Here is a little dictionary experiment: give every letter a number, with A equal to 1 and Z equal to 26, and add up each word. I wanted to see which words landed on multiples of 26. The page carries a big word list right in the HTML. JavaScript walks through it, skips entries containing […]
I played with the web video remote again and gave it a few more things to do. In addition to Play and Pause, it can slow the video down, speed it up, or jump back ten seconds. Sometimes rewind is the most useful button on a remote. It still uses a very small PHP mailbox […]
I have been working through interview-style programming questions and wrote a little page to generate permutations of a string. Give it 1234 and it prints all twenty-four arrangements. The recursive step is pretty simple: choose a character, find all the permutations of what is left, then put the chosen character at the beginning of each […]
I have been playing with Box2DWeb and made a little slicing demo. Drag a line through one of the shapes and it breaks into pieces that keep falling and bumping into everything else. It is surprisingly entertaining for something that does not really have a game attached to it yet. Box2D handles the physics. The […]
I made a testing page for cross-origin requests in IE10 and Windows 8. CORS is one of those things where a tiny difference in a header can completely change what the browser lets you do. I wanted to be able to change one thing at a time and actually see what happened. The client uses […]
I wanted to see how little code it would take to control a video from a different device. Open the video page on one computer, open the remote page on another, and use the Play and Pause buttons there. The video is an HTML5 <video> element. The remote sends a command to a PHP script, […]
I made a simple chat app to play with the browser-to-server part of a web page. It is not trying to replace anything. I mostly wanted to get a message from one browser onto another screen. The page uses jQuery to post a message to PHP. PHP appends it to an HTML log, and the […]
