🔴Monday May 17th 2021 🔵2021年5月17日星期一 🔱Espresso - Today’s agenda 每日濃縮 - 今日頭條 💰❓💰Gangnam-style numbers: Berkshire Hathaway’s share price 波克夏海瑟威的股價:與「江南 Style」的關聯? What links Warren Buffett, a revered investor, and Psy, a Korean pop star? On May 4th the Nasdaq exchange was forced to exclude Class A shares in Berkshire Hathaway, the conglomerate headed by Mr Buffet, from its data feeds, as the share price approached $429,496.7295. (Actual trading in the stock, which is listed elsewhere, proceeded.) That number was the largest value 32 binary digits, or bits, could represent in Nasdaq’s software. The limit is the connection to Psy, whose video “Gangnam Style” broke 2,147,483,647 views (the largest 31-bit value) on YouTube in 2014, forcing a programming change. Software engineers strive to anticipate the largest possible number needed in their systems. Yet just as old video games malfunctioned when players hit unforeseen scores, Psy and Berkshire reveal how the unthinkable can become reality. An update to Nasdaq’s systems goes live today: Berkshire Hathaway’s share price will have to exceed $1.8 quadrillion to break them again. 備受尊崇的股神巴菲特 (Warren Buffett) 竟然與南韓流行樂巨星江南大叔 Psy 有關聯?在本月四日,由巴菲特執掌的波克夏海瑟威 (Berkshire Hathaway) 聯合集團的 A 股股價逼近 42萬9,496.7295美元,而美國納斯達克綜合指數 (Nasdaq exchange) (因無法顯示該股價而) 被迫將之移出數據交換服務 (data feeds),至於該股在其他地方上市的實際交易則照常進行。4,294,967,295是採用 32次二進位制的納斯達克電腦軟體系統所能呈現的最大數值。這個限制剛好與 Psy 在 2014年於 YouTube 發表的「Gangnam Style」因衝破 21億4,748萬3,647次點閱數 (此為 31次二進位制最大能呈現的數值) 而迫使 YouTube 更改程式設定如出一徹。軟體工程師極力超前部署系統中所需的最大數值,但就如同舊款的電子遊戲在玩家拿到無法預料的高分後會當掉一樣,Psy 和波克夏海瑟威向世人說明了什麼叫做無法想像的東西也可能成真。今天納斯達克將上線更新後的系統,而波克夏海瑟威的股價則必須站上 1,800兆美元才能再次癱瘓其系統。 ⚜️Daily takeaway⚜️ 每日單字精選 ✅Investor (n.): 投資人 (名) ✅Exclude (v.): 排除、將…排除在外 (動) ✅Conglomerate (n.): 集團、聯合企業 (名) ✅Software (n.): 軟體 (名) ✅Anticipate (v.): 預料、預想、預知 (動) ✅Malfunction (v.): 故障 (動) ✅Unthinkable (adj.): 無法想像的 (形) ✅Exceed (v.): 超過、超越 (動) — ✔︎ 按讚【每日一經濟學人】Facebook 粉專:https://reurl.cc/Lddode ✔︎ 追蹤【每日一經濟學人】Instagram 帳號:https://reurl.cc/Oqqoq3 ✔︎ 訂閱【每日一經濟學人】YouTube 頻道:https://reurl.cc/Y665dX ✔︎ 閱讀【每日一經濟學人】Medium 平台:https://reurl.cc/k00WZr — 🔶如有商業合作或業務需求,請洽:leontheeconomist@gmail.com 🔴如影音內容有誤,歡迎來信勘誤:leontheeconomist@gmail.com
