AWS Lambda is a serverless computing service that allows you to run code in response to events without provisioning or managing servers. Integrating Jenkins with AWS Lambda can help automate workflows, such as deploying code, triggering serverless applications, or running scheduled tasks.
Docker has changed the way developers build, ship, and run applications through the use of containers. One powerful feature that Docker provides is multi-stage builds. Multi-stage builds allow developers to create optimized Docker images by using multiple FROM statements within a single Dockerfile.
In this post, we’ll deep-dive into the configuration of the LAMP and LEMP stacks, covering how to install, configure, and integrate Apache/Nginx with MySQL/MariaDB and PHP. By the end, you'll have a fully functioning web server on Ubuntu, capable of handling PHP-based websites and dynamic content.
In our previous posts, we’ve explored the fundamental concepts of Git Bisect and how to effectively use it for debugging by identifying the commit that introduced a bug. One of the most powerful features of Git Bisect is its ability to automate the testing process using scripts or testing.
Automate Shadow of the Tomb Raider benchmarks on Ubuntu using a lightweight Bash framework. Run repeatable tests across resolutions, quality presets, and Proton or native builds while automatically collecting and organizing JSON performance results.
I thought automating game benchmarks on Linux would take a few days. Two working scripts later, I was convinced the hard part was done. Then I tried adding more games… and spent the next few weeks discovering just how creative game developers can be when it comes to breaking automation.
Amazon S3 is a highly scalable, secure, and durable object storage service provided by AWS. It stores files such as application artifacts, backups, media, etc. Automating file uploads to S3 can be integrated with AWS S3 to automate file uploads.
Integration testing is a critical phase in the software development that ensures different components of an application work together as expected. Running integration tests in Dockes offers several advantages, such as consistency, isolation of dependencies, and ease of setup.
If you’re looking to set up a web server on Ubuntu, you're in the right place! This post will guide you through the process of setting up a web server using the LAMP (Linux, Apache, MySQL, PHP) and LEMP (Linux, Nginx, MySQL, PHP) stacks.
Debugging complex codebases can be one of the most challenging tasks in software development, especially when you're trying to pinpoint exactly where a bug was introduced. Git Bisect is an essential tool that simplifies this task by using a binary search algorithm to identify the problematic commit.
