Learning more about emacs

October 29th, 2009
tech, programming  [html]
When I first started using emacs, I chose it because I figured I might someday want my editor to be able to to something crazy, and emacs had the best chance of being up for the crazyness. Over the past five years or so, this hasn't actually turned out to be the case: almost everything I've wanted that's at all complex has made more sense as a stand alone program. This meant I'd not even learned how to write new functions for emacs. So today I learned how. Each of these entries is separated by a little bit of code that looks like:
  <a name="2009-10-29"></a><h3>Thursday October 29 2009:</h3>
  <div class="pt">

    <h3></h3>

  </div>
    
I'd been typing this in by hand, but today I decided to automate this. It turns out emacs supports the unix date syntax, so my dates become something like "%Y-%m-%d" and "%A %B %d %Y:". Very handy. The rest is just inserting characters:
  (defun start-news-entry ()
    (interactive)
    (insert (format-time-string
       "  <a name=\"%Y-%m-%d\"></a><h3>%A %B %d %Y:</h3>"))
    (newline)
    (insert "  <div class=\"pt\">")  (newline)  (newline)
    (insert "    <h3></h3>") (newline) (newline) (newline)
    (insert "  </div>") (newline))
    
So now I can just do "M-x start-news-entry" and not delay my urgent news-thoughts with mindless formatting. Yay.

Instead of “I’m anxious,” try “I feel threatened”

cw: teaching to learn I have a long history with anxiety, and I’m pretty good at noticing when it’s happening. The problem is that I’m always anxious. Noticing anxiety doesn’t snap me out of anxiety– in fact, it often produces meta-anxiety, anxiety about …

Checkmate on blackmail?

It has been argued that blackmail should be legal if gossip is legal, and even that there are no good consequentialist counterarguments (!). I think this isn’t obvious because the disclosures incentivized by blackmail are systematically worse than gossip.…
