Manually fixing bit flips in BTRFS

Somehow my BTRFS file system became corrupted by what appears to be a single bit flip in a metadata field. Rather than copying all the data and reformatting the file system, which would have required another disk at least as large as the original, I decided to try to fix this manually, which appears to have worked. I've documented the procedure I've used here, in case I need it again or someone else runs into a similar issue and finds it useful.

The first thing you should do is run btrfs check. For me this produced the following output:

Opening filesystem to check...
Checking filesystem on /dev/nvme0n1p1
UUID: ec7afe1c-8478-450a-82fc-d17b32d8ca3d

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Prepare for Ruby 2.0, today

Ruby 2.0 is around the corner, estimated to be launch February 2013, for its 20th anniversary!

Wouldn't be great to be able to test Ruby 2.0 features and report possible bugs?

Things like Refinements, built-in ANSI coloring for Windows or even better, faster startup

Users of other OS like Linux and OSX already can install upcoming versions of RUby thanks to RVM and rbenv tools, but what about Windows?
