Dan Worrall explains when higher sample rates help in recording and mixing, and when they do not. He goes into oversampling versus higher sample rates, and aliasing in distortion plugins.

A three-hour PyCon 2016 tutorial by Christophe Pettus that orients Python developers to PostgreSQL. It covers installation, administration, and use, including vacuuming, MVCC, replication and backups.

Russ Cox gives a 23-minute tour of the Acme text editor from Plan 9, showing its mouse-driven interface, executing commands from text, and its filesystem-based interface to other programs.

The first part of Robert Baruch's series on building a 6800 CPU on an FPGA with nMigen, a Python-based hardware description language. It introduces the HDL while implementing a simpler 6800 core.

Anders Brownworth gives a basic visual introduction to blockchain using an interactive web demo, covering SHA256 hashes, blocks, chains, distribution, tokens and coinbase transactions.

Jacques Pepin demonstrates deboning a whole chicken, quickly and with complete control. It is a short, wordless-feeling technique demo that shows a skill most cooks never learn.

George Brocklehurst of thoughtbot demonstrates Vim's built-in completion mechanisms, from word, line and block completion to ctags. The aim is to type less and make fewer typos.

The first stream in the Emacs From Scratch series, building a custom Emacs configuration from zero while teaching basics. It covers a usable baseline setup and the packages for completion, themes and productivity.

Kristy Viers demonstrates the iPhone Magnifier combined with VoiceOver to describe the user's surroundings. She shows how the built-in feature reports scenes, faces and lighting.

James Hoffmann demonstrates his AeroPress technique with a short recipe: 11g of coffee, 200g of just-boiled water, a 2-minute immersion, then a press. He explains why he skips rinsing, preheating and inverting.

James Hoffmann demonstrates his technique for a clean, sludge-free cup from a French press: stir, break the crust, wait, and carefully pour. It is a four-minute guide.

Harry Schwartz gives a roughly hour-long tour of Emacs Org mode as an outliner, task manager, markup language and agenda tool. He demonstrates how he uses it for documents, presentations and todo lists.

A 100-minute tutorial from Phil's Lab on designing an STM32-based 'black pill' PCB in KiCad 6. It covers schematic capture, two-layer layout and routing, USB, and sending the board for manufacture and assembly.

Markus Triska tours Prolog's most distinctive features, including its use as a database and query language, rule processing, constraint solving and compile-time rewriting. It also covers concise meta-interpreters.

James Hoffmann demonstrates his recommended technique for brewing coffee with a Hario V60 or other cone-shaped dripper, with notes on water and filter papers.

Marco Baringer's tutorial video on SLIME, the Emacs mode for developing Common Lisp. It demonstrates the interactive workflow of working against a live Lisp image.

Matt Risinger demonstrates a blower door test on a house, using a fan to measure air leakage and find where air gets in and out. It shows how the test reveals the quality of the build.

Tech Ingredients shows how to build a liquid panel with a specialty paint that, placed outside, cools below ambient air temperature. It demonstrates radiative sky cooling.

Ben Krasnow of Applied Science shows how to make and test YBCO high-temperature superconductor with a kiln and eBay chemicals. He demonstrates flux pinning and shows a close-up of the crystal structure.

Chef Chris Young shows a simplified triple-cooked method for making crisp frozen fries in an air fryer, based on Heston Blumenthal's technique.

Andreas Kling live-codes a prototype JavaScript JIT compiler for the LibJS engine used in SerenityOS and Ladybird. He builds a standalone bytecode VM, a simple interpreter, and then a simple JIT in about 80 minutes.
