Interestingly, the Ur-Lisp (Lisp 1.5) actually had both. There were two ways to define a function. There was one form, LABEL (the ancestor of CL's LABELS), which bound a function like a variable, and another form, DEFINE, that put the

The HTML5 standard prescribes a regex for implementers to validate email addresses on the client side: /^[a-zA-Z0-9.!#$%&’*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/ So if you're going to use <input

I do this in Common Lisp. It also makes sense as a technique for documentation: why leave examples rusting in comments when you can incorporate them into the program? Add a Quickcheck-ish type-based test case generator and you start to blur

Clojure's persistent vectors and hashmaps are both the same data structure, the hash array mapped trie, which can be implemented both simply and efficiently. If you look at the Java code in the Clojure source, there are no tricks, beyo

How do you account for disagreeing, not with someone's conclusions, but with the means that they used to arrive at them? I usually think it in vain to post a comment on something that I fundamentally disagree with, because I rarely find an

The lesson itself is less troubling than these teachers' undertaking to shape the children's beliefs without any parental involvement or input--not, note, as part of a curricular course of study at a school, but in an after-school program a
