learning from data

Benn Jordan investigates infrasound and low-frequency noise from data centers, including xAI's Colossus and a crypto mine, and reports his own experiments on the effects. The video covers the health and community impacts on nearby residents.

Scott Manley examines why SpaceX, Google and others are looking at orbital data centers. He walks through the economics, heat rejection and solar power arguments, with links to the Lumen/Starcloud and Google Suncatcher papers.

Scott Manley explains the thermal balance of spacecraft and how a satellite could be configured to radiate away the heat from datacenter-scale computing in space. His rough numbers suggest it is feasible.

A roughly 3.5-hour Gamers Nexus investigation into rising PC component prices, driven largely by AI data-center demand for memory and other hardware. It draws on interviews with industry figures to argue that personal computing and ownership are being eroded.

Veritasium tells the story of the XZ backdoor, how a patient attacker became maintainer and nearly compromised SSH on Linux systems. It also covers free software history and how encryption in SSH works.

Benn Jordan details security vulnerabilities in Flock Safety license-plate-reading cameras and how easily they can be compromised. It includes citations from security researchers and discussion of police surveillance.

Noodle explores how retro pixel art was designed for CRT displays and why games look different on LCDs, with input from pixel artists and CRT researchers.

Patrick Boyle examines SpaceX's planned IPO at a roughly $1.75 trillion valuation. He covers the merging of other Musk companies, orbital data center claims and the fast-track index rules that may help the listing.

Chubbyemu presents a case study of a man who followed AI health advice, replaced salt with sodium bromide and developed bromism with severe neurological effects. It is told as a dramatized medical case by a doctor.

A 105-minute technical deep dive from Noise In Space evaluating whether Starlink satellites could work as synthetic aperture radar. It covers SAR signal-to-noise, amplifiers, antennas, duplexing, phased array beamforming and simulations of V2 Mini and V3 satellites.

A five-minute C-SPAN clip of Dr. Jared Cooney Horvath testifying to a US Senate committee that screen time, including in schools, harms children's learning and cognitive development.

LabCoatz uses mass spectrometry, with help from other science YouTubers, to reverse engineer the Coca-Cola flavor and builds a chemically-identical replica. The video walks through a year of work on the formula.

A short Anthropic ad from its campaign saying ads are coming to AI but not to Claude, using a comedic scenario about getting a six pack quickly.

Gamers Nexus benchmarks GPU gaming performance on Linux using the Bazzite OS, an exploratory first step toward establishing a Linux testing methodology. It compares results against Windows and notes where Linux still falls short.
