Modern software tooling is amazing. I can go from zero to working thing that I don't understand at all and have zero chance of debugging in a timely fashion quicker than you can say "thank god I don't have to support this thing".

Years ago, I ran a team where I had us invest in making sure we could quickly and safely roll back any release and then, I forbade anyone from using it with the mantra "always forward. never back." I wanted us to go through the process of getting our releases rock solid and easy to undo, I didn't actually want us solving problems by going backwards.

The breakthrough that let us crush Dragon's Lair and Starcraft also makes it *much* easier to set up Antithesis. So we're launching a simpler offering for startups and small teams. DM us for early access, brutal honesty required.

Sometimes there's a huge performance optimization staring at you and you just don't see it- until you do.

Programmers on Twitter. Too many of y'all are way too literal. Ya need to joke to slap ya in the face I guess.

The number of "AI is bad" posts on LinkedIn that sound like Claude is pretty hilarious.

Based on the bugs I encounter all the time with Claude Code, I'm not sure I want a code review tool from the folks at Anthropic.

man the "pre-existing fake" brush off seemed to be trained down into the soul of every model that i have used.

I'm in an @AntithesisHQ internal meeting about the guts of "hard tech" part of the product. We do these periodically as "learn more about it". I join each one because each time I learn at least 1 or 2 new things. But, the thing I am reminded of every time. Pulling off the hard-tech part is doable for anyone- especially now with agents but... And this is a big but (Sir Mix-a-lot would love it).. Making it all actually useful is the result of tons and tons really hard learned lessons. I need to remind myself of that with all my "I can have an agent just..." Because that "just" is hiding a ton of domain expertise. And a lot of that domain expertise isn't in anyone's training data.

I have so many LLVM builds going on in GitHub Actions. I apologize if the site crashes soon.

You know what they say about overnight sensations.
Yes I swear we were totally invented in 2026 😅

Years ago, I worked out live during a podcast that my idea of beautiful code was code that didn't wake anyone up at 2 am. And unsurprisingly, I ended up at @AntithesisHQ because I have long been obsessed with software correctness and not letting problems get out into production.

Reducing pain is great. Preventing it is better. Ask me about the migraine I had that lasted 5 years.

Time-Traveling Agents! antithesis.com/blog/2026/tim… The Antithesis Multiverse Debugger is now available via API and CLI :-)
What if saying `claude build me a cloud platform make no mistakes` actually worked??? With the newest Antithesis release we have closed the loop and enabled agents to ship reliable systems: antithesis.com/blog/2026/tim…

Once upon a time in the time of the olds, there were these people called "punk rockers" and they all had very distinct and individual sense of style that slowly converged on a uniform but the uniform was coopted by marketers and so these folks changed "who they were" in respond to external feedback. To my mind, such reactions are the least punk rock thing ever. To me, "punk rock" was about doing our own thing. It was about Black Flag members growing out there hair because that is what they wanted and if it pissed off their uniform wearing fans well, ok, that is kind of fun. I think about this phenomena a lot as I watch some folks obsess over making sure their writing doesn't "sound like AI" and even in some cases changing how they write. I've done that a couple times- changed how I would write something because of "that sounds like AI". And I felt ashamed. What a stupid stupid stupid thing to do. Fuck em I see. Fuck em.
