PhotoMath, a free app, lets you take a picture of an equation and get an answer plus the steps involved. (Does not recognize handwriting.) Assuming you already have it on a screen somewhere, this is easier than re-typing the mathematical expression at sites like WolframAlpha.com. PhotoMath already has 11 million downloads for the iPhone and Windows Phone version. That’s a lot of downloads but it didn’t work for us. You try it. An Android version is coming soon.
– “Lauren Ipsum” by Carlos Bueno is the story of a little girl who must find her way home by thinking like a programmer. It may do for children what Douglas Hofstadter’s “Godel, Escher, Bach” did for Joy back in the 1980s: get them excited about programming ideas. The name “Lauren Ipsum” comes from the dummy text used as filler when printers don’t have the actual text of a page yet or want to show off a font. It’s been around since the 1500s, when an unknown printer used assorted type to make a specimen book. The book’s title character tackles classic problems like “Zeno’s Paradox” and “The Traveling Salesman.” Each chapter connects to a real-life computer science lesson in […]

Spreeder.com is a free speed reading tool. Paste the text you want to read in the window on the page and the words will flash by at any speed you choose. (This reminds Bob of an old Woody Allen joke: He learned speed reading and went through Tolstoy’s massive “War and Peace” novel in six minutes. He said it seemed to be about Russia.) Because you don’t have to keep a finger on your place, you’ll find your reading speed increasing by 50 percent the first time you try it. We did. The site gives you sample text to practice with, but we went beyond that: We pasted in a bunch of text from “Tarzan of the Apes,” free at […]
CourseReport.com programmers headclaims that schools and camps teaching programming, often called “coding,” will bring in $60 million in tuition for the year and graduate 5,987 coders, a 175 percent increase over last year. Tuition can cost up to $20,000, with the average around $10,000 for courses ranging from nine to 12 weeks. All in all, this seems expensive to us.
