Algorithms manipulating context-free grammars often face issues with left recursion causing nontermination. Left recursion in a grammar leads to infinite recursion when generating or parsing a string. Fixing this involves rewriting the grammar to make it right recursive, avoiding left recursion. A real-life example of writing a C++ demangler involved tackling left recursion in the […]
Fossil hunter Peter Bennicke recently found a piece of fossilized vomit at a coastal cliff in Denmark, dating back 66 million years to the time of the dinosaurs. This unique discovery consists of sea lily fragments in a piece of chalk, shedding light on the prehistoric food chain. Palaeontologist Jesper Milan described the find as […]

SanDisk High Endurance cards use SanDisk/Toshiba 3D TLC Flash. SanDisk MAX Endurance uses the same 3D TLC in pMLC mode. SanDisk’s lack of detailed specifications led to the need for reverse-engineering. The process to uncover chip information and the construction of a breakout board is detailed, including the analysis of test pads. Identification of the […]
The term “mainframe” originated from the frames that held early computers, with the evolution of its meaning shifting from being a part of a computer to being a type of computer. The IBM 701 computer in 1952 was the earliest to use the term “main frame”, consisting of various frames with the main frame holding […]
YouTube is widely used for watching various types of videos, including audio recordings. The debate over the quality of audio on YouTube has sparked curiosity. The RVWSoc provided source files for two examples, revealing different audio streams offered by YouTube.
