Der interne Dateibetrachter in MC MC ist ein sehr toller Dateibetrachter. Er ist ein großartiges Werkzeug, um nach Wörtern in Dokumenten zu suchen. Ich verwende ihn immer für Dateien im /usr/share/doc-Verzeichnis HTTP und FTP bereitgestellt. Es ist auch als CD-ROM/DVD erhältlich. Das derzeit empfohlene Debian-Werkzeug für Paketmanagement, das all diese Ressourcen nutzen kann, ist das Advanced Pack- aging Tool (APT) 477 Auflistung kritischer Fehler vor jeder APT-Installation apt-file V:17, I:67 89 APT-Paketsuch-Werkzeug - Befehlszeilen-Interface apt-rdepends V:0, I:5 39 rekursive Auflistung von Paketabhängigkeiten

GitHub 上是 Star 数量最多的 Python Web 框架，没有之一。 Flask 是典型的微框架，作为 Web 框架来说，它仅保留了核心功能：请求响应处理 和模板渲染。这两类功能分别由 Werkzeug（WSGI 工具库）完成和 Jinja（模板渲 染库）完成，因为 Flask 包装了这两个依赖，我们暂时不用深入了解它们。 主页 这一章的主要任务就是为我们的程序编写一个简单的主页。主页的 Flask 的依赖 Werkzeug 内置了用于生成和验证密码散列值的函 数， werkzeug.security.generate_password_hash() 用来为给定的密码生成 密码散列值，而 werkzeug.security.check_password_hash() 则用来检查给 定的散列值和密码是否对应。使用示例如下所示： >>> from werkzeug.security 模型类添加 username 字段和 password_hash 字段，分别用来存储登录所需的用户名和密码散列值，同时添加两个方法来实现设 置密码和验证密码的功能： from werkzeug.security import generate_password_hash, check_pass word_hash class User(db.Model): id = db
