In this document, the author details their experience upgrading the Linux kernel on a Chumby 8 device from the old PXA166-based 2.6.28 version to a modern 6.x version. By part 8 of the series, all major hardware peripherals were functioning well. However, the author observed unexpectedly high CPU usage reported by the "top" command, with fluctuating readings of 100% user/system usage and rare instances of 100% idle or 0% usage

The passage discusses the evolution of timekeeping from natural celestial indicators, like the sun and moon, to mechanical clocks. Initially, these natural rhythms guided human activity, while later mechanical timepieces refined the concept of time. In the 17th century, tall case clocks began incorporating a representation of the lunar cycle to assist with fishing and nighttime travel, utilizing a simple mechanism with a rotating disk that displayed two moons. However, this mechanism does not accurately depict the moon's phases due to its flawed representation of

The article, written by Piotr Migdał, discusses the importance of understanding and utilizing vectors in data science, particularly regarding their application in artificial intelligence (AI). It draws a parallel between King Midas, who turned everything he touched into gold, and data scientists, who convert data into vectors. While vectors capture similarities between data points, the author cautions against blindly applying cosine similarity, which can lead to misleading results, such as mismatching questions and answers or focusing on superficial attributes like writing style

The author created a tool in TypeScript to extract level data and graphics from the Commodore 64 version of Bubble Bobble. They enjoyed revisiting familiar levels but sought to uncover more related data, such as platform graphics and monster positions, which required detailed analysis of the disassembled game binary. By using a debugger to check register values and studying the game mechanics, they discovered that platforms are represented as 1-bit bitmaps. Each level consists of 32 by 25 tiles, though only
