driftcurve vs UserFolderMigrator

driftcurve is an open-source household retirement planning engine for projecting finances and comparing retirement outcomes. It can model multiple household members, account types, debts, mortgages, pensions, Social Security and property sales. Its default Monte Carlo simulations resample annual market data from 1966–2024 across equities, Treasuries, residential real estate, inflation and Bitcoin. Users can adjust historical returns toward their own long-run targets or enter static annual assumptions. Risk-based spending guardrails solve for monthly spending and suggest adjustments based on portfolio thresholds and probability of success. A Compare page puts two scenarios on one chart. In default local mode, household data and saved scenarios stay in browser localStorage, while forecasts run through a Python backend; there is no account or server-side database persistence. Optional multi-user mode adds email/password accounts, server-side sessions, and stored profiles and scenarios. The project offers forecast and guardrails API endpoints, plus authentication, profile and scenario endpoints in multi-user mode. It is free under Apache License 2.0. The maker describes it as an educational modeling tool, not licensed financial, investment, tax or legal advice.

UserFolderMigrator is a free PowerShell script for Windows shell-folder moves, user-profile backup and restore, and folder redirection management. It can relocate Desktop, Documents, Downloads, Pictures, Music, and Videos, update their registry locations, and optionally remove the originals. Backups can include AppData, Wi-Fi profiles, printers, scheduled tasks, mapped drives, and WSL distributions. Restore proceeds through eight phases for files, registry, access controls, Wi-Fi, mapped drives, scheduled tasks, printers, and WSL distributions. MD5, SHA1, or SHA256 checksums are available, and checkpointing can resume interrupted operations. Dry-run simulates work without changing files or the registry; report-only mode creates HTML and JSON reports without changes. Notifications can go through SMTP, Microsoft Teams webhooks, or remote syslog. The script requires PowerShell 7 or later, Windows 10 or Server 2016 or later, and administrator privileges. The project says it is Windows-only and the main script has no GUI, though an interactive wrapper is included. It is provided under the MIT License.
