Building Reusable Components with Ruby Rack: A Practical Guide to Middleware in Rails
Why Use Ruby Rack? To implement middleware in a Rails app, create a new class in the app/middleware directory. The class should implement the call method, which takes the env parameter representing the current request environment. The call method should return an HTTP response.
A Beginner's Guide to Ruby Metaprogramming: Using Simple Examples and Tips to Enhance Your Code
Metaprogramming is a technique that allows you to write code that generates other code at runtime. This is done by using Ruby's reflection capabilities to introspect on classes and objects, and then using this information to dynamically generate new code. This can be a powerful way to write more flexible, reusable, and maintainable code.
Metaprogramming in Ruby can be divided into two categories: class-level and object-level metaprogramming. Class-level metaprogramming involves adding, removing, or modifying methods and other behavior at the class level. Object-level metaprogramming involves adding, removing, or modifying behavior at the instance level.
Ruby Modules and Extend, Include, and Prepend keywords
A module is a container of Ruby code that can be used to group related methods, classes, and constants. Modules provide a way to organize and reuse code in Ruby, making it easier to maintain and extend applications.
Modules can be thought of as a package of functionality that can be included or extended in other classes. Unlike classes, modules cannot be instantiated or inherited. Instead, they are used to mix in functionality to classes.

300,000 Downloads and a Few Mistakes: My Journey as an Android App Developer
Around 2010, I had a lot of ideas which I wanted to implement as mobile apps. So, for me, it was easiest to do that with Android and Java programming languages. I had the tools and free time, so I made a few apps and games. They were published on Google Play at the time, but later, after a few years, they were removed because I didn't have time to update/upgrade them. In total, those apps had around 300,000 downloads, and I did some interviews for web portals to present my apps. There was also some money from South Korean Telecom and from some advertising platforms at the time. It was a nice experience.
Debunking the Myth: Ruby on Rails and the Truth about Demand for Developers
Boys and girls, it's not true that Rails is still in big or any significant demand! All the tweets, statistics, and blogs people write lately and share are not so true. This is so obvious, but it looks like lying is cool these days, or we are desperate, so some of us must use lies?
