Whether or not you use AI to code, you need Antithesis to make sure it works in the situations you *didn't* think of.
@Shark_Academia this is one of the reasons why we're super bullish on @AntithesisHQ as a way to build confidence in the code so we can move faster

David MacIver is the primary author of the world's most widely used property-based testing tool, the #Hypothesis library for #Python. On this episode of the #BugBash podcast, he chats with @akshayshah and Will Wilson about shrinking, context windows, and making testing tools

We popped a cassette into the VCR to record Will's interview with @tbpn on Monday. Link to the full segment below.

One of our company goals is making this whole process stupid simple for most people and companies, but there will always be a way for the hard core to eke out more performance, and Pierre's post is a great way to structure your thinking on how to do it.

Nice post from the great @PierreZ on how to write generative testing workloads that actually find bugs:

Customers often ask us how they should be testing, since this isn't the kind of thing that's taught in school (though it really should be!), so we just published our first testing tactics guide. This one documents a simple test workload we call the “ring test.” It can be used

If you're looking for space to host a highly technical engineering talk/meetup in the bay area, we have room and love visitors. Drop us a line! But really - technical topics/groups only please.

How're real estate prices in SF, you ask? Well, yesterday we raised a $105M Series A, AND we opened an SF office... coincidence? You decide. Thanks @entersudonym and the SF Systems Club for inaugurating our new space with a high energy, standing-room-only event!

How better to celebrate a fundraise than with a 90 minute talk about hypervisor architecture?
Final SF Systems Meetup is a go! So excited to hear Alex from @AntithesisHQ dive deep into their deterministic hypervisor!

A simple thesis - AI is going to be writing dramatically more code in the future. - We'll need substantially better testing infrastructure to trust it. - Antithesis are the best in the business. Proud to be a backer!
A new blog post about how we've adopted Antithesis as part of our testing story. This is kind of a new thing for us, because we liked Antithesis (both the people and the product) well enough that we're now leading their next funding round.

Polymathic, but his short attention span means we don't let him have an account on X.
Jane Street can speak to the technical innovation behind Antithesis much better than I could, but the reason I'm long (literally) is that Will Wilson (the CEO) is one of the most polymathic and interesting people I've ever met.
