IronBeetle⚡️ Ep. 093 Benchmarking Harness youtu.be/ho403jvfKOY

"My schtick as a software engineer is establishing automated processes — mechanically enforced patterns of behavior. I have collected a Santa Claus bag of specific tricks I’ve learned from different people, and want to share them in turn." — matklad matklad.github.io/2025/12/06/m...

The write last, read first rule // @dominiktornow.bsky.social - @tigerbeetle.com You should write an agent // @sockpuppet.org - @fly.io Indexing sparse vectors with Turso // Nikita Sivukhin - @tur.so

TigerHoops NYC, thanks for coming out. Next up, San Diego! luma.com/ut8b31x1

November in TigerLand is out! - A lot of code refactoring! - The Write Last, Read First Rule, by @dominiktornow.bsky.social - An accidental lecture on the mathematics of consensus, by matklad with Tobi mailchi.mp/tigerbeetle/...

 Does the world need an OLTP-only DBMS? "What is the difference between building on top of a general purpose database?" - @aaronfrancis.com "The problem is the locks that general purpose is going to hold across the network round trip..." - @joran.tigerbeetle.com

IronBeetle⚡️ Ep. 092 Went just as you might have guessed! Looks like we'll need three more episodes to tackle that while... youtu.be/9DJxUTm1uAY

Elixir + Zig + TigerBeetle = ⚡ Find out why at TigerBeetle 1000x World Tour in Milan this December 6th.

Join Matklad and me in Lisbon next week for an evening of systems engineering with @tigerbeetle.com and @resonatehqio.bsky.social I will talk about Write Last, Read First: How to keep systems consistent without transactions bsky.app/profile/tige...

Mathematics of Consensus — Accidental Lecture with matklad and Tobi Full lecture: www.youtube.com/watch?v=thY1...

"If you can't count correctly with contention at high speed, it's not OLTP. And if you're not doing serializable, if you're cutting corners on isolation, it's not ACID." Full talk: youtu.be/yKgfk8lTQuE

Great interview about @tigerbeetle.com, a custom-built database for financial transactions. Don't watch it if you actually have stuff to do :D www.youtube.com/watch?v=9oyh...

Excited to see many of you on tour in less than 2 weeks. The talks, from TigerBeetle engineers and friends, will range from multiversion binaries and toolchain decisions to consensus and 1000x performance. 13 cities, 1-6 December—we can't wait! luma.com/calendar/cal...

IronBeetle⚡️ Ep. 091 Zig Zag Merge (in Zig, of course ⚡️) youtu.be/NyMRZxcw0Ek

BRB, going to implement cluster time. 😎 #tigerbeetle brilliance is like on every post they do. I learn so much just from reading their posts. Let alone going over there code. This is what resilient db looks like.

"Remarkably, if the system of record provides strict serializability, like TigerBeetle, and if ordering is correctly applied, then the system as a whole preserves strict serializability, leading to a delightful developer experience." tigerbeetle.com/blog/2025-11...
