I'm actually using Johnny decimal now, except that I ended up using 100 buckets instead of 10 because some of the categories simply had too many items in them and they would have overflowed or had no room to grow in them otherwise.
It's so nice to have a good system and never doubt where to find something and where to put a new thing.
I switched from our previous mess to Johnny decimal by using a python script that processed a table in an emacs org mode file. The script filled the rows in the table with the file and directory names and I could then assign a category to each file or directory and say what the script should do to them. Then the script showed the outline of my Johnny decimal system so I could check that's what I wanted. This made it easy to play around with possible categories for all my existing stuff until I was satisfied. In the end it copied all the files to their new home.
I use keepass, and I whipped up a quick script to look all the passwords in my keepass file against the hashes in the list. You have to download and unpack the file first.

The port holes will be acrylic windows in a window frame with O-ring seals. The O-ring will be placed on the side facing away from the water such that when the pressure rises on the window, the pressure on the seal rises as well, making it even more water proof. Same idea for the hatch.
I imagine that the first test pilot will be a computer. Submarines are really nicely simple systems, which is why it is possible for a bunch of amateurs to build one.
I am repairing an old analog synthesizer (Siel Kiwi) with a missing CPU and the CPU board in a bad state.
I can't get such a CPU in the right package anymore, so I'm writing an emulator for it which will run on a more modern, much faster MPU. That alone replaces the CPU, RAM, and ROM. The remaining stuff on the board is lots of I/O both analog and digital which I'm planning to replace with something more modern, like a DAC with 32 channels instead of the many chips and opamp sample-hold circuits that are on the original board.

Thanks for creating Johnny Decimal.
