Dave Ackley demonstrates the Demon Horde Sort, an inherently robust sorting machine running in his Movable Feast Machine simulator. This is the uncut version with all details and side thoughts.

Casey Muratori follows up his refterm proof-of-concept, a GPU-based terminal renderer, with a second part covering memory usage, glyph sizing and correct Unicode and VT handling. It is built to show that a terminal can be fast and correct without heroic effort.

A two-minute 2008 clip from Sun's Fishworks team in which Brendan Gregg uses DTrace to show disk latency spiking while he shouts at a rack of drives. Bryan Cantrill narrates the demonstration.

A Samsung-backed viral demo that builds a fast computer from 24 256GB MLC SSDs in a RAID 0 array and shows the throughput results.

MattKC fits a playable Snake game into a QR code by writing tiny x86 machine code and patching the ZBar scanner so it can run the decoded data.

Dave Ackley presents robust-first computing and the ULAM programming language for the Movable Feast Machine, a cellular-automata-like architecture. It was a short video for the Future Programming Workshop 2015.

Casey Muratori captures CygnusEd Professional running on an Amiga 2000, showing how smoothly it scrolled text. He notes the real effect is better on a period CRT.

Der8auer tours Hetzner's test lab and shows a custom AM5 server motherboard with the CPU socket rotated 90 degrees, built for rack airflow in their AX52 servers.

LGR looks at the Silicon Graphics Indigo2, a UNIX workstation that cost about $86,000 in 1995, covering its pros and cons, games it can run, and whether it is worth owning today.

Linus Tech Tips opens up an M1 MacBook Air to test whether better thermal pads could improve performance in the fanless design. It looks at what Apple left on the table.

Nick Caston compares Unity's sample ECS/DOTS project (AngryBots) with his own from-scratch C++ and OpenGL clone. He benchmarks performance and discusses the effort involved in each approach.

A short tour of the Megaprocessor, a microprocessor built at enormous scale from tens of thousands of discrete transistors. The builder shows what the machine is made of and where it now lives, at the Centre for Computing History in Cambridge, where visitors can play Tetris on it.

A live-coded demo by Jonathan Blow showing how to get object-system-style expressiveness in a data-oriented way, covering structure-of-arrays layouts and composition. It shows features of his Jai language that make programs fast.

The winning demo from Revision 2015's oldskool competition, running on a real 1981 IBM PC with CGA at 4.77MHz. It uses extreme tricks to produce effects, graphics and sound far beyond what the hardware was thought capable of.

Der8auer visits Tescan and uses an electron microscope to compare real transistor sizes on Intel 14nm and AMD 7nm chips. It shows that process node names do not match physical measurements.

A short Princeton CITP video describing cold boot attacks, where encryption keys remain in DRAM after power loss and can be recovered. It covers the attack against disk encryption such as BitLocker, FileVault and TrueCrypt.

A short demo showing slow 2D drawing in the Windows 7 GUI compared with XP. It attributes the slowdown to the display driver model lacking hardware accelerated GDI.

Linus Tech Tips tests whether chaining many PCIe riser extensions causes loss of GPU performance. They keep adding extensions to see how far the signal will go.

Dave Jones of EEVblog tears down a 1991 IBM 9121 thermal conduction module from a System/390 mainframe, a 63-layer ceramic hybrid module with 2772 pins worth about $250,000, and demonstrates a BGA desoldering technique.

A short Microsoft promo comparing classic Teams with the rewritten new Teams side by side, claiming faster startup and better performance. The new version is shown taking around nine seconds to launch.

Linus Tech Tips replicates the Threadripper workstation Linus Torvalds built for himself, discussing the parts such as the CPU and cooler.

Linus Tech Tips water-cools a 2020 MacBook Air, tearing it down and showing the cooling design along the way. The video shows the gap between the CPU lid and die and how little the stock heatsink does.

Linus Tech Tips tests a Chinese mining-only Nvidia card, hacked with a modified driver so it can render games and output video through an integrated GPU.

Enderman gets Windows 11 running on a Pentium 4 system with a Radeon HD 5870 and 8 GB of DDR2. It explores how an unsupported, ancient CPU can be made to work by using the rare last Pentium 4 variant and a registry flag.

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.

Level1Techs' Wendell shows Intel's Flex 170 GPU providing GPU-accelerated virtual desktops on Proxmox 8.1 without subscription licensing, using SR-IOV, and demonstrates many desktop instances running at once.

A short side-by-side recording by Jake Archibald of the same animation demo running in Chrome, Firefox, Safari and Servo WebRender nightlies on a 60Hz display. It shows the smoothness difference of GPU-based rendering.

A short 2001 Tom's Hardware clip that runs Quake 3 on several popular CPU and motherboard combinations of the era, then removes the CPU cooler to see which chips survive. It shows how different processors handle losing their heatsink or fan.
