Compiling LaTeX documents with BibTeX involves multiple passes—typically three runs of latex followed by one bibtex run to resolve citations. This sequence is identical across most documents, making it perfect for automation with a Makefile. Basic Makefile Template Here’s a practical Makefile for LaTeX with BibTeX support: FILENAME = main LATEX = pdflatex BIBTEX =…
On Fedora/RHEL-based systems: dnf install ecryptfs-utils On Debian/Ubuntu: apt-get install ecryptfs-utils Load the kernel module modprobe ecryptfs To ensure the module loads automatically on boot, add it to /etc/modules-load.d/: echo “ecryptfs” | sudo tee /etc/modules-load.d/ecryptfs.conf Create directories You’ll need two directories: one for encrypted storage (.private) and one as the mount point (private). The .private…
Xen remains a production hypervisor for enterprise deployments (AWS EC2, Citrix Hypervisor), though KVM has become the default for most Linux distributions. If you’re deploying Xen in 2026, you’ll likely be working with recent stable releases rather than the legacy versions covered in older guides. This guide covers building a modern Xen Dom0 environment on…
The rpm and dnf commands let you inspect exactly which files a package installed and find the package that owns a specific file. These queries work on both the host system and inside containers like Toolbox or Distrobox. List Files from an Installed Package rpm -ql package-name This recursively lists all files and directories the…
Firefox performance on Linux can be significantly improved through configuration tuning. Most of these settings apply across platforms, though this guide focuses on Linux-specific considerations. Network Pipelining HTTP pipelining allows Firefox to send multiple requests on a single connection before waiting for responses. Modern HTTP/2 and HTTP/3 handle multiplexing more efficiently, but pipelining can still…
The mailx (or s-nail on modern distributions) command remains useful for scripted email delivery, particularly when you need to send alerts or notifications automatically. Gmail’s SMTP service works well for this, though it requires TLS authentication and specific configuration. Prerequisites Most Linux distributions include mailx or s-nail by default. On systems using s-nail (Ubuntu 20.04+,…
A Linux box serving as a network gateway needs two network interfaces: eth0: Connected to the local network (LAN) with IP 192.168.0.1 eth1: Connected to the upstream network (Internet) with IP 198.51.100.1 The goal is to allow clients on the 192.168.0.0/16 network to route traffic through this gateway to reach external networks. Enable IP Forwarding…
A SOCKS5 proxy tunneled through SSH provides encrypted communication between your client and a remote server. This is useful for bypassing network restrictions, securing connections on untrusted networks, or routing traffic through a trusted server. Basic Setup The simplest approach uses SSH’s dynamic port forwarding with the -D flag: ssh -D 8080 username@sshd_server This creates…
Keeping Thunderbird running constantly makes sense for monitoring incoming mail, but leaving it on the taskbar consumes screen real estate. System tray integration is cleaner—minimize to a small icon and optionally display unread message counts. Thunderbird’s addon ecosystem provides platform-specific solutions for this. Note that addon availability and compatibility can vary; check the Mozilla Addons…
Installing NVIDIA drivers on Fedora is straightforward when using RPM Fusion repositories. This guide covers modern Fedora releases (39+) using DNF package management. Prerequisites Before starting, determine which driver your GPU requires. Check the NVIDIA driver download page or use this command to identify your GPU: lspci | grep -i nvidia For newer GPUs (Maxwell…
ISO images are sector-by-sector copies of optical media stored as binary files. They’re useful for archiving DVDs or creating portable copies without keeping physical disks around. On Linux, several tools can accomplish this—dd is the simplest, but modern alternatives offer better features. Using dd to Create an ISO Image The most straightforward approach uses dd:…
Compiz Fusion is a lightweight 3D window manager and compositing system that can replace your standard window manager. While it’s rarely the default choice on modern Fedora installations, it remains available for users who want its visual effects and functionality. Note: Compiz development has slowed significantly. Most Fedora users today use Wayland-based desktops (GNOME, KDE…
The default number of loop devices on most Linux systems is 8, which is often insufficient for scenarios like running multiple virtual machines with loop device-backed storage, containerized environments, or disk image management. If you need more than the default allocation, you’ll need to increase max_loop. First, check your current loop device count: losetup -f…
Xen remains a robust hypervisor for production environments—AWS EC2, Citrix Hypervisor, and many hosting providers still rely on it. However, KVM has become the default for most Linux distributions due to simpler management and better integration with standard tooling. For new deployments on standard Linux, evaluate KVM with libvirt or container solutions like Docker and…
Customizing your desktop environment to match macOS aesthetics remains popular on Linux, though the approach differs significantly from GNOME 2 era configurations. Modern desktop environments like GNOME (40+) and KDE Plasma (5/6) use different theming systems, but achieving an Apple-inspired look is still straightforward. Current Desktop Environment Options GNOME 40+ uses CSS-based theming and GTK…
Converting audio tracks from video files is useful for extracting soundtracks, creating audio-only versions for podcasts, or generating files optimized for audio playback. While MPlayer was historically used for this task, ffmpeg is now the standard tool—it’s actively maintained, more efficient, and handles both extraction and encoding in one step. Installation Install ffmpeg on your…
Modern GNOME uses dconf as its configuration backend, replacing the older GConf system. Whether you’re managing a single workstation or deploying across multiple systems, understanding dconf and gsettings is essential for customizing GNOME environments efficiently. Understanding the Configuration Stack GNOME’s configuration hierarchy works like this: dconf — the low-level database storing all settings gsettings —…
After running on MediaWiki, we migrated back to WordPress. Both platforms have their strengths, but WordPress proved to be the better fit for our site’s goals. What WordPress Does Better for This Site Plugin Ecosystem and Content Discovery WordPress’s plugin landscape is significantly deeper than MediaWiki’s. The YARPP (Yet Another Related Posts) plugin and its…
Crontab controls what runs and when. Each crontab entry has this format: .—————- minute (0-59) | .————- hour (0-23) | | .———- day of month (1-31) | | | .——- month (1-12) OR jan,feb,mar,apr … | | | | .—- day of week (0-6) (Sunday=0 or 7) OR sun,mon,tue … | | | | |…
Andrew Fikes, Principal Engineer at Google, presented on storage architecture and the fundamental challenges that emerge when operating at scale. The presentation from the 2010 Faculty Summit remains relevant for understanding how distributed storage systems must be designed and the trade-offs inherent in large-scale deployments. Core Storage Challenges at Scale Google’s storage systems had to…
