Abstract: An approach is provided that receives, over a computer network, transaction data from a number of clients that are running an app. The approach generates association rules by inputting the transaction data to an association rule learning algorithm, such as an Apriori algorithm. Each association rule is based on a user transaction pattern and a desired result, and each association rule includes a generated confidence value that pertains to an expected performance of one of the steps included in the respective association rule. The app is then modified based on an analysis of the generated confidence values, with the app modification being directed towards improving one or more of the confidence values.

Abstract: A method for defending a computing system against ransomware attacks is disclosed. In one embodiment, such a method includes identifying, on a computing system, files to be protected against ransomware attacks. The method appends a public key to each of the files. Upon receiving a request to modify a specific file, the method reads the public key appended to the file, requests an authentication token from a user, and computes a private key associated with the files. The method combines the public key, authentication token, and private key to generate an unlock key. This unlock key is compared to a validation key. The method authorizes modification of the file in the event the unlock key matches the validation key. A corresponding system and computer program product are also disclosed.

Abstract: In deploying a system in a computing environment, before deployment, a deployment engine performs a pre-deployment validation of the system using pre-determined system requirements. When the pre-deployment validation of the system fails, the deployment of the system is terminated. When the pre-deployment validation of the system succeeds, the deployment engine performs the following for each artifact of the system. Before deployment of a given artifact of the system, a pre-deployment validation of the given artifact is performed using pre-determined artifact properties. When the pre-deployment validation of the given artifact fails, the deployment of the system is terminated. When the pre-deployment validation of the given artifact succeeds, the given artifact is deployed. After the deployment of the given artifact, a post-deployment validation of the given artifact is performed using deployment data for the given artifact.

Abstract: Embodiments for leveraging directed acyclic graph (DAG) information to group tasks for execution, by at least one processor. An Input/Output (I/O) cost for each task in a set of tasks determined to be within a same input host set is determined, and tasks within the set of tasks are grouped into task groups according to an applied allocation time. The task groups are launched commensurate with a calculated delay time from each input host set so as to overlap I/O phases and central processing unit (CPU) phases to improve CPU efficiency. The launched task groups are executed by an executor according to the calculated delay time.
