revised Which is better, odd/even Hamming codes or extended Hamming code?
clarify (I hope) that by "the even+odd Hamming code" I mean something that uses *both*.

comment Probability of the sum of n numbers giving the same last d digits
Practical application: When the transmitter adds d check digits or b bits of checksum to a message, what is the probability that the receiver will (incorrectly) fail to detect any errors in a random message?

comment Find points along a Bézier curve that are equal distance from one another
@Kenpachi: The Babylonian method gives you a bunch of "t" values. The x,y coordinates on the curve at any t is given by plugging that t value into the Bezier function B(t). For example, if we want the x coordinate at t=0.1 of a typical cubic Bezier curve with control points P0, P1, P2, P3, we calculate B_x(0.1) = (1-0.1)^3*P0_x + 3*(1-0.1)^2*(0.1)*P1_x + 3*(1-0.1)*(0.1)^2*P2_x + (0.1)^3*P3_x.

comment How do I find a Bezier curve that goes through a series of points?
The design guys are not the problem. The problem is that nearly every 3D CAD package stores curves in its own proprietary binary 3D file format. They are happy to "export" their designs to some other format, but apparently their only choices are (a) some other proprietary binary file format, or (b) a STL made of thousands of tiny flat triangle facets.
