Summary from the TLDR Web Dev newsletter

A weird bug in an augmented reality system caused disorienting visual glitches and interestingly, only happened every Wednesday. After an extensive, months-long investigation involving robotic arms, lasers, and a high-FPS camera, the root cause turned out to be due to a time-translation hack using day-of-week words in German and English neglecting to account for the German word for Wednesday, "Mittwoch." This oversight led to timestamp discrepancies, resulting in the weekly glitches and an unpredictable error correction mechanism.
