Heads-up: An update to this article has been posted. There have been a lot of complaints about both the competency and the logic behind the latest Epstein archive release by the DoJ: from censoring…

Vital personal and business information flows over the Internet more frequently than ever, and we don’t always know when it’s happening. It’s clear at this point that encrypting is something all of us should be doing. Then why don’t we use TLS (the successor to SSL) everywhere? Every browser in every device supports…
It all begins with one scary email late at night just before I had to go to sleep:
New versions of Brave will hide—and, where possible, completely block—cookie consent notifications. Brave's approach is distinct and more privacy-preserving than similar systems used in other browsers.
Oblivious DoH (ODoH) makes secure DNS over HTTPS (DoH) queries into private queries which prevent the leakage of client IP addresses to resolvers. The new proposed ODoH standard addresses this problem and today we are enabling users to use this protocol with 1.1.1.1

Last year, I posted a series of articles about a purported “breach” at Ubiquiti. My sole source for that reporting was the person who has since been indicted by federal prosecutors for his alleged wrongdoing – which includes providing false information to the press.

It’s the first half of 2021 – nearly five years since the “first half of 2016” – but in many ways not much has changed. The United Kingdom is still trying to figure out Brexit, another Justin Bieber song hit #1 on the charts (is it too late now to say sorry?), and Signal still doesn’t really know...
Software distribution has over the years gone through an enormous revolution in efficiency. Originally, software was developed on things called ‘plug boards’, a matrix of sockets that allowed quick (or so they thought) re-configuration of computing hardware to adapt it to different problems. This was soon followed by…
I recently started verifying user email addresses during signup to prevent bots, mistyped emails, and also to ensure that addresses are…
This morning, I spent an hour in a closed room with six members of Congress: Rep. Lofgren, Rep. Sensenbrenner, Rep. Bobby Scott, Rep. Goodlatte, Rep. Mike Thompson, and Rep. Amash. No staffers, no public: just them. Lofgren had asked me to brief her and a few Representatives on the NSA. She said that the NSA wasn’t…
