This guide covers practical font configuration using only free software and fonts available in standard repositories. Installing fonts Fedora ships with Liberation fonts, but ensuring you have version 2.x (which renders substantially better than 1.x) is the first step….
Thunderbird wraps lines at 72 characters by default—a sensible standard from the SMTP era, but one that can break formatting when sending code, logs, or plain text that needs to stay on single lines.

WordPress performance depends on three complementary caching layers: PHP bytecode caching (OPcache), page caching (WP Super Cache), and asset optimization (Autoptimize). Combined properly, they’ll cut your Time to First Byte in half and significantly improve Core Web Vitals. Enable OPcache in PHP OPcache caches compiled PHP bytecode in shared memory, eliminating parse and compile overhead…
Emacs startup is slow. If you’re using it for quick edits alongside other tools, waiting 2-3 seconds every time becomes friction. Heavy mode configurations, lazy loading chains, and initialization hooks add up fast. The server/client architecture solves this: start an Emacs server once, then spawn lightweight clients that connect almost instantly. Your first edit waits…

The proprietary fglrx driver reached end-of-life in 2015 and is incompatible with current Fedora releases. For modern AMD GPUs, use AMDGPU—AMD’s actively maintained open-source driver that supports Wayland, current kernel versions, and both desktop and compute workloads. GPU Compatibility RDNA and newer (RX 5000 series and later): AMDGPU is required and fully supported. GCN-era Radeons…

MediaWiki’s sidebar is managed through the MediaWiki:Sidebar special page, a simple text-based system that controls navigation for your entire wiki. Changes take effect immediately across all pages. Accessing the Sidebar Configuration Navigate to the sidebar editor using one of these methods: Direct URL (replace example.com with your domain): With pretty URLs: https://example.com/w/MediaWiki:Sidebar Without pretty URLs:…
MediaWiki’s default URL structure — www.example.com/w/index.php?title=TITLE — works functionally but creates poor SEO signals and awkward shareable links. Clean URLs like www.example.com/w/TITLE improve search visibility, readability, and user experience while making pages easier to reference. LocalSettings.php Configuration Open LocalSettings.php in your MediaWiki root directory and add these settings: $wgScript = “/w/index.php”; $wgArticlePath = “/w/$1”; The…

Here’s how to change this behavior and other useful tab management tips. Prevent Firefox from Closing: about:config Open a new tab and type about:config in the address bar Click…
Firefox’s extension ecosystem is mature enough that you should install conservatively. Each extension consumes memory, introduces potential compatibility issues, and creates another surface for security problems. The extensions listed here solve genuine problems; install only what you use. Ad Blocking uBlock Origin remains the standard. It uses significantly less memory than alternatives and supports complex…
Vim’s indentation system provides multiple approaches for formatting C/C++ code, from built-in operators to external formatters. The native tools work reliably for most tasks, while external formatters enforce stricter style rules when needed. The Indentation Operator and Text Objects The = operator re-indents text. It requires a motion or text object to specify what to…
cgdb is a curses-based frontend to gdb that keeps your source code visible while you debug. Unlike raw gdb, it splits the interface into two panes: source code on top, gdb command prompt below. If you’re already comfortable with Vim keybindings, cgdb feels natural—it uses the same navigation keys and modal editing paradigms you’re used…
Embedding child dialogs within a parent dialog is a practical technique for organizing complex MFC applications.
