对GH数据结构的理解

一.

单一数据：实线，只有一个数据（点/线/面）

线性数据：空心线，只有一组，一组是有很多面，flatten tree数据包

树形数据：虚线，很多组，每一组包含很多不同类型的数据

二.核心原则

1.数据之间按照顺序计算（对应原则是最低路径内的数据之间的对接）

2.补齐补齐原则是末尾补齐（不只组内数据补齐，组数量也可以补齐）

两组线性数据进行计算是，输入端的数据包之间进行补齐

数据量非最多的数据包补齐数据量至最多数据量数据包的数据量

Interview at the All Things Digital D5 Conference, Steve and Bill Gates spoke with journalists Kara Swisher and Walt Mossberg onstage in May 2007.

Kara Swisher: The first question I was interested in asking is what you think each has contributed to the computer and technology industry— starting with you, Steve, for Bill, and vice versa. Steve Jobs: Well, Bill built the first software company in the industry. And I think he built the first software company before anybody really in our industry knew what a software company was, except for these guys. And that was huge. That was really huge. And the business model that they ended up pursuing turned out to be the one that worked really well for the industry. I think the biggest thing was, Bill was really focused on software before almost anybody else had a clue that it was really the software that— KS: Was important? SJ: That’s what I see. I mean, a lot of other things you could say, but that’s the high-order bit. And I think building a company’s really hard, and it requires your greatest persuasive abilities to hire the best ...

巴菲特致股东信-1976年

笔记：为什么选择轻资产行业：当竞争疯狂时，不会强迫加入降价大战最终选择了费雪的思想，选择能理解的优秀企业，以合理的价格买入并长期拥有翻译：雪球：https://xueqiu.com/6217262310/131440258 备份：https://archive.ph/XLK0S 原文： To the Stockholders of Berkshire Hathaway Inc, After two dismal years, operating results in 1976 improved significantly. Last year we said the degree of progress in insurance underwriting would determine whether our gain in earnings would be "moderate" or "major." As it turned out, earnings exceeded even the high end of our expectations. In large part, this was due to the outstanding efforts of Phil Liesche's managerial group at National Indemnity Company. In dollar terms, operating earnings came to $16,073,000, or $16.47 per share. While this is a record figure, we consider return on shareholders' equity to be a much more significant yardstick of economic performance. Here our result was 17.3%, moderately above our long-term average and even further above the average o...

巴菲特致股东信-1973年

笔记：在上一年度预测的今年竞争加剧导致利润下滑，真的发生了翻译Link：雪球：https://xueqiu.com/6217262310/131257618 备份：https://archive.ph/KIfdT 原文： To the Stockholders of Berkshire Hathaway Inc.: Our financial results for 1973 were satisfactory, with operating earnings of $11,930,592, producing a return of 17.4% on beginning stockholders' equity. Although operating earnings improved from $11.43 to $12.18 per share, earnings on equity decreased from the 19.8% of 1972. This decline occurred because the gain in earnings was not commensurate with the increase in shareholders' investment. We had forecast in last year's report that such a decline was likely. Unfortunately, our forecast proved to be correct. Our textile, banking, and most insurance operations had good years, but certain segments of the insurance business turned in poor results. Overall, our insurance business continues to be a most attractive area in which to employ capital. Management'...

Commencement Address at Stanford University--“Stay hungry. Stay foolish.”

I am honored to be with you today for your commencement from one of the finest universities in the world. Truth be told— I never graduated from college. This is the closest I’ve ever gotten to a college graduation. Today I want to tell you three stories from my life. That’s it. No big deal. Just three stories. The first story is about connecting the dots. I dropped out of Reed College after the first six months but then stayed around as a drop-in for another eighteen months or so before I really quit. So why did I drop out? It started before I was born. My biological mother was a young, unwed graduate student, and she decided to put me up for adoption. She felt very strongly that I should be adopted by college graduates, so everything was all set for me to be adopted at birth by a lawyer and his wife. Except that when I popped out they decided at the last minute that they really wanted a girl. So my parents, who were on a waiting...

Interview with Steve Jobs, WGBH, 1990

Interviewer: what is it about this machine? Why is this machine so interesting? Why has it been so influential? Jobs: Ah ahm, I'll give you my point of view on it. I remember reading a magazine article a long time ago ah when I was ah twelve years ago maybe, in I think it was Scientific American . I'm not sure. And the article ahm proposed to measure the efficiency of locomotion for ah lots of species on planet earth to see which species was the most efficient at getting from point A to point B. Ah and they measured the kilocalories that each one expended. So ah they ranked them all and I remember that ahm...ah the Condor, Condor was the most efficient at [CLEARS THROAT] getting from point A to point B. And humankind, the crown of creation came in with a rather unimpressive showing about a third of the way down...

巴菲特致股东信-1975年

笔记：华盛顿邮报已成为伯克希尔第一重仓股翻译：雪球：https://xueqiu.com/6217262310/131409324 备份：https://archive.ph/4hgK3 原文： To the Stockholders of Berkshire Hathaway Inc.: Last year, when discussing the prospects for 1975, we stated “the outlook for 1975 is not encouraging.” This forecast proved to be distressingly accurate. Our operating earnings for 1975 were $6,713,592, or $6.85 per share, producing a return on beginning shareholders ’ equity of 7.6%. This is the lowest return on equity experienced since 1967. Furthermore, as explained later in this letter, a large segment of these earnings resulted from Federal income tax refunds which will not be available to assist performance in 1976. On balance, however, current trends indicate a somewhat brighter 1976. Operations and prospects will be discussed in greater detail below, under specific industry titles. Our expectation is that significantly better results in textiles, earnings added from recent acquisitio...
