Ruby vs. C++ vs. Common Lisp

Unit tests are written in RSpec

We use Ruby for our APIs, coupled with Rails. We also use it for scripting and other open source applications. Check out https://github.com/cotap/stacker and let us know what you think!

Most of our services are written in Ruby. We started out as a Ruby shop, but we're slowly also moving some stuff to Go. We're using Go more and more these days, actually, including some backend services.

Our de facto language, when all other considerations are equal.

Only thing worth noting here is that we saw some major issues with memory swapping on Heroku with Ruby 2.1.2. We weren’t the only ones. So we actually reverted back to 2.0.0. Here’s what happened: . We’re planning to upgrade to 2.1.4 once we’ve had time to test thoroughly.

Main programming language used for all projects around Retrospring

Jekyll is built on Ruby and its plug-ins are written in it and distributed as Gems. Great community!

Nanoc, the static site generator, is written in ruby.

Metaprogramming is necessary for less code.

Ruby is my main programming language for creating classes, modules and methods to fit my plan.

Ruby makes it fun to program! We love the object-oriented capabilities of the language, along with the amazing standard library like Enumerable. The best parts of Ruby? Bundler, RubyGems, and Rails!

The publishing of the docker images is managed by a set of Rake tasks.

7 years of Ruby development experience and project management, primarily with the Rails MVC framework.

I work with Ruby all the time, since 2011.

We use Ruby on Rails for all our web applications. Additionally, we leverage Ruby for some ETL processes and service scripts.

Fun programming, basically. I don't like RoR stack. I prefer pure Ruby App + Rack + (Sinatra/Camping framework)

The main engine of the site is a fork of Toto, a Ruby gem.

Primary server-side engine for the newer code that provides a RESTful interface is all written in Ruby.

Ruby is, with JavaScript, the main language used in DOMScope. With Rails, it handles our product's backend, from the landing page to the communication between our user's devices and their Dashboard.

Several of our applications and API servers are written using Ruby on Rails. Ruby is also used for various infrastructure tools.

For web development

Clean and easy programming language. Favourite language to learn since CSS.

My guilty pleasure and perhas even still a silent love.

Because happiness. Testing via RSpec (mostly model and request specs), Factory Girl for fixtures, VCR for testing API responses, timecop, Redcarpet for Markdown rendering, Intercom gem for posting events.

Rake for deployment to remote and testing server

Used for microservices (incl. an internal Let's Encrypt certificate manager).

We Made the Dashboard with Ruby on Rails.

Primary Language for the Back-end.

Business logic. Scripting.

Microservices, and RabbitMQ Consumers.

Ruby it's our prefered programming language

PRS UI app is built in Rails

Deployment

Rails is built on Ruby, so in the end Ruby is Rails.

expert

We use Ruby on our server in order to run Jekyll.

Most of our applications are written in Ruby/Rails for speed of development.

We are primarily a Ruby shop; our main apps are running on Ruby + Rails, our Slack bot is written in Ruby and our smaller projects are on Sinatra. It makes it really easy for us to re-use code and switch between different projects since they are all on the same language.

For scripting DevOps Tools and internal applications

Mainly worked with Ruby in the context of Ruby on Rails development.

Command-line tools, scripting, prototypes. Occasionally I'll make simple web interfaces, but I find the deployment story for Ruby apps to be more complex than just shipping a jar for personal projects.

When we are comparing Turing complete languages it's not about what compiles faster or to the cleanest machine code, it's about what the developer can think in and write faster, including the availability of libraries. A couple of times I wrote some ruby scripts for this project. I just like the language best for some things. Love the syntax.

Programmer happiness ... duh!

Human readable code, a plethora of Gems, awesome support community. My fav web app language.

Background jobs and tasks

Second choice language

No need for this. We don't use ruby (only in our self hosted gitlab EE)

Core linear algebra and optimization functionality for deep analytics and machine learning

The most latency sensitive parts are written in C++. Due to our interconnected services architecture, we use either Python or C++ for each service, with the performance critical parts being C++14.

Our online judge, 'Evaluator', is written in it.

legacy part

The Game Pencil Engine Editor is coded in C/C++.

Used in backend and clients for performance heavy tasks.

Performance, zero-overhead abstractions and memory safety of the modern C++ language make this the perfect language for the project.

High performance

The main programming language of ApertusVR. C++11 & CMake provides multi-platform targeting. The architecture is modular.

Used to write PHP extensions - AZTEC Decoder - License Driver scan - Axis2/C to PHP wrapper and Job-scheduler - Barbershop

std::cout << "Hello World!" << std::endl;

C++ is used in Shiro (https://github.com/Marc3842h/shiro).

C++ is a high performance, low level programming language. Game servers need to run with fast performance to be able to reliably serve players across the globe.
