Please listen up!
I need assistance with preparation for coding session
The CodeSignal screen is meant to test general coding ability. 
I’ll be asked to implement a simple coding project from a spec and develop it to the point that it passes some tests. 
I should prioritize 
a) writing code that passes as many tests as possible and 
b) progressing through all four levels quickly. 
It'll essentially be a toy simulation of an app that won't require anything except the standard library of chosen programming language. 
Note there's no framework/UI or anything similar — basically, it's like the core business logic of an app, but nothing else. 
It won’t test detailed knowledge of algorithms, compute systems, or machine learning.

How to create a Ruby gem that adds Rake tasks

Create a gem

One way to do this is to use bundler to scaffold our gem:

bundler gem my_gem

Add rake tasks to our gem

I prefer to put tasks meant to manage the gem itself in lib/tasks, and tasks the gem is meant to provide to gem users in lib/my_gem/tasks.

Ruby and Postgres Regular Expression Syntaxes

Ruby's regular expressions are unusually powerful. Postgres' regular expressions are not as powerful, but they come close; close enough that it's possible to do many pattern-based queries and string transformations entirely in a query.

And sometimes, it's very useful to have a single regular expression that works

How to scale out a Phoenix application with websocket

Foreword

It's relatively easy to scale out stateless web applications. You often only need a reverse proxy. But for those stateful web applications, especially those applications that embeds websocket services in them, it's always a pain to distribute them in a cluster. The traditional way is introducing some external services like Redis to handle pubsub, however, in such way, you often need to change your code. Can Erlang/Elixir, the "concurrency oriented programming languages", best other languages in this use case? Has Phoenix framework already integrated the solution of horizontally scaling websocket? I'll do an experiment to prove (or disprove) that.
