Michael Saylor has publicly criticized Bitcoin Improvement Proposal 110 (BIP-110), calling it a “statist” approach to changing Bitcoin’s consensus rules. According to Saylor, the proposal attempts to restrict how Bitcoin can be used by limiting non-monetary data stored on the blockchain, such as inscriptions created by protocols like Ordinals. He argues that Bitcoin’s open design…

Getting an answer from ChatGPT after you ask it a question takes about 2 seconds, but the answer depends on a large physical infrastructure system operating behind the screen. In Leo Cui’s video, The Entire AI Data Center Explained — From Electricity to ChatGPT, he follows a request through what he describes as an “AI…

The race to build the world’s most powerful AI infrastructure has shifted beyond individual GPUs to complete rack-scale systems that integrate processors, networking, memory, and cooling into a single high-performance platform. Rather than selling standalone accelerators, companies are now engineering entire AI racks capable of training trillion-parameter models and supporting the next generation of reasoning…

Scientists connected to Harvard Medical School have advanced a genetic-reprogramming technique designed to restore more youthful patterns of cellular activity. The experimental approach uses three transcription factors—OCT4, SOX2 and KLF4, collectively known as OSK—to help older or damaged cells recover gene-expression patterns associated with healthier tissue. Harvard researcher David Sinclair has said that related animal…

There is no single electrical code, license, organization, or enforcement authority governing every electrical installation in the world. Electrical safety is controlled through a layered system of international standards, national laws, regional codes, local amendments, workplace regulations, product-certification requirements, utility rules, licensing boards, inspectors, employers, and authorities having jurisdiction. An installation may comply with a…

@1x.technologies just unveiled its next-generation robotic hand for NEO, the company’s humanoid home robot. The new hand features 24 degrees of freedom, tactile sensing, human-like dexterity, and enough strength to perform practical everyday tasks. NEO can pick up coins, operate tools, zip a jacket, pour tea, connect a USB-C charger, clean surfaces, and even wash…

OTDR, or Optical Time Domain Reflectometer, operates by injecting a series of short laser pulses into one end of an optical fiber and measuring the light that is scattered or reflected back from points along the fiber. This backscattered light—primarily due to Rayleigh scattering and Fresnel reflections—is captured by a photodetector within the OTDR, and…

The BitcoinVersus.Tech Open-Source Electrical Training Program is an independent technical education project built to study, organize, explain, and compare electrical standards and procedures used throughout the world. The project is designed around a simple idea: electrical knowledge should not remain trapped inside expensive textbooks, fragmented codebooks, institutional training programs, or specialized professional circles. The information…

Soldering is a metal-joining process used to create reliable electrical and mechanical connections without melting the primary components themselves. Its roots extend back to early metalworking, but soldering became especially important with the development of electrical systems, radios, printed circuit boards, and modern electronics. Image Source: @wirethinkers Today, it remains essential for electronics manufacturing, component…

A Visual Fault Locator (VFL) is a handheld optical testing device used in fiber optic networks to identify faults, breaks, or discontinuities in optical fibers. It emits a highly visible red laser light (usually around 650 nm) into the fiber, which allows technicians to visually trace the fiber path. Any break, bend, or poor connection…

Economist Peter Schiff has publicly criticized Michael Saylor’s characterization of Bitcoin as “digital energy.” Schiff questioned the practicality of using Bitcoin to generate power, contrasting it with crude oil’s essential role in preventing mass starvation. Michael Saylor, Executive Chairman of MicroStrategy, has previously described Bitcoin as “digital energy,” suggesting that it conserves energy in cyberspace…

VLANs, or Virtual Local Area Networks, are one of the most important building blocks in modern networking. A VLAN allows one physical network to be divided into multiple logical networks, giving administrators more control over how devices communicate. Instead of placing every computer, server, camera, printer, phone, and wireless device into one large flat network,…
