What I Learned at Work this Week: map vs flatMap with Either in Java

When I write Java at work, I’m frequently working with vavr’s Either class. And when I’m working with vavr’s Either class, I’m confused 100% of the time. Now, I know what you’re thinking — “how could writing methods where the results could be two distinct types ever be problematic in…

What I Learned at Work this Week: A Tuple with One Element

This past week, I was tagged in a Slack thread about a Python syntax issue. I read the code, commented that I couldn’t see anything wrong with it, and offered to pair on it later if the problem wasn’t solved. …

Thanks to my experience with the ETL job I maintain, I’ve sort of become “the scripting person” on my team. On one hand, it’s a good thing because I’m good at it and I know what I’m doing. But on the other hand, it’s important to grow and I should…

What I Learned at Work this Week: Using protobuf in Java
