editI don't think it is metasyntactic as much as the 'memory test pattern' for motorola, ex: here. Srl 04:34, 11 November 2005 (UTC)

Content looks accurate to me. Is there something specific in here that needs fixing, or has it been fixed already? Can we remove the notice? --ssd 01:55, 27 December 2005 (UTC)
redundant
editIsn't this content redundant to mosst of what is at magic number (programming)? -- Mikeblas 23:01, 18 February 2006 (UTC)
It's older than RS/6000

In fact, use of this is older than microprocessors!
In the 1970's, Control Data Corporation introduced a vector supercomputer called the STAR-100. Basically a 64-bit pipelined vector box with virtual memory, system critical crashes under STAR-OS (written mostly by the programmers at Lawrence Livermore Laboratories, but mainted by Control Data) were recorded in memory as "DEAD" codes. DEADBEEF was the code for a fatal paging error (i.e. system code referencing a non-existent page).
There were many other DEAD codes, not all as memorable. DEADCACA, DEADDADA, etc.
I think this may be the first known use of this crash code.

Opinion or fact?
editI think some of the text should be rephrased. "Most numbers, when displayed in hexadecimal, are uninteresting and not eyecatching" depicts someone's opinion, not a fact. It's fine on a blog, but IMHO it's out of place in an encyclopedia.
Another text might need some refinement: "Since it is unlikely that 32-bits integers take this specific value". That's only true given a certain chance distribution of the possible values. On average, just looking at the amount of data stored, every other 8 GB DVD has 0xDEADBEEF stored in one of its 32-bit words.
merge
editI think this article should be merged to Hexspeak. The content about magic numbers can be merged to Magic number (programming), which Hexspeak already links to. —Quarl (talk) 2006-12-16 08:20Z
