Closing #systemsdistributed: "Mission-Critical" by @joran.tigerbeetle.com.

Around the world this week, TigerBeetle and friends in Munich, Lisbon and Rio! With Georg currently leading the Olympics...

Last year at #systemsdistributed, @joran.tigerbeetle.com showed the power of an interface for performance.

Join us for the 4th TigerHoops at MIT's main court! Wednesday, July 29 from 17:00 until 19:00. luma.com/h97y9glw

For years, asynchronous I/O on Linux was a promise the kernel couldn't keep—until io_uring. We're grateful for @axboe.bsky.social's contribution to systems programming, and excited for this origin story at #systemsdistributed. (Right after Jonas Axboe races Radical Cup, Atlanta!)

The future deserves good architecture! As code becomes commoditized, systems design experience and architectural wisdom should strengthen, not fade. At #systemsdistributed, @jamescowling.dev on innovation without sacrificing quality. In Boston, home of Viewstamped Replication.

The Bi-Channel Networking Paradigm for Database Systems in the Cloud cs.cit.tum.de/fileadmin/w0... Congratulations to the authors, Georg Kreuzmayr, Muhammad El-Hindi, Tobias Ziegler, Benjamin Wagner, and Viktor Leis! Also for its acceptance at EDBT 2027.

Lightning Talks are a highlight at Systems Distributed! Submissions are taken on Day 1, selection is entirely the choice of our moderator—for four years running, @nvais.bsky.social of Spark Capital—and on Day 2, the chosen speakers take the stage! Last year's: www.youtube.com/watch?v=k58v...

Excited to share that @zooko.bsky.social will speak at #systemsdistributed!

From Bell Labs to NASA's Jet Propulsion Laboratory, Margaret Holzmann spent three decades designing mission-critical systems, including autonomous spacecraft planning software. At #systemsdistributed, cosmic lessons in systems thinking.

Jonas Axboe finished pole in 2 of 3 races for Round 3 of the Radical Cup North America, at Road America, ending the weekend with 391 points and extending his lead as the Pro 1500 class champion!

Ruby, Ruby, Ruby! www.youtube.com/watch?v=63G0...

Ram Alagappan argues the core abstraction behind modern streaming systems should become forkable. At #systemsdistributed, he'll present AgileLog, a forkable shared-log abstraction with novel primitives, and how to implement it.

TigerBeetle 0.17.8 is released! - Publish Ruby client. - Fix stash overflow crash. - Improve performance for clusters with many clients. github.com/tigerbeetle/...

A year since #systemsdistributed '25, almost time to gather again!

In 2016, Heidi Howard showed that Paxos’ quorum requirements were in fact over-specified, by introducing Flexible Paxos. Join us at #systemsdistributed to celebrate the 10th anniversary of Flexible Paxos! @heidihoward.bsky.social

What remains when agents start writing and humans stop reading code? Next month, Dominik Tornow at #systemsdistributed! @dominiktornow.bsky.social

Datacenters are breaking the server apart, in turn breaking assumptions about fault tolerance, latency, and coherence. At #systemsdistributed, Aishwarya Ganesan, co-author of Protocol-Aware Recovery, on the challenges of disaggregation and two systems built to solve them.

May in TigerLand is out! - Linux loop reworked; 8% throughput increase! - Swival audits TigerBeetle (merci, Frank). - An elephant squeezed from both sides... tigerbeetle.com/newsletters/...

NASA's Power of Ten Rules for Safety-Critical Code by Gerard Holzmann—static allocation, assertions and explicit limits—changed the way we code; They're intrinsic to TigerStyle. And now it's our joy to present The Power of Ten, live! At #systemsdistributed with Gerard Holzmann.

Next up... "Logic isn't just for detectives and mathematicians! A small bit of logic helps us programmers in all sorts of ways, from testing better to actually making sense of left outer joins." @hillelwayne.com returns to #systemsdistributed to teach Logic for Programmers!

TigerBeetle 0.17.7 is released! - Refactor and fuzz the REPL parser. - Ensure race-free CI release validation. - Replace Hatchling with a zig-only wheel builder for reproducible python client builds. github.com/tigerbeetle/...

Opening Systems Distributed '26: Andrew Kelley's State of the Tagged Union Address! Find out what's cooking in Zig land: recent major advancements, demos of what's close to finishing, and roadmap for the next several years. #systemsdistributed @ziglang.bsky.social

the slickest upgrade path I've ever seen is @tigerbeetle.com's, where you provide the new binary on every node and once the cluster knows all nodes are equipped they all instantly restart and recover as quickly as possible

Straddle.com's system of record used to depend on external sources of truth: bank statements, delayed responses, and inferred state. Now, they own it. An in-house financial system of record that's fast and correct, powered by TigerBeetle. tigerbeetle.com/stories/stra...

The full house of speakers for Systems Distributed '26: Andrew Kelley @axboe.bsky.social Gerard Holzmann @jamescowling.dev @heidihoward.bsky.social Ram Alagappan Aishwarya Ganesan @zooko.bsky.social @hillelwayne.com Margaret Holzmann @dominiktornow.bsky.social @joran.tigerbeetle.com

"TigerBeetle provided the flexibility and foundation that allowed us to build specifically around our operational and scalability requirements. With TigerBeetle, OKTO PAYMENTS can continue to scale without revisiting its foundation." – Kalebi Serafim, CTO

TigerBeetle mentionned!

"At this point it's a platitude but I'll say it anyway: Building distributed systems—that is systems with multiple interacting nodes—is notoriously hard to get right." –Chaitanya Bhandari on protocol-aware deterministic simulation testing, Bug Bash 2026 www.youtube.com/watch?v=F78F...

Surprised I haven't seen @tigerbeetle.com more before today. Really great presentation www.youtube.com/watch?v=yKgf...

The OLTP, OLGP, OLAP spectrum: "Postgres is in the middle as a general-purpose system and there are hardcore OLTP systems out there, like TigerBeetle. TigerBeetle can run so many circles around Postgres in transactions it's insane." – @hannes.muehleisen.org, @duckdb.org

April in TigerLand is out! - Switching to star replication, taming P100 latencies - TigerBeetle goes on tour to BugBash '26 - TigerHoops in the Bay area! tigerbeetle.com/newsletters/...

New blog post, out tomorrow! Building a Rust Client for TigerBeetle, part II...

TigerBeetle 0.17.4 is released! On Linux, you'll need to be on kernel 5.11+. - Simplify and speed up the event loop with ~8% throughput bump. - Add metrics for object cache usage. - Warn if event loop ticks take too long. github.com/tigerbeetle/...

"The best software is more than a program, it's a relationship between the makers and the users. And so, Systems Distributed is: How can we get back to crafting more quality software."

TigerBeetle 0.17.3 is released! - Replace adaptive replication with star, taming cross-region p100. - Guard against GitHub actions supply-chain attacks using SHA pinning. - Simplify Zig-Zag merge control flow with galloping search. github.com/tigerbeetle/...
