#other This collection is a big set of open-ended questions about backend development, covering everything from code design and databases to security, teamwork, and even some fun, creative questions. The main idea is not to test for right or wrong answers, but to start conversations that help you understand how someone thinks, solves problems, and works with others. By using these questions, you can quickly see what topics a candidate knows well and how they approach new challenges, which helps you find the best fit for your team and project[2][3][4]. The benefit is that you get a clearer, more honest picture of a person’s skills and style, making it easier to choose the right developer for your needs. https://github.com/arialdomartini/Back-End-Developer-Interview-Questions

vibe coding 了个端口敲门工具,欢迎体验 knock-proxy 是一个端口敲门 TCP 转发工具。服务端用防火墙默认 DROP 公网 TCP 端口;客户端先发送 knock ,服务端验证后临时放行来源 IP ,然后客户端连接同一 TCP 端口,完成 HMAC-SHA256 二次认证并转发到本机 upstream 。 适合隐藏 SSH 、RDP 、数据库管理端口、Web 管理后台等 TCP 服务。 项目地址 <https://github.com/ming79486/knock-proxy> via V2EX 分享创造 标签: #端口#TCP#knock ⚡️探索号频道 ⚡️探索者频道 ⚡️探索者交流群 ⚡️ Youtube 频道:科技探索者 每天推荐有趣内容,欢迎订阅、转发。
