Yeah you should try it. I place a very big value on simplicity and code size but the combo you describe might have benefits.

I used this data structure in my immutable database (see profile) but eventually switched to a B-tree because I believe RRB trees are inherently flawed. If you do a large number of slices and concats, it is possible for the tree to contain

Blue badges were for government employees (like I was), and green badges were for private contractors. And yes they have a lot of math and physics guys; my own physics lecturer was in my orientation class, actually. He was there for quantum

I can't say what they're doing now because I worked for the NSA 15 years ago but the view of them as an omnipotent power is a product of Hollywood. The government is good at throwing an ungodly amount of resources at something to

Yes the article I linked mentioned d/with (speculative writes), and you are right that it is useful for testing -- but not much else, since it is purely in-memory. If you want to call that in-memory branching that's fine, I'l

If each "branch" is read only, it's not a branch at all. The entire idea of branching implies that you can make changes on one branch, then switch to another branch and make changes to it. They start from the same point and g

Surprisingly, neither Datomic nor XTDB support branching. See: https://blog.danieljanus.pl/datomic-forking-the-past/ I actually built my own immutable database which does support branching (see profile), so it seems

I really like it. API-first git repos without the limitations of a git service like github that are built primarily for humans. Looks like a competitor to code.storage by pierre. Zig is a great choice. I spent the last three years working o

What a banger of a release. The new `Io` interface was a huge breaking change for my project, but I made the transition. Zig seems to be pulling the same trick it pulled with allocators: just make it an explicit value that you pass around.

Clojure's immutable HAMTs are still a superpower nearly 20 years later. They've been copied in pretty much every language as a library (I did so myself in Zig) but what really makes it work well in Clojure is the fact that they&#x

True, git poorly imitated monotone's performance problems.

I think astronomers could measure the age of the universe in nano-Valhallas. Every year, it feels 50% closer to completion... In all seriousness I'm happy with what Mr. Goetz and the team have done. Sealed interfaces (java 17) + exhaus
