learn-x-by-doing-y VS GNU Emacs

This list is enough, but after you get the basics from one of the above, do a project from https://aquadzn.github.io/learn-x-by-doing-y/

Some other knowledge-graph type projects for comparison:

> Metacademy - "Package Manager for Knowledge" - https://metacademy.org/

> MathLingua - language for easily creating a collection of mathematical knowledge, including definitions, theorems, axioms, and conjectures, in a format designed to be easy and fun to read and write. - https://www.mathlingua.org/

> Learn X in Y minutes - https://learnxinyminutes.com/

> Learn X by doing Y - https://aquadzn.github.io/learn-x-by-doing-y/

Many people are also starting to use the bidirectional-link style of note-taking to create their own knowledge graphs. I'm curious to see what sort of tools will emerge in the future to help people share the graphs they've created.

You see, I really needed something to do. I had been doing a few web related projects on the side and that was something I didn't want to do any more, at least for a while. So I looked into doing something "closer to the metal", something much lower level than sending requests back and forth to a web server. So I quickly fired up Learn X by doing Y and searched for something interesting, eventually ending up on Building your own Lisp (We all have a Lisp phase, it was just my turn).

Search is good, but if you're like me and would like to just see the list of available projects, it's here

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.

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:

https://github.com/emacs-mirror/emacs/blob/master/lisp/play/...

https://github.com/emacs-mirror/emacs/blob/master/etc/spook....

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

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."

Emacs: winget install GNU.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.

Never too late to try! Take your time. Emacs will outlive us all. https://www.gnu.org/software/emacs/

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.

Emacs

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):
