Got a Raspi4 with 4 gigs of ram as a gift! Enabled a powerdown and powerup button<\/a> by adding dtoverlay=gpio-shutdown,gpio_pin=3<\/code> to \/boot\/config.txt<\/code>. Got fm_transmitter<\/a> maintained by markondej working. The project seems to be less complicated then PiFmRds<\/a> which I was using previously. Learning to add buttons, switches and sensors to the Raspi. Dreaming of adding a WH1602C-YYH-JTK# – LCD display too (I salvaged a unit in New York). Added a button using thagrol’s python script Switch button on GPIO, short press \/ long press<\/a>. A short press starts fm_transmitter and long press terminates it. This is done using scripts lauched from python subprocess.Popen(['\/home\/pi\/fm_transmitter\/broadcast.sh'],shell=True)<\/code>. I haven’t found a good way to terminate a broadcast, attempts to use pkill<\/code> cause the a segment of a broadcasted file to loop.<\/p>\n

Ilkka send me an interesting link K\u00e4sitt\u00e4m\u00e4tt\u00f6m\u00e4t koodirivit musiikkina [Incomprehensible lines of code as music]<\/a> (2014) Viznut (aka Ville-Matias Heikkil\u00e4) which introduced me to bytebeat.<\/a> The text also gives a thorough introduction to Demoscene development culture. Bytebeat is a music programming method which produces rhythms and melodies in complex ways users don’t seem to completely understand. It can be used online<\/a> (here are some samples for experimentation<\/a>). There is a tutorial of sorts available Discovering novel computer music techniques by exploring the space of short computer programs<\/a> (2011) Viznut. Also read Reaching for the blocks of the living world<\/a> (2018) by the author which feels like an attempt to bridge coding (optimization) and permaculture (degrowth?). The text explores two modes for studying: analytical mode vs. intuition. Viznut argues that “The trial-and-error mode is not problematic per se, it just needs a lot of cycles”.<\/p>\n

As a child, I used to believe in endless linear progress. There were ever higher buildings in the world, ever more TV channels, ever-faster computers and spacecraft. [\u2026] In my teens, I started to notice the dark sides. [\u2026] As a response, I started to embrace an opposite kind of esthetic and technological ideology: small is beautiful, bits are beautiful, hacks are beautiful. True progress is about deepness and compression instead of maximization and accumulation.<\/p><\/blockquote>\n

Viznut has also made the PC-lamerit online series<\/a> (2015-2019) which I’ve been browsing last night.<\/p>\n","protected":false},"excerpt":{"rendered":"
