Abstract: The SUPVERT rack is a multipurpose storage rack for rigid stand up paddleboards. The vertical, parallel tracks facilitate SUP board display and storage in the most space efficient manner. The SUPVERT rack does not contain any full height partitions between boards; rather it uses stacked parallel tracks for spacing, thereby drastically reducing the overall footprint. The versatility of the rack allows it to be used for static displays, freight crates, or mobile SUP business operations.

Abstract: A method described herein involves various operations directed toward network security. The operations include accessing transaction data describing network traffic associated with a web server during an interval. Based on a count of new transactions involving an online entity during the interval according to the transaction data, a short-term trend is determined for the online entity. The operations further include applying exponential smoothing to a history of transactions of the online entity to compute a long-term trend for the online entity. Based on a comparison between the short-term trend and the long-term trend for the online entity, an anomaly is detected with respect to the online entity in the network traffic associated with the web server. Responsive to detecting the anomaly, an access control is implemented between the online entity and the web server.

Abstract: A system has a memory programmed with multiple firmware images each having an associated distinct entry point, a processor, a writable hardware register, and a controller external to the processor that, prior to each reset of a sequence of resets of the processor, reads the entry point of a firmware image from the hardware register and causes the processor to begin fetching instructions at the entry point read from the hardware register. The firmware images include boot, mission mode, and at least one other firmware image. The memory may be writeable with a modifiable version of a post-production mission mode, debug, prototype, or patched ROM firmware image. A second controller writes a second entry point to the hardware register prior to an initial reset such that the external controller reads the second entry point and causes fetching instructions at the second entry point rather than the initial entry point.
