io’s ‘cognitive innards’ (algorithms and source code).

source code 05-12-2009

By Han-earl Park | Published: July 1, 2009

Source code for io 0.0.1 beta (rev. May 12th 2009) [86kB zip file]. There have been major changes since 03-23-2009 as a result of the beta tests with Bruce Coates and Franziska Schroeder. These changes are unfortunately not documented/commented at the moment, but I’m uploading the source files for the record.

analog io

By Han-earl Park | Published: June 29, 2009

I’ve assumed that future versions of io would have a single board computer (or multiple SBCs) in place of the clunky and fragile personal computer. There was, however, always an alternative. Take the not-so-humble analog computer, a technology with a fascinating past and a (still promising) future. Given that io’s behavior is driven by an N-body [...]

beta test 11-10-08 & 12-08-08: resultant changes

By Han-earl Park | Published: March 25, 2009

Here’s a list of the significant changes. These address issues that Franziska Schroeder and Bruce Coates brought up during the testings in November and December respectively. Greater variation in output. Including pseudo-Braxtonian ‘separation’ implemented via interp tables. Implementation of a meta-banalyzer that shakes up the system depending on input variation. Greater variation in the VL70m settings. More responsive to external [...]

bug fix: banalyzer+

By Han-earl Park | Published: March 24, 2009

Here’s a fix for a significant bug that I somehow didn’t catch (didn’t hear?) for several years. The side effect of the fix is that io is now significantly more responsive. \ banalyzer+ \ \ a "smarter" banalyzer class designed to works in conjunction with the \ parser classes. \ \ ob.banalyzer+ clears internal storage and stats after an ALERT: message \ [...]
