Plone deployment made easy

This document provides instructions for installing various development tools on Mac OSX, including Xcode, command line tools, Homebrew, Ruby, Python, VirtualBox, Vagrant, Chef, and Ansible. It describes downloading and installing each tool, and in some cases providing additional configuration steps or notes on cleaning up existing installations. The overall purpose is to set up a standard development environment with common utilities.

This presentation will dive into testing with Docker Containers * Building Docker containers and testing with Serverspec * Testing Docker Compose with Serverspec * Taking advantage of Docker sibling containers to run serverspec in a container * Running large test matrix with Serverspec * Demonstrate using pry/pry-rescue to debug large test The lab is available at: https://github.com/nanliu/docker-serverspec

This document discusses Node.js architecture and how software lives in hardware. It notes that Node.js uses a single-threaded, event loop model to avoid context switching and blocking I/O. This allows high throughput for operations like HTTP requests but is not optimal for long-running computations in a single thread. The document also addresses issues like callback hell and scaling event emitters, providing solutions like using promises and external queue systems. It concludes by stating Node.js is best for I/O operations, not all problems, and event loop models have existed in other frameworks before Node.js.

A quickfire rundown of concise tips designed to make your daily life with Docker better! There will be something for Docker users of all experience levels.

The document discusses test driven development (TDD) approaches for Puppet modules. It recommends writing tests before code using tools like RSpec and guard. The document provides examples of unit testing Puppet code and definitions using rspec-puppet. It also discusses acceptance testing Puppet code and modules using Beaker against real systems. Overall, the document promotes writing tests for Puppet code to ensure quality and prevent regressions across different operating systems and versions.

Vagrant allows developers to easily create and manage virtual machine environments for development. It provides a simple configuration file format and CLI to automate the setup of VMs using various providers like VirtualBox, VMware, AWS, and more. Vagrant can provision VMs using tools like Chef, Puppet, Ansible and Shell scripts. It aims to allow exact clones of production environments for testing and to simplify tasks like testing infrastructure changes.

Процесс разработки не начинается и не заканчивается на написании кода программного продукта. Мы пишем документацию, придумываем, как это всё оттестировать, и заботимся о том, чтобы доступность приложения была на высоком уровне. Мы все делаем привычные вещи привычным для нас способом. Порой выполняя много ручной и неэффективной работы. Но что, если есть другой, радикальный подход. Можно ли формализовать свою деятельность и переложить её в код? Какие практики и инструменты для этого использовать? В докладе будет представлен личный опыт автора по автоматизации различных элементов разработки ПО.

This document discusses using infrastructure as code to automate server setup and deployment using Ansible. It outlines benefits like reducing human error, allowing developers and operations teams to work seamlessly through continuous integration and testing. Specifics of the infrastructure as code stack used are covered, including Ansible for configuration management, Docker for containers, and Vagrant for local virtual machine provisioning. Challenges and lessons learned around testing, debugging, and migrating existing systems are also presented. The overall message is that infrastructure as code takes time to implement but results in major improvements to deployment speed, reliability, and ability to rapidly iterate.

This fabric workshop aims to create a deploy tool using Fabric that can deploy code to servers defined in roles, show existing tags, change to a different tagged version, and remove tags. The agenda includes demonstrating local tasks, remote tasks using an Ansible inventory file, and functions for mkdir, cd, and uploading files. Fabric provides a simple way to automate operations across multiple servers.

Zero Downtime Deployment with Ansible - learn how to provision Linux servers with a web-proxy, a database and automate zero downtime deployment of a Java application to a load balanced environment. These are the slides from a tutorial held at the Velocity Conference in Barcelona November 19th, 2014. Git repo: https://github.com/steinim/zero-downtime-ansible

This document summarizes the results of performance tests conducted on a Magento 2 store using different PHP versions and configurations. The tests measured the transaction rate, number of transactions, and response time of Magento 2 using PHP 5.6 alone, PHP 5.6 with Varnish, PHP 7 alone, and PHP 7 with Varnish. The main findings were that PHP 7 significantly outperformed PHP 5.6, and that adding Varnish provided major improvements when combined with both PHP 5.6 and PHP 7, especially in terms reducing response times.

This document provides an overview of how to write Node.js modules. It discusses writing modules in JavaScript and C/C++, loading modules, publishing modules to the NPM registry, and some advanced topics like handling arguments and creating classes. The key points covered are: - Modules can be written in JavaScript or C/C++ and exported via module.exports. - Modules are loaded using require() and can be either core or third-party modules. - Publishing a module to NPM involves initializing a package, uploading the files to the registry, and adding a main entry point. - Advanced topics include getting arguments in C/C++ modules, understanding JavaScript types, and creating classes with

This document discusses experimenting with cgroups in Docker containers to isolate processes. It describes installing Docker, launching an Ubuntu container with capabilities enabled, and installing cgroup tools. It then mounts the cpuset and cpu cgroup hierarchies and creates low and high cgroups. Different CPU shares are assigned to each cgroup and processes are run in each to demonstrate the CPU isolation between cgroups.

NPM scripts allow developers to run predefined scripts at different stages of installing, publishing, and interacting with packages. These scripts are defined in the package.json file under the "scripts" key. Common script names include preinstall, install, postinstall, prepublish, publish, and postpublish. NPM versioning follows semantic versioning principles where versions are denoted as MAJOR.MINOR.PATCH. Dependencies can specify version ranges like tilde (~), caret (^), and hyphen (-) to control updates. Private NPM repositories and shrinkwrapping help ensure reproducible builds across environments. Scoped packages allow publishing packages under a unique namespace.

My talk will cover how to work with a large C++ code base professionally. How to write code for debuggability, how to work effectively even due the long C++ compilation times, how and why to utilize the STL algorithms, how and why to keep interfaces clean. In addition, general convenience methods like making wrappers to make the code less error prone (for example ranged integers, listeners, concurrent values). Also a little bit about common architecture patterns to avoid (virtual classes), and patterns to encourage (pure functions), and how std::function/lambda functions can be used to make virtual classes copyable.

Workshop about responsive web design (RWD), given on 13 Februari 2013. This is a presentation about how to create a responsive website. Different tools and libraries which are used for RWD are covered Examples used in the workshop can be found here: https://github.com/Goldmund-Wyldebeast-Wunderliebe/rwd-workshop

Buildout is a build tool for Python projects. It's a self-contained environment which manages depencies for a project, install/configure software components and create repeatable DTAP enviroments.
