Abstract: The technology provides for allocating an available resource in a computing system by bidirectional communication between a hypervisor and a container scheduler in the computing system. The computing system for allocating resources includes one or more processors configured to receive a first scheduling request to initiate a first container on a first virtual machine having a set of resources. A first amount of resources is allocated from the set of resources to the first container on the first virtual machine in response to the first scheduling request. A hypervisor is notified in a host of the first amount of resources allocated to the first container. A second amount of resources from the set of resources is allocated to a second virtual machine in the host. A reduced amount of resources available in the set of resources is determined. A container scheduler is notified by the hypervisor for the reduced amount of resources of the set of resources available on the first virtual machine.

Abstract: A tutorial system presents a tutorial comprising a series of steps for building a computing system and testing successful completion of at least one of the steps. The computing system comprises a programmable controller and at least one hardware component. The tutorial system is coupled to the target computing system via a connection. The tutorial system may present one or more programming steps for the user to enter and load particular programming to the controller. The tutorial system may further present one or more physical steps for the user to physically configure a particular hardware component, such as physically configuring connections or wiring between the particular hardware component and the controller and/or another hardware component of the computing system. The tutorial system directly tests successful completion of a physical step or a programming step through values received from the computing system via the connection.
