Vundo is great! (visual undo-tree for emacs-28)
Try undo-fu, it's a thin wrapper on emacs built-in undo/redo but doesn't have this limitation.
-
undo-hl: highlight to-be-deleted text before undo operation happens
Try undo-fu it was written to address exactly this problem.

Org Mode: Are you ever concerned that you might make some major editing mistake and lose some data?
Emacs has a good built-in undo function. And that one can be beefed up further with undo-tree --- which I used for some years --- or undo-fo --- which I use now ---.

The 6 Emacs Settings Every User Should Consider
I switched back from undo-tree to undo-fu, which re-uses the emacs undo-system instead of replacing it and makes it more intuitive to use while still preserving the full undo history. I sometimes miss the nice visualizations such as the tree and I didn't even know (or remember) the diff, but in 99% of cases I just need simple undo and most of the time I have git anyway to save intermediate states of my files.

Emacs noob here. How do I get redo functionality in evil mode? When I hit C-r, I see "customize 'evil-undo-system' for redo functionality", but I have no Idea what that means or how to do it. I assume there's some line I should add in my .emacs file?
There are packages that were written to add an explicit redo command, such as Undo Fu (https://gitlab.com/ideasman42/emacs-undo-fu) and Undo Tree (https://www.dr-qubit.org/undo-tree.html). Again, these packages are not needed in Emacs 28. That variable you found tells Evil which feature/package you want to use for an explicit redo command.

How to undo the undo
Had so many problems with this (once a month/week) and lost work... that I gave up and wrote undo-fu and undo-fu-session.

A Love Letter to Intellectualism
gnu.org - contains everything you need to research his philosophy.
stallman.org - personal website, contains a lot of opinion, but I absolutely respect this man in all what he says.
emacs.org (redirects to https://www.gnu.org/software/emacs/) - his non-philosophical work, one of two mainstream console text editors.

The KGB, the Computer and Me – The Cuckoo's Egg Story [video]
Forever, there was a file included in stock Emacs, `spook.el`, which could be hooked up to automatically add random strings of "interesting" keywords to each of your email or Usenet messages (in signatures, or in headers like `X-Spook`).

Looks like copyright date of 1988:

Try `M-x spook RET` in an Emacs buffer.

How to combine daily journal with general database of people, places, things, etc.
If you want to spare a couple of detours, you probably could start with Emacs Org-mode according to Greenspun's eleventh rule: "Any sufficiently complicated PIM or note-taking program contains an ad hoc, informally specified, bug-ridden, slow implementation of half of Org mode."

Using Common Lisp in Emacs
The whole cl-lib thing is a total disaster:
https://github.com/emacs-mirror/emacs/blob/master/lisp/emacs...
They added cl- as a prefix to each Common Lisp symbol.
FIRST is now called cl-first, CAAAR is now cl-caaar .
I would really prefer if GNU Emacs removes all Common Lisp functionality, instead of creating this really wacky stuff, with discussions about this topic every year.

GNU Emacs is a versatile, open-source text editor that offers extensibility and customization—a sort of self-documenting real-time display editor. Our thanks for the suggestion go to CartanAnnullator.

Proof of Concept clang plugin that automatically binds C/C++ -> Lua
Their DEFUN and DEFVAR macros for example let us define a function or a variable that will be available as a Lisp function, and can be used as an ordinary C function from the C code. Emacs is written in pure C99 language and works with both GCC and Clang I believe. We can just define a C function via macro, and it is auto exported and made available to Lisp. For example my first patch to Emacs was for this function (we added "count" argument to make it possible to skip enumerating files in a directory for the case when user code is just interesting if a directory is empty or not):
