To understand a thing is to watch it near, then trace its edges from afar, and leave—silent, unseen. Only then, when time has passed, does it leave behind a tremor in the soul too soft to name.
Deploying modern web applications can be complex, especially when managing infrastructure. In this post, we’ll walk through how to deploy a Spring Boot application using Coolify, a self-hosted PaaS solution. We’ll use Docker Compose to containerize the app and Vultr as the hosting provider. This setup provides a lightweight, cost-effective, and developer-friendly deployment pipeline.
In distributed systems, generating unique identifiers is critical not only for ensuring data integrity but also for maintaining operational stability and batch processing efficiency. Traditional auto-increment keys are prone to collisions, while UUIDs can be problematic due to their size and performance impact.This post presents how a Snowflake-based ID generator was implemented in Java to address these issues effectively.
In event-driven systems, inconsistencies can occur between database state changes and event publication to a message broker. The transactional outbox pattern addresses this issue by storing both the data changes and the event payload within a single transaction, then reliably publishing the event afterward to ensure data consistency.
Designing databases for internationalization (i18n) and localization (l10n) is essential for global services. It involves more than handling translations, requiring careful attention to localized content, performance optimization, and scalable schema design. Common strategies include using separate tables, column expansion, JSON fields, and key-value stores, each with its own strengths and trade-offs.
Verifying the authenticity of your Git commits is essential, especially when working on open source projects or collaborating in a professional setting. GPG-signed commits add a layer of trust by ensuring that your commits are genuinely made by you. GitHub recognizes and displays verified badges for such commits, helping collaborators and users trust your contributions. This post explains how to generate a GPG key and configure your GitHub account to sign your commits automatically.
Effectively leveraging command-line tools can significantly boost developer productivity. Tools like Warp, Homebrew, Oh My Zsh, fzf, zoxide, Powerlevel10k, eza, bat, httpie, and ngrok help create a streamlined and efficient workflow, enabling developers to work more comfortably. By incorporating a variety of terminal CLI tools, you can build a more powerful and pleasant development environment.
