Abstract: An air channeling sub-system may include a mechanical cooling section and a direct evaporative cooling section. The direct evaporative cooling section may be downstream from the mechanical cooling section. Cooling air is channeled through the air channeling sub-system and into the room. If a first set of control conditions is met, the air channeling sub-systems is operated in an adiabatic mode. The adiabatic mode includes channeling cooling air through the direct evaporative cooling section to evaporate water into the cooling air. If a second set of control conditions is met, the air channeling sub-system is operated in a hybrid mode. The hybrid mode includes channeling cooling air through the mechanical cooling section to remove heat from the cooling air and channeling the cooling air through the direct evaporative cooling section to evaporate water into the cooling air.

Abstract: Described are techniques for prioritizing devices to receive updates to an application executing on a device. Event data indicative of use of the application, the device, and other information associated with a user is obtained. For example, event data for a user account across many different devices may be obtained. Deployment parameters may specify how an update is to be distributed, such as maximum number of devices to deploy to, timing of deployment, and so forth. Based on the event data and the deployment parameters, a subset of the devices executing the application are selected. The update may then be distributed to the subset.

The circuit board further includes a signal pin having a first end, a second end, and an intermediate portion between the first end and the second end. The first end of the signal pin is in contact with the contact pad, where the signal pin has a resonant frequency outside a predetermined frequency range.

Abstract: A data center row infrastructure module enables rapid deployment of a computing room enclosure for computer systems that provides intake air circulation to, and exhaust air removal from, the computer systems in the enclosure. The data center row infrastructure module includes free-standing exhaust plenum structures encompassing opposite sides of the enclosure and a plenum module spanning a top end of the enclosure between the free-standing exhaust plenum structures. Each free-standing exhaust plenum structure includes an internal exhaust air plenum that directs exhaust air received from the enclosure through an exhaust air outlet on a top end of the free-standing exhaust plenum structure. The plenum module establishes a bottom end of a cooling air plenum above and separate from the enclosure and between the free-standing exhaust plenum structures. Some plenum modules can direct cooling air directly to the enclosure as intake air.

Abstract: A first representation of a feature processing recipe is received at a machine learning service. The recipe includes a section in which groups of variables on which common transformations are to be applied are defined, and a section in which a set of transformation operations are specified. The first representation of the recipe is validated based at least in part on a library of function definitions supported by the service, and an executable version of the recipe is generated. In response to a determination that the recipe is to be executed on a particular data set, a set of provider network resources is used to implement a transformation operation indicated in the recipe.

Abstract: Methods, apparatus, and computer-accessible storage media for remotely updating an executing process that receives I/O requests on I/O port(s), stores write data to a write log on local storage, and uploads data from the write log to remote storage. An update for the process is detected and downloaded, and an updated process is instantiated from the update. The current process is directed to perform a shutdown for update during an update window. In response, the current process saves its current configuration, flushes an in-memory portion of the write log to local storage, and releases its I/O port(s). The updated process loads the saved configuration, detects that the port(s) have been released, and starts accepting I/O requests on the ports. During flushing, the current process flushes current data in memory while continuing to append new write data, stops accepting new write requests, and then flushes the new write data.

Abstract: A system and method for management and processing of resource requests is provided. A content delivery network service provider receives a DNS query from a client computing device. The DNS query corresponds to a requested resource from the client computing device. The content delivery network service provider associates the client computing device with a cluster of other client computing devices. Based on routing information for the cluster, the content delivery network service provider routes the DNS query. The process can further include monitoring performance data associated with the delivery of the requested resource and updating the routing information for the cluster based on the performance data for use in processing subsequent requests from client computing devices in the cluster.

Abstract: A client and a server negotiate a cipher suite as part of establishing a TLS connection. Cipher suites are rated with an associated level of security. In one example, the client and the server maintain a historical record that identifies the cipher suites used in previous TLS connections between the client and the server. The client and the server determine a minimally acceptable cipher suite rating based at least in part on the historical record of previously used cipher suites. If the negotiated cipher suite has a rating less than the determined minimally acceptable cipher suite rating, the TLS connection may be terminated, the cipher suite may be renegotiated, or other corrective action may be taken. In another example, the client and the server exchange digital certificates, and the digital certificates identify cipher suites for use with a TLS connection that are acceptable to the certificate owner.

Abstract: An electronics adapter and method are disclosed herein. The electronics adapter can include a plurality of interface ports, with each interface port from the device coupled to a processor from a plurality of processors, and a controller communicatively coupled to the interface ports. The controller may be configured to determine a function or transaction attributes, which are serviced by instructions executed by one of the processors. The controller may be further configured to determine at least one interface port on the adapter to transmit the transaction based on the function or the attributes using an updatable mapping between the function or the attributes and the interface port, and transmit a request for the transaction using the interface port for processing of the transaction by the processor coupled to the interface port.

Abstract: Data may be securely stored onto a shippable data storage device in order for the client data to be protected during shipment to the remote storage service provider. The service provider prepares a shippable storage device and ships it to the client. The service provider also sends client-keys and security information to the client, separate from the shippable storage device. A client-side data transfer tool authenticates the shippable storage device using the security information. The data transfer tool generates keys to encrypt the customer data. The data transfer tool then uses the client-keys received from the service provider to encrypt the tool-generated keys. The encrypted data and the encrypted tool-generated keys are transferred onto the shippable storage device. The shippable storage device is then shipped back to the service provider, which decrypts the tool-generated keys and the encrypted data before importing the data.

Abstract: Features are disclosed for improving the robustness of a neural network by using multiple (e.g., two or more) feature streams, combing data from the feature streams, and comparing the combined data to data from a subset of the feature streams (e.g., comparing values from the combined feature stream to values from one of the component feature streams of the combined feature stream). The neural network can include a component or layer that selects the data with the highest value, which can suppress or exclude some or all corrupted data from the combined feature stream. Subsequent layers of the neural network can restrict connections from the combined feature stream to a component feature stream to reduce the possibility that a corrupted combined feature stream will corrupt the component feature stream.
