Xah Lee, 2011-04-20Second Life is The Worst Software PossibleSecond Life is the worst software possible since 2000s. I can't start to list the problems. The whole design, every aspect, sucks major. Crashes every few hours, for the past 4 years.Yesterday i did a project of scripting teleporters for a guy.

Perm url with updates: http://xahlee.org/math/solids_of_constant_width.htmlGeometry: Ellipses, Linkages, and Solids of Constant WidthXah Lee, 2011-04-20Various very interesting mathematical objects. In particular, it shows various shapes based on properties of Ellipse, and various linkages. Peaucellier Linkage, and Hart's Linkage, based on properties of Geometric Inversion. (see: Geometric Inversion). What's interesting about these linkages is that they are mechanical means to convert between circular motion and straight line motion, important in the industrial revolution era. (think of the linkage on the wheels of steam-powered trains) The video alse feature curves and solids of constant width. Imagine, you can roll a book on top of several marbles. The marbles are spheres. However, there are also shapes that's not sphere but still lets you roll the book smoothly.Their website howround.com features these objects in more detail, also with a book How Round Is Your Circle?(20…
