Charles de Gaulle retro real time traffic map

Charles de Gaulle retro real time traffic map

real time retro traffic board in charles de gaulle

This photo was taking in the arrivals hall. Like everything else at Charles de Gaulle terminal 1, it was incredibly futuristic 40 years ago. It’s a real time traffic map, with congestion on the major Paris roadways indicated with small red lights, like a more useful lite brite. Collecting, synthesising, and visualising the world in public space .. beautiful. What we could do with a plasma screen, network, and some real estate at Heathrow …

Oxford Street

oxfordstreet
My friend Edward Wilson took this scanned photo from top of a bus heading down Oxford Street. See the completely black cloaked figure in the center — it wasn’t there when Edward took the photo.

None of the other photos on this roll had any defects. The flat black area looks unmistakingly human .. though I’m unsure if the size and orientation of the figure is completely consistent.

The strange thing is how the figure is centered and not overlapping any other objects in the scene. It really looks like someone was crossing there.

Any experts on paranormal photography out there, with opinions on this photo? Email edwood83 yahoo com

Will be leaving for Paris any minute, for Les Blogs. Should be able to find my way around. If you’re going, hope to meet you there!

the World as a Blog

Two years ago World as a Blog was let out onto the net. Geography has since infiltrated a big part of my life and thoughts. That’s pretty obvious from everything else written here.

Greasemonkey UserScript: Bloglines article hider

Greasemonkey UserScript: Bloglines article hider

I’m subscribed to a number of high traffic discussion lists in bloglines (including the greasemonkey developer list ;). It’s great because this stuff doesn’t clog up my mailboxes. But in bloglines, the entire email is displayed when scrolling through; I’d rather just skim Subject lines like in email.

Here’s bloglines-hidearticles.user.js, greasemonkey user script. It adds a show/hide articles toggle to all articles, and to each individual article. Works for any type of subscription (not just email) in bloglines.

myRadio weather nuggets are busted

myRadio weather nuggets are busted

Like I said in the previous entry, I have a problem letting old projects die. But in the case of the myRadio weather nuggets, I don’t have time right now to fix it.

Kevin Respecki alerted me to the problem. The SOAP service providing data for the weather nugget/module has been disabled by xmethods.net. Browsing xmethods, I found another SOAP service for weather by zip code which seems to be functional.

I can’t remember how to specify a SOAP service to Radio Userland. If any enterprising RU hacker wants to take a look, the SOAP request parameters are specified in table myRadioMyRadio.modules.weather.webservice.

There are still some good ideas in myRadio, which haven’t been completely realized .. enabling users to aggregate and publish personalized web services, through simple template controls. A couple years on from any active myRadio development, most interesting web services are RESTful or RSS.

Update to GMaps Annotation User Script

Update to GMaps Annotation User Script

I’ve updated the user script described here and here.

The old user script has ceased to work (and may have delivered you here). The old script used “script injection”, which is now old fashioned with Greasemonkey providing xmlhttp requests to any domain.

It still doesn’t work perfectly .. for some reason the map does not recenter and zoom to the location specified in the points file. It could be some change in the XML format, or the gmaps javascript. No time to track this down now, and I know this kind of thing will continue to plague gmaps hacks. If you’re inspired and figure out the problem, I’m happy to hear about it and update the script.

Yea, I have a problem with allowing old projects to die.

Special thanks to “Some Guy” for motivating me 😉

the SuperShuttle Ghost of NYC

the SuperShuttle Ghost of NYC

ny

The Google Ridefinder is basically an shiny, but useless, advertisement for some taxi and airport shuttles. Now public transit would be another thing…

The intriguing thing for me is that Google has a source of semi-precise, semi-current information on the location of all these vehicles. The GPS traces of SuperShuttle run over the surface transport infrastructure, and in time the traces could reveal the streets. Like some of the plans for OpenStreetMap.

Peaking at the javascript, the ridefinder data source is here. Started pulling down the XML for NYC every 5 minutes (the minimum update interval for ridefinder) and gathered about 1500 files over the past 5 days. Approximately 25-40 vehicles listed at any point, so at least 40,000 coordinates. The feed does not individually identify each vehicle, so it would be tricky to try and trace points together based on proximity and trajectory. And at five minute granularity, tracks would cross corners, connect over tunnels, etc.

The resulting plot is posted above, and in original size. The outline of Manhattan is clear, with Central Park obvious. The avenues and Broadway are somewhat distinguished, and possibly extractable as the lines of highest density. Bridges are visible, as well as backup at the tunnel entrances. Ant like tracks to the airports are prominant. Strange anamolous high density points dot across Queens .. are these parking lots for unhired vehicles or coffee break spots?

Could see this data visualized, analysed in a number of ways. Time lapse revelation on the NYC ghost. Perhaps other airport shuttles would study the movements of SuperShuttle to gain a competitive edge.
