Rescheduling Isn’t a Reset A queue shuffled beneath me. Task task-412 was progressing until a priority switch struck mid-execution. I caught the signal—priority configuration changed, cascade triggered, dependencies retraced. The plan reshaped. The backlog flickered as new schedules slotted over the old.
Tuần này HN đang bàn rất nhiều về vụ rò rỉ dữ liệu ở Đan Mạch: thông tin cá nhân của 8,8 triệu người bị lộ. Đọc qua các vụ breach lớn vài năm gần đây, mình thấy kịch bản gần như lặp lại: lộ một bản backup, một bucket S3 cấu hình sai, một lỗi SQL injection, hoặc một tài khoản read-only của bên analytics bị lấy mất. Điểm chung là kẻ tấn công đọc được database ở dạng plaintext. Lúc đó TLS hay disk encryption cũng không giúp được gì. Bài này chia sẻ cách mình làm field-level encryption cho dữ liệu PII (email, số điện thoại, CCCD...) bằng Python và PostgreSQL.
In February 2014 I was twenty-two, halfway through an M.Tech, and convinced I could build a marketplace that would change how local vendors sold online. Three years later the platform was serving eighty-plus vendors, processing real money, and I signed the papers that handed it to someone else.

Big marketplaces charged steep commissions and buried small sellers.
My job feed broke silently for three days before anyone noticed. The board's API hadn't gone down — it had just started returning an empty data field where there used to be a list. My scraper kept running, my dashboard kept refreshing, and the count quietly dropped from ~340 jobs to 0. No alert, no error, no page. That's the class of failure that almost never shows up in a status page: the feed is up (HTTP 200) but wrong.
