New layout for my blog, built mostly by @magicpatterns 😎
Best AI layout generator I've tried so far by a wide margin

Did some reading on formal verification this weekend:
hashcloak.com/blog/tutorial-…
vitalik.eth.limo/general/202…
adam.math.hhu.de/#/g/leanpro…
Absolutely worth reading. Especially vitalik's post if you want spark notes version. FV is hot these days, and it's not just empty hype.
Even sequoia is making cuts - massive bearish indicator
uhh so this is how i found out that i'm not only no longer a Sequoia Scout, my main partner (and boardmember since @Temporalio) is also gone.
no email from sequoia yet about anything in the past month. no response to my texts from any partner.
I literally left my previous partnership to join Sequoia because I respected what they have built and thought they represent the epitomy of what being long term partners could be in Silicon Valley and I wanted to be closer to that from the inside rather than read about it in @colossusmag hagiographies.
disappointed. i respect the new direction but the collateral damage is high.
on the plus side, i think i am done being a scout. @mariadlzollo and I are going to raise a small side fund, by founders for founders. we are seeking a compute partner (possible GP, or just sponsor/in-kind-investor), and a researcher GP.
pls enquire within - dm or text if you have me, else business@latent.space

The coolest part of this video is that it was generated entirely using puppeteer and 300 lines of JS 😎

New on mongoosejs.com: our guide to using indexes with Mongoose in production
Includes our guidance on:
1. When to index vs when not to
2. When to use autoIndex vs createIndexes vs syncIndexes
3. Path-level vs Schema.prototype.index

In post LLM world, security is way more important than features or UI
Any competent dev with a Claude subscription can probe your entire public API for weaknesses in minutes. Would've taken hours in 2021
Security incidents across open-source aren't showing signs of slowing down
The Bun team is dedicating a higher % of our time to security work for the foreseeable future

Mongoose Studio helps you work better with your agents.
Instead of giving Claude full write capabilities, you can tell it to write sandboxed scripts that you can review, edit, and run manually.
Moved one client off of Vercel environment variables. Going back to my roots of storing encrypted secrets in MongoDB directly.
Vercel just stores one encrypted env var: config URI to load from, and that URI has a strict IP whitelist
It has been a day.
I think I'm finally done with allowing my team to use environment variables for credentials.

The big difference is that if you have an edge case or UI tweak for airtable and you're paying them only $500/mo, airtable will ignore you. At best you'll get some offshore support tell you they'll get to it Q2 2028
Remember the 2nd S in SaaS is for "service"
4 months ago I cloned Airtable for a client in 5 days because they refused to pay Airtable $500/mo
months later, I’m still maintaining it
every two weeks it’s another edge case, a UI tweak, or a "quick 10-minute request." They’ve easily spent 10x more in headaches than the $2,000 they would’ve paid Airtable
just proving that SaaS isn't dead. Cloning isn't enough, if you want it to be same quality as original it becomes a full time job
and at this point isn't it easier to just pay?

Speaker submissions are officially open for Replay 2027!
Replay, our annual conference, is coming back to San Francisco May 17-19, 2027. We'd love to invite you to share hard-earned wisdom from putting the next generation of software into production.

Sad to see the end of BioWare - a lot of fond memories playing KotoR and ME. The TOR and ME2/3 soundtracks are still focus session staples.
So today, let's remember Mass Effect's central theme: together, we can accomplish what no one could achieve alone

Working on new docs for @mongoosejs 👇
Existing Mongoose docs overemphasize the API reference section, which were the most viewed pages pre LLMs.
Now we're spending less effort on API docs and more on guidance and recommendations.
Adding a new guide about using indexes in production to mongoosejs.com
Covers:
- When to add indexes and when not to
- autoIndex in production
- syncIndexes in production
And a whole lot more.
Take a look and let us know what you think: github.com/Automattic/mongoo…

Getting some good use out of that Mongoose Studio Vercel MCP integration
The script UI also comes with a Dry Run mode for added confidence - run the whole script in a transaction then abort.
Secure MCP access to production with final user review for scripts that modify data. Directly from your agent.😎

Huge! Maybe worth taking another look at Bun
We’re likely going to do this because schema validation libraries are basically the worst case scenario for AOT performance without compiler integration

if you've enjoyed ArkType, Standard Schema or my TypeScript perf work, a repost would mean a ton 🙏
