It's the most important component. More important than even security and communications modules.
If we have the permaculture in a closet debugged and included as a module in the first release on Github of CD-OS, our software is going to be the bomb in the survivalist/prepper community.
Still nervous about eating the fish. They are worth their weight just for the nitrates they produce for the plants. I am still deliberating - do I want goldfish in the internal tank sheerly for their value as fertilizers or do I want silver perch? Tilapia are illegal in Australia (of course.) They are the perfect fish for aquaculture ... because they are ugly bastards with faces nobody could anthropomorphize. If I raise the silver perch I think I am likely to get too attached to them. If I raise the goldfish with no intention of eating them, I think I'd feel a lot better during the conclusion of the test duration. Goldfish live for many years and would be worth their minimal feed just to produce the nutrient solution for the plants. I could always take the goldfish back to the pet store if I feel they are getting too big for the tank.
This is also the test case I am using to debug the Lua scripted modbus service, which afterwards will be fit to control anything else you want to attach to CD-OS and monitor in an HMI SCADA setting. I am taking pains to even make the manifest editors and tools very flexible and easy to set up.
