Since PHP 8, we’ve had attributes — a modern way to add metadata directly to classes, methods, or properties. Think of them like annotations in Java or decorators in Python. What are Attributes? Attributes let you “tag” parts of your code with extra information. Frameworks or libraries can then read these tags at runtime and act on them. Example: #[Route('/home', methods: ['GET'])] class HomeController { // ... } Here, the Route attribute describes how this controller should be exposed. ...

My Mac was almost full. It said that “Documents” used 39 GB, but I didn’t know what was taking so much space. As a software developer, I have tools like npm, Docker, and Homebrew that keep files to work faster. These files can get very big. Here’s how I fixed it. Step 1: Look at Documents I checked my Documents folder in Finder, but the files there were much smaller than 39 GB. Then I used Terminal: ...

In this tutorial, we created a Service Account with a Role and RoleBinding for read-only access to Pods. You can find the source code in the GitHub repository. What is a Service Account in Kubernetes? A Service Account in Kubernetes is a special type of account that is used by processes or applications running inside Pods to authenticate and interact with the Kubernetes API. Unlike User Accounts, which are typically associated with human users, Service Accounts are designed for non-human access. They are used to grant specific permissions to applications, allowing them to interact with the Kubernetes cluster in a controlled and secure way. ...

In this tutorial, we will set up Vault Agent to generate a .env file with secrets from HashiCorp Vault. We’ll use the AppRole authentication method to securely authenticate and retrieve secrets, then write them to an environment file for use in your application. You can find the complete configuration files and setup used in this tutorial in the GitHub repository. ⚠️ Important Note: This tutorial uses Vault in development mode (-dev) for simplicity. Development mode is not secure and should only be used for testing and learning purposes. In a production environment: ...

If you are confused about licenses like me, this guide helps you decide on licenses for software, documentation, and other practical works. Here, I’ll provide a simplified (but probably not entirely accurate) version of it. General Rule of Thumb: If you’re modifying an existing project, stick with its original license unless you have a really good reason to change it. If you do switch licenses, make sure it’s allowed and make it clear which parts use which license. For Software: ...

I have two runners in my project. One is on Microsoft Azure for Azure deployments, and the other is on DigitalOcean for its deployments. Today, I realized that all of my jobs are being handled by the Azure runner, causing our tests to take too much time due to significant network delay when connecting to the database across data centers. Therefore, I needed to configure specific jobs to run on designated runners. Here, I’ll explain how to do that. ...

I know it looks crazy, but to be honest, I am frustrated with searching “install docker ubuntu” and copying and pasting lots of commands every time. If this happens to you a lot, you can bookmark this gist and just copy and paste it to install Docker, Compose, and post-installation commands. for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; done && sudo apt-get update && sudo apt-get install ca-certificates curl gnupg && sudo install -m 0755 -d /etc/apt/keyrings && curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg && sudo chmod a+r /etc/apt/keyrings/docker.gpg && echo \ "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \ "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \ sudo tee /etc/apt/sources.list.d/docker.list > /dev/null sudo apt-get update && sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin && sudo groupadd docker && sudo usermod -aG docker $USER && newgrp docker && sudo docker run hello-world A shorter way If you don’t want to copy such a long command, you can easily run this one: ...

Kubernetes gives you the ability to deploy your app in a highly available way, and it has provisioning features that you can use to avoid manual tasks. There are tons of tutorials about Kubernetes out there, but in this simple post, I just want to give you the simplest deployment ever in Kubernetes. You will see how to deploy nginx with Kubernetes and access it easily. Before deployment, make sure you have properly installed kubectl and minikube, and remove any old stuff from minikube using the delete and start commands. ...

Finally, Laravel 10 is released. It requires PHP >= 8.1. Most of the features are added by the core Laravel team and not by other contributors, and it seems that there are no big changes compared to previous version releases. Let’s have a glance. New Type Hinting Model Nuno Maduro, creator of Pest, has added a new PHP style of type hinting and removed the old way of doc-block in all stubs and maybe the codebase. It seems that the change does not have a sensible difference for end-users :) ...

It is important to know about error types in PHP. With this knowledge, it would be easier to find and solve errors. Basically, we have 4 types of errors in PHP and I will show them to you with examples. 1. Notice PHP is not sure about whether it is an error or not! 2. Warning An error that is important and should be fixed but does not stop code execution. ...
