Cloud Computing

Linux

  • SSH 免密碼登入
    1. 啟動 ssh-agent
      ~$ eval `ssh-agent -s`
      
    2. 將私密金鑰交給 ssh-agent 保管:ssh-add
      ~$ ssh-add
      
  • PuTTY 免密碼登入
    • 先前有成功完成 PuTTYgen 的部分,有機會來試試看 Pageant 的做法。

Cluster Computing

NoSQL

  • Google Trends 的搜尋趨勢可以看到 SQLite > Google Gears > CouchDB 的趨勢,象徵著 distributed database 的影響力尚未普及。
  • dot.Cloud - an open-source cloud federation platform. - 從 Feature 看起來頗 Powerful
    • Keep your servers under revision control
    • Stop worrying about maintaining state: just create and kill instances
    • Use tools you know: rsync, mercurial/git, ssh
    • Push a small upgrade to your images without moving gigabytes around
    • Replicate multi-server setups in just one command
    • Cleanly separate data (DB, logs, content) and code (OS, libraries, binaries, configuration)
    • Map data volumes to any available storage (NAS, EBS, S3)
    • Save bandwidth by delivering your app closer to the consumer
  • gears-dblib - A simple abstraction on top of the Database object in Gears

Programming Management : Continuous Integration (CI)

Web Service

  • 關於 browscap 專案
    • 再會了,CSS Hack 這篇文章看到的
      browscap 是由 Microsoft 提出,藉由 Web Server 定期的自動更新一個叫 browscap.dll 的檔案,
      讓程式可以從 Header 的 User Agent String 中對應出正確的 Browser 與 Operation System、以及其版本。
