Operations in Lisp, Scheme, and other dynamically-typed languages typically dispatch on representational type information rather than intentional type information. Several broad classes of bugs and confusions can be traced to improper attempts to recover intentional type information from representation types.

Update: (November 2015) In the almost seven years since writing this, there has been an explosion of great tools for automatic differentiation and a corresponding upsurge in its use. Thus, happily,…

We have identified a vulnerability in the Internet Public Key Infrastructure (PKI) used to issue digital certificates for secure websites. As a proof of concept we executed a practical attack scenario and successfully created a rogue Certification Authority (CA) certificate trusted by all common web browsers. This…

Random code snippets, projects and musings about software from Eric Kidd, a developer and occasional entrepreneur.
Statistical and applied probabilistic knowledge is the core of knowledge; statistics is what tells you if something is true, false, or merely anecdotal; it is the "logic of science"; it is the instrument of risk-taking; it is the applied tools of epistemology; you can't be a modern intellectual and not think…

This is the first post in an article series about this course. As I wrote earlier, I am very serious about watching video...
Studying prime numbers is like playing the guitar. No, really, let me explain. The guitar is a simple instrument: six strings, some frets,...

For this one talk I wrote the following script, though (being hard to break the habits of 30 years) I didn't stick closely to the script. Each link is one slide.
Continuing the theme of alternative approaches to teaching calculus, I take the liberty of posting a letter sent by Donald Knuth to to the Notices of the American Mathematical Society in March, 199…
