Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Glad Emacs never will be sunset
Hadn't them already abandoned another one before?

Introducing Zed—A lightning-fast, collaborative code editor written in Rust by the creators of Atom.
Im super glad to see that this is probably the continuation of atom-xray and that the devs are still doing new projects! The move from web to full Rust is interesting, I wonder how it will perform.

Reject modernity
Even before Microsoft bought them they were focusing on a completely new editor: https://github.com/atom-archive/xray. That's since been scrapped, and from the contribution graph on atom it's pretty clear the only remaining development is from community volunteers.

Why is it so hard to see code from 5 minutes ago?
Before Microsoft bought GitHub and killed Atom, they were working on Xray[1] & Memo[2]:
> Memo is an operation-based version control system that tracks changes at the level of individual keystrokes and synchronizes branches in real time.

Text Editor Data Structures: Rethinking Undo
vundo is a simpler implementation: it reuses Emacs's tree and just implements the visualisation part.
undo-tree is a reimplementation of Emacs's tree based undo, that supports a visualization.

How to undo the undo
That said, the situations seems murky still: the version in ELPA is newer (0.7.5), but it's still outdated, the home page advertises 0.8.2 as the latest version. And it moved to a different repository location. And looking at its history, it seems to never have included the version 0.7.5: https://gitlab.com/tsc25/undo-tree/-/commit/5da2a7aee98393d26a93c499dc79fcf793f161e1

It’s easier to mentally map that the default behaviour undo/redo for Emacs (which is not unreasonable, just complex).
The source for undo-tree contains documentation which very effectively describes the way the library works with examples and comparisons with how Emacs does things by default: https://gitlab.com/tsc25/undo-tree/-/blob/master/undo-tree.e...
