Google maps has a collaborate feature now that will let you make a map layer that you can share with a group or even the world. It works like a wiki, so anyone in the share list can edit, edd or remove any data point.

I'm monkeying around with it and trying to kick off a worldwide map of hackers. If you code--or just pretend to--click on this link and add yourself and your hacker friends to the map:

The term "fuck-you money" is used to describe the amount of money a person would need to accumulate in order to walk out on their job permanently and live free of responsibilities.

I put together a spreadsheet last night which describes how an average person can achieve fuck-you money realistically. Assuming you can be happy living on 1/2 of your income, investing the rest, your investment returns will exceed your expenses in 10 years, and within 20 you'll be making more off your investments than your entire salary.

This is also an experiment with a Wiki-style spreadsheet using Google Docs. Everyone has access to edit the sheet to plug in their own hypothetical numbers, or even create whole other simulation models.

Here's a cheap way to make a rangefinder with a laser and a webcam.

You adjust the laser to be parallel with the camera, but a few inches away. Then, you can measure how far the visible dot is from the camera's center to calculate the distance. Further from center = closer to object.

It's sort of like binocular distance estimation with a single camera!
