Chris Houser's Clojure/conj talk on why Clojure's exceptions destroy information as the stack unwinds, unlike Common Lisp's condition system, which can resume from the error site. He surveys the existing libraries that approximate conditions, explains why they don't compose with each other, and considers what a better design would look like.

A panel from the Lang NEXT 2014 conference on systems programming in 2014 and beyond. Language designers including Bjarne Stroustrup and Rob Pike discuss the topic, including C++ header compile times.

Timothy Roscoe of ETH Zurich delivers the joint USENIX ATC/OSDI 2021 keynote arguing that operating systems must reckon with modern hardware, which is a heterogeneous collection of processors, firmware and coprocessors rather than a simple machine. It shows how much runs below and beside Linux.

The first lecture in Martin Kleppmann's 8-lecture distributed systems series from the University of Cambridge undergraduate course. It introduces the subject, and accompanying lecture notes are available.

Jeff Bonwick and Bill Moore, the creators of ZFS, present 'ZFS: The Last Word in File Systems' at the 2008 SNIA Software Developers' Conference. They explain the design, including copy-on-write, checksumming and avoiding the write hole.

Aditya Siram introduces ATS, a statically typed ML-like language that compiles to C and offers type-safe pointer arithmetic and a full proof language. The Strange Loop talk shows off C interop, concurrency and verification features with non-trivial examples.

Aaron Hsu's FnConf18 talk asks whether APL needs a static type system. He argues that APL's expressiveness and rapid iteration already deliver the benefits usually credited to types.

A Kurzgesagt animation giving a big-picture tour of the human immune system, its organs, transport network, and the cells it produces every day. It accompanies their IMMUNE book.

Big Clive gives a 38-minute beginner's guide to identifying common electronic components and what they do. He keeps the maths minimal and aims to fill gaps for people just starting out.

Joe Duffy's RustConf 2017 closing keynote on his experience at Microsoft building Midori, an operating system written in a Rust-like safe systems language. He covers the technical and cultural challenges of applying those lessons to Windows.

A Microsoft Research talk on BetrFS, a file system built on B-epsilon trees, a write-optimized data structure. It covers WODS such as LSM-trees, how to design a file system around them, and benchmark wins over ext4 and xfs.

Marshall Kirk McKusick gives a talk at EuroBSDCon tracing filesystem and storage development from 1979 to today, using the BSD Fast Filesystem as the focus. It covers early disk-geometry optimization through later contiguous layout and small-file performance work.

An animation presenting a non-standard helical or vortex model of the solar system, in which the planets trail the Sun through space instead of orbiting in flat circles. The model is a non-conventional view that the author says differs from standard diagrams.

A sketch from That Mitchell and Webb Sound in which a caller learns that identity theft is, in effect, a bank robbery in which the bank blames the customer. It runs about two minutes.

Richard Cook's short Velocity 2013 talk on resilience in complex adaptive systems, arguing systems operate near the edge of failure and that the surprise is how rarely they fail. He presents a model of how pressures push systems toward failure boundaries.

CGP Grey explains Mixed-Member Proportional representation, the system used in New Zealand where voters get two votes. It covers how it differs from first-past-the-post.

Dr. Richard Cook, a physician and patient safety researcher, presents his ideas on how complex systems fail, at Velocity 2012. He argues for designing for resiliency rather than trying to exhaustively handle every failure mode.
