Vim macros, the quick and dirty, and Vim on Firefox

The goods:
To record: To record "keyo' do your macroee stuff here" q
To use: @"key"

The blah, blah, blah:

Okay, so I am ready to create a new macro on vim, and then I realized that I forgot how to make one. :(

I found this entry on how to do it. The best part about it is that the author forgot to talk about how you turn off the recording, so then the possibility of recursively calling the macro while you are recording was brought up. Nothing makes you smile like a random encounter with recursion!

Switching the up and shift button on an Eee

I recently got an Eee 1000. Nice little computer. The one mayor problem was dealing with the keyboard. For some reason they decided to put the up button where the right shift button is in American keyboards. Very annoying if you can touch type.

Fortunately I found this blog http://opuculuk.blogspot.com where the author pointed to a link on the eeeuser site that gives you a script to switch them around. The script also switches where the up and down button is, which is a bit disorienting, but easier to deal than not having the shift key where it should be.

Electricity Unit Completed in a couple of hours!

Yesterday we got a curriculum to have a unit on electricity at Crunchy Granola Academy. Today we started it. it teaches about simple electrical circuits, and it contains a light bulb, a motor, an LED and a buzzer. It teaches also about insulators and serials and parallel circuits.

Well, we finished it in less than two hours. Alexander, my 3-year-old, got upset when we were done, and he said that he wanted more motor training. This means that the unit was a success. :)
