vm.swappiness 設成 1 或是 0 的差異

在「MongoDB System Tuning Best Practices」這份投影片裡面看到: To avoid disk-based swap: 1 (not zero!) 以及: ‘0’ can cause unpredicted behaviour 在 kernel 的說明文件是這樣描述,設成 0 時表示只有在避免 oom 時才會 swap: This control is used to define how aggressive the kernel will swap memory pages. … Continue reading

Debian 的 CloudFront

剛剛看到 Debian Mirrors via CloudFront 這個,原來 AWS 幫忙付掉了: This service is kindly hosted by and paid for by Amazon Web Services, and we thank them for their contribution to Debian. 翻了 mailing list 發現是在 2013 年五月的時候弄出來的:「Debian archive distribution via CloudFront … Continue reading

debootstrap 可以把所有檔案都裝到 /usr 下了

從「You can now try merged /usr in Debian」這邊看到,早期因為硬碟空間比較小的關係,會切成 /bin、/usr、/lib 之類的目錄: The original impetus for requiring these directories was due to space limitations in the first Unix implementations, developers favoring the change point out. 這個理由很明顯已經消失了,所以 Debian 就規劃要整併起來...

保護 macOS 的方法

在「drduh/macOS-Security-and-Privacy-Guide」這邊列出了許多保護方式,如果考慮到 APT 的話應該是個不錯的指南... 不過考慮到相當硬,服用前請小心,有些步驟甚至需要拆機: 雖然整篇文章還頗硬的,但裡面講軟體的部份還是很不錯的指南,可以保護自己...

Amazon WorkSpaces 可以透過瀏覽器直接存取了

應該是 AWS re:Invent 前夕,有不少東西都先發表出來了... 這次是公開 Amazon WorkSpaces 可以透過瀏覽器登入操作了:「New – Web Access for Amazon WorkSpaces」。 話說回來,後來才知道這種服務是配著像是「Amazon WorkSpaces with HP Zero Client Computing」這樣的硬體在用... 不過對於靠電腦吃飯的還是用 Laptop 或是 Desktop 會比較順暢就是了 :o

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 … Continue reading

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: … Continue reading

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 … Continue reading
