Percona 比較 MySQL 與 MariaDB 預設值的差異

Percona 的人花了些時間整理 MySQL 5.7 與 MariaDB 10.2 在預設值上的差異:「MySQL and MariaDB Default Configuration Differences」。

整體可以感覺到 MariaDB 10.2 相較於 MySQL 5.7 還是頗偏 MyISAM 的設計,可能跟 Monty (Michael Widenius) 的偏好有關吧... 不過技術面上來說,MariaDB 10.2 是基於 5.5 分支出來一路改出來的,當時的 InnoDB 跟現在的版本比起來的確沒那麼強...


iOS 11 的無線網路與藍芽關假的讓 EFF 不爽...

這次 iOS 11 的無線網路與藍芽需要到 Settings (設定) 裡面才能有效關掉的設計,讓 EFF 不爽寫了一篇文章:「iOS 11’s Misleading “Off-ish” Setting for Bluetooth and Wi-Fi is Bad for User Security」。

On an iPhone, users might instinctively swipe up to open Control Center and toggle Wi-Fi and Bluetooth off from the quick settings. Each icon switches from blue to gray, leading a user to reasonably believe they have been turned off—in other words, fully disabled. In iOS 10, that was true. However, in iOS 11, the same setting change no longer actually turns Wi-Fi or Bluetooth “off.”

不過藍芽的洞真的不少,儘量避免吧... +_+
