Security concerns with the e-Tugra certificate authority
Certificate authorities (CAs) are a critical backbone of internet security; when they are compromised, users lose the ability to securely connect to websites without fear of interception. Websites cannot insulate themselves against a fully-compromised CA, even if they normally use other CAs.

The new .zip TLD is going to cause some problems
Many years ago, Google applied for the .zip Top Level Domain. ICANN, in its infinite wisdom, granted it. And now, I think, bad things are going to happen. You see computers try to be helpful. They see you wrote "visit example.com" and autolink the thing which looks like a domain name. That's handy - especially as most…

What happens when DNS in China is poisoned and pointed at your server
I’ve been using the Internet in one form or another since the mid-80’s. In that time, I’ve seen a lot of strange stuff happening on our global network. On Tuesday, I experienced something extraordinary. It all started with a text message from my partner Ged at 8:30 AM: Mail server down. Please take a look […]

Recently, I had an opportunity to build a WireGuard jail on a FreeBSD 12.1 host. As it was really quick and easy to setup and it has been working completely fine for a month, I’d like to share my experience with anyone interested in this topic. I would like to use WireGuard app on my Android phone to access my home…

Exploring a Modern SMTPE 2110 Broadcast Truck
In October, my Dad and I got to go behind the scenes at two St. Louis Blues (NHL hockey) games, and observe the massive team effort involved in putting together a modern digital sports broadcast. I wanted to explore the timing and digital side of a modern SMPTE 2110 mobile unit, and my Dad has been involved in studio…

Graviton 3, Apple M2 and Qualcomm 8cx 3rd gen: a URL parsing benchmark
Whenever you enter a URL into a system, it must be parsed and validated. It is a surprisingly challenging task: it may require hundreds of nanoseconds and possibly over a thousand cycles to parse a typical URL. We can use URL parsing as a reasonable benchmark of a system performance. Of course, no single measure ……

Cloud Traffic
I recently watched Build an enterprise-grade service mesh with Traffic Director , featuring Stewart Reichling and Kelsey Hightower of GCP, and of course Google Cloud’s Traffic Director . Coming at this with a brain steeped in 5½ years of AWS technology and culture was surprising in ways that seem worth sharing.

Some interesting stuff I found on IX LANs

Creating a Home IPv6 Network
One of the recent experiences of Linux Plumbers Conference convinced me that if you want to be part of a true open source WebRTC based peer to peer audio/video interaction, you need an internet address that’s not behind a NAT. In reality, the protocol still works as long as you can contact a stun server to tell you…
