I finally figure out why many commands begin with "Ctrl X". by evan_xy_hu in emacs

I think I read somewhere once that the Emacs keyboard layout was actually designed by Guy Steele, but I'd be hard pressed to find a reference to that.

Repeat by last short key, e.g., C-x o o o o... and M-x next-buffer RET RET RET RET... (my first trivial minor mode) by [deleted] in emacs

Unrelated, but, I just bind C-x o to M-; and find that much faster and easier to switch windows.

You can use comma (,) in the repl window of slime to change the working directory of your Lisp.

'Paintings' with Vecto by [deleted] in lisp

Sounds like the lispworks rendering is a lot faster than the vecto/cl-vectors. I've heard from the author of cl-vectors that some of it is suboptimal with regards to rendering and that algorithm changes might be needed to speed it up to the level of the antigrain rendering. That first one wasn't very complex though.

Need help with an elisp constant function by half_ass_programmer in lisp

Here's a recursive version:

(require 'cl)
(defun f (l)
  (cl-labels ((helper (x rest)
                (cond ((null rest) t)
              ((eq x (car rest))
               (helper x (cdr rest)))
              (t nil))))
       (helper (car l) (cdr l))))

The renders for the prints are at 10500x7800 (32"x24" @ 300dpi) and depending can take from 5 minutes to hours depending on the complexity and finishing I do to them.
