How to build a cartesian product from vectors in a single formula with spilled array.

Suppose that you have a set of row vectors and want to build a cartesian product of them on Microsoft Excel.　You can build it with a single formula with spilled array. It may require newer versions of Excel. Columns of each rows don't have to be the same. Of course you can use VSTACK to build an input on the fly, or use spilled range operator like A1# if possible. If your input data contains commas, you can modify the formula by replacing the comma separator in both &","& and TEXTSPLIT(B,",") with any character that won't appear in your data (for example, using a pipe symbol | or semicolon ;).

INPUT, A1:M2,

I encountered some strange behaviors on HP Elitebook 830 G8 (CPU: TigerLake) upon installing Debian Bookworm with Xfce desktop environment. Such as:

• Audio volume is set to 100% after suspend / monitor sleep.
• The output doesn't automatically switch when a new device is connected.

To find the cause of the problems, I checked journalctl and I found:

anthyでユーザ辞書にエントリを追加できないとき

空ファイル~/.anthy/private_words_defaultを作成してkasumiで単語登録する。初回はCLIでkasumi -aを使う方がいいかもしれない。理由は、エラーが出て失敗したことがわかりやすいため。anthy-unicodeとkasumi-unicodeでも同じように働く思われる。

When you can't add a word to user dictionary of anthy

Put an empty file as ~/.anthy/private_words_default and now you can add a word to user dictionary with kasumi. Maybe it's good to use kasumi -a on the terminal for the first time because it will raise an error. It should work on anthy-unicode and kasumi-unicode as well.
