Backward compatibility, 5

To enjoy the past without limiting your life progress, install the past as virtual machines in the present. 

— Me@2013-02-24 2:50 am

The attraction of virtualizing older operating systems is that it throws off the eternal yoke of backwards compatibility. Instead of bending over backwards to make sure you never break any old APIs, you can build new systems free of the contortions and compromises inherent in guaranteeing that new versions of the operating system never break old applications.

生疏荒廢

石頭永固 2 || use it or lose it || 不進則退 不用即棄

.

人的腦海之中,有一個「機會成本評價系統」,會自動刪除「沒有用」的才能,以節省記憶和時間資源。

「沒有用」既可以指「本身沒有用」,又可以指「本身有用 但不拿出來用」。對於「機會成本評價系統」而言,兩者沒有分別。

才幹以外,感情亦然。

Jailbreak

iOS jailbreaking is the process of removing the limitations imposed by Apple on devices running the iOS operating system through the use of hardware/software exploits – such devices include the iPhone, iPod touch, iPad, and second generation Apple TV. Jailbreaking allows iOS users to gain root access to the operating system, allowing them to download additional applications, extensions, and themes that are unavailable through the official Apple App Store.

在那一年

Memory 4.4 | Copy Me, 5.3 | Memento 4

這段改編自 2010 年 4 月 3 日的對話。

根據我的經驗,近乎只有一個情況,會令我真正明確回憶起,中學時代的某一件特定事件。那就是當收拾房間,整理一大堆物件的時候,偶然會見到那個時代的一些「紀念品」,例如 成績表、筆記、書籍、相片 和 電影戲票 等。

所以,為免遺失原本的自我,你應定期收集和保存「紀念品」,作為人生的「里程碑」。「紀念品」就好像是「記憶保險箱的鎖匙」,助你隨時喚醒多年前的詳細記憶,令你重遇年輕時的自己。你的信件、文章 和 作品,往往就是最佳的「紀念品」。

Memory

.

I have collected in this book memories extending over fifty years.

I am well aware that memory is unreliable.

It not only selects and rearranges that facts of our lives, but also embroiders and invents.

I have checked my version of facts wherever possible against other people’s memories and against written documents.

Memory 4.3

Copy Me, 5.2

這段改編自 2010 年 4 月 3 日的對話。

「十年前的我」和「現在的我」的記憶不盡相同,而導致不是「同一個人」,有兩重意思。

第一重是,「現在的我」(三十歲)比「十年前的我」(二十歲),多了十年的記憶。那就是我剛才所講的「增加」。

第二重是,即使只比較人生頭二十年的記憶,「三十歲的我」回憶(例如)「十六歲那年」發生了什麼事,已經不及「二十歲的我」回憶「十六歲那年」那麼詳細和準確。那就是我剛才所講的「變形、刪減 和 篡改」。

更震撼的是,如果我真的問你,「十六歲那年」發生了什麼事,你可以答到的,可能不出十件,甚至只有一兩件事。震撼的地方在於,「十六歲那年」共有 365 日,而你竟然只講到不夠十件事情。「十六歲那年」對於一個「三十歲的人」來說,只一堆模糊的印象,記憶的疑團。

根據我的經驗,近乎只有一個情況,會令我真正明確回憶起,中學時代的某一件特定事件。那就是當收拾房間,整理一大堆物件的時候,偶然會見到那個時代的一些「紀念品」,例如 成績表、筆記、書籍、相片 和 電影戲票 等。

怎樣才為之「同一個人」,或者「同一個自我」呢?

洛克(John Locke)的標準是,有同一個記憶,就為之同一個自我。

但是,即使是同一個人的記憶,又會隨時間 變形、增刪、篡改。如果用洛克的標準,我們平時所講「同一個人」之中的「同一」,只是幻覺。即使是「同一」個人,其實「自我」亦在不斷變化之中。例如,「十年前的我」和「現在的我」,並不是完全相同的「同一個人」。

Punishment

以直報怨 2

Punishment is for avoiding further harm, not revenge, unless revenge has such an effect.

If no further harm is possible, no punishment needed.

Memento 4

They were right. Lists are the only way out of this mess.

Here’s the truth: People, even regular people, are never just any one person with one set of attributes. It’s not that simple. We’re all at the mercy of the limbic system, clouds of electricity drifting through the brain. Every man is broken into twenty-four-hour fractions, and then again within those twenty-four hours. It’s a daily pantomime, one man yielding control to the next: a backstage crowded with old hacks clamoring for their turn in the spotlight. Every week, every day. The angry man hands the baton over to the sulking man, and in turn to the sex addict, the introvert, the conversationalist. Every man is a mob, a chain gang of idiots.

This is the tragedy of life. Because for a few minutes of every day, every man becomes a genius. Moments of clarity, insight, whatever you want to call them. The clouds part, the planets get in a neat little line, and everything becomes obvious. I should quit smoking, maybe, or here’s how I could make a fast million, or such and such is the key to eternal happiness. That’s the miserable truth. For a few moments, the secrets of the universe are opened to us. Life is a cheap parlor trick.

But then the genius, the savant, has to hand over the controls to the next guy down the pike, most likely the guy who just wants to eat potato chips, and insight and brilliance and salvation are all entrusted to a moron or a hedonist or a narcoleptic.

The only way out of this mess, of course, is to take steps to ensure that you control the idiots that you become. To take your chain gang, hand in hand, and lead them. The best way to do this is with a list.

統治機器

這段改編自 2010 年 3 月 27 日的對話。

我看了維基百科有關中國三十年代的文章。文章中說,1927 年至 1937 年間的那段時期,稱為「黃金十年」。那時,國民政府的「統治機器」,已經大致可以運作正常。

這裡「統治機器」的意思,其實就即是「作業系統(程式)」(operating system software)。表面上,「機器」是硬件。實際上,「機器」同時是軟件,而且軟件的「成份」多於硬件。試想想,當我們說「這裡有一部機器」時,並不是指「這裡有一堆金屬」,而是指「這裡有一堆金屬,以一個特別的方式來排列,繼而運作,有一個指定的用途。」

記住,「機器」是軟件。

星座運程

這段改編自 2010 年 3 月 20 日的對話。

星座對你性格的描述,通常也很「準確」。

一來,那些描述大部分情況下,都十分空泛。當你的說話越籠統,錯的機會就越微。

二來,每個人也有「多重自我」。當中總會有一個「自我」,符合「星座性格」的預測。例如,假設你的整體由自我 甲、乙、丙、丁、戊 組成。甲很外向,乙很內向。當「星座性格」預測你很內向時,甲沒有同感,所以不會出聲。但乙會很有共鳴,所以會「跳了出來」同意。整體的效果,就好像星座準確預測你的性格。

「性格心理測驗」會可靠很多,但都有類似的現象,所以不能盡信。
