Problem: Another approach to hardware support for database management was ICL's CAFS accelerator, a hardware disk controller with programmable search capabilities. In the long term, these efforts were generally unsuccessful because specialized database machines could not keep pace with the rapid development and progress of general-purpose computers. Thus most database systems nowadays are software systems running on general-purpose hardware, using general-purpose computer data storage. However this idea is still pursued for certain applications by some companies like Netezza and Oracle (Exadata).

Answer: a hardware disk controller with programmable search capabilities

In total, 156 prisoners have been either acquitted, or received pardons or commutations on the basis of possible innocence, between 1973 to 2015. Death penalty opponents often argue that this statistic shows how perilously close states have come to undertaking wrongful executions; proponents point out that the statistic refers only to those exonerated in law, and that the truly innocent may be a smaller number. Statistics likely understate the actual problem of wrongful convictions because once an execution has occurred there is often insufficient motivation and finance to keep a case open, and it becomes unlikely at that point that the miscarriage of justice will ever be exposed.
Who supported this statistic?
A: unanswerable

Context and question: The army has relied heavily on tents to provide the various facilities needed while on deployment. The most common tent uses for the military are as temporary barracks (sleeping quarters), DFAC buildings (dining facilities), forward operating bases (FOBs), after action review (AAR), tactical operations center (TOC), morale, welfare, and recreation (MWR) facilities, and security checkpoints. Furthermore, most of these tents are set up and operated through the support of Natick Soldier Systems Center.
What are DFAC ships used for?
Answer: unanswerable

Question: At the time the store was introduced, purchased audio files used the AAC format with added encryption, based on the FairPlay DRM system. Up to five authorized computers and an unlimited number of iPods could play the files. Burning the files with iTunes as an audio CD, then re-importing would create music files without the DRM. The DRM could also be removed using third-party software. However, in a deal with Apple, EMI began selling DRM-free, higher-quality songs on the iTunes Stores, in a category called "iTunes Plus." While individual songs were made available at a cost of US$1.29, 30 more than the cost of a regular DRM song, entire albums were available for the same price, US$9.99, as DRM encoded albums. On October 17, 2007, Apple lowered the cost of individual iTunes Plus songs to US$0.99 per song, the same as DRM encoded tracks. On January 6, 2009, Apple announced that DRM has been removed from 80% of the music catalog, and that it would be removed from all music by April 2009.
Is there an answer to this question: How many computers were allowed to play files that used the FairPlay DRM system?

Answer: five
