Added custom multi-selectable fields to the ZenTao BUG page

At present, the fields on the ZenTao BUG page are relatively common. If you need more fields, you need to open a second version of ZenTao. The following is an example of adding [Discovery Stage] and [Environment] custom fields: 1. Execute this SQL in the database Enter the ZenTao initial page, select [Database Management], enter […]

How to understand and select optimistic locks and pessimistic locks during back-end development?

The author was asked this practical question when participating in a soft opening interview at a bank, so I came here to learn and summarize it. To get straight to the point, when choosing between pessimistic locks and optimistic locks, you need to consider the specific application scenarios: Pessimistic locking is suitable for scenarios where […]

BGP path selection–Next_Hop

Next_Hop attribute The Next_Hop attribute records the next hop information of the route. The next hop attribute of BGP is different from that of IGP and is not necessarily the IP address of the neighbor device. Normally, the Next_Hop attribute follows the following rules: When the BGP Speaker advertises a route to an EBGP peer, […]

Depth-first search of directed graphs and dynamic selection algorithm of adjacency matrix

Introduction In graph theory, a directed graph is a graph structure with directional relationships between nodes. In practical applications, we often need to represent and operate directed graphs. In order to improve efficiency, we can dynamically select appropriate data structures for representation based on the size of the graph and the frequency of operations. Adjacency […]
