Even though we recognize that we are inexcusably greedy, we still want to have it all. About two and a half years ago, we set out to create the language of our greed. It’s not complete, but it’s time for a 1.0 release — the language we’ve created is called Julia. It already delivers on 90% of our ungracious demands, and now it needs the ungracious demands of others to shape it further. So, if you are also a greedy, unreasonable, demanding programmer, we want you to give it a try.

if files have not changed, Git doesn’t store the file again—just a link to the previous identical file it has already stored.

Git thinks of its data more like a set of snapshots of a mini filesystem. Every time you commit, or save the state of your project in Git, it basically takes a picture of what all your files look like at that moment and stores a reference to that snapshot.

As you learn Git, try to clear your mind of the things you may know about other VCSs, such as Subversion and Perforce; doing so will help you avoid subtle confusion when using the tool.

However, this setup also has some serious downsides. The most obvious is the single point of failure that the centralized server represents. If that server goes down for an hour, then during that hour nobody can collaborate at all or save versioned changes to anything they’re working on. If the hard disk the central database is on becomes corrupted, and proper backups haven’t been kept, you lose absolutely everything—the entire history of the project except whatever single snapshots people happen to have on their local

Some of the goals of the new system were as follows: Speed Simple design Strong support for non-linear development (thousands of parallel branches) Fully distributed Able to handle large projects like the Linux kernel efficiently (speed and data size) Since its birth in 2005, Git has evolved and matured to be easy to use and yet retain these initial qualities.

It is widely believed that modern society has a larger quantity of knowledge than more primitive societies, that this quantity of knowledge is growing, and that the knowledge "required" for the average citizen to live in a modern society is also growing.

人,总是跳不出自己的思虑之茧。从这个意义上说,百助和秀隆毫无二致。一个太信任他人,另一个则疑心太盛,可是,两人都没有意识到这一点。

To bring this back to programming languages, one thing that always bothers me is why new ones keep appearing. I start saying things like "I guess language n-1 wasn't that great since language n came along and people jumped to it".

Notice that by making this machine more versatile, we've also slowed it down. Using the same oscillator, it adds numbers at only one-fourth the speed of the first automated adder I showed in this chapter. This is the result of an engineering principle known as TANSTAAFL (pronounced tans toffle), which means "There Ain't No Such Thing As A Free Lunch." Usually, whenever you make a machine better in one way, something else tends to suffer as a result.

夏日的阳光透过树枝的空隙,把刺目的光线投射到地上,使官兵卫想起了方今的秀吉。此人运势极强,又有超群的能耐,今后的动向,值得一睹……

人想不累,秘诀就是乐于辛劳。如你感到疲劳了,可以换另外一件事做。你去通知堺港的茶人,就说近畿一带已经没有战乱了,他们可以放心地享受茶道了。”说罢,他又转过身,对官兵卫和彦右卫门道,“下面咱们谈谈筒井顺庆吧。顺庆已经把人质带来了吗?”

池田胜人低下头,极力不让自己笑出声来。秀吉特意到岐阜城去,用玩偶征服了三法师的事情,众人中只有他一个人知道。秀吉简直就是个孩子…… 可是仔细一想,就会觉得十分可怕。如此细微的地方,他都想到了,世上还会有比他更精明的人吗?在激战之隙,他心中竟然能描绘出一副直到今天才发生的图画,这样的人,岂可久居人下?

秀吉超常的精力,源自他从不把辛劳作为辛劳来看待,在他的胸中,从来就无“辛劳”之辞。他夜以继日,每进一步,都会感到无比的快乐,也感到莫大的欣慰。这种“辛劳之乐”非但不会令人疲劳,只会磨炼人的意志,鼓舞人的精神。从这个意义上来说,秀吉仿佛一名无我之人,而他的喜悦便如登高回望之情。在四十七载沉浮中,他深深地体味到了这种“辛劳之乐”的功效,一直将其奉为座右铭。

Ideas, as the raw material from which knowledge is produced, exist in superabundance, but that makes the production of knowledge more difficult rather than easier.

In much the same way, specks of knowledge are scattered through a vast emptiness of ignorance, and everything depends upon how solid the individual specks of knowledge are, and on how powerfully linked and coordinated they are with one another. The vast spaces of ignorance do not prevent the specks of knowledge from forming a solid structure, though sufficient misunderstanding can disintegrate it in much the same way that radioactive atomic structures can disintegrate (uranium into lead) or even explode.
