Achieving 100 Gbps intrusion prevention on a single server, Zhao et al., OSDI’20 Papers-we-love is hosting a mini-event this Wednesday (18th) where I’ll be leading a panel discussion including one …
A practical deep dive into Tailscale exit nodes: route changes, traceroute evidence, DERP fallback, trust boundaries, and why this model can be free.
This was unavoidable, given my post from the other day about how to make traceroute display (almost) arbitrary strings.
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…
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…
This guide shows you how to set up session recordings for Tailscale SSH. Learn how to record the terminal output whenever someone on your tailnet initiates a Tailscale SSH connection. Use these recordings to detect threats, investigate security incidents, and remain compliant with your network security policies.
Voice Chats first appeared in December, adding a new dimension of live talk to Telegram groups. Starting today, they become available in channels too – and there are no more limits on the number of participants. This update also brings recordable voice chats, rich lists of participants, raise hand mechanics, invite…
O bviously there have been many editorial changes at the formerly venerable Washington Post, a tawdry saga which I don’t intend to recap here.
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 ……
A team of engineers at the University of California San Diego has demonstrated for the first time that the Bluetooth signals emitted constantly by our mobile phones have a unique fingerprint that can be used to track individuals’ movements.

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.

These days the internet as a whole is mostly constructed out of point to point ethernet circuits, meaning an ethernet interface (mostly optical) attached directly from one routing device to another routing device.
Update: I’ve learned a bit more and as such, see the bottom of the post for an update. I’ve been slow to update this but now that it’s seeming to be gaining a lot of traffic (lead…

Digital audio processing is a complex yet fascinating subject. Getting a deeper understanding requires knowledge in multiple technical disciplines, including physics, electrical/electronical engineering, and some software engineering when it comes to parts of the Linux ecosystem. This article aims to demystify the…
Network data from the NetBlocks internet observatory confirm that Iraq has introduced a nighttime internet curfew, consistent with reports from IT industry workers in recent days. Confirmed: #Iraq has partly ...
Solving the conflicting subnet problem with overlay addressing, WireGuard, and 1:1 NAT.
In this blog series, I hope to summarize what Kafka and MQTT are and how they can both fit into an IoT architecture.
New technology will extend Wi-Fi® solutions for the Internet of Things
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…

I am pleased to preview 'Dead Drops' a new project which I started off as part of my ongoing EYEBEAM residency in NYC the last couple weeks. 'Dead Drops' is an anonymous, offline, peer to peer file-sharing network in public space.
