Kyle McDonald shares a “bottom-up” estimate and tracker of Ethereum emissions and energy use that considers key variables such as hashrate and hashing efficiency, hardware and data centre overhead, grid loss, and power supply efficiency. According to the artist’s analysis, the popular cryptocurrency network consumes around 23 terawatt hours per year—as much as the entire state of Massachusets. “Ethereum is effectively operating two to three coal power plants,” McDonald writes on Medium.

Software engineer and electronics hacker Ian Hanschen shares his vast bitmap font collection that he pulled from various demoscene archives over the years. The catalog includes hundreds of glorious pixel letterform sheets created on the Commodore 64, Atari, and Amiga home computers in the late 1980s and early ’90s. “I don’t remember where much of this collection came from,” Hanschen writes about the missing metadata. “I just thought after finding a few of these [archives] had died that I should make it available.”
