So then all I have to do is add the following field to his record:

Emacs. One crazy idea at a time. Now I can use this to select random
information, like my favorite networking books or a list of my
upcoming events…

Random Emacs symbol: sort-coding-systems-predicate – Variable: If non-nil, a predicate function to sort coding systems.

• Emacs: Keep track of messages sent
• BBDB pinging code

I should write a small book about how to build a contact management
system with Emacs. ;) It's insanely powerful, you know.

(require 'planner)
(require 'bbdb)
(defun sacha/bbdb-show-only-no-contact-since (date)
  "Show only people who haven't been pinged since DATE or at all."
  (interactive (list (planner-read-date)))
  (let ((records bbdb-records)
        new-records
        last-match
        omit
        notes)
    (while records
      ;; Find the latest date mentioned in the entry
      (setq notes (or (bbdb-record-notes (caar records)) ""))
      (setq last-match nil omit nil)
      (while (string-match
              "[0-9][0-9][0-9][0-9]\\.[0-9][0-9]\\.[0-9][0-9]"
              notes
              (or last-match 0))
        (unless (string> date (match-string 0 notes))
          (setq omit t)
          (setq last-match (length notes)))
        (setq last-match (match-end 0)))
      (unless (and last-match omit)
        (add-to-list 'new-records (caar records) t))
      (setq records (cdr records)))
    (bbdb-display-records new-records)))

One of the other things I'd like to smooth over is keeping track of
who owes whom e-mail… <laugh>

It should be really easy to set up Gnus to expand some kind of
!followup macro into a TODO item in my planner and an “I hope to hear
from you by ….”. Ridiculously easy with Emacs Lisp and an insanely
customizable editor, but I might not have enough battery life. I've
got 28 minutes, and then I'm off PC for a while.

Step 1. Position the laptop face-down on one page of the photo album
so that the strip that keeps the plastic attached to the book is along
the top edge of the laptop lid. Trace laptop outline onto one page of
the photo album. (If you feel particularly diligent, you can measure
it instead.)

Step 2. Cut the photo album page to size. Trim a bit off the bottom
part to avoid hitting the laptop hinge.

Step 3. Attach double-sided adhesive tape to the laptop.

Step 4. Mount photo album piece on laptop.

Step 5. Peel back plastic and put in stuff.

I like this approach because it doesn't require me to bring any
special supplies in order to add to the display. For example, I can
add fortunes from fortune cookies, Post-it notes, or even business
cards.

This is handy for my wild idea about selling advertising on my laptop. This laptop hack's primarily about creatively expressing yourself, though. =)

Good stuff.

I came up with a terrific plan B: a whiteboard with a plastic
protector to keep it from being erased in one's backpack. That one's
pretty cool, too. I'll blog about it more on Sunday, Aug 27. In the
meantime… enjoy!
