Deploying a Production ready Django app on AWS

In this tutorial, I will be going over to how to deploy a Django app from start to finish using AWS and EC2. Recently, my partner Tu and I launched our app Hygge Homes (a vacation home rental app for searching and booking vacation homes based off Airbnb) and we wanted to share with other developers some of the lessons we learned along the way.

Following this tutorial, you will have an application that has:

• An AWS EC2 server configured to host your application
• SSL-certification with Certbot
• A custom domain name
• Continuous deployment with Github Actions/SSM Agent

Kafka 0.11.0.0 (Confluent 3.3.0) added support to manipulate offsets for a consumer group via cli kafka-consumer-groups command.

1. List the topics to which the group is subscribed

kafka-consumer-groups --bootstrap-server <kafkahost:port> --group <group_id> --describe

Note the values under "CURRENT-OFFSET" and "LOG-END-OFFSET". "CURRENT-OFFSET" is the offset where this consumer group is currently at in each of the partitions.

2. Reset the consumer offset for a topic (preview)

Explaining require and permit: params.require(:person).permit(:name, :age)

The params in a controller looks like a Hash, but it's actually an instance of ActionController::Parameters, which provides several methods such as require and permit.

The require method ensures that a specific parameter is present, and if it's not provided, the require method throws an error. It returns an instance of ActionController::Parameters for the key passed into require.

"How do I get started with Node?" is a commonly heard question in #Node.js. This gist is an attempt to compile some of the answers to that question. It's a perpetual work-in-progress.

And if this list didn't quite answer your questions, I'm available for tutoring and code review! A donation is also welcome :)

Setting expectations

Before you get started learning about JavaScript and Node.js, there's one very important article you need to read: Teach Yourself Programming in Ten Years.

Understand that it's going to take time to learn Node.js, just like it would take time to learn any other specialized topic - and that you're not going to learn effectively just by reading things, or following tutorials or courses. _Get out there and build things!

A Primer on Ruby Method Lookup

Method lookup is a simple affair in most languages without multiple inheritance. You start from the receiver and move up the ancestors chain until you locate the method. Because Ruby allows you to mix in modules and extend singleton classes at runtime, this is an entirely different affair.

I will not build contrived code to exemplify the more complicated aspects of Ruby method lookup, as this will only serve to confuse the matter.

When you pass a message to an object, here is how Ruby finds what method to call:

1. Look within singleton class
