One of the more obscure things I can do is program readerboards. Those LED kind of displays you see under a big business sign that scroll images, show what’s on sale, display the time and temperature, and so on.
Problem is, most readerboard software I’ve had to use is complete junk. They’re horribly unstable, crash often, and are not put together in any form of English I’m aware of.
The thing is I don’t know anybody else who does this. Most of the bigger companies have someone specifically fly out from corporate relations to change their readerboards, and they don’t like to talk about what they use. If they’re a franchise, they just stick a memory card the corporate office sends them into the feeder computer to update the screen.
