- Start multiple running scripts simultaneously in the terminal and keep running after the terminal session is finished
- This article describes a way to run multiple PHP scripts simultaneously on a Linux server and keep running after the terminal session is over. By creating a separate session using the screen command and then starting the script in parallel within that session, you can ensure that the script continues to run in the background, even if the terminal is shut down or the server is restarted. This approach simplifies the process of managing multiple resident tasks and allows users to view the output of the script at any time.

- Integrating Twig Template in Vue Components: Implementing Strategies and Practices
- This article explores the challenges and solutions for integrating Twig templates in Vue components. Since it is impossible to embed Twig templates into Vue components and render them directly in the client environment, the article proposes two main strategies: one is to completely migrate the logic of the Twig template to the Vue component to implement; the other is to use the backend to render the Twig template, and obtain the generated HTML content through HTTP requests, and then use Vue's v-html directive to load it into the component dynamically, thereby achieving effective collaboration between front and backend templates.

- Shopware 6 Analysis of the 'ad' blacklist mechanism in the generation of media path MD5
- When Shopware 6 generates media file paths, it will process them based on the MD5 hash value, and deliberately replaces the "ad" that appears in the path slice with "g0". This mechanism is designed to avoid the possibility that the ad blocker may misidentify the path containing "ad" as advertising content, resulting in the inability to load media files such as images and ensure the user experience and the integrity of the website content.
