    • Next Step We live in a connected world, and modern software has to navigate this world. So the building blocks for tomorrow’s very largest solutions are connected and massively parallel. It’s not enough for code to be “STRONG and SILENT” any more. Code has to talk to code. Code has to be chatty, sociable, well- connected. Code has to run like the human brain, trillions of individual neurons firing off messages to each other, a massively parallel network with no central control, no single point of failure, yet able to solve immensely difficult problems. And it’s no accident that the future of code looks like the human brain, because the endpoint of every network are, at some level, human brains. From ZeroMQTuesday, December 04, 2012 52
    • Next Step 如何讓一個人可以維護上萬部機器 如何讓程式像人一樣的互相配合、互相合作 自我檢視、自我維護、自我協調、故障排除 故障預警 無中央集權式的管理Tuesday, December 04, 2012 53
    • 天下武功 熱情和視界才是重點 有熱 你以為你在創新, 其實是在代工 無堅不破 情但看不遠也沒有用 看 惟快不破 但沒有熱情持續努 力下去 也只會失敗 上班打卡制 你以為你在作 App,其 實你在做網頁 你以為 下班責任制 你在作雲端,其實你在 對於只有錘子的人, 作末端 你以為你在藍 海,其實你在紅海 他能解決的問題就是 從 Impossible 釘釘子 到 Im possible 理想勝過策略 不要隨便被新技術 和人 開放勝過封閉 們為新技術勾勒出的未來 簡單勝過複雜 吸引。相反,有時間的 話,要認真瞭解計算機的 公開勝過封鎖 歷史 Eat your own dog food!
