Packed!

Packed! is the fifth album by rock group The Pretenders, released in 1990. For this album, the only real member of the group is Chrissie Hynde; no other person is pictured anywhere within the album package, and a rotating cast of session musicians (rather than a set band) is used to back Hynde throughout, essentially making this a de-facto solo album by Hynde, only using the Pretenders name to satisfy contractual obligations. However, drummer Blair Cunningham plays on all tracks, though he is not credited as part of the band.

Data structure alignment

Data structure alignment is the way data is arranged and accessed in computer memory. It consists of two separate but related issues: data alignment and data structure padding. When a modern computer reads from or writes to a memory address, it will do this in word sized chunks (e.g. 4 byte chunks on a 32-bit system) or larger. Data alignment means putting the data at a memory address equal to some multiple of the word size, which increases the system's performance due to the way the CPU handles memory. To align the data, it may be necessary to insert some meaningless bytes between the end of the last data structure and the start of the next, which is data structure padding.

For example, when the computer's word size is 4 bytes (a byte means 8 bits on most machines, but could be different on some systems), the data to be read should be at a memory address which is some multiple of 4. When this is not the case, e.g. the data starts at address 14 instead of 16, then the computer has to read two or more 4 byte chunks and do some calculation before the requested data has been read, or it may generate an alignment fault. Even though the previous data structure end is at address 13, the next data structure should start at address 16. Two padding bytes are inserted between the two data structures at addresses 14 and 15 to align the next data structure at address 16.
