Programming languages (Python, JavaScript, C++, Go, Rust, Java) and their frameworks and libraries.
Static linking embeds all library code directly into your executable, eliminating runtime dependencies on shared libraries. This approach trades disk space for portability and eliminates “library not found” errors at runtime. Basic Static Compilation To statically link a simple C program, use the -static flag: gcc -static -o myprogram myprogram.c For C++: g++ -static -o…
To enable debugging, configure your CMake build with CMAKE_BUILD_TYPE set to Debug. This tells CMake to invoke the compiler with the -g flag, generating debug symbols that tools like gdb and lldb need. From your project’s root directory: cmake -DCMAKE_BUILD_TYPE=Debug -B build cd build make The -B build flag creates a separate build directory, which…
Google no longer displays author information in search results the way it did when Google+ existed. However, you can still control how your content appears in search results by using schema markup—specifically the author property in JSON-LD structured data. Current best practice: schema.org markup The modern approach uses JSON-LD structured data embedded in your page’s…
The HTML5 <canvas> element lets you draw graphics programmatically using JavaScript. Unlike static images or SVG, canvas renders raster (bitmap) graphics directly to a 2D or 3D surface, making it ideal for animations, games, real-time visualizations, and interactive graphics that need frequent updates. This guide covers canvas fundamentals and practical examples for sysadmins and developers…
Picking your first programming language matters, but it’s not the career-defining decision some make it out to be. What matters more is that you pick something reasonable and start building. That said, some choices will save you months of frustration. Know What You’re Optimizing For Before evaluating languages, answer these questions honestly: What do you…
Spring Shell is a framework for building command-line interfaces (CLIs) in Java applications. It provides structured command definition, argument parsing, tab completion, and history management—all integrated with the Spring ecosystem. Requirements and Setup Spring Shell 3.2+ requires Java 17+ and Spring Boot 3.2+. If you’re still on older versions, Spring Shell 2.x supports Java 8…
This guide covers building REST endpoints in ASP.NET MVC and consuming them from a frontend application. While this example uses AngularJS (end-of-life 2022), the backend patterns remain relevant for legacy system maintenance. For new projects, migrate to ASP.NET Core with modern frontend frameworks like React, Vue, or Angular. Database Setup Create the parts inventory table:…
AngularJS routing enables single-page applications by dynamically switching views based on URL patterns without full page reloads. Unlike server-side routing, AngularJS handles routing on the client, eliminating network round-trips and improving responsiveness—particularly useful when displaying different datasets based on route parameters. Install AngularJS and Dependencies Include AngularJS and the routing module. Using npm: npm install…
Quartz is an open-source Java library for scheduling background jobs and tasks. Whether you need to execute work at specific times, on recurring intervals, or in response to events, Quartz provides a robust scheduling framework that integrates with standalone applications, application servers, and clustered environments. Core Features Embeds directly into standalone or web applications Supports…
Parsing RSS feeds in PHP remains a common requirement for content aggregation. This guide covers practical patterns for fetching feeds, caching results, extracting content, and sanitizing output — with implementations that work reliably in production. Basic RSS Feed Parsing PHP’s SimpleXML extension provides a straightforward way to parse RSS feeds: <?php $feed_url = ‘https://example.com/feed.xml’; $feed…
Blocking JavaScript per-site in Chrome lets you stop intrusive scripts, malicious content, or resource-heavy trackers without disabling JavaScript globally. This gives you surgical control—some sites work fine without JS, while others need it. Access the JavaScript exceptions page Open Chrome and navigate to this URL in the address bar: chrome://settings/contentExceptions#javascript Alternatively, go through the menu:…
Displaying RSS feed items on a webpage is a practical way to aggregate external content. Here’s a production-ready approach using PHP’s SimpleXML to fetch, cache, and render feeds as HTML. Basic Implementation This function handles RSS parsing with built-in caching, error handling, and output escaping: <?php function output_rss_feed($feed_url, $item_count = 10, $show_description = true, $show_pubdate…
Self-hosting a photo gallery gives you control over your content. If you want to skip database management entirely, a handful of PHP solutions still work—though most are unmaintained. This post covers what’s still functional, where the limits are, and when you should choose something else instead. Static File-Based Gallery Scripts Single File PHP Gallery Status:…
cppreference.com is the authoritative resource for C++ language and standard library documentation. It covers all C++ standards from C++98 through C++26 with clear examples and cross-references. Bookmark it as your primary reference. The official C++ standard drafts are available through the C++ standards committee. While final standards require purchase, draft versions and proposals are freely…
Java eliminated pointers entirely in favor of automatic garbage collection. C++ gives you manual control through pointers and references, which provides performance benefits but introduces memory leak risks if misused. In Java, object references are automatically managed — you don’t allocate or free memory explicitly. The garbage collector runs periodically and reclaims unreachable objects. This…
GDB is the standard debugger for C/C++ development on Linux. This reference covers essential commands for breakpoints, execution control, inspection, and troubleshooting common debugging scenarios. Starting GDB gdb ./program gdb ./program core.dump # Debug with core file gdb -p <pid> # Attach to running process gdb –args ./program arg1 arg2 # Pass arguments to program…
Use std::filesystem for all new code. It’s exception-safe, cross-platform, and requires no external dependencies. #include <filesystem> #include <iostream> void ListAllFiles(const char *folderPath) { for (const auto& entry : std::filesystem::recursive_directory_iterator(folderPath)) { std::cout << entry.path() << std::endl; } } To filter by file type, check the entry status: void ListRegularFiles(const char *folderPath) { for (const auto& entry…
