Since computation equals dodopaddle (er "smart phone") for most of My Fellow Americans, I suspect desktops with UPS support will eventually become hard to find. ---- I bought my most recent UPS from a Craigslist seller ... and replaced the batteries with SLAs from Interstate All Battery Center. A Craigslist purchase trip is a chance to visit neighborhoods I haven't seen before. One of my long term goals is to play with a Tesla Powerwall. I hope the batteries in those are better tended and last longer than the batteries in a UPS. Perhaps they will all fail after Musk absconds to Mars with our warranty money. ---- A nearer term goal is to replace all the hard drives in the house with Samsung terabyte SSDs. My test machines suspend to SSD in less than two seconds, and reboot in ten. I can imagine a multicore CPU and a Linux kernel that continuously copies checkpoint RAM images to SSD, so that after power resumes, the machine "comes back" to a state resembling what I was working on when the lights went out. In a well-designed suspend environment, I can "suspend my thoughts" until the power comes back - and I am reminded by my computer of what I was doing before the power glitch. I would like a similar reminder process for other interrupts - doorbell, phone calls, potty breaks, and commands from She Who Must Be Obeyed. Indeed, I would like Linux tools that facilitate "timeouts" for exercise, meditation, ordering my desk, whatever keeps me at maximum productivity and happiness. "Human interrupt and resume" is just another neglected aspect of larger processes that are only partly addressed by a UPS. Keith -- Keith Lofstrom [email protected]
