Here’s an example on the MDN page about text fragments.| And now it’s all this
As I often do, I thought it worthwhile to put up a quick post showing how I made the graphics in my previous post. The images were made in Mathematica, mainly through the Graphics3D command. The exception was the plot of 10,000 random points; that was done through ListPointPlot3D.| And now it’s all this

As I said back in June, one of my goals for my library search system (recently updated) was to be able to check on whether I already owned a book while in a used bookstore. I got to use it for that very purpose a couple of days ago, and it worked just as I hoped.| And now it’s all this
Last year, I complained about Apple’s way of calculating and presenting trends in the Health app. Today I’m going to complain about how it handles trends in the Fitness app. I like to spread my complaints around.| And now it’s all this
