Ada variables are complex objects. When developing a compiler, you must definitively take that in account. You have several sides to your variables: one you need to be able to handle dynamic variables since the compiler will have to be capable of doing all the operations on all the constant variables just as if you were executing your program and it has to handle all the tests necessary to ensure integrity.

So... we need a library that can handle integers, a library to handle floating points, a library to handle arrays, etc.

Managing your own Drupal Download Site

The other day, I was thinking, it would be nice if I could find the way to manage my own download site so people who use my modules that I do not provide directly on http://drupal.org would still show as expected (i.e. Green in the update window).

I should have thought of it, the deflate module was not installed. That was it, but oh well... 8-)

To tweak your Apache setup, use the following two lines:

Today we again ran in an out of memory error. As we are adding more websites our foot print is growing... Our servers use a VPS that has limited resources and whenever the limit is reached, the system automatically kills processes. How the VPS selects the process to kill isn't clear to me, but twice it has been our database manager meaning that all of a sudden all the websites stop working.

So... We got an extra bit of RAM because our package allowed it, but that's still small.
