Error Recovery Patterns
Design strategies for gracefully handling failures and restoring system functionality without data loss or user disruption.
2mo ago General intermediate
Bike-Shedding
Spending disproportionate time on trivial, visible decisions (tab vs space, variable naming) while complex, important decisions receive inadequate attention.
3mo ago General beginner
Code Freeze & Release Management
A period stopping new features entering a release branch — feature flags and continuous delivery eliminate the need for long freezes.
3mo ago General intermediate
Cognitive Load in Code Design
The mental effort required to understand code — good design minimises extraneous cognitive load so developers can focus on the problem, not the code structure.
3mo ago General intermediate
Database Seeding & Fixture Management PHP 5.0+
Populating databases with consistent, reproducible test and development data — using factories, seeders, and fixtures to create realistic scenarios without manual data entry.
3mo ago General intermediate
Dependency Audit & CVE Scanning PHP 5.0+
Automated scanning of project dependencies for known vulnerabilities (CVEs) — composer audit, npm audit, and tools like Snyk run in CI to catch vulnerable packages before deployment.
3mo ago General intermediate
Dependency Management Philosophy PHP 5.3+
Every dependency is a liability — prefer few well-maintained packages; pin versions via composer.lock; audit regularly.
3mo ago General intermediate
Feature Teams vs Component Teams
Feature teams own end-to-end delivery across the stack; component teams own a layer — feature teams ship faster but need platform support.
3mo ago General intermediate
Hofstadter's Law
"It always takes longer than you expect, even when you take Hofstadter's Law into account" — software estimation is systematically and recursively optimistic.
3mo ago General beginner
InnerSource
Open-source collaboration practices inside an organisation — any team can contribute to any internal repository, reducing silos.
3mo ago General intermediate
Pareto Principle in Engineering
The 80/20 rule — roughly 80% of effects come from 20% of causes. In engineering: 80% of bugs come from 20% of modules, 80% of performance gains from 20% of optimisations.
3mo ago General beginner
Polyglot Persistence 🧠 1
Using multiple different database technologies in a single application — each chosen for what it does best rather than forcing all data into one general-purpose store.
3mo ago General advanced
Runbooks & Playbooks 🧠 2
Documented step-by-step procedures for handling operational tasks and incidents — ensuring any on-call engineer can respond correctly under pressure without tribal knowledge.
3mo ago General beginner
Technical Roadmap Planning
Planning future technical investments framed as business outcomes — making technical work visible alongside product features.
3mo ago General intermediate
Diagram: ACID Properties ACID Properties PHP 5.0+ 🧠 2
The four guarantees of database transactions: Atomicity, Consistency, Isolation, and Durability.
3mo ago General intermediate
Diagram: Adapter Pattern Adapter Pattern PHP 5.0+
Converts the interface of a class into another interface clients expect, allowing incompatible interfaces to work together.
3mo ago General intermediate
Diagram: Allowlist vs Blocklist Allowlist vs Blocklist PHP 5.0+
Allowlists define what is permitted; blocklists define what is forbidden. Allowlists are always more secure.
3mo ago General beginner
Diagram: Architecture Decision Records (ADRs) Architecture Decision Records (ADRs)
Short documents capturing the context, decision, and rationale for significant architectural choices — creating an institutional memory of why the system is built the way it is.
3mo ago General beginner
Diagram: Attack Surface Attack Surface PHP 5.0+ 🧠 1
The sum of all points where an attacker can try to enter or extract data from a system.
3mo ago General intermediate
Blameless Culture
An organisational norm where incidents and mistakes are treated as systemic learning opportunities rather than individual failures deserving punishment.
