Slashdot Mirror

There was some discussion recently about the possibility of building an open source photosynth - and creating an 'open voxel space' map of the planet.

Anyone know if there's been any progress on this?

Is there something in social bookmarking that requires things to have periods in the middle of everything? Or is delirious just copying delicious?

The guy that runs del.icio.us just has a thing for domains like that. He also owns burri.to, and a few others along such lines.

Since del.icio.us got popular, people have been in a kind of mad dash to make clever riffs on the name.

I haven't RTFA because letting the entire world know what my bookmarks are, without an option to let the world know what SOME of my bookmarks are doesn't appeal to me.

I know this is a very common feeling, but I have a hard time understanding why. Could someone give some examples of bookmarks you would want to be private?

A few months back I wrote avar.icio.us, which does autocompletion and dynamic suggestion of tags based purely on your own tag coincidence statistics. You can see it in action on Bowen Dwelle's site: try typing "ja" in the tags field - it should autocomplete "javascript" in the textbox and then suggest a couple more tags beneath. (This is all based on Bowen's own tags) Note that autocompletion only works in Mozilloids and IE/Win at the moment.

A popular add-on that makes suggestions from other user's tags is Greg Sadetsky's nutr.icio.us (unfortunately unavailable at the moment). Joshua is building some of those features into del.icio.us core.

<plug>javainetlocator and IP::Country</plug> are also available.

The city data are unreliable. I've posted elsewhere (link1, link2) the reasons why, but will repeat the main points here.

• All IP geolocation techniques assume the user of an IP address lives close to the company which registered the address.
• The above assumption is mostly true if you define 'close' as 'in the same country'.
• In the USA, a lot of people live in (or close to), the same city as the company who registered their IP address. This is because lots of people live in cities and use ISPs which have a presence in that city.
• Most of the world population (and US population) doesn't live in a city with major ISP presence. Their city locations aren't going to be accurate by any IP geolocation technique.
• The commercial IP geolocation vendors (quova, digital envoy) have a business reason for making city geolocation sound accurate. If it wasn't accurate, why would anybody buy their products?
• Conducting a survey that inflates the accuracy of city geolocation is easy - just ensure your survey participants live in a major US cities and you'll achieve high accuracy. One way would be to use server logs from a US financial industry website. Once you have a survey that shows high accuracy, you can sell your product to businesses whose customers don't live in major US cities
• It's extremely difficult to measure accuracy of IP geolocation (even at the country level), so if you make bold claims, no one is going to be in a position to argue.

GeoURL will be down until Friday, 9am EST.

Sorry for the inconvenience.
