Earlier today, I wrote about building a computer with Jacob, our 3.5-year-old, and setting him up with a Linux shell.
We did that this evening, and wow — he loves it. While the Debian Installer was running, he kept begging to type, so I taught him how to hit Alt-F2 and fired up cat for him. That was a lot of fun. But even more fun was had once the system was set up. I installed bsdgames and taught him how to use worm. worm is a simple snake-like game where you use the arrow keys to “eat” the numbers. That was a big hit, as Jacob likes numbers right now. He watched me play it a time or two, then tried it himself. Of course he crashed into the wall pretty quickly, which exits the game.
I taught him how to type “worm” at the computer, then press Enter to start it again. Suffice it to say he now knows how to spell worm very well. Yes, that’s right: Jacob’s first ever Unix command was…. worm.
He’d play the game, and cackle if he managed to eat a number. If he crashed into a wall, he’d laugh much harder and run over to the other side of the room.
Much as worm was a hit, the Linux shell was even more fun. He sometimes has a problem with the keyboard repeat, and one time typed “worrrrrrrrrrrrrrrrrrm”. I tried to pronounce that for him, which he thought was hilarious. He was about to backspace to fix it, when I asked, “Jacob, what will happen if you press Enter without fixing it?” He looked at me with this look of wonder and excitement, as if to say, “Hey, I never thought of that. Let’s see!” And a second later, he pressed Enter.
The result, of course, was:
-bash: worrrrrrrrrrrrrrrrrrm: command not found
“Dad, what did it do?”
I read the text back, and told him it means that the computer doesn’t know what worrrrrrrrrrrrrrrrrrm means. Much laughter. At that point, it became a game. He’d bang at random letters, and finally press Enter. I’d read what it said. Pretty soon he was recognizing the word “bash”, and I heard one time, “Dad, it said BASH again!!!” Sometimes if he’d get semicolons at the right place, he’d get two or three “bashes”. That was always an exciting surprise. He had more fun at the command line than he did with worm, and I think at least half of it was because the shell was called bash.
He took somewhat of an interest in the hardware part earlier in the evening, though not quite as much. He was interested in opening up other computers to take parts out of them, but bored quickly. The fact that Terah was cooking supper probably had something to do with that. He really enjoyed the motherboard (and learned that word), and especially the CPU fan. He loved to spin it with his finger. He thought it interesting that there would be a fan inside his computer.
When it came time to assign a hostname, I told Jacob he could name his computer. Initially he was confused. Terah suggested he could name it “kitty”, but he didn’t go for it. After a minute’s thought, he said, “I will name it ‘Grandma Marla.'” Confusion from us — did he really understand what he was saying? “You want to name your computer ‘Grandma Marla?'” “Yep. That will be silly!” “Sure you don’t want to name it Thomas?” “That would be silly! No. I will name my computer ‘Grandma Marla.”” OK then. My DNS now has an entry for grandma-marla. I had wondered what he would come up with. You never know with a 3-year-old!
It was a lot of fun to see that sense of wonder and experimentation at work. I remember it from the TRS-80 and DOS machine, when I would just try random things to see what they would do. It is lots of fun to watch it in Jacob too, and hear the laughter as he discovers something amusing.
We let Jacob stay up 2 hours past his bedtime to enjoy all the excitement. Tomorrow the computer moves to his room. Should be loads of excitement then too.
