06:27:46 <tangentstorm> I finally added some instructions for building the pascal version here: https://github.com/sabren/b4/

06:56:52 <crc> the djb2 hash in library/hash.rx has too many collisions in the default config
07:17:05 <tangentstorm> well that's no fun :/
07:18:50 <tangentstorm> hmm. well, instead of a hash you could use the colorforth scheme
07:21:00 <tangentstorm> basically he maps every letter to a 5-bit code and shifts it, so instead of a hash it's a compressed representation of the actual word
07:21:59 <tangentstorm> so in 1 32-bit cell you'd have up to 6 letters, i guess.
07:22:50 <tangentstorm> or you could just go 8-bit, store the name in 2 cells
07:22:57 <tangentstorm> as actual ascii
07:23:49 <tangentstorm> limit identifiers to 8 characters, at least for the comparison
07:25:25 <tangentstorm> i know ascii's 7-bit, but if you go 8-bit then the image would actually be readable in a hex editor
07:26:24 <tangentstorm> actually then you can leave the lookup code exactly as-is. you just pad the name with zeros to fill out the last cell
07:27:04 <tangentstorm> the dictionary gets *smaller*, and you're testing 4 characters at a time (assuming 32-bit cellsize is) so it's faster than it is now too
07:28:02 <tangentstorm> you'd only have to pay the price to unpack the names in the disassembler
07:31:14 <tangentstorm> (and you'd still take a small hit when you compile, but the encoding's just:    dup 8 << getc 255 and and    or something, and that's got to be faster than a hash routine
07:31:29 <tangentstorm> )  :)
