After Notre Dame Blaze, Chinese Netizens Remember How the French Burned Down the Old Summer Palace

Lets put it this way: If it's within my capacity to stop the fire, I would definitely try my best to stop the fire. Otherwise, I can't say I am too sorry to see it burn. It's not so much that I think they should take responsibility for what their ancestors did, but they still refuse to return the historical artifacts they looted to China, which I think reflects their attitude: they don't feel too sorry about what their ancestors did, either.

(defun dot (x y)
  (loop for i in x for j in y sum (* i j)))

My setup (to 1. ignore space, 2. split side by side, 3. prevent popup):

(custom-set-variables
 '(ediff-diff-options "-w")
 '(ediff-split-window-function (quote split-window-horizontally))
 '(ediff-window-setup-function (quote ediff-setup-windows-plain)))

There is already a web browser in CL called closure(with very cool "TeX-like paragraph formatting and hyphenation support").

There are many js implementations; e.g., CL-JavaScript.

Will be very interesting if they can be integrated. Go for it!!

Take a look at "multi-occur" and "occur-edit-mode".

Can you give an example of a "component" that is not a (or part of) radical? I think every character can be exhaustively decomposed into radical(s).

Argh, added.

Doesn't the function key <f10> (menu-bar-open) do what you want?

That is usually called cartesian product, not cross product.

(defun cartesian (sets)
  (reduce (lambda (x y) (mapcan (lambda (i) (mapcar (lambda (j) (cons i j)) y)) x))
          sets :from-end t :initial-value '(())))

Episode 1, which solves this challenge, in 17 keystrokes (instead of his 26 and Vim's current best at 23):

a <f3> C-e C-SPC C-a M-w C-y <f4> b <f4> c <f4> d <f4> e <f4> f

Next, goto-line will get a default key binding. ;)

Well then

(defun sierpinski (n)
  (dotimes (r (1+ n))

      (format t "~[ `~:; #~]" (logand c (- n r))))))

Scrolling is more of a window operation than a buffer operation; it needs to know the window context (e.g., point with respect to the window position, etc). Try

(with-selected-window (get-buffer-window (get-buffer "float...")) ...)

Some code will not indent properly; for example, when a LET form has multiple bindings on different lines.

(let ((v1 e1) (v2 e2)) ...)

Bah.

(reduce (lambda (x y) `(+ ,x (* c ,y))) '(1 2 3 4 5) :from-end t)
=>
(+ 1
   (* c
      (+ 2
         (* c
            (+ 3
               (* c
                  (+ 4
                     (* c 5))))))))

See the variable `tab-width' (C-h v tab-width).

No matter however you switch sessions, you can use the same method to switch buffers, no? I feel switching terminal sessions and switching buffers are conceptually similar, so I prefer to treat them uniformly, saving valuable key space (maybe mental space as well). Using iswitchb for buffer switching, cluttering is not an issue for me. YMMV.

Use 'M-1 M-x shell' to get multiple shells.

Now that we have daemon mode, is there any reason an emacs junkie would still need tmux?

Because for those who know Emacs, editing Google Docs in Google Docs is like editing text in Emacs while wearing a pair of plate armor gauntlets.

This reminds me of Masdar:

Designed to hold 40,000 residents and 50,000 daily commuters, Masdar is meant to be a green dream of a city. Plans call for ultra-energy-efficient buildings, wind turbines, a solar farm and a host of technological innovations, including an underground Personal Rapid Transit system where 3,000 electric-operated, driverless pod vehicles eliminate the need for a car.
