Before software controlled the world, we couldn't even agree how to spell it.

In the 1950s & 1960s, it was spelled 2 ways:

• softwear
• software

Even companies hiring coders couldn't decide.

Going to the Moon helped settle that question.

2/ And what about writing computer code?

Was it an art? a talent, like writing?

Was it a science, like math?

The software that flew to the Moon had to be perfect, and perfectly understood.

So Apollo helped turn software into an engineering discipline.

3/ That's #14 in my series about what it took to get to the Moon in the 1960s, '50 Days to the Moon,' @FastCompany.

50 stories, written in 50 days, last summer — to celebrate the 50th anniversary of the first Moon landing on July 20, 1969.

4/ This summer, we need a reminder of what Americans are capable of, when we work together with a clear goal in mind.

Nothing gave software engineering focus and discipline like having to use computer code to fly to the Moon.

5/ If you write code, you'll appreciate this:

Apollo flight code was the world's 1st large software project. Run by MIT, at the peak it required 700 people, coding 2 computers, for 11 missions.

And MIT's 1st cut was 40% too large. The code did not fit in the computers.

6/ Apollo changed the world of computing.

But it probably would be working the same if we spelled it softwear.

7/ The whole series of 50 stories on what it took to get to the Moon is @FastCompany.

The stories are short. There are some crazy moments.

>NASA wanted to use a rope to get to the Moon's surface.

>The space race invented the computer beep.

8/ Spelling it 'softwear' held on for quite awhile.

Here's the New York Times using it that way, in a headline, in January 1984.

9/ And by the way, the legendary picture below?

That's MIT software coder Margaret Hamilton, next to a printout of the entire flight code for one Apollo mission.

(Hamilton ended up as a senior manager at MIT, but she didn't, as some captions put it, write all the code.)
