Exercise for the reader, make a quine that still works even if any one character is mutated (by 1 bit or 8?), rather than deleted.
how about a real native app with instructions? i'd never expect something as high level and wooly as ruby in systems that will be exposed to radiation. that's just asking for failure imo... how robust is the interpreter for instance?
Fascinating exercise. "Deleting one character" seems a phenomenally unlikely outcome of radiation, though.
We had a few similar tasks on CGSE, e.g.
i wonder how far this can be taken... e.g. flipping or setting a random string of bits that would be physically contiguous in hardware as if a real neutron came smashing into the memory... if doing it during run can be achieved etc. how about a real native app with instructions? i'd never expect something as high level and wooly as ruby in systems that will be exposed to radiation. that's just asking for failure imo.…
So yeah, even if you don't go into space or inside a nuclear reactor software can be written to tolerate a lot of harware failures.

Chinese would also drop the verb in this case, so I'm assuming they might do that in Japanese as well.

Japanese is Subject-Object-Verb order, so it was probably "My Ruby (is) terrible". But I don't know Japanese so I can't tell you for sure. Chinese would also drop the verb in this case, so I'm assuming they might do that in Japanese as well.

That definitely wouldn't work with this strategy (two copies), because you wouldn't be able to tell which copy was the mutated one. Error-correcting codes to the rescue. :)
