Effective Concurrency with Algebraic Effects in Multicore OCaml

Best Practices – Why I Hate Them
I hate the expression “best practice”, it’s so, so often used by someone to justify the application of cargo cult without actually understanding why.

And you will know us by the company we keep
It feels as if we're at the tail end of the first era of social media in the West. Looking back at the companies that have survived, certain application architectural choices are ubiquitous. By now, we're all familiar with the infinite vertical scrolling feed of content units, the likes, the follows, the comments, the…

When can glibc be built with Clang?
Updated in 2026: glibc 2.43 added experimental support for building with Clang. In September 2021, I wrote "So, dear glibc, will you be happy with my sending Clang patches?" in Build glibc with LLD 13. We have come to a turning point. In Linux Plumbers Conference 2021, at the glibc Birds of a Feather session, I asked…

Pro rata is a bad term for founders
For a long time, I was a strong believer in investor pro ratas. As a founder, I understood the trade and was comfortable with it. As a partner at YC, I thought it made enough sense that I helped...

European Parliament Voted to Ban Remote Biometric Surveillance
It’s not actually banned in the EU yet—the legislative process is much more complicated than that—but it’s a step: a total ban on biometric mass surveillance. To respect “privacy and human dignity,” MEPs said that EU lawmakers should pass a permanent ban on the automated recognition of individuals in public spaces…

So You Want to Rust the Linux Kernel?

SRE Doesn’t Scale
We encounter a lot of organizations talking about or attempting to implement SRE as part of our consulting at Real Kinetic. We’ve even discussed and debated ourselves, ad nauseam, how we can apply it at our own product company, Witful. There’s a brief, unassuming section in the SRE book tucked away towards the tail…

Worst Case
Suppose you’re running your organization’s crucial apps in the cloud. Specifically, suppose you’re running them them on AWS, and in particular in the “us-east-1” region? Could us-east-1 go away? What might you do about it? Let’s catastrophize!

Sending Emails to Myself
In April, I wrote operatornotify.py , a module which allows my programs to notify me of important information or errors. I was immediately very proud of it.

3D Printing Sex Toys
Ok so, sex toys! Admit it. You've thought about it. 😉But it seems so complex! You can't use a sex toy straight from the printer because the materials and nozzles aren't body safe, and even if they were, the layer lines are a breeding ground for bacteria. So traditionally you'd have to print a blank and smooth it (with…

How the biggest consumer apps got their first 1k users
Considering every startup confronts this question at some point, I was surprised by how little has been written about it. Particularly anything actionable. So I decided to do my own digging. I spent the past month personally reaching out to founders, scouring interviews, and tapping the Twitterverse. Below, you’ll…
