LinkedIn 在 2012 年的密碼外洩比想像中嚴重，超過一億筆帳號密碼洩漏
在「Another Day, Another Hack: 117 Million LinkedIn Emails And Passwords」這邊看到 LinkedIn 在 2012 年的帳號密碼外洩情況比想像中嚴重許多，當時大家認為只有 650 萬筆資料洩漏，但實際上在 2016 年的現在被確認有 1.17 億筆。 官方也確認 2016 的這份洩漏是正確的，兩份公告在： An Update on LinkedIn Member Passwords Compromised (2012) Protecting Our Members (2016) 很多人都收到 password reset 信件了...
LinkedIn 的工程師分析 TCP Anycast 技術的穩定性與效能
LinkedIn 的工程師測試了 TCP Anycast 技術的穩定性以及效能：「TCP over IP Anycast - Pipe dream or Reality?」。 由於 stateless 再加上一個封包就傳的完的情況下，Anycast 技術被用在 DNS 上已經很長一段時間了，目前大多數 CDN 業者也都有用 Anycast 技術加快 CDN 的回應速度。 但 TCP 因為 stateful，如果 router 上採用的方式有問題，那麼就會導致封包可能會送到不同節點，這會是個嚴重的問題。不過很早之前，幾乎所有的骨幹 router 都已經支援 flow-based load balancing policy： Most routers now … Continue reading
LinkedIn 依照他們的資料對美國的大專院校排名
在 Slashdot 上看到 LinkedIn 對美國的大專院校排名：「Be True To Your CS School: LinkedIn Ranks US Schools For Job-Seeking Programmers」。 軟體工程師的部份在這邊：「LinkedIn 大學排名 — 軟體開發人員」。Slashdot 上的 comment 瞬間就戰起來，然後還有人跑出來問怎麼沒有美國外的資料 XDDD CMU 第一名不算奇怪，但 Stanford 意外的後面？

WebScaleSQL
WebScaleSQL 是 Facebook、Google、LinkedIn 以及 Twitter 四家公司對 MySQL 5.6 的 fork。 而 Percona 的人也針對 WebScaleSQL 與 Percona Server 5.6 的比較，寫了一篇技術分析的文章：「A technical WebScaleSQL review and comparison with Percona Server」。 Percona 那篇分析文章提到不少改善屬於比較激進類型，對於 Percona Server 以及 MySQL 官方版本的定位並不適合。 而在開發上，語法也換到 C99 與 C++11，也就是打算拋棄很舊的系統 (沒有 C99/C++11 … Continue reading
