Slides of my presentation delivered to Szeged Drupal DevDays 2014: http://szeged2014.drupaldays.org/program/sessions/image-system-new-world-order Moving the image system to Drupal 8 was a huge undertaking. Most of image components were converted to classes and plugins. Now the whole system is more flexible, extensible and modern. Attend this session to find out how it works in Drupal 8 and how it's structured in the new OO environment. After having a quick overview of the new API you'll learn how to: - provide image styles by code, - add new image style effects, - add or alter image operations, ...or even add new image toolkits instead of builtin GD2.

We've all been there: lookin' a thousands line spaghetti code of CSS, scrolling up and down, trying to find all the declarations, which override each other here and there, and almost cry when we find out that changing one thing affects a lot more page elements than we expected. (In the meantime we mumble some angry words about the previous developer of the file and sometimes we realize that we are talking about ourselves…) Slides form my workshop @ drupalaton: http://2014.drupalaton.hu/schedule#speaker-22

Save 10% off ANY FITC event with discount code 'slideshare' See our upcoming events at www.fitc.ca OVERVIEW As most Android developers know, dealing with the extreme degree of fragmentation in the Android ecosystem is often challenging. Among the more difficult challenges is managing memory usage, as devices that are in the market today can have as little as 13MB of memory. Now imagine the pains that developers go through when faced with the headache of having massive bitmaps eat up memory in a millisecond. In this presentation, James Halpern will talk about the complexities of image and memory management in Android and walk you through the creation of a successful, powerful and open source image management utility. Come to this presentation to learn about techniques that will help you optimize the performance of your apps. Learn about Android’s memory limitations and the role the garbage collector plays in your app’s performance and complexity. Learn how to communicate android graphics issues to developers, and how good design can create fewer bugs. James will conclude this presentation by briefly walking you through his open sourced image management solution that gracefully handles most of these issues in a simple to use package.

WordCamp NEO 2016 presentation "Custom Responsive Theme Workshop" by David Brattoli While we could use many different frameworks, premium and free themes to build our sites, I have found you need a truly custom framework to build a base to build new themes quickly to meet your project needs. This method to create a framework and then to create a child theme for the look of the site, will allow you build future sites quickly and efficiently. The session will cover why we choose this method and framework, the challenges we faced, how we tackled the challenge, and what we ended up building to solve the problem. I'll also reveal the pitfalls we discovered and how we overcame those as well. Coding samples can be found here: http://bit.ly/wceno-crtw-samples

Want to learn more about Acquia’s products, services, and happenings in the Drupal Community? Visit our site: http://bit.ly/yLaHO5. Drupal 8 has introduced a number of new (to Drupalists) technologies, but embedded in this mix are a handful of Drupal-centric innovations. Amongst the first of these to be introduced to Drupal 8 was the Plug-in system. The Plug-in system is a far reaching PHP Component that has largely replaced the old hook_info/alter pattern within Drupal and can be used outside of Drupal as well. In this webinar, Kris Vanderwater (You may know him as EclipseGc) will review: • Examples of what appropriate plug-in system usages look like • What plug-in tools exist and how to leverage them • Where to get information on building your own plug-in types • How to use the existing helper classes in Drupal for the greatest impact We will compare and contrast how Drupal 7 versus Drupal 8 works for plugin converted subsystems to frame the discussion around when and why to build a conversion. In addition to this we will dig into the tools and classes Drupal provides out of the box, and dissect a simple example plug-in type that you can use to build your own plug-ins types and better understand the plug-in system. Experience level: Advanced

The microservices honeymoon is over. When starting a new project or revamping a legacy monolith, teams started looking for alternatives to microservices. The Modular Monolith, or 'Modulith', is an architecture that reaps the benefits of (vertical) functional decoupling without the high costs associated with separate deployments. This talk will delve into the advantages and challenges of this progressive architecture, beginning with exploring the concept of a 'module', its internal structure, public API, and inter-module communication patterns. Supported by spring-modulith, the talk provides practical guidance on addressing the main challenges of a Modultith Architecture: finding and guarding module boundaries, data decoupling, and integration module-testing. You should not miss this talk if you are a software architect or tech lead seeking practical, scalable solutions. About the author With two decades of experience, Victor is a Java Champion working as a trainer for top companies in Europe. Five thousands developers in 120 companies attended his workshops, so he gets to debate every week the challenges that various projects struggle with. In return, Victor summarizes key points from these workshops in conference talks and online meetups for the European Software Crafters, the world’s largest developer community around architecture, refactoring, and testing. Discover how Victor can help you on victorrentea.ro : company training catalog, consultancy and YouTube playlists.
