When I noticed performance problems on my site, my initial thought as a backend developer was:
"Maybe I need a CDN. Maybe new caching rules. Maybe infrastructure changes."

But the real fix? Just 3 lines of HTML.

🎥 If Your Integration Tests Feel Impossible to Debug, Watch This!

Ever tried debugging an integration test, only to get nothing in your output window?
No logs, no console messages, just confusion.

That's exactly what xUnit v3 fixes with CaptureOutput.

Watched a senior dev spend 3 days testing code that took 2 hours to write.
Why? He wrote it backwards.

Most C# devs do.

I did too—until I learned to write code that wants to be tested.

I packed 15 years of lessons into a 4h course.

Do you know if there is any data on the age distribution of .NET developers (like the one in the image)?

I'm trying to confirm a theory 😉

I'm writing this week's newsletter, and I noticed I've changed my belief system.

"Do it just because it's cool"

"It's just perfect for immediate use!"

That's what our students say about our OpenTelemetry in .NET course.

Why Testing?

5 minutes and 15 seconds a year is how long your cloud applications can be down, even if you go the extra mile.

Even the hard-to-get famous five nines (99.999%) feel perfect until we know what they mean.

There's no perfection.

This book is a brilliant story of authentic leadership.

This goes directly into the highlights of 2024.

"Keep Coding" is not only Nick Chapsas synonym but also part of the collective history of hashtag#dotnet.

If you recognise it, it means that at some point, you relied on Nick to keep up with .NET. We have that in common.

I'm not sure how I feel about these numbers...

2023 vs 2024 on YouTube.

I always have a yearly goal for what I want to learn.
A skill, a language, a framework, etc.

What do you plan to learn next year?
What's on your list for 2025?

YouTube is such a great place for self-esteem 🙃
