Today we had our last Pathfinder meeting of the year. Attendance was a down because one of my families had their annual Christmas gathering today (that took out three kids plus a counselor). But we still had a good time.
We worked on the Computer honor, but only got through the first requirement. I used to design computers (before I switch to writing software for them), so they are not much of a mystery to me. It’s difficult to understand what others don’t understand. Asking questions helps a lot.
Although it’s not required, I explained how the binary numbering system works. It seems impossible that a computer can store any (rational) number as a string of ones and zeros, but once you understand the mechanism, it’s pretty cool. I think they all came away with that today. I lined four kids up to form a half-byte. Each kid represented a binary digit (aka, a bit), and they could be a one or a zero, as indicated by a raised or lowered fist. Then I taught them to count.
I brought an old PC in with me and we opened it up and took a look inside. I pointed out and explained the function of the CPU, RAM, hard drive, CD-Rom drive, and mother board.
When the meeting was over, I had to hang around for two more hours so people could pick up their fruit orders. I borrowed Ken’s truck on Friday and drove to Keene to pick up 60 cases. That’s a two-hour drive each way, and it pretty much took out the whole day. The fruit arrived at 11:00, so I had to leave here around 9:00. We got it to the church and finished unloading it around 2:00. No point in going back to the office after that.
That’s about as boring a post as I think I have ever written, and that’s after a week of things to choose from. I did have a pretty intense week at work, but I try to avoid writing about that. I think it did factor into the shortage of writing material though – I was just too tired after I got home to do anything, and unless I do something, there’s not much to write about.

Thanks Celi. Binary does indeed mean two somethings – ones and zeros. That is the foundation of all things digital.

I don’t think your post was boring, but then I don’t think computer guts are boring. My first, back in the 80s, was an old IBM with a 20 MEG hard drive, a 5-1/4 floppy drive, and Dos for an O.S. that you could play pong on. I look at how they have evolved in such a short time and am simply amazed!

Sounds pretty similar to my first IBM-compatible PC. It was 12MHz ‘286, with half a meg of RAM and a 32M hard drive. Monochrome monitor, and no mouse.

Sometimes life gets a bit busy and takes a byte out of our free time. A new language and numbering system adds to the fact folks linger about taking on computerese. Good that you take some mystery out of it for the kids. Your hectic work schedule will make one appreciate a few days during the holiday when you can think on something else. Have a great week.

Thanks Grampy. When we got home my daughter asked me to open up the PC we looked at during the meeting. She drew pictures of its innards and made a vocabulary sheet. I guess she was interested!
