About my name: Bernard is pronounced as in "George Bernard Shaw," although I have no literary talent whatsoever. The syllables are equally stressed, not accented to rhyme with "canard." The American penchant for nicknames normally reduces this to Bernie, although I have never been particularly fond of it. (It doesn’t even save a syllable.) "Foy" is of Irish lineage, not Asian or anything else. Since it is uncommon, many people seem bent on misspelling it Foye, Fox, Foi, Foyt, Fory, or something even worse. (Incredibly, my nickname has been misspelled "Burney" and "Burnie").
