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.

The original magic Emacs garbage collection hack

is it just me, or LSP mode is very slow in emacs?
A lot of people use way higher values than 800 KB without any problems. As a matter of fact, I've been using 256 MB for a very long time, haven't noticed any issues with it. So I wouldn't call 1 GB madness, it can be perfectly fine in some cases, especially if one uses gcmh, so it has a high chance that GCs will happen when the user doesn't interact with emacs (I also setup emacs to do GC when emacs loses focus. This means that GC pause is invisible most of the time for me). I strongly prefer very rare, short GC pauses than microstuttering all the time. Also, some operations apply a lot of pressure to the memory system, and do hundreds of GCs with the default setting, so most of the CPU time is spent in the GC when these operations run. Increasing gc-cons-threshold makes such operations much faster which means less pauses.

Setting up a fundraiser for multi-threaded Emacs, any thoughts on this?
One possible solution is to switch to a LSP approach. You should also take a look at the garbage-collector-magic-hack package: https://github.com/emacsmirror/gcmh

Chosing an Emacs Distro on M1 OS X
If you experience some lag, my first advice would be to install the GCMH package. It basically changes the garbage-collection rules to ensure that most garbage collection will happen in small bouts while Emacs is idle. After installing it I've never had my Emacs lag on me. This wouldn't address the retina-display issues you mentioned, but I've never experienced those with emacs-plus.

Will we be ever seeing multithreading in emacs?
I've seen gcmh recommended as a library that configures the garbage collector for you. Not sure if it is truly a "one size fits all" solution though.

Configuring emacs
I’d add that for 1) beacon is a good package. For 2), this may be an issue where you have multiple emacs configuration files. This is a serious problem. 3) be patient, and use the magic GC hack. To add to that, you should probably set the GC threshold to be high. 4) projectile? 5)emacs -nw.

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`).

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.

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):
