  • 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。

  • 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」。​

Apple's One-Dollar-a-Year Man, By Steve Jobs, 2000

(FORTUNE Magazine) – Now that Steve Jobs has showed his hand on Apple's Internet and system software strategies and dropped the "interim" from his title, other questions loom. He's always denied it, but isn't it true that his old company, Next, did wind up taking over Apple? Will there ever be an encore to the 15-year-old Macintosh? Short of that, does Apple have any plans to jump into the "Internet appliance" fray? Will Apple ever build computers for business people again? And what, pray tell, does Steve think of all these young Internet zillionaires? Let's ask. Practically every technology that your old company, Next, possessed when Apple acquired it in 1997 is now being used by Apple in some strategic way. This must seem like sweet vindication.  The thing about Next was that we produced something that was truly brilliant for an audience that our heart really wasn't into selling to--namely, the enterprise. I suppose if you were wr...

《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...

A Sister’s Eulogy for Steve Jobs

I grew up as an only child, with a single mother. Because we were poor and because I knew my father had emigrated from Syria, I imagined he looked like Omar Sharif. I hoped he would be rich and kind and would come into our lives (and our not yet furnished apartment) and help us. Later, after I’d met my father, I tried to believe he’d changed his number and left no forwarding address because he was an idealistic revolutionary, plotting a new world for the Arab people. Even as a feminist, my whole life I’d been waiting for a man to love, who could love me. For decades, I’d thought that man would be my father. When I was 25, I met that man and he was my brother. By then, I lived in New York, where I was trying to write my first novel. I had a job at a small magazine in an office the size of a closet, with three other aspiring writers. When one day a lawyer called me — me, the middle-class girl from California who hassled the boss to buy us health insurance — and said his cl...

巴菲特致股东信-1980年

 笔记： 会计中对于下属股权公司的记账方式有3种： 持股50%以上，全部并入 持续20%--50%，则按持股比例并入 持股20%以下，则以实际收到的利润返还，计入报表 这种会计方式，会导致伯克希尔旗下，不少的企业，未能暴露实际的收益情况 对伯克希尔而言，对盈余的认定并非取决于持股比例是100%，50%，20%，5%或是1%，盈余的真正价值在于其将来再投资所能产生的效益 我们宁愿将所赚的盈余继续交由不受我们控制的人好好发挥，也不希望转由我们自己来浪费 高通货膨胀等于是对投入的资本额外课了一次税 翻译： https://xueqiu.com/6217262310/131837878 https://archive.ph/XMX5n  原文： Buffett’s Letters To Berkshire Shareholders 1980 巴菲特致股东的信 1980 年 Operating earnings improved to $41.9 million in 1980 from $36.0 million in 1979, but return on beginning equity capital (with securities valued at cost) fell to 17.8% from 18.6%. We believe the latter yardstick to be the most appropriate measure of single-year managerial economic performance. Informed use of that yardstick, however, requires an understanding of many factors, including accounting policies, historical ca...

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'...
