You'll learn how to take a quick peek at recent log messages from a single log file, how to do the same thing with multiple logs, as well as watching log files in real time! We'll finish up with a practical application, to see why this is useful.

Welcome to a special series on Project Management from Drupalize.Me. This series differs from our usual format of screencasts and presentations. We interviewed Lullabot's technical project managers, the Chief Operating Officer, and the Account Director, and organized the footage into a series of lessons on topics that project managers (PMs) deal with on a regular basis, including contracts, communication, estimation, tools and methodologies.
Here's what we'll be covering in this Introduction to Project Management series:

- Launch and Celebration: Learn some tips for ensuring a successful launch and the importance of celebrating the accomplishments of the team.
Whether you are a developer-turned-project-manager or a seasoned veteran, we think you will find insight into the art and science of project management in this series.
In this lesson, you’ll learn about methodologies and techniques that are often used in project management. These methodologies provide a set of processes for a development team to utilize, and a framework that a project manager can use to structure a project’s tasks and progress. You’ll hear from project managers at Lullabot who explain terms such as Waterfall, Agile, Wagile or Consultancy Scrum, Kanban, Scrum, and Sprints and how a tailored combination of these techniques often leads to the best results.

In this lesson, we’ll hear from Lullabot project managers about what they think makes a good ticket tracking system, some helpful ways to organize tickets, and other features including tracking conversations, email notifications, and reporting features that many ticket software platforms can provide. We’ll also hear about a tool called a Gantt chart which can help a project manager answer questions such as “when the project will be finished”, “what the critical path is”, and “what are the dependencies in this project?”

In this lesson, you’ll hear from Lullabot’s Chief of Operations, Account Director, and several technical project managers about what they think makes a good project manager. These traits of a good PM include: being a great communicator, having the ability to distill a project into tasks, taking initiative to clear blockers for developers, probing stakeholders for requirements, assumptions, and other vital information, demonstrating leadership, and finally being able to have difficult conversations with clients—discussing uncomfortable truths with tact and diplomacy. Are you on the path to becoming a project manager? Or maybe you’re looking to improve your skills? With these insights, learn about the variety of technical and people skills that make for a great project manager.

PHP Service Classes
FreeIn this course, we're going to continue on from the Introduction to Object-Oriented PHP series. We're working on the same spaceship project: it has ships, you choose them, then they engage in epic battle!
In an editor, far far away, you'll see a simple application that runs this: index.php is the homepage and battle.php does the magic and shows the results. In the first course, we created a single class called Ship
, which describes all its properties—it's like a container for one ship's details. In this tutorial we're going to replace our flat functions and create a BattleManager
service class to provide the methods we'll need to do that.

This presentation outlines some of the major changes to the way that themes are built in Drupal 8 and is intended to help you generate a list of the things you're going to need to know in order to start making awesome Drupal 8 themes. A lot has changed, and there are a lot of new things to learn. However, one of the primary focuses has been on making the theme layer easier to understand, and easier to get started with.
Almost every aspect of the theming layer has been touched in one way or another during the Drupal 8 development cycle. We think some of the important ones to learn about are:
- How Drupal 8 makes the theme layer easier to understand
- Changes to help make Drupal responsive and mobile friendly
- The adoption of current best practices for HTML5, CSS, and JavaScript
- The addition of a new template engine based on Twig
After watching this presentation you should have a better understanding of the things you'll need to learn in order to create themes in Drupal 8 and where you might need to brush up.

This presentation introduces the Drupal 8 configuration management system (CMI). Learn why configuration management is one of the most eagerly anticipated features of Drupal 8, and how it has the potential to completely change the workflow we use for building sites with Drupal. By addressing a number of long-standing issues in Drupal, CMI helps to separate content from configuration, provides a simple user interface for transporting configuration changes between multiple instances of the same site, and gives developers a consistent way to store and retrieve configuration in their code that is guaranteed to work with the rest of management tools provided.
Here's what we'll cover in this presentation:
- What is configuration management, and what problems does it solve
- The CMI user interface, and changes for site-builders
- The CMI API, and changes for modules developers
- What you can start learning now to ensure you're ready to use CMI
After watching this presentation you should have a better understanding of the importance of the new configuration management system and be excited about the improved workflows and ability to follow current best practices that it introduces to Drupal.
