Introduction to node.js
Node.js is a JavaScript runtime built on Chrome's V8 engine that is used to develop fast and scalable network applications. It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, especially for data-intensive real-time applications that run across distributed devices. Node.js relies heavily on asynchronous event handling, callbacks, and data streams.
ExpressJs Session01
The document discusses Express.js, a web framework for Node.js. It provides an overview of Express.js and how it can be used to start an application server listening on a port, handle HTTP requests asynchronously with methods like GET and POST. It also includes code samples of setting up a basic Express server with a "Hello World" route, installing Express, and using routes to define how the app responds to different URIs and HTTP methods.
Groovy with Mule
This document demonstrates how to use a Groovy scripting component to pause a Mule flow for a period of time before processing the payload. The flow uses a file inbound endpoint to pick up a file, passes it to a Groovy script that sleeps for 3000ms, and then sends the file to a file outbound endpoint. The Groovy script allows pausing the flow by calling the sleep method, holding the payload for a specified interval before continuing processing.
RingoJS
RingoJS is a JavaScript platform that runs on the JVM. It was started by Hannes Wallnöfer and is the successor to Helma and HelmaNG. RingoJS conforms to CommonJS standards and supports features like hot reloading, profiling, debugging, and sandboxing. It can run as a standalone process or within a web application container since it runs on the JVM. Examples are provided of using RingoJS for multithreaded JavaScript and web applications using libraries like Stick. Community support is available on IRC and Twitter. RingoJS can be used for standalone applications, extending existing Java web apps, and code reuse between server and client-side JavaScript.
Groovy in Mule
This document discusses using a Groovy scripting component in Mule to add a delay to a flow. The Groovy component uses the sleep method to pause message processing for a specified time period. This allows holding the payload for a set interval before writing the file to the outbound location. The example flow reads a file from one directory, uses a Groovy script to sleep for 3000ms, then writes the file to another directory.
UTMessan 2014 - Same .NET code for Windows, Linux, and OsX

OpenNebulaconf2017US: Rapid scaling of research computing to over 70,000 cor...
Since 2008, Harvard Research Computing has undertaken a significant scaling challenge increasing their available HPC and storage from 200 cores and 20TB to over 70,000 cores and 35PB of storage. James will discuss the journey and the highlights of extending the computing to support world class research and education. During the evolution of the computing platforms at Harvard they also helped to support and build the Massachusetts Green High Performance Computing Center which is a dedicated high performance research computing facility in Holyoke, MA. This facility continues to support large scale research computing with sustainable energy and advanced networking. Recently the NESE project (New England Storage Exchange) was funded by the National Science Foundation. This is a multi-petabyte object store that is supported by the existing MGHPCC facility supporting the region. The Data Science Initiative at Harvard has also been recently announced and will require even further advanced computation to support their research faculty. Now as the world takes a grip on "cloud" but more importantly remotely provisioned infrastructure, hybrid models for compute and storage are required along with flexibility to be able to further accelerate science. James will discuss their strategy moving forwards and the current and existing infrastructures in place to allow for seamless provisioning of research computing. Justin Riley Team Lead at Harvard, will follow this talk with a deep technical discussion of the specific implementation of the systems that Harvard are designing in concert with the development teams and leadership at OpenNebula to support research computing to make their platforms more resilient and able to continue to scale.

Why everyone is excited about Docker (and you should too...) - Carlo Bonamic...
In less than two years Docker went from first line of code to major Open Source project with contributions from all the big names in IT. Everyone is excited, but what's in for me - as a Dev or Ops? In short, Docker makes creating Development, Test and even Production environments an order of magnitude simpler, faster and completely portable across both local and cloud infrastructure. We will start from Docker main concepts: how to create a Linux Container from base images, run your application in it, and version your runtimes as you would with source code, and finish with a concrete example.

Docker Overview
This document provides an overview of Docker, explaining that Docker is an engine that sits between the OS and containers to enable rapid application deployment. It describes Docker components like images, containers, and repositories. Images are templates used to deploy containers, with images built from Dockerfiles that define layers. The document highlights that containers are stateless, and various strategies for handling configuration files. It also notes drawbacks like containers being read-only, and tips like using base images and keeping the firewall on.
Docker - A Ruby Introduction
Docker allows applications and their dependencies to be packaged into standardized units called containers that can run on any computing environment regardless of the underlying infrastructure. Containers leverage and share the host operating system's kernel to run as isolated processes, which improves performance and reduces overhead compared to virtual machines. Dockerfiles define the build instructions for container images, while Docker Compose allows defining and running multi-container applications with a single configuration file.
codemotion-docker-2014
This document discusses Docker, an open source project that automates the deployment of applications inside software containers. It begins by describing common problems in application deployment and how virtual machines address some issues but introduce overhead. It then summarizes the history and rapid growth of Docker since its launch in 2013. The rest of the document dives into technical aspects of Docker like how images and containers work, comparisons to virtual machines, security considerations, the Docker workflow, and how Docker relates to DevOps and continuous delivery practices.
Como criar um repositório Ubuntu
The document describes how to create an Ubuntu repository mirror using the apt-mirror tool. It involves configuring where the mirror is stored, how many download threads to use, and which Ubuntu repositories to mirror, such as main, restricted, universe, and multiverse for specific releases. The mirror can then be accessed by client machines by updating their sources.list to point to the mirror server.
Shared Object images in Docker: What you need is what you want.
Docker images require appropriate shared object files (".so") to run. Rather than assume Ubuntu has the correct lib's, use ldd to get a list and install the ones you know you need. This can reduce the underlying images from GB to a few MB.
My early experience with Mirantis OpenStack 6.0
The document summarizes the author's early experience deploying Mirantis OpenStack 6 in a VirtualBox virtual environment on their laptop. It describes downloading the ISO image, running Fuel to deploy 4 VMs in a master-slave configuration with Ceph storage. The cloud infrastructure is deployed, which takes a long time, and then the author accesses the OpenStack portal and launches their first instance, accessing the console.
Introduction to Docker
Docker is an open-source tool that allows users to package applications into standardized units called containers for development and deployment. Containers allow applications to be isolated while efficiently sharing resources on a single Linux host. Docker encourages microservices architecture and streamlines the development lifecycle from development to production by ensuring consistency across environments.
Shipping Applications to Production in Containers with Docker
This document provides an overview and introduction to using Docker in production environments. It discusses how Docker can help with "solved" problems like installing, building, and distributing applications. It also covers important areas for production Docker usage, such as service discovery, orchestration, performance, configuration management, and sysadmin tasks. The document outlines various approaches in each area and notes that there are often multiple valid solutions to consider.
Docker get started
Docker allows packaging applications and dependencies into standardized images for development and distribution. Images act as templates for lightweight containers that share resources and isolate processes. Containers provide scalability, portability across operating systems, and use of common components. Example uses include creating reusable development environments, deploying scalable systems from images, and distributing applications through containers.

How to build your own OpenStack distro using Puppet OpenStack
In a joint meetup with the Sydney Puppet User Group, Michael will demonstrate how to build an OpenStack distro from scratch using the community OpenStack Puppet modules. In an interactive session with the audience, we’re going to pick a Linux distro, use the roles + profiles pattern, use Hiera to populate data, and build up a complete OpenStack cluster inside VMs running the OpenStack Identity, Image, Compute and Networking services. Although there are vendor tools available that can assist with this process, such as Fuel, Cisco OpenStack Installer and Aptira's own Stacktira, understanding how the modules fit together will allow an operator to easily add their own customisations to the any of these systems.
Michael has been working in the cloud computing space, both in a research and enterprise context for several years, with OpenStack production experience stretching all the way back to the third release, 'Cactus'. He leads the Aptira software engineering team in developing deployment and operations tools for OpenStack. Michael is a maintainer of and a driving force behind the most widely used OpenStack deployment tool set, Puppet-OpenStack. He holds a Bachelor of Software Engineering with Honours from Australian National University and is regularly invited back to his alma mater to guest lecture.

Ruby MVC from scratch with Rack
Imagine for a while that Rails wouldn't exist. How would we write a MVC app from scratch?
Rack provides a minimal interface for developing web applications in Ruby. In fact it's the solid foundation of all major Ruby powered web frameworks.
During this talk we will dive deep into Rack. We will see the smallest possible Rack Application and learn how it works, by studying Rack internals. We will grow the Application step by step till we implement it in simple MVC style.
The return of an old enemy
The document discusses the return of an old enemy to the PHP community who has reformed and is now well-organized to improve. It then provides an extensive list of PHP libraries, frameworks, and tools categorized by function to help with improving PHP skills and code quality. The list is maintained by the Awesome PHP project and covers areas like dependency management, frameworks, testing, security, and more.
Rails Girls: Programming, Web Applications and Ruby on Rails
This document provides an introduction to programming, web applications, and Ruby on Rails. It discusses key concepts like HTTP requests and responses, the MVC pattern, and the Rails framework. It encourages learning programming through communication, passion, research, problem solving and patience. The document concludes by recommending resources for learning to code in Ruby on Rails.
Decorator & Presenter Design Pattern
This document discusses the Decorator and Presenter design patterns as solutions to fat controllers and views that contain too much logic. The Decorator pattern allows dynamically adding behavior to individual objects by wrapping them, keeping concerns separated. A Presenter is a specialized Decorator that provides view-specific data. The document recommends using a Presenter/Decorator like Draper to move presentation logic out of controllers and into dedicated objects. This keeps controllers lean and logic out of views.
A taste of Computer Science
Computer science is more than just writing code. So we will take a brief look on some theoretical concepts and problems which scientists study for decades (and maybe never will solve).
Mutation testing with the mutant gem
Mutation Testing is awesome! And it is used to evaluate the quality of existing software tests by modifying the program's source code, based on well-defined mutation operators. Each 'mutated' version is called a mutant and a test which detects the mutation (fail) will kill the mutant. Mutants without failing tests are alive!
Rails - How does it work?
This document summarizes how a basic Rails application works using the example of a Facebook Lite app. The app has models like Post and User, controllers like WelcomeController, views to render the HTML, and a database to store posts. When a request comes in, the Rails router directs it to the appropriate controller action, which gets data from the model and passes it to a view which inserts it into a layout to send the HTML response back to the client.

High performance Serverless Java on AWS- GoTo Amsterdam 2024
Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community. Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. I'll also provide a lot of benchmarking on Lambda functions trying out various deployment package sizes, Lambda memory settings, Java compilation options and HTTP (a)synchronous clients and measure their impact on cold and warm start times.

In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data

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.
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.

Ruby's require, autoload and load methods
- 10. Matz (2011) "discourage the use of autoload" ” [...] autoload itself has fundamental flaw under multi-thread environment. I should have remove autoload when I added threads to the language. [...] I hereby declare the future deprecation of autoload. Ruby will keep autoload for a while, since 2.0 should keep compatibility to 1.9. But you don't expect it will survive further future, e.g. 3.0. I strongly discourage the use of autoload in any standard libraries. https://www.ruby-forum.com/topic/3036681 https://bugs.ruby-lang.org/issues/5653
