Full-stack achievement system for SkillTree with backend (NestJS) and frontend (SvelteKit): - 26 achievements across 7 categories (XP, Skills, Levels, Activities, Streak, Branches, Special) - 5 rarity tiers (Common → Legendary) with distinct styling - Auto-unlock after XP gain, skill creation, and activity logging - Celebration animation on unlock with sparkle effects - Achievements page with category filters and progress tracking - IndexedDB offline support with local condition evaluation - Backend seeds achievements on startup, checks conditions after mutations - Stats overview extended with achievement counter - i18n translations (DE + EN) Also adds docs/MONETIZATION_REPORT.md with ranked analysis of all apps.

# tune-tcp.sh — Reduce TCP TIME_WAIT accumulation on macOS
|
|
#
|
|
# Problem: With 72+ Docker containers each running health checks,
|
|
# TIME_WAIT sockets accumulate and can exhaust ephemeral ports.
|
|
#
|
|
# macOS default MSL (Maximum Segment Lifetime) is 15000ms (15s),
|
|
# meaning TIME_WAIT lasts 30s (2x MSL). This script reduces MSL
|
|
# to 5000ms (5s), so TIME_WAIT drops to 10s.
|
|
#
|
|
# Usage:
|
|
# sudo ./tune-tcp.sh # Apply settings
|
|
# ./tune-tcp.sh --status # Check current values (no sudo needed)
|
|
#
|
|
# To run at boot, add to a launchd plist or call from startup.sh
|
