Provided are a computing device provided with a DLL injection function and a DLL injection method. When receiving from an operating system notification of whether a target process corresponding to a program ordered by a user to be executed is created, a process creation module of an injection program executes a launcher process to create the target process as a child process of the launcher process and sets the target process to a suspend mode.

The command processor selects the next command for execution based on calculated access times with adjusted priority based on the specified deadline for the command. As the deadline approaches, the priority of the command increases. For high priority data writes as specified by a host, an optimized storage plan is selected as appropriate using the “write-twice cache” (WTC) region, E-region or I-region. |

Preventing database replication conflicts in a distributed environment
A distributed system of data centers is configured to ensure that all data operations involving specific accounts are performed within a given time frame at only one data center. Once a data center has begun accessing data that is associated with an account, all requests to access or manipulate data for that account are redirected to that data center for a period of time. Thus, the data center becomes not only the “owner” of all data associated with the account for that period of time, but also the servicer of all requests associated with the account. The data center then asynchronously replicates changes to the data associated with the account to the other data centers. Since none of the other data centers are permitted to change the data associated with the account, conflicts in the replicated data are minimized. |

Visible light communication with flickering prevention
LEDs that transmit or receive data in a VLC may create a flickering effect which is observed when the human eye is able to perceive the fluctuations of the light intensity in a LED. To prevent flickering, the LEDs may emit light based on a pattern of data and energy intervals. During the data intervals, a LED transmitting a message sends one or more data symbols to receiving LEDs. The receiving LEDs, however, are reversed bias and do not emit light. During the energy intervals, any LED in the VLC system may emit light. Each LED uses the energy interval to compensate for the light transmitted (or not transmitted) during the data interval. The combination of data and energy levels results in an observer seeing light with a constant intensity rather than changing intensity. |
