Ripgrep is faster than {grep, ag, Git grep, ucg, pt, sift}
In this article I will introduce a new command line search tool, ripgrep, that combines the usability of The Silver Searcher (an ack clone) with the raw performance of GNU grep. ripgrep is fast, cross platform (with binaries available for Linux, Mac and Windows) and written in Rust. ripgrep is available on Github. We will […]
Box of Secrets: Discreetly modding an apartment intercom with Matter
My friend Frank (not his real name) hosts a lot of guests at his apartment, and his complex’s intercom is what ushers them inside. You’ve probably seen them before, they look like this: The Doorking 1834-080 intercom at Frank’s apartment. Up until recently, guests could find Frank’s number in the system and give it a […]
Epoch confirms GPT5.4 Pro solved a Frontier Math Open Problem for the first time
Solution Update: This problem has been solved! A solution was first elicited by Kevin Barreto and Liam Price, using GPT-5.4 Pro. This solution was confirmed by problem contributor Will Brian, and will be written up for publication. A full transcript of the original conversation with GPT-5.4 Pro can be found here and GPT-5.4 Pro’s write-up […]
I Created My First AI-Assisted Pull Request and I Feel Like a Fraud
I created my first AI pull request for Chroma, which is the default syntax highlighter used in Hugo. I used Claude Code for that PR. I didn’t learn anything. I felt like I was flinging slop over the wall to an open-source maintainer. I felt like a fraud and my impostor syndrome got worse. But […]

Cloudflare’s Gen 13 servers: trading cache for cores for 2x performance
Two years ago, Cloudflare deployed our 12th Generation server fleet, based on AMD EPYC™ Genoa-X processors with their massive 3D V-Cache. That cache-heavy architecture was a perfect match for our request handling layer, FL1 at the time. But as we evaluated next-generation hardware, we faced a dilemma — the CPUs offering the biggest throughput gains […]
The Resolv hack: How one compromised key printed $23M
On March 22, 2026, the Resolv DeFi protocol became the latest example of how quickly things can unravel in DeFi when security assumptions fail. In a matter of minutes, an attacker was able to mint tens of millions of Resolv’s unbacked stablecoins (USR) and extract roughly $23 million in value, triggering a sharp de-peg and […]
Hacker Mints $80M USD Worth of USR Stablecoins
A hacker has exploited Resolv Labs’ smart contract, where it was able to mint at least $80 million worth of USR stablecoins. As a result of the hack, USR crashed to $0.025, i.e., 2.5 cents, within hours. The stablecoin is unlikely to emerge after an 80% de-peg similar to Terra Luna’s UST. However, the hacker […]

Whistler: Live eBPF Programming from the Common Lisp REPL
A string of recent experiments around observability and security for agentic AI systems led me down the eBPF rabbit-hole. When I emerged, I came back with a full optimizing compiler for a Common Lisp-based DSL for eBPF called Whistler. Whistler lets you write shorter code, with less ceremony than eBPF C code, and still produce […]
