Pylets is a fast, lightweight, aspect-oriented Web framework built on mod_python and Apache. It uses Apache logs (and more Apache configuration in the future.) It can use Python objects, packages, and modules, or whatever the programmer wants. Pylets are also template-agnostic. With the debug switches off, and caching turned on, Pylets are less than 2x slower than serving static pages. The package comes with ORMit, a lightweight DB-API 2.0 connector-compatible object relational mapper.
OpenVPS is a set of software built on top of the Linux VServer aimed specifically at Web Hosting. It is not another set of kernel patches, but a set of scripts to create virtual servers, collect resource utilization information, and provide an interface to the customer as well as the administrator.
The Darwin Calendar Server is a standards-compliant server that allows multiple users to collaboratively share calendaring information. It provides a shared location on the network to store schedules, and allows users to send each other and manage invitations. In order to provide interoperability with multiple calendaring clients, the server implements the CalDAV protocol, which is an extension of WebDAV, which is in turn an extension of HTTP.
OpenXPKI is a Web and CLI-based enterprise-grade PKI/trust center system (X509 public key infrastructure) complete with CA, Web interfaces, offline support, and support for well established infrastructure components like RDBMS and Hardware Security Modules. Flexibility and modularity are the project's key design objectives. Unlike many other PKI solutions, it offers powerful features necessary for professional environments. However, small scale installations are also targeted by providing quick-start configuration examples that allow you to get a usable PKI running quickly.
The WebReboot Plugin for Nagios is a suite of commands that can be used within Nagios to monitor a server and take corrective action if necessary via the WebReboot line of products. For example, the plugin can be used to alert you if a host is powered down, versus simply not responding to network requests. Likewise, it can be used to reboot a server if a host fails to respond to ping, or to shut down a server when a critical temperature threshold is exceeded. The commands can be mixed-and-matched with all existing Nagios commands, maximizing total network coverage.
Google Sitemap Generator is a tool installed on your Web server to generate sitemaps automatically. Unlike many other third-party sitemap generation tools, Google Sitemap Generator takes a different approach: it will monitor your Web server traffic and detect updates to your Web site automatically.
