Abstract: A computer system identifies malicious Uniform Resource Locator (URL) data items from a plurality of unscreened data items that have not been previously identified as associated with malicious URLs. The system can execute a number of pre-filters to identify a subset of URLs in the plurality of data items that are likely to be malicious. A scoring processor can score the subset of URLs based on a plurality of input vectors using a suitable machine learning model. Optionally, the system can execute one or more post-filters on the score data to identify data items of interest. Such data items can be fed back into the system to improve machine learning or can be used to provide a notification that a particular resource within a local network is infected with malicious software.

Abstract: Unpredictable action of a physical device provides a truly random number from a “smart top,” including a spinner, preferably self-centering, such as a segment of a sphere. A housing containing a CPU and memory device is made to rotate in a plane parallel to a supporting surface, that plane containing the maximum moment of inertia of the apparatus. A central axis, located or self-locating, near a center of mass of the apparatus provides a contact “point” (pointed or not), shaped to reduce a moment arm of friction acting on the device when spinning on a rigid surface. Executables (programs) track rotation about the central axis, outputting a corresponding random number to other executables using it to control a meaningful outcome. One embodiment may be implemented in a smart phone equipped with a self-centering spinner.

Abstract: A gas-lift system includes a first valve configured to provide selective communication of a wellbore fluid between an interior of a production tubing an annulus defined exterior to the production tubing, a second valve configured to provide selective communication of the wellbore fluid between the interior of the production tubing and the annulus, and one or more control lines coupled to the first valve and the second valve. The one or more control lines apply a pressure differential to the first and second valves. The first valve is configured to actuate from an open position to a closed position in response to the pressure differential reaching a first pressure differential, and wherein the second valve is configured to actuate from an open position to a closed position in response to the pressure differential reaching a second pressure differential that is different from the first pressure differential.

Abstract: The present disclosure provides a system and method for creating websites that is accessible to people without significant web development or programming experience. The disclosed method combines a graphical approach with a logic-based approach by providing a user interface in which site creators may place variant content elements, or “variants.” Placing variants allows the website to dynamically change its appearance based on context. Variants are presented in response to fulfilments of one or more rules, which are created using conditional statements made up of vernacular strings and symbols. Thus, creating rules in order to trigger displays of particular elements is easy for a lay person, and allows for enhanced flexibility in creating websites.
