It’s november, and I’ve decided this month that I’m going to do 30 projects in 30 days. It’s an all-month hack-a-thon!

Today’s project is Hack-A-Machine (demo, source). It’s a whimsical VM you can play around with.

I liked this one, but it really didn’t fit into a day too well.

Features include:

• Edit, save, and share programs!
• Visual debugger with step, run, pause, and stop!
• One example program!
• Weird arithmetic!
• Negative-364 based addressing!
• “Touchscreen” display!
• “Ticker tape” input and output!
• 21 never before seen instructions!
• Optional registration!

Sadly not in the “one day” category are

• good compiler errors
• line numbering
• line highlighting when stepping through code
• syntax highlighting
• the entire machine 100% working (I tested a little!)
• fixing all the bugs (there’s a particularly nasty one where you have to save before you run)
