I just got invited to a meeting for a time zone that doesn’t exist this time of year. In the US EST does not stand for Eastern time, it stands for Eastern Standard Time (~November-~March), EST is not an active time zone, it is EDT Eastern Daylight Time. Its a pointless thing, most people probably don’t notice, but its wrong.
Fake internet points to anyone who knows why DB-9 bothers me.
Edit: corrected a missing n in an eastern
Because the connector you think of as DB-9 is ackschually a DE-9 connector. A DB-9 connector would somehow be the width of those 25-pin parallel port connectors, but holding only 9 pins.
D is for D-subminiature
Second letter is the connector housing size (A through E)
The number is the amount of pins.
ackschually a DB-9 connector has no meaning as low and high density pin counts are specified for the d-sub series, and db-9 is an impossible combination.
