[Js hcm] Deploying node.js with Forever.js and nginxNicolas Embleton
You have a project in Node.js and you wonder how to make it run on your server? A real "production" server?
You have some application and you want to ensure that it will run - without downtime, that you can easily update - without downtime, and that you can scale it over multiple webservices as a load Balancing?
We will cover that by using:
- Nginx
- Forever.js
- Node.js
Node is a JavaScript runtime environment that allows JavaScript to run on the server. It uses Google's V8 JavaScript engine and allows developers to build fast and scalable network applications using JavaScript. Node installs with NPM (Node Package Manager), which is used to install dependencies and share JavaScript code as reusable modules. Many modern web development processes use Node and NPM together to compile assets, run tasks, and share code.
This document discusses node.js production site architecture. It begins with an introduction to Ben Lin and his work with node.js projects. The rest of the document outlines best practices for running node.js in production, including using services like Monit and Forever to monitor node processes, using Nginx for load balancing and static file serving, scaling node.js applications by splitting components across multiple servers, and deploying node.js applications with tools like SSH, Git, AWS, and Heroku. The document concludes with some tips for configuring file limits and handling uncaught exceptions in node.js.
Vagrant is an open source tool that allows users to create and manage virtual machine environments. It provides a command line interface to define VMs using a Vagrantfile configuration file and control their lifecycle. Vagrant aims to simplify setting up reproducible development environments by automating the configuration of VMs and removing the need to install software locally. It supports provisioning VMs automatically through scripts and managing multiple coordinated VMs through a single configuration.
Vagrant allows users to easily create and configure virtual development environments. The document outlines a 5 step process to get started with Vagrant: 1) select a virtualization provider like VirtualBox, 2) install Vagrant, 3) download a virtual machine image or "box", 4) initialize and start the VM with Vagrant commands, and 5) log into the VM via SSH. It also discusses additional features like version controlling Vagrant files, customizing the VM, using multiple VMs, and provisioning VMs with tools like Puppet, Chef, or Ansible.
The document discusses various ways to tune Linux and MySQL for performance. It recommends measuring different aspects of the database, operating system, disk and application performance. Some specific tuning techniques discussed include testing different IO schedulers, increasing the number of InnoDB threads, reducing swapping by lowering the swappiness value, enabling interleave mode for NUMA systems, and potentially using huge pages, though noting the complexity of configuring huge pages. The key message is that default settings may not be optimal and testing is needed to understand each individual system's performance.
The slides describe the Ruby debugger called "byebug" and it's integration into the YaST installer which is used in openSUSE and SUSE Linux Enterprise products.

This document discusses using a virtual machine to run Linux on Windows for Drupal development. It recommends installing virtualization software like VirtualBox or VMware and then installing a Linux distribution within the virtual machine. This allows replicating the hosting environment and provides benefits like familiarity with Linux, web hosting, and virtual private servers while still using Windows. A demo shows faster page loading from a Linux virtual machine compared to using XAMPP on Windows alone.
This document provides an agenda for a talk on Apache Mesos, a distributed systems kernel that provides resource management and helps to abstract cluster resources. The talk discusses why distributed computing is hard, how Mesos helps by turning servers into a single large computer and improving multi-tenancy. It also covers Mesos history, how it works, examples of Mesos in production use, and alternatives to writing custom frameworks like Marathon.
This document summarizes configuration management tools and introduces Ansible. It notes that Puppet and bcfg2 are pull-based with custom authentication and performance issues, while Ansible is push-based using SSH keys, fast with no daemons. Ansible can be installed with pip and used immediately in one-shot mode or with playbooks for complete configuration management. Playbooks allow defining collections of actions like one-shot mode with notifications. The document concludes that Ansible can go from zero to production in minutes with no custom setup or dependencies.
This is a presentation I prepared for a local meetup. The audience is a mix of web designers and developers who have a wide range of development experience.
Node.js is a JavaScript runtime environment that allows JavaScript to be run on the server side. It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient for data-intensive real-time applications that require persistent connections. Some common uses of Node.js include real-time web applications, building APIs, and handling multiple connections at once without creating new threads. The document discusses why Node.js is well-suited for applications that require maintaining persistent connections from the browser to send updates in real-time using techniques like long-polling.
Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine that allows for asynchronous and non-blocking code execution.

This document provides a summary of the film "Into the Wild" based on the true story of Christopher McCandless. It discusses how McCandless graduated from university but rejected modern society to live off the land in Alaska. He destroyed his credit cards and gave his money to charity in search of ultimate freedom and independence. While in Alaska, he lived alone in the wilderness and kept a journal. In April 1992, he hitchhiked to Alaska where he was last seen alive on April 28 before apparently starving to death after ingesting toxic seeds. The film had a profound impact on viewers and inspired many youth to appreciate nature.

The document discusses Walter White and his alter ego Heisenberg from the TV show Breaking Bad. It describes Walter White as a mild-mannered high school chemistry teacher who is financially unstable and dissatisfied with his life. His alter ego Heisenberg is the ruthless persona he takes on when entering the drug trade, making the purest meth ever seen. The document analyzes how Walter White transforms into Heisenberg through changes in look, attitude and taking on the name of the famous physicist to portray himself as a scientific genius within the criminal world. It also briefly discusses how Walter White relates to other fictional characters with dual personalities and how the show uses mirrors and reflections as symbols.
This document lists 5 sources about Christopher McCandless: a book about McCandless called "Back To The Wild", a website about his life and nickname "Alexander Supertramp", an article debating whether the bus where he died in Alaska should be removed, a 1993 magazine article about his death, and an interview with the actor who played him in the movie "Into the Wild".
The document discusses the freedom of traveling alone on the open road and escaping from obligations and oppression. It also discusses the importance of facing challenges alone and testing oneself through difficult experiences. Several passages discuss the importance of finding truth and joy in life through appreciating one's surroundings rather than relying too heavily on relationships with others.
Breaking Bad is a review that discusses the main characters of the show and their families. It also mentions how some of the Breaking Bad actors have been nominated for and won Emmys for their roles. The review is written by Aleix Mando and ends by thanking people for watching.
Breaking Bad: Todos los personajes Parte 1alberts1999
Walter White and Jesse Pinkman are the main characters who get involved in manufacturing and distributing methamphetamine. They must avoid detection from Hank Schrader, a DEA agent and Walter's brother-in-law, and Gus Fring, the leader of a drug empire. The document provides a list of over 20 characters involved either primarily or secondarily in the show's plotlines about drugs.
This document provides a critical analysis of the book and film "Into the Wild" about Chris McCandless from psychoanalytic, Marxist, and existential perspectives. It analyzes McCandless' personality and motivations for rejecting societal expectations using the theories of displacement, attribution, fear of intimacy, classism, and existential bases like awareness, self-consciousness, and anxiety. It compares his journey to self-reliance ideas from American authors like Emerson and Thoreau.
The diary entries document Chris McCandless, also known as Alexander Supertramp, as he ventures into the Alaskan wilderness alone to live off the land. In the first entry, he expresses his excitement to reach Alaska and begin his great adventure living independently in nature. In later entries, he discovers an abandoned bus to use as shelter, hunts and kills a moose, but then struggles with hunger as his luck changes. In the final entry, on his 100th day in the wilderness, he has become too weak to leave and realizes he now faces a serious threat of death without medical help.

The show is set along the USA and Mexico border in New Mexico and tells the story of Walter White, a high school chemistry teacher who turns to manufacturing methamphetamine to secure his family's financial future after he is diagnosed with lung cancer. The main characters include Walter White, Jesse Pinkman, Skyler White, Walter White Jr., Hank Schrader, Saul Goodman, and Gus Fring. While not available in Catalan or Spanish, Breaking Bad is widely recommended for its gripping plot and character development.
Giving bad news to patients is a complex communication task that requires special skills. Doctors must [1] prepare thoroughly, [2] address the patient's emotions with empathy, and [3] develop a management plan with the patient's input. Strategies like SPIKES provide a framework to [1] set up the conversation, [2] assess the patient's perspective, [3] obtain their invitation to know, [4] give knowledge and information, [5] address emotions, and [6] summarize and develop a strategy. Managing patients after a pregnancy loss also requires sensitivity, as they experience grief, guilt, and isolation.
Breaking Bad is an AMC crime drama television series created by Vince Gilligan that aired from 2008 to 2013.

Amarelo – Alegria, Felicidade, Energia, Precaução e Atenção
Azul – Confiança, fé, inteligência, sabedoria
Vermelho – Energia, força, poder, paixão, Amor,
Verde – Natureza, Crescimento, Fertilidade, Harmonia, Dinheiro
Roxo – Luxuria, Realeza, Nobreza
Laranja – Entusiasmo, Estimulo, Sucesso
Preto – Poder, Elegancia, Morte, Mal
Branco – Pureza, luz, Bondade,
Wilson finaliza a apresentação falando sobre o seriado Breaking Bad que foi gravado utilizando a teoria das cores (cuidado – tem Spoiler).
This document discusses how to give patients bad medical news. It notes that bad news can drastically alter a patient's view of the future and cause emotional responses like denial, despair, anger, bargaining, and depression. Giving bad news is difficult for doctors as it undermines their role as healer and upsets both them and the patient. The document recommends being direct with patients about their diagnosis, treatment plan, and prognosis while allowing them to process the information at their own pace. It provides guidelines for opening, exploring, and closing the difficult conversation with empathy, honesty and support.
Node.js is a compelling platform that is quickly spreading from startups to the enterprise. As a .NET developer, why should you learn Node.js and where do you start? You will come away from this talk with the evidence and tools you need to be a productive Node.js developer. We'll walk through creating, debugging, and deploying a Node.js project to Microsoft Azure using the Node.js Tools for Visual Studio. We'll also look at popular frameworks and modules, and other learning resources.
In this presentation, I'm covering the topics
Node Package Manager (npm)
initializing a node project
dependencies and dev dependencies
Installation, listing and uninstallation of node packages
Importing of modules
The document discusses dbdeployer, a command line tool for deploying and testing MySQL database topologies. It can deploy single or multiple MySQL instances, as well as complex topologies like replication, group replication, and multi-source replication with a single command. Dbdeployer aims to make deploying and testing databases fast and easy by avoiding repetitive manual tasks. It has features for upgrading and importing existing databases.
Robbie Jerrom presents on Puppet, an open source configuration management tool. Puppet takes a declarative approach, allowing users to define what a system configuration should be rather than how to achieve it. Everything in Puppet is defined as a resource like packages, files, and services. Puppet uses a client-server model to manage configurations across multiple systems from a central Puppet master. It provides an easier way to deploy and manage software compared to traditional scripting approaches.

Robbie Jerrom presents on Puppet, an open source configuration management tool. Puppet takes a declarative approach, allowing users to define what a system configuration should be rather than how to achieve it. Everything in Puppet is defined as a resource like packages, files, and services. Puppet operates in a client-server model and uses modules to define common configurations that can be applied across nodes. It aims to provide an easier way to deploy and manage software compared to traditional script-based approaches.
This document provides guidance on setting up a minimal OpenStack cloud in one's basement for learning and experimenting purposes. It recommends starting with only the core services like Nova, Glance, and Keystone. Example steps are given to install OpenStack on a single node, create a security group to allow SSH, boot an Ubuntu image as a test server, and connect via SSH. Advanced networking with Neutron is not required initially. The document also outlines some additional OpenStack services that can be added later to expand the cloud once the core is established.
Docker Compose allows developers to define and run multi-container Docker applications. It helps coordinate multiple containers to work together by defining them in a single compose file. This avoids the complexity of using raw Docker commands. Compose files define services, their images, dependencies, volumes, ports, etc. Compose then automates setting up and running the entire application with a single command. This provides an isolated development environment approximating production. It enables features like continuous integration testing against real services rather than mocks. Overall, Docker Compose improves the developer experience by simplifying and streamlining local development and testing of multi-container applications on Docker.
Cypress is an open source, front end testing tool built for modern web applications. It uses JavaScript to write automated end-to-end tests that run directly in the browser engine. Unlike Selenium which runs outside the browser, Cypress operates inside the browser to listen and modify behavior. Cypress makes testing simple through its intuitive API, fast speeds, and ability to work on any frontend framework. The document outlines Cypress' architecture, features, limitations, installation process, project structure, and how to write tests using constructs like describe, it, before, and assertions.
This document summarizes John Griffith's presentation about using Docker volume plugins with OpenStack Cinder block storage. Some key points:
- Griffith developed a Cinder volume plugin for Docker to provide persistent block storage to containers. This allows using existing Cinder backends without vendor lock-in.
- He demonstrated deploying a Swarm cluster on OpenStack using docker-machine and the built-in OpenStack driver. The Cinder plugin was installed on each node to enable volume provisioning.
- As a proof of concept, Griffith deployed a Redis service with a Cinder-backed volume for persistence, and a web frontend service, demonstrating stateful applications in containers with Swarm orchestration and Cinder storage.

Parallelizing CI using Docker Swarm-ModeAkihiro Suda
Presented at Open Source Summit Japan (http://sched.co/AOmo)
- - -
Slowness of CI is a critical issue in software development, because it discourages engineers from writing tests, and hence deteriorates the quality of the product.
In this presentation, Akihiro Suda will talk about how to accelerate CI by executing test functions in parallel, across a Docker Swarm-mode cluster.
One of the major challenges was the nonuniformity of the makespan. e.g. some chunk of test functions can take 30 minutes, some chunk can take just 10 seconds...
So, he mitigates such a nonuniformity by randomizing the composition of chunks of test functions.
As a result, for example, the integration test of Docker itself that had taken more than 80 minutes can be finished in 4 minutes, with 10 Docker Swarm-mode nodes.
This hack can be easily applied to CI of other software as well.
A presentation given at DeveloperWeek in San Francisco by Zack Argyle. It goes through important concepts in building out reusable React components, releasing it to Github, and publishing it to NPM. There are best practices and suggestions with an example component.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Friday, April 20, 12
2. ME
• Co-founder and Chief-Programmer of AskYourUsers.com
• @chrisbumgardner and cbumgard@gmail.com
• github.com/cbumgard
• My first ‘real’ production web app in Node.js
• Invite only beta, going live this week.
Friday, April 20, 12
3. THE STACK
• Node.js
• Express
• MongoDB
• Redis
• Apache Solr
• Nginx / Ubuntu 11 / 2 x LinodeVPS
Friday, April 20, 12
4. CONFIGURATION
• Partition your configuration by environment.
• E.g. Config[process.env.NODE_ENV]
• We have 3 environments: 2 dev and 1 production.
• Environment is top-level namespace (‘dev’,‘production’, etc)
for everything, including db. Keeps worlds from colliding.
• Makes life easy
Friday, April 20, 12
5. CONFIGURATION 2
• dev env 1: sessions in memory, clean db each start.
• dev env 2: persistent sessions & db, ssl.
• production env: aggressive caching, ssl, live payments, clustered,
fancier logging (more later), email/sms notifications.
Friday, April 20, 12
6. LOGGING
• Log early and often.
• Using Winston with the MongoDB transport.
• MongoDB logging: fast writes; pass json objs in log msgs; easy
ad-hoc queries; easy lru via capped collections.
• Client logging from browser: caught and logged to Google
Analytics as custom event. Easy monitoring/aggregation.
Friday, April 20, 12
7. DEPLOYMENT
• Custom CI system in node that responds pushes to github
• Post-Receive service hook. Github POSTs to us after a push.
• CI will pull code if it’s the right branch (say ‘staging’), restart,
and send SMS.
• Easy and low touch.Texts from your node are nice.
• Refactoring into a more modular/decoupled hook.io system.
Friday, April 20, 12
8. ALSO
• In development: use ‘nodemon’ to start server.
• Watches all files in project and restarts node if anything
changes.
• Great with persistent sessions, test changes immediately.
• In production: use ‘forever’ to start server as daemon. Restarts
node automatically if it crashes. Runs in background. Nice CLI.
Manages stdout/stderr logs.Tracks multiple processes.
Friday, April 20, 12
9. CLUSTERING
• In production, use ‘cluster’ module to fork separate node per
core
• App-wide initialization: if cluster.isMaster
• Otherwise per-proc initialization
Friday, April 20, 12
10. DEPENDENCIES
• Found out the hard way to control node, npm, and dependent
module versions.You don’t want to push a change to
production and have npm barf. No bueno.
• Keep them the same on all machines.
• Use npm in development.
• In production I recommend bundling/controlling the deps and
versions explicitly.
Friday, April 20, 12
11. PROFILING
• ‘ab’ is your friend.
• don’t forget ulimit.
• Joyent has great video on profiling with dtrace.
• ‘nodetime’ module: great in development, but my server got
hosed when I tried it in production. Probably user error.
