Good collaboration in open source projects

Video recording: https://www.youtube.com/watch?v=E5_tL62mUbc

Over the years, I've started thinking that participating in the open source community is like traveling on a path, toward becoming not only better programmers, but also becoming better people by working together.

You might think of it as a path toward enlightenment, growing ourselves as human beings. So what follows is really my personal philosophy which I'd like to share with you.

The first thing is this: The most important part of every open source project is the people. While code is important, the center is always the people.

開源之道

Original transcript: http://allisonrandal.com/2012/04/15/open-source-enlightenment/

這幾年來，我慢慢覺得，我們參與開源社群，就像是在一條道路上並肩而行：這不僅讓我們成為更好的程式設計者，也讓我們通過與人合作，而成為更好的人。

您可以將它想成一條修行之道，讓身而為人的我們能夠不斷成長。接下來，我想談談我對開源世界的個人觀點，希望能與您分享。

首先，人是一切開源專案的核心。程式碼是很重要，但最核心的永遠是人。

      resulttype = "t"
      result = value.value + "test"
      scf.PushOperand(operand, resulttype, result)
  ), 1]

From SocialCalc to EtherCalc

Previously, in The Architecture of Open Source Applications, I described SocialCalc, an in-browser spreadsheet system that replaced the server-centric WikiCalc architecture. SocialCalc performs all of its computations in the browser; it uses the server only for loading and saving spreadsheets.

For the Socialtext team, performance was the primary goal behind SocialCalc's design in 2006. The key observation was this: Client-side computation in JavaScript, while an order of magnitude slower than server-side computation in Perl, was still much faster than the network latency incurred during AJAX roundtrips:

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：
