Fighting API Compatibility On Fluentd Using "Black Magic"SATOSHI TAGOMORI
The document discusses Fluentd's changes to its plugin API between versions 0.12 and 0.14. In 0.14, the API was overhauled to separate entry points from implementations and introduce a plugin base class to control data and control flow. A compatibility layer was added to allow most 0.12 plugins to work unmodified in 0.14 by handling calls to overridden methods. However, plugins that override certain methods like #emit may cause errors due to changes in how buffering works.
This document discusses Zabbix, an open source monitoring software, and its job scheduling capabilities using HyClops. It also talks about TIS's support for open source software and monitoring infrastructure using Zabbix. The presentation provides an overview of Zabbix's features for monitoring servers, networks, databases and applications using agents. It also describes how Zabbix uses APIs to integrate with external systems for monitoring.

Vuex is used to manage state in a Vue application. Components dispatch actions that commit mutations to update the central state object. Computed properties are used to retrieve parts of the state and watch for changes. Two-way bindings with v-model trigger mutations to update state values. Maps are used to generate computed properties for multiple state properties.
This document defines a Puppet class called "app" that includes classes for development packages and Ruby. It checks that port 80 is listening and that the app server returns a response including the word "Hello" when requesting the HTTP URL.
The document describes various Git commands and workflows for managing branches and changes. It shows how to clone a repository, check out a topic branch, commit changes, rebase and merge branches, resolve conflicts, revert commits including merges, and cherry-pick commits. Key steps include checking out branches, committing code, pulling latest changes, rebasing and merging branches, resolving conflicts, and reverting or cherry-picking specific commits.
