Child Safety Online Flier

FiT Child Safety Online Flier

A friend of mine has put together an educational flier on resources parents and caregivers can use to ensure that their children use the Internet safely. Topics range from cyber-bullying, blogging and street smarts for web surfing. There are also links to the popular free security software packages and office suites. And, last but not least, there are links to a couple of family friendly podcasts.

GPS photo tagging experiment

I recently bought a Garmin eTrex Vista Cx and like every new toy, I’ve got to play with it until something breaks. Until then, I’ll squeeze in some useful work. Using Robogeo to geocode the location info onto my photos, I’ve assembled a quick and dirty Google Map page. Most of these are just some shots taken from the car at various intersections to see if the location is close enough for more detailed uses.

Here’s some thumbnails of the pics I took. They link to the originals, which are rather large, especially the photostitched ones.

Penny bridges

I first saw coin structures like the ones atcoinstacking.com a couple of years ago, but it’s still a fascination for me. Like an arch, these only things holding the structure together is gravity and friction. But unlike that most ancient architectural element, there is no strategically placed keystone. These coin structures are also much more easy to build because the structure is relatively stable during construction.

I like the way this guy kept stacking more columns of coins on a bridge spanning three coin diameters. It’s amazing when you think about how the load is carried to the ground. Notice that in the picture before collapse, the bottom-most penny at midspan doesn’t appear to be carrying any of the load above it.
