Project mention: Ask HN: What is new in Algorithms / Data Structures these days? | news.ycombinator.com | 2023-05-10How about some succinct data structures and delta encoding for modern databases [1]. Succinct data structures are a family of data structures which are close in size to the information theoretic minimum representation (while still being queryable).

I've been working on an editor (not text) in C++ and pretty early got into undo/redo. I went down the route of doIt/undoIt for commands but that quickly got old. There was both the extra work needed to implement undo separately for every operation, but also the nagging feeling that the undo operation for some operation wasn't implemented correctly.
In the end, I switched to representing the entire document state using persistent data structures (using the immer library). This vastly simplified things and implementing undo/redo becomes absolutely trivial when using persistent data structures. It's probably not something that is suitable for all domains, but worth checking out.

Project mention: Is there a way to atomically add to a list and return its index? | /r/Kotlin | 2023-12-08In Clojure, it is called an Atom. I created my own via AtomicReference and https://github.com/Kotlin/kotlinx.collections.immutable. It works really well in Kotlin. It works especially well if you use tons of coroutines.
I've been eyeing Kairos [1] which is an OS lifecycle management system for k3s which looks like a nice way to deploy k3s.

Project mention: Bare minimum atw-style K interpreter for learning purposes | news.ycombinator.com | 2024-01-17I recommend checking BQN at https://mlochbaum.github.io/BQN/ and the YouTube channel code_report by Conor Hoekstra (and also "Composition Intuition by Conor Hoekstra | Lambda Days 2023"). It is well documented.
That flagship app you are looking for seems to be https://nft.storage/ (by Protocol Labs).

See the author instantly opening a ~1GB text file with async loading, paging through, copying/pasting, and undoing/redoing in their prototype “ewig” text editor about 27 minutes into their talk here:

It’s backed by a “vector of vectors” data structure called a relaxed radix balanced tree:
