Abstract: A web rendering module in the operating system is used to render and display a web page. The web rendering module also generates layout data that describes the position and size of each visual element on the rendered web page. A web editing application uses the layout data to generate a native overlay.

The application displays the native overlay on top of the rendered web page so that each visual element on the web page is aligned with a cell in the native overlay. The cells in the native overlay are transparent so that the rendered web page remains visible to the user, but the native overlay captures any interactions that the user performs. The interactions are then processed to make a corresponding change to the web page.

Abstract: Provided are techniques for handling cache and Non-Volatile Storage (NVS) out of sync writes. At an end of a write for a cache track of a cache node, a cache node uses cache write statistics for the cache track of the cache node and Non-Volatile Storage (NVS) write statistics for a corresponding NVS track of an NVS node to determine that writes to the cache track and to the corresponding NVS track are out of sync. The cache node sets an out of sync indicator in a cache data control block for the cache track. The cache node sends a message to the NVS node to set an out of sync indicator in an NVS data control block for the corresponding NVS track. The cache node sets the cache track as pinned non-retryable due to the write being out of sync and reports possible data loss to error logs.

It then selects the lowest-cost combination of volume and destination pool and then moves the selected volume to the selected pool.
