Abstract: A mechanism for referencing a portion of a document. A method includes identifying, by a processing device of a user device, a portion of a document, the portion selected by a user of the user device. The method also includes displaying, by the processing device, the selected portion of the document as a graphical representation of an icon on the user device. The method also includes detecting, by the processing device, a reference to the icon displaying the selected portion of the document, the reference performed by the user. The method further includes providing, by the processing device, the referenced selected portion of the document associated with the icon to the user.

Abstract: Certain aspects and features provide generation or simulation of sensory data that would otherwise come from Internet-of-things (IoT) sensors in reproducible and controllable way. Thus, the response of a system to very large numbers of sensors can be tested without acquiring and deploying a very large number of sensors for test and development purposes. In some examples, a processing device coupled to a network interface identifies a stored function of time describing a locally sensed property for a simulated sensor. The locally sensed property corresponds to at least one event taking place in a virtual environment. The processing device can determine values of an input variable produced by the stored function of time. The values can be wrapped in a communication protocol to produce messages that are transmitted over the network interface.

Abstract: This application relates to receiving, by a processing device executing a virtual machine, bytecode including an object to be loaded into a memory space, the object being tagged with a garbage collection descriptor. The garbage collection descriptor is generated according to an annotation to the object in a source code. The application further provides for determining, in view of the garbage collection descriptor, a region of the memory space to store the object, in which the memory space includes a first region to store a first set of objects that have survived less than a determined number of rounds of garbage collection and a second region to store a second set of objects that have survived at least the determined number of rounds of garbage collection in the first region. The application further provides for storing the object in the region of the memory space and adding the object to one of the first objects or the second set of objects in view of the region.

Abstract: Systems and methods for controlling access to a private partition on a storage device are disclosed for. An example system includes a token reader that detects a hardware token storing a private key and obtains the private key stored on the hardware token. The system also includes a partition controller that determines whether the private key unlocks a private partition on a storage device. In response to determining that the private key unlocks the private partition, the partition controller unlocks the private partition on the storage device. The private partition is invisible to an operating system executing in the computer system when the private partition is locked.

Abstract: Mechanisms for transferring data from a source computing device to a target computing device are provided. A filename identifier (ID) that identifies a file stored on the source computing device is presented on a display device. A selection of the filename ID is received. A unique identifier is generated, and association data that associates the unique identifier with the file is generated. The unique identifier is encoded into a coded image. The coded image is presented on the display device. A first file transfer request is received via a communications interface from a target computing device to transfer the file via the communications interface to the target computing device. The first file transfer request includes an identifier. Responsive to receiving the first file transfer request, the file is sent to the target computing device.
