How to build an absurdly backwards-compatible website
Let's face it: the internet is broken. It feels like so much of the web is composed of clickbait, ads, popups, and a toxic amount of JavaScript that you need a modern computer just to get any value out of it. Remember when low-power computers were created for people who were "just browsing the internet?"…

A Fairly Fast Fibonacci Function
A common example of recursion is the function to calculate the $n$-th Fibonacci number: def naive_fib(n): if n < 2: return n else: return naive_fib(n-1) + naive_fib(n-2) This follows the mathematical definition very closely but it’s performance is terrible: roughly $\mathcal{O}(2^n)$. This is commonly patched up with…

R7RS versus R6RS (2018)
InPhase asked today on #scheme about the R7RS vs R6RS debate. I followed the original debate closely and have experience both using and implementing R6RS. I also recently added R7RS support in Akku.scm 0.3.0, so I feel like I can weigh in on this. It’s a topic that many feel passionately about, and I’m also firmly on…
