This is a very useful map application. users can browse local data from the Census Bureau's American Community Survey, based on samples from 2005 to 2009. User can choose from population, income, family and education category to visually check the spatial pattern of each variable and may help them better understand the demographic distribution in the area they are interested.

SQL - Insert Multiple Records into one tables at one time

How are you going to insert multiple records into a table at one time?

Here is the code you can do that:

Insert into Table
(Column1, Column2, Column3)

select Value01, Value02, Value03
Union ALL

select Value11, Value12, Value13
Union ALL

select Value21, Value22, Value23

It works and save time by avoiding multiple insert scripts.

Coordinate coversion

If you have some knowledge about geography, you my be familiar with different projection system. The projection system will display earth surface on the flat paper. Sometimes you may need to convert coordinates into different projection system. You can do this with GIS software. But you want to do it online, there is website for this task.

It is:

Envelope-free to deposit checks in ATM

Wachovia Bank now can deposit your check without envelopes. You do not have to even put the amount y0u are going to deposit. The ATM machine can read and scan checks and automatically know how much money that will be. You can deposit multiple checks at one time. It is very convenient. Then if you want a receipt, you did have a choice to get a receipt with scanned check images.

Not sure if the ATM machines in other banks have the same kind of features, I do find this new feature is very useful to customers.
