Abstract: A computer system is configured to override an original behavior of a function at runtime. Overriding the original behavior of the function at runtime includes identifying an override behavior for overriding the original behavior of the function, and encoding replacement code based on the override behavior. Further, a size of the replacement code is identified, and a first memory address of the function where code of the function is stored is also identified. The computer system then copies a block of code having the size of the replacement code from the first memory address to a second memory address, and copies the replacement code to the first memory address. After the replacement code is executed, copying the block of code stored at the second memory address back to the first memory address, restoring the code of the function.

Abstract: In an example embodiment, an iterative process is used to calculate the number of parallel work processes to set for a computer system. Specifically, an execution unit is started and the execution time for that execution unit is measured. This execution time for the single execution unit is called “unit time.” Then a fixed number (e.g., 20) of execution units are started, and the execution times of each are measured. If the execution time consumption of each of the execution units is lower than some fixed threshold percentage of the unit time (e.g., 120%), then this means that the maximum parallel processing capacity is higher than the fixed number of execution unit. Then more execution units can be added and the process repeated until the execution units' execution times exceed that fixed threshold percentage.

Abstract: A method and system for artificial intelligence (AI) powered contextual recommendations of digital content. The method includes receiving an input, associated with a virtual environment, at a client device. The method also includes generating image embeddings based on an image representation of the virtual environment.

The method also includes determining a context of the virtual environment based on the one or more digital content. The method also includes determining a context of the virtual environment based on the one or more digital content and generating a recommendation based on the context.

Abstract: Disclosed is a Flammlina filiformis with a fruiting body of a golden cap and a white stipe. The Flammlina filiformis has a strain number of “Jin Jin No. 1” and has been preserved on Jun. 16, 2022 at the China General Microbiological Culture Collection Center with a registration number of CGMCC No. 40222. Colors of the cap and the stipe of the Flammlina filiformis “Jin Jin No. 1” have obvious differences. Compared with a parent white Flammlina filiformis strain F0012, the Flammlina filiformis “Jin Jin No. 1” has an equivalent average yield, an initial harvest period 1-2 days late, and a golden cap.

Abstract: Methods and systems are provided for an improved cluster-based network architecture. According to one embodiment, an active connection is established between a first interface of a network device and an enabled interface of a first cluster unit of an HA cluster of network security devices. The HA cluster is configured to provide connectivity between network devices of an internal and external network. A backup connection is established between a second interface of the network device and a disabled interface of a second cluster unit. While the first cluster unit is operational and has connectivity, it receives and processes all network traffic from the network device that is destined for the external network. Upon determining the first cluster unit has failed or has lost connectivity, then all subsequent network traffic originated by the network device that is destined for the external network is directed to the second cluster unit.
