#programming #CSharp

In recent years, there’s been a trend of strict null checking in programming languages:

* TypeScript has the strictNullChecks option.
* In Kotlin (preferred language for Android development), all types don’t allow null values by default.
* In Swift (Apple’s language of choice), only the Optional data type allows null values.
* Nullable reference types bring similar functionality to C#. The feature was originally planned for C# 7 and was finally released as part of C# 8.

In this tutorial, author looks at the state of the Nullable Reference Types feature in C#, one year after its initial release:

⭐️ “How to automate your #swagger” by Bogdan Lobor

Let's talk about how we can automate things, moreover how we can build API-first services.

This article says it's about #SLOs, but it's really about measuring #latency. Gil Tene (CTO of Azul, the high performance JVM company), has a bunch of talks about this, which he calls “coordinated omission.” If you search for Gil and that term, you'll find lots of talks and posts about it.
