A page from the book 1984

Brown University is home to George Orwell's original manuscript of 1984. Most of it is marked up heavily in Orwell's hand-writing but this untouched page caught my eye.

RIP Tracy Kidder, who inspired so many of us, and gave us permission to feel unapologetic passion for our chosen craft bcantrill.dtrace.org/2019/02/10/r...

In computing, we take imagination and make it manifest in the form of software and hardware.

Picture of Marjane Satrapi alongside a quote from her. The quote reads: The world is not divided into countries. The world is not divided between East and West. You are American, I am Iranian, we don't know each other, but we talk together and we understand each other perfectly. The difference between you and your government is much bigger than the difference between you and me. And the difference between me and my government is much bigger than the difference between me and you. And our governments are very much the same... - Marjane Satrapi, Iranian-French graphic novelist

Thinking about this quote from Persepolis creator Marjane Satrapi again.

Agentic engineering is driving the cost of code to zero but the cost of good taste and product sense is going to go sky-high.

A reminder to all military service members out there that “I was just following orders” was not a valid defense at Nuremberg and it won’t be here either.

I worked on a few fairly prominent efforts in open source (Istio, OpenAPI), but I think of all of them, it’s gRPC that I think has the coolest story. Pull up a chair and set for a spell (any inaccuracies in what follows are 100% my fault for having a bad memory!).

@booch.com The link to check architecture books is broken

LeaseGuard: Raft Leases Done Right! A new Raft enhancement for fast, consistent reads.

Raft has a real problem guaranteeing Read Your Writes, because there might be two leaders serving reads at once. In theory, you could use a timed lease to ensure there's only one leader.

Pedagogy Recommendations Parenthetically Speaking: Articles by Shriram Krishnamurthi

Over the years I've been asked many times for advice on pedagogy, what to read to learn more, etc. I've finally put together a bunch of materials into one blog post: Key Advice • Readings • Neuromyths • For Computer Scientists • Classroom Tips. Enjoy!

My colleague Sanjay Ghemawat & I have done a fair bit of performance tuning of various pieces of code. We wrote an internal Performance Hints document ~2 years ago as a way of identifying some general principles & we've recently published a version of it externally.

What defines a correct program? What education makes a good programmer? The answer depends on what culture of programming you subscribe to!

This has been a long time in the making, but my open access book on the history of programming is available for pre-order!

Ins and Outs of the Outbox Pattern, Gunnar Morling YouTube video by Bulgarian Java User Group

📺 "Ins and Outs of the Outbox Pattern"

An invaluable pattern to ensure a service can update its own database and send messages to other services via Kafka, consistently. In this talk I'm discussing implementation options, backfills, alternatives, etc.

Told my husband that working with ChatGPT is like working with a semi-invested intern who’s never going to think about you or your business again when their internship ends.

"Help! My LocalDate Isn’t Flattened"

Enjoyed reading this post by @horstmann.com about the subtleties of turning Java's LocalDate into a value type for Project Valhalla. Null-ability and built-in object serialization keep haunting us.

The Ashes - known to me as my biennial attempt to pass myself off as a cricket fan - gets underway this week.

There's something really very wonderful about 5 day, unlimited over test cricket that, for me at least, cannot be reproduced in T20, ODIs or any other audience friendly format.

Corrosion Corrosion is distributed service discovery based on Rust, SQLite, and CRDTs.

Reading about Corrosion: a Rust project that replicates a SQLite database using a gossip protocol. Really cool intersection of SQLite, CRDTs and SWIM. I also appreciate how openly they document their gnarlier failure modes and war stories so far fly.io/blog/corrosi...
