Containerized Java application: Create a Dockerfile, use a basic image such as eclipse-temurin:17-jre-alpine, copy the JAR file and define the startup command, build the image through dockerbuild and run locally with dockerrun. 2. Push the image to the container registry: Use dockertag to mark the image and push it to DockerHub and other registries. You must first log in to dockerlogin. 3. Deploy to Kubernetes: Write deployment.yaml to define the Deployment, set the number of replicas, container images and resource restrictions, and write service.yaml to create

In VSCode, you can quickly switch the panel and editing area through shortcut keys. To jump to the left Explorer panel, use Ctrl Shift E (Windows/Linux) or Cmd Shift E (Mac); return to the editing area to use Ctrl ` or Esc or Ctrl 1~9. Compared to mouse operation, keyboard shortcuts are more efficient and do not interrupt the encoding rhythm. Other tips include: Ctrl KCtrl E Focus Search Box, F2 Rename File, Delete File, Enter Open File, Arrow Key Expand/Collapse Folder.

NumPy is the core library for scientific computing in Python. It is good at handling linear algebra operations and provides efficient ndarray arrays and functions in the numpy.linalg module. 1. Use np.linalg.solve(A,b) to solve the linear equation system Ax=b to obtain the solution vector x; 2. Matrix transposition is implemented through A.T; 3. Matrix multiplication can be used to np.dot(A,B) or A@B; 4. Matrix inverse is calculated by np.linalg.inv(A), and the matrix needs to be reversible; 5. The determinant is given by np.linalg.det(A); 6. The eigenvalue and eigenvector are obtained through np.linalg.eig(A), and the eigenvector has been normalized;
