API Design Principles: Building Interfaces That Last
Good API design: use resource-oriented URLs with nouns not verbs, apply HTTP methods properly like GET for read and POST for create, maintain consistency.
Welcome to the complete index of every article in our Programming Development collection on When Notes Fly. This page lists all 24 articles in the section, organized alphabetically for easy reference. Each piece is researched, written by hand, and grounded in academic sources, professional practice, or empirical data. Whether you are diving into Programming Development for the first time or returning to find a specific article, the index below gives you direct access to the full collection within Technology.
If you are new to Programming Development, we recommend starting with the foundational explainers and definitions before moving on to specific case studies, applied frameworks, and deeper analytical pieces. Articles are written for thoughtful readers who want substance over summary, with clear explanations of how ideas connect, where they come from, and why they matter. Use this index as a navigational map: skim the titles, read the short summaries, and click through to the pieces that draw your interest. Each article also links to related material so you can follow a thread of ideas across our entire Technology library.
Good API design: use resource-oriented URLs with nouns not verbs, apply HTTP methods properly like GET for read and POST for create, maintain consistency.
High-quality code: works correctly passing tests and handling edge cases, readable with clear naming and structure, maintainable allowing easy modifications.
Debugging techniques: reproduce consistently to isolate conditions, read error messages and stack traces, use systematic elimination.
Developer productivity isn't lines of code, hours worked, or features shipped. Real metrics: value delivered, code quality, problem-solving speed, impact.
Agile workflow: Sprint planning decides 1-2 week work, daily standup syncs progress and blockers, development happens, code review ensures quality, deploy.
Software development stages: understand requirements and define problems, plan architecture and tech stack, develop and test, then deploy.
Programming fundamentals universal across languages: Variables for named storage, data types like integers and strings, control flow, functions, loops.
Software architecture: high-level system structure showing how components organized, communicate, and divide responsibilities.
Technical debt: shortcuts or suboptimal solutions making future development harder. Like financial debt, borrow time now, pay interest later.
Software testing: unit tests check individual functions, integration tests verify components work together, end-to-end tests validate workflows.
Agile is an approach to building software that emphasizes iteration and collaboration over rigid planning. Learn what it is, how it works, and when it fails.
Blockchain explained without the hype: how distributed ledgers, hash functions, consensus mechanisms, and smart contracts actually work, and what problems they solve.
Code review is how software teams catch bugs, share knowledge, and maintain quality. Learn what Google's research found and how to give feedback that actually helps.
How cryptocurrency works: Bitcoin mining, wallets, halving, altcoins, DeFi, NFTs, stablecoins, real use cases vs speculation, and the regulatory landscape.
GraphQL is a query language for APIs that lets clients request exactly the data they need. Learn how it solves over-fetching and under-fetching, how it compares to REST, and when to use each.
A complete guide to computer networking: OSI model layers, TCP vs UDP, IP addressing, DNS, HTTP/HTTPS, CDNs, and how data travels from browser to server.
What is object-oriented programming? A clear explanation of classes, objects, and the four pillars: encapsulation, inheritance, polymorphism, and abstraction. OOP vs functional programming.
Platform economics explains how two-sided markets like Uber, Airbnb, and Amazon create value by connecting distinct user groups. Learn network effects, pricing, and when platforms fail.
REST APIs let web services communicate using HTTP methods and standard conventions. Learn Roy Fielding's constraints, HTTP verbs, status codes, and REST vs GraphQL.
Technical debt is the cost of choosing fast solutions over correct ones in software development. Learn its types, how it compounds, and strategies to manage it.
Version control systems like Git track every change to code, enabling collaboration, rollback, and reliable software development. Learn how Git works and why it matters.
An API (Application Programming Interface) lets software programs communicate. Learn how REST, GraphQL, and webhooks work, with real-world examples from Stripe to Google Maps.
The Agile Manifesto's 4 values and 12 principles defined modern software development. Learn what they mean, what the authors say went wrong, and what comes next.
Open source software allows anyone to view, modify, and distribute the code. Learn how GNU/Linux started the movement, how open source is funded, and why it now powers most of the internet.
