This guide walks you through turning a fresh Rocky Linux 8 or AlmaLinux 8 machine into a self‑hosted file server that feels like your own cloud. It covers updating the system, adding EPEL, installing Apache, MariaDB and PHP, securing the database, creating Nextcloud’s database user, downloading and unpacking the latest tarball, configuring Apache with a virtual host and .htaccess support, and reloading the service. After launching the web installer you set up the data folder, link to MariaDB, pick an admin password, and then optionally secure everything with certbot‑generated HTTPS certificates while noting common pitfalls like mixing PHP handlers or misconfiguring Apache. With optional tuning for large media uploads, gzip compression, and timeouts, you finish the setup and can start adding users, quotas, and shared links, enjoying full control over your private cloud.

Nu Shell is a Rust‑powered, cross‑platform shell that turns command output into structured data, letting pipelines feel more like spreadsheets than plain text streams. On most distributions you can install it with the native package manager—for example `sudo apt install nu` on Ubuntu or Debian, `sudo dnf install nushell` on Fedora, or `yay -S nushell` on Arch; if a newer release is required, downloading and extracting the GitHub tarball to /usr/local/bin works as a fallback. Once launched with the simple command `nu`, you’ll see a familiar prompt that supports powerful built in commands such as `ls | where size > 1000000 | sort by -i size` to filter and order file lists, or `cat /etc/passwd | lines | each { $it.split(':')[0] }` which behaves like awk. You can further tailor the experience with aliases, a custom prompt, or auto‑completion scripts, but if your workflow relies heavily on traditional shell scripting you may need to wrap existing scripts with `bash -c` rather than converting them outright.

The article offers a practical how‑to for restoring sound on Ubuntu or Linux Mint when speakers go silent after an update. It guides readers through basic checks—unmuting the Master channel and confirming ALSA lists their audio card—before moving to more involved actions such as reloading kernel modules, resetting PulseAudio settings, and ensuring the user is in the audio group. The guide also suggests testing with a raw PCM stream to isolate PulseAudio issues, reinstalling key packages when corruption is suspected, and even tweaking blacklist entries or installing a newer kernel if all else fails. Overall it covers most common causes in just a handful of commands that can bring music back within minutes.

The guide walks you through installing Pritunl Enterprise VPN on Debian or Ubuntu using Docker, starting with updating the system and adding Docker to your user group. It pulls the latest Pritunl image, sets up a persistent data directory, runs the container exposing port 443 for both HTTPS management and VPN traffic, and waits until the internal PostgreSQL database is ready. After accessing the web UI you create a server profile—typically OpenVPN—and then generate client configuration files that can be loaded into any compatible Open‑VPN client. Finally, it suggests basic hardening steps such as limiting firewall access to port 443, enabling automatic updates, and using Docker’s restart policy to keep the service running after crashes.
