Abstract: At an action implementation layer of a virtual traffic hub, a packet is obtained from a first isolated network. A first action, generated at a decision making layer of the hub based on a first route table of the hub, is performed, resulting in transmission of at least one network packet to a first destination. In response to a second packet, obtained at the action implementation layer from a source outside the first isolated network, a second action is performed, resulting in transmission of at least one packet to a second destination. The second action is generated based on a second route table of the hub.

Abstract: Moments of inertia for an object, such as an aerial vehicle, may be determined by suspending the object from at least two filars, or cables, that are aligned in parallel and of equal length. After imparting a rotation upon the object about a vertical axis, data regarding oscillations of the object may be captured using an inertial measurement unit associated with the object. The captured data may be used to calculate a moment of inertia about the vertical axis, and to determine a vector corresponding to the vertical axis. After suspending the object, imparting rotations to the object and capturing data with the object in a number of orientations, a moment of inertia tensor may be calculated about the object's principal axes based on the moments of inertia about vertical axes in such orientations and the vectors.

Abstract: Techniques for distributed computing system node management are described herein. In some cases, internal compute nodes (i.e., compute nodes that are allocated to the distributed system) may be mutually trusted such that they may freely establish communications with one another. By contrast, external compute nodes (i.e., compute nodes that aren't allocated to the distributed computing system) may be untrusted such that their access to the distributed system may be regulated. In some cases, one or more of the compute nodes within the distributed computing system may maintain respective collections of system view information. Each respective collection of system view information may include, for example, information associated with the corresponding compute node's view of the distributed computing system based on information that is available to the corresponding compute node.

Abstract: This disclosure describes techniques implemented partly by a cloud-based service provider for providing a sentiment-analysis service to determine whether sentiments, or attitudes, of users have significantly decreased. The sentiment-analysis service is composed of various services provided by the cloud-based service in order to determine significant negative deviations in sentiment of users towards an entity. Further, the sentiment-analysis service utilizes various techniques, such as encryption, to privatize the process such that private user information is protected. In some examples, an entity may not know the content of communications or the reasons the user's sentiment has dropped, but may be alerted of a general negative change in sentiment towards the entity by the user.

Abstract: A machine learning engine can be used to identify inconsistencies and errors in a plurality of bug reports and to glean new information from the bug reports. Bug data associated with a large number of bug reports from different bug categories may be processed and used by a machine learning model of the machine learning engine. The machine learning engine can extract bug attributes from the bug data of a first bug. The machine learning engine can then compare the attributes of the first bug to a machine learning model created using a plurality of second bug reports. Based on then similarity between the first bug report and the second bug reports, the machine learning engine can apply, or correct, various attributes of the first bug report. The machine learning model may be updated over time by the machine learning engine as data correlations evolve.

Abstract: A remote-controlled data center floor tile of a raised floor plenum is adjustable by a remote control system to selectively direct air supplied from the raised floor plenum to cool particular rack computing systems in a data center. Floor tiles can include one or more remote-controlled flow control elements that can be independently adjusted to different particular configurations to direct air to one or more specific targets. A remote control system can independently adjust various flow control elements configurations in a network of various floor tiles to manage environmental conditions in a data center, including mitigating localized temperature hotspots at particular portions of a rack computing system. Hotspot mitigation can involve responding to detection of a hotspot at a target location by configuring one or more flow control elements to direct air supplied from the raised floor plenum to supply additional air to cool the target location.
