Copy MySQL table to big query. If you need to copy all tables, use the loop given at the end. Exit with error code 3 if blob or text columns are found. The csv files are first copied to google cloud before being imported to big query.

Can you help me understand the benefit of require.js?

I'm having trouble understanding the benefit of require.js. Can you help me out? I imagine other developers have a similar interest.

From Require.js - Why AMD:

The AMD format comes from wanting a module format that was better than today's "write a bunch of script tags with implicit dependencies that you have to manually order"

I don't quite understand why this methodology is so bad. The difficult part is that you have to manually order dependencies. But the benefit is that you don't have an additional layer of abstraction.

Convert an interface{} containing a slice of structs to [][]string (used in CSV serialization) [golang reflection example] Runnable example here: http://play.golang.org/p/ZSJRxkpFs9
// Convert an interface{} containing a slice of structs into [][]string.
func recordize(input interface{}) [][]string {
var records [][]string
var header []string // The first record in records will contain the names of the fields
object := reflect.ValueOf(input)
// The first record in the records slice should contain headers / field names
if object.Len() > 0 {
first := object.Index(0)
typ := first.Type()
