Jesus on prototyping, C# union types, and taste
10 Apr 2026 #mondaylinksHey there.
Here are 4 links I thought were worth sharing this week:
#1. After a long wait, C# union types are here (10min). Well, in the next C# version. If you’re new to union types, I wrote this guide (9min) when Microsoft announced the feature.
#2. If you’re new to a codebase, run these Git commands (5min) before reading any code. Treat it like a crime scene: gather evidence before touching anything.
#3. When AI makes code and text free, the only skills left are taste and judgment (10min). I liked the exercise of “fails because.”
#4. Did you know that Jesus taught about prototyping with an LLM? Here’s his advice (3min).
And in case you missed it, not much about coding on my blog, but I wrote about the secret to surviving 30 years in one job (and to live a happy life) (3min).
(Bzzz…Radio voice) This email was brought to you by… Street-Smart Coding, 30 lessons to help you code like a pro. From Googling to clear communication, it shares the lessons to help you stand out in the age of AI.
See you next Friday with more links.
Keep coding smartly.
