bobbyloxon Alternatives to Regular Expressions

One alternative in the Wolfram Language is called StringExpresions. For instance, something like

StringReplace["Mad Hatter", "M"|"H"~~a_~~b_..:>"B"<>a<>"g"]

returns "Bag Bager"

The nice thing is that a string expression can use a RegularExpression as part of the pattern, but it's often not neccesary.

I'm working on a project which you might find of use in a little while: http://codemancergame.com/

Another question: when he uses the CNC to move the sensor around, isn't he also changing the reflective surfaces in the environment? Would this not produce inaccuracies?

bobbyloxon Classic arcade game TRON on a cloth modelling grid

Cool demo. Turns out it kind of ruins the game because it makes the task of timing turns so much harder, but there was no way of knowing that until you tried it :) Great experiment, though!

bobbyloxon Ask HN: What are you working on right now and why is it cool?

A fantasy videogame that teaches programming (within the game referred to as magic) to kids, and especially girls. http://codemancergame.com

It's cool for many reasons. 1. It's a game, so that's cool. 2. Magic is programming (and vice versa)! I invented a minimal visual programming language for the game. 3. The current cultural context for technology is forbidding to some, so pulling the skill-building out of that context, and into a fantasy world, is more inclusive than most ways of getting started in programming. 4. An author is working on a companion book to go along with the game. 5. I've also promised an online course, 'Python for Codemancers' that will help people who beat the game transfer their skills into a real-world programming language.

bobbyloxon A Fantasy Videogame that teaches the Magic of Code

I'm the creator of the project, and I'm happy to discuss it. Any thoughts about the project itself? The presentation? Anything you'd like to know that isn't clear?

bobbyloxon Ask HN: Users who register but never use your web app

It sounds like you're requiring users to sign up too early. Why not try to figure out what information they can only get by signing up and giving that to them up front? It doesn't add to your numbers, but it may lighten your memory load.

bobbyloxon Ask YC: What Is Your Favorite Board Game?

Mousetrap was my favorite. I pretty much ignored the actual game though...
