Exclude subdirectories or directories using tar

 Do not add the "/" at the end of the subdirectory which is to be excluded.

For example, the following line will NOT exclude the subdirectory: 

tar --one-file-system --exclude=/home/chiao/.local/share/Trash/  -cvf test_Trash.tar /home/chiao

Instead, it should be like this:

tar --one-file-system --exclude=/home/chiao/.local/share/Trash  -cvf test_Trash.tar /home/chiao

No / at the end of --exclude option.

usb 3.1 gen 1 gen2 ... etc.

 cf: https://www.kingston.com/tw/usb-flash-drives/usb-30

USB 3.1 Gen 1 與 USB 3.1 Gen 2 之比較

USB 3.1 Gen 1 及 USB 3.1 Gen 2 僅在速度上有所不同。USB 3.1 Gen 1 支援高達 5Gbit/s 的速度，而 USB 3.1 Gen 2 支援高達 10Gbit/s 的速度。USB-IF 打算使用不同名稱來稱呼 USB 3.1 Gen 1 和 USB 3.1 Gen 2，以便產品行銷。
他們想要將 USB 3.1 Gen 1 及 Gen 2 分別命名為「SuperSpeed USB」及「SuperSpeed USB+」，但業界並不買單。通常，OEMs 會對其規格表新增 5Gbps 或 10Gbps 的速度，以便在兩個 USB 標準之間作出區隔。業界其他公司則稱呼它們為「USB 3.1 Gen 1」或「USB 3.1 Gen 2」。

 

 

USB 3.2 面世

自此之後，USB 技術便突飛猛進，在 2017 年隆重推出 USB 3.2。USB 3.2 有四類，分別具有不同名稱及意義。四類USB 3.2：

	USB 3.2 Gen 1x1	USB 3.2 Gen 1x2	USB 3.2 Gen 2x1	USB 3.2 Gen 2x2
傳輸速度	5Gbps	10Gbps	10Gbps	20Gbps
先前名為	USB 3.1 Gen 1 及 USB 3.0	--	USB 3.1 Gen 2	--
介面選項	USB-A、 USB-C、 microUSB	僅限 USB-C	USB-A、 USB-C、 microUSB	僅限 USB-C

The solution for me is to set the network interface priority by setting the metric.

System Dynamics

  The level is an accumulation, or integration, or stock, to choose terminology from different fields. The rate is a flow that changes the amount in the level. The rate is defined by a “policy” statement that tells how the rate is controlled by the value of the level in comparison to a goal. All systems, everywhere, consist of these two kinds of concepts --levels and rates--and none other. 

 

Water in a bathtub is a level, the flow of water is the rate that changes the level. A person’s reputation is a level that is changed by the flow of good and bad actions by that person. The degree of frustration in a group is a level that gradually changes in response to surrounding pressures. 

At the point where a rate of flow is being determined, the condition of the system, as indicated by the values of the levels, is compared with a goal to determine control of the flow.  

 

https://en.wikipedia.org/wiki/System_dynamics 

 

A stock is the term for any entity that accumulates or depletes over time. A flow is the rate of change in a stock.
