Abstract: Technologies for cross-device shared web resource caching include a client device (102a) and a shared cache device (102b). The client device (102a) scans for a shared cache device (102b) in local proximity to the client device (102a) and, in response to the scan, registers with the shared cache device (102b). After registering, the client device (102a) requests a cached web resource from the shared cache device (102b). The shared cache device (102b) determines whether a cached web resource that matches the request is installed in a shared cache (102b). The shared cache device (102b) may determine whether an origin of the request matches the origin of the cached web resource. If installed, the shared cache device (102b) sends a found response and the cached web resource to the client device (102a). If not installed, the shared cache device (102b) sends a not-found response and the client device (102a) may request the web resource from a remote web server. Other embodiments are described and claimed.

Abstract: An LED arrangement uses a tapped driver driven by a rectified mains input and placed over a light output surface. There are at least first and second groups of LEDs on the light output surface. The total light output density for the LEDs of the second group (which are turned on for less of the mains cycle) per unit area of the light output surface is greater than the total light output density for the LEDs of the first group per unit area of the light output surface. A fraction of a light emitting surface of the second group (16) of LEDs to a second area (20B) of the light output surface occupied in a macro view by the second group (16) of LEDs, is larger than a fraction of a light emitting surface of the first group (14) of LEDs to a first area (20A) of the light output sur face occupied in a macro view by the first group (14) of LEDs. This means the light output density when averaged over time is made more consistent between the two (or more) groups of LEDs.

Abstract: Technologies for pre-action execution include a client computing device to request a resource from a server and receive content from the server including the requested resource and one or more pre-action hints. Each of the one or more pre-action hints identifies a suggested pre-action to be taken by the client computing device prior to receipt of a corresponding user request to perform the corresponding suggested pre-action. The client computing device determines a likelihood of success of one or more pre-actions based on historical behavior data of a user of the client computing device, wherein each pre-action corresponds to at least one of the one or more pre-action hints. The client computing device selects a pre-action to execute based on the determined likelihood of success of the one or more pre-actions.
