Is that plugged to a UPS or is your power just that stable?
- burntsushi 4y ago
  I get lots of outages. At least one a year that is 8+ hours. It's plugged into a UPS and I have a whole home standby generator.

I'm more impressed you didn't get a single power cut in that time.
- burntsushi 4y ago
  Oh I have. We get power outages all the time where I live. At least a few a year that last 8+ hours. Have even had some multi-day outages. I have all my machines plugged into UPSes and we have a standby whole home generator. So the only way any of my machines shut down is if I do it explicitly.

Coming from the author of ripgrep, which is a tool I use daily, I've got to say it's an honor to see you answering my silly comment! Office at home certainly beats datacenter hosted but by 5x? Not sure... ; )

  Hah. The only way it's possible where I live is with a UPS combined with a whole home standby generator. (I got the generator not just for uptimes haha. Got it because we get a lot of outages and we were losing a lot of spoiled goods from our fridge. About half our neighborhood has generators of some kind.)

    refrigerators don't really use much power while running. As a joke-y test i ran my refrigerator off of my truck via an inverter connected to the battery terminals and 3 50' extension cords. I think a fridge draws less than a decent GPU while running. You do, however, need a decent inverter to start the compressor running in the fridge, though. Also, a deep freeze that is the top loading style is best for preventing spoilage, especially if you keep all the available space full of bags or bottles of water. I also have a makeshift "whole home" backup generator, 11.5kW/9.5kW peak on gas/propane, but only because i have a well, and the pump draws something like 4.5kW when running. The extra headroom allows me to run my 5 ton HVAC and have running water and lights and everything.

      Yeah, our fridge has a top loading freezer. I think that stuff spoiled once during a particularly long outage. We do also have an upright freezer. We purchased that after getting the generator, so the advantage of it keeping stuff frozen longer was less important to us than the convenience of easier access. (And we were okay to sacrifice a bit on capacity too.) We also have a hot tub and we're in New England. We were worried about a multi-day outage resulting in the tub freezing in the winter. A low probability event, but one that was conceivable. Both the fridge and the hot tub problems can indeed be resolved with something less than our 16kW generac. The hot tub really just needs a small space heater to be put inside the cabinet to prevent the pipes from freezing. And as you say, fridges don't use much power. So powering those two things (and our upright freezer) would need a pretty small power source. So absolutely, we overdid it a little. But it's super nice having it kick on when we get an outage. Otherwise I'll be playing the, "is it really worth going out in the snow, lugging out a generator and getting it running if the outage is just an hour?" game. There's also the issue of maintenance, which I'm... not greatest at to be honest. (I have a 2 year old at home and time is just absolutely slipping by. It's hard enough to keep up with normal chores.) The standby generator does a weekly test, so we know whether it's actually working or not. Yeah, definitely a bit of a luxury, but worth it for us. :-)

Don't you need to reboot after kernel updates?
- burntsushi 4y ago
  This particular machine is a mac mini. Otherwise, I have a lot of machines. I just don't get around to updating and rebooting them that often. I very rarely use the mac mini. Basically just for testing. So at some point, it got to a crazy uptime and now I'm purposely trying to see how long I can go haha. In theory the battery in UPS will eventually need to be replaced. Otherwise I don't see it ever losing power given that I have a generator
