A fuel cell based subterranean heater for mineral extraction, in situ decontamination, or other applications. The fuel cells are preferably stacked within a casing which is then inserted into a hole bored, or otherwise formed, into the formation to be heated. Conduits within the casing, and preferably formed by adjacent, aligned holes formed through the plates of the individual fuel cells supply fuel and air and extract exhaust gases. An optional manifold is used to span the overburden without applying heat to it directly. The manifold may also function as a heat exchanger between incoming and exhaust gases. Preferably the fuel cell is fueled by gases produced by the formation and also generates electricity which is available for use or export.

A technique for routing data for improved deduplication in a storage server cluster includes computing, for each node in the cluster, a value collectively representative of the data stored on the node, such as a “geometric center” of the node. New or modified data is routed to the node which has stored data identical or most similar to the new or modified data, as determined based on those values. Each node stores a plurality of chunks of data, where each chunk includes multiple deduplication segments. A content hash is computed for each deduplication segment in each node, and a similarity hash is computed for each chunk from the content hashes of all segments in the chunk. A geometric center of a node is computed from the similarity hashes of the chunks stored in the node.

A novel method and apparatus for one-step linking of membrane permeation of hydrogen to the generation by steam reforming of a methanol-like fuel that comprises bounding a longitudinal flow path of a methanol reformate stream comprising hydrogen, steam and the oxides of carbon and methanol, by a thin palladium-bearing membrane; promoting turbulence in the flow to cause a predominant amount, but not all, of the hydrogen in the stream transversely to permeate the membrane as substantially pure hydrogen passing transversely into a region external to the bounding membrane, thereby simultaneously generating and permeating the hydrogen; and maintaining the hydrogen in the external region at least at atmospheric pressure, but at a lower pressure than the partial pressure of the residual hydrogen in the resulting depleted reformate.

A hash-optimized backup system and method takes data blocks and generates a probabilistically unique digital fingerprint of the content of each data block using a substantially collision-free algorithm. The process compares the generated fingerprint to a database of stored fingerprints and, if the generated fingerprint matches a stored fingerprint, the data block is determined to already have been backed up, and therefore does not need to be backed up again. Only if the generated fingerprint does not match a stored fingerprint is the data block backed up, at which point the generated fingerprint is added to the database of stored fingerprints. Because the algorithm is substantially collision-free, there is no need to compare actual data content if there is a hash-value match. The process can also be used to audit software license compliance, inventory software, and detect computer-file tampering such as viruses and malware.

A client node in a networked printing system outputs in response to a change to an individual print setting input by a user for a print job a real-time update of printing nodes selectable by the user to process the print job. By presenting a user of the client node with a pool of selectable printing nodes that automatically adapts to changes in print settings, inefficiencies of prior processes that require the user to individually assess compatibility of printing nodes with print settings and the pitfalls of prior processes that automatically select a “best fit” printing node that may be compatible with print settings but is undesirable from the user's perspective are avoided. Moreover, by providing a user with immediate feedback on the impact of a change to an individual print setting on the selectable status of printing nodes, the user is able to quickly and accurately determine a combination of print settings and printing node that is desirable from the user's perspective.
