To @AndrewHart: “Our app is shit and we know it’s shit”. My life changed forever when a senior exec from one of the world’s largest retailers messaged me on Twitter. This was back in 2017. My outdoor AR navigation demos had just gone viral, and my new open-source project for...

The Matrix.org network has great potential, but after years of dealing with glitches, slow performance, poor UX, and one too many failures, I’m done with it.

This post is written by a human being (me).
Post describing how I've configured pihole to return different results to clients on my tailnet than those on the LAN.
I love DNS esoterica. Weird little things that you can shove in the global directory to be distributed around the world instantly(ish). Domain names, like www.example.com usually resolve to servers. As much as we think of "the cloud" as being some intangible morass of ethereal Turing-machines floating in probability…
In this article I want to document my journey implementing fast TCP fingerprinting in a golang webserver, using eBPF.
A technical blog about Rust, Linux and other topics.
There are secret messages flying all around you all the time, being transmitted via, most of the time, electromagnetic waves going from antenna to antenna. ELOs “Secret Messages” is a song about posting conspiracy theories via WiFi. But what if you need to get a few bytes from device A to device B (one of the hard…
So I was uh, downloading some linux isos, like usual. It was going slowly, so I opened up the Trackers tab in qBittorrent and saw the following:

Thanks to war, geopolitics, and climate change, Europe will have more frequent and more severe internet disruptions in the very near future. Governments and businesses need to prepare for catastrophic loss of communications. Unfortunately, the necessary changes are risky and expensive, which means they won’t do it…
The Netscape/Microsoft browser wars in the mid-90's were really vicious and competitive. They really had it out for each other. Netscape had...
The Starlink Mini terminal is designed as a compact, all-in-one solution with an integrated Wi-Fi router. While this design is ideal for typical consumer use, certain applications—such as custom networking setups, embedded installations, or power-constrained environments—may benefit from removing the internal router…
This is another post that started after several toots on mastodon. Most of the things presented here were already tooted by other people, but I think this is a good chance to write a mini tutorial about what to look at. We’ll use DNS, whois, BGP and your favourite search engine. What is DNS4EU? To quote the web page…
Update 6/10: Based on a short conversation with an engineering lead at X, some of the devices used at X are claimed to be using HSMs. See more further below. Matthew Garrett has a nice post about T…
DoH is not about protecting your DNS queries from peepers. That is a big lie. It is about making sure only one peeper can see all of your queries.
Solving a boot-time power challenge on PoE+ x86 systems by creating our own UEFI app to handle LLDP power negotiation at the firmware level, allowing our machines to request higher power from network switches before the OS loads.
At 7AM (UTC) on Tuesday May 20th 2025 a BGP message was propagated that triggered surprising (to many) behaviours with two major BGP implementations that are often used for carrying internet traffic.
Mostly to make use of an animation I made for a different blog post that hasn't materialised, let me take a moment to explain to you the fundamental technical difference between 'streaming' and 'downloading'. Which won't take long... because there isn't one!
Air traffic control has been in the news lately, on account of my country's declining ability to do it. Well, that's a long-term trend, resulting from decades of under-investment, severe capture by our increasingly incompetent defense-industrial complex, no small degree of management incompetence in the FAA, and…
One of my longest-running projects has been an open hardware Ethernet switch. This has been one of the key driving forces behind many of my other projects, such as ngscopeclient and the high speed probes. It was also the project that got me into high speed digital design.
It was launched to measure moisture. Now it’s ghost-trailing jammers across an electronic battlefield.
Why Pi-hole, the Raspberry Pi DNS sinkhole, is worth running at home to block trackers, ads, and analytics endpoints across every device on the network.
(Hat tip to the late Bill Strauss and The Capitol Steps' Lirty Dies.) A few moons ago I was thinking of ways to take my Palm OS Fossil Wr...
Have you ever looked at an NVMe drive and thought to yourself, 'Hey, this would be 31.7% cooler with HDMI ports?'
At Revision 2025, we released "Signal Carnival" ( csdb , YouTube ). This demo asks you to switch the audio and video cable of your C64:
