Kids Pass Just Reminded Us How Hard Responsible Disclosure Is
Only a couple of months ago, I did a talk titled "The Responsibility of Disclosure: Playing Nice and Staying Out of Prison". The basic premise was to illustrate where folks finding security vulnerabilities often go wrong in their handling of the reporting, but I also wanted to show how organisations

News reports tell us that Customs and Border Patrol has become more aggressive about checking social media accounts at the border. In doing this, the United States joins a growing list of countries that recognized the value of these accounts, and the unique data mining opportunity that a border crossing provides.

Finding Free Food with Python
If you live in a major city, there’s a good chance you’ve used (or at least heard of) food delivery services like Postmates, GrubHub, or DoorDash.

Building a Distributed Log from Scratch, Part 1: Storage Mechanics
The log is a totally-ordered, append-only data structure. It’s a powerful yet simple abstraction—a sequence of immutable events. It’s something that programmers have been using for a very long time, perhaps without even realizing it because it’s so simple. Whether it’s application logs, system logs, or access logs…

Uncle Bob and Silver Bullets
A while back I wrote that Robert Martin was ruining software by being too good at programming. That was supposed to be a joke.

What’s a fire, and why does it burn?
I was staring at a bonfire on a beach the other day and realized that I didn’t understand anything about fire and how it works. (For example: what determines its color?) So I looked up some s…

Ansible open-sources Ansible Tower with AWX
Ever since Red Hat acquired Ansible, I and many others have anticipated whether or when Ansible Tower would be open sourced. Ansible Tower is one of the nicest automation tools I've used... but since I haven't been on a project with the budget to support the Tower licensing fees, I have only used it for testing…
