Abstract: A software and hardware facility persistently maintains metrics on directories at different levels within a tree of a filesystem. The facility hierarchically aggregates attributes of files contained by directories and stores them as metric values in each directory within a tree. The stored values represent summed or otherwise aggregated data from the descendant directories and files. The metric values represent aggregated attributes such as checksums, MIN and/or MAX aggregates, sameness bits, bloom filter aggregates, queryable user tags, moving average aggregates, b-tree aggregates, etc. The facility provides mechanisms for efficiently sampling activities performed by the filesystem and visually representing these activities.

Abstract: Methods and systems for encrypting data are disclosed. A circuit uses a white noise generator to capture a random string of bits as an encryption key. The encryption key is generated at a central server and is provided to a subscriber on a physical memory device. The subscriber uses the encryption key to encrypt a source data file. The encrypted data file is sent to the central server, which uses the encryption key to decrypt the encrypted data file and to recover the source data file. The file name for the source data file may be encrypted into the encrypted data file and a new name assigned to the encrypted data file. A random number index may be used to identify the starting point of the encrypted file.

The second body has a release recess operable with the release ball to disengage the hinge ball and alternately couple and release the first body and the second body based on a relative position between the first body and the second body.

Abstract: An apparatus includes acoustic equipment and an enclosure to support the acoustic equipment. The enclosure includes a front cover member, a middle cover member, a back cover member, and a hinge to connect the front cover member to the back cover member. The hinge enables the movement of the front cover member and the back cover member between an open position and a closed position. The middle cover member is disposed between the front cover member and the back cover member, with the middle cover member being connected to the hinge to enable movement of the middle cover member and the back cover member between an open position and a closed position. The enclosure further includes a first latch configured to releasably secure the middle cover member to the back cover member, and a second latch configured to releasably secure the front cover member to the back cover member.

Abstract: A tile saw includes a base, a frame assembly disposed on the base, a first rail disposed on the frame assembly, the first rail having a longitudinal axis. A table is slidingly disposed on the first rail and a support assembly is disposed on the base. A fence assembly is attachable to the table and has a first fence and a second fence for contacting the workpiece. The second fence is pivotably attached to the first fence and pivotable about a substantially horizontal axis. A saw assembly is supported by the support assembly and includes a motor, and a cutting wheel driven by the motor.

Abstract: A retractor assembly for a cylindrical lockset comprises inner and outer retractors. Each of the retractors has a cam engaging surface to convert rotary motion from the inside door handle into linear latch-retracting motion. Inner and outer spindles having retractor activation cams are configured to bear upon cam surfaces of the inner and outer retractors to retract the latch. When the inner door handle is operated, the inner retractor acts directly upon the tailpiece of the latch bolt assembly to retract the latch. When the outer door handle is operated, the outer retractor presses on the inner retractor, causing it to retract the latch. If there is an attack, a blocker assembly engages with members formed in the outer retractor to render the outer retractor inoperative to move into a latch-retracting position without interfering with operation of the inner retractor to move into a latch-retracting position.
