Somebody posted the challenge to change one letter in a book title and ruin it. Naturally, I decided the computer should help come up with the bad suggestions. The page has an embedded dictionary and a small JavaScript search. For each word in the title, it tries replacing one character at a time with another […]
I made a browser map of our family Minecraft world. It is fun to look around at everything we have built without actually logging into Minecraft. This uses Minecraft Overviewer to turn the saved world into isometric image tiles. The browser only needs the tiles for the part of the world you are looking at, […]
I put together a status page for our family Minecraft server. It is a simple way to answer the first question before trying to join: is the server actually running? This is mostly integration work rather than a new Minecraft protocol implementation. The PHP page asks the MineTools ping and query endpoints for JSON, then […]
I keep making little bookmarklets and then forgetting the annoying part of turning JavaScript into a usable Favorites link. So I made a page to do that part for me. Paste in the script and it builds a link with the javascript: prefix, along with the address text to copy. The code squeezes out some […]
I came back to the permutations page and gave it a textbox and a button. It is a small improvement, but changing the address every time I want to try a different string gets old. The algorithm is still the same recursive one: pick each character in turn, permute the rest, and collect the completed […]
I made a little equation solver for questions like 1_2_3_4_5=6. The numbers are already there; the puzzle is deciding which operations go in the spaces. The code recursively builds combinations of plus, minus, multiply, and divide, puts each combination between the numbers, and evaluates the result. For the default example, it finds answers such as […]
Shantell wanted her Facebook bookmark to make her solve a math problem before letting her in. That sounded like a perfectly reasonable little programming project. 🙂 I made it as a bookmarklet instead of a browser extension. The bookmark runs a small JavaScript function, asks a randomly generated multiplication or percentage question with prompt(), and […]
