- FreeBSD 的 access control framework （類似於 selinux） https://wiki.freebsd.org/Capsicum
- 似乎不錯的二手手機認證購買網站 https://reebelo.com.tw/
- Android 上面可以 hook Java API 餵假資料給 app 的模組 https://github.com/M66B/XPrivacyLua
- OpenBSD 上給 process 自願拋棄執行特定 system call 權力的 system call ，應用程式啟動的時候可以 pledge （發願？）說我不會用某些 system call ，如果未來程序被 hijack ，便可以控制損害範圍。 pledge 的系統設計簡單，功能很少，但是比 selinux 好懂多了 https://man.openbsd.org/pledge.2
- CCC 的演講，介紹歷史上許多新穎設計的作業系統 https://media.ccc.de/v/rc3-525180-what_have_we_lost
- OpenZFS, 開源的，不基於 Solaris 的 ZFS 實作，現在用於 Linux, FreeBSD, Illumos https://openzfs.org/wiki/Main_Page
- Illumos : Solaris 的後繼 project https://illumos.org/
- 2007 年的演講，介紹 mac os x 的核心架構 https://www.youtube.com/watch?v=2M_u0BDHttg

- 關於 Optane 的介紹（中文): https://www.youtube.com/watch?v=TbkuBpXXhfA

以下是 Pellaeon hand-by-hand 指導下的筆記:

sudo zpool create test001
sudo zpool create test001 /dev/sdb
sudo zpool create -f test001 /dev/sdb
sudo zpool status
sudo zfs create test001/data001
sudo zfs list
sudo zpool add test001 /dev/sda

- zfs 有 compression 功能:
- 當 compression 開啟後，存入的檔案會壓縮。關閉之後，就不會壓縮。但不會動到已存入的既有資料。也就是設定是動態生效於該設定期間。
-

zfs set compression=gzip example/compressed

### ZFS

基本理解： https://arstechnica.com/information-technology/2020/05/zfs-101-understanding-zfs-storage-and-performance/

- vdev：一個可以存資料的實體裝置，通常是一整顆硬碟，但是要指定一個分割區為 vdev 也可以
- pool (zpool) 是 vdev 的任意組合
- pool 裡面需要再建立 dataset
- dataset 大致上一個檔案系統的概念, 一個 dataset 都是可以 mount 對象
- snapshot 只能針對一個 dataset
- ashift 是一個 pool 選項，一旦 pool 建好了，就不能改

- https://blog.haostudio.net/hwp/%E5%9C%A8freebsd-%E5%BB%BA%E7%AB%8B-zfs-%E8%A8%98%E9%8C%84/
- https://www.reddit.com/r/zfs/comments/nkbx6g/should_i_use_64k_blocksize_ashift16_for_samsung/
-

### 字型
- Linux 字型要好看的重點改善方向
- 1. 使用適合的字型替代應用程式指定的 windows/mac 專有字型
- 2. 依照語系設定選擇適合的字型顯示 sans-serif , serif, monospace 等「字型類別」的指定
