following COVID-19 lockdowns, we can start to see the effects the lockdown will have on different companies and industries. From the data I have seen so far, the lockdown effect seems to divide organisations into three broad categories: winners, losers, and recoverees. Let’s look at what this […]
Just a quick note on a neat feature in C# 9 that will allow sub-classes to return a covariant return type… what?! Okay, it allows you to return a more specific, or narrower type. For example, we used to have to return the same type… // parent class… public virtual Literature GetLiterature(…) { return new […]
It seems like everyone has a high-quality, expensive, programmable deck on their desk these days. Elgato’s Stream Deck, with it’s glowing LCD buttons, comes in flavours that cost between £100 and £200 (depending on how many buttons you want). It’s beautiful bit of kit that glows its way into the hearts of tech geeks everywhere. […]
This neat C# 9 feature can be summed up in a tiny snippet of code. You know that code analysis warning that tells you that the argument passed might be null… wouldn’t it be nice if you could refuse to accept null? Well, you can. This is the before… public Book(string firstName, string lastName) And […]
We have taken a quick look at C# 9 Initializers and Immutability and C# 9 Non-Destructive Mutation. Let’s now look at the full transformation from an old class to a super character-light record type. Our original record type is very much just a class with two auto-properties. It looks different to a normal class because […]
There are some phrases in programming that feel like they belong in a superhero movie. Non-destructive mutation is just such as phrase. It refers to a concept in functional programming that means when you want to change the state of an object, you create a copy with the change – rather than changing the original. […]
There is currently a compromise in C# that means you can enable object initialization with getters and setters, or you can prevent external code mutating state by hiding the setter… but not both. C# 9 gives us both with the init keyword. Let’s look at before… public class Book { public string Author { get; […]
