Steve Jobs at 44, By Michael Krantz, 1999

Differences and Similarities Between Apple and Pixar Apple turns out many products--a dozen a year; if you count all the minor ones, probably a hundred. Pixar is striving to turn out one a year. But the converse of that is that Pixar's products will still be used fifty years from now, whereas I don't think you'll be using any product Apple brings to market this year fifty years from now. Pixar is making art for the ages. Kids will be watching Toy Story in the future. And Apple is much more of a constant race to continually improve things and stay ahead of the competition. His Role At Pixar At Pixar my job is to help build the studio and recruit people and help create a situation where they can do the best work of their lives. And to some degree it's the same at Apple. But at Pixar, I don't direct the movies, whereas at Apple probably, if I had to pick a role out of a film production, I'd be the director. So it...

《Becoming Steve Jobs》Chapter 12 Two Decisions

Jim Collins, the bestselling author of the management classics Built to Last: Successful Habits of Visionary Companies and Good to Great: Why Some Companies Make the Leap … and Others Don’t, has a wonderful phrase to describe an essential characteristic of great leaders: deep restlessness. Collins applies the phrase to Steve, one of the two great leaders who inspire him the most (the other is Winston Churchill, the great English politician who was prime minister during most of World War II, from 1940 to 1945, and again from 1951 to 1955). Collins believes this restlessness is far more important and powerful than simple ambition or raw intelligence. It is the foundation of resilience, and self-motivation. It is fueled by curiosity, the ache to build something meaningful, and a sense of purpose to make the most of one’s entire life. 自己何其有幸，在不到30的年纪，就能感受到乔布斯的心境 “The things he was trying to do,” says Collins, “were always hard. Sometimes those things beat him up. But the response to fighti...

《Becoming Steve Jobs》Chapter 15 The Whole Widget

What the world did see was an effective and visionary leader at the height of his powers. These were complicated years for Apple, but Steve handled almost every challenge in exactly the manner he wanted. He had fallen into leadership at such a young age, but he was comfortable in that role now, and justifiably sure of his capacity to guide Apple’s tens of thousands of employees to the goals he set for them. During these years, he would ensure the company’s continued success in personal computers by engineering a deft switch to a new kind of microprocessor; ruthlessly and successfully managing some major transitions in his executive team; and optimizing and building upon the efficiency and ambition of the company’s product development “treadmill,” as Tim Cook describes it. This is also when he delivered what is likely to be remembered as the most notable product of his life, the iPhone, and then improved even that by pivoting once again into a strategy he personally had not wanted to pu...

产品随想 | 陪读《Make Something Wonderful：Steve Jobs in his own words》1976-1996

There’s lots of ways to be, as a person. And some people express their deep appreciation in different ways. But one of the ways that I believe people express their appreciation to the rest of humanity is to make something wonderful and put it out there. And you never meet the people. You never shake their hands. You never hear their story or tell yours. But somehow, in the act of making something with a great deal of care and love, something’s transmitted there. And it’s a way of expressing to the rest of our species our deep appreciation. So we need to be true to who we are and remember what’s really important to us. ──Steve, 2007 Introduction by Laurene Powell Jobs Much of what’s in these pages reflects guiding themes of Steve’s life: his sense of the worlds that would emerge from marrying the arts and technology; his unbelievable rigor, which he imposed first and most strenuously on himself; his tenacity in pursuit of assembling and leading great teams; and perhaps, above all,...

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...

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...

《Becoming Steve Jobs》Chapter 11 Do Your Level Best

As a mass-market consumer electronics device, the iPod would eventually be sold, of course, all the usual places: Best Buy, Circuit City, big-box department stores, and even the computer retailers like CompUSA. Steve disdained all these outlets. His obsession with his products continued well after they’d been manufactured. The tacky, low-margin hustle of these chains ran completely against the minimalist aesthetic of his products and the clean exuberance of his marketing. There was only one place where he really enjoyed seeing his products sold to the public: his own Apple stores, which had debuted four months ahead of the iPod. 觉得那些喧嚣、嘈杂的零售渠道，配不上自己极美的产品 Going back as far as the debut of the Mac, Steve had always groused about the way Apple computers were sold in its resellers’ stores. The way his computers were displayed and sold represented the very worst of what could go wrong when things weren’t done his way. The salespeople, always interested in quick turnover, seemed to make litt...

《Becoming Steve Jobs》Chapter 16 Blind Spots, Grudges, and Sharp Elbows

Steve could be pretty thin-skinned when someone prominent criticized the aesthetics of his products. He took great umbrage that Neil would, as Steve put it, “pop off in public like that without coming to talk to us about his technical concerns first.” From that point on he had rebuffed all of Neil’s attempts to smoke the peace pipe. 有趣 He had blind spots, grating behavioral habits, and a tendency to give in to emotional impulse that persisted his entire life. These characteristics are often used to make the case that Steve was an “asshole” or a “jerk,” or perhaps simply “binary”—that odd adjective often used to convey the sense that he was half asshole/half genius from birth to death. These aren’t useful, interesting, or enlightening descriptions. What’s more illuminating is to take a look at the specific ways in which Steve failed to do an effective job of tempering some of his weaknesses and antisocial traits, and to consider how, when, and why some of them continued to flare up even...
