摘要： A method and apparatus is provided for determining the most probable cause of a problem observed in a complex multi-host system. The approach relies on a probabilistic model to represent causes and effects in a complex computing system. However, complex systems include a multitude of independently operating components that can cause temporary anomalous states. To reduce the resources required to perform root cause analysis on each transient failure, as well as to raise the confidence in the most probable cause of a failure that is identified by the model, inputs to the probabilistic model are aggregated over a sliding window of values from the recent past.

摘要： A web application receives a user input with a SQL injection attack string that references a function. The application generates a corresponding statement based on the user input string, which the application sends to a database server. Upon receiving the statement, the database server executes the statement that invokes the referenced function. When invoked, the referenced function stores a value. The presence of the stored value indicates that the database server invoked the function. Storing the value indicative of the function invocation identifies a vulnerability of the web application to SQL injection attacks, since the function reference is introduced solely through user input and function invocation is not intended by the application. This provides proof of SQL injection vulnerability of the application.
摘要翻译： Web应用程序使用引用函数的SQL注入攻击字符串接收用户输入。应用程序根据用户输入字符串生成相应的语句，应用程序发送到数据库服务器。数据库服务器收到该语句后，执行调用引用函数的语句。被调用时，引用的函数存储一个值。存储值的存在表示数据库服务器调用了该函数。存储指示功能调用的值标识Web应用程序对SQL注入攻击的漏洞，因为仅通过用户输入引入函数引用，并且应用程序不打算使用函数调用。这提供了应用程序的SQL注入漏洞的证明。

摘要： Techniques are provided for ranking the entities that are identified in a document based on an estimated likelihood that a user will actually make use of the annotations. According to one disclosed approach, usage data that indicates how users interact with annotations contained in documents presented to the users is collected. Based on the usage data, weights are generated for features of a feature vector. The weights are then used to modify feature scores of entities, and the modified feature scores are used to determine how to annotate documents. Specifically, a set of entities are identified within a document. A ranking for the identified entities is determined based, at least in part, on (a) feature vector scores for each of the identified entities, and (b) the weights generated for the features of the feature vector. The document is then annotated based, at least in part, on the ranking.

摘要： Techniques are provided for managing caches in a system with multiple caches that may contain different copies of the same data item. Specifically, techniques are provided for coordinating the write-to-disk operations performed on such data items to ensure that older versions of the data item are not written over newer versions, and to reduce the amount of processing required to recover after a failure. Various approaches are provided in which a master is used to coordinate with the multiple caches to cause a data item to be written to persistent storage. Techniques are also provided for managing checkpoints associated with the caches, where the checkpoints are used to determine the position at which to begin processing recovery logs in the event of a failure.

摘要： Techniques are disclosed herein to automatically learn a template that describes a common structure present in documents in a training set. The structure of the template is compared to the structure of the documents (or at least a part of each document) in the training set, one-by-one, and generalized in response to differences between the template and the document to which the template is currently being compared. If the structure of any particular document is considered too dissimilar from the structure of the template, then the template is not modified. Various generalization operators are added to the template to generalize the template. One such generalization operator is an “OR”, which indicates that only one of “n” sub-trees below the “OR” operator in the template is allowed at the corresponding position in a document.

摘要： Radios synchronize their timing mechanisms using a timing signal that those radios propagate from one radio to another. Radios that are close to each other transmit only during times that none of the other nearby radios is trying to receive. In one scheme, a “master” radio initiates communication while another “slave” radio responds in a pre-determined manner. The master generates and propagates an inverted timing signal to the slave, which propagates approximately the same inverted timing signal to other radios in the slave's cluster. Each radio can be in one of three different modes: “source,” “auto,” and “recipient” modes. A “source” radio generates a timing signal independently. A “recipient” radio uses a received timing signal and forwards it to other radios. An “auto” radio behaves as a “recipient” radio while a timing signal is detectable, but behaves as a “source” radio if the timing signal is lost.

摘要： Techniques for determining scale factor values when encoding audio data are described. According to one technique, a particular scale factor value (SFV) is estimated using an audio quality estimator function that is non-linear. After a certain point, a decrease in noise results in a smaller increase in audio quality. According to another technique, an initial SFV is estimated for each scale factor band (SFB). When estimating the cost of transitioning from one SFB to another, only a proper subset of possible SFVs are considered. The proper subset is based, at least in part, on the initial SFV.

摘要： An automated form filler and script executor is integrated with a web browser engine, which is communicatively coupled to a web crawler, thereby enabling the crawler to identify dynamic web content based on submission of forms completed by the form filler. The crawler is capable of identifying web pages containing forms that require submission, and JavaScript code that requires execution, respectively, for requesting dynamic web content from a server. The form filler systematically completes the form based on various combinations of search parameter values provided by the web page for requesting dynamic content. Duplicate forms are detected, so that the crawler does not unnecessarily re-process forms that are similar to forms that have already been processed. The crawler may also determine which JavaScript links in a page are relevant for execution, so as to avoid unnecessary execution of irrelevant JavaScript links.
