meaning of postcardware
1. postcardware Shareware that borders on freeware, in that the author requests only that satisfied users send a postcard of their home town or something. This practice, silly as it might seem, serves to remind users that they are otherwise getting something for nothing, and may also be psychologically related to real estate "sales" in which $1 changes hands just to keep the transaction from being a gift. [Jargon File] posted write-through A cache with a posted write-through policy e. g. Intel 80386 delays the write-back to main memory until the bus is not in use.
