What is Passenger? 

Passenger is a web server and application server, designed to be fast, robust and lightweight. It takes a lot of complexity out of deploying web apps, adds powerful enterprise-grade features that are useful in production, and makes administration much easier and less complex. Phusion Passenger supports Ruby, Python, Node.js and Meteor, and is being used by high-profile companies such as Apple, Pixar, New York Times, AirBnB, Juniper etc as well as over 350.000 websites.

Main features:

  • Simple configuration
    • Simultaneously run and manage all your Ruby, Node.js, Python, and Meteor apps, as well as APIs and microservices, on a single Passenger instance.
  • Consolidated overviews
    • Simplify your DevOps logistics by managing and monitoring multiple apps at once.
  • NGINX and Apache integration
    • Passenger’s installation process includes either NGINX or Apache installation to reduce work and moving parts on your end.
  • Supported technologies
    • RubyGem, APT and YUM packages; Puppet, Chef, and Ansible recipes; Docker integration; and more are available.

What's new in version 5.1.8?

  • APT Nginx package to 1.12.1
    • The APT Nginx package that was provided for older distributions (Ubuntu Xenial / Debian Jessie and below) was stuck at Nginx version 1.10.3 due to incompatibilities in the module set that those distributions use. Updated module versions have solved these issues, so we've upgraded the package to the latest stable Nginx (1.12.1).
  • Webpacker asset support
    • Passenger Standalone now automatically uses Nginx to serves static asset URLs that conform to the webpacker gem format.
  • Improved logging
    • Log format changed to be shorter and more informative. The new format significantly shortens the thread ID, and includes the message's (abbreviated) log level so that it's a lot easier to filter through messages.
  • Various fixes
    • Fixes a potential use-after-free bug when reporting usage data to the Phusion licensing server. This bug only occurs when Passenger Enterprise is running inside a container.
    • If configured to listen on a Unix domain socket, properly cleans up this socket on Nginx shutdown (a regression from 5.1.6).
    • Fixes the --max-requests option when using the builtin engine (a regression from 5.1.4).

Topic: "Docker + GPU. Not about mining."

Anna Shcherbinina

Just before Christmas we launched a new body-measurement feature for our shapify.me project. A person goes into the 3D booth, gets scanned, and the body-measurements are calculated with the 3D scan data. We couldn't avoid using a GPU with these calculations.

How to install this branch of processing into our elegant scaling pipeline? When you're dealing with 3D scans you should remember two things: it's expensive and time-consuming. By the way, its workload fluctuates throughout the days. The easiest solution for us was to use Docker.

This speech is not about mining, but the most helpful articles for us were ones such as "Building your own mining farm". That's because we use quite a similar infrastructure.

GPU, Docker, scaling. What we achieved, where we failed, and what it became of it in the end is all included in my speech.

Topic: "A polyglot's view of Ruby on Rails"

Leonid Shevtsov

Nowadays, it's hip to switch from Rails to other languages and frameworks. Leonid, too, has abandoned Rails, played the field a bit, and has come around to occasionally but consistently picking Rails for some projects. What's the modern reason to use Rails? What are the strengths of Ruby and Rails and how to build upon them? When you should really jump to some other platform? Let's answer these questions in a true Ruby meditation.

Topic: "Project development - preparing hell dish together"

The recipe is averaged, because of many variations. We take some Ruby code and add Rails magic, Postgresql on top. Add Docker for viscosity. Then put this on AWS EBS pan and start frying. It's all roasted until burning deadlines and generously watered with bugs, serves to the customer. They start eating. Eat and whisper: “This is an awesome product!”. At the same time, he forehead is sweating. Kindly offer to fix bugs, but we refuse and put them in JIRA. Do I need to talk about what kind of feedback comes then? Tasks with such recipes, that double estimated.
