Windows下Rust环境安装推荐使用Visual Studio Code。方案一：先安装Microsoft C++ Build Tools，并手动添加环境变量；再使用rustup-init安装Rust。方案二：使用RustRover，在其中新建项目自动安装Rust环境。安装完成后，使用`rustc -V`和`cargo -V`命令验证安装是否成功。

作者在尝试了 OpenWrt 和爱快等软路由系统后，最终选择了 iStoreOS。 爱快系统功能有限，OpenWrt 虽然强大但配置复杂且出现网络问题。iStoreOS 的简洁界面、易用性以及丰富的插件支持，特别是包含 1panel，吸引了作者。作者认为 iStoreOS 对新手和进阶用户都非常友好，易于安装和配置，功能全面，是值得推荐的软路由系统选择。

This bash script creates and activates a swap file on a Linux system. It defaults to a 4GB swap file (/usr/swap/swapfile), but this size can be adjusted via a command-line argument. The script uses `dd` to create the file, `mkswap` to format it, and `swapon` to activate it. While the script includes commented-out lines for setting the swap file to activate on boot via `/etc/fstab`, this feature is not enabled by default. The script also displays the size of the created swap file using `du`.

This article details setting up HTTPS with two-way authentication for Tomcat using Java. It provides Linux and Windows scripts for generating server and client certificates using keytool. The process involves creating a server keystore, a client keystore and certificate, and importing the client certificate into the server keystore. Tomcat configuration involves modifying `server.xml` to enable HTTPS with `clientAuth="true"` and optionally configuring `web.xml` for HTTP to HTTPS redirection. Finally, the article explains client-side certificate installation and troubleshooting, specifically addressing "Invalid keystore format" errors by ensuring consistent Java versions between certificate generation and Tomcat.

本文介绍了如何在Java游戏开发中添加背景音乐和音效。文章首先介绍了音频资源的存放路径（assets/music和assets/sounds），并说明了使用MP3和WAV格式。然后，重点讲解了如何在游戏启动后循环播放背景音乐，以及在玩家与目标碰撞时播放音效。代码示例展示了如何在FXGL引擎中实现这些功能，包括重写onPreInit方法和利用CollisionHandler处理碰撞事件。文章还包含了项目目录结构图和完整代码，方便读者参考。最后，文章提供了其他相关文章链接，方便读者进一步学习。
