Apollo and Daphne is a story from ancient Greek mythology, retold by
Hellenistic and Roman authors in the form of an amorous vignette;
The curse of Apollo, the god of the sun and music, was brought onto him when
he insulted the young Eros (a.k.a. Cupid) for playing with bow and arrows.
Apollo was a great warrior and said to him, "What have you to do with
warlike weapons, saucy boy? Leave them for hands worthy of them. Behold the
conquest I have won by means of them over the vast serp... 阅读全帖 |

My heart is in my hands
My head is in the clouds
My feet have left the ground
My life is turning around and round
And every voice inside my head is telling me to run like mad
Oh bows and arrows stars and sunsets

Every heartbeat, every kiss just
Makes me wonder what all this is

With the war bows he has shot around 250 yards with arrows of 800 grains and
around 225 yards with arrows of 1,545 grains. This would suggest that
distances of 200 yards and more were achievable by our archers with
seriously heavy projectiles. |

向晚意不适，驱车登古原, 正是当时的心境。车到山顶，俯瞰全城——这是一座中世纪就

音乐是有魔力的，这毋庸置疑。这首曲子，从车里的收音机里缓缓放出，让我一下把视

因为我在KDE上task-bar也是auto-hide，在windows上task-bar也是auto-hide。
Remmina全屏的时候，鼠标走到桌面最下方首先唤起的是KDE的task-bar。
而这个task-bar有被Remmina全屏遮住在下面，所以什么都看不到。
我试验把KDE的task-bar改成always visible，这样就可以唤起windows的taskbar了。
这里的原因是：Remmina不截获KDE的鼠标或键盘事件。
比如这个鼠标唤起task-bar的事件，既是KDE的事件，也是windows的事件，
Remmina不截获它，把它传给KDE了，结果windows的task-bar就不能唤起。
如果KDE的task-bar设为always visible，那么这个事件就不是KDE事件了，
这个事件就被Remmina传给windows，唤起了windows的taskbar.
Ctrl+Alt+Arrow在Remmina时好用也是一个道理。
另外Alt+Tab，这个组合既是KDE也是windows切换程序的事件，
Remmina不截获它，所以它... 阅读全帖 |

发帖数: 1136 | 24 monad的却有不对称的问题, 但是那是由它的数学结构决定的,Haskell也没办法哦.
其实monad早就不是唯一的选择,譬如写parser,monad的限制就太强了. Alternatives有
functor/applicative functor/arrow/iterable这类的啊. 而且applicative functor
应该是对称的. 现在的parser很多用arrow, 比如hxt(xml parser).
关于do block:
haskell官方wiki里面是不鼓励大家滥用do block的, 的却, do block很多情况可以
被>>=代替.
但我个人觉得完全不是问题啊! Haskell所有东西是immutable的,也就是说referential
transparency在do block里面也能保证, 那这玩意就算再像imperative些(其实骨子里
还是FP),再丑陋些, 也不会影响逻辑或者程序的正确性吧.
换句话说,如果c语言没有指针,所以变量都是immutable,那c也是FP.

大牛这内涵太多得看半年。
你这个type constructor的说法很好。
type本身的定义也是lambda的一部分。typed lambda就是靠一堆运算定义出已知type。
type constructor本身就是arrow。可以把type看成是lambda的某种语法糖把。
这样的话探讨一下，function本身也是静态compile time决定的，和type constructor
一致。而runtime function apply to value和create data from constructor是等价
的。特别是如果考虑type就是lambda的语法糖的话。
只要运算基于已知type，type level programming可以完备。但type本身不是基本定义
。感觉讨论FP/OOP应该还是可以放弃type只用arrow和object。
很同意OO和category不能完全直接对比。只能类比。

盛洪
写罢“什么是文明”，就拿起话筒对张宇燕说，这篇文章写得我“心惊肉跳的”。这是
我不曾有过的的心理感觉。也许，这不仅是因为这篇文章的逻辑所导致的结论是令人悲
观和恐怖的，而且与我过去一般接受的有关历史和世界的基本观念框架有着根本的分歧
，尽管近年来我已经对这一框架产生了怀疑，但将这种怀疑变成文字，仍会引发意想不
到的震撼。例如，我们一般认为，“现代”比“传统”好；中国文化，尤其是民国前的
中国文化是传统的，而西方文化则是现代的;西方文化是一般的、世界性的，其它文化
则是特殊的、民族的；“现代化”给人们带来了越来越多的福利；西方人则把现代化带
来给了全世界，不管他们是如何带来的；等等。我相信，除了我以外，大多数三、四十
岁的、与我有着相近的有关历史和世界的知识结构的人，都会持有这种看法。然而，当
我试图用经济学去剖析历史时，问题出现了。
经济学可谓西学的一种，有趣的是，用这种西学却很容易发现西方文化的倾向性。她并
