Python OOP Day 3: Inheritance, Polymorphism, and Duck Typing Explained

·1 views

A tutorial series on Python object-oriented programming has reached its third installment, focusing on inheritance and polymorphism. The guide explains three types of inheritance — single, multilevel, and multiple — showing how child classes can reuse and extend parent class behavior. It also covers method overriding and the built-in super() function, which allows child classes to call parent methods without duplicating code. Polymorphism and duck typing are demonstrated through a practical payroll system where different employee types respond to the same method call in their own way. The article includes working code examples and diagrams to illustrate how these concepts apply in real-world Python projects.

Beginner SEO Diary: How to Build a Keyword List Using Only Free Tools

A blogger documenting their SEO learning journey shares the process they followed on Day 4 to build their first keyword list using free tools like Google Keyword Planner, AnswerThePublic, and Search Console. Industry data suggests long-tail phrases of three or more words account for roughly 92% of all searches and convert at more than double the rate of short, generic terms. The writer emphasizes that matching a keyword to search intent is more important than chasing high search volume, noting that a mismatch between content format and what Google already ranks can prevent a page from ranking regardless of writing quality. They recommend manually reviewing actual search results for each shortlisted keyword, a step they describe as the most useful filter that many beginner guides overlook. Volume figures from free tools, particularly Google Keyword Planner, are advised to be treated as rough estimates rather than precise guarantees.

How One Developer Built a Home Server from an Old Laptop for Free

A developer set up a home server using an old, unused laptop to explore low-cost ways for students to host software projects without paying for cloud services. Inspired by a conversation with a friend, he installed Ubuntu Server LTS on the laptop after wiping Windows and creating a bootable USB drive. The setup required no graphical interface, relying entirely on terminal commands for configuration and package installation. With the server running, he decided to self-host his personal website and experiment with a media server. The project took an unexpected turn when he discovered Docker and containers, opening up a broader range of possibilities.

How to Fix Common Code Splitting Mistakes and Boost Web App Performance

Code splitting is a widely used technique that breaks large JavaScript bundles into smaller, on-demand chunks to improve initial load times, but improper implementation can slow applications down rather than speed them up. Common pitfalls include over-splitting, which generates too many small chunks and increases network request overhead, and under-splitting, where chunks remain too large to deliver real performance gains. Developers also face issues with incorrect splitting points that create waterfall loading delays, as well as shared module duplication that inflates total download size across multiple chunks. Large third-party libraries can further undermine splitting efforts by bloating otherwise targeted chunks. Identifying these problems requires careful analysis of bundle structure and performance metrics before applying targeted fixes.

How CQRS Pattern Fixed a Construction App's Weekly Crash Under Peak Load

A field workforce reporting platform repeatedly crashed every Friday at 4:30 PM when thousands of construction workers simultaneously submitted weekly logs, overwhelming the database with concurrent read and write requests. Engineers redesigned the system using Command Query Responsibility Segregation (CQRS), routing write requests through Azure Service Bus so background workers could process submissions at a steady pace rather than all at once. The change eliminated end-of-week downtime by spreading a five-minute traffic spike across a manageable fifteen-minute processing window. However, the shift to asynchronous processing introduced eventual consistency, causing project managers to see outdated dashboards and prompting frustrated workers to resubmit forms multiple times, generating duplicate records. The team addressed this by adding unique submission IDs to prevent duplicates and displaying a processing status indicator in the UI so users understood their data was being handled.
