output: Numerical methods approximate solutions to differential equations through discretization. Euler's method is simplest but inaccurate. Runge-Kutta methods (RK4) offer better accuracy per step.


query: cross platform mobile development flutter

intent: building mobile apps with Flutter

output: lex

output: "Flutter" "cross-platform" mobile -butterfly -insect

output: lex

output: Flutter Dart widget "hot reload" -React -Native

output: vec

output: how to build cross-platform mobile apps using Flutter

output: hyde

output: Flutter uses Dart to build native-compiled apps for iOS and Android from a single codebase. Its widget system provides a rich UI toolkit with hot reload for fast development.


query: renewable energy solar panel efficiency

intent: evaluating solar energy

output: lex

output: "solar panel" efficiency renewable -space -satellite

output: lex

output: "photovoltaic" efficiency "solar cell" -solar -system

output: vec

output: how efficient are solar panels and what affects their performance

output: hyde

output: Modern solar panels achieve 20-25% efficiency for residential installations. Efficiency depends on cell technology, temperature, shading, angle, and panel degradation over time.


query: great barrier reef conservation

intent: protecting marine ecosystems

output: lex

output: "Great Barrier Reef" conservation protection -gaming -level

output: lex

output: "Great Barrier Reef" marine preservation -aquarium

output: vec

output: conservation efforts to protect the Great Barrier Reef

output: hyde

output: The Great Barrier Reef faces threats from coral bleaching, ocean acidification, and pollution. Conservation efforts include marine protected areas, water quality improvement, and coral restoration programs.


query: attention mechanism transformer architecture

intent: understanding transformer internals

output: lex

output: "attention mechanism" transformer architecture -ADHD -focus

output: lex

output: "self-attention" "multi-head" "query key value" -electrical

output: vec

output: how does the attention mechanism work in transformer architecture

output: hyde

output: Self-attention computes relevance scores between all pairs of tokens using query, key, and value projections. Multi-head attention runs multiple parallel attention functions for richer representations.


query: write ahead log database recovery

intent: understanding database durability

output: lex

output: "write-ahead log" WAL database recovery -diary -journal

output: lex

output: WAL "crash recovery" "transaction log" checkpoint

output: vec

output: how does write-ahead logging enable database crash recovery

output: hyde

output: Write-ahead logging writes changes to a log before modifying data pages. On crash, replay the WAL to restore committed transactions and undo incomplete ones, ensuring durability and consistency.

intent: exploring Tolkien's fictional world

output: lex

output: "Middle-earth" Tolkien geography map -real -actual

output: lex

output: "Lord of the Rings" Tolkien "Shire" "Mordor" map

output: vec

output: geography and map of Middle-earth from Tolkien's works

output: hyde

output: Middle-earth's geography spans from the Shire in the northwest to Mordor in the southeast. Key regions include Rohan's plains, Gondor's kingdom, Mirkwood forest, and the Misty Mountains.
