Continuations

Posted on by

Basically, continuations let you put “time travel” into your code. This allows you to do things like run programs backward, sideways, or in other crazy ways.

Jesus’ money

Posted on by

.

The gospel of St. Matthew told of the angry Jesus driving the merchants and money-changers out of the temple, knocking over the tables of the money-changers and spilling their coins on the floor. Jesus was not opposed to capitalism and the profit motive, so long as economic activities were carried on outside the temple. In the parable of the talents, he praises the servant who used his master’s money to make a profitable investment, and condemns the servant who was too timid to invest. But he draws a clear line at the temple door. Inside the temple, the ground belongs to God and profit-making must stop.

自僱退休 1.3

真正可能會頹廢，漫無目的地生活的，是那些既不是打工，又不是自僱的人士。

（安：例如一些退休人士。如果我已經退休，又有足夠退休金的話，我基本上會積極墮落，瞬間頹廢。

那有沒有一個「防止腐敗系統」呢？）

「退休」本身是一個人為，而又違反自然定律的荒謬制度。「人類」並不是一種適合完全不工作的生物。「退休」就把人放在一個完全不工作的狀態，提高了人的衰退速度。「退休」根本是一個錯誤發明，你沒有必要跟這個制度而行。

（安：「人類」並不是一種適合完全不工作的生物。而根據 Paul Graham 的一篇文章所講，「人類」亦不是一種適合在大公司裡工作的生物。）

兩句可以結合，沒有衝突。

（安：那可以引申什麼呢？要麼就在細小公司工作，要麼就自己創造一些工作，即是自僱？那樣才符合自然定律，對人的身心健康，以致人際關係，都會是最好的？）

大公司的內部運作，就好像共產主義一樣。對於每一個員工來說，無論自己的工作質素幾好或者幾差，所得的金錢和精神回報，都會和其他大部分員工差不多。當一間機構不是論功行賞，甚至所謂的「功」很容易就給其他人奪去時，正常的員工即使原本是鬥志頑強，很快都會變成神志失常。

Internally most companies are run like Communist states. If you believe in free markets, why not turn your company into one?

Hypothesis: A company will be maximally profitable when each employee is paid in proportion to the wealth they generate.

Particles and Fields

Posted on by

To reveal it in advance, quantum field theory finally unified particles and fields. All particles became just quanta of fields. Some fields such as the Dirac field used to be known just as particles – electrons – while others were originally known as fields and not particles – such as photons that were appreciated later.
