gpu computing

Linus Tech Tips looks at whether buying a used GPU that was previously used for crypto mining is a good idea, as miners prepare to sell off cards. The video discusses how mining affects wear on cards and what to watch for.

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.

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.

Huygens Optics explains the Fourier transform and shows how a lens performs one optically. A DLP projector is used as a Fourier filter to do simple pattern recognition on lithographic character patterns.

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.

Dave Plummer tours the IBM z16 mainframe from design through factory assembly, test lab, accelerators and water cooling. He explains why mainframes still exist and what makes them reliable.

Quanta Magazine explains the 2022 experiment that claimed to create a holographic wormhole on Google's quantum computer. The description now notes that a later independent analysis questioned whether any wormhole was created.

Modern Vintage Gamer explains why PlayStation 1 graphics warped and jittered, comparing it with the Nintendo 64. The causes are affine texture mapping and the lack of sub-pixel vertex precision.

Veritasium's explainer on Godel's incompleteness theorems and the limits of mathematical proof, tracing set theory, Hilbert's program and the road to Turing and modern computing.

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.
