You might have first used UNIX a long ago but if you haven’t then here is x86 port to try it for the first time pretty easily on a virtual machine.
Start exploring using commands cat ~cd ed diff egrep file pwd size.
cd /etc
pwd
file passwd
cat passwd
UNIX’ers: how do I use less or more to preview a file?
Thank you Greg for the big correction here …
The documentation for delete-char suggests that delete-forward-char ought to be used for interactive use instead of delete-char
(global-set-key (kbd "C-d") #'delete-forward-char)
I can’t find the git 2.10 binary so I run
which git
/usr/local/bin/git
Excellent, found it.
And then I check it’s version to verify I am looking at the right version
/usr/local/bin/git –version
git version 2.21.0
Oops that isn’t what I wanted.
There must be another git getting loaded earlier in the search path.
Here is how to find out where all copies of git live
type -a git
git is /usr/local/bin/git git is /usr/local/bin/git git is /usr/bin/git
Look for the right git at version 2.10
/usr/local/bin/git –version
/usr/bin/git –version
git version 2.21.0 git version 2.14.3 (Apple Git-98)
I want the second one.
That is how to track down the location of a binary file on macOS that appears multiple times in the search path.
Nice video about setting one up.
Learned that it is pretty easy. Just need the transceiver, sdr, and laptop.
Sometimes I want to recreate the OCR layer in a PDF using PDFPenPro but the menu item is greyed out.
Here is how force a re-scan:
If you open the menu first like I did, then the menu item remains greyed out, oops 😮😢.
PDFPenPro is in the top five list of best software that I’ve ever used. Check it out.

Once you’ve been using Emacs for a while you end up using eval-expression a lot. 99% of the time I use it to make function calls. I never noticed before that it is kind of tedious to reach for S-M-; and then () despite using it so much. Here is a binding and a function definition that make it easier to use binding it close to home and inserting the round parentheses.
(global-set-key (kbd "M-;") #'my-eval-expression)
(define-key org-mode-map (kbd "M-;") nil)
(progn
(defvar my-read-expression-map
(let ((map (make-sparse-keymap)))
(set-keymap-parent map read-expression-map)
(define-key map [(control ?g)] #'minibuffer-keyboard-quit)
(define-key map [up] nil)
(define-key map [down] nil)
map))
(defun my-read--expression (prompt &optional initial-contents)
(let ((minibuffer-completing-symbol t))
(minibuffer-with-setup-hook
(lambda ()
(emacs-lisp-mode)
(use-local-map my-read-expression-map)
(setq font-lock-mode t)
(funcall font-lock-function 1)
(insert "()")
(backward-char))
(read-from-minibuffer prompt initial-contents
my-read-expression-map nil
'read-expression-history))))
(defun my-eval-expression (expression &optional arg)
"Attribution: URL `https://lists.gnu.org/archive/html/help-gnu-emacs/2014-07/msg00135.html'."
(interactive (list (read (my-read--expression ""))
current-prefix-arg))
(if arg
(insert (pp-to-string (eval expression lexical-binding)))
(pp-display-expression (eval expression lexical-binding)
"*Pp Eval Output*"))))
For the fun of it try naming your Emacs configuration and instance.
For example my configuration is named HELP, HELP Enables Literate Programming. This is the collection of everything I find helpful for Literate Org Mode. Its also the collection of every single bit of code that people shared to help me out. It helps a lot. But that is not what I called my editor.
I call my editor instance PIE, PIE Interactive Editor. It is fun calling it a name that I like instead of Emacs. Emacs means so many things to all of us. Even Spacemacs names it especially for them. What is PIE? The PIE Interactive Editor? But what is PIE? PIE Isn’t Emacs 😄(Joy)😮(Surprise).
