Code quality, clean code, refactoring, maintainability, and software engineering best practices.
This post covers .NET Core 2.1, which released in May 2018. Some of the predicted features below didn’t materialize as described; we’ll clarify what actually landed versus what was speculated. What is .NET Core? .NET Core is Microsoft’s open-source, cross-platform runtime for building applications in C#, F#, and Visual Basic. Unlike the monolithic .NET Framework…
Hibernate Envers is a proven auditing framework that automatically tracks changes to JPA entities without cluttering your domain model with logging code. It stores historical data in separate audit tables and lets you query entity states at any point in time. Why Use Hibernate Envers Envers handles the mechanics of change tracking transparently: Audits all…
Google’s search algorithms have become significantly more sophisticated. What passed for acceptable SEO a decade ago—keyword stuffing, aggressive link manipulation, deceptive tactics—now triggers manual penalties or algorithmic demotions. If you’re managing websites, understanding these mistakes can prevent serious ranking damage. Misusing nofollow Tags Many site owners incorrectly use rel=”nofollow” to hide pages from search results…
SEO is not quick. This is the reality that catches most people off guard. The internet has conditioned us to expect instant results — viral content, overnight success, algorithmic magic that transforms a website in weeks. None of that applies to SEO. Be direct about expectations: a newly published page typically needs 3-6 months to…
Call forwarding redirects incoming calls to another number when you’re unavailable or without coverage. It’s a carrier-level feature managed through iOS Settings, but actual support and behavior depend entirely on your carrier’s implementation. Enable call forwarding Open Settings → Phone Tap Call Forwarding Toggle the switch to On Enter the phone number where calls should…
Thunderbird’s adaptive junk filter can effectively reduce spam once configured and trained, but it doesn’t automatically move flagged messages by default. Here’s how to set it up properly. Enable automatic movement for incoming mail Access your account settings: Linux/Windows: Edit → Account Settings macOS: Thunderbird → Settings → Accounts Select your email account and click…
PowerPoint exports slides at 96 DPI by default, which is too low for professional printing. Print shops typically require 150 DPI for acceptable quality or 300 DPI for high-quality output. The UI export options in PowerPoint don’t reliably control the actual output DPI—you need to change a registry setting on Windows or use alternative methods…
Resource management and error handling are critical in systems programming. RAII (Resource Acquisition Is Initialization) originated in C++ and ties resource lifecycles to object scope, with destructors automatically cleaning up resources. C lacks destructors and exceptions, but you can achieve similar semantics using established patterns that are battle-tested in production systems. The goto-based cleanup pattern…
WordPress spam attacks come in three distinct categories: comment spam, user registration abuse, and brute-force login attempts. A layered defense using complementary plugins and server-level hardening handles all three effectively. Comment Spam Protection Akismet remains the industry standard for comment filtering. It ships with WordPress by default and uses machine learning trained on millions of…
MediaWiki stores its main page configuration in the MediaWiki:Mainpage system message. By default, this points to “Main Page”, but you can change it to any title that suits your wiki’s purpose. This process involves updating the system message, creating your new homepage, and handling redirects properly to avoid breaking external links and SEO. Step 1:…
Windows 7 reached end of support in January 2020. If you’re maintaining legacy Windows 7 Enterprise systems with Multiple Activation Keys (MAK), here’s how to handle activation for those remaining machines. MAK activation applies to Windows 7 Enterprise editions obtained through Microsoft Volume Licensing agreements. Each MAK has a limited number of allowed activations, so…
Printing PDF annotations with fidelity across different readers requires understanding each tool’s specific workflow. The fundamentals haven’t changed much, but modern versions offer more reliable options than they did years ago. Adobe Acrobat (Full Version) Acrobat provides the most control over annotation printing, but requires explicit configuration before print. Enable annotation printing in preferences: Open…
A failed BIOS flash can leave your HP Compaq laptop completely unresponsive — white screen, no boot, just LED blinking. Before declaring it dead, try HP’s built-in crisis recovery mechanism. This procedure has recovered many laptops that appeared permanently bricked. The process works even when CMOS corruption prevents normal startup. You’ll need a USB flash…
Thunderbird’s most powerful settings live outside the UI—buried in the config editor or preferences file. This guide covers setting emails to sort newest-first by default and enabling inline quoting for replies, two changes that significantly improve daily usability. Accessing the Config Editor Open the config editor at Edit → Preferences → Advanced → Config Editor,…
By default, closing the last tab in Firefox also closes the entire browser window. You can change this behavior through Firefox’s preferences so the browser stays open with an empty window. Access about:config Open Firefox and type about:config in the address bar. Firefox displays a warning about modifying preferences—this is expected and safe. Click “Accept…
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…
x86-64 (Intel 64, AMD64) is the dominant 64-bit instruction set architecture for consumer and enterprise computing. Whether you’re reverse-engineering binaries, writing performance-critical code, or understanding system internals, a solid grasp of x86-64 assembly is essential. Learning Foundations CMU’s Introduction to Computer Systems (15-213) course materials remain the gold standard for foundational machine-level programming. The accompanying…
Managing proxy settings through the GUI is tedious, especially when you need to switch between multiple proxy servers frequently. Rather than hunting through settings menus each time, command-line tools eliminate friction and enable scripted deployments across your infrastructure. The original SetProxy tool is outdated and incompatible with modern Windows versions. Use netsh or PowerShell instead—both…
Blocking window closure in MFC applications is necessary for critical operations, multi-step dialogs, and workflows that require user confirmation before exit. This requires handling both the close button and the Alt+F4 keyboard shortcut. Removing the Close Button from the System Menu The simplest approach is to remove SC_CLOSE from the system menu in your dialog’s…
Embedding child dialogs within a parent dialog is a practical technique for organizing complex MFC applications. This approach modularizes your UI by breaking it into logical, reusable components rather than cramming everything into a single dialog resource. Basic Implementation Create the child dialog as a WS_CHILD window and position it within the parent’s client area….
