A non-limiting example computer-implemented method includes receiving a function of a source platform. The function can include a plurality of fields. An initial vector is constructed for each of the plurality of fields. The initial vector encodes a value of the respective field according to an encoding rule. The initial vectors are merged into a single final vector and the final vector is classified into one of a plurality of system function families of the source platform. A vector of a target platform at a minimum distance to the final vector is identified and an assessment is provided that includes a difficulty in porting a project comprising the function between the source platform and the target platform based at least in part on the minimum distance.

Abstract: Examples described herein provide for determining a recipe for identifying from which buckets integrated circuit chips are taken to form units of a multi-chip apparatus. In an example, a method uses a processor-based system and uses a Markov Decision Process. Buckets are defined based on respective characteristics of manufactured chips. Each of the manufactured chips is binned into a respective one of the buckets based on the characteristic of the respective manufactured chip. A recipe for identifying from which of the buckets to take one or more of the manufactured chips to incorporate into respective ones of the units of the multi-chip apparatus is generated.

Abstract: Aspects include generating a matrix based on a first sample of source code. Each cell in the matrix can correspond to a unique element in the source code. Each unique element can be encoded to a predetermined value according to an encoding rule. A first waveform is generated by combining a left-side curve and a right-side curve. The left-side curve encodes a first position of non-zero cells in each row of the matrix and the right-side curve encodes a last position of non-zero cells in each row of the matrix. A second sample of source code is identified that matches the first sample of source code based on a comparison of the first waveform to a second waveform constructed from the second sample of source code.

Abstract: Systems and methods for managing demand for virtual computing resources are disclosed. A demand forecasting service can obtain and analyze historical demand data for purposes of predicting future demand. The analysis includes identifying untargeted demand corresponding to requests for virtual machine instances that can be fulfilled by any availability zone of a set of zones. The demand forecasting service may provide predictions of future demand including information regarding future untargeted demand, thereby enabling efficient allocation of computing resources among various availability zones to meet the future demand.

Abstract: Systems and methods are described to enable assessment of demand for points of presence (POPs) within a content delivery system, independent of the capacity of such POPs. The content delivery system can utilize load balancing technology to distribute user requests for content to various POPs, based at least partly on the capacity of the POPs. Because load balancing generally occurs prior to a user's connection to a POP, the monitored load of individual POPs may not accurately reflect user demand for the individual POPs services. Accordingly, systems and methods are disclosed to correlate pre-load-balancing requests, such as DNS requests, with post-load-balancing demand levels. Thereafter, the determined correlation can be utilized to assess user demand for individual POPs, independent of the observed load on that individual POP. In some instances, POPs or other network components can be clustered to determine capacity-independent demand for a collection of POPs.

Abstract: Systems and methods are directed to migrating virtual machine instances between equipment racks of, for example, a data center such that one or more of the equipment racks can be emptied of all active virtual machine instances. Power then can be reduced or completely shut off the racks emptied of their active virtual machine instances. Cooling for such racks also can be reduced. Energy and costs to operate and cool the racks thus are saved. Such techniques are particular beneficial during periods of reduced network activity (e.g., at night and on weekends). Also, all virtual machine instances running in a particular room of a data center can be migrated to server computers running elsewhere to thereby permit utilities (e.g., power, cooling) to the room to be reduced or shut down completely.

Abstract: A method and system for increasing the expected availability of fast-delivery offers to customers. A method may include identifying a total number of units of a plurality of items to be stored in one or more fulfillment centers. In some cases, the items may be a product or a group of products. The method may also include receiving an order forecast of expected orders for each of the plurality of items and determining, for each of the plurality of items, a portion of the expected orders that is expected to be fulfilled by the one or more fulfillment centers. The method may then include calculating based, at least in part, on the total number of units, the order forecast, and the portion of the expected orders, a target inventory of each of the plurality of items that increases an expected availability of a given delivery offer to future customers.

Abstract: In various embodiments, approaches for the placement of inventory in a materials handling facility are described. A virtual representation of a plurality of storage locations in a materials handling facility is maintained in a computer system. Each one of a plurality of inventory items is assigned to a corresponding storage location in the virtual representation. A first portion of the inventory items is stocked, and a second portion of the inventory items is unstocked. Each of the assignments is associated with a profit value. An event related to a change in state of the materials handling facility is input into the computer system. Each one of the second portion of the inventory items is reassigned in the computer system to a corresponding storage location in the virtual representation.

Abstract: A communication system is provided that alerts a public safety officer to missed Push-to-Talk (PTT) group calls. The communication system allows a public safety officer's radio to record a last stop working time. A public safety network then can search a missed call list associated with the public safety officer and automatically push a notification of missed PTT group calls to the public safety officer's radio when the radio re-joins the public safety network. Based on the notification, the public safety officer can choose to review or replay any missed calls to avoid missing important information.

A subscriber unit and radio communication system are also disclosed.
