Abstract: The present invention provides for the manipulation of carbon flux in a recombinant host cell to increase the formation of desirable products. The invention relates to cellulose-digesting organisms that have been genetically modified to allow the production of ethanol at a high yield by redirecting carbon flux at key steps of central metabolism.

Abstract: Determining which snapshot deltas tend to occur in: (i) healthy virtual machines (VMs) that have been subject to an attack yet remained healthy, and/or (ii) unhealthy VMs that have apparently been adversely affected by an attack. Snapshot deltas that occur in at least some (or more preferably all) of the healthy VM subset provide information about software changes (for example, updates, configuration changes) that may be helpful. Snapshot deltas that occur in at least some (or more preferably all) of the unhealthy VM subsets provide information about software changes (for example, updates, configuration changes) that may be unhelpful.

Abstract: Embodiments of the present invention provide an approach to repair vulnerabilities (e.g., security vulnerabilities) in images (e.g., application images) in a networked computing environment (e.g., a cloud computing environment). Specifically, an image is checked for vulnerabilities using a database of known images and/or vulnerabilities. If a vulnerability is found, a flexible/elastic firewall is established around the image so as to isolate the vulnerability. Once the firewall has been put in place, the vulnerability can be repaired by a variety of means such as upgrading the image, quarantining the image, discarding the image, and/or generating a new image. Once the image has been repaired, the firewall can be removed.

Abstract: A system, a computer readable storage medium, and a method for determining a suggested component restart order in a computer system on a basis of one or more heuristic analyses of a plurality of input data. The method can include performing one or more sort or merge orders after one or more of each heuristic analysis, combining the one or more sort orders according to a weighting algorithm, generating a recovery dependency graph between each of the components of the computer system, and presenting the recovery dependency graph.

Abstract: Methods, systems, and computer program products for providing fault injection to Cloud-provisioned machines are provided herein. A method includes determining one or more fault conditions to be associated with a fault injection implementation based on one or more parameters associated with a request for the fault injection implementation; generating a specification for a lifecycle of the fault injection implementation based on the one or more fault conditions; and executing the fault injection implementation in a target system, wherein said executing comprises effecting the lifecycle of the fault injection implementation according to the generated specification.

Abstract: Embodiments of the disclosure relate to controlling access to a mobile device with a paired device. Aspects include pairing the paired device with the mobile device and defining a security profile for the mobile device. Aspects also include receiving a user access request for a desired action via the mobile device and determining signal strength between the paired device and the mobile device. Aspects further include executing the desired action based on a determination that the signal strength is greater than a threshold in the security profile for the desired action.

Abstract: Embodiments include method, systems and computer program products for searching a social network for media content. Aspects include receiving a query for media content related to a topic from a user, identifying a plurality of content items associated with the topic and determining a quality score for each of the plurality of content items. Aspects also include providing a subset of the plurality of content items to the user, wherein the subset is selected based on the quality score and updating the quality score of one or more content items in the subset based on a behavior of the user in viewing the subset of the plurality of content items.

Abstract: A mechanism is provided for identifying patterns of a set of software applications instances from their documents. The computer-implemented method begins with constructing different attribute vector types using a knowledge ontology. The knowledge ontology captures semantics based on keywords associated with resource attributes derived from one or more documents related to at least a portion of these software application instances. A knowledge base is built from the attribute vector types and the documents of these application instances. These are merged into the knowledge base with the knowledge base previously built from previous software application instances. Analytics are performed on the knowledge base to identify at least one of common patterns of deployments, configurations, or other attribute vector types, or a combination thereof.
