Rather than using a backlight as on LCD-based tablets, the Paperwhite uses a transparent light guide that directs light from four edge-mounted LEDs down toward the surface of the display.

"Objective-C on its way to become "language of the year" again
... year 2012. Objective-C continues to rise. Other mobile phone application languages such as C, C++ and Java are rising too but not fast enough to compete seriously with Objective-C. In fact it seems that if you are not in the mobile phone market you are losing ground."
So it appears that Objective-C is twice more popular than C#...
Who is using C that much now? Maybe those who do need big help from search?
Results are is in part result of method of measuring, based on search engines statistics...

Windows 8 "File History" Backup (aka Time Machine for Windows)
How to Use Windows 8's New File History Backup (aka Time Machine for Windows)
"Windows 8 comes with a brand-new backup feature called File History, that works similar to Apple's Time Machine: It automatically backs up files in the background and lets you restore them from a simple, time-based interface."
It is not as "fancy looking" as Mac's "Time Machine", but it does similar job.

Data Access Speed: HDD vs RAM
In this interview it was mentioned that
sequential reading from HDD could be faster than random access to memory.
YOW! 2012: Marko Rodriguez - Graph Systems and Databases | Going Deep | Channel 9:
Gremlin graph traversal language
"Write-Only" data systems have advantage of sequential access to data.
One of such system, Datomic, keeps creating index blocks for fast access,
but original data are write-only.
In similar way, Google's Big Table keeps creating indexes for fast access to subsets of data...

The claim about data access speed is interesting, may be worth checking.
