RubyGems were developed to simplify and accelerate the stages of the application creation deployment and library connection. Utilizing this package manager for Ruby saves you time as you get ready-made solutions to almost any task instead of writing the functions from scratch. Each gem contains a particular element of functionality including all related files. Unfortunately they aren structured in any way so in order to find ruby gems it better to use a regular search engine and the required key words (check GitHub s ). Our dedicated development team also actively employs Ruby Gems in the process of software development. Here is the top of the most popular and useful ruby gems according to our experience GeoCoder s . Being able to connect through itself over 4 APIs this Ruby gem implements both the direct and reverse geocoding by IP address geographical coordinates and even real physical addresses (e.g. the address of the street). Bullet s . The most downloaded Ruby gems out there. It was initially created with an intention to boost software performance. It does so by decreasing the total amount of client-server requests. Basically Bullet tracks the N+1 cases of requests and notifies the developer when other tools can be used instead (e.g. cache counter). Pry s . We rmend to simplify the bug fixing procedures for your RoR-based application with the Pry gem which is a more advanced alternative to the standard IRB wrapper. ActiveModelSerializers s (which starts lagging while processingpound documents) and uses caching. Fast JSON API s . Fast JSON API wille in handy when you need fast serialization of software code. It works much faster than Wicked PDF s . This gem is working alongside with wkhtmltopdf s and helps realizing an interaction with the DSL generator. Devise Masquerade s . This Ruby gem helps developing multi user apps. In particular youll be able to test your app from the perspective of users with different levels of access. Devise s . Based on the MVC model the Devise gem can provide secure user authentication and session management. Letter opener s . If you need to create a newsletter mechanism to send notifications to all users that launched your app this gem will help you do that much easier you won need to integrate and configure your own SMTP server. Money Rails s . If you are planning to integrate your app with Ruby Money this gem wille in quite handy. Pundit s . A tool that allows defining different levels of access to the app functionality according to the rights of an authorized user.
What can Python do?
It nice that you want to know the applications of python before learning it. Python is a general purpose programming language. So it has vast number of applications in Artificial Intelligence Data analytics Web development 3D gaming and graphics Robotics etc. It relatively easy programming language to learn with simple syntax. No wonder it has be favorite of techmunity. Therefore it has been used in variety of fields. You can do software development using python. Popular applications like YouTube BitTorrent Dropbox have been using python heavily to build their functionality. A lot startups have been using python to build mobile applications. A popular app like Instagram which is mostly built using python. Yes you can develop websites using Python. You can use web frameworks like Django Pyramid Flask etc to create back end logic. Python has also standard library supports for internet protocols like HTML XML JSON etc. that are used in develop front end logic of the application. Data Science New buzzword in tech industry. Python has libraries like Pandas and NumPy that are used in Data Science and Data Visualization. They have capability do a lotputing and other host of other technical things. AI and ML have be hot fields in today world. A lot people have heard and used these words but they really don know what they mean at deeper level. Python provides library called Scikit-Learn library to write machine learning algorithms in python. If you are more into neural networks then python has Tensorflow to implement neural networks. You can also build Operating Systems using python. You heard it right. Although python is not known for its OS building capabilities I just wanted you to know that it is that robust. Moreover it is platform independent so applications build in python can run on any OS platform. Python is one of the best languages if you want to learn how to code. It usually better if you start with simple and versatile language like python. Now there are many resources that teach you python. I havee across Edu4Sure python course as one of the best courses to learn python. They have good mentors with strong focus on hands on learning. I hope this helps you. Best wishes!
