Failure suuuuucks

work suggest edit

When you fail, many people will tell you how failure is a great teacher. And they’re not wrong. But you know what else is a great teacher? Success! And success is a lot less expensive than failure.

Calling internal ctors in your unit tests

csharp tdd suggest edit

One of my pet peeves is when I’m using a .NET client library that uses internal constructors for its return type. For example, let’s take a look at the Azure.AI.OpenAI nuget package. Now, I don’t mean to single out this package, as this is a common practice. It just happens to be the one I’m using at the moment. It’s an otherwise lovely package. I’m sure the authors are lovely people.

How to Recover from a DbUpdateException With EF Core

There are cases where recovery from an Entity Framework Core (EF Core) DbUpdateException is possible if you play your cards right. Play them wrong and the result is heartbreak and tears as every call to SaveChangesAsync rethrows the same exception.

Pitfalls with eager loading of collections in EF Core

When using an ORM with a web app, lazy loading will almost certainly result in hidden N+1 queries. Eager loading is a great way to avoid this, but has its own pitfalls. In particular, for each query, you need to be careful about what you include in the query. If you include too much, you can end up with a lot of data that you don’t need. If you include too little, you can end up with confusing logic. For example, deep in your application code, it may not be clear if a navigation collection has been loaded yet or not. This can lead to unexpected behavior.

Async Disposables The Easy Way

abbot csharp suggest edit

In the System.Reactive.Disposables namespace (part of Reactive Extensions), there’s a small and useful Disposable class. It has a Create method that takes in an Action and returns an IDisposable instance. When that instance is disposed, the action is called. It’s a nice way of creating an ad-hoc IDisposable. I use them often for creating a scope in code where something should happen at the end of the scope. Here’s an exceedingly trivial example:

Argument parsing with Abbot

Most Bot skills strive for a more natural language feel to arguments passed them. For example, to remember something with Abbot you can use @abbot rem haacked's blog is https://haacked.com. And then later recall it with @abbot rem haacked's blog. Or just @abbot rem haacked because Abbot uses fuzzy matching.

Introducing Abbot, a powerful ChatOps tool for collaborative work

Collaborative work is difficult enough when located together in an office. It can present new challenges when working remotely. When I worked at GitHub, one powerful tool we used that left a lasting impact on me was ChatOps. In fact, GitHub may have created the concept. If not, they were certainly one of the first.

Naming NuGet, A Lesson In Distributed Decision Making

remote nuget suggest edit

It is notoriously difficult to make decisions in a distributed asynchronous manner. It’s hard enough for me to make decisions by myself. Now introduce more people and timezones and you have yourself a hot mess. People tend to meet an online proposal with the silence of indifference. Or the silence that’s a result of the bystander effect as everyone waits for someone else to chime in.
