Abstract: Determining a recommendation to convert a block of code into a serverless function based on analysis of code in execution in a cloud computing environment is disclosed. The block of code can be correlated to high levels of computing resource utilization that can inflate a cost of deploying a corresponding application in the cloud computing environment by prophylactically increasing an amount of provisioned computing resources to accommodate the high-utilization of the block of code. Converting the block of code into a serverless function can reduce the cost via offloading the functionality from the code into a function call supported by the cloud computing environment in an as-needed capacity, thereby reducing the amount of prophylactically provisioned computing resources. The recommendation can occur continuously in a production environment and cot-to-utilization information can render to facilitate identification of code block conversion targets.

Abstract: A method for detecting threat pathways using sequence graphs includes constructing a sequence graph from a set of data containing information about activities in a telecommunications service provider network, where the sequence graph represents a subset of the activities that occurs as a sequence, providing an embedding of the sequence graph as input to a machine learning model, wherein the machine learning model has been trained to detect when an input embedding of a sequence graph is likely to indicate a threat activity, determining, based on an output of the machine learning model, whether the subset of the activities is indicative of the threat activity, and initiating a remedial action to mitigate the threat activity.

Abstract: A method and system for an enhanced weighted fair queuing technique for a resource are provided. A plurality of request streams is received at a requestor, each request stream including request messages from a process executing on the requestor. The request messages of each request stream are apportioned to an input queue associated with the request stream; each input queue has a weight. A virtual finish time is determined for each request message based, at least in part, on the weights of the input queues. A sequence of request messages is determined based, at least in part, on the virtual finish times of the request messages. The sequence of request messages is enqueued into an output queue. The sequence of request messages is sent to a resource, over a connection, which provides a service for each process.

Abstract: A subsea control bundle umbilical comprises: a carrier pipe; a bundle of elongate functional elements being tubes and/or cables that extend longitudinally within the carrier pipe; and spacers spaced apart longitudinally along the bundle. The spacers support the functional elements of the bundle and are movable longitudinally relative to the carrier pipe upon insertion during assembly, and also during installation of the umbilical and in use. As the umbilical does not convey production hydrocarbons flowing from a subsea well, any tubes within the carrier pipe have an inner diameter of no more than 70mm. Any such tubes contain only a control fluid or a service fluid for supporting production of hydrocarbons. Each spacer comprises a stack of blocks and an opening that extends along a longitudinal axis through the spacer at an interface between abutting blocks of the stack. Each opening receives a respective elongate functional element of the umbilical.

Calculation of the authentication code comprises a cryptographic calculation based on a first hash value determined from the first data block and a second hash value determined from the second data block. A hash value cache is provided to store hash values determined from data blocks retrieved from the protected area of the memory. When the first data block and its associated authentication code are retrieved from memory, a lookup for the second hash value in the hash value cache is performed, and a verification authentication code is calculated for the memory granule to which that data block belongs.
