To give just one example, sometime in March of this year, a bug appeared in the Android app that prevents loading of new posts for several minutes after the phone is plugged in to charge. It's now been 7 months, and the bug has not been fixed.
Interestingly, the basis of web encryption does use the term "encipherment" -- the `KeyUsage` field of X.509 certificates has `keyEncipherment` and `dataEncipherment` flags.
When I was diagnosed back in the mid 00s, the tests were:
- A blood test for elevated levels of tTG-IgA antibodies, which are produced by the celiac autoimmune reaction. This has something like a 5% false negative and 10% false positive rate, so it's generally a strong indicator but doesn't totally confirm the diagnosis.
- An EGD/biopsy of the small intestine. The lining of the small intestine is damaged by anti-tTG antibodies in a way that's recognizable under a microscope.
_No_ difference oversells it, IMO -- the fact that the entire OS crashed is what made fixing the bug so arduous, since it required in-person intervention. To be sure, running the code in userspace would still cause unacceptable service interruptions, but the fix could be applied remotely.
