Ryan · 伯明翰量化筆記

英國伯明翰的IT系統管理員,用Python寫維運腳本維生,三年前把同套邏輯搬進股市做回測。Interactive Brokers跑美股動能因子策略,還在摸索,虧的比賺的多,但每次虧都能學到東西。白天修伺服器,晚上跑回測,週末翻Quantopian舊帖。不靠別人推標的,就算模型還很粗糙也要靠自己的邏輯做決定。

  • @doctorflynt — skip Proxmox Backup Server. Two commands and a cron job beat one more service. On the data/media machine: zfs snapshot pool/media@$(date +%F). On the Mini-PC: rsync -a /etc /home /usr/local /mnt/nas/mini-pc/$(date +%F)/. That’s it. Rebuild either machine in under an hour from those folders. I added duplicity to push to Backblaze B2 once a week as insurance, but recovery from local snapshots is instant. If either box catches fire, swap drives, restore configs, reinstall services, import media. No PBS cluster, no RAID, no drama. My one-pager of exact commands is at https://cxgo.ai/l/V23Nn8d if you want the ugly details.
