一个哲学家的生活片段

Hacker News 上怎么说

  《哲学家生命历程片段》（Passages from the life of a Philosopher）读起来非常长见识。当年我们差一点就变成蒸汽朋克社会了！这里有用 Clojure[0] 和 Python[1] 实现的差分机（Difference Engine）。[0] https://gist.github.com/divs1210/6e388a31d4e0a425efe7…

  'Passages from the life of a Philosopher' was a very insightful read. We were this close to becoming a steampunk society! Here's the Difference Engine implemented in Clojure[0] and Pythton[1]. [0] https://gist.github.com/divs1210/6e388a31d4e0a425efe7…

  ……一开始只是个简单的计算装置，但他深入思考之后，单枪匹马搞出了图灵完备的设计，甚至还给它写了程序。• 看到高德纳（Knuth）对它的有趣引用（见 Russ Cox 的博客文章 https://research.swtch.com/tictactoe “Play Tic-Tac-Toe with…）后，我开始阅读巴贝奇的回忆录《哲学家生命历程片段》（Passages From the Life of a Philosopher，http://onlinebooks.library.upenn.edu/webbin/book/lookupid?ke...）。

  …started with a simple calculating device and, thinking about it more deeply, single-handedly came up with a Turing-complete design and was writing programs for it. • I started reading Babbage's memoirs "Passages From the Life of a Philosopher" (http://onlinebooks.library.upenn.edu/webbin/book/lookupid?ke...) after seeing an intriguing Knuth reference to it (see Russ Cox's blog post https://research.swtch.com/tictactoe "Play Tic-Tac-Toe with…

  ……一位上议院议员，另一位是下议院议员，提出了这个问题。我实在是无法理解，到底得混乱成什么样的思路才能问出这种问题来。——查尔斯·巴贝奇（Charles Babbage），《哲学家生命历程片段》（1864），第5章“第一号差分机”

  …of the Upper, and in the other a member of the Lower, House put this question. I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question. - Charles Babbage - Passages from the Life of a Philosopher (1864), ch. 5 "Difference Engine No. 1"

  ……‘往机器里输入错误的数据，能算出正确的结果吗？’……我实在是无法理解，到底得混乱成什么样的思路才能问出这种问题来。——巴贝奇（1864），《哲学家生命历程片段》，第5章“第一号差分机”。你总不能拿着一个专为 PSNR 优化的编码器，然后因为它的 SSIM 表现不好就“挑刺”吧，反之亦然。

  …you put into the machine wrong figures, will the right answers come out?" .... I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question. --Babbage (1864), Passages from the Life of a Philosopher, ch. 5 "Difference Engine No. 1" You can't reasonably use an encoder optimized for PSNR and then "ding" it for producing output with bad SSIM, or vice-versa.

  ……通常的历史，而且我不觉得这两个例子能证明“事实证明完全不是那么回事”：• 查尔斯·巴贝奇生于 1791 卒于 1871 年，在 80 岁生日前几个月去世。他在 1864 年写下了《哲学家生命历程片段》。• 舍茨（Scheutz）父子制造的瑞典差分机在这些回忆录里有被提及。在当时，它被看作是差分机的小型化/玩具/原型版本……

  …usual history and I don't think these two examples establish the "turns out to not be true at all": • Charles Babbage lived 1791–1871, dying a couple of months before his 80th birthday. He wrote his Passages from the Life of a Philosopher in 1864. • The Swedish difference engine, produced by Scheutz father and son, is mentioned in these memoirs. At the time, it was regarded as a smaller-scale/toy/prototype version of the Difference Engine…
