用 GitHub Actions 做的監控服務 Upptime
是在 Twitter 上看到這個：

然後翻到 Upptime 這個 open source monitoring 工具，直接是用 GitHub Actions 提供的 schedule (cron job) 每五分鐘跑一次。這邊要注意的是，如果是 public repository 的話不受限制，如果是 private repository 的話會有機會把 quota 吃完：
Billing note: Upptime uses thousands of build minutes every month (approximately 3,000 minutes in the default setting). If you use a public repository, GitHub offers unlimited free build minutes, but if you use a private repository, you'll have to pay for this time.
依照說明是用 GitHub Actions、GitHub Issues、GitHub Pages 三個功能在運作：
- GitHub Actions is used as an uptime monitor
- GitHub Issues are used for incident reports
- GitHub Pages are used for the status website
除了用這三個功能外，另外還是會每天塞一些資料回 git history 裡面：
We also record the response time once per day and commit it to git history. This way, we can graph long-term trends in your websites' response times by going through git commit history. We generate these graphs once every day, also using schedulers.
好像可以玩看看...

用 GitHub + Netlify + Cloudflare 管理靜態網站...
最近 GitHub Pages 支援 HTTPS (透過 Let's Encrypt，參考「GitHub 透過 Let's Encrypt 提供自訂網域的 HTTPS 服務」這篇)，但測了一下不是我想要的效果，就找了一下網路上的資源，結果有找到還算可以的方案... 先把網站放在 GitHub 上。(不需要設定 GitHub Pages) 然後用 Netlify 變成網站並且開啟 HTTPS。(可以選擇使用系統內提供的 Let's Encrypt，會透過 http-01 認證。如果因為 DNS 還沒生效的話也沒關係，可以之後再開。) 然後用 Cloudflare 管理 DNS 的部份 (主要是因為他的 root domain 可以設 CNAME，一般會提到的 ALIAS 就是指這個)。 這樣整個靜態服務都不用自己管理，而且有蠻多 header 可以設定，其中與 GitHub Pages 最主要的差異是 Netlify 支援 301/302…

GitHub 放出了他們整理過的 GitHub Advisory Database
GitHub 宣佈開放他們整理過的 GitHub Advisory Database：「GitHub Advisory Database now open to community contributions」，Hacker News 上有 GitHub 的 PM 回答一些問題，也可以看看：「GitHub’s database of security advisories is now open source (github.blog)」。 對應的 repository 在「github/advisory-database」這邊可以看到，用的格式是 Open Source Vulnerability format，裡面都是 JSON 檔案。 裡面看起來是從 2017/10 開始的資料，這樣算起來大約累積了四年半，算是一個來源...
