Supporting API conventions for client like reactjs can be quite tricky. This post talks about approach to make APIs accessible using snakecase or camelCase.
Deploying a Rails app with Webpack asset management on Heroku can be tricky. However, Heroku provides lifecycle hooks on its NodeJs buildpack that will help make this easier.
Erlang is a powerful concurrent programming language that has Processes as a first class citizen. These are isolated by default. Just like in Unix, these processes can communicate using Signals. In this post we will see how to achieve that in Elixir.
Elixir, built on the battle-tested Erlang VM, is a language that has concurrency as its core ideas. I will introduce a monitoring utility shipped with the VM that helps us visualize HTTP requests.
Rails 5 has a new feature added to ActiveRecord that makes working with batch data much more efficient. The `Model.in_batches` function passes a batch of records wrapped inside an ActiveRecord collection.
Autoprefixer is a tool that adds vendor prefixes to CSS based on the usage patterns and current state of support. This results in clean code and smaller CSS files.
Ruby's TracePoint API is very powerful for building custom profilers. As the final post of the DIY CPU profiler series, this post will introduce how to get method runtime statistics and generate relevant graphs.
Ruby's TracePoint API is very powerful for building custom profilers. In this post I will talk about hooking into Ruby code execution life cycle using this API
Ruby's TracePoint API is very powerful for building custom profilers. In this post I will talk about Wall time and CPU time, and how to measure them for Ruby programs.
Ruby's TracePoint API is very powerful and allows us to write custom profiling code without slowing down the execution of programs. In this post, I will introduce CPU profiling and 2 strategies to write one.
Traditionally, Rails 3.x and above come with Sprockets and asset management functions. However, using a JavaScript or CSS library with Sprockets means we'd have to roll them into gems with a specific directory heirarchy. Instead, we can leverage Bower to handle that for us.
JSON schema can help bring order to handling complex JSON interactions in APIs. For instance, you can avoid checking the types of incoming JSON and rely on JSON schema to do the validation. This post talks about similar usecases.
Interacting with complex web forms tends to become hairy pretty quickly. Using Form or Service objects to abstract out the complexity can help wrangle complexity. This post talks about how we use them to make code simpler.
There is a proliferation of high resolution screens on mobile devices, and non-optimized images tend to look ugly on them. This post introduces ways to use optimized images for use in HTML on high DPI screens.
Ruby 2.0 and above has in-built support for DTrace hooks. This lets us profile Ruby programs. In this post, I'll go into the details of the features of DTrace.
Ruby 2.0 and above has in-built support for DTrace hooks. This lets us profile Ruby programs. In this post, I'll introduce DTrace and how to add DTrace probes to a Ruby program.
