Tracking Blood Sugar
Fasting glucose and A1C tests done over the past few years show me at low risk for diabetes. But these tests don’t necessarily capture how much blood sugar “spikes” after meals–something that may be a better predictor of disease risk . Such blood sugar spikes can be minimized with a suitable diet, but what that diet…

Re-decentralizing the Web, for good this time
Originally designed as a decentralized ecosystem, the Web has undergone a significant centralization in recent years. In order to regain control over our digital self, over the digital aspects of our lives, we need to understand how we arrived at this point and how we can get back on track. This chapter explains the…

You Weren't Meant to Have a Boss (2008)
March 2008, rev. June 2008 Technology tends to separate normal from natural. Our bodies weren't designed to eat the foods that people in rich countries eat, or to get so little exercise. There may be a similar problem with the way we work: a normal job may be as bad for us intellectually as white flour or sugar is for…

Using Fourier Transforms to Multiply Numbers
The purpose of this article is to show you step-by-step examples of how to use the Fourier transform algorithm to multiply two numbers.

Personal Finance Lessons for Technology Professionals
> Patience. Frugality. Sacrifice. When you boil it down, what do those three things have in common? Those are choices. Money is not peace of mind. Money’s not happiness. Money is, at its essence, that measure of a man’s choices. This is part of the opening monologue of the

Thoughts on Rust, a few thousand lines in
To say my first foray into Rust was a frustrating struggle would be an understatement. I picked a terrible first project that left me neck deep in Rust’s trickiest areas right off the bat. I was excited to try again. A few years ago I wrote Sumoshell, a CLI App for log analysis. I’d wanted to improve it for a while…

The State of Software Security in 2019
My goal in this post is to skim my observations on the state of software design and development over the past year, and to try to find a meaningful way forward for myself for 2019. My perspective is limited by the fact that I have worked exclusively in client-side software security for the past 7.5 years. Still, I…

Why I Am Not an Austrian Economist

The summer before I began my undergraduate work at UC Berkeley, I was able to attend the 1989 Mises Institute summer seminar at Stanford, where I met Murray Rothbard and…

Monorepos and the Fallacy of Scale
In a recent blog post entitled “Monorepos: Please don’t,” Matt Klein discusses the pros and cons - as it turns out, mostly cons in his view - of monorepos. The long and short of it is that he thinks that they are not a good fit for most teams. After thinking about this question for a few years I have come to the…

Warning Signs in Experimental Design and Interpretation (2007)
When an experimental study states "The group with treatment X had significantly less disease ( p = 1%)", many people interpret this statement as being equivalent to "there is a 99% chance that if I do treatment X it will prevent disease." This essay explains why these statements are not equivalent. For such an…
