phpMyAdmin is a web-based graphical administration interface for MySQL and MariaDB databases. It allows developers and DBAs to manage databases, tables, rows, users, and permissions through a browser without needing to use the command-line MySQL client. phpMyAdmin is especially useful for non-technical users who need to browse data, run queries, import/export CSV or SQL files, […]

Introduction Debian 13 Trixie is built around the ethos of stability and free software. Setting up configure nftables firewall rules on Trixie leverages the same proven Debian packaging system that powers millions of servers worldwide, while benefiting from the latest upstream releases included in the Trixie freeze. Follow each step carefully and the resulting configuration […]
Introduction Deploying install nginx on a Debian 13 Trixie machine is straightforward thanks to Debian’s policy-compliant packaging. Unlike rpm-based distributions, Debian stores configuration helpers in /etc/default/, uses update-rc.d for older init scripts, and provides dpkg-reconfigure for interactive package configuration. This tutorial stays on the systemd path throughout. Prerequisites Before you begin, ensure you have a […]
Introduction This guide explains how to Set Resource Limits with limits.conf on Debian 13 on Debian 13 Trixie. Debian Trixie uses systemd for service management, nftables as the underlying packet filter (with ufw or iptables front-ends still available), and AppArmor for mandatory access control. Every command is designed for a minimal Debian 13 install with […]
Redis (Remote Dictionary Server) is an in-memory data structure store used as a cache, session store, real-time leaderboard, pub/sub message broker, and rate-limiting backend. Redis stores all data in RAM with optional disk persistence, making it orders of magnitude faster than relational databases for lookups: sub-millisecond response times at millions of operations per second. Common […]
MongoDB is a document-oriented NoSQL database that stores data as BSON (Binary JSON) documents rather than rows in tables. This schema-flexible approach makes MongoDB ideal for applications with rapidly evolving data models, hierarchical data (product catalogs, user profiles, content management), geospatial queries, and high-volume write workloads. MongoDB 7.x introduced significant improvements including multi-document ACID transactions, […]
PostgreSQL (often called Postgres) is an advanced open-source relational database with a 35-year development history. Unlike MySQL/MariaDB, PostgreSQL prioritises SQL standards compliance, data integrity, and extensibility over speed-at-any-cost. PostgreSQL excels at complex queries, full-text search, JSONB document storage, geospatial data (PostGIS extension), and write-heavy workloads that require strong ACID compliance. It is the preferred database […]
