Nonpareil release 0.78
This is just a minor release to fix build problems. Two missing semicolons were added to src/kmly.y because some versions of Bison complained about them. The GDK initialization in src/str2png.c was replaced with GObject initialization, so that str2png doesn’t require … Continue reading

Hamming distance conjecture
Someone on Usenet asked how many code points are possible in 16-bit code with a Hamming distance of 5. This type of problem is relevant to error detection and correction. I conjecture that for a n-bit code (where n ≥= … Continue reading

First non-RPN calculator in Nonpareil
Thanks to a ROM image and code provided by HrastProgrammer, Nonpareil will soon support its first non-RPN calculator, the TI-57. Since non-RPN calculators (even the HP-01 and HP-10) aren’t really consistent with the name Nonpareil, I’ve decided to put them … Continue reading
