Our small planet, as seen from the ISS (International Space Station) HDEV cameras, but with a bunch of sAPL code overlaid on the image. I've been messing about with how I want the market characterization vector to look like - playing with ideas for using a boolean vector to describe subsequence mkt conditions - ie. what the NN will train to identify. Looked at xkcd cartoon #540. It has little boolean matrix in bottom right corner. So I use sAPL to translate. (sAPL is the Sharp APL interpreter that ran on an Amdahl - but converted to run on an emulator, which runs on an X86. With gDOSbox running on the iPad, emulating an X86 running DOS, sAPL can run on the iPad, on any Android device (it's in the Playstore - totally free, no adverts), and a zipped version is on my github account, which will run on any Windows version, in cmd shell. It will also run on Linux, under DOSemu (CentOS, Fedora tested). Tiny workspace, but accurate numbers. ) Since the sAPL quadAV (atomic vector) is from an EBCDIC machine, I had to write a "genascii" function to create the 128 long ascii vector. Probably one of the more silly things I've done in years. Since I wrote one to translate boolean to ascii, I had to write the flipside, to convert ascii to boolean. For those who are unfamiliar with APL, imagine a mashup of Perl with Python, and then boiled down to very bare essentials, and expressed using single-character greek letters, like mathematicians prefer. The language was conceived by Ken Iverson, implemented by IBM, and before spreadsheets and personal computers, was the #1 internal language at IBM. It also was the first language on the first personal computer, the IBM Scamp (Special Computer APL Machine Portable), released in 1973.
