I have spent 2 days postponing very weird bug with @types/aws-lambda in my serverless project. Finally I decided to fight the fight and try to understand what's going on.

In my previous company I've been irregularly curating [^1] the list of articles I came across in my spare time. I was distributing it as "newsletter" [^2] - I wanted to inform my colleagues about various cool new technologies and about how things are done elsewhere.

I no longer have colleagues but I still have lot of articles which I want to post somewhere. This could've been 7th issue.

When I was trying Bun S3 client for the first time I was surprised that there is no option to pass AWS profile name as credentials. This post is just a quick memo for me to remember how this can be achieved.

Have you ever wondered who might have thought of TypeScript enums? I did because of all the ways how that can go wrong but I actually never found out who has introduced this feature to the language. This article is not about that either.

I tested Valibot as viable alternative to yup approximatelly 3 years ago. Today I use it everywhere.

I just wanted to build simple static site so I can publish something from time to time - I had no idea that it was not that easy in 2025.
