That s useful for testing, but imagine what would happen if you forgot that the script was there and the script made it onto your production site! Anyone who found the URL to your script (http://example.com/testing.php) could delete your users with a single request. That s why it s important, even in quick one-off scripts, to include a security check, as follows: < php /** * This script generates users for testing purposes. */ // These lines are all that is needed to have full // access to Drupal's functionality. include_once 'includes/bootstrap.inc'; drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL); // security check; only the site administrator may execute global $user; if ($user->uid != 1) { print t('Not authorized.'); exit(); } db_delete('users') ->condition('uid', '1', '>') ->execute(); for ($i = $name = $pass = $mail = $status 2; $i <= 10; $i++) { $i; md5(user_password()); $name .'@localhost'; = 1;

Note It is also possible to perform a pre-JIT of an assembly when installing your application using the

ngen.exe command-line tool that ships with the .NET 4.0 Framework SDK. Doing so may improve startup time for graphically intensive applications.

db_insert('users') ->fields(array('name' => $name, 'pass' => $pass, 'mail' => $mail, 'status' => $status, 'created' => time(), 'access' => time())), ->execute(); } print t('Users have been created.'); Here are two take-home lessons: Write security checking even into quickly written scripts, preferably working from a template that includes the necessary code. Remember that an important part of deployment is to remove or disable testing code.

In addition to CIL instructions, a .NET assembly contains full, complete, and accurate metadata, which describes each and every type (e.g., class, structure, enumeration) defined in the binary, as well as the members of each type (e.g., properties, methods, events). Thankfully, it is always the job of the compiler (not the programmer) to emit the latest and greatest type metadata. Because .NET metadata is so wickedly meticulous, assemblies are completely self-describing entities. To illustrate the format of .NET type metadata, let s take a look at the metadata that has been generated for the Add() method of the C# Calc class you examined previously (the metadata generated for the Visual Basic version of the Add() method is similar).

TypeDef #2 (02000003) ------------------------------------------------------TypDefName: CalculatorExample.Calc (02000003) Flags : [NotPublic] [AutoLayout] [Class] [AnsiClass] [BeforeFieldInit] (00100001) Extends : 01000001 [TypeRef] System.Object Method #1 (06000003) ------------------------------------------------------MethodName: Add (06000003) Flags : [Public] [HideBySig] [ReuseSlot] (00000086) RVA : 0x00002090 ImplFlags : [IL] [Managed] (00000000) CallCnvntn: [DEFAULT] hasThis ReturnType: I4 2 Arguments Argument #1: I4 Argument #2: I4 2 Parameters (1) ParamToken : (08000001) Name : x flags: [none] (00000000) (2) ParamToken : (08000002) Name : y flags: [none] (00000000) Metadata is used by numerous aspects of the .NET runtime environment, as well as by various development tools. For example, the IntelliSense feature provided by tools such as Visual Studio 2010 is made possible by reading an assembly s metadata at design time. Metadata is also used by various object-browsing utilities, debugging tools, and the C# compiler itself. To be sure, metadata is the backbone of numerous .NET technologies including Windows Communication Foundation (WCF), reflection, late binding, and object serialization. 15 will formalize the role of .NET metadata.

The main thing to remember about security in connection with AJAX capabilities such as jQuery is that although you usually develop the server side of the AJAX under the assumption that it will be called from JavaScript, there s nothing to prevent a malicious user from making AJAX calls directly (e.g., from command-line tools like curl or wget, or even just by typing the URL into a web browser). Be sure to test your code from both positions.
