Real, Real time people use the ARMxR, not ARMxA(Pi) or ARMxM(micro).
Linux is useful in the post MS era.
Keeping the code/data/docs on an external USB stick, means the SD card just holds the OS.
Easy then to swap OS.
It could be fun writing, even if I am a terrible author.
Lots of pictures and code or do what they do these days, YouTube videos.
My kid learns more minecraft tricks from youtube than doing it himself or reading the books..
When you have no money is the time to do it.
Time poor too now, most of my writing is done after midnight, no one up to distract or annoy
Coming to the conclusion that home lighting could be done off grid.
Most suburbanite homes have a fuse for the lighting wiring.
Disconnect the lighting circuit and replace the GU10 fittings for GU5.3 fittings then 12V LED lights with battery back up could be retro fitted to most houses.
Special wall points for 12V powered stuff, like monitors, Pi PC's, NAS.
Mains voltage stuff is not as important as it used to be with the fridge the number one issue as it runs 24/7.
Things like TV are multi voltage and getting more efficient, soon 12V OLED roll up stick on wall?
Not that TV is a big as it used to be with small screens and phone/tablets potentially in every room.
Utilities are a big problem, too expensive for most people to replace.
Cooking and aircon really the major problem we have here.
Peak demand brownouts have even got the politicians talking big project again.
New land releases, first thing to go is the trees and top soil.
Go through a new housing estate and feel the heat (er probably not much for a desert dweller).
When we went looking for a house years ago, we spotted one new MCMansion with 9 Aircons, right next door to another McMansion, three feet from their aircons.
People like my brother used to pay $5000 a quarter before he put in wood fire and solar.
We were complaining about a $300 bill at the time
We ended up getting old hardwood place on a block with the most trees in the street.
No insulation, wood fire and no aircon till this year. Dead trees/branches keep the house warm in winter.
Still need a bit of power for the battery chainsaw
The building regulations are stuffed in this country.
No allowance for thermal mass, super insulation compulsory .....
As a result government has to spend billions for power problem solutions.
Yet there are people who have figured out solutions that get mostly ignored.
None of them think about it from the ground up, all based on "traditional" housing models.
Hence we need people like you to write books an how to do it
