Show HN: Django-rclone: Database and media backups for Django, powered by rclone

Hacker News - Sat, 02/07/2026 - 6:33pm

django-rclone bridges Django's database layer with rclone's file transfer layer. You get native database dumps piped directly to any of rclone's 70+ supported cloud storage backends -- no temp files, no intermediate archives, no Python reimplementations of what rclone already does.

Show HN: AI agent forgets user preferences every session. This fixes it

Hacker News - Sat, 02/07/2026 - 6:29pm

I build AI agents for work and kept hitting the same issue: a user corrects the agent, the session ends, and the correction is gone. Next session, same correction. I tracked it across our users and the average preference gets re-corrected 4+ times before people just give up. Existing solutions don't really solve this. Memory layers store raw conversation logs. RAG retrieves documents. Neither extracts what the user actually wants as a structured, persistent preference. So I built pref0. It does one thing: extracts structured preferences from user corrections and compounds confidence across sessions. How it works in practice. Say you're building a customer support agent:

Session 1: User says "always escalate billing issues to a human, don't try to resolve them." pref0 extracts billing_issues: escalate_to_human, confidence 0.55.

Session 4: User flags a billing ticket the agent tried to auto-resolve. pref0 reinforces the preference. Confidence hits 0.85.

Session 7: A billing issue comes in. The agent routes it to a human without being told. No correction needed.

Now multiply that across hundreds of users. Each one teaching your agent slightly different things. pref0 maintains a structured profile per user (or team, or org) that your agent reads before every response.

The API is intentionally minimal. Two endpoints: POST /track: send conversation history after a session. pref0 extracts preferences automatically. GET /profiles/{user_id}: fetch learned preferences before the agent responds.

A few design decisions: > Explicit corrections ("don't do X") score higher than implied preferences. Stronger signal. > Preferences are hierarchical: user > team > org. New team members inherit org conventions on day one. > Confidence decays over time so stale preferences don't stick forever.

This isn't a replacement for memory. Memory stores what happened. pref0 learns what the user wants. You can run both side by side.

Works with LangChain, CrewAI, Vercel AI SDK, or raw API calls. Free tier available -> https://pref0.com/docs

Would love feedback on the approach, especially from anyone building agents with repeat users.

Show HN: Glance – Fast CSV inspection for the terminal (SIMD-accelerated)

Hacker News - Sat, 02/07/2026 - 6:20pm

I built this because I got tired of waiting for pandas to load just to peek at a CSV file. Glance handles multi-million row files in under a second with lazy parsing and SIMD optimizations.

Key features: - Instant schema inference (detects int64, float64, currency, dates, enums) - SQL-like filtering with numeric comparison support - Interactive pager (like less, but CSV-aware) with search - Auto-detects delimiters (comma, tab, pipe, semicolon) - Multiple output formats (table, CSV, TSV, JSON)

Performance on 5M rows (307 MB): - Display + schema: 0.09s (lazy parsing + SIMD line counting) - Full filter + sort: 0.88s

Technical bits: - mmap for zero-copy file access - Flat row storage (single vector with stride, no per-row allocations) - ARM NEON / x86 SSE2 for newline counting - memchr fast-path for quote-free lines, state machine fallback for RFC 4180 edge cases

Built in C++20 with comprehensive tests. Works on macOS and Linux.

It's valentine's week, so I built a chat app that you can acrually customize your crush and shoot your shot. ( Safely )
