Bryan Cantrill of Oxide Computer Company gives a Stanford EE380 talk on rethinking the server. He argues that hyperscaler-style rack-scale machines with open firmware, RISC-V and Rust should be available to everyone, not just the giants.

Veritasium explains why analog computing may suit AI workloads, covering old analog computers, The Analog Thing and Mythic's analog chips that use flash memory for neural network inference. It argues digital hardware is hitting limits.

Veritasium traces analog computers from the Antikythera mechanism and Kelvin's tide-predicting machines to fire control and modern analog approaches. It explains how these machines computed continuously rather than digitally.

Lex Fridman interviews Bryan Johnson, founder of Kernel and previously Braintree, about brain-computer interfaces and Kernel's non-invasive brain monitoring hardware. It covers what the devices can do today and the company's plans.

An Asianometry explainer on why the Soviet Union, once a leading computing power, fell far behind the US in computers by the 1980s. It traces the gap from the 1960s onward despite strong state support for science.

Scott Manley tells the story of a computerized telemetry system built to sit at the heart of a nuclear test device in place of the plutonium pit, designed to transmit data in the microseconds before it was destroyed.

The Little Britain sketch in which call-center worker Carol types into her computer and replies 'computer says no' to every request.

A 37C3 talk by Kaspersky researchers on Operation Triangulation, a zero-click iPhone attack that targeted their own colleagues. They describe capturing every stage of the chain, four zero-days and a previously unknown spyware active for years.

Jake Archibald argues that URLs are nearly impossible for humans to interpret, especially for security. He walks through what browsers do about it, including highlighting the registrable domain, and floats a possible better design.

Daniel Stenberg's keynote at FrOSCon 2025 on AI slop attacks on the curl project, with examples of bogus AI-generated security reports. He discusses the toll on maintainers and why various countermeasures don't fit the project.

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.

LockPickingLawyer examines a challenge involving a tamper-sealed Abus lock and shows how the tamper seal can be defeated.

Computerphile interviews AI safety researcher Rob Miles about ChatGPT: how it was trained with human feedback, why it tends to produce confident nonsense, and where it may or may not be dangerous.

A 36-minute animated deep dive from Branch Education into how DRAM works. It shows how memory connects to the CPU and how billions of bits are stored in nanoscale capacitor cells. It also covers why DRAM sits between SSDs and the processor.

Technology Connections takes apart a 1970 Wurlitzer 3400 jukebox to show how electromechanical relays and switches automated its behavior without a computer.

Veritasium explains how cosmic rays and other particles flip bits in computer memory, with examples including a Belgian election count error, plane incidents and game glitches. It is inspired by a RadioLab episode on bit flips.

SANS ICS Security's parody video of the HyperEncabulator, a spoof of the Turbo Encabulator technobabble videos.

A DEF CON 29 talk by Richard Henderson about encoding the EICAR antivirus test string into QR codes and barcodes and scanning them at real systems. Many systems that do not expect such input misbehave or collapse, including a parking garage system.

Engineer Stuff Made Here builds two new supposedly unpickable locks with different designs and sends them to the Lock Picking Lawyer to see whether they can be defeated. The video covers the novel anti-picking mechanisms.
