Dropping eBPF CPU Cost by About 90% with Memoization (Not AI Gen)

My brother and I spent a lot of time designing our eBPF security agent to be really fast from the ground up, but recently we discovered we could make it much faster using memoization! A couple of weeks ago, I profiled the eBPF code and found that the most expensive part of the protection isn’t actually enforcing a policy (allow/deny), but figuring out which policy applies to a given file open. ,My brother and I spent a lot of time designing our eBPF security agent to be really fast from the ground up, but recently we discovered we could make it much faster using memoization!

Charts built for Chat

We're open sourcing dbt Charts, a declarative language for dashboards, so that even the dashboards you build by chatting with an agent can be governed.

Optimizing a Spin-Lock

A spin-lock is a lock that never sleeps. Instead of yielding to the scheduler, the thread stays on the CPU and spins. No syscalls. No context switches. In this …

The biggest dinosaurs couldn't sit on their eggs

Fossil eggshells believed to be from some of the biggest dinosaurs that ever lived have been found in a surprisingly cool climate far from the equator. But those titanosaurs were too big to sit on their eggs. Microscopic evidence shows what they did instead to keep the eggs warm enough to hatch.

How my e-reader lost its stripes

I’ve been a lifelong reader, which has proved a fragile habit in our era of endless trivial distraction. While books and e-ink readers solve the problem of competition for attention, they can’t compete with a phone for convenience. That tiny device in my pocket has made reading both easier and more vulnerable to displacement whenever a notification pops up. A few days ago, I learned for the first time about a recent generation of tiny e-ink readers. Since they’re cheap, it was easy to give into curiosity: I bought an Xteink X3. Not only is it astonishingly tiny, I could immediately install the delightful open-source CrossPoint firmware. I was very quickly able to install a few books. I also appreciated being able to install custom fonts, th

Why don't machine learning research agents overfit?

New research shows that AI agents — like human research communities — learn strategies compressible enough to fit in a few tokens, which prevents memorization and explains why benchmark-driven ML keeps producing real progress.
