  • The Web3 Fraud https://www.usenix.org/publications/loginonline/web3-fraud
    本来想写一些积极正向的，没想到，都是负向......
    文章核心论点是：1）Web3并没有减少原始的ISP任意一方，反而增加了Web3信任链一方的复杂度；2）Web当前的存储、计算都很慢，很昂贵（比ECS，树莓派都要差很多）

  • 我们有 3 亿美国人每天看 5.5 小时的电视，而不是视频。 我不包括 TikTok 和 YouTube，只是电视。

  • YouTube Shorts 有 1.5B 的 MAU

  • 4月份，Netflix 以 6.6% 的电视观看时间份额在流媒体中排名第一，其次是 YouTube（6.1%）、Hulu（3.3%）、亚马逊的 Prime Video（2.5%）和 Disney+（1.7%） %）

  • 以太坊的一秒钟计算成本为 250 美元
    向以太坊区块链写入一条 3kB 消息的成本与在亚马逊上为整个 1TB 以太坊区块链存储一年的价格相同。 或者与购买 1 TB M.2 SSD 的价格相同。
    好贵，肉疼

  • 根据律师媒合平台 Contract Counsel 的资料库，美国律师的每小时平均收费是 250~350 美元。

  • 「只要 2.5%-3% 的用户有付费就足以支持 Telegram 的所有支出。」 ————Telegram 创办人 Pavel Durov

    • Telegram 有多少用户数？官方的最新数字是 7 亿月活跃用户。7 亿的 2.5%-3% 是 1,750-2,100 万，每年的 premium 订阅费用是 60 美元，因此可得 Telegram 的全年支出约是 10.5 亿-12.6 亿美元

  • 根据 IDC 的推估，全世界最畅销的 VR 显示器 Quest 2 其累积销售量已近 1,500 万台。对比一下，Xbox Series X & S 的推估销量是 1,400 万台

  • 根据 Steam 2021 年度回顾数据，Road to VR 推估 Steam 平台上的每月活跃 VR 显示器约为 300 万台，其中 Quest 2 占了 47%，Rift S 占了 12%，而以上两者都是 Meta 的产品。​​

  • 知名虚拟社交应用 Rec Room 日前公布使用 VR 显示器的月活跃用户数达 300 万人。

  • 「如果就业部门诚实的话，到七月上旬所有学校都毕业的时候，还没有工作的毕业生应该超过400万，这个估计已经很保守了。」 ——黄天华

  • “如果你选择利用自己的地位和影响力，去为那些没有发言权的人发声；如果你选择不仅与强者为伍，还会同情帮扶弱者；如果你时刻设身处地为那些没有像你这般地位的人着想，那么你的存在，将不仅是你家人的骄傲，更是无数因为你的帮助而改变命运的成千上万人的骄傲。” ——J.K.罗琳

  • 「名气和金钱之间存在巨大差距。大多数人的名气比他们的财富要大，而且许多人并不如你想像的那样赚钱。不论任何时候，电影演员协会中 99% 的成员都是处于失业状态。在体育领域，前 2% 的运动员赚取了所有收入的 99%。在音乐领域，前 1% 的创作者赚取了 90% 以上的音乐会收入。对很多人来说，像 Cameo 这样直接面向粉丝的收入来源是唯一能让他们维持生计的东西。」​ ————Cameo创办人Steven Galanis

  • 短影音以及基于用户兴趣的推荐系统是 TikTok 的核心，而我也常认为与其说 TikTok 是「社交平台」，不如说它是「娱乐平台」，使用体验更像「转不完台的有线电视」。​

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...

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-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...

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'...

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...
