Dean Hickerson conjectured (A126236) in 2006 that the following fact holds about Huffman codes: Suppose that [math] is the maximum length of a codeword in Huffman encoding of [math] symbols, where the [math]-th symbol has frequency [math].

Modern software finds it tempting to liberally use dynamic memory allocation.

Suppose that we wanted to query for values of Fibonacci numbers up to [math] for some fixed upfront [math].

Hosting a website in 2026 is a huge pain in the ass.

Back in July of 2021 I wrote a blog post that claimed a relationship between the inequality [math] and the Gregorian leap-year rule.

Before we start. ⎇ Last week has been quite eventful to me.

Not that long ago I became aware of Justine Tunney's cosmopolitan libc project.

Many years ago, back when I was in my early teens, I picked up an interest in math.

Programmers often see regular expressions and the respective matching engines as a complex, almost unattainable blackbox.

Introduction ⎇ The INSAG-1 report on the Chernobyl accident, published in August 1986, was based on preliminary information available at that time.

Most chat apps are centralised, corporate-owned and unwilling to compromise on client choice.

The landscape of computer science, programming, and related careers has changed dramatically since I first took an interest in it.

Shannon's seminal paper "A Mathematical Theory of Communication" introduced the concept of entropy as a measure of information.

Preliminaries ⎇ The Fibonacci numbers are defined by the recurrence: [math] A closed form of this formula is given by Binet's formula: [math] where [math] and [math] are the roots of the characteristic polynomial [math].

Programs have semantic and syntactic properties.

Introduction ⎇ In high school algebra, it is demonstrated that a rational function (a quotient of two polynomial functions) can be expressed as the sum of partial fractions, which are terms of the form [math] The importance of the partial fraction decompo…
