The ability to record and see everything happening across your web applications is essential when building resilient and highly available systems. All of your events—from application logs to errors to user behavior—contain data that could be useful to you and your team. When you have a central place to access all this information, finding issues and their root causes becomes easier because you have the data at your fingertips.

For many applications, access is usually through a single domain, such as yourapp.com. This way, the application developer is able to offer a unified experience to all users. This works great most of the time, but imagine a situation where you need to give each user a customized experience; how would you achieve this? One of the ways you can customize the user experience in a single application is by using account-based subdomains.

Have you ever found yourself rummaging through the fridge, trying to figure out what groceries you have and what you need to buy? Okay, maybe this isn't a super serious problem, but what better way to manage this chore than by building a web API? In this guide, we'll craft a grocery management API with Go and Gin.

When building your Laravel applications, you may sometimes need to use a NoSQL database to store and retrieve data. One popular choice is Amazon DynamoDB, a fully managed, serverless, and highly scalable NoSQL database service provided by Amazon Web Services (AWS). In this article, we'll take a brief look at DynamoDB. We'll then delve into how to use DynamoDB as a cache store in Laravel, and how to store Laravel models in DynamoDB using the baopham/laravel-dynamodb package.

Everything you do when using computers is related to files and folders. The browser you're using to view this webpage is a file on your device, and this webpage is a file on this website's server, which means everything is a file one way or another. In this article, you will learn everything you need to know to build files and folder-related features in your PHP applications.

If you are into programming, you might have used commands like cp, mv, cat, etc, to perform different operations using a text interface like bash or Windows PowerShell. This article discusses implementing command-line applications in Python with functionalities such as keyword arguments, flags, positional arguments, and mode selection. It also discusses how to implement the Linux head command in Python.

Hanami is a relatively new full-stack Ruby web framework. Unlike Rails, which has many default assumptions about how an app should be built, Hanami promises developer freedom by not imposing too many such defaults. The framework is also blazingly fast due to its low memory footprint and focus on minimalism. Combine that with a focus on strict abstractions, and you get a fully-featured Ruby framework that could rival Rails for building some applications, such as APIs and micro-services.

There are many ways to deploy a Ruby on Rails application to the internet. Between hosting on your own hardware, renting a virtual machine, using a cloud provider, and using a platform, the opportunities are endless. The low-hassle way to host a Rails application is to use a Platform as a Service (PaaS). In this article, we'll show you how to deploy a Rails Application to Render.com, and as a bonus, monitor it with Honeybadger! You can find the final project here on Github.

During my recent deep dive into new technologies, I found the classic issues of integrating numerous tech tools effectively. I've written about my experiences to save you the trouble I had. One essential component I've looked into is using Docker to implement containerization. While the initial setup takes a little longer, it significantly simplifies and optimizes your technological stack.
