UPS batteries usually don't last more than two or three years. Test on a regular basis, or just buy new batteries every two years.
Heat kills UPS batteries. A lot of UPS's connected to desktop PC's are sitting on a carpeted floor under the desk. That carpet makes wonderful insulation that helps keep the batteries nice and warm. Put the UPS somewhere that has good airflow all around the UPS's case. I simply laid a couple large pens under either end of the UPS to get it an inch or so off the carpet, and that works fine.
EGNOS is the EU's equivalent of the FAA's WAAS. EGNOS and WAAS are systems that supplement GPS by providing corrections (thus giving higher accuracy) and integrity monitoring, so a GPS receiver will be informed if a GPS satellite is outputting bad data.
EGNOS is only available in Europe at the moment because it's only being transmitted from one geostationary satellite that's sitting over Europe. WAAS is currently being transmitted from two geostationary satellites over the Americas.
Neither system is what I'd call new - they've been in a sort of beta test phase for years, and there are already consumer receivers on the market that support EGNOS/WAAS.
I think 8-bit processors like the 6502 aren't the greatest learning tools because the instruction sets are somewhat limited and full of idiosyncrasies that will make inexperienced programmers pull out their hair. I'd go for a 16-bit or 32-bit processor with a nice clean instruction set, e.g. 68000, PDP-11, VAX. There are probably newer processors that fit that description too, but I haven't done any serious assembly programming in 10 years.
I'd also go for a very simple computer to start with, something with very few peripherals and a very simple (or no) OS - something that will let you get at the guts of the hardware and get experience manipulating peripherals, doing hardware-level I/O, writing interrupt handlers, etc.

Having said that, Eclipse is pretty good, and much more pleasant to use than NetBeans.

Kim Cattrall with red hair, and lots of shooting and fighting and magic. Great movie!

Which doesn't change anything, because Java in general is unsuitable for high-performance scientific programming.
Hardly a sneak peak - Garmin has had that product info page online for weeks (months?).
