Chip off a corner of the Scantron sheet (ensure correct orientation), then, for the visually impaired, distribute a plastic mask/stencil along with the sheet. On that mask, include the candidate names in braille, each next to a hole through which you can directly write onto the sheet.
Such masks are easily available with holes for each line (instead of small holes and braille). Adapting them is trivial. If cost is an issue, replace the candidate name on the stencil with numbers, throw in an instruction sheet in braille with the name and number of each candidate and you can reuse the stencil.
Write-ins are slightly more complicated if the voter is unable to write by hand. But at that point, expecting a trusted person to help doesn't seem too over-boarding to me.

Many (older) phones have a connector for external antennas. Get four that do plus two matching antennas, set up with a couple of yards of clearance from the control hive and get a better result. Repeat for ten sets of hives or so and it'll start to get real interesting.

In most of the western world, prepaid SIMs have only been sold to users with some sort of proper ID for a couple of years now. I'm fairly sure this is mandated through the whole EU. Most countries even have some sort of nationwide identification cards, which tend to be the single or one of very few ways to, well, prove your identity.

Opera Mini (5 beta, available from the market) can make use of Opera Link, keeping bookmarks and co. in sync through all desktop and mobile instances configured for the same user.

In addition to what Fx and Fx Home do, it also includes a fast rendering engine, better UI, snappier JavaScript, a better developer console, an awesomer bar and a bunch of other stuff. With alternatives like Chrome and Opera, when can we finally put that XULly abomination to rest?

how can a webserver know what fonts are installed?

JavaScript. Detects screen resolution and plugins, too.

That's just the User-Agent string. The actual fingerprint consists of that and a big bunch of other headers your browser sends out with each request. Language, preferred encoding, plugins; screen resolution, your installed fonts and so on.Changing your standard browser's user-agent to something like you quoted above is a surefire way to be even more unique.
Check the panopticlick page for your details. Keep in mind their "bits of identifying information" only apply to a single header. A bit of work and identifying over all of these fields is easily done. Throw in a bit of extra work and users can be singled out even after they change one or two of 'em.
Summing all the lines together, I can get some 70 bits of identifying info out of my (almost worst-case) setup: Ubuntu 9.10 running a snapshot of Opera 10.54 with a couple of extra fonts and a weird screen resolution.Cut away user-agent and plugins and we're still at some 35, more than IPv4 addresses out there.

Some time ago, there was a university experiment combining a high-resolution (centered) display with a large-surface but low-res projection, for peripheral vision. Never heard of it again, so apparently it wasn't that successful. IIRC, the high-res part was fixed, though.
Small 1080p displays should be available, there's plenty of LCD projectors. Possibly not in an inch, probably not too cheap.

Actually, one of these plus a 20" portrait (1200x1600) screen to it's left and right is a fair bit more awesome than just the 30" display. Since, if you're doing that, you probably run two video cards anyways: throw in a 1080p projector, just in case of wanting to watch a movie in bed or something. Ten million pixels. Fun!

Working fine here. Synology appliance with an extension unit connected through eSATA. SMART is working fine for all disks in the extension and base units.

The theoretical limit of a DS1010+ and a DX510 (which is the only Synology offering in the 20 TB range) is actually 16 TB due to them using ext3. With 2 TB drives the best you can actually get are 14.5 TB with RAID-6 or RAID-5+Hotspare. Spanning a RAID-5 over all disks would result in a volume slightly larger than 16 TB, which will not work. I've tried it.
Still, 14.5 TB is pretty much okay in my book. If you actually do need more, build a Backblaze pod (same price league as two DS1010+ with a DX510 ea.; more then double the drives of that) or be spendy and get an X4500 (related as far as the number of drives goes. A completely different class in all other aspects.)
