I’ve made another one of my interactive online maths doodads. You should have a go at it right now. It doesn’t require any effort on your part, other than coming up with a positive integer.

A little bit of news for those who, through necessity or ignorance or unique personal whimsy, use a WYSIWYG editor for putting equations into computers.
WIRIS, whose technology is used in things like the virtual learning environment Blackboard, have bought Design Science, makers of MathType. MathType became the de facto standard equation editor for Microsoft Word back before its built-in solution was any good, but has somewhat stagnated recently. The press release says, “by combining our teams we will now be able to offer education, scientific and publishing communities newer products at a fast pace”. I think that’s a long way of saying they’re not going to duplicate their efforts any more.

Mastodon is a new social network, heavily inspired by Twitter but with a few differences: tweets are called toots, it’s populated by tusksome mammals instead of little birds, and it’s designed to run in a decentralised manner – anyone can set up their own ‘instance’ and connect to everyone else using the GNU Social protocol.
Colin Wright and I both jumped on the bandwagon fairly early on, and realised it might be just the thing for mathematicians who want to be social: the 500 character limit leaves plenty of room for good thinkin’, and the open-source software means you can finally achieve the ultimate dream of maths on the web: LaTeX rendering!
MathJax, the web library that provides LaTeX-quality mathematical typesetting, has received a a new set of tools to improve accessibility of mathematical notation. The new MathJax Accessibility Extensions add on-the-fly speech rendering of notation, and a tool to explore expressions through intelligent collapsing and expanding of sub-expressions.
Around about exactly this time a year ago, I bought the frivolous domain name three.onefouronefivenine.com, to celebrate π Day and to indulge my curiosity about a marvellous algorithm to compute π’s digits.
This year, I’ve been thinking about prime numbers, and my hosting provider has run another sale on domain names. So, I’ve bought isthisprime.com. You can probably guess what I’ve made it do.
Plot.ly is a fairly comprehensive tool for creating whizzy interactive charts from data. It provides a suite of tools to make a whole range of different types of charts.
Until now, it’s been a web service you send data away to in order to get a chart back. I’d always been wary of that, because I worry about what happens when Plotly the company gets sold off or goes bust, and plot.ly the service gets shut down.
Well, now I can use a little bit of plot.ly, because they’ve released the bit of the chart-drawing code that runs in your browser under the MIT open source licence, meaning anyone can use it independently of Plotly’s servers.

I’ve put a very clever horse on the internet. He’s called Hans and I’ve made a little video about him.
You can ask Clever Hans your own questions! Go to christianp.github.io/clever-hans and make sure your microphone is turned on. Another proviso: I think only Google Chrome supports the special technology I used to make Hans work. Sorry!
I’ll explain how Hans does his horsey magic below the fold.
