Abstract: Exposing a leap second to a plurality of applications includes identifying that a positive leap second should be added to the end of a chosen date. Based on the occurrence of the positive leap second, a first conversion component is exposed to a first application. The first conversion component presents, over a period of two seconds of actual time, a last second of the chosen date as if it is one second of system time. Based on the occurrence of the positive leap second, and based on a second application opting in to leap seconds, a second conversion component is exposed to the second application. The second conversion component presents an extra 61st second of system time at the end of a last minute of the chosen date.

Abstract: Content management in a collaboration system. Ease-of-use of shared content is facilitated. A URL is presented in a user interface. The system determines (e.g., based on user preferences) whether to display the content corresponding to the URL in a browser at the user device, or whether to display the content corresponding to the URL using a non-browser application. If the user device is configured to display the content corresponding to the URL using a non-browser application, then when the user clicks or touches or hovers, or otherwise indicates a selection of a URL, the system displays the content using the non-browser application. In this situation, the system retrieves the content from the collaboration system, stores a local instance of the content in local storage of the user device, and opens the local instance using the non-browser application. Local instance edits are synchronized with the collaboration system using a synchronization protocol.

Abstract: Described herein is a system and method for latency-aware thread scheduled. For each processor core, an estimated cost to schedule a particular thread on the processor core is calculated. The estimated cost to schedule can be a period of time between the scheduling decision and the point in time where the scheduled thread begins to run. For each processor core, an estimated cost to execute the particular thread on the processor core is calculated. The estimated cost to execute can be a period of time spent actually running the particular thread on a particular processor core. A determination as to which processor core to utilize for execution of the particular thread based, at least in part, upon the calculated estimated costs to schedule the particular thread and/or the calculated estimated costs to execute the particular thread. The particular thread can be scheduled to execute on the determined processor core.

Abstract: Communicating a low-latency event across a virtual machine boundary. Based on an event signaling request by a first process running at a first virtual machine, the first virtual machine updates a shared register that is accessible by a second virtual machine. Updating the shared register includes updating a signal stored in the shared register. The first virtual machine sends an event signal message, which includes a register identifier, through a virtualization fabric to the second virtual machine. The second virtual machine receives the event signaling message and identifies the register identifier from the message. Based on the register identifier, the second virtual machine reads the shared register, identifying a value of the signal stored in the shared register. Based at least on the value of the signal comprising a first value, the second virtual machine signals a second process running at the second virtual machine.

Abstract: A verified stack trace can be generated by utilizing information contained in a shadow stack, such as a hardware protected duplicate stack implemented for malware prevention and computer security. The shadow stack contains return addresses which are obtainable without requiring an unwinding of the traditional call stack. As such, triaging based on return address information can be performed more quickly and more efficiently, and with a reduced utilization of processing resources. Additionally, the generation of a verified stack trace can be performed, with such a verified stack trace containing return addresses that are known to be correct and not corrupted. The return addresses can either be read from the traditional call stack, or derived therefrom, and then verified by comparison to corresponding return addresses from the shadow stack, or they can be read directly from the shadow stack.

Abstract: A program is executed using a call stack and shadow stack. The call stack includes frames having respective return addresses. The frames may also store variables and/or parameters. The shadow stack stores duplicates of the return addresses in the call stack. The call stack and the shadow stack are maintained by, (i) each time a function is called, adding a corresponding stack frame to the call stack and adding a corresponding return address to the shadow stack, and (ii) each time a function is exited, removing a corresponding frame from the call stack and removing a corresponding return address from the shadow stack. A backtrace of the program's current call chain is generated by accessing the return addresses in the shadow stack. The outputted backtrace includes the return addresses from the shadow stack and/or information about the traced functions that is derived from the shadow stack's return addresses.

Abstract: Exposing a leap second to a plurality of applications includes identifying a system setting enabling leap second support and that a positive leap second should be added to the end of a chosen date. Based on the system setting enabling leap second support and based on the occurrence of the positive leap second, a first conversion component is exposed to a first application. The first conversion component presents, over a period of two seconds of actual time, a last second of the chosen date as if it is one second of system time. Based on the system setting enabling leap second support, based on the occurrence of the positive leap second, and based on a second application opting in to leap seconds, a second conversion component is exposed to the second application. The second conversion component presents an extra 61st second of system time at the end of a last minute of the chosen date.

Abstract: A variety of methods for driving electro-optic displays so as to reduce visible artifacts are described. Such methods include (a) applying a first drive scheme to a non-zero minor proportion of the pixels of the display and a second drive scheme to the remaining pixels, the pixels using the first drive scheme being changed at each transition; (b) using two different drive schemes on different groups of pixels so that pixels in differing groups undergoing the same transition will not experience the same waveform; (c) applying either a balanced pulse pair or a top-off pulse to a pixel undergoing a white-to-white transition and lying adjacent a pixel undergoing a visible transition; (d) driving extra pixels where the boundary between a driven and undriven area would otherwise fall along a straight line; and (e) driving a display with both DC balanced and DC imbalanced drive schemes, maintaining an impulse bank value for the DC imbalance and modifying transitions to reduce the impulse bank value.

Abstract: Systems and methods enable most valuable players (MVPs) of a gameplay session to play a bonus gameplay session where other players (non-MVP players) participate as player-spectators in online video games and, through a collective voting mechanism or through active interaction, determine the occurrence of certain events or contents of the bonus gameplay in real time. In this manner, non-MVP players are able to directly affect the course of the bonus gameplay.

Abstract: Generic adjustable in-ear monitors (IEMs) may suffer from a limited range of resilient ear plugs that may not adequately fit each user, and the user may prefer different ear plugs for different purposes (e.g., the user's interest in secure fitment may be higher when exercising, while the user's interest in comfort may be higher when the user is relaxing). The presently disclosed technology is directed to IEMs that permit a user to adjust without removing and replacing an associated ear plug. Instead, the ear plug is adjustable by the user to achieve a desired fit and may be adjusted repeatedly for different desired fits and/or different users.
