Reverse-engineering the Globus INK, a Soviet spaceflight navigation computer

righto.com — One of the most interesting navigation instruments onboard Soyuz spacecraft was the Globus INK,1 which used a rotating globe to indicate the spacecraft's position above the Earth. This electromechanical analog computer used an elaborate system of gears, cams, and differentials to compute the spacecraft's position. The globe rotates in two dimensions: it spins end-over-end to indicate the spacecraft's orbit, while the globe's hemispheres rotate according to the Earth's daily rotation around its axis.2 The spacecraft's position above the Earth was represented by the fixed crosshairs on the plastic dome. The Globus also has latitude and longitude dials next to the globe to show the position numerically, while the light/shadow dial below the globe indicated when the spacecraft would enter or leave the Earth's shadow.

U.S. Home Prices Are the Most Unaffordable They've Been in Nearly 100 Years

longtermtrends.net — Historically, an average house in the U.S. cost around 5 times the yearly household income. During the housing bubble of 2006 the ratio exceeded 7 - in other words, an average single family house in the United States cost more than 7 times the U.S. median annual household income. The Case-Shiller Home Price Index seeks to measure the price level of existing single family homes in the United States. Based on the pioneering research of Robert J. Shiller and Karl E. Case the index is generally considered the leading measure of U.S. residential real estate prices. The index has a base of Jan 2000=100 and is multiplied by 1800 in order approximate the Average Sales Price of Houses Sold for the United States. According to Mike Maloney this ratio is heavily influenced by interest rates. When int... U.S, 7

I Saw the Face of God in a Semiconductor Factory

wired.com — I arrive in Taiwan brooding morbidly on the fate of democracy. My luggage is lost. This is my pilgrimage to the Sacred Mountain of Protection. The Sacred Mountain is reckoned to protect the whole island of Taiwan—and even, by the supremely pious, to protect democracy itself, the sprawling experiment in governance that has held moral and actual sway over the would-be free world for the better part of a century. The mountain is in fact an industrial park in Hsinchu, a coastal city southwest of Taipei. Its shrine bears an unassuming name: the Taiwan Semiconductor Manufacturing Company. SAW, 11

An Interview with Nvidia CEO Jensen Huang About AI’s iPhone Moment

Things I’ve Learned from Charlie Munger about Moats (2015)

25iq.com — 1. “We have to have a business with some inherent characteristics that give it a durable competitive advantage.” Professor Michael Porter calls barriers to market entry that a business may have a “sustainable competitive advantage.” Warren Buffett and Charlie Munger call them a “moat.” The two terms are essentially identical. Buffett puts it this way: “The key to investing is not assessing how much an industry is going to affect society, or how much it will grow, but rather determining the competitive advantage of any given company and, above all, the durability of that advantage. The products or services that have wide, sustainable moats around them are the ones that deliver rewards to investors.” A complete discussion about the nature of moats can’t be done well in a ~3,000 word blog pos...

The fastest rm command and one of the fastest cp commands

alexsaveau.dev — BlogFast Unix CommandsThe world's fastest rm command and one of the fastest cp commandsPublished Mar 24, 2023 • Last updated Mar 25, 2023 • 2 min readFast Unix Commands (FUC) is a project that aims to create the world’s fastest Unix commands. Currently, this means rm and cp replacements named rmz and cpz (the ‘z’ stands for “zippy”). When better performance cannot be achieved, the next highest priority is efficiency. In practice, rmz appears to be the fastest file deleter available while cpz wins in most cases, only losing in flat directory hierarchies.Myth bustingMany Stack Overflow answers will tell you to use this or that as a faster alternative to rm or cp.

My experience crafting an interpreter with Rust (2021)

ceronman.com — Last year I finally decided to learn some Rust. The official book by Steve Klabnik and Carol Nichols is excellent, but even after reading it and working on some small code exercises, I felt that I needed more to really understand the language. I wanted to work on a small project to get some hands-on experience, but most of my ideas didn’t feel very well suited for Rust. EXPERIENCE, 25
