David Mertz The source document for this representation is http://gnosis.cx/publish/mertz/prospect.html. I omitted the reference list, however, since that seemed to emphasize "translated" as the most common word, which seems misleading. However, omitting the reference list does tend to de-emphasize author names, which might be wrong in a different way. But I mostly like the primary emphasis on common (or not-so-common) nouns.

Bennelong Bicyclist You voted electronically on an open-source system, right?
November 2, 2010 at 5:14 pm
David Mertz @Bennelong: Nope, pretty much an old-fashioned paper Australian Ballot. In Los Angeles they use a good system (I'll go find a picture), actually; it's similar to a punch card, but marked with ink rather than punched through. There is a clever guide to show only the holes for the contests on a given page.

After completion of voting, the ballot box has a scanner to verify that there are no voting errors on the card, which is helpful. In fact, Mary Ann today first inadvertently miscast a vote on a proposition, then realized it and marked the opposite as well, thinking that would simply invalidate her vote on that contest. But the scanner was smart enough to recognize the overvote, and declare her ballot invalid (so she needed to do obtain a replacement, which seems like the right thing).

While I doubt that this scanner software at the poll is open source, the paper ballots are retained, and count as the legal ballot. The machine at the polling place does not actually count votes, but only checks for errors.

David Mertz It's surprisingly non-obvious to locate a photograph, but this diagram shows the idea: http://www.lavote.net/VOTER/PDFS/ELECTION_RELATED/02052008_PRINT_AD.pdf
November 2, 2010 at 6:01 pm
Bennelong Bicyclist Scanning ballot papers for errors before they are placed in the ballot is a good idea, although I can see a few practical problems here in Oz: the first is the (very reasonable) tradition that voting is secret, and thus ballot papers need to be folded so that no-one can see how you have voted prior to the ballot paper being stuffed in the ballot box - so private validation scanners would be needed in each voting booth if that tradition was to be preserved; the second is that the Senate ballot papers are very large - the NSW one was over a metre long (and about 25 cm wide) for the last election, with over 80 candidates (and there have been even larger ones in the past) as well as "above the line" group ticket options - scanning that would be physically difficult. All of these problems fade away with electronic voting (and a whole raft of new problems present themselves).

Bennelong Bicyclist Yes, the sets of Internet (I) and Privacy (P) are not disjoint. I \ P is the set of people who receive unwanted attention from marketers. I ∩ P is the set of people who receive unwanted attention from three-letter agencies. P \ I just want attention. BB's armchair revolutionary fantasy is that BB ∈ I ∩ P but the reality is more like BB ∈ P \ I

David Mertz Any more word about Kitty? Even though it was a million years ago when I last saw her, I'm really fond of her.

On my picture, this is so much nicer than the awkward self-held cell phone shot that makes me look terrible. I actually *like* this one, glasses and all (but also my phototgrapher managed to catch a non-grimace, eyes open, etc).

Robb Ecker Lasting until 45 is pretty impressive. Although I never wear them, i started needing glasses about 10 years ago.
September 23, 2009 at 11:19 pm
David Mertz For the doctors and vision-impaired out there, they are pretty mild, distance only (OD-125-25+105;OS-100). However, after I got the distance-only glasses a week ago, and found the out-of-focus near vision very disturbing, the ophthalmologist recommended progressives instead. So these are the 1-day old progressive version. I can tell my brain will need a little while to adjust to the weird varying focus thing, but feel like this will work out.

I don't think I will/can use them for the computer, or even for general reading. It seems too weird to need to tilt my head up and down to read successive lines on the screen in focus (albeit magnified once in focus, which is slightly cool). And fortunately, it's not difficult to do either of those things without the glasses.
September 23, 2009 at 11:42 pm
David Mertz It *is* pretty amazing to read the street signs and the like more clearly and from a further distance than I have been able to for years (although I have no idea exactly ow long). It's like looking through a telescope at the distant things. I must have seen that well when I was young, and had excellent vision. But since the decline was spread over decades, there was never a moment when I noticed something was wrong. Really it was just the fact that many other people I was with could read signs (and other distant objects outdoors) better than I could that started to nag at me.
September 23, 2009 at 11:47 pm
David Mertz Sorry for the verbosity. This was my big adventure over the last week, as friends can guess. :-)

September 24, 2009 at 12:08 am
Robb Ecker Actually, I'm near-sighted, so it works out OK. I really only notice the deficit when I'm tired.
