Our investigation uncovers two sophisticated telecom surveillance campaigns and, for the first time, links real-world attack traffic to mobile operator signalling infrastructure.

10Gb/s Ethernet: what I did to get it working in my home
I already had 2.5Gb/s working. Here's how I upgraded the whole house to 10Gb/s Ethernet -- including real iperf3 numbers, MikroTik switches, scary thermals, and what actually worked.

Networking changes coming in macOS 27
We are under warning that macOS 27 is likely to remove support for AFP, and lately some additional requirements for connection to certain servers. This explains how these could affect you.

New 10 GbE USB adapters are cooler, smaller, cheaper
For years, the best way to get 10 gigabit networking on laptops was to buy an expensive, large, and hot 10 GbE Thunderbolt adapter. With new RTL8159-based 10G USB 3.2 adapters coming onto the market, the bulky adapters might be a thing of the past. Just look at the size of the thing in comparison to my Thunderbolt…

Email could have been X.400 times better
X.400 promised recallable, scheduled, self-destructing email. Why simple SMTP won instead, and what we lost and gained when it did.

Internet Protocol Version 8 (IPv8)
Internet Protocol Version 8 (IPv8) is a managed network protocol suite that transforms how networks of every scale -- from home networks to the global internet -- are operated, secured, and monitored. Every manageable element in an IPv8 network is authorised via OAuth2 JWT tokens served from a local cache. Every…

We have a 99% email reputation, but Gmail disagrees
Oooooh boy. Let’s get this out of the way first. Email sucks. Now to the how and the why. We’re builders. We love making tools to help designers and developers live a little bit easier. We’re pretty good at it. Marketing, though? We do our best, but the truth is, we don’t like to bother […]

Blackholing My Email

A macOS bug that causes TCP networking to stop working after 49.7 days
At Photon, we are developing the world’s most complete iMessage API (with RCS and SMS fallback) for agents: infrastructure that lets Agents reliably communicate through one of the most native messaging interfaces people already use. While building it, we run Mac-backed systems continuously and care a lot about making…

Understanding Traceroute
I never understood how traceroute discovers each hop. Turns out it's a clever TTL trick, and about 80 lines of Rust.

Build your own Dial-up ISP with a Raspberry Pi
Last year my aunt let me add her original Tangerine iBook G3 clamshell to my collection of old Macs1. It came with an AirPort card—a $99 add-on Apple made that ushered in the Wi-Fi era. The iBook G3 was the first consumer laptop with built-in Wi-Fi antennas, and by far the cheapest way to get a computer onto an 802.11…

SSH certificates: the better SSH experience
When I ssh into a server for the first time, I’m confronted with a dialog which asks me to verify I’m actually talking to the machine I expect to be talking to. $ ssh -l jp 192.0.2.65 The authenti...

We intercepted the White House app's network traffic
We set up a MITM proxy and captured the decrypted HTTPS traffic from the official White House iOS app. On a single browsing session it contacts multiple Elfsight domains, sends your device fingerprint to OneSignal, and loads Google DoubleClick ad tracking. The privacy manifest says it collects nothing.

What changes when you turn a Linux box into a router
I think it is incredibly cool that we can change a Linux system into a networking device. But have you ever wondered:

How to turn anything into a router
I don’t like to cover “current events” very much, but the American government just revealed a truly bewildering policy effectively banning import of new consumer router models. This is ridiculous for many reasons, but if this does indeed come to pass it may be beneficial to learn how to “homebrew” a router…

You can run a DNS server (2025)
In case you were wondering whether this would mean... writing zone files with some arcane syntax that BIND 9 is apparently famous of, I hereby present the main point of this post a recommendation for which DNS server to choose.
