How much do you know about how the PSTN (that is, the public telephone network) works? At some point long long ago, it was signalled using in-band frequencies, which facilitated the infamous phreaking using so-called “blue boxes”. This led to a switch to out of band signalling, ultimately culminating in something…
From time to time I need to expose a development web site or web service to the world. In the past, I’ve used ngrok for that, and of course long ago I built ReverseHTTP which is somewhere in the same ballpark, but I recently got fed up with the state of affairs and decided to see whether there was something simple I…

Today, in theory, you can use any Unicode character you like as part of a domain name, including emojis…

I was recently rewarded a total of $107,500 by Google for responsibly disclosing security issues in the Google Home smart speaker that allowed an attacker within wireless proximity to install a "backdoor" account on the device, enabling them to send commands to it remotely over the Internet, access its microphone…
