know your geography

In Uncategorized on November 22, 2002

if there was any space left on the page it’d be easy to subtitle the national geographic-roper 2002 global geographic literacy survey
(enough of a mouthful by itself i think) as “ooh, look at those dumb americans”
but i’m sorry to say that britons do just about as badly. i do have to wonder
what rock the 42% of young americans who couldn’t figure out that the taliban
and al qaeda were based in afghanistan have been hiding under. at least
only 16% of young britons didn’t know that.

i agree with kevan
that an abstract notion of geography is good enough for most purposes and
there are a few countries in the survey that i wouldn’t have pinpointed correctly
if i hadn’t have had a limited number of choices to choose between (i imagine
the original survey takers had to pick off the whole map). as is usual with
any survey i have complaints about the results and want more information.
so 80% of americans don’t know which country iraq is in, we’ve no way of
knowing how many of them knew more or less where it was but couldn’t pinpoint
the exact right bit of land.

another complaint is with the conclusion that

Americans who reported that they accessed the Internet within the last 30 days scored 65 percent higher than those who did not.

as i would expect to find that this has more to do with the education
levels of people who use the internet than the internet itself. though to
be fair to national geographic they don’t start screaming that this means
the internet makes you brighter as lesser publications might.

my overall feeling from the bits of the survey i saw was that sweden
and canada had the most geographically literate populations but the conclusions
say that canada did badly and that germans and italians were up there with
the swedes.

the bit that’s really thrown me is wondering what the cultural differences
are that make mexican’s really bad at figuring out which way is west!

all squished up

i looked at gzip compressing webpages aeons back (that’s zipping pages
up on the server and sending smaller files to the user who’s browser then
unzips them with the user noticing no difference apart from faster downloads)
and all i remember is that it seemed too complicated at the time. either
i was completely wrong or the world has become much simpler. if you’re writing
php pages stick this

<?php  ob_start("ob_gzhandler");?>

at the top of your pages and watch your bandwidth tumble. you can check if your pages are already gzipped using leknor.com’s checker. loquax’s bandwidth is now looking so 1999. joy. if our isp had ever actually charged us for excess bandwidth i’d have discovered this trick a long time ago.
