Abstract: A method, computer program product and system are provided for preloading debug information based on the presence of incremental source code files. Based on parsed input parameters to a source code debugger, a source code repository and a local storage area are searched for an incremental file. In response to the incremental file being located, a preload indicator in the incremental file, which is a source code file, is set. Based on the preload indicator being set, debug symbol data from the incremental file is merged to a preload symbol list. In response to receiving a command to examine the debug symbol data from the incremental file, the preload symbol list is searched for the requested debug symbol data.

Abstract: This disclosure provides a computer-implemented method. The method may comprise obtaining a character of first-direction communications and a character of second-direction communications in a network environment, the first-direction communications being network communications from a first node to a second node, and the second-direction communications being network communications from the second node to the first node. The method may further comprise determining a dependency between the first node and the second node based on the character of first-direction communications and the character of second-direction communications, the dependency between the first node and the second node indicating whether the first node depends on the second node or the second node depends on the first node.

Abstract: Embodiments of the present disclosure relate to methods, systems, and computer program products for managing a distributed system. In one embodiment, a computer-implemented method is disclosed. In the method, packets that are to be transmitted among a group of nodes in a distributed system may be collected into a queue of packets, here a packet in the queue is associated with a source node and a destination node in the group of nodes. A snapshot in the group of snapshots may be obtained from a node in the group of nodes, therefore a group of snapshots may be obtained from the group of nodes. A snapshot of the distributed system may be generated based on the queue of packets and the group of snapshots. In other embodiments, a computer-implemented system and a computer program product for managing a distributed system are disclosed.

Abstract: Methods and apparatus are described for validating files associated with content items. The validation can be performed according to feedback statistics including failure rates pertaining to the content items.

Abstract: Embodiments of the invention provide methods, systems, and articles for displaying objects in images, videos, or a series of images with WYSIWYG (what you see is what you get) effects, for calibrating and storing dimensional information of the display elements in a display system, and for constructing 3-dimensional features and size measurement information using one camera. Displaying merchandises with WYSIWYG effects allows online retailers to post vivid pictures of their sales items on the Internet to attract online customers. The processes of calibrating a display system and the processes of constructing 3-dimensional features and size measurement information using one camera are applications of the invention designed to achieve desired WYSIWYG effects.
