Docker Security Deep Dive by Ying Li and David Lawrence
Securing software supply chains and deployed systems is important. The document discusses using Docker Content Trust (DCT) to ensure authenticity, integrity, and freshness of container images. It also recommends validating dependencies, signing applications, scanning for vulnerabilities, and using features in Docker 1.12 like mutual TLS and certificate rotation to securely manage Docker clusters.
Sharding Containers: Make Go Apps Computer-Friendly Again by Andrey Sibiryov
The document discusses how modern hardware has become more complex with multi-core, multi-socket CPUs and deep cache hierarchies. This complexity introduces latency and performance issues for software. The author describes their service that processes millions of requests per second spending a large amount of time on garbage collection, context switching, and CPU stalls. They developed a tool called Tesson that analyzes hardware topology and shards containerized applications across CPU cores, pinning linked components closer together to improve locality and performance. Tesson integrates with a local load balancer to distribute workloads efficiently utilizing the system resources.
What's New in Docker 1.12 (June 20, 2016) by Mike Goelzer & Andrea Luzzardi
Docker 1.12 introduces several new features for managing containerized applications at scale including Docker Swarm mode for native clustering and orchestration. Key features include services that allow defining and updating distributed applications, a built-in routing mesh for load balancing between nodes, and security improvements like cryptographic node identities and TLS encryption by default. The document also discusses plugins, health checks, and distributed application bundles for declaring stacks of services.
runC: The little engine that could (run Docker containers) by Docker Captain ...
With the announcement of the OCI by Solomon Hykes at last summer's DockerCon, a Docker-contributed reference implementation of the OCI spec, called runC, was born. While some of you may have tried runC or have a history of poking at the OS layer integration library to Linux namespaces, cgroups and the like (known as libcontainer), many of you may not know what runC offers. In this talk Phil Estes, Docker engine maintainer who has also contributed to libcontainer and runC, will show what's possible using runC as a lightweight and fast runtime environment to experiment with lower-level features of the container runtime. Phil will introduce a conversion tool called "riddler", which can inspect and convert container configurations from Docker into the proper OCI configuration bundle for easy conversion between the two environments. He'll also demonstrate how to make custom configurations for trying out security features like user namespaces and seccomp profiles.
Containerd: Building a Container Supervisor by Michael Crosby
Containerd is a container supervisor that allows users to manage the lifecycle of a container as well as interact with the container while it is executing. Containerd was built to fulfill many of the requirements that we expect from a modern supervisor all while staying small and fast. In this talk, we will discuss some of the design decisions that shaped containerd’s architecture that allows it to reattach to running containers if it was killed and how it is designed to start 100s containers in seconds.
Getting Deep on Orchestration: APIs, Actors, and Abstractions in a Distribute...
Orchestration platforms let us work with higher level ideas like services and jobs; but there is more to a platform than scheduling and service discovery. A platform is a collection of actors and APIs that work together and provide those higher level abstractions on a distributed system. In this session we'll go deep on the architecture of open source orchestration platforms, consider scaling pains, reveal extension points, and reflect on an orchestration platform at Amazon. We'll finish with a demo of a homemade abstraction deployed on a live, multi-cloud Swarm cluster.
Thinking Inside the Container: A Continuous Delivery Story by Maxfield Stewart
Riot builds a lot of software. At the start of 2015 we were looking at 3000 build jobs over a hundred different applications and dozens of teams. We were handling nearly 750 jobs per hour and our build infrastructure needed to grow rapidly to meet demand. We needed to give teams total control of the “stack” used to build their applications and we needed a solution that enabled agile delivery to our players. On top of that, we needed a scalable system that would allow a team of four engineers to support over 250.
After as few explorations, we built an integrated Docker solution using Jenkins that accepts docker images submitted as build environments by engineers around the company . Our “containerized” farm now creates over 10,000 containers a week and handles nearly 1000 jobs at a rate of about 100 jobs an hour.
In this occasionally technical talk, we’ll explore the decisions that led Riot to consider Docker, the evolutionary stages of our build infrastructure, and how the open source and in-house software we combined to achieve our goals at scale. You’ll come away with some best practices, plenty of lessons learned, and insight into some of the more unique aspects of our system (like automated testing of submitted build environments, or testing node.js apps in containers with Chromium and xvfb).

The Golden Ticket: Docker and High Security Microservices by Aaron Grattafiori
True microservices are more than simply bolting a REST interface on your legacy application, packing it in a Docker container and hoping for the best. Security is a key component when designing and building out any new architecture, and it must be considered from top to bottom. Umpa Lumpas might not be considered "real" microservices, but Willy Wonka still has them locked down tight!
In this talk, Aaron will briefly touch on the idea and security benefits of microservices before diving into practical and real world examples of creating a secure microservices architecture. We'll start with designing and building high security Docker containers, using and examining the latest security features in Docker (such as User Namespaces and seccomp-bpf) as well as examine some typically forgotten security principals. Aaron will end on exploring related challenges and solutions in the areas of network security, secrets management and application hardening. Finally, while this talk is geared towards Microservices, it should prove informational for all Docker users, building a PaaS or otherwise.
Microservices + Events + Docker = A Perfect Trio by Docker Captain Chris Rich...
The document discusses how microservices, events, and Docker form a perfect trio for developing and deploying applications. It covers how microservices can help accelerate development but also introduce complexity that events and Docker can help address. Events are proposed to maintain data consistency between microservices rather than distributed transactions. Docker is presented as a way to containerize microservices for improved isolation, manageability and efficient deployment and scaling. The overall presentation argues this combination of techniques can help build large, complex applications.

Php Code Profiling Using X Debug
Presented by Gennady Feldman at Web Peformance for PHP developers (NY Web Performance Meetup & NY PHP).
Xdebug is a very powerful PHP extension that should be in the toolbox of any PHP developer. In this quick presentation we will do a quick introduction into some of the things Xdebug is capable of and what it can do for you. We'll cover a number of Xdebug features like remote debugging and code profiling. Forget those print and echo statements as your debugging aids. Gennady will share some tips and tricks (time permitting) of how to be a more efficient and productive PHP developer.
http://www.nyphp.org/content/presentations/
Getting Started With Xdebug
The document provides an overview of Xdebug, an open source PHP extension that enables debugging and profiling of PHP applications. It discusses Xdebug features like stepping through code line-by-line, viewing application data at breakpoints, and function call stack tracing. The document also covers installing and configuring Xdebug, enabling and disabling debugging sessions, and using tools like KCacheGrind and Webgrind for profiling. Useful Xdebug functions and additional resources are listed.
Forensic Theming - DrupalCon London
The theme of your website has the capacity for beautiful, semantic markup...and also the hacky HTML soup. You can build a new theme by downloading a free theme and tearing out its guts--or you can learn how to become a theme surgeon.
In this session you will learn two key techniques needed to build a successful theme: crime scene investigation (identifying Drupal page elements in your design files) and power tools for copy-cat theming (things you need to recreate your design using Drupal). From start to finish we will transform a design file into a Drupal theme. With special attention given to your all-important questions: how do I save time with grid-based design? Should I use Panels? How do I make this bit of stuff appear next to that bit? Yah, but how do I start?
[This presentation was given at DrupalCon Chicago but the recording failed. Slides are available from http://www.slideshare.net/emmajane/forensic-theming-for-drupal]

Achievers' own Kaelen Proctor talks about different ways to profile and tune a web application for the best performance possible.
Mongo NYC PHP Development
The document is a presentation about using MongoDB with PHP development. It introduces the speaker and provides reasons why PHP developers should use MongoDB, including its document-oriented storage, indexing support, replication, querying and map-reduce capabilities. It discusses how MongoDB fits with PHP's object-oriented nature. It provides an e-commerce use case example and overview of using MongoDB with PHP frameworks and the MVC pattern. It encourages attendees to explore more online resources for using MongoDB and PHP.
PHP Aberdeen Quick optimisation of PHP with Webgrind
Webgrind is a PHP profiling tool that provides a quick way to optimize PHP applications. It works by interfacing with the Xdebug profiler to generate call graphs and profiling data. Webgrind is easy to install, works on all platforms, and allows developers to characterize code performance, find slow parts of applications and libraries, and understand how systems work in order to make optimizations. The document provides steps on installing Xdebug, enabling it, installing and configuring Webgrind, and using it to analyze profiling data and call graphs to optimize an API that was experiencing slowdowns from increased data sizes.
BinaryPig - Scalable Malware Analytics in Hadoop
The document describes BinaryPig, a framework for processing small binary files like malware samples using Apache Hadoop and Apache Pig. It allows for scalable storage and analysis of large datasets. BinaryPig addresses issues with previous approaches like lack of data locality, failure resilience, and dynamic schema support. It introduces loaders for running analysis scripts and daemons on binary data to extract features. Clustering results on a dataset of 20 million malware samples are also presented to demonstrate BinaryPig's capabilities for malware triage and research.
Zend Code in ZF 2.0
This is a low-level, and philosophical discussion on the act of compiling data out of your PHP applications using Zend\Code: Scanning, Generating, Annotating code in PHP.
Decoupling Content Management
This document discusses decoupling content management from monolithic content management systems. It introduces Create.js, a web editing interface that can work with different backends. Create.js uses JSON-LD and RDFa to allow content to be understood semantically. The document also discusses PHPCR, a PHP implementation of the Java Content Repository standard, which provides a common API for different content repositories like Jackrabbit and Midgard2. PHPCR allows storing content in a tree with nodes, properties, and versions. It enables decoupling web applications from the underlying data storage through its standardized API.
Adobe AEM CQ5 - Developer Introduction
This document provides an introduction to Adobe Experience Manager (AEM), formerly known as CQ5. It discusses key aspects such as installation, prerequisites, content authoring, templates, components, workflows and more.

Webinar: Managing Real Time Risk Analytics with MongoDB
Learn how customers are using MongoDB to aggregate risk data from multiple front office sources to calculate exposure.
Xdebug for Beginners
var_dump($foo);
print_r($bar);
die($baz);
Are these your current debugging tools? Wouldn't it be nice to see $foo, $bar, and $baz while the code is still being executed? Watch it change, live? And not have it just dumped all over the output of your otherwise beautiful app? We'll install XDebug, set up your IDE to use it (with examples shown for PhpStorm, Netbeans, and ZendStudio), then we'll actually walk through some badly written code that needs to be debugged.

"NATO Hackathon Winner: AI-Powered Drug Search", Taras Kloba
This is a session that details how PostgreSQL's features and Azure AI Services can be effectively used to significantly enhance the search functionality in any application.
In this session, we'll share insights on how we used PostgreSQL to facilitate precise searches across multiple fields in our mobile application. The techniques include using LIKE and ILIKE operators and integrating a trigram-based search to handle potential misspellings, thereby increasing the search accuracy.
We'll also discuss how the azure_ai extension on PostgreSQL databases in Azure and Azure AI Services were utilized to create vectors from user input, a feature beneficial when users wish to find specific items based on text prompts. While our application's case study involves a drug search, the techniques and principles shared in this session can be adapted to improve search functionality in a wide range of applications. Join us to learn how PostgreSQL and Azure AI can be harnessed to enhance your application's search capability.
Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Lee Barnes - Path to Becoming an Effective Test Automation Engineer.pdf
So… you want to become a Test Automation Engineer (or hire and develop one)? While there’s quite a bit of information available about important technical and tool skills to master, there’s not enough discussion around the path to becoming an effective Test Automation Engineer that knows how to add VALUE. In my experience this had led to a proliferation of engineers who are proficient with tools and building frameworks but have skill and knowledge gaps, especially in software testing, that reduce the value they deliver with test automation.
In this talk, Lee will share his lessons learned from over 30 years of working with, and mentoring, hundreds of Test Automation Engineers. Whether you’re looking to get started in test automation or just want to improve your trade, this talk will give you a solid foundation and roadmap for ensuring your test automation efforts continuously add value. This talk is equally valuable for both aspiring Test Automation Engineers and those managing them! All attendees will take away a set of key foundational knowledge and a high-level learning path for leveling up test automation skills and ensuring they add value to their organizations.
