One dependent champaign of mystery, inwards Blogger lore, concerns the infamous "bX" codes.
One forum personality, long ago, compiled a spider web log listing several hundred known codes, in addition to their supposed "diagnoses" - in addition to would afterwards purpose the spider web log every bit a reference, when advising how to solve a given "bX problem". That same individual showed consummate lack of understanding, inwards a unmarried sentence.
In many cases, a "bX" code is exactly a illustration of a Blogger Engineer trying to empathise why 1 department of code is now, magically, causing approximately other department of code to popular off active.
One of the near intriguing arrangement problems, that I always worked on, long ago, involved a infirmary medical ordering arrangement - in addition to a MD from Eastern Europe, who instinctively typed a "," when a "." was needed, when he was ordering medications for patients. Computer processes are real syntax sensitive - in addition to a figurer arrangement that uses "," to kind out sections of information from other sections of data, is going to receive got a work amongst an unexpected ",", where a "." is expected.
To diagnose the problem, I had to popular off along the entire arrangement (for a 1,000 bed hospital) offline for an hour, piece I scanned the "console log", graphic symbol past times character, analysing the transaction that caused the problem. Discovering the campaign of the work required identifying this 1 doctor, lately arrived from Eastern Europe - in addition to an obscure detail, knowing that people inwards Eastern Europe write numbers amongst "," in addition to "." interchanged.
Blogger code is real complex, past times necessity - from having to back upward people using different browsers amongst out of engagement versions - to having to back upward people who "confuse" syntactically essential "." in addition to "," characters, in addition to may write dates differently. And, Blogger code is inwards purpose on a lx x lx x 24 x vii x 56 basis.
There is non 1 instant inwards a 24 hr day, of a 365 (or 366) hateful solar daytime year, that the Blogger service could always locomote taken offline, worldwide, to diagnose 1 unmarried "bX" related problem - permit lone an entire hour, every bit was how the unexpected "," was diagnosed, in addition to thence long ago.
That beingness the case, diagnosis of many Blogger problems starts amongst a real distributed in addition to structured "console log", in addition to "bX" diagnostic details. And that is all that many "bX" codes are - structured indexes into the Blogger code base, which are referenced past times entries inwards the diagnostic logs.
There is no magic or mystery here, really. Just touchstone information technology manufacture practice.
