I created a simple command line utility [1] to convert between rotation representations. If anyone has ever dealt with 3D rotations (e.g., euler angles, quaternions, rotation matrices) you probably know that it can be frustrating to know what conventions people are using, especially with euler angles (e.g., intrinsic, extrinsic, passive, active, etc.). So I made a tool where you can explicitly set those conventions with explanations on what they all mean.

I regular refer back to the README myself or test out some conventions with the tool.

Yeah but the government is forbidding you from using your barn.
Re:What Is the Most Valuable Thing You Can Learn in One Hour? on Tuesday December 31, 2019 @08:48AM (#21920948)
To put it simply, it's just a very efficient way to manipulate text with a keyboard. Once you get accustomed to it, writing and especially modifying text without it seems laborious, almost like you're writing with your wrong hand.

The problem is, the opposite is true until you reach some level of proficiency. Until then, vim is hard to get used to.

I know I haven't provided a concrete answer, but many blog posts have been written on the matter. I personally started learning vim by running through vimtutor once a day as part of a New Year's resolution about ten years ago.

You can select the colour scheme from a menu in the bottom left (including several light schemes).

Love the site. I see the "Recommendation" header center-aligned, while all other headers are left-aligned. It looks odd to me, was this intentional?

Depending on your application, if you're interested in A* you may be interested in using Theta* instead. It's not much more difficult to implement but provides much shorter paths if one does not need to remain on the edges in the graph.

Take a look at the explanation and figures here: http://aigamedev.com/open/tutorials/theta-star-any-angle-pat... for more information.

You can test vehicles that don't have (internal) controls for a human driver (e.g., no steering wheel, pedals).
