Abstract: In a general aspect, a submersible barge includes a deck having a support surface and an additive manufacturing system. The submersible barge may be deployed on a body of water. The additive manufacturing system is configured to fabricate a cementitious body on the support surface by successively depositing layers of flowable cementitious material on top of each other. The submersible barge also includes a buoyancy system that is configured to lower the cementitious body into the body of water by altering a draft of the submersible barge between first and second drafts. When the submersible barge is at the first draft, the support surface resides above a surface of the body of water. When the submersible barge is at the second draft, the support surface resides below the surface of the body of water.

Abstract: In one general embodiment, a computer-implemented method includes performing a firmware update on a hardware component of a computer system. A hash value associated with the update of the firmware is collected, and added to Platform Control Registers (PCRs) of multiple Trusted Platform Module (TPMs) of the computer system. The hash value is logged in a log file. At a predetermined time, PCR values are received from the TPMs. The PCR values are compared to determine whether all PCR values match. In response to one of the PCR values not matching, a warning is issued.

Abstract: Request flow log retrieval can include extracting one or more keywords from a natural language description of an action, the action being a system response to a user request submitted to a resource-provisioning system during a user session. Request flow log retrieval can also include determining a classification of the action based on a correlation value generated by a classifier model trained using machine learning to classify actions performed by the resource-provisioning system, the classification based on the one or more keywords. Additionally, request flow log retrieval can include automatically identifying a request flow associated with the action based on the classification of the action and returning at least one system log entry corresponding to the request flow.

Abstract: The invention relates to a method for preventing search fraud in a content management system. For an update of a content item of a search index of a search service provided by the content management system ranking metrics are calculated using a set of one or more search queries from a collection of search queries previously received by the search service. At least one statistic is computed using the calculated ranking metrics and compared with at least one statistic provided by a statistics history database. Depending on the result of the comparing, the update of the content item is flagged as fraudulent or as non-fraudulent.

Abstract: A computer-implemented method for consolidating log file entries may be provided. The method comprises receiving a first log file and a second log file, determining a first characterizing feature set of a first log file entry of the first log file and a second characterizing feature set of a second log file entry of the second log file, and determining a correlation factor value of a correlation between the first log file entry and the second log file entry by classifying a relationship of the first log file entry and the second log file entry using the characterizing feature sets. The method further comprises upon determining that the correlation factor value is above a predetermined correlation factor threshold value, determining that the first log file entry and the second log file entry relate to each other and belong to a same action flow.

Abstract: In a method of and system for enforcing authentication strength for remote portlets, a portlet is provided by a producer portal and consumed as remote portlet by a consumer portal. The producer portal defines an authentication strength level requirement for the portlet. A user requests the remote portlet from the consumer portal. The consumer portal authenticates the user with a particular authentication method that implies a particular authentication strength level. The producer portal authenticates the consumer portal with a particular authentication method that implies a particular authentication strength assertion level. The consumer portal requests the portlet from the producer portal with an assertion of the authentication strength level of the user. The producer portal rejects the request from the consumer portal if the authentication strength level of the user is less than the authentication strength level requirement for the portlet.

Abstract: A method and corresponding apparatus are for compressing image data of an image. The method includes splitting the image data into regions, including a first region and a second region. The method further includes determining a first compression scheme to be used in encoding the image data of the first region and a different second compression scheme to be used in encoding the image data of the second region. The method further includes applying the first compression scheme to the image data of the first region and the second the compression scheme to the image data of the second region. For each region, the determining and the applying are iteratively performed to yield first resulting compressed region data for the first region and second resulting compressed region data for the second region.

Abstract: A client system is controlled for accessing protected remote resources via a Web Application using a rewriter proxy that supports relative URLs. In one configuration, the Web application can be a Portal application. A URL utility module can be provided for a rewriter proxy that splits an absolute URL into a base part (the URL string up to the resource) and the resource part. A security module computes an authentication identifier for the base part. This can occur by applying a secure hash algorithm and/or secret key. The URL utility module then constructs the rewritten URL by concatenating the URL encoded base part, the authentication identifier, and the resource part as separate path elements.
