製作康普茶時，可以不用紅茶菇，但需要啟動液（有活菌的康普茶）The SCOPY is not necessary when making kombucha (but starter liquid is required)

 

20261022 Thu 阿原在家製作康普茶，使用買來現成的 SCOBY 及起始液體

但是紅茶菇有限，所以上網查詢確認，啟動液是必備的，但紅茶菇可以不用（網有說，醱酵時間會比較長）

這樣就單純多了。

-----------------------

阿原搜尋：

 Does it need scoby when making kombucha

AI:

No, you do not need a solid, pre-formed SCOBY (the rubbery disc or "mother") to start making kombucha, provided you have raw, unflavored starter tea. [1, 2]

The Difference Between the Disc and the Liquid

Starter Tea (The Real Culture): The liquid contains all the live bacteria and yeast (Symbiotic Culture of Bacteria and Yeast) needed to ferment sweet tea. [1, 2]
The Pellicle (The Disc): The rubbery cellulose mat that floats on top is actually called a pellicle. It is a byproduct created by the bacteria during fermentation. [1, 2, 3]

How to Brew Without a Pre-Made Disc

Use Raw Kombucha: Buy a bottle of unpasteurized, unflavored store-bought raw kombucha to use as your starter liquid. [1, 2]
Mix with Sweet Tea: Combine cooled, sweetened black or green tea with the raw starter kombucha in a glass jar. [1, 2]
Grow a New One: Cover the jar with a clean cloth and rubber band. Leave it at room temperature. Over 1 to 3 weeks, a brand-new cellulose pellicle will naturally grow on the surface as the tea ferments into kombucha. [1, 2, 3]

Pros and Cons of Brewing Without a Pellicle

Pros: You don't need to hunt down or buy a physical SCOBY disc. The microbes in the liquid will build one for you. [1, 2]
Cons: Fermentation may start a bit slower, and the initial batch can be sweeter or less carbonated until the new culture builds strength. [1, 2]

You can learn more about growing your own culture from raw tea via guides like Kommbucha or Susan Cooks Vegan. [1, 2]

Would you like a step-by-step ratio and recipe for growing a new SCOBY from a bottle of store-bought raw kombucha?

原來在美國超市見過的 corned beef 跟與玉米無關，是鹽顆粒醃漬的牛肉

今天 (20261027) YT 推播這影片給我，才知道是這麼一回事。之前看到，想不透。此外，也不知道 corn 玉米，加上 ed 可以當動詞或形容詞

昨天是第一次在這校園拉

小時候看到交通號誌強風警告，當時沒看過風向標，以為是管狀巧克力滴下來

 

題外話：在 AI 一秒就可以產出圖形的時代，阿原依然想嘗試傳統的拍照法，因為這樣的照片，帶有人的溫度

(很久以前想拍這照片與影片，終於拍到了)

阿原是幾年前，看過風向標，才知道，風大警告的標誌，就是風向標，不然，幾十年來，以為是小時候的一種巧克力零食，流出來的樣子。

一來阿原沒見過風向標，無法理解那是怎樣的東西，二來就用生活上的經驗來解讀這個圖形，那就是小時候的零食，管狀巧克力，看成巧克力流出來的樣子。

使用 ffmpeg 移除影片音軌的指令與參數

 

使用 FFmpeg 移除影片聲音（不重新編碼、速度最快），請在終端機或命令提示字元中執行以下指令： [1, 2]

bash

ffmpeg -i input.mp4 -c:v copy -an output.mp4

Use code with caution.

指令參數說明：

-i input.mp4：指定輸入的原始影片檔案（請自行替換檔名）。
-c:v copy：直接複製原有的視訊（Video）編碼，不重新轉檔，保持原本畫質且速度極快。
-an：Audio none 的縮寫，代表捨棄/移除所有音訊串流。
output.mp4：輸出的新影片檔案名稱。 [1, 2, 3]

如果你需要批次處理資料夾內的所有影片，或是想保留特定音軌而只移除其中一條，可以告訴我，我會提供對應的指令給你。

阿原測試

-i %f  -c:v copy -an %b-remove-sound.mp4  ----經過測試，難得一次就成功，讚

檔案管理員 caja-action-configuration-tool (LinuxMint Mate 22.3) 的設定， 讓其他 user 也可以使用

-------

20261026 0745  依照 AI 的建議指令，順利成功。

---------- 

前言：請見另一篇。阿原的電腦會開數個使用者（一個出問題，登入其他帳號，也許還有救），

搜尋：使用 caja-action-configuration-tool 設定 可以用在每個 user

AI:

要讓使用 caja-action-configuration-tool（Caja Actions）建立的右鍵選單設定套用到系統中的每一個使用者，核心方法是將產生的 .desktop 設定檔移至系統全域的目錄中。

以下是具體的實作步驟：

1. 導出或尋找設定檔

當您在圖形介面（caja-action-configuration-tool）中建立好動作後，這些設定預設會儲存在目前使用者的個人目錄中：

路徑：~/.local/share/file-manager/actions/

2. 將設定檔移至全域目錄

若要讓所有使用者都能使用，必須將這些 .desktop 檔案複製到系統全域的 Caja Actions 目錄。

打開終端機（Terminal）。
建立全域的動作目錄（如果不存在的話）：
bash
sudo mkdir -p /usr/share/file-manager/actions/
Use code with caution.
將您個人目錄下的所有設定檔複製過去：
bash
sudo cp ~/.local/share/file-manager/actions/*.desktop /usr/share/file-manager/actions/
Use code with caution.

3. 設定正確的檔案權限

為了確保其他使用者有權限讀取這些設定，請調整該目錄與檔案的權限：

bash

sudo chmod 644 /usr/share/file-manager/actions/*.desktop
sudo chmod 755 /usr/share/file-manager/actions/

Use code with caution.

4. 驗證與重啟

完成上述步驟後，請讓其他使用者登入，或者在其他使用者的帳號下重啟 Caja 檔案管理器來載入新選單：

bash

caja -q

Use code with caution.
