    Nokogiri

    Nokogiri

    Tool to work with XML and HTML from Ruby

    ...It provides a sensible, easy-to-understand API for reading, writing, modifying, and querying documents. It is fast and standards-compliant by relying on native parsers like libxml2 (C) and xerces (Java). Be secure-by-default by treating all documents as untrusted by default. Be a thin-as-reasonable layer on top of the underlying parsers, and don't attempt to fix behavioral differences between the parsers. "Native gems" contain pre-compiled libraries for a specific machine architecture. On supported platforms, this removes the need for compiling the C extension and the packaged libraries, or for system dependencies to exist. ...

    Markdown Any Decision Records

    Markdown Any Decision Records

    Markdown Architectural Decision Records

    ...There is no formal definition of short, medium-sized, and large decision records. The following sections present an example in the context of assertion frameworks for Java. We start with presenting a very short and dense version: It “just” lists the context and problem statement, the available options, and the outcome. For some decisions, these bits of information could not be enough. Therfore, it is possible to “unpack” the decision. This is done in the presented longer version of the ADR.
