This post covers how to register an ethereum name service (ENS).
Most people are aware of how to register a Domain Name Service (DNS). If you’ve ever registered a domain, like usefulprogrammer.org, then you have utilized the DNS system. Anyone who has a .com or a .net website has registered a site with a DNS.
The ENS is registering a name server with the Ethereum blockchain. Let’s see how to do it…
Step 1:
…the impediment to action advances action…
Today I solved an error in my Ruby on Rails application.
The problem was that the reset password process led to the root path, rather than the reset password Devise view. This was an error in the production version of the application, which is deployed on Heroku, and NOT on my local development version.
My problem was solved by adjusting the config/environments/production.rb file.
I had this:
config.action_mailer.default_url_options = { host: 'windaily.app' }
Which needed to be set to this:
config.action_mailer.default_url_options = { host: 'https://www.windaily.app' }
This was a bit of a tough one to figure out because I wasn’t getting any error messages. It just didn’t work.
But now the production app is working with the Devise :recoverable setting implemented.
I came across this issue while upgrading an older version of a Ruby on Rails app. The error caused my continuous integration to fail.
ActionView::Template::Error (Autoprefixer doesn’t support Node v0.10.48. Update it.)
The way I solved it was to re-initialize the Node object in the application.js file.
module AppName
... # removed for brevity
end
## TODO: Check to see if ExecJS has fixed this bug. If so, delete the code below and check SemaphoreCI
module ExecJS
module Runtimes
Node = ExternalRuntime.new(
name: "Node.js (V8)",
command: ["node", "nodejs"],
runner_path: ExecJS.root + "/support/node_runner.js",
encoding: 'UTF-8'
)
end
end
This is a hackey way to solve this problem. With luck, ExecJS will update their gem in the future and this code can be removed. I’ve added a TODO here so I can remember to fix this down the line (note: if you run rails notes, you can see a list of TODOs in your app.)
If there are any early stage programmers that want to work with me on a open source project, here are some issues. I’d love to see some Pull Requests from the usefulProgrammer community:
In this tutorial we set up a template engine called Pug. This is one part of many making up the Advanced Node and Express section. This section makes up part of the Quality Assurance Certification. I want to say a big thank you to FreeCodeCamp (www.freecodecamp.org) for the curriculum. My goal with these videos is to support early stage programmers. I hope that these videos help you to learn faster and understand more fully. For me, learning this was difficult so I hope this makes your life less difficult. Thank you for watching.

In this APIs and microservices project, we do part one of building an exercise tracker API. This is the fourth part of four sections where we work to achieve our APIs and Microservices Certification. This video constitutes one part of many where I cover the FreeCodeCamp (www.freecodecamp.org) curriculum. My goal with these videos is to support early stage programmers to learn more quickly and understand the coursework more deeply. Enjoy!

In this Quality Assurance and Testing with Chai tutorial we run functional tests using a headless browser part II. This is another tutorial where we implement a headless browser using Zombie.js in a Node.js application. This is one part of many sections where we work to achieve our Quality Assurance Certification. I want to say a big thank you to FreeCodeCamp (www.freecodecamp.org) for the curriculum. My goal with these videos is to support early stage programmers. I hope that you all can learn more quickly and understand the coursework more deeply than I did when I was at your stage. Thank you for watching.

In this video I do the Codility_ project called CyclicRotation. Codility_ is a platform that gives us tools to become better programmers. It actually appears that if you develop your skills on this platform, it could lead to a job there too.
Here’s the playlist for all my Codility_ videos:

In this Quality Assurance and Testing with Chai tutorial we run functional tests using a Headless Browser. This tutorial for setting up and running Zombie.js. This is one part of many sections where we work to achieve our Quality Assurance Certification. I want to say a big thank you to FreeCodeCamp (www.freecodecamp.org) for the curriculum.
