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 ...

Foobar2000 组件安装教程

原作者博客地址汉化作者 Asion博客关于foobar 2000的一些资源前言 foobar2000 由于其软件架构特点以及开放的姿态，使得第三方很容易开发组件（component）来拓展它的功能。由于在官网下载的默认安装文件只带了少量几个默认的组件，满足不了使用的需求，例如：默认不带 ape，tta，tak 等音频文件格式的解码器，很多无损压缩格式音乐没法播放。所以自己下载安装组件是必备的基本技能。 foobar2000 的中文汉化版（Asion 汉化）为了方便使用，集成了无损压缩文件解码器以及一些其它有用的插件，安装时选上即可，不喜欢折腾的建议使用汉化版。这里组件指的是 foobar2000 标准组件（*.dll 文件），而非 vst 插件等其它插件，姑且把组件分为两类：官方组件：英文版安装包自带，安装时可选择；第三方组件：非官方自带的组件除了 foo_input_std.dll 和 foo_ui_std.dll 这两个组件是必须的外，其它的所有组件都非必需的，可以随需要增删。第三方组件可以去官网、官方论坛或者官方 wiki 去找，也可以去贴吧等地逛逛。下载还是要强调一下，这里说的是 foobar2000 component ，不是中文网上通常说的 vst 插件。下载好的组件包一般是 xxx.zip 或 xxx.fb2k-component 格式的文件，也有用 7z 打包的。前两种都是 zip 压缩（只要把 fb2k-component 改成 zip 文件就变成了 zip：包）。标准状况下压缩包里的内容结构应该是 xxx.zip yyy.dll README.txt (可能没有) LICENCE.txt (可能没有) (其它杂七杂八）除少数外一般只有一个 xxx.dll 文件.一定要注意压缩包结构不能是: xxx.zip yy folder (文件夹） zzz.dll … 否则要解压缩，提取那个 dll 文件。安装方法一（推荐）打开 foobar2000 的菜单文件 > 首选项(file >preferences) 的组件(components...

UNstudio实习经验分享

再过一周，我就将离开UNstudio阿姆斯特丹总部，到其上海分部了，鉴于上海分部目前还不承担设计任务，因此可以视为我UNstudio参与设计的体验即将告一段落。这个实习，原定3个月，后来被要求延长到了6个月，后来又延长到9个月，现在看来最终大概有11个月——那天一问，发现我的合同已经到了9月份了，赶紧声明不能这么长，我8月得回学校了。

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...

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-1974年

笔记：价格战企业的逻辑：需要降价获取销量--->需要降低成本--->怎么降？扩大规模以摊低成本--->提高固定资产投入--->净资产回报率会降低翻译：雪球：https://xueqiu.com/6217262310/131257947 备份：https://archive.ph/5CEP6 原文： To the Stockholders of Berkshire Hathaway Inc.: Operating results for 1974 overall were unsatisfactory due to the poor performance of our insurance business. In last year's annual report some decline in profitability was predicted but the extent of this decline, which accelerated during the year, was a surprise. Operating earnings for 1974 were $8,383,576, or $8.56 per share, for a return on beginning shareholders' equity of 10.3%. This is the lowest return on equity realized since 1970. Our textile division and our bank both performed very well, turning in improved results against the already good figures of 1973. However, insurance underwriting, which has been mentioned in the last several annual reports as running at levels of unsustainable profitability, turned dramatically worse...

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'...

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...

Steve Jobs introduced the iPhone on January 9, 2007.

This is a day I’ve been looking forward to for two and a half years. Link Every once in a while, a revolutionary product comes along that changes everything. And Apple has been— well, first of all, one’s very fortunate if you get to work on just one of these in your career. Apple’s been very fortunate. It’s been able to introduce a few of these into the world. In 1984, we introduced the Macintosh. It didn’t just change Apple, it changed the whole computer industry. In 2001, we introduced the first iPod, and it didn’t just change the way we all listen to music, it changed the entire music industry. Well, today, we’re introducing three revolutionary products of this class. The first one is a widescreen iPod with touch controls. The second is a revolutionary mobile phone. And the third is a breakthrough internet communications device. So, three things: a widescreen iPod with touch controls; a revolutionary mobile phone; and a breakthrough internet communicat...
