Who trained Palpatine?

I’ve colored the Jedi according to dark side/light side affiliation, except Yoda.

Adobe is buying Macromedia. Here’s one possibility for how their services could fit together to create a very interesting end-to-end web workflow. This could possibly be what I’ve been waiting for from Adobe for years - the ability to do web-based structured content editing for print and web publications in the same interface.

RAID (redundant array of inexpensive disks) is a series of disk configurations to get more reliability or performance (or both) out of multiple disks. RAID typically consists of two operations - striping and mirroring. Striping involves writing disk blocks in a pattern across multiple drives. This is very fast, because modern controllers can read and write to multiple disks simultaneously, so you essentially double your disk throughput. But you also double your liability, because a failure on either disk causes data to be lost. Mirroring takes care of that by writing exact copies of the same data to multiple disks. RAID-5 is a combination of the two, and is the most common, balancing space efficiency with speed.

Here are a few common configurations. All of these can be extended to larger configurations of more drives.

Each cell tower is a short range transceiver (sometimes disguised as a tree). Usually, if the density is high enough, you’re within range of multiple towers, and when they move, they hand off your signal to the next one. Each of the towers is individually wired to the cell provider’s internal network, which is bridged to the standard phone system.
