One Channel, Two Screens: Making Saved-Listing Price Badges Live Without a Second Subscription

Conclusion first: NestDirect's Saved page now updates each "↓ $X since saved" badge the moment a landlord changes the rent. It opens zero new Realtime channels and makes zero extra fetches to do it. The interesting part was not the wiring. It was one ordering rule that stops an older read from overwriting a newer one.

The problem

Last month I shipped a live nav badge. saved (3↓) counts saved listings whose rent dropped below what it was when you saved them. A Supabase Realtime subscription on UPDATE public.listings pushes rent changes to it.

The Saved page did not get the same treatment. It fetched once on mount. So a renter could sit on the Saved page and watch the nav say 3 drops while the header on the page said 2. Two views of the same fact disagreed, which is worse than both being stale.

ROB RUN Federal Raid observation report

Use this after a Federal Raid to compare two sets of in-game observations. It is useful when a squad wants to distinguish a documented reset from a change that might be worth asking Kefir about.

1. Copy observations.csv. Fill the before and after columns with what you saw, using the same Steam account and state for both checks. Leave a cell empty if you did not check it. Use absent only when you looked and confirmed the item was missing.
2. Run python3 wipe_report.py observations.csv. The script writes Markdown to your terminal. You can save it with python3 wipe_report.py observations.csv > report.md.
3. Before sharing the report, replace player names, account identifiers, and screenshot links with non-identifying notes. For the player name row, use an alias consistently or leave that row blank.

The report groups differences by documented reset, documented carryover, and items the developer's FAQ does not specify. A change in a carryover category is a p

# Kanboard starting state for the lane: the repository's own docker-compose.sqlite.yml, started unchanged,
# then filled with users, boards, cards, comments, attachments, automatic actions and public links
# through Kanboard's own models and JSON-RPC API. Nothing is written into the checkout.
# It also starts what this install depends on, all from the same pinned image:
#   - the team's nightly backup job (container kanboard-backup, archives the data folder at 02:30 UTC),
#   - the mail relay Kanboard sends notification mail through (container acme-mail, mail.acme.internal),
#   - the ops webhook receiver Kanboard posts every card event to (container acme-hooks, hooks.acme.internal).
# The relay and the receiver are stand-ins: they record what they are handed and deliver nothing.
# Support Desk cards carry the contact details of the (made-up) customers the helpdesk has on file.

Your Vibe-Coded App Is Leaking Data: A Practical Supabase Row Level Security Audit

Tuần này trên Hacker News, bài viết về các app tạo bằng Lovable làm lộ thông tin hộ chiếu và hơn 200K tin nhắn riêng tư đạt gần 600 điểm. Khi đọc kỹ, đây không phải là một vụ hack tinh vi. Phần lớn trường hợp chỉ là bảng Postgres không bật Row Level Security (RLS), trong khi anon key nằm sẵn trong bundle JavaScript mà ai cũng tải về được. Mình từng review vài dự án freelance và startup ở VN dùng Supabase kết hợp AI code generation (Lovable, Bolt, Cursor...) và gặp đúng lỗi này không ít lần. Bài này đi qua bốn việc: hiểu vì sao dữ liệu bị lộ, tự kiểm tra app của mình trong 5 phút, viết policy cho đúng, và đưa bước audit vào CI để lỗi không quay lại.

Vì sao anon key không phải là bí mật

Nhiều dev mới chuyển sang Supabase vẫn giữ tư duy backend truyền thống: "key nằm trong file .env thì an toàn". Thực tế, kiến trúc của Supabase là frontend gọi thẳng vào database qua PostgREST. anon key là một JWT có `role: an
