Bezitopo will be a CAD program designed for land surveying.
PerfectTIN takes a clean point cloud of terrain, computes a surface (TIN, triangulated irregular network), and draws contours. PerfectTIN is almost ready for releasing version 1.0, but needs beta ...
Wolkenbase classifies a point cloud into ground and non-ground, using the lower sheet of a hyperboloid.
Wring is a whole-message cipher; Twistree is a keyed hash function with a double-tree construction. Both use the same key schedule and three same of the four round steps.
Daphne is a self-synchronizing byte stream cipher which recovers from deleted or inserted ciphertext bytes as well as from corrupted bytes.
Kaftor is a keyed affine transform, a kind of whole-message cipher which may be useful in secure multiparty computation.
Mumzel encodes 32-bit words in 36 bits, half of which are ones, with at most 11-bit-long runs. Its code rate (8/9) is greater than that of 8b/10b (4/5), and unlike 64b/66b is guaranteed to be a bal...
Propolis is a hexagonal 2-dimensional code which looks prettier and may achieve higher density than QR code when printed. It can also be serialized and used for outer space communication; framing c...
Mirasol is a program for teaching children numbers and sequences of numbers.
Quadlods (quadratic low-discrepancy sequences) is a C++ library which computes low-discrepancy sequences in up to 6542 dimensions (the number of primes less than 65536). I originally did Richtmyer ...
