Flickr – the best photo sharing site is now ready to talk in terms of latitudes and longitudes says the flickr blog! Thats right flickr now supports geo-tagging! That is absolutely awesome! What is geotagging? Wikipedia has a detailed answer. The interface is pretty sweet (all ajax enabled) and you can drag multiple photos onto a location on a map and it will automatically geo tag it for you. The map is Yahoo Maps based and the searching could use some help. But overall its a step in the right direction and I give it a big thumbs up.

Here’s a screenshot – GeoTagging in action:

I encountered a few issues when starting to develop on Windows Vista. I had my whole enviornment setup and I decided to write a quick little asp.net app and test it out….Once I hit F5 in studio – I got a msgbox:

Unable to cast object of type ‘System.Web.HttpDebugHandler’ to type ‘System.Web.HttpApplication’.

————————————————

 

Unable to start debugging on the web server.  

[InvalidCastException]: Unable to cast object of type ‘System.Web.HttpDebugHandler’ to type ‘System.Web.HttpApplication’.   at System.Web.Hosting.PipelineRuntime.ExecuteStateHandler(IntPtr& managedRequestContext, IntPtr nativeRequestContext, IntPtr moduleData, Int32 flags)

So I figured it was probably something to do with the new Integrated mode in IIS and VS2005 has no clue about it. So I moved the app to a new Application Pool in IIS7 that runs in ISAPI mode and now everything works!

I have recently installed Windows Vista Beta 2 and started playing around with it. First impressions are good….although as a developer the security features like UAC are pretty in your face (probably good for end users). I immediately disabled that by editing the local system policy by running:

 secpol.msc ->  Local Policies -> Security Options -> Disable the policy “User Account Control: Run all administrators in Admin Approval Mode”

That definitely made those annoying messages go away! I had to install Visual Studio 2005 and I was thinking of playing with Atlas. Once I got that installed and tried to create a sample website Visual Studio was barking back at me saying: 

Error HRESULT E_FAIL has been returned from a call to a COM component

Now what? Well supposedly vista will not start application in admin mode even if you are logged in as an administrator.  The fix: Right click on the shortcut to studio and click Run as Administrator and it works like a charm.

Here is a link to Microsoft KB which shows how to configure specific applications to always run as admin.
