If you follow best practices then you’re tagging each of your Docker images with a unique tag or version whenever it gets updated. These tags might be the git commit hash, a CI/CD Build number or any other value that is usually generated automatically during your build process.

A very common, reoccurring thing that developers want to create is a feature that occurs over and over again on a certain schedule. This could be things like emailing out notifications at certain intervals, clearing some data from the database, deleting log files on the system or maybe just prepare data by conducting some heavy task in the middle of the night so it can be consumed in the morning by the users.

When you’re setting up a distributed system where there are multiple different applications and services that communicate with each other, you can choose to handle this communication in a few different ways.
One of the ways you can communicate between services while keeping them decoupled is by sending messages to Message Queues that other services pickup and execute. For example, imagine we have a web application that allow the user to upload videos. To optimize the delivery and performance of...

A Hash Table is one of the core data structures that you need to have a good understanding of as a Software Engineer. Unlike some other data structures that are rarely used in real life situations, Hash Tables are used all the time.

Storing your static or media files on a remote storage in the cloud such as Amazon Web Services S3 or DigitalOcean Spaces is one of the first things that I recommend you to do when you setup a new Django project that is ready to go into production.

You know that you’re working for an Enterprise business when you’re asked to integrate their website’s authentication with their Active Directory server. If you have no idea what Active Directory is, don’t worry it probably just means that you’re living within the StartUp bubble of web development!
Active Directory is Microsoft’s enterprise solution for storing user data. Many enterprises use it as a centralized location of all their employees data where they can easily update passwords, information and permissions from...

No matter what type of website your building these days, if you require some kind of authentication there is probably some kind of service or social network out there that would be a good fit for you and your application and that you could leverage for authentication and registration.
Are you building a gaming website? Why not authenticate with Blizzard’s Battle.net. Are you building an application with a technology target group? Maybe you can allow authentication with their GitHub account?...
