  • If you make it to Medicare age, it gets a lot less stressful. eg: my folks have had 4 knees replaced with very little out-of-pocket cost. There’s still supplemental insurance, but Medicare, not the profit-driven insurance company, determines what gets covered, and they mostly listen to doctors. There’s always edge cases, where some treatment might not be covered, but I feel like those are uncommon.

    One way or the other, my ultimate health care plan is 9mm.










  • That’s my point: fusion is just another heat source for making steam, and with these experimental reactors, they can’t be sure how much or for how long they will generate heat. Probably not even sure what a good geometry for transferring energy from the reaction mass to the water. You can’t build a turbine for a system that’s only going to run 20 minutes every three years, and you can’t replace that turbine just because the next test will have ten times the output.

    I mean, you could, but it would be stupid.



  • Solar is definitely not a panacea. Near as I can tell, no ‘green’ alternative is - they really depend on making use of local conditions and resources in ways that are not compatible with late-stage production-line capitalism.

    In my area (US southeast), between weather and tilt-of-earth, the solar models predict about half as much annual energy as an identical installation in California or Arizona. Tack on that our electric rate is also about half California, and rooftop solar is a pretty iffy proposal.

    Wind might be better here, if there were any residential/suburban options. Hydro, if you happen to live on a stream. Basically, the useful local resources all require massive scale to utilize, and nobody wants to do that when gas is cheap.


  • I’ve always understood 2 as 2 physically different media - i.e., copies in different folders or partitions of the same disk is not enough to protect against failure of that disk, but a copy on a different disk does. Ideally 2 physically different systems, so failure/fire in the primary system won’t corrupt/damage the backup.

    Used to be that HDDs were expensive and using them as backup media would have been economically crazy, so most systems evolved backup media to be slower and cheaper. The main thing is that having /home/user/critical, /home/user/critical-backup, and /home/user/critical-backup2 satisfies 3 copies, but not 2 media.


  • 3: RAID-1 pair + manual periodic sync to an external HD, roughly monthly. Databases synced to cloud.

    2: external HD is unplugged when not syncing

    1: External HD is a rotating pair, swapped in a bank box, roughly quarterly. Bank box costs $45/year.

    If the RAID crashes, I lose at most a month. If the house burns down, I lose at most 3 months. Ransomware, unless it’s really stealthy, I lose 3 months. If I had ongoing development projects, a month (or 3) would be a lot to lose, and I’d probably switch to weekly syncs and monthly swaps, but for what I actually do - media files, financial and smart-home data, 3 months would not be impossible to recreate.

    All of this works because my system is small enough to fit on one HDD. A 3-2-1 system for tens of TB starts to look a lot like an enterprise system.




  • Trump 45 was happy to let his appointees work as interim this-or-that or acting whatchamacallit, and those people seemed to have exactly as much authority as confirmed appointees. Maybe they didn’t get the full paycheck? but senate confirmation seems to be completely unnecessary to the exercise of power when everyone just goes along anyway.

    I’d be pretty happy to see Dems grind congress to an halt with investigations of absolutely everything, filibusters of everything else, and red card holds, or whatever other magical Senate traditions allow single Senators to completely stifle government activity.
