Systems and methods for write protecting foundation fieldbus linking devices
Systems and methods for write protecting Foundation Fieldbus linking devices are described. A message output by an external system for communication to a Foundation Fieldbus linking device may be received by a gateway device. The linking device may be identified by a virtual address included in the received message. The gateway device may determine whether the message includes a command to write data to the linking device or a Foundation Fieldbus device connected to the linking device. If it is determined that the message does not include a command to write data, then the gateway device may direct communication of the message to the linking device. If, however, it is determined that the message includes a command to write data, the gateway device may generate an exception for preventing the requested write operation. |

Managing risk in resource over-committed systems
Risk associated with over-committing shared resources is determined. In response to receiving a request to provision a new workload, a candidate mix of virtual machines is selected from plurality of virtual machines already running on a cloud infrastructure. A utilization profile is then created for an aggregate behavior of the candidate mix of virtual machines and a new virtual machine running the new workload. A risk inherent in over-commitment if the new workload is grouped with the candidate mix of virtual machines is determined, and whether that risk is acceptable. If the risk is acceptable, the new workload is provisioned by over-committing the candidate mix of virtual machines with the new virtual machine running on the cloud infrastructure. |

Monitoring the distribution of software
A computer implemented method to monitor the distribution of software to computers on a network is provided. The network has a data source, for example a systems management tool, which stores data relating to downloads of software. It is desirable for the purpose of operating the network economically to monitor the distribution of software to users. The systems management tool is accessed to determine the number of the computers on the network which have received a particular item of software. That number is compared with a threshold number which is small compared to the number of computers on the network. If the number is less than the threshold that is taken as an indication that the particular item of software has been distributed to the computers by a download as a result of one or more individual requests by users of the computers. Monitoring such indications can be used to estimate the cost of dealing with individual requests and that provides information for assisting a decision to provide a portal for making software available to users. Such an indication may be used to automatically make the software available on a portal to be downloaded by other users, if such a portal is provided. |

Effectively managing configuration drift
Configuration drift refers to changes made over time that cause a computer or service to deviate from a desired configuration. Configuration drift of a group of machines can be managed by defining configuration intent. Intent is defined by defining a configuration baseline comprised of a collection of related configuration rules. Configuration rules include settings, and targets which can be any managed entity that enables reporting of non-compliance at a more granular level. A configuration baseline can be completed by reading configuration rules from one or more well-configured computers. Configuration drift is assessed by comparing actual values to the configuration baseline values and is reported at a managed entity level instead of at a machine level. Remediation, returning the computer to a state of compliance with the configuration baseline, can be performed on demand. Remediations performed over time are retained and applied to a new instance of the service to eliminate configuration drift on the new instance. |

Elimination of duplicate objects in storage clusters
Digital objects within a fixed-content storage cluster use a page mapping table and a hash-to-UID table to store a representation of each object. For each object stored within the cluster, a record in the hash-to-UID table stores the object's hash value and its unique identifier (or portions thereof). To detect a duplicate of an object, a portion of its hash value is used as a key into the page mapping table. The page mapping table indicates a node holding a hash-to-UID table indicating currently stored objects in a particular page range. Finding the same hash value but with a different unique identifier in the table indicates that a duplicate of an object exists. Portions of the hash value and unique identifier may be used in the hash-to-UID table. Unneeded duplicate objects are deleted by copying their metadata to a manifest and then redirecting their unique identifiers to point at the manifest. |

Intelligent deduplication data prefetching
Deduplication dictionaries are used to maintain data chunk identifier and location pairings in a deduplication system. When access to a particular data chunk is requested, a deduplication dictionary is accessed to determine the location of the data chunk and a datastore is accessed to retrieve the data chunk. However, deduplication dictionaries are large and typically maintained on disk, so dictionary access is expensive. Techniques and mechanisms of the present invention allow prefetches or read aheads of datastore (DS) headers. For example, if a dictionary hit results in datastore DS(X), then headers for DS (X+1), DS (X+2), DS(X+read-ahead-window) are prefetched ahead of time. These datastore headers are cached in memory, and indexed by datastore identifier. Before going to the dictionary, a lookup is first performed in the cached headers to reduce deduplication data access request latency. |

The method continues with the processing module dispersed storage error encoding at least a portion of the data to produce a set of encoded data slices and sending the set of encoded data slices to the DSN memory for storage therein. |

DSL system training
Existing and future standardized VDSL2 and other systems can be integrated into and used with a vectored DSLAM or other vectored or non-vectored DSL system, without a new user disrupting service to other users in the same or a nearby binder, in some cases by using transmit power, CARMASK and/or PSDMASK DSL capabilities to reduce both downstream and upstream training-signal levels so that training of a new DSL line is non-disruptive, despite a lack of knowledge of the pre-existing binder. For vectored systems, the crosstalk from that tone can be observed, learned and then added to the vectoring system so that any subsequent excitation on that tone would be eliminated by vector processing. A second tone then can be added in the same way, etc. In non-vectored DSLs that might be operating in a binder or line set, once these non-vectored lines are observed to be present, a vectored line set controller, such as a DSL optimizer, then can anticipate the potential interference from such non-vectored lines. |

For X-ray tubes of the rotary-anode type for generating a fan beam of X-rays, compensation is afforded for system-related disturbances of the focal spot position on a target area of the rotating anode, and particularly for the anode wobble in an X-ray tube, which occurs as a periodically wobbling inclination angle of the anode disk's rotational plane with respect to an ideal rotational plane, the latter being oriented normal to the rotational axis of the rotary shaft on which the anode disk is inclinedly mounted due to an inaccuracy during its production process.

The method includes: performing an emitted energy decrease on resource elements in a current cell that have a same time-frequency location as part or all of resource elements where a reference signal of a neighboring cell is located; obtaining an emitted energy parameter of an energy non-decreased resource element (NRE) in the current cell according to a decreased amount of emitted energy of an emitted energy decreased resource element (DRE); and notifying the emitted energy parameter of the NRE to a user equipment (UE). According to embodiments of the present invention, the waste of emitted energy may be avoided, the emitted energy of part of REs is increased, and further, the signal to interference plus noise ratio (SINR) and throughput of service data may be increased. |
