This graph of CDN hits from jsDelivr shows that TeXMe usage goes down over the weekends in a very consistent manner. The usage peaks on Mondays and Thursdays! TeXMe is a tiny utility to create self-rendering Markdown + LaTeX documents. See github.com/susam/texme for details.

Strikethrough text on terminal with Unicode: printf "%s\xcc\xb6" h e l l o Or try this: python3 -c "print('hello'.replace('', '\u0336')[1:])" Pipe those commands through the command od -tcx1 to see what is going on. See fileformat.info/info/unicode/c… for more details.

Our 99th meeting will begin at 17:00 UTC. Yes, it is the 99th! We will see why ζ(s) = 0 for s = -2, -4, -6, -8, ..., that is, we will find the so-called trivial zeros of the Riemann zeta function. Visit offbeat.cc/#iant to get the meeting link and join us. #mathematics

Oskar Perron, a German mathematician, introduced Perron's paradox to illustrate the danger of assuming the existence of a solution to an optimization problem: Let N be the largest positive integer. If N > 1, then N² > N, contradicting the definition of N. Hence N = 1.

It took me a while to realize what this picture on the cover of the book "Introduction to Analytic Number Theory" (Apostol, 1976) really means. Special thanks to @LavaboMouille for helping me interpret this picture correctly.

My choice of colour for syntax-highlighting comments: #fc0 (tangerine yellow). It goes well with dark background. I especially dislike dim colours that underemphasize comments. I like them brightly-coloured! What is your favourite colour for comments? #programming #lisp

@fermatslibrary Note that (1 - i)/(1 + i) = (1 -i)(1 - i)/(1 + i)(1 - i) = -2i/2 = -i = e^(-i𝜋/2). Thus log((1 - i)/(1 + i)) = -i𝜋/2 = 𝜋/(2i). Therefore 𝜋 = 2i log((1 - i)/(1 + i)).

Inspired by a recent discussion on the #commonlisp channel of @liberachat, after many years of using Emacs + SLIME + Paredit + Rainbow Delimiters, I finally decided to take the plunge and customize Rainbow Delimiters to change its default muted colours to something more lively!
