Learnings from 5 years of tech startup code audits

While I was at PKC, our team did upwards of twenty code audits, many of them for startups that were just around their Series A or B (that was usually when they had cash and realized that it’d be good to take a deeper look at their security, after the do-or-die focus on product market fit).

On rebooting: the unreasonable effectiveness of turning computers off and on again

The mindless tyranny of 'what if it changes?' as a software design principle

"What if it changes?" isn't just a question. It's a powerful heuristic for software design that can be used to justify almost anything. Everyone should use it more. It's great precisely because it's rooted in pure speculation. Once you've freed yourself from the baggage of reality, there's nothing easier than inventing scenarios where your special code will be useful under the new imaginary future conditions. If you encounter any pushback against your defensive layer cake of abstraction, interfaces, or ham-fisted design patterns, don't fret – they can't actually prove that the future you predict won't happen. That's the magic of the design rationale: the only way to fight speculation is with further speculation. You're both making the same gamble.
