I finally installed SleepWatcher, and used the .sleep script from this script on MacOSXHints. This combination makes my powerbook switch back to the multi-user login screen whenever it sleeps. This is great whenever I have to share the computer with someone else since I usually set up a quick user account for them.

The only deviation from the simple instructions was adding SleepWatcher’s default installation location to my global PATH variable. I store mine in /etc/profile, so I ran “sudo pico /etc/profile” and added “:/usr/local/sbin” to the end of the existing string. Everything else was the default install and process described on the MacOSXHints page.

A few random thoughts in no particular order:

  • Any device with a rechargable battery and a USB port should be able to recharge by USB trickle.
  • Online trading of out of print recordings should be encouraged.
  • There is very little moral distinction between trading MP3s and buying/selling used CDs.
  • iPhoto’s biggest shortcoming is not organizing still-camera movies
  • VHS is obsolete. Overdue.
  • iSync needs to support more phones, even if those phones have lousy firmware.
  • I would learn how to make polyphonic ringtones for my LG phone, but when I finally have time to learn how, I’ll likely already have a new phone which will play MP3s as ringtones. That’s going to be fun.
  • Wiggle-sticks just got more plausible.
  • A well crafted algorithm can be stunningly beautiful
  • Potatoes are beautiful
  • A good centering bit and jig beats a carefully aligned center punch
  • It’s been too long since I’ve spent any time with William Merritt Chase’s edges
  • The new MoMA is an absolute triumph. The building dwarfs it’s contents. Monet’s waterlillies have never been seen like this.
  • iMacs are a really good deal from Amazon.
  • Too many artists like to fall back on really tired cliches when answering simple questions.
  • I’m thinking about a complete concept-up redo of this site. Who knows when that will happen. I’m sort of glad I don’t have time right now.

Found this PDF via Google, it’s one of the best references for video formats, tape formats and other technical specifications for digital video I’ve seen in one place.

I started on a longish posting tonight and wanted to include some hand-drawn diagrams when I realized (again) how much I still hate the whole process of including images in web pages. Ten years later and it’s still just a total drag. I swear I originally got into computer graphics because I hated scanning physical art.

A remarkable collection of illustrated and animated Sorting Algorithms with links to Java source code. Seeing how Quicksort compares to other methods of sorting reinforces why it’s one of the most important algorithms in current use. This page has examples of Quicksort implementations in a bunch of languages.

Quicksort uses a recursive divide and conquor approach to sorting lists. It was created by Tony Hoare in 1960.

Here’s another QuickSort animation which shows exactly what is happening during the sort. It’s a little slow, but after watching one or two iterations, it’s very, very easy to see what is happening.

While I don’t understand how they measure the O(n) space optimization, I love the thinking that goes into these.

No church bells this year, at least none that seemed to correspond to anything. I walked by two fire stations; Engine 5 is across the street from my apartment, Ladder 3 is on 13th Street between 3rd and 4th. There was some sort of family lunch inside the ladder 3 station house, I passed by quickly not wanting to gawk. Engine 5 had flowers outside the door. There weren’t any earlier in the morning when we headed to the playground at Tompkin’s Square.

For much of the day I was trying to figure out why I felt a certain numbness to this anniversary. Today was another milestone in time, but September 11th, 2001 has never left me. Earlier I looked at several photos and read a few stories which hardened the pit in my stomach, but in some ways it felt like I was forcing the pain. Maybe that’s what today is supposed to do.

I haven’t forgotten. There are constant reminders and, as one friend described it, there is “a certain low level paranoia about living in New York City.” I notice it most when I’m not here.

The Towers of Light are back and I can see them from our front window. I considered walking down to get a closer look and some photos, but decided to stay in and work instead.

Astounding realization: I went all

Astounding realization: I went all the way through college without ever owning a computer.
