I liked the simplicity and uniformity of that setup, but decided it’s time to add at least one fiber connection, to get rid of a…

I'm a software and network engineer living on the west coast. I currently work at Qumulo writing a petabyte-scale CDN with linearizable reads and writes at every edge. Previously, I worked at Arista Networks doing network automation, large scale digital-twin network validation, and routing for SMPTE2110 networks.
FM radio headphones were given out at the door. Each set was tuned beforehand to receive a broadcast from my programmed station. Visitors were then invited to walk around the room, contemplating the artifacts of the exhibit.

tl;dr: I successfully got the Intel I340-T4 4x Gigabit NIC working on the Raspberry Pi Compute Module 4, and combining all the interfaces (including the internal Pi interface), I could get up to 3.06 Gbps maximum sustained throughput. Update: I was able to boost things a bit to get 4.15 Gbps! Check out my video here…

Twitter tried to reduce load times for external links, but made things slower instead. It mistakenly normalizes domains to a point where they’re no longer useful.
Just over a year ago, we founded Tailscale with a common sense of nostalgia for the “good old days” of LANs. In our collective opinion (then and now) networking and cloud infrastructure has become too complicated. Attempts to increase team connectivity and migrate towards remote work results in a corresponding burden…
Circles is a surveillance firm that reportedly exploits weaknesses in the global mobile phone system to snoop on calls, texts, and the location of phones around the globe, and is affiliated with NSO Group, which develops the oft-abused Pegasus spyware. Using Internet scanning, we found a unique signature associated…
More portable, fully wireless smart home setups. Lower power wearables. Batteryless smart devices. These could all be made possible thanks to a new ultra-low power WiFi radio developed by UC San Diego engineers. It enables WiFi communication at 5,000 times less power than commercial WiFi radios.
After over 20 years of DNS and PowerDNS, I am moving on. Separate from this page, I am releasing a series of three huge posts on the history of PowerDNS.
