Abstract: A ladder having a foot having a plastic body with a recess which receives the end of a first rail and is positioned about and conforms to the web and the first and second flanges of the first rail. The foot has a plastic base having a top side from which the body extends. The base has a front edge. The foot has a metal rail fastener which extends through the body and the rail to attach the body and the rail together. The foot has a pad having a rigid plate with a rubber outer layer surrounding the rigid plate and a pad fastener hole that extends entirely through the rigid plate and rubber outer layer, the outer layer of the pad having a bottom with treads. The foot has a metal pad fastener that extends entirely through the pad and entirely through the base to attach the pad to the base so the rigid plate is between the treads and the base of the shell. A ladder foot. A method.

Abstract: A method, apparatus and machine readable medium are described for reducing power consumption for push messaging. For example, a method in accordance with one embodiment comprises the operations of: registering with a push notification service over a first communication interface, the push notification service to push notifications to the wireless client in response to detected events; detecting that a usable connection to the push notification service may be established over a second communication interface, the second communication interface being an interface which will be operative for reasons other than a connection to the push notification service; responsively disconnecting from the push notification service over the first communication interface and re-connecting over the second communication interface; and temporarily powering down the first communication interface.

Abstract: Techniques for logging performance data are described herein. According to one embodiment, in response to a request for logging performance data, where the request includes a data type indicating a type of performance data and an actual performance data value, a non-linear mathematical operation is performed on the performance data value to generate an index value. The performance data represents a performance measurement of a predetermined operation performed by a data processing system. Thereafter, a value of a data field in a performance data store that stores the performance data is updated based on the type of the performance data and the index value. The value of the data field is updated without having to lock the data field for purpose of simultaneously accesses.

Abstract: A method, apparatus, and computer program product are provided for generating test packets to be used in developing network protocol devices. According to the method of the invention, a first computer system is provided that includes a packet shell generation facility. The packet generation facility includes a generic command language interface mechanism and a packet management function generator. Using the packet shell generation facility test packets are generated for use in testing various aspects of network protocol devices.
