Compelling session today by Marek Siarkowicz using Antithesis deterministic simulation to help improve #etcd robustness.

Today our CEO, Will Wilson, announced a partnership with
@cncf.bsky.social to provide free reliability testing for Graduated and Incubating projects. Stop by booth 457 to learn more!

Hullo #Kubecon! Drop by and see us at booth 457 and enter our raffle to win this out-of-print NES Lego set!

Perfect for filling the hours when you're waiting for your handwritten integration tests to run.

And if you're in the EU, come see us at #WebsummitLisbon (Booth 0402-48)! Max Jacobson is giving a keynote on the Developer Stage on Tuesday, and we'll have some awesome new continent-appropriate swag, perfect for the next football match where you just want both teams to deliver bug free software.
November 10, 2025 at 4:44 PM
Hullo #Kubecon! We'll be at booth 457, talking about Nintendo games and the great work the @etcd team did with Antithesis this year. We'll have a few surprises we're keeping mum about for now, but we're proud to wear our love for open source distributed systems infrastructure on our sleeve!

Gonna keep the boring corporate announcement short.

Antithesis now allows you to orchestrate with the same Helm chart you use in production. #kubernetes!

Until a few weeks ago, you could only use docker-compose. It seems slightly silly to say, but it's true.

#Current25 NOLA by @confluent.io is kicking off right now! (Or maybe the party's still going from the night before.)

Come see us at Booth 302 - if you don't know what you'd like on your arm, here are some suggestions from our tattoo artist extraordinaire!
October 29, 2025 at 1:35 PM
If you've never gotten tattooed at a tech conference, you should come see us and at #Current25 in NOLA tomorrow and Thursday!

We THINK they're temporary.

If you read one thing today, make it this blog post by our friends @fly.io. This is what tech writing should be like: witty, relatable, informative. Corrosion is a remarkable system, and we aren't just saying that because it was #TestedwithAntithesis.

❤️ y'all!

We know what you sickos want is a deep dive into the mathematical model used to determine if a bug has been fixed. Here it is (link in first comment).

New mascot day! Here's @akshayshah.org introducing our new mascot to a packed audience at @leaddev.com NYC. We're very sorry about what happened to the old mascot.
October 15, 2025 at 9:00 PM
New York friends & reliability nerds! We'll be at #LeadDevNewYork and #StaffPlusNewYork this week, hosted by @leaddev.com

Akshay Shah will be trotting out our new unofficial mascot, come say hi!

Come for the database poetry, stay for the pineapple shirt. Or is it the other way round?

Kyle Kingsbury was on our podcast a few weeks ago with some hot takes on databases -- because what else are you gonna do on the weekend if not listen to a podcast about how databases break?

Full ep below.

This is kicking off in 45 minutes! Take the vibes out of your engineering - LLMs might be non-deterministic, but that doesn't mean you have to let them introduce uncertainty into your code.
⏰ TOMORROW! ⏰ Join experts from @antithesis.com to learn how to move beyond AI-code generation's "partial wins" to achieve true engineering productivity. It's time to rethink your workflows and tooling to integrate AI seamlessly.

Vibe-engineering anyone?

Simon Willison, @simonwillison.net here, just coined the term “vibe-engineering” – using LLMs to help write production code.

"On average, each property-based test finds about 50 times as many [bugs] as the average unit test."

It's podcast day!

@joran.tigerbeetle.com is one of the very few people/companies out there who might be more fanatical about reliability than we are, and he's built @tigerbeetle.com accordingly.

Data streaming platforms are the jet engines of the internet. They make the whole thing go, they make the whole thing fast, and the reliability and correctness requirements are virtually in a class of their own.

Hello San Francisco! We're at the Data Streaming Summit #DSS today and tomorrow with StreamNative and a who's who of the data streaming industry.

Lawrie and Connor take the stage at 3:45 tomorrow, here's Lawrie at BugBash, on the power of randomness in testing. Full video in the comments.
