The right choice of navigation is a basis of designing applications on React Native. It largely defines the project structure and the performance. At the moment, there are two types of navigation: native and JavaScript-based.
React Native is, perhaps, the most interesting and fast-evolving platform. Today you can create a new project based on its latest version, and in just a few months it will get outdated for a few releases. And if a year ago React Native was quite a raw product, now there are lots of plugins for dealing with native components as well as common React components.
In the previous articles of the series we decided on the required playground functionality and prepared a [runtime infrastructure for game bots and sandboxes](https://anadea.info/blog/it-duel-2017-implementation-part2-digital-ocean-droplets-and-dokku-setup). It's time to actually program the game engine.
If you happen to own or work for a software enterprise, you possibly have been asked a hundred times if you are agile. Although initially intended to upturn the accessibility of software development teams, in the recent times 'agile' has emerged as the default team-based working model for all enterprises, irrespective of their size, industry and location.
In the first article of the series, we recalled the rules of the game and the technical characteristics of the game engine. Now, let's describe how to use DigitalOcean and Dokku to allow players to write a bot in multiple languages, while having guaranteed equal resources in runtime and a pleasant deploy procedure.
Programmers strive to write simple and understandable code. The less code is written, the less likely it is that there is an error in it. Scala offers the ability to write even more concise code and rely on the help of the compiler.
The history of Java began in 1995, when the first version of this programming language was released. "Write Once, Run Anywhere" (WORA) was the slogan of the new language. This meant that Java was not just another programming language.
Self-storage facilities are companies that provide storage space (lockers, containers, garages, etc.) by lease. Often, self-storage companies have multiple locations with a few hundred of units in each. It is quite a big business and it requires management software to keep all units under control. There is special software for their needs.
Rspec is an awesome thing that was created for ruby community. Most of us write tests. However, sometimes in large projects our test becomes really slow. So, each launch of the test really hurts and it does not meter whether you launch your test before commit/push or on CI. When your test suits pass over 30 minutes - something definitely went wrong.
Sometimes, when you are working with a large codebase, your `routes.rb` files grow really fast and become very dirty.There are several things that make your routes file bigger:* Customization of devise;* Specific gems that mount additional routes (Active Admin, ActionCable);* Sidekiq + SidekiqWeb + Basic authentication;* Namespaces with APP or API.
Сarrierwave is a popular image upload gem used by the Rails community to upload files to the server.Recently I had a task to upload two types of images into the application. Under the hood,the only difference between them was the target directory on the server. Sounds pretty simple, right?
In the world of front-end development, things are a bit complicated. New frameworks appear all the time, which provides both opportunities and challenges for developers. The situation has become better in the past few years but it's still confusing. Polymer, Aurelia, Sencha, Webix and so on - what's behind all those names? How and when should you use them?
