For me, I could not understand TrackBack until I used it. As soon as I used it, I realized it was an alterative way to adding a lengthy comment. (At least that is one obvious use of it.)

Kelly posted an article and enabled the “Allow Pings” option.

This made a “TrackBack (0)” link appear next to the “Comments (0)” link. Clicking on the TrackBack link produces a TrackBack URL that can be copied and pasted into the “Ping” field on my own blog article. By pinging from my article, my blog sends an update to Kelly’s blog, incrementing the link to: “TrackBack (1)”. Then, others can see I’ve posted a response, seeing my article title with an excerpt.

Very useful for an exchange of longer articles, giving the responding author the ability to fully edit the response. (Once you’ve posted a comment, you can’t change it.)

[Update: 6/20/2005. With 10.3.9 sendmail is configured to run “Automatic”. It just works w/ no configuration or fixes required. So notifications worked right away when I moved to the G3 running OS X 10.3.9.]

Sendmail quit working properly at some point. This meant notifications generated by MovableType were not being delivered. They were stuck somewhere.

This may have been caused by an Apple update of some kind. I think creating the NetInfo entry as described in on these pages is what finally solved the problem.

Kelly’s To Do List

Since Kelly says she is bored, maybe I can help! Here are some things to do:

1) Clean up her room.

2) Give Clyde a bath.

3) Wash Dad’s car.

4) Water the flowers.

5) Go on p–p patrol.

6) Figure out how this trackback stuff works!


Market Timing is way too complicated and no fun. Investing should be entertaining, not just about money. Whether you are buying a house and fixing it up, raising kids, starting a company, or owning shares, if it interests you then you are guaranteed a return on entertainment (ROE), even if you don’t get an ROI.

It also means you get to know your investments over time and can be smarter than the market who doesn’t know the investment. (I’m smarter about kids than I’ve ever been!)

My current strategy is to invest in known brands that fluctuate. I buy when they are artificially low (usually because of something in the news), and I know they can go up. I sell somewhere on the way up when I make 35% or more. I don’t worry about short or long term. I don’t try to get greedy and make more than 50% (anymore.)

I only invest in companies that I continuously read about and preferably experience their products as a consumer. This has worked for me with Intuit, Apple, ETrade, and Dell. I hope it is going to work with Microsoft and Home Depot. It did not work very well with 3COM who just melted down. I got out when the bad news stayed bad. I did not lose much because I only try to buy low.

What I’m banking on is that these stocks have more volatility because they are well known brands who create a lot of news which the media overhypes (in both directions.) Because so many consumers are directly investing now the market is more easily influenced by the hype.

“I can’t figure out what is going on with the market,” one of our board of directors told us in a meeting. “Prices go up and down when it doesn’t make sense.”

I’m banking on that, and so far it has worked pretty well.

Long URLs can be a problem because they can be broken up in e-mail messages and quit working.

I wanted to send a MapQuest URL showing how close the Morton’s live to Chastain park. (They get to listen for free!)

Using, I can e-mail this:

Instead of this:

Not sure how long it will really last, but good enough for short-lived URL needs. Thanks to Bill Crane for this tip!
