CORS Cross Origin Resource Sharing Javascript

For many years we were stuck with JSONP if we needed to make a cross domain query.
JSONP was OK except for one major point: The amount of data to send where limited by max URL length and then again it had to be URI encoded.
Now we have a solution supported by all browsers except IE7 & Opera (for some reason).

Google Translate using JSONP

We have a web page.
In this page there is a set of Fields (input-text/ textarea) with Greek (or whatever google supports) text content.
There are some corresponding Fields where we like to have the english translation.
First get a key from Google API console
You have to remember that max URL length is 2038 characters for IE, that gives less than 1K for the string to translate. You can get more (a lot) from chrome, firefox, opera (>64K).
Google says that you can to it with POST instead of GET, but that is another post.

Protect post from copy paste

Friends keep asking me how to protect their blog posts from being copied.
As you can see I have no protection for my blogs because I think that the effort is futile. I'v seen posts of mine plainly copied in other blogs. In some cases they give a reference to my blog, and for those I am really happy.
In other cases they have no reference even though they just copied and pasted without any work of their own.
Still, my friends want to restrict copy-paste, so I prepared a list of the available solutions:

Database Version Control

There are two types of projects I am involved in these days.

1. Custom enterprise applications where we design the database and manage it.
2. Web applications, that we host, where each customer has his own copy of the database.

In both cases there are many copies of the database installed.

• Developer databases
• Test database (both internal and customer)
• Production database

It is obvious that these databases should be under some Version Control so that can be easily synchronized.
Usually when a database is upgraded, a new version of the application is issued. If only one application is using the database then application-database sync is easy.
When multiple applications are using the same database then this problem is quite difficult to solve.
This is my solution to database versioning problem:
