The guide walks you through adding Oracle’s MySQL 8.0 repository to Ubuntu, downloading the configuration package, installing it with dpkg, and then running an apt update so that the newest binaries become available. Once mysql‑server is installed it asks for a root password and immediately runs a secure installation script that removes anonymous accounts, blocks remote root logins, deletes test databases, and reloads privilege tables. You can confirm the server’s health by checking its status with systemctl, connecting to the MySQL shell, and running a simple SELECT version() query; this gives you an instant sanity check. Finally, the article reminds you to keep your packages up‑to‑date, back up regularly, and points out common troubleshooting steps such as inspecting journal logs if the service fails to start.

On Ubuntu 22.10, 22.04 or 20.04 this guide shows how to install the Rust compiler and Cargo with just a few commands, starting by updating the system so you avoid glibc‑related build crashes. While the Ubuntu repository offers a precompiled binary for quick testing, it recommends rustup because that tool keeps your compiler, Cargo and standard library in sync across updates. After installing, you can verify everything works by running rustc --version and cargo --version, then creating a simple hello_world project to confirm Cargo is functional before dealing with common pitfalls such as leftover Ubuntu‑repo binaries that clash with rustup paths. If you need the latest language features, the article explains how to switch to nightly builds but cautions that they may be unstable for production use.
