How does dropping flash for HTML5 remove an attack vector? It just replace one attack vector with another.
Do you really want your OS taking on the overhead of RAID? Desktop motherboards with hardware RAID 0/1/0+1 are easy to find and cheap.
The motherboards you are thinking of actually do the RAID in software through a driver. I've been running 4 drives in RAID 5 with Linux's software RAID for a a few years now, and never had an issue. Even the parity calculations are trivial for a modern CPU, and if you're just doing RAID 0/1 the overhead is even lower. I even see software RAID being used in a lot of servers these days, although hardware RAID often has some benefits in terms of hot-swap, etc.
I'm not sure how easy RAID is to configure from a GUI in Ubuntu, but I believe the Fedora installer can do it, and probably others. Or if you know your way around a Linux system its fairly trivial from the command line.
If it is the person who wrote the check, there is still an image of the check.
Right, but the person who wrote the check is claiming the image is faked. They can intentionally not keep a carbon copy, or better yet just make sure the last 0 doesn't go on the carbon copy. The only evidence the bank has of a check for $1,000 is an easily faked image submitted by the customer. Everything else says it was a check for $100.
Of course the same thing applies to a real check...
