My hero! Shustek, APL/360 & 10 Years Later

Published on October 10, 2012 in APL/J/K The Movie, CHM, IBM 360 and Kenneth E Iverson. 6 Comments by aprogramminglanguage

It took Len Shustek, chairman of the board of trustees of the Computer History Museum in Mountain View, California, 10 years to get permission from IBM to publish the APL/360 source code. Not only has he gone and done it, he’s also written a wonderful companion explanatory essay to go along with its publication. Please see: The APL Programming Language Source Code

Congratulations, Len! Thank you for your persistence.

Just had a nice insight regarding systems that deal with reactively updating (potentially large, structured) values such as RDP:The dynamic output of a process is indistinguishable from a static storage resource (file).In batch systems like Unix, this symmetry is not so deep: the output stream of a process looks somewhat like a file, but the process […]

RESTful RDP with big values August 2, 2015
What if you want to use a big value, like a whole database table or weblog, as a Reactive Demand Programming signal value? This would make it possible to use RDP to orchestrate things like incremental MapReduce pipelines. Here's one weird trick to make it work.In effect, each RDP signal becomes a RESTful server, speaking an HTTP-like […]
