Abstract: A request to perform a compute task is received. A service to perform at least a portion of the compute task is identified, wherein the identified service is associated with a field-programmable gate array that has been programmed to perform at least the portion of the compute task. The identified service to perform at least the portion of the compute task of the request is invoked. At least the portion of the compute task is executed using the field-programmable gate array.

Abstract: A user identifies products offered by the user to an online system. The online system identifies a product offered by the user in an image by applying a identification model to the image. If the online system identifies a product in the image with at least a maximum confidence value, the online system automatically tags the post with metadata about the product or suggests a tag to the user. If an object in the image could be one of multiple products, the online system identifies the multiple products to the user, which may be ordered based on confidences of matching the object, allowing the user to select which product is in the image. If the unlisted identifies a product in the image with less than a minimum confidence value, the online system identifies the user's offered products and suggests that the user select a product.

Abstract: Examples, methods and systems described herein may include determining, by a payment processing system, whether a second payment mechanism may be used to perform a payment transaction when a first payment mechanism is preferred and/or when the first payment mechanism has failed. Determining to use the second payment mechanism can be based on (i) an analysis of a communication status indicator received from a point-of-sale (POS) terminal that indicates which payment mechanisms are capable of communicating with the POS terminal, (ii) data received from the POS terminal that is associated with a read of a payment object, and/or (iii) an allowance criterion.

Abstract: In some examples, methods and systems may institute technical fallback by determining, by a payment processing system, and based on analysis of the communication status indicator and the data obtained when a magnetic stripe of the payment object is introduced in magnetic stripe object reader, whether the payment object was swiped while an EMV object reader was communicatively coupled to the POS terminal. If the magnetic stripe of the payment object was swiped while the EMV object reader was connected to the POS terminal, the payment processing system extracts a transaction count indicating a number of times the customer has attempted to insert a chip of the payment object into the EMV object reader prior to swiping magstripe. By comparing the transaction count with a threshold count, the payment processing system authorizes the payment transaction as a technical fallback transaction if the transaction count is greater than the threshold count.
