Alt: Saturday is game night.

that is a perfect way to give people information (those guys who bug incessantly) without actually giving them any.

I imagine this would be funnier if I knew precisely what Hashing was.

I'm not quite sure if I get this one. Is it describing a method for choosing a pseudo-random location?

Anyone care to dumb it down?

The coordinates he created in the comic (for the SF Bay Area) are for Tennessee Valley in Marin County which is actually a really nice area. Unfortunately it's halfway up a ridge in scrub brush if anyone wants to find it. http://maps.google.com/maps?f=q&hl=en&geocode=&q=37.857713,+-122.544544&ie=UTF8&ll=37.86076,-122.536097&spn=0.031917,0.079651&t=h&z=14&iwloc=addr

therocket:
It takes the general position of where you are, and then takes random numbers (generated from DOW opening price from a certain day) as the specific part. So, if used in a populated area, it will give you something around where you actually are.

BTW: I checked both the original and generated locations. Did not find anything of interest.

Shouldn't this be in the "meetups" boards?

Oh, and I cannot attend, sorry, other side of the country, I don't think I could even get a flight out there this close to Memorialgame Day weekend if I could attend.

I did it with my location and yesterday's date, and got a car park in Yamato.

It's fairly pointless since my timezone is GMT+9. The Dow Jones opens at 9:30 EDT, so that corresponds to 22:30 local time. So I can't get today's coordinates until an hour and a half before today ends.

If this also gave a convenient time, I'd probably check out the location from time to time.

I decided to move the map over to the East Coast, and came across this. I'm trying to access the map again for a better screencap, but am currently phailing.

Today's a bust for my area:

Problem #1: Located in the middle of a military base

Problem #2: Said military base is 75% swamp land

I'd imagine most of the coordinates that this spits out will either be very tough or impossible to get to...but hey, that just makes it more interesting doesn't it, maybe your perfect geeky soulmate is sneaking in now through miles of messy swamps. Waiting for you.

Anyone want to join me about 4 miles offshore? No? Maybe not tonight then. Also too bad we can't use this algorithm for dates in the future so we can't plan a location in advance, although I guess that's sort of the point.

I am intensely disappointed that this comic contained coordinates, yet did not specify the location for the next meetup.

Saturday and Sunday you get at least a day or two notice, as you are using Friday morning's Dow opening.

I'll assume the title of the comic is a reference to geocaching, am I correct? That should help out the over-my-head people a bit, although I'm a bit baffled by the Dow numbers myself.

No no. I checked one for my current location, and one for where I live. The route I travel to work crosses a degree of longitute, hence I can get 2 locations.

We do have a location for the next meet-up. Unfortunately, I'm on the opposite coast..

I'm offshore as well, in the La Jolla/San Diego area. I think it'll be good training if any of us want to be an IronMan triathlete...

My location is in Nellis Air Force Base. Maybe not. :)

But then, travelling to a random location in the deserts of southern Nevada is probably not the most interesting thing in the world. Next time I'm visiting northern California I might give it a shot, the degree-square surrounding Santa Rosa looks mostly accessible and very nice.

Unless I misunderstand, the meetups are Saturday at 4, so you wouldn't know where to go until the Dow opens Friday morning (then you'd plug it and 2008-5-24 in)

Is the opening price for the DJIA the same as the closing price for the day before? Or does it change between close and open?
