觀我者誰 2.4

Posted on by

這段改編自 2010 年 3 月 20 日的對話。

假設你的整體由五重「自我」組成：甲、乙、丙、丁、戊。那樣，你並不是只有五個「自我」，因為「甲乙」可以組合成一個「自我」；「甲、丙、戊」又可以組合成另一個「自我」；如此類推。

有如「變形金剛」中，幾隻小機械人既可以獨立存在，又可以合體成一隻大機械人。所以，「自我」其實比一般人所想像的，豐富很多倍。

Zawinski’s law of software envelopment

Posted on by

Zawinski’s Law of Software Envelopment relates the pressure of popularity to the phenomenon of software bloat:

Every program attempts to expand until it can read mail. Those programs which cannot so expand are replaced by ones which can.

Examples of the law in action include Emacs, MATLAB, Mozilla and Opera.

其他優點不是不可以講。你可以在之後順帶一提。而你的每一個額外優點，一定要講到和作一個「電腦程式編寫員」直接相關。

如果你想說自己「數學頭腦上乘」，你就講：「我的數學成績不俗，反映心思細密。寫程式時，應該不會有什麼抽象難題，令我想不通。」

如果你想說自己「體壇明日之星」，你就講：「我的體育成績不俗，反映體格優良。寫程式時，即使間中需要趕工，連續十多小時工作，我的身體都會應付自如。」

如果你想說自己「文筆扣人心弦」，你就講：「我的寫作成績不俗，反映思路清晰。寫程式時，即使要我負責編寫文件或者說明書，我都可以妥善完成。」

Plan 9

Posted on by

Plan 9 failed simply because it fell short of being a compelling enough improvement on Unix to displace its ancestor. Compared to Plan 9, Unix creaks and clanks and has obvious rust spots, but it gets the job done well enough to hold its position. There is a lesson here for ambitious system architects: the most dangerous enemy of a better solution is an existing codebase that is just good enough.

我發覺在不同學生面前，我會顯現成不同的人。雖然我都會化身成「老師」的身份，但會是不同版本的「老師」。即使是講同一個課題，面對不同學生，我自然會以不同方式 和 不同程度 去表達，而毋須任何刻意。所以，我對「多重自我」現象的感覺，十分強烈。

Games for Change

Posted on by

Games for Change (also known as G4C) is a movement and community of practice dedicated to using digital games for social change. An individual game may also be referred to as a “game for change” if it is produced by this community or shares its ideals.

The Games for Change Festival

Since 2004, Games for Change has hosted the Games for Change Festival in New York. Often referred to as “the Sundance of Video Games”, the Games for Change Annual Festival is the biggest gaming event in New York City. It brings together leaders from government, corporations, philanthropy, civil society, media, academia, and the gaming industry to explore the increasing real-world impact of digital games as an agent for social change.

如果是求職應徵時推介「自己」，第一個訊息應該是：你可以怎樣為公司賺錢？

而第二個訊息則應該是：在「為公司賺錢」這一方面，你有什麼過人之處？為什麼要聘請的應該是你，而不是你的競爭者？

例如，假設你應徵「電腦程式編寫員」的工作。你應該用以下類型的答案：

我寫程式的造詣很深，所以可以高效率地，為公司編寫到高質素的程式。

（那很空泛。有沒有證據？）

我在大學主修電腦，成績是全學系的頭三甲。

（本公司的應徵者的成績都會很高。有沒有具體一點的東西？）

我在學時多次參加「程式編寫設計」比賽，其中有五次都入圍最後三強。這是我的部分程式作品，請看看，試一試使用。

（好。你的程式都算是方便易用。對於這個面試，你有沒有補充？）

我對貴公司和貴公司的範疇有一點深入研究，發覺貴公司的產品發展方向，出現了一點問題 ……

但不用擔心，以下是解決方案 ……

如果你同意我這個方案，貴公司可以考慮，聘請我去執行它。

Analytic continuation, 4

Posted on by

In complex analysis, a branch of mathematics, analytic continuation is a technique to extend the domain of a given analytic function. Analytic continuation often succeeds in defining further values of a function, for example in a new region where an infinite series representation in terms of which it is initially defined becomes divergent.

Life is boring

A young person is as bored as an old person.

A young person’s life seems to be interesting

because he can imagine how interesting his life will be.

在不同人的面前，你會顯現成不同的人，即使你沒有任何虛偽造作。

在不同人的面前，你會自然顯現成不同的人。

「好人」的意思是，你在他面前，你最好的一面會自動顯現出來。

Civilization II

Posted on by

In June 2012, a Reddit user named Lycerius posted details of his decade long Civilization II game, since dubbed “The Eternal War”. This garnered a great deal of interest from users of the site and the story quickly went viral, spreading across the web to many well known blogs and news sites. The game, which had been played since 2002, closely mimicked the regime found in the novel Nineteen Eighty-Four, with three superpowers all engaged in multiple-front warfare.

— Wikipedia on Civilization II

I’ve been playing the same game of Civ II for 10 years. Though long outdated, I grew fascinated with this particular game because by the time Civ III was released, I was already well into the distant future. I then thought that it might be interesting to see just how far into the future I could get and see what the ramifications would be. Naturally I play other games and have a life, but I often return to this game when I’m not doing anything and carry on. The results are as follows.

  • The world is a hellish nightmare of suffering and devastation.
  • There are 3 remaining super nations in the year 3991 A.D, each competing for the scant resources left on the planet after dozens of nuclear wars have rendered vast swaths of the world uninhabitable wastelands.

這段改編自 2010 年 6 月 2 日的對話。

如果是推介「智能手機」，你第一個要帶出的訊息就應該是：「智能手機」的主要功用是什麼？「智能手機」比起一般的手提電話，有什麼額外功能？為什麼我需要購買一部「智能手機」，而不是一般的手提電話？

而第二個訊息則應該是：如果我要買「智能手機」，有很多牌子可以選擇，為什麼我要跟你買？你公司的「智能手機」，比起其他智能手機，有什麼過人之處？

例如，「智能手機」除了是一個手提電話外，其實亦是一部「掌上電腦」。一般電腦所做到的事情，例如收發電郵、上網 和 修改文件 等，「智能手機」都可以做到。

（有些一般手提電話，都可以收發電郵。）

「智能手機」的螢幕大很多，而且還有虛擬鍵盤。「一般手機」的螢幕極小，而且只能以數字鍵當作鍵盤，打字十分不便。還有，因為「智能手機」是「掌上電腦」，有成千上萬的「應用程式」和「遊戲程式」可供選擇。

（你這一款「智能手機」，無論是功能還是價錢，都和其他牌子的相若。）

無錯。但是，其他牌子一般只有一年或兩年的保養。而我介紹的這一部，卻有長達三年的保養期。還有，修理手機期間，本公司會借出一部同一型號的手機給你，以盡量減低你的不便。

The Dragon Book, 2

Posted on by

Most people don’t realize that writing a compiler like this is only about 2 months work for one talented person who read the Dragon book. Since the compiler only has one body of code to compile, it is much easier to write. It doesn’t have to be a general-purpose compiler. It doesn’t have a math library, for example.

And we have the ability to add any feature to the language that we want easily… this is the same power Paul Graham talks about in On Lisp, the power to invent new language features that suit your exact application domain. Lisp does this through a mechanism called macros.
