screenshot of the hatnote visualization of Wikipedia edits
There is a wonderful STEAMy mashup application online that lets you listen to the edits being made right now on Wikipedia. How? It assigns sounds to the edits being made. If someone makes an addition, it plays a bell. It someone makes a subtraction from an entry, you'll hear a string plucked. The pitch changes according to the size of the edit - the larger the edit, the deeper the note.

In this information age steeped in computers, the engine humming under the surface of this website and much of the technology we use is full of mathematics and computer science. That means it uses algorithms. I was reading a story about how Facebook again (probably constantly) tweaked its algorithms for what we see in our news feed. What is all this about and where did it come from?
* If you want to know how to compute the RSA algorithm shown partially at the top of this post, including how to select values for d, e, n, p, q, and ? (phi), you can watch this video. It also will help insomniacs.

If you have never had the opportunity to teach online and have wondered what it's like, here's a chance to find out. Canvas offers you a chance to try out their learning management system (LMS) for free. They offer two options: Take Canvas for a test drive with a free, two-week trial account that is pre-loaded with course content so that you can explore without having to build from scratch. But, even better, is the offer to actually teach your existing class on Canvas for free, forever. "You bring the content and students. We’ll provide the awesome platform, " says Canvas.

There is global interest in teaching programming in schools. Initiatives that come from outside education, like Code.org, which is backed by Mark Zuckerberg and Bill Gates, are trying to get more students learning a second (or third) language, but it's not one that is spoken. But I also see a backlash of those who say that writing code is a terrible way for humans to instruct computers and that newer technology may render programming languages "about as useful as Latin."

Technology pulls many "new" words from other fields. there are a surprising number of terms we get from nature. I was looking through a book by Sue Thomas called Technobiophilia: Nature and Cyberspace that has me thinking about terms we use in new ways in technology.

I wrote earlier about the "Hour of Code" and about how coding is a subject not often taught in schools (at all levels) or taught in isolation and to only a small percentage of students.
