I had time to take a walk before running some errands and getting a flu shot and a Covid booster this morning. ⌘ Read more
** A playground for sharing scrappy fiddles **
I shared some snippets of JavaScript in a recent blog post and was wicked irked that I didn’t have an easy way to share interactive code on my own thing…so… I made a totally static JavaScript playground for running little experiments and sharing scrappy fiddles!
It is pretty simple — it allows folks to enter and run JavaScript, includes a console so you can easily log thing … ⌘ Read more
** Constants, variable assignment, and pointers **
After reading my last post, a friend asked an interesting question that I thought would also be fun to write about!
They noted that in the reshape function I declared the variable result as a constant. They asked if this was a mistake? Because I was resigning the value iteratively, shouldn’t it be declared using let?
What is happening there is that the constant is being declared as an array, so the reference … ⌘ Read more
** Reshape, in JavaScript and APL **
In APL the rho, ⍴, called reshape is used to both construct arrays of a given shape (dimensionality), and to reconfigure arrays into new shapes.
Sometimes I wish I had reshape in JavaScript…so I wrote it!
Here are two functions that, when combined, a la Captain Planet, can stand in for APL’s reshape in JavaScript.
Ravel is the simpler of the two, it takes an array of any dimension and ret … ⌘ Read more
** September summer **
I finished reading Robin Sloan’s Moonbound today. It was fun, and light. The blurb likens it to Narnia, and, while a bold claim, I think that was a correct assertion, but more about the intended audience than the book’s subject matter. If a sequel is ever written I’d most certainly give it a look. It seems like a great gift book for a kid between like 8 and 15…or you know, perhaps, anyone who likes fun stories that aren’t scared of bein … ⌘ Read more
