last - Enhanced Login History
The last module provides a highly flexible way to view system login history, supporting interactive exploration, tree-based grouping by reboot, and structured data exports (JSON/CSV).
When to Activate
- When the user wants to audit recent system login and logout activity.
- When checking system reboot history in a structured format.
- When performing interactive analysis of user sessions in a TTY.
- When exporting login records for security reporting or external analysis.
Core Principles & Rules
- Interactive Browsing: Default behavior in TTY is an interactive selector for records.
- Tree View: Use
--treeto group sessions by the reboot events that preceded them. - Structured Formats: Support for
-j(JSON) and-c(CSV) for easy parsing.
Patterns & Examples
Interactive Audit
# Browse all login/logout records interactively
x last
Reboot History
# Show only system reboot records
x last --reboot
JSON Export
# Get all login history as a JSON object
x last --json
Grouped View
# Display login records grouped by system reboots in a tree structure
x last --tree
Checklist
- Confirm if the user needs a specific format (JSON, CSV, Tree).
- Verify if filtering by user or reboot is required.

pufferlib
High-performance reinforcement learning framework optimized for speed and scale. Use when you need fast parallel training, vectorized environments, multi-agent systems, or integration with game environments (Atari, Procgen, NetHack). Achieves 2-10x speedups over standard implementations. For quick prototyping or standard algorithm implementations with extensive documentation, use stable-baselines3 instead.

fluidsim
Framework for computational fluid dynamics simulations using Python. Use when running fluid dynamics simulations including Navier-Stokes equations (2D/3D), shallow water equations, stratified flows, or when analyzing turbulence, vortex dynamics, or geophysical flows. Provides pseudospectral methods with FFT, HPC support, and comprehensive output analysis.
