Author JL Collins discusses his book The Simple Path to Wealth at Google, covering avoiding debt, simple index fund investing, and retirement accounts like 401(k)s and IRAs. It is an hour-long interview in plain language.

Bill Gurley's talk at the All-In Summit 2023, titled 2,851 Miles after the distance between Washington and San Francisco. He describes how incumbents use lobbying and regulation to entrench themselves, followed by a conversation with the hosts.

Peter Schiff's November 2006 speech to the Western Regional Mortgage Bankers Conference, in which he warned an audience of mortgage bankers that the housing bubble would collapse. The clip runs about 73 minutes.

Michael Green of Thiel Macro presents a thesis that the growth of passive investing distorts how markets price new money flows. He ties short-term market behavior to longer-term demographic cycles and its effects on valuations and volatility.

Daniel Azuma's ElixirConf 2018 talk on whether Docker and OTP conflict. He shows they can coexist and uses Horde and DeltaCrdt, with a live tank-game demo, to keep state alive across container kills.

Facebook engineers explain why they abandoned the traditional MVC paradigm for a more functional architecture, introducing Flux and React. They use the unread-message-count bug as a case study of the problems of bidirectional data flow at scale.

Scott Wlaschin shows how statically typed functional languages, using F# examples, can model a business domain so that invalid states cannot be represented. The type system acts almost like an instant unit test at compile time.

A 32C3 talk dissecting Red Star OS, North Korea's state-built operating system. The speakers explain its internals and how it invades users' privacy, including file watermarking.

In an 11-minute TED talk, Ralph Langner explains how his team reverse-engineered the Stuxnet worm and worked out that it targeted industrial control systems, with a covert state origin. It is a compact look at cyber-forensics.

A three-minute clip in which Douglas Crockford explains why he allowed the JSLint reference implementation to be used for evil. It recounts the license clause and how corporate lawyers reacted.

Svelte creator Rich Harris explains moving reactivity into the compiler and language rather than tracking state at runtime, with a history of spreadsheets as reactive systems and comparisons to React.

Justice Antonin Scalia's opening statement at a 2011 Senate Judiciary hearing on the role of judges. He argues that the Constitution's separation of powers is what protects liberty, and that gridlock is by design.

Martin Kleppmann argues that databases are global shared mutable state and proposes treating them as an ever-growing log of immutable facts. Derived data such as caches, indexes and views is then built by stream processors like Apache Samza. The talk draws on Kafka and LinkedIn's experience with commit logs.

Rich Hickey's 2013 talk applies language-design thinking to whole systems, covering names, queues, data, failure, and the interfaces between programs. It ends with a call to action for building systems holistically.

Dan Abramov live-codes hot reloading with time-travel debugging at React Europe 2015, debuting Redux and its devtools. The slides themselves are driven by application state.

Joe Armstrong, co-inventor of Erlang, gives a funny and opinionated Strange Loop talk on the tangled state of software: build tools, package managers, entropy and the physical limits of computation. He argues for ideas like naming things by content hash and throwing away your first version.

Alan Kay's 2015 talk on the power of simplicity, arguing that systems become simpler by building on more sophisticated fundamental building blocks and that big research horizons drove invention at Xerox PARC. It ranges across computing, tools and scaling software.

Joel Grus's JupyterCon talk explaining why he dislikes Jupyter notebooks. He covers hidden state, trouble with reproducibility and testing, and how notebooks frustrate teaching. He shows his preferred workflow and what Jupyter could change.

Bryan Cantrill's Uptime 2017 talk on the engineering challenges of the stateful data path, including storage, firmware and hardware bugs. It uses the 'zebras vs. horses' diagnostic heuristic to explain why rare failures keep appearing.

Peter Alvaro's Strange Loop 2015 talk argues that query languages let you state what you mean, and applies that to distributed programming. It covers Datalog, Dedalus and the Bloom lineage for reasoning about distributed systems.
