A guest lecture Jon Gjengset gave at Two Sigma on using Rust for large, high-performance systems. It covers why Rust suits such projects, the Noria research database, a concurrent data structure used in it, and practical experience.

Dr. Michael Greger gives a live presentation on evidence-based weight loss, previewing his book How Not to Diet. He focuses on foods that aid weight loss while also supporting health and longevity.

Database pioneer Michael Stonebraker argues that 'big data' is really at least four different problems: big volumes with small analytics, big analytics, velocity, and variety. He comments on where each market is heading.

Numberphile's James Grime makes the case for base 12 (dozenal) over base 10, showing how twelve's many divisors make arithmetic and everyday fractions easier.

A DeepSec 2010 conference talk by Ralf Philipp Weinmann on attacking the baseband processor of mobile phones rather than the application processor. It covers how open-source GSM base stations make malicious-tower attacks practical against neglected GSM stacks.

Martin Kleppmann's Kafka Summit 2018 keynote asks whether Kafka can be considered a database. He covers event logs and related data-systems ideas.

Martin Odersky's JVM Language Summit 2015 talk argues that compilers can be thought of as databases. It describes design ideas for the Scala compiler and for developer tools.

Dr. Michael Greger presents his book How Not to Die at Google NYC, arguing that diet and lifestyle changes can prevent or reverse many of the top causes of death. He walks through evidence on whole-food plant-based eating.

Mark Rober makes a plant-based burger for Bill Gates and explains why meat production strains the environment. Gates also appears and discusses his worry about steel and cement.

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.

Everyday Astronaut's guide to visiting Starbase, Texas to see Starship, covering what and where it is, which areas close during launches, where to watch from, where to fly into and stay, and things to do.

An AWS re:Invent 2018 session on how DynamoDB was built as a hyper-scale NoSQL database. It discloses underpinnings of the service and how it is run for over 100,000 customers.

A 2006 Google TechTalk in which SQLite's author Richard Hipp introduces the embeddable, zero-configuration C database library. He covers its history, strengths and weaknesses, and where it beats client/server databases.

Martin Fowler's GOTO 2012 introduction to NoSQL databases: where they came from, their data models, how consistency thinking differs, and when to use them. He argues they won't make relational databases obsolete and introduces polyglot persistence.

Dropbox engineer Kevin Modzelewski gives a Stanford colloquium on Dropbox's history and the technical problems it faced scaling, including detailed database schema decisions.

Redis Labs and Tim Davis present RedisGraph, which uses GraphBLAS to treat graph queries in Cypher as sparse linear algebra for lower latency.

Avi Bryant demos Dabble DB, a web-based spreadsheet-like database for building apps without code. It shows how users can model and relate data through a smooth interface.

Martin Kleppmann's Strange Loop talk on database transactions, covering why they were dropped by NoSQL, their reputation for being slow, and newer algorithms that make serializable transactions perform and scale. It touches on consistency, linearizability and the CAP theorem.

A short product demo of Dabble DB, a web tool for importing, entering and manipulating structured data with little effort. It was built in Smalltalk and later acquired by Twitter.

Cuong Do of YouTube describes how a handful of engineers scaled the site, covering hardware, software and database scalability challenges during its rapid growth. The talk was given at the 2007 Seattle Conference on Scalability.

Michael Arntzenius's Strange Loop talk on Datafun, a functional query language that brings database-style querying into a general-purpose language. It discusses bridging database theory and programming languages.

A Clojure/conj 2014 talk by Lucas Cavalcanti and Edward Wible on four uses of Datomic. They cover HTTP caching, audit trails, mobile database sync and authorization, drawing on the immutable transaction log.

Ahmon Dancy of Franz Inc explains low-level programming in Common Lisp, including off-heap data structures used in AllegroGraph to manage memory outside the garbage collector.

A satirical animated dialogue in which a naive developer insists MongoDB is web scale while a database expert mocks him. It parodies the NoSQL versus relational debate.

The Academy's 2014 Sci-Tech Awards segment honoring Matt Pharr, Greg Humphreys and Pat Hanrahan for their physically based rendering work and book. The authors give a short acceptance speech that thanks Donald Knuth for literate programming.

A 2013 research demo of simulated bipedal creatures whose natural gaits are found by optimizing muscle-based controllers, with no motion capture or keyframe animation. It shows physics-based walking and running emerging from musculoskeletal models.

Tim Dodd of Everyday Astronaut tours SpaceX's Starbase with Elon Musk as guide. They cover the high bay, grid fins, Raptor V2, the HLS lander and stage separation, and Musk explains his engineering management process.

jan Misali presents an humorous but earnest case for counting in base 6 (seximal) instead of base 10 or 12, comparing the arithmetic advantages of each.

John Hughes, co-creator of QuickCheck, talks about property-based testing of hard systems. He shows production examples where it found very low-level bugs, including issues in the CAN bus standard.

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.

Turing Award winner Michael Stonebraker gives the 2018 Donald B. Gillies Memorial Lecture at Illinois. He discusses the gap between academic research and industry problems, publishing incentives, and the influence of large industry users on research.

Mark Rober and Jabril build an app that uses machine learning to decode baseball sign sequences. The video also explains neural networks in a simple, accessible way.
