Overview of the Khan Academy Library

I am at a loss for words:

I majored in Mechanical Engineering, which means I took as much advanced math as it was humanly possible without switching my major to Math Nerd. It was a lot of math, and about 99% of it was pretty damn painful, it all hinged on who was teaching the class and having the wrong professor meant a high C at the best (I was VERY lucky, I got some incredible professors too, but there were also a few that were, well, not good).
Now ANYONE can have access to all of this knowledge for free, they are posted on Youtube! These are so good that Bill Gates gave them a shout out, both him and his 11-year old son have been using these for homework.

The Khan Academy is a not-for-profit 501(c)(3) and they have produced over 1600 high quality educational videos on Math, Science, Economics and other stuff. Anyone can watch these videos, and they are structured so they can be used as part of a proper curriculum, not just for informal learning.

On sleep deprivation and Incan Monkey Gods

From: Dilbert comic strip for 08/03/1992 from the official Dilbert comic strips archive. I was trying to show this strip to a coworker who is dangerously toying with the harsh mistress that is Insomnia. What shocked me is how quickly I was able to look up the strip, which was published when he was just 11 years old, and two weeks before my just-out-of-college ass shipped out to US Army Basic Training.

The Black Hole

If this was a minigolf hole, you can't reach B from A. Ever. If this was a room lined with mirrors, and you lit a candle at point A, you can't see it from B, not even reflected. Update: I guess I didn't explain this all the way through. You can't reach B from A with just one stroke, there's no direct line between them, and there is no way to bounce the ball (assuming perfect conditions). Thanks to Ben for pointing this obvious error.

Add custom speed settings to your ifit map workout

Ifit.com allows you to build a workout walk/race/bike route simply by clicking on a Google Maps interface. You can then use a compatible ifit-enabled workout machine to recreate the route automatically. The problem is that the user interface still isn't final, so there are features in place that aren't exactly obvious. For example, if you create a workout your machine starts at 1 MPH, because that's the default. But how to set it to start at say, 3 MPH? Easy, just switch from map view to graph view: That button switches from the Google Maps interface to a chart that allows you to visualize and control effort: You can't change the elevation, this is fixed due to the geography that you selected. But you can drag the yellow (speed line) to change the speed of your device. What if you want to have segments at different speeds? Easy, just click and drag and it will break the line, and you can drag each segment of the line independently: ...
