# One Day in the Centre of Computing History

It was my third day in Cambridgeshire, and it was an adorable sunny day. After looking it up on Google Maps, I decided to go The Centre of Computing History, which attracted me at first glance on the map.

And it turned out to be a wonderful experience there! Basically you can actually get your hands on those old computers, from the 70s all the way to the 90s. They even have some working punch tape machines!

And here is the encode/decode table~ The whitespace is shown as ␣ to avoid vertical mismatches. The small dot . is used for locating the horizontal line and speed. And the big dot • denotes the actual punched hole on the tape.

# Here's to the crazy ones

Here's to the crazy ones: the misfits, the rebels, the troublemakers, the round pegs in the square holes, the ones who see things differently.

They are not fond of rules. They have no respect of status quo. You can quote them, disagree with them, glorify or vilify them. About the only thing you can't do, is ignore them, because they change things. They push human race forward.

Some may see them as the crazy ones. We see genius，because the people who are crazy enough to think they can change the world ... are the ones who do.
