MFC applications built with older Visual C++ versions often render with the classic Windows 95 appearance, ignoring modern system visual styles. This happens because the application isn’t explicitly linked to Common Controls v6.0, which provides visual styles support.

BBCode is a lightweight markup language commonly used in forums and legacy content systems. It’s simpler than HTML and more readable in raw form. While WordPress focuses on its block editor and native HTML support, you can add BBCode parsing if your content or users require it—though in most cases, modern alternatives are better choices….
HTML character encoding determines how characters are represented in your source code and rendered in browsers. UTF-8 is the standard, but understanding when and how to use character entities remains essential for reserved characters, symbols, and special cases. UTF-8: The Default Standard Modern HTML5 documents should always declare UTF-8 encoding: <!DOCTYPE html> <html lang=”en”> <head>…
The WordPress block editor (Gutenberg) and legacy visual editor can mangle custom HTML, delete formatting, and cause frustration for users who work directly with code. If you prefer writing HTML directly or need to preserve complex markup, you can disable the visual editing experience entirely. Disable for Your Own Account The simplest approach is to…
Displaying widgets selectively based on page context, user conditions, or post-specific rules is a common requirement in WordPress.

Several approaches let you adjust editor typography without touching core files. Using the Site Editor (Easiest) For block themes and WordPress 5.9+, the visual Site Editor is the simplest route: Navigate to Appearance…
HTTP 301 (Moved Permanently) redirects tell browsers and search engines that a resource has permanently moved to a new location. This preserves SEO value and prevents broken links when restructuring your site or changing domains. Basic Implementation The simplest approach uses PHP’s header() function with an explicit 301 status code: <?php header(“Location: https://www.systutorials.com/”, true, 301);…
WordPress generates excerpts by default using the first 55 words of post content. You can override this globally or per-post type by adding filters to your theme or a must-use plugin. Basic excerpt length filter Add this to wp-content/themes/your-theme/functions.php: function custom_excerpt_length( $length ) { return 35; } add_filter( ‘excerpt_length’, ‘custom_excerpt_length’ ); Replace 35 with your…
By default, WordPress displays full post content on index, category, tag, archive, and search pages. This duplicates content across multiple URLs, dilutes SEO value, slows page rendering, and forces readers to scroll through complete posts when they’re just scanning headlines. Using excerpts instead improves page load times, reduces crawl budget waste, consolidates ranking signals to…

The Emacs Wiki also maintains community-driven guides and examples. Emacs configuration Store your configuration in ~/.emacs.d/init.el rather than the legacy ~/.emacs file. This keeps your Emacs directory cleaner and…
Scala runs on the Java Virtual Machine, so you’ll need Java 11 or later installed first. Check your current version: java -version If you don’t have Java installed, install it through your distribution’s package manager or use a tool like SDKMAN. Installing via SDKMAN (Recommended) SDKMAN is the most reliable way to manage Scala and…
Xen remains in production use across cloud providers (AWS EC2, Citrix Hypervisor) and large infrastructure deployments, though KVM has become the default hypervisor for most Linux distributions. This guide covers installing a Fedora Domain-U on a Xen Dom0 using PXE boot, applicable to current Fedora releases. Prerequisites A working Xen Dom0 installation LVM backing store…
The startx command launches an X session without a display manager, reading configuration from $HOME/.xinitrc. By default, this file doesn’t exist—startx falls back to system defaults that typically only recognize GNOME or KDE. If you’ve installed MATE and want to use it with startx, you need to create a user-level configuration. Understanding startx Initialization When…

Fedora has evolved its hostname management over the years. Modern versions use systemd and the /etc/hostname file, while older releases relied on /etc/sysconfig/network. Here’s how to handle both scenarios. Using hostnamectl (Recommended) The most straightforward method on current Fedora is using hostnamectl, which handles hostname changes through systemd: sudo hostnamectl set-hostname newname.example.com For a hostname…
RPM Fusion provides software that the Fedora Project doesn’t ship—primarily due to licensing restrictions, patent concerns, or proprietary redistributability requirements. The repository splits into two branches: free: Open Source Software that Fedora cannot distribute due to other legal or policy reasons nonfree: Non-open source software, including proprietary drivers and restricted-use applications Enable both repositories on…
Thunderbird’s built-in compose window is functional but limited. Using Vim as an external editor gives you the full power of modal editing and your customizations for email composition. Prerequisites You need Thunderbird with the External Editor extension installed. As of 2026, this extension continues to work with current Thunderbird versions. Install it from the Thunderbird…
IPv6 is enabled by default on most Linux distributions. While IPv6adoption has grown, many environments still rely primarily on IPv4, and disabling IPv6 can simplify networking configurations or resolve compatibility issues. Quick Method: Disable via modprobe The most straightforward approach is to prevent the IPv6 kernel module from loading: echo “options ipv6 disable=1” >> /etc/modprobe.d/disable-ipv6.conf…
