I've been occupied recently with archiving my digital media. I've been copying home videos on DV tapes to hard-disk, ripping audio CD's to WAV files, gathering photo collections, and trying to copy documents from Iomega disks, floppies, and my dusty old Acorn RiscPC. The plan is to have a copy of this data to give to each of my children. My Dad recently scanned and sent me all his photographs of me and my siblings growing up; he also included pictures of himself and my Mother when they met in Africa. With technology today each generation can build a digital library of family history to hand on to the next generation. In the past a family album may have been passed on to only one person. The accumulation of digital data still presents problems. It requires discipline to store files that are open and not locked into devices or proprietary formats. With digital preservation in mind I've tried to use file formats recommended for long term archiving. WAV files for audio, D
NAME lab 107 - midiplay NOTES Midiplay plays back MIDI files. It uses the synthesizer I described in lab 62 and the MIDI module from lab 73. The command takes only one argument, the path to the midi file. I've included one in the lab to demonstrate. Bind the audio device before using it. % bind -a '#A' /dev % midiplay invent15.mid The synthesizer has 16 note polyphony. It uses three oscillators, one at the pitch, one at half pitch, one at double pitch. There is also a filter, two delays and a vibrato. The sample rate is 8000hz and there is one mono channel (MIDI channel events are ignored). It performs well enough to work on my laptop without JIT turned on. All the synthesizer parameters can only be tweaked from inside the code at the moment. FILES lab - 107
How is culture relevant to the training of artificial intelligence? A guess about the origin of human level intelligence is that it was mutually arising with complex society and culture, that is, with the origin and evolution of memes (Dawkins). Culture is composed of memes which are replicated by the two step process of being (1) recreated within a mind and then (2) enacted as some observable trait; creativity being necessary to reverse engineer the latent content of a meme, its meaning, in or order to accurately output the observable trait (Deutsch). A human using creativity serves memes as a kind of “meme machine” by making high fidelity copies of cultural artifacts or traits such as manners, rituals, totems, and tools (Blackmore). The complexity of cultural artifacts has grown exponentially from stone tools to space telescopes. Culture is a deep library of memes carrying objective knowledge. That knowledge contains within it truth about the world, while also being riddled with err
