First impressions on #github sponsors from dry-rb creator.

> It can become a job and for many Open Source contributors it does become their second job. The problem? Nobody really has the time to do this job and to make things worse barely any Open Source contributor is being paid to do it. As a result many contributors flip the table and quit. This is the reason why I am very happy to see GitHub Sponsors!

Have you ever tried to:

- Create complex generic types in your own project?
- Write distributable stubs for your library?
- Create custom mypy plugin?
- Write custom type-checker?

In case you try to do any of these, you will soon find out that you need to test your types. Wait, what? Testing types?!

​​Right after Nominal Types #ts might also get Optional Chaining.

ORMs are something that seem cool until you have to do anything with them, and then they just get in the way. Their promises (backend-agnostic, write type-safe native code, less boilerplate) sometimes have a catch and sometimes are just false.

The reason for this is that ORMs are backwards: they force you to design schemas in your implementation language (python, javascript, java) and then export them to #sql ‘somehow’. (The ‘somehow’ is usually a half-baked migration tool). This is bad for a lot of reasons and horrible if you want to access your data from another language.

- Tiny (~600B)
