I was bored today so I created a very simple and fast php script to plot the location for a given IP and display other IP information (such as lattitude, longitude, Country, State, Area code, ISP, etc.) on a Google Map using the Maxmind web service and the Google Maps API.

The link in the balloon points domaintools.com and does a whois lookup on the IP for detailed information on the ISP (internet service provider).

Here is a working demo (hard coded IP).

In order for this script to work on your site, you will need a MaxMind GeoIP City/ISP/Organization Web Service Key (50,000 lookups for $20.00) and a Google Maps Key (free). There are other IP to Lat/Long Web services out there but Maxmind is by far the most accurate (none are 100% accurate).

To render the location of an IP on the map, send the IP via the query string such as…

http://www.yourDomain.com/MaxmindGoogleMap/index.php?ip=98.195.83.50

Here is the script. Copy the contents to a .php file and edit the 2 keys. That’s it!

.net versions rant

November 21st, 2007

I am fairly certain the .NET versioning (numbering release) scheme is the dumbest ever created. Seriously who in their right mind does a point release that is a extension of the previous point but not the one before that (2.0 -> 3.0)? Then 3.0 -> to 3.5? wtf? Remember 1.0 and 1.1? Hmmm. How does that fit in? Oh yea, it doesn’t.

It went like this…

1.0 to 1.1. Perfect. Basically the 1.0 framework fixed with a couple new things. That’s actually how it took place.

Then 2.0. A whole new framework. Yay! We are good at this point.

Then 3.0. Huh? Another new framework? Yay!? Wait, no, huh? It’s not a framework? It’s a extension but only for 2.0 and not related at all to 1.0 or 1.1? Oh good heavens MS.

Then 3.5 Another extension to 2.0 or actually 3.0? Ok, now I’m getting mad. What happened to 3.1, 3.2, etc.?

What’s next? 8.0 with 10.0 extentions?

Might as well number it 38.5. What’s the difference at this point? There is NO consistency anyway and the higher the number the better right?

Anyway here is the 2.0 -> 3.5 relationships…

Seriously, if you know what the hell MS was thinking, post a comment.
