It's a promising development for the media dongle that's already made such a big splash, but XDA Developers reports that there isn't a lot you can actually do with a rooted Chromecast yet . Still, the tinkering can begin.
A survey from the American Customer Satisfaction Index shows the Galaxy S3 and Galaxy Note 2 both outperforming the iPhone 5, 4S and 4 among U.S. consumers by two to three points on a 100-point scale.
Interestingly, however, consumers in Samsung's home territory of South Korea actually preferred the iPhone 5 to the Galaxy S3, the researchers noted. Familiarity breeding a little contempt?
Finally, we go back to AnandTech for the revelation that Android 4.3 includes support for TRIM, a feature that cleans up blocks of data on solid-state storage after they've been deleted.
Brian Klug explains that, since solid-state storage never actually deletes anything through software, "deleted" files are simply unindexed, but still present.
"Let's say you copy a 3GB movie to your internal storage, watch the movie and later delete it. You'd have 3GB free to re-use, but until you re-write those blocks the eMMC controller would treat all 3GB as valid data. There's a data structure used by the eMMC controller that tracks mapping logical locations to physical locations in NAND. I won't go into great detail here but the more complex that mapping becomes, and the more locations that have to be tracked, the slower internal NAND management works," he wrote.
Clearing the disk I/O bottleneck caused by un-TRIMmed data should extend the performance life of many old devices. Here's hoping that saves at least a few people some money down the road.
