Random Thoughts by Bob Jenkins
I solved precession. It does not require expending energy.
You can balance masses so it is all OK.
(June 2017) I have a collection of political proposals.
Table of Contents (internal links):
- Here's a hash table, code for perfect hashing, a good hash function for hash table lookup,
a FAQ, some theory, and code to search for new hash functions. I tried designing block ciphers and finding characteristics. I had an article published in Dr. Dobb's in September 1997.
Have the cryptographic pseudorandom number
generator ISAAC, a small noncryptographic pseudorandom number generator, a prize for breaking ISAAC, and ISAAC's background and theory. Also take some tests for randomness, and a table of orders of magnitude. Here are also some protocols and a unit vector generator.
- See some skits from Boy Scouts,
SQL tricks from Oracle,
some paper airplanes,
and some cartoons that I wrote in college.
- Look into
formulae for n-body orbit simulations,
code for the HOMFLY knot
polynomial, voting methods, choosing random passwords,
jenny for pairwise testing,
some error correction codes,
a an april fool's design spec,
and a web page for choosing colors.
- Consider perpetual motion machines,
a dirigiped design,
a scale model of the solar system,
a page on exploring orbits with Java,
a simulation of Cruithne
(a near-earth object),
of figure-eight orbits,
of binary star planetary orbits,
a set of noncolliding orbits,
some Dyson Swarms (pretty pictures!),
some methods for the n-body problem,
a description of the orbit applet used,
and a tentative itzu world.
- Home projects
- See my half bath,
a house design that will never be built,
a dollhouse that did get built,
some genealogical notes,
and a roof rack for
- Here is my autobiography,
a cong from the British Museum,
a comparison of JPEG and JPEG 2000,
a bit on software patents,
my mom's art,
and some early Bob photos.
