there's a Bitcoin Data Center in Texas where the fans are so loud the residence are having a range of health problems.
Texas does not have zoning laws, so I guess this in by design? Also: https://en.wikipedia.org/wiki/...
I guess your option would be to move to a place with regulations that prevent things like this.
That's not honest, just naive. RAID relies on block devices implementing ECC codes. Checksumming on top of that only make potential sense, not even "far more sense", when you suspect those ECC mechanisms are inadequate. ZFS sells this and you buy into it but that doesn't make it compelling.
tl;dr Bit rot is real, and has happened to me. ZFS protected my data.
I don't really want to call you naive here, but you are way too trusting. ZFS' checksumming has protected me from on-disk bit rot. The sequence went like this:
Week 0: ~16 MB file is written
Week 1: ZFS scrub is run, verifying all checksums are correct.
Week 2: ZFS scrub is run, verifying all checksums are correct.
Week 3: ZFS scrub is run, verifying all checksums are correct.
Week 4: ZFS scrub FAILS, indicating the disk cannot return the correct contents for this file. Subsequent re-scrubs failed as well, so it was not a transient issue with the scrub.
This file was NOT rewritten during that time. The disk was not physically relocated, it just stopped being able to return proper contents for that file, and only that file. It never happened again for any file on that disk for the 5 years I kept using it.
My anecdote is not data, but I do wonder how many people have suffered from this, but were not using a modern file-system that could detect it.
Rather than use the "Request Policy, No Script" combo I switched to uMatrix because it has an awesome matrix UI that really makes sense. I also moved to the uBlock Origin ad blocker as it's lighter on the resource usage.

I'd like to see a source for that. More radiation than a properly functioning nuclear plant, maybe.
[ To copy a post from myself from 2005. ] I find this interesting. It's a little old (1982), but the summary is:
For the year 1982, assuming coal contains uranium and thorium concentrations of 1.3 ppm and 3.2 ppm, respectively, each typical plant released 5.2 tons of uranium (containing 74 pounds of uranium-235) and 12.8 tons of thorium that year. Total U.S. releases in 1982 (from 154 typical plants) amounted to 801 tons of uranium (containing 11,371 pounds of uranium-235) and 1971 tons of thorium. These figures account for only 74% of releases from combustion of coal from all sources. Releases in 1982 from worldwide combustion of 2800 million tons of coal totaled 3640 tons of uranium (containing 51,700 pounds of uranium-235) and 8960 tons of thorium.
And that's just for one year. The projected cumulative stats for year 2040 (100 years of coal burning):
U.S. release (from combustion of 111,716 million tons): Uranium: 145,230 tons (containing 1031 tons of uranium-235) Thorium: 357,491 tons Worldwide release (from combustion of 637,409 million tons): Uranium: 828,632 tons (containing 5883 tons of uranium-235) Thorium: 2,039,709 tons
Personally, I'd rather use nuclear power and know where all the radioactive material is than burn coal and have it dispersed into the atmosphere. Omen
Funny enough, around Davis it is known as "The People's Republic of Davis".
I'd rather have something that is a bit more Mac like. When I compile UNIX stuff on OS X, I configure it with --prefix=/opt/{package_name}. I can then uninstall it by just deleting the package directory and copy it to a new machine by just copying that directory. I'd love to see a simple package manager built around this idea.

I refuse to buy e-Books until the prices come down to lower than paperbacks [snip]. And I'm certainly not going to buy them if they are locked to a device or a certain company's devices.
Baen books from http://www.webscription.net/ satisfy both of your requirements. If you purchase the monthly Webscription pack you get 6 - 8 books for $18 (use to be $15, they just raised the price). The books are completely DRM free, available in multiple formats, and can be downloaded over and over if you change devices which require different formats. Or just download the ePub format and use Calibre (mentioned above) to convert it to any format you need.
If you're not careful, you're going to catch something.
