The history of Lisp alvin February 4, 2017 - 9:34pm

I’ve been interested in the Lisp programming language since I first learned about it, but in the books I’ve read about it, no author has explained the background of terms like cons, car, cdr, and S-expressions. Tonight I found this “History of Lisp” document, which explains the meaning of some of those names.

(If you’re really interested in those terms, this Wikipedia page describes them even more.)

The Hidden Fortress (influence on Star Wars)

The movie The Hidden Fortress is said to have a major impact on the Star Wars series. From Wikipedia: “George Lucas has acknowledged the heavy influence of The Hidden Fortress on Star Wars, particularly in the technique of telling the story from the perspective of the film's lowliest characters, C-3PO and R2-D2. Lucas's original plot outline for Star Wars also had a strong resemblance to the plot of The Hidden Fortress, which would be reused for The Phantom Menace.”

Dan Bricklin: The history of VisiCalc and other things

Dan Bricklin, inventor/creator of VisiCalc, the first spreadsheet program for personal computers, has created this page of historical notes and images about his work. His work came long before my interest in computers and programming, so I enjoy reading about it from a historical perspective. He shows a TI calculator and very large state diagram on this page. I remember seeing calculators like that in stores, and the work he put into the state diagram looks like a modern mind map.

If you’re into history, it’s all very cool.

Android: How to go back to Google App stories after closing the Now card alvin October 27, 2016 - 9:35am

I like the “Google” app on Android — the thing you see if you swipe right on the Android home screen. But a weakness of it is that you can’t get back to a story easily. For instance, this morning I followed a Google Now card to see a story about Tom Ricketts and the Cubs, closed the story, then thought, “Wait, I meant to look at XYZ in that web page.” Once you close a story like this the Now card disappears, and you can’t get back to it easily (which is the weakness).

Solution 1: Going back to Google Now app stories on Android 7

I don’t know if this is the only way to do it, but as a solution, one way to get back to the story on Android 7 is to follow these steps:
