摘要:
Exemplary methods, systems, and products are described that operate generally by moving subroutine return address protection to the processor itself, in effect proving atomic locks for subroutine return addresses stored in a stack, subject to application control. More particularly, exemplary methods, systems, and products are described that write protect subroutine return addresses by calling a subroutine, including storing in a stack memory address a subroutine return address and locking, by a computer processor, the stack memory address against write access. Calling a subroutine may include receiving in the computer processor an instruction to lock the stack memory address. Locking the stack memory address may be carried out by storing the stack memory address in a protected memory lockword. A protected memory lockword may be implemented as a portion of a protected content addressable memory.

A method, system and computer-readable medium for generating, caching and transmitting textual equivalents of information contained in an audio signal are presented. The method includes generating a textual equivalent of at least a portion of a speech-based audio signal in one device into a textual equivalent, storing a portion of the textual equivalent in first device's memory and transmitting the stored textual equivalent to a another device.

To migrate two or more virtual machines in a source hypervisor to a target hypervisor, a list of active and connected virtual machines in the source hypervisor is acquired. Connections between the source virtual machines are rerouted to a buffer so that data flowing between the source virtual machines is captured. The source virtual machines are migrated to a target hypervisor and are connected in the same manner as in the source hypervisor. The buffered data is migrated to the respective migrated virtual machines, and the target virtual machines are activated. The virtual machines can be migrated in order of data flow dependency such that the least dependent virtual machine is migrated first.

A mechanism is provided for performance tuning for software as a performance level service. At the request of a customer, a cloud provider may use a performance tuning component to determine performance parameters to increase performance of an application running on a given hardware platform. The cloud provider may then generate a tuning configuration and associate the tuning configuration with the customer such that when the cloud provider deploys a customer's software to a partition in a host system, the cloud provider sends the tuning configuration with the deployment package. The performance tuning component at the host system then applies the performance parameters in the tuning configuration to increase performance.

A method, apparatus, and computer instructions for authorizing a user to access grid resources. A request is received from the user to access a resource on the data processing system. This request includes a certificate. An authentication process is performed using the certificate when the request is received. In response to successfully authenticating the user in the authentication process, a first host name for the certificate is requested from a trusted source. A reply containing the first host name is received. Access to the resource is provided if the first host name returned by the trusted source matches a second host name for the user from which the request originated.

A method, system and computer program product that creates a transport dictionary, which links preferential terms and definitions to the Multipurpose Internet Mail Extension (MIME) of an outgoing electronic mail (email). Prior to sending a message, users are provided the option of transporting words or acronyms unique to the dictionary of the sender and recipient, which have been utilized in the outgoing email message. Linking dictionary preferences to the outgoing email provides clarity to terms utilized in the email message and decreases the amount of time a responder has to spend skipping, adding, or defining terms that are unique to the incoming MUA dictionary.
摘要:
A cellular telephone system, including: a first cellular telephone for a child; a second cellular telephone for a first relative of the child; and at least a third cellular telephone for at least a second relative of the child; the first cellular telephone including a single button that, when the single button is pushed, automatically activates only one call to a closest one of either (a) the second cellular telephone or (b) a closest one of the at least a third cellular telephone; where closest is measured by at least one of closest geographically, closest by driving time, and closest by driving distance.
摘要:
An aspirator cassette includes a housing having first and second ends sealed off by first and second end caps, respectively. A partition mechanism is enclosed within the housing for dividing its internal volume into first and second regions. First and second fluid flow ports are mounted on the first and second end caps, respectively, to provide fluid flow paths into and from the first and second regions, respectively. When the first region is filled with liquid, its associated first port is connected to a vacuum source for sucking the liquid out of the region, whereby as the liquid is removed, the partition mechanism responds by decreasing the volume of the first region, and increasing the volume of the second region causing its second port to draw a vacuum for sucking fluid from an aspiration device connected to the second port.

An encryption apparatus and method for providing an encrypted file system are provided. The encryption apparatus and method of the illustrative embodiments uses a combination of encryption methodologies so as to reduce the amount of decryption and re-encryption that is necessary to a file in the Encrypted File System in the event that the file needs to be modified. The encryption methodologies are interleaved, or alternated, with regard to each block of plaintext. In one illustrative embodiment, Plaintext Block Chaining (PBC) and Cipher Block Chaining (CBC) encryption methodologies are alternated for encrypting a sequence of blocks of data. The encryption of a block of plaintext is dependent upon the plaintext or a cipher generated for the plaintext of a previous block of data in the sequence of blocks of data so that the encryption is more secure than known Electronic Code Book encryption methodologies.
