iOS 透過無線網路的 RCE...

在「About the security content of iOS 10.3.1」這邊的說明:

Available for: iPhone 5 and later, iPad 4th generation and later, iPod touch 6th generation and later
Impact: An attacker within range may be able to execute arbitrary code on the Wi-Fi chip
Description: A stack buffer overflow was addressed through improved input validation.
CVE-2017-6975: Gal Beniamini of Google Project Zero

這描述看起來就不太妙...

配合 Touch ID 的 sudo

大概是新的 Macbook 出來後想出來的點子?透過 Touch ID 驗證 sudo 權限:「A fork of `sudo` with Touch ID support.」。

sudo-touchid is a fork of sudo with Touch ID support on macOS (powered by the LocalAuthentication framework). Once compiled, it will allow you to authenticate sudo commands with Touch ID in the Terminal on supported Macs (such as the late 2016 MacBook Pros).

這點子好像還不錯 XDDD

Linux 下多點觸控的設定

看到「Multitouch gestures with libinput dirver on X11, Linux」這個專案,可以在 Linux/X11 下偵測到多點觸控,然後設定對應的按鍵,從他的設定檔就可以看到這套軟體的功能了:

swipe:
  3: 
    left: 
      shortcut: 'alt+Right'
    right: 
      shortcut: 'alt+Left'
    up: 
      shortcut: 'ctrl+t'
    down: 
      shortcut: 'ctrl+w'
  4:
    left: 
      shortcut: 'super+Right'
    right: 
      shortcut: 'super+Left'
    up: 
      shortcut: 'super+a'
    down: 
      shortcut: 'super+s'
pinch:
  in:
    shortcut: 'ctrl+plus'
  out:
     shortcut: 'ctrl+minus'

不知道實際跑起來如何 @_@

MBPR 觸控板壓力回饋失效的問題

Short Version:遇到這個問題,只要把作業系統從 10.10 更新到 10.12 就好了:「Mac Users Reporting Widespread System Freezes With OS X El Capitan 10.11.4 Update」。


之前 MBPR 在過保後掛過一次送修 (常常無法開機,開起來後鍵盤與觸控板都沒有反應),當時把鍵盤與觸控板都換掉... 結果前幾天發生觸控板的壓力回饋失效的問題 (還是可以移動滑鼠游標與輕觸),但這幾天要去日本,想帶著處理事情,就先上 24h 買個 Magic Mouse 2 應急 (用 lightning 充電的那個版本,被嘲笑很醜的那個 XD)。

買回來後發現 Magic Mouse 2 的多點觸控與電量資訊沒有顯示在系統裡,翻了資料才發現要 10.11 之後的版本:

Bluetooth-enabled Mac computer with OS X v10.11 or later

耐著性子升級想說出國前至少把問題解決一些,升完後發現觸控板的回饋就回來了... 然後查資料發現是系統的 bug 造成的:

The freeze seems to affect not only the screen and mouse cursor but also the Mac's Force Touch trackpad, which completely loses feedback.

好吧就這樣吧 orz
