PCB devboard the size of a USB-C plug
AngstromIO is one of the smallest devboards out there, barely longer than a USB-C connector, based on the Attiny1616 MCU. 2 GPIOs as well as I2C lines are broken out. I made a dual CH340 programming board too, both for UPDI programming and debugging (one way Serial Communication). I also designed a breadboard friendly, experimentation […]

It seems that PyPy is not being actively developed anymore and is phased out even by numpy (numpy/numpy#30416). There’s no official statement from the project, but the numpy issue is from a PyPy developer. I added a warning to avoid users assuming PyPy properly supported and developed Python distribution.
Pushing and Pulling: Three reactivity algorithms
Contents Contents It’s looking like I’m going to need to build a reactive engine for work, so I’m going to prepare for that by writing down what I know about them. I want to look at three ways of building reactive engines: push reactivity, pull reactivity, and the hybrid push/pull combination that is used in […]
Science Fiction Is Dying. Long Live Post Sci-Fi?

Although sci-fi looks healthy from a perspective of films, video games, and TV, written sci-fi has long been the wellspring of the vast majority of new ideas, aesthetics, movements, and tropes within […]
