Hi,
I am trying to create a DataTable with a multi row header. I'll exemplify here:
| 2008 | 2009 |
---------------------------------------------------------
| price | qty. | price | qty |
---------------------------------------------------------
| 93993 | 34434 | 34244 | 3434 |
.....
The years headers can be fixed as I don't want to do sorting by that.
Is there a way to do that in Google Visualizations?
I have a two column list consisting of a US zipcode and a count (number of customers in this case). I want to put this data onto a map. Would Google maps API be a good fit for this?
It seems like this would be a common enough type of problem to already have an existing (preferably Java based) solution without having to re-invent the wheel.
Any suggestions?

After test driving Google Chrome for 30 minutes or so, I like it, even if it seems bare-bones at the moment. The obvious way to add a few things I can't live without would be through plugins. Does anyone have any links to resources on how to get started building a plugin/addon for Chrome? Thanks.
I'm trying to make an app that links to Google streetview using latitude/longitude coordinates, and shows a streetview of the nearest road. This is coming from a fairly small and well covered area, so there isn't going to be any coordinates in the middle of the ocean.
Is there a published API showing the get parameters you need to link directly to streetview?
I get an "The remote name could not be resolved: 'mine.com'"
When using this open ID identifier:
https://www.google.com/accounts/o8/site-xrds?hd=mine.com
And it's true, that the mine.com DNS record doesn't exist. But I'm wondering why it goes to look there in the first place. All I want to be doing is to check if the user can login to our hosted domain. Is that really so hard?
What is the easiest and most efficient way to create an auto-increment counter for every data row in google appengine?
basically I want to give every row a unique row_number so that I can overcome the issue of only being able to get the first 1000 results in a select query. I can thus add a counter lies between condition and mine all the entires in the table.

i am using the google maps API (v3). I just realized that a new line showed up at the bottom of my map that says:
Map Data 2010 AND, AfriGIS (Pty) Ltd, Europa Technologies, Inva, Geosysternas SRL, Maplink . . . .
How do i get rid of this?
Its longer than my map so it gets truncated and looks weird, is there any way to fix this (if there is no way to do #1)
hey there,
in my google analytics account there is a page tracked usually opened as a javascript window.open() pop-up (same domain as referring page).
unfortunately, g.a. categorizes the pop-up page as entrance, although it is just a step in the whole navigation flow.
how can i avoid this?
thanks for your help!

To learn from good examples, what are the best open source Google App Engine applications out there?
I don't care if it is Java or Python based.
Please one app per answer. Feel free to add a link to the live app (if there is) and to the project page.
We have #1 and #2 spots we would like to keep, but because of the way things were jumbled we have to migrate to a new domain.
We do not want the new domain to be penalized for duplicate content, we want it to naturally take the spot on Google.

I recently put up a site and I have been doing some SEO.
However I noticed that links from Google search append index.php to my links.
For example a site page which clearly appears as www.example.com/index/why on search together with correct content sample when clicked on ends up in the new browser as www.example.com/index.php/why
Note that on my site all links are redirected to SSL and I use the MVC stucture.
Any directives that am may be missing?
