From the project README

An excerpt from the repository, fetched Nov 13, 2026.

Read the project’s introduction
I am a researcher and computer scientist. I used to work in San Francisco, then I traveled a bit, and I'm now in NYC starting Materialize.io. The following posts are in reverse chronological order: newest posts are first. The content of the oldest posts may no longer be correct (mostly those about pieces of software I've worked on, and their state at some time in the past), but they have been retained for posterity (and some humility). topics date title Timely 2026-03-19 Speeding up timely dataflow by 100x Columnar 2026-03-14 Improving columnar with Claude Columnar, Claude 2026-03-14 Making Field Access Constant-Time in Columnar Columnar 2026-03-01 A Toy Vectorized Interpreter Datalog 2026-01-01 The Demand Transform Datalog 2025-12-23 (Worst-Case Optimal) Relational Programming Datalog 2025-12-14 Evaluating Datatoad Datalog 2025-12-03 Worst-Case Optimal Datalog Datalog, Columnar 2025-11-21 Columnar Worst-Case Optimal Joins Datalog 2025-11-17 Accumulating mid-Join Datalog, Columnar 2025-10-24 Columnar Datatoad Datalog 2025-10-09 Interpreted Datalog Check-in Materialize 2025-09-22 Programming with time in Materialize Datalog 2025-08-24 Checking in on Datatoad Datalog 2025-08-02 Comparing Interpreted Datalogs Materialize 2025-07-21 Materialize R&D Hackathon Datalog 2025-06-03 Datalog in Rust Differential 2025-05-29 Binary joins can be worst-case optimal Timely 2025-05-10 Asynchronous All-Reduce Timely, Differential 2025-05-09 Timely and Differential on WASM Materialize 2025-04-27 Transaction Processing in the Data Plane Bluesky 2025-03-13 Exploring Social Trends on Bluesky McSherry 2024-12-23 A decade in review (2015 - 2024) Materialize 2024-11-25 Understanding Consistency in Materialize E-Graphs 2024-10-19 Understanding E-Graphs Columnar, Timely 2024-10-11 Dataflow and Columns and WASM, Oh My!
