An antenna structure, an electronic device, and a wireless network system are provided, and relate to the field of antenna technologies. A patch antenna array includes four patch antennas. The four patch antennas are arranged in two rows and two columns. One of the feeding structures is included between two of the patch antennas in each row. One of the feeding structures is included between two of the patch antennas in each column. The feeding structure located between the two patch antennas in each column is connected to the first feeding port, so that the four patch antennas all generate polarization in a first direction. The feeding structure located between the two patch antennas in each row is connected to the second feeding port, so that the four patch antennas all generate polarization in a second direction.

Techniques are described with regard to container image configuration in a computing environment. An associated computer-implemented method includes initializing a container image storage engine associated with a logical tree structure having a plurality of container image nodes, where each of the plurality of container image nodes includes a hash layer array and a hash data array. The method includes building at least one new container image node to incorporate into the plurality of container image nodes. The method further includes applying a software patch to a target container image node among the plurality of container image nodes. In an embodiment, the method further includes starting at least one container based upon a respective container image node among the plurality of container image nodes.

Applying a software patch via a container image storage engine

In an approach for debugging and simulating application runtime execution, a processor loads source code and logs into a debug tool. A processor generates log debug information including a log map, a log variable cross reference table, and a method call stack tree. A processor determines a plurality of log blocks based on log context in the logs and the method call stack tree. A processor maps the source code to the logs for each log block. A processor suggests a starting point and a breakpoint based on the log variable cross reference table and the log blocks. A processor compares a source code variable value to a log variable value and a source code execution path to a log execution path based on the mapping set between the source code and the logs. A processor simulates the source code variable value with the log variable value.

A keyword extraction method is provided. In the method, a candidate keyword set in a target text is obtained by processing circuitry of a server. An extraction degree of the candidate keyword is determined by the processing circuitry based on subject similarity and a text conversion frequency of a candidate keyword in the candidate keyword set. The subject similarity is between the candidate keyword and the target text. The extraction degree indicates a probability at which the candidate keyword used as a keyword matching the target text is extracted. The keyword is extracted by the processing circuitry from the candidate keyword set according to the extraction degree.
