Use magit-ediff to resolve merge conflicts

Use magit-ediff or 'e' on an unmerged item to resolve merge conflicts with ediff. Magit will set up an ediff with three buffers A, B and C. A and B are the original (conflicting) files, and C is the conflicted merge.

Use 'n'/'p' to move to the next/previous conflict, use 'a'/'b' to choose which changes (those in a A or B) should be the ones to keep in the merged file.

You can always just switch to buffer C and edit what the merged version should look like.

從 SocialCalc 到 EtherCalc

先前在《開源應用程式架構》一書中，我介紹了 SocialCalc 這個在瀏覽器中運行的試算表編輯器，以取代伺服器為中心的 WikiCalc 架構。SocialCalc 在瀏覽器中執行所有的運算，只有在載入和儲存試算表時才會使用伺服器。

追求效能是 Socialtext 團隊在 2006 年時設計 SocialCalc 的主要目的。重點在於：在 JavaScript 環境下執行客戶端運算，儘管在當年的速度僅有伺服器端 Perl 運算的十分之一，但仍然勝過 AJAX 來回傳輸資料造成的網路延遲：
