Docker is not just about deploying containers to hundreds of servers. Developers need tools that help with day-to-day tasks and to do their job more effectively. Docker is a great addition to most workflows, from starting projects to writing utilities to make development less repetitive. Docker can help take care of many problems developers face during development such as “it works on my machine” as well as keeping tooling consistent between all of the people working on a project. See how easy it is to take an existing development setup and application and move it over to Docker, no matter your operating system.

Plack perl superglue for web frameworks and serversTatsuhiko Miyagawa

Plack provides a common interface called PSGI (Perl Server Gateway Interface) that allows Perl web applications to run on different web servers. It includes tools like Plackup for running PSGI applications from the command line and middleware for adding functionality. Plack has adapters that allow many existing Perl web frameworks to run under PSGI. It also provides high performance PSGI servers and utilities for building and testing PSGI applications.

Modern Web Development with PerlDave Cross

This document summarizes a presentation about building web applications in Perl using PSGI and Plack. It discusses: - The history of CGI and its problems with performance - How mod_perl and other environments addressed these issues but reduced portability - How PSGI separates web application processing from deployment, allowing applications to run on different servers and frameworks - A PSGI application is defined as a code reference that returns a response as an array reference - Plack provides helpers like Plack::Request and Plack::Response to simplify building PSGI applications - Template Toolkit can be used to separate HTML templates from application code - User input can be accessed from the environment hash or Plack::Request object

Modern Perl for the Unfrozen Paleolithic Perl ProgrammerJohn Anderson

Hello, unfrozen Paleolithic Perl programmers! Welcome to 2015! First, let’s start with the good news: yes, we’re still programming in Perl5 in 2015 (and yes, we think that’s good news). Indeed, most of the code you wrote in the past, before that unfortunate "Big Giant Hole in Ice" incident, will likely still work just fine on the current release of Perl5 -- even if you originally wrote it against Perl 4 or even Perl 3. Here’s the bad news: there’s been an incredible amount of innovation in not only Perl5-the-language, but also in Perl5-the-community and what the community considers to be accepted best practices and the right way to do things. It can be very frightening and confusing! But wait, there’s more good news: if you come to this talk, you’ll get a guided tour of my (reasonably opinionated) views on what the consensus best practices are around issues such as which version of Perl5 to use, system Perl versus non-system Perl, Perl5 installation management packages, new language features and libraries to use, old language features and libraries to avoid, modern tooling, and even more!

Plack at YAPC::NA 2010Tatsuhiko Miyagawa

Plack is a superglue for Perl web frameworks that provides a common interface called PSGI (Perl Web Server Gateway Interface) inspired by WSGI and Rack. PSGI allows any web application or framework to run on any web server by providing a standard way for applications to communicate with servers. Plack also includes tools like Plackup for running PSGI applications from the command line and middleware for common functionality that can be shared across frameworks. Many existing Perl web frameworks have been adapted to run under PSGI through Plack.

Intro to PSGI and PlackTatsuhiko Miyagawa

PSGI is a Perl port of Python's WSGI and Ruby's Rack that defines a common interface between web servers and frameworks. Plack provides reference implementations of PSGI servers as well as middleware and utilities. This allows frameworks to run on many servers like standalone, FastCGI, and Apache using a common PSGI application interface. Plack is fast, supports many frameworks through adapters, and provides tools like Plackup and middleware to help build and test PSGI applications.

Matt Gauger - Lamp vs. the world - MKE PHP Users Group - December 14, 2010 Matt Gauger

This document summarizes a talk comparing PHP and Rails web development frameworks. It discusses the evolution of web servers from Apache to more scalable options like Nginx. Nginx acts as a reverse proxy, passing requests to application servers like FastCGI that execute code and return responses. This represents a shift from simply serving static files to building full-featured web applications using the MVC pattern. Node.js is presented as the next step, allowing JavaScript to be used for server-side development in an event-driven, non-blocking way.

Serverless in production, an experience report (LNUG)Yan Cui

AWS Lambda has changed the way we deploy and run software, but this new serverless paradigm has created new challenges to old problems - how do you test a cloud-hosted function locally? How do you monitor them? What about logging and config management? And how do we start migrating from existing architectures? In this talk Yan and Scott will discuss solutions to these challenges by drawing from real-world experience running Lambda in production and migrating from an existing monolithic architecture.

Getting started with Apache Camel - jDays 2013Claus Ibsen

In this session will teach you how to get a good start with Apache Camel. We will introduce you to Apache Camel and how Camel its related to Enterprise Integration Patterns. And how you go about using these patterns in Camel routes, written in Java code or XML files. We will then discuss how you can get started developing with Camel, and how to setup new projects from scratch using Maven and Eclipse tooling. This session includes live demos that show how to build Camel applications in Java, Spring, OSGi Blueprint and alternative languages such as Scala and Groovy. You will also hear what other features Camel provides out of the box, which can make integration much easier for you. We also take a moment to look at hawtio, then hot new web console tooling that allows you to get insight into your running Apache Camel applications, which has among others visual route diagrams with tracing/debugging and profiling capabilities. Before opening up for QA, we will share useful links where you can dive into learning more about Camel.

Everything-as-code. A polyglot adventure. #DevoxxPLMario-Leander Reimer

As modern, agile architects and developers we need to master several different languages and technologies all at once to build state-of-the-art solutions and yet be 100% productive. We define our development environments using Gradle. We implement our software in Java, Kotlin or another JVM based language. We use Groovy or Scala to test our code at different layers. We construct the build pipelines for our software using a Groovy DSL or JSON. We use YAML and Python to describe the infrastructure and the deployment for our applications. We document our architectures using AsciiDoc and JRuby. Welcome to Babel! Making the right choices in the multitude of available languages and technologies is not easy. Randomly combining every hip technology out there will surely lead into chaos. What we need is a customized, streamlined tool chain and technology stack that fits the project, your team and the customer’s ecosystem all at once. This code intense, polyglot session is an opinionated journey into the modern era of software industrialization.

Integration using Apache Camel and GroovyClaus Ibsen

Apache Camel is versatile integration library that supports a huge number of components, enterprise integration patterns, and programming languages. In this this talk I first introduce you to Apache Camel and its concepts. Then we move on to see how you can use the Groovy programming language with Camel as a first class Groovy DSL to build integration flows. You will also learn how to build a new Camel and Groovy app from scratch from a live demo. And we also touch how you can use Camel from grails using the grails-camel plugin. I will also show the web console tools that give you insight into your running Apache Camel applications, including visual route diagrams with tracing, debugging, and profiling capabilities. This session will be taught with a 50/50 mix of slides and live demos, and it will conclude with Q&A time.

Serverless in Production, an experience report (cloudXchange)Yan Cui

This document provides advice on preparing serverless applications for production based on the author's experience deploying 170 Lambda functions to production. It covers important areas to consider like testing at the unit, integration, and acceptance levels; setting up CI/CD pipelines; monitoring, logging, and alerting; distributed tracing; security; and configuration management. The author emphasizes the importance of testing end-to-end without mocking external services, setting up production-ready monitoring and metrics dashboards, and choosing deployment frameworks that are tried and tested.

Microservices with apache_camel_barcelonaClaus Ibsen

Apache Camel is a very popular integration library that works very well with microservice architecture. This talk introduces you to Apache Camel and how you can easily get started with Camel on your computer. Then we cover how to create new Camel projects from scratch as micro services which you can boot using Camel or Spring Boot, or other micro containers such as Jetty or fat JARs. We then take a look at what options you have for monitoring and managing your Camel microservices using tooling such as Jolokia, and hawtio web console. The second part of this talk is about running Camel in the cloud.We start by showing you how you can use the Maven Docker Plugin to create a docker image of your Camel application and run it using docker on a single host. Then kubernetes enters the stage and we take a look at how you can deploy your docker images on a kubernetes cloud platform, and how the fabric8 tooling can make this much easier for the Java developers. At the end of this talk you will have learned about and seen in practice how to take a Java Camel project from scratch, turn that into a docker image, and how you can deploy those docker images in a scalable cloud platform based on Google's kubernetes.

Api Designsumithra jonnalagadda

The document discusses API design in PHP, focusing on Ning's PHP API. Some key points: - Ning's PHP API provides a REST interface to its social networking platform and has been in use since 2005. - The API is used for content storage, user profile management, tagging, search, and other functions. - Good API design principles include making things predictable, modular, stable, and prioritizing human performance over computer performance. - API design should be use case driven and additions should be easy while removals are hard. Names, versioning, and documentation are important.

ClojureScript - Making Front-End development Fun again - John Stevenson - Cod...Codemotion

Front-end development has an amazing assortment of libraries and tools, yet it can seem very complex and doest seem much fun. So we'll live code a ClojureScript application (with a bit of help from Git) and show how development doesn't have to be complex or slow. Through live evaluation, we can build a reactive, functional application. Why not take a look at a well designed language that uses modern functional & reactive concepts for building Front-End apps. You are going to have to trans-pile anyway, so why not use a language, libraries and tooling that is bursting with fun to use.

Leveraging a distributed architecture to your advantageMichelangelo van Dam

The days of a "simple" LAMP stack are behind us. We now rely on different types of technologies, applications and services to run our web based applications. With "the cloud" we have learned how to distribute our operations, but are we resilient when these cloud services are not available? We have all heard about the major outages of Amazon and Azure in the past and many online services were impacted by those outages. So how can you protect yourself against being "offline" for hours or days and what are the tools you can use to protect yourself against it? Learn how we protect our customers with distributed systems (cloud and on-prem) to mitigate outages and stay online even when the lights go out.

Unit Testing for Great JusticeDomenic Denicola

The discovery of unit testing and test-driven development was one of the most important parts of my growth as a developer. The ability to write simple, small pieces of code that could verify the behavior of my application was in itself quite useful. And the ability to refactor without fear, just by running the test suite, changed how I program. But the real benefits come in how unit tests shape your application code: more testable code is often more well thought-out, more decoupled, and more extensible. In this talk, I'll give a whirlwind introduction to unit testing as a concept and as a practice. I want you fully convinced it's the best thing to happen to software development, if you aren't already. Once we're on the same page there, I'll take a deep dive into what makes a good unit test. This involves testing tools such as spies, stubs, and mocks, concepts like code coverage, and practices like dependency injection that shape your application code. The most important lesson will be on how to focus on singular, isolated units of code in your testing, as this guides you toward building modular, flexible, and comprehensible applications.

Developers spend an enormous amount of time making sure that their applications are as fast as possible, but tuning your web server can only go so far. Async Programming is being used by many languages as a quick and easy way to serve web applications, and PHP is no exception. Libraries like ReactPHP and Amp, alongside extensions like Swoole, give developers broad choices for how to build their applications using async principles. See how these tools and async programming can help your application stay quick and agile.

Docker for DevelopersChris Tankersley

Thanks to tools like Vagrant, Puppet/Chef, and Platform as a Service services like Heroku, developers are extremely used to being able to spin up a development environment that is the same every time. What if we could go a step further and make sure our development environment is not only using the same software, but 100% configured and set up like production. Docker will let us do that, and so much more. Docker is fast becoming an important part of many developers toolkits. Not only are more developers using it day-to-day, but it is also becoming an important tool for deployments. We'll look at what Docker is, why you should consider using it, and all of the features developers can take advantage of.

They are Watching YouChris Tankersley

Humanity has seen an explosion of technology over the span of almost no time. We have gone from computers being mechanical devices for crunching trajectories to computers making decisions on whether or not we are dressing fashionably. We have also seen an explosion of services that resolve around massive amounts of data about ourselves. At the same time we see developers working on Tor, ad blockers, privacy tools, and ways to keep your data yours. Programmers just like us are building these systems. What are our moral obligations to the technology that we are building? Strap on your tinfoil hat and [REDACTED]

BASHing at the CLI - Midwest PHP 2018Chris Tankersley

The Command Line should be a developer's best friend, but many times it sits there, sad and lonely as we use to call other programs. Behind that unassuming little blinking cursor is an entire world of productivity, just waiting to be strung together. There is even an entire scripting language hidden underneath that is just waiting for you to use it! Let's investigate BASH, the shell that's syntax is universal across almost all systems (and find out why your Linux scripts do not always work on OSX).

You Were Lied To About OptimizationChris Tankersley

Many know of the famous quote, "Premature optimization is the root of all evil," but most people do not know the full quote or understand the context in which optimization is considered evil. As with anything in programming optimization is evil, maybe. Stop using excuses for slow code, and start to think about the places and tools that you can use to optimize. Thankfully there are are many different tools like xhprof, Valgrind, and others to help us out and properly optimize our code for those times when we need to dig deep into our code.

OOP Is More Then Cars and Dogs - Midwest PHP 2017Chris Tankersley

When developers are introduced to Object Oriented Programming, one of the first things that happens is that they are taught that nouns turn into objects, verbs into methods, and Dog is a subclass of Animal. OOP is more than just turning things into classes and objects and showing that both Boats and Cars have motors, and that Dogs and Cats both speak(). Let's look at OOP in real world settings and go beyond cars and dogs, and see how to use Object Oriented Programming properly in PHP. Traits, Composition, Inheritance, none of it is off limits!

From Docker to Production - SunshinePHP 2017Chris Tankersley

Congrats! You and your coworkers love Docker. Docker has become an increasingly helpful tool when it comes to devops. We can now build smaller, more robust local development setups with the promise of mirroring production. One thing that still plagues many situations is how to get those containers into production and update them over time. We will explore different tools for setting up, configuring, and maintaining containers as they go live.

Coming to Terms with OOP In Drupal - php[world] 2016Chris Tankersley

The document discusses object-oriented programming (OOP) concepts in PHP and Drupal, including classes, objects, inheritance, composition, interfaces, and design principles like the single responsibility principle. It provides examples of how procedural code can be rewritten using OOP patterns to make the code more modular, reusable, and testable. Key benefits of OOP like code reuse and extensibility are highlighted.

How We Got Here: A Brief History of Open SourceChris Tankersley

The document provides a brief history of open source software. It discusses early computers like the Commodore 64 from the 1980s and contrasts it with modern smartwatches. It also outlines the hacker ethics of free access to information and decentralization. Richard Stallman is quoted advocating for sharing software freely rather than restricting it. The presentation concludes with credits to images used.

Docker for PHP Developers - ZendCon 2016Chris Tankersley

This document provides an overview of Docker for PHP developers. It begins with definitions of containers and how they differ from virtual machines. It then demonstrates how to run simple PHP containers with Docker, including linking containers to share data and network resources. The document discusses volumes, networks, and building custom Docker images. It promotes Docker Compose for defining and running multi-container apps. Overall, the summary introduces Docker concepts and shows how it can benefit PHP development workflows.

Oh Crap, My Code is Slow - Madison PHP 2016Chris Tankersley

There are many excuses that developers use for inefficient code - CPU and RAM is cheap these days, or PHP is by default a slow language. These are just a few of those. What happens when your code is actually to slow to scale? Most of us will not deal with things on the scale of Facebook or Google, but there will come a time where we will need to figure out why code is slow. Thankfully there are are many different tools to help us out and properly optimize our code for those times when we need to dig deep into our code.
