# Push-ups

Being able to do more push-ups doesn’t mean that you can endure more pain. Instead, it means you have stronger muscles so that you can feel less pain for the original number of push-ups.

# 善利用愚蠢 1.2

Stupidity is like nuclear power; it can be used for good or evil.

（安：那樣，即是愚蠢的人當中，有一部分你無論多麼用心教導，也不會變成賢智的人。那怎麼辦？）

（安：但是，有些情況下，無可避免要和「不智人士」相處。那又怎麼辦呢？）

Now, the common paradigm is that the teacher-student ratio is critical — fewer students means higher-quality teaching. But if you turn your students into teachers, you gain leverage. You move the fulcrum over.

# Pay it forward

The expression “pay it forward” is used to describe the concept of asking that a good turn be repaid by having it done to others instead.

The concept was rediscovered and described by Benjamin Franklin, in a letter to Benjamin Webb dated April 22, 1784:

I do not pretend to give such a Sum; I only lend it to you. When you […] meet with another honest Man in similar Distress, you must pay me by lending this Sum to him; enjoining him to discharge the Debt by a like operation, when he shall be able, and shall meet with another opportunity. I hope it may thus go thro’ many hands, before it meets with a Knave that will stop its Progress. This is a trick of mine for doing a deal of good with a little money.

Ralph Waldo Emerson, in his 1841 essay Compensation, wrote: “In the order of nature we cannot render benefits to those from whom we receive them, or only seldom. But the benefit we receive must be rendered again, line for line, deed for deed, cent for cent, to somebody.”

In 1916, Lily Hardy Hammond wrote, “You don’t pay love back; you pay it forward.”

# Copyleft 6

Copyleft: Richard Stallman wrote the goal “no software copyright” in terms of the language of the existing software copyright system.

That’s why I say that “copyleft” is a virtual machine.

# Copyleft 5.3

「Free」這個英文字有兩個可能的意思。一個是指「自由」；另一個是指「免費」。在 GNU Project 開始時，Richard Stallman 還沒有分清楚這兩個意思。後來，他再三強調，「Free Software」的意思是指「自由軟件」，不是指「免費軟件」。「自由軟件」是否「免費」，並不是他直接關心的事情。他指出，程式員都可以靠售賣「自由軟件」為生。重點是，不應限制買家如何利用、修改 和 複製 買回來的程式。

# Copyleft 5.2

（安：「Copyleft」的原意是，令到電腦程式免費？）

Richard Stallman 覺得電腦程式應該給人互相複製。「電腦程式」的本質就是「極容易複製」，因為「複製程式」的成本近乎是零。Richard Stallman 覺得，既然是這樣，我們就不單不應該阻止電腦程式用家複製程式，而且還應該鼓勵，以推動人類電腦知識的傳播和發展。

# Free Software

GNU GPLv3 Logo

“Free software” does not mean “noncommercial.” A free program must be available for commercial use, commercial development, and commercial distribution. Commercial development of free software is no longer unusual; such free commercial software is very important. You may have paid money to get copies of free software, or you may have obtained copies at no charge. But regardless of how you got your copies, you always have the freedom to copy and change the software, even to sell copies.

Resistance to the organized mass can be effected only by the man
who is as well organized in his individuality as the mass itself.
–- Carl Jung

The reasonable man adapts himself to the world;
the unreasonable one persists in trying to adapt the world to himself.
Therefore all progress depends on the unreasonable man.
— George Bernard Shaw

（安：但是，”改變世界” 意思並不明確。所以，這個講法很空泛。）

“他最大的影響是為自由軟件運動豎立道德政治法律框架。他被許多人譽為當今自由軟件的鬥士、偉大的理想主義者，但同時也有人批評他過於固執、觀點落伍。” — 理查·斯托曼, 維基百科

Copyleft

Copyleft是一由自由軟件運動所發展的概念，是一種利用現有著作權體制來挑戰該體制的授權方式，在自由軟件授權方式中增加copyleft條款之後，該自由軟件除了允許使用者自由使用、散佈、改作之外，copyleft條款更要求使用者改作後的衍生作品必須要以同等的授權方式釋出以回饋社群。

Copyleft授權方式雖然與常見的著作權授權模式不同，選擇 copyleft授權方式並不代表作者放棄著作權，反而是貫徹始終，強制被授權者使用同樣授權發佈衍生作品。Copyleft授權條款不反對著作權的基本體制，卻是透過利用著作權法來進一步地促進創作自由。

Copyleft type licenses are a novel use of existing copyright law to ensure a work remains freely available.

If you want to accomplish something in the world, idealism is not enough — you need to choose a method that works to achieve the goal. In other words, you need to be pragmatic.

# Job: Security

Our only real economic security lies in
our power to meet human needs.

So the worse conditions become,
the more evident human needs become.

Our security does not lie in our organizations or our jobs;
disruptive technologies may simply make them irrelevant.
