Re:S3 is not a filesystem, and LSM trees never needed one [video]

Author here. This is episode 3 of a series on LSM trees, from first principles to production systems.
I started this cause I like object storage, databases and I was really into SlateDB.
Now with manim and Claude, we can do good videos, so I started this series to share the inner guts to others.
Every claim has a source in the description. A fact-check pass corrected a few things along the way. If you spot anything else wrong, please tell me to update the description.

Re:Mojo.js is a port of Perl's Mojolicious to TypeScript

I was really excited with the first benchmarks but I ended writing a new APIs using nestJs instead. maybe if mojo.js goes towards zero deps and start running in bun, we could use it on microservices where speed is really important but don't want to add another language on the stack (eg: go/rust)
I actually feel kinda sorry for the perl, I've been programming it for 10 years now (lots of projects with mojo and catalyst) and after a while getting use to not so good ORM (like dbic is) I'm no longer interested in writing any new perl for brand new code. typescript with the static type check is too good
