Accessible Tooltips
Tooltips that appear on hover, focus, and keyboard interaction, are associated with their trigger via aria-describedby, and can be dismissed without moving the pointer.

Atomic Groups
PHP 4.0+
Non-capturing groups written (?>...) that prevent backtracking once matched, locking in progress to avoid catastrophic slowdown.

Regex advanced
API Request Timeout Handling
1
Client-side deadlines, retries with backoff, and circuit breakers that keep your app responsive when an upstream API fails to reply in time.

API Design intermediate
AI Context Management
PHP 8.0+
The practice of selecting, ordering, and trimming what goes into an LLM's context window to maximise relevance while staying under token limits.

AI / ML intermediate
AI Fallback Routing
5
Automatically routing LLM requests to alternative models or providers when the primary fails, times out, or returns unusable output.

AI / ML intermediate
AI Model Selection Criteria
5
The systematic factors engineers weigh when choosing an LLM for a task: capability, cost, latency, context window, modality, hosting, and licensing.

AI / ML intermediate
AI Prompt Versioning
The practice of treating prompts as versioned artifacts — tracking changes, correlating outputs to prompt revisions, and enabling rollback when quality regresses.

AI / ML intermediate
AI Model Quantization
Compressing neural network weights and activations to lower-precision formats (int8, int4, fp8) to shrink memory and accelerate inference.

AI / ML advanced
AI Synthetic Data Generation
Using generative models to produce artificial training, testing, or augmentation data that mimics the statistical properties of real datasets without exposing originals.

AI / ML intermediate
async / await in JavaScript
ES2017
5
async functions always return a Promise; await pauses execution inside an async function until a Promise settles — giving asynchronous code the readability of synchronous code without blocking the event loop.

JavaScript intermediate
API Versioning
2
Strategies for evolving an API without breaking existing consumers — URI versioning, header versioning, and content negotiation.

API Design intermediate
AI Alignment
3
The research and engineering discipline of ensuring AI systems pursue goals that are consistent with human values, intentions, and safety — not just stated objectives.

AI / ML advanced
AI Context Poisoning
2
An adversarial technique where malicious instructions are injected into an LLM's context window — via user input, retrieved documents, or tool results — to hijack the model's behaviour.

AI / ML advanced
AI Governance
9
The policies, processes, and organisational structures that ensure AI systems are developed, deployed, and monitored responsibly — covering accountability, fairness, transparency, and compliance.

AI / ML advanced
AI Guardrails
4
Runtime constraints and safety filters applied around LLM calls to detect, block, or rewrite inputs and outputs that are harmful, off-topic, or policy-violating.

AI / ML intermediate
AI Observability
1
The practice of monitoring, tracing, and evaluating LLM-powered systems in production — covering latency, token costs, prompt drift, output quality, and failure modes.

AI / ML intermediate
Accessible Data Tables
HTML tables marked up with correct semantic elements and ARIA roles so screen readers can announce cell context — column header, row header, and position — to the user.

A* Pathfinding Algorithm
4
Heuristic search algorithm that finds the lowest-cost path using f(n)=g(n)+h(n), widely used in maps and game AI.

Abstract readonly Properties
PHP 8.4+
PHP 8.4 allows abstract readonly properties in abstract classes and interfaces — defining that implementations must provide a readonly property of a specific type.

PHP advanced
Actor Model
The Actor Model treats everything as an actor — isolated units that communicate only by message passing, never sharing state — eliminating race conditions by design.
