> After I had translated Lovelace’s program into C, I was able to run it on my own computer. To my frustration, I kept getting the wrong result. After some debugging, I finally realized that the problem wasn’t the code that I had written. The bug was in the original!
> In her “diagram of development,” Lovelace gives the fourth operation as v5 / v4. But the correct ordering here is v4 / v5. This may well have been a typesetting error and not an error in the program that Lovelace devised. All the same, this must be the oldest bug in computing. I marveled that, for ten minutes or so, unknowingly, I had wrestled with this first ever bug.
> Jim Randall, another blogger that has translated Lovelace’s program into Python, has noted this division bug and two other issues. What does it say about Ada Lovelace that her published program contains minor bugs? Perhaps it shows that she was attempting to write not just a demonstration but a real program. After all, can you really be writing anything more than toy programs if you aren’t also writing lots of bugs?
Lunch: coffee, Thai
