Geek life: Write a program in a single tweet: What can you code in 280 characters?

WANT TO GIVE YOUR CODING chops a public workout? Then prove what you can do with the BBC Micro Bot. Billed as the world's first "8-bit cloud," and launched in February, the BBC Micro Bot is a Twitter account that waits for people to tweet at it. Then the bot takes the tweet, runs it through an emulator of the classic 1980s BBC Microcomputer running BASIC, and posts a video of 3 seconds of the output. It might sound like that couldn't amount to much, but folks have been using it to demonstrate amazing feats of programming, including most notably Eben Upton, creator of the Raspberry Pi.
