This document discusses dependency injection and the Pimple dependency injection container. It explains what dependency injection is, how it improves code by removing tight coupling, and how a dependency injection container like Pimple works. Pimple allows defining services that are injected where needed, avoiding repetitive instantiation of objects. It implements ArrayAccess to allow accessing services like an array. This reduces complexity and improves testability over directly instantiating dependencies, though it can make code less intuitive for IDEs.
Perl changed the speaker's life in several ways:
1) The speaker met his wife on a Perl-based chat site in 1998.
2) The speaker's career path led him to technical management roles where he uses Perl and Perl-based tools extensively to develop internal systems.
3) Interacting with the Perl community through conferences and online helped the speaker advance his technical skills and career.

The document introduces the Guzzle HTTP client library for PHP, covering its main features and providing examples of basic usage. It discusses Guzzle's asynchronous capabilities using Guzzle Promises and how to test requests using a MockHandler. The handler is highlighted as central to Guzzle's functionality, with examples given of different handler types that can be passed to the client. Contributing to Guzzle's large codebase is encouraged.
This document discusses installing PHP7 on CentOS7 using Ansible. It provides commands to install the EPEL and Remi repositories, install PHP7 and related packages, and enable PHP7. It then shows how this process can be automated using Ansible roles and playbooks, including links to the example role and playbook on GitHub.
This document summarizes a presentation about single-page applications (SPAs). It discusses what SPAs are, some user experience challenges with SPAs like navigation and accessibility, and solutions to those challenges including server-side rendering and preloading resources. Links are provided to additional resources on topics like accessibility in SPAs and using service workers and prefetching to improve performance. The document concludes by thanking attendees of the presentation.
