A method for constructing a customized web analytics application comprises providing a base analytics code, including a base data mining code and a plurality of tokens corresponding to unincorporated code snippets, and incorporating code snippets as selected to create the application where each code snippet is configured to track a different custom web analytic. The system displays a selection of at least one web analytic to track and receives user selection of at least one displayed web analytic to track over a wide area network. Once selected, an unincorporated code snippet corresponding to each selected displayed web analytic is retrieved from a library of such code snippets. The code snippet is then substituted in place of its corresponding token within the base analytics code to create a customized analytics code. The customized code is finalized by removing the remaining tokens and the finalized code transmitted to the user for incorporation into their web pages.

Methods, devices, and systems for detecting return-oriented programming (ROP) exploits are disclosed. A system includes a processor, a main memory, and a cache memory. A cache monitor develops an instruction loading profile by monitoring accesses to cached instructions found in the cache memory and misses to instructions not currently in the cache memory. A remedial action unit terminates execution of one or more of the valid code sequences if the instruction loading profile is indicative of execution of an ROP exploit involving one or more valid code sequences. The instruction loading profile may be a hit / miss ratio derived from monitoring cache hits relative to cache misses. The ROP exploits may include code snippets that each include an executable instruction and a return instruction from valid code sequences.

A method for determining if a web browser is being operated by a human or a non-human agent, based on analysis of certain aspects of how a user interacts with a webpage. By placing a code snippet into the code of a webpage prior to a given user accessing that webpage, one is able to evaluate the user's actions in order to predict the type of user. The predictions are made by acquiring information on how the user loads, navigates, and interacts with the webpage and comparing that information with statistics taken from a control group. Performance metrics from all webpages containing similar code elements are compiled by analysis servers and made available to the operator of a webpage through a variety of reporting mediums. By compiling such performance metrics, the method helps combat and prevent malicious automated traffic directed at advertisements and other aspects of a given webpage.

Provided is a method and a web-site integration system to integrate payment mechanisms into a commercial website that offers online merchants a flexible, user-friendly and customizable wizard to integrate payment mechanisms into their online commercial websites without having to understand the detailed intricacies of an API or other computer code. The wizard steps the merchant through creating an account to obtain credentials and educates the merchant on the page flows of the payment mechanism that the merchant wishes to integrate. Then, the wizard generates code snippets and files to be downloaded by the merchant and to be easily inserted into key pages of the merchant's online commercial website. The merchant can then test the completely integrated code in a developer's sandbox or go live with the completely integrated code.

Optimizations are programmatically applied by a compiler (preferably, a just-in-time or “JIT” compiler), and enable achieving improved performance while a variable acts as a global constant, yet also allow code to execute correctly if the global constant's run-time value changes from the value on which the optimization was originally based. Code snippets that dynamically patch executable code are described, where these code snippets take corrective actions to enable correct program execution following a run-time change to the value of a glacial constant. A backup recovery path may also be maintained, where this path provides code that is executed in the event of a change to a glacial constant and that treats the glacial constant as a variable. Recompilation may also be used after a change to a glacial constant, where the originally-compiled code has made an assumption about the glacial constant's value that is no longer accurate. Combinations of these approaches may be used.

The invention provides a method used for realizing MVC by taking JavaScript as a controller. Models and view-interaction with a user are realized by HTML under JavaScript MVC. Models-realization of service logic in a system and generation of HTML code snippets are realized by JSP. The models mainly provide part of code snippets for the view but do not take charge of the arrangement of entire page display and the control of page switching. The controller, which is realized through JavaScript, is a bridge between the models and the view and determines which models are shown on the page. Through JavaScript MVC, the method ensures convenient operation of developers and increases the development efficiency to develop program quickly. Moreover, because JavaScript MVC is based on Ajax, local page refreshing is realized and friendlier interfaces can be provided for users to ensure excellent user experience.

For each method usage, a representative code snippet may be selected and stored in the knowledge base (210) in association with metadata (230 1, 230 2, ...230 n). The programming context may be obtained and used to query the knowledge base (210) to retrieve one or more code snippets for recommendation. The recommended code snippets may be ranked to improve the utility and user friendliness, and the metadata (230 1, 230 2,...230 n) may be used to provide variation points and possibly other auxiliary information to improve the operation efficiency and user experience.

Techniques enabling an end-user to specify complex concepts consisting of code abstractions, design abstractions and architectural abstractions in rule form are disclosed. In one embodiment, a graphical user interface is provided to guide a user through the process of entering concept specification information in order to define concepts, including the provision of one or more code snippets that are subsequently analyzed to assist the user in specifying the concept.

A routine for tagging and tracking source code may be implemented in a software development environment. The routine begins upon the identification of a defect in a software product or system. Once the defect has been identified and rectified, a search of other source code (typically located in a source code management system that supports version control) is specified. Using the search specification, the system automatically identifies the code snippet to be searched and begins searching the identified codebase for duplicates. A ticket or service record is then created for every duplicate / similar code snippet found during the search. The ticket / record enables software defect tracking to be carried out on the newly-located instances of the code. The system also automatically manages the code snippets identified by the duplicate detection.

Reusable JSP code snippets are defined and instrumented for Website testing and production. A user may define tile definitions in a markup language file for a number of JSP code snippets to be included in a store page. Upon receiving store inputs comprising tile definitions and jar files for the features, tables may be generated that map features to stores and features dependencies to features. Based on the tables, the store inputs may be validated. If no error occurs, run time files may be generated and JSP code snippets may be instrumented to the appropriate location for Website testing and production.
