Make Britain rich again
The UK is a great country with an extraordinary history. Our stagnation is real, but it's fixable and worth fixing. Enjoyed giving this talk at @lfg_uk last week and so encouraged by the optimistic responses I've had from people who are building a brilliant future for Britain 🚀

The last member of the pre-acquisition Firebase team has left the building
Today is my last day at Firebase. 4,211 days where I lived the dream: join a small startup, build cool stuff, and grow to insane scale. All while meeting the greatest people. It's been amazing and I'm excited for what's next.

My favorite feature of Tasklet is you get your own virtual computer that its agent can run on. And you can watch it in realtime. And it’s really good. Go try this!
Today we're launching Tasklet — an AI agent for automating your business. Unlike ChatGPT, @TaskletAI actually does the work for you: connecting to your tools, triggering automatically, and handling tasks while you sleep.

We had too much fun with this launch sequence 🤣 Super excited to share some footage of our injection operations for the first time! This storage capacity is a huge step forward for Charm, and shows a repeatable regulatory precedent for taking orphaned oil and gas wells sitting

After a long time away, I just put twitter/X back on my phone. Who do you find the most insightful and enjoyable here? DevTools, AI, and Consciousness/Meditation are my jam.

😅 If this doesn't work out, I'll fall back to being a voice actor.
Yeah, an eval platform that lets models collaborate or compete in a variety of real-world scenarios is cool and all, but have you heard @JamesTamplin's soothing voiceover?

How well do GPT-5 and Opus 4.1 vibe-code apps? We wanted to find out, so we asked them both to build a full-stack chiptunes app on @instant_db! Here's what they got, and what we learned:

To have this little security you would have to actually fight the default platform behavior. By default Firebase buckets are "locked." You'd have to very intentionally set it to public. And it will scream at you and warn endlessly when you try to do so.

AI products fail constantly—in ways both hilarious and terrifying. Regular software throws exceptions. But AI products fail silently. Meet @raindrop_ai : the first Sentry-like monitoring platform for AI products.

Just figured out where these fake tariff rates come from. They didn't actually calculate tariff rates + non-tariff barriers, as they say they did. Instead, for every country, they just took our trade deficit with that country and divided it by the country's exports to us. So we
It's also important to understand that the tariff rates that foreign countries are supposedly charging us are just made-up numbers. South Korea, with which we have a trade agreement, is not charging a 50% tariff on U.S. exports. Nor is the EU charging a 39% tariff.

I've been hacking on a project lately with one of the other early Firebasers. We spend a comical amount of time figuring out how Firebase/Google Cloud works now.

I'm observing that my critical thinking is degrading when coding with AI. I'm just throwing the errors at Claude and expecting it/he/they to fix them.
