We have recently introduced Oxy, our Rust-based framework for proxies powering many Cloudflare services and products. This is how it spans various layers of the OSI model, by handling directly raw IP packets, TCP connections and UDP payloads. cfl.re/3lOhfbJ

Finally got the all clear from the orthopedic dr to resume punishment. Just in time for the mercury to go above 50 (and the wind speed to go below)

And the hits keep coming - pretty soon there won't be a single part of my day-to-day that isn't covered by a Cloudflare blog😃

Finally finished Jedi: Survivor. IMO, exceptional game. Combat, story, graphics/sound design all greatly improve on fallen order. Will continue to replay

"The day my ping took countermeasures" Join me for a deep dive into Linux ping utility! From NTP drift, via digging through 1983 code base, through VDSO, LD_PRELOAD, ping sockets API, barely known strace fault injection, up to ICMP packet mangling.

[New Post] Linux Sockets and Relevant Syscalls oswalt.dev/2025/07/linux-…

📢[NEW POST]📢Today I explore Unix Domain Sockets - these are sometimes an overlooked capability for inter-service communication with some really unique features, and will be the foundation for blog posts I aim to write in the near future. Enjoy! 😄 oswalt.dev/2025/08/unix-d…

📢📰 NEW POST! 📰📢 I explored building a neural network in Python in order to really build an intuitive understanding of how it all works. I found it super fun, and even included an interactive notebook at the end you can play with on your own. Enjoy! oswalt.dev/2025/08/a-simp…
