Cloud Backup & Disaster Recovery
1
Automated backups with tested restores, defined RPO/RTO targets, and cross-region replication for catastrophic failure recovery.

Test Parallelization Gotchas
Hidden runtime hazards when tests execute concurrently — shared state, race conditions, and resource contention turn green suites red intermittently.

testing intermediate
Cloud Region Selection
1
The decision of which cloud region(s) to deploy workloads into, balancing user latency, data residency law, cost, and service availability.

AI Fallback Routing
4
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
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 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.

Memory Pressure Detection
PHP 7.0+
Proactively identifying when a PHP process approaches its memory limit so corrective action can be taken before a fatal error.

Database Query Result Streaming
PHP 8.0+
2
Processing large result sets row-by-row without loading the entire dataset into memory - essential for PHP CLI scripts handling millions of rows.

Error Recovery Patterns
Design strategies for gracefully handling failures and restoring system functionality without data loss or user disruption.

NoSQL Injection
PHP 5.4+
2
Attacker-controlled input embedded into NoSQL queries (MongoDB, Redis, Couchbase) that subverts query intent — bypassing auth, exfiltrating data, or executing server-side code.

8.8
Prompt Caching
API feature where a static prompt prefix (system instructions, large context) is cached server-side, dramatically reducing cost and latency on repeated calls that share the prefix.

Reasoning Models & Test-Time Compute
A class of LLMs trained to allocate extra inference-time compute to internal reasoning before answering, achieving large gains on math, code, and logic at the cost of latency and tokens.

ai_ml intermediate
Server-Side Includes (SSI) Injection
Attacker-controlled SSI directives (`<!--#exec ... -->`) injected into pages parsed by Apache or another SSI-enabled server, achieving file disclosure or remote command execution.

Internal Developer Platform (IDP)
A curated, self-service layer on top of cloud and CI/CD infrastructure that product teams use to ship services without filing tickets — paved roads that make the right thing the easy thing.

Load Balancer Types — L4 vs L7
Layer-4 load balancers forward raw TCP/UDP packets based on IP and port; layer-7 load balancers terminate HTTP and route based on paths, headers and cookies — different trade-offs for different traffic.

Shadow DOM
A browser feature that attaches a scoped, encapsulated DOM subtree to an element — styles and IDs inside the shadow tree do not leak in or out, enabling true component isolation on the web.

Software Composition Analysis (SCA)
The practice and tooling for identifying all open-source and third-party components in a codebase, detecting known vulnerabilities (CVEs) in them, and flagging licence risks — distinct from static analysis of your own code.

Discriminated Unions
2.0 A union of types that each carry a shared literal field (the discriminant) allowing TypeScript to narrow exhaustively — the canonical way to model mutually exclusive states.

typescript intermediate
Type Guards & Narrowing
2.0 Type guards are expressions that narrow a union type to a more specific type at runtime — telling TypeScript exactly which branch of a union you're in.
