The single Radix auricularia japonica snail in my tank decided to reproduce, most likely all on its own. I believe it must have arrived on my Cabomba as an egg (bought about 6 weeks ago), but it’s also possible it actually arrived as a micro-snail and mated with another micro-snail… Now having actually seen how tiny freshly hatched micro-snails are, I don’t think it’s impossible it arrived as one. Below is a look at one of the newly hatched ones (there are over 10 in total) through a microscope. I also included a picture of its eggs. They are embedded in a jelly-like substance, and hidden inside the Cabomba.
カワ(・∀・)イイ!!Same magnification as above. (Different resolution though, so only the same if viewed resized to the same area.) I don’t know if these eggs are fertilized or not. 同じ倍率で卵の写真も撮ってみた。(しかし解像度が違うのでサイズを合わせた場合に限り同じ倍率。なはず。)受精済みなのかどうかわからない。
On KDE 5.28.0, which is currently the version of KDE included in Debian Stretch, you may run into the following problem: if you run IBus (to work with an IME like Mozc or Anthy to type Japanese), you might find that you sometimes lose the ability to input text in KDE/Qt applications (like konsole, or the run bar (krunner) when you press Alt+F2). It looks like you can fix this by running:
ibus-daemon -r -x -d
Since you can still type stuff in applications that don’t use Qt, such as Firefox, typing the above command into a text area in Firefox, copying and pasting (right click, paste) that text into krunner, then using your mouse to select “Command line: ibus-daemon -r -x -d”, you should be able to get input to work again. If you do not have any non-Qt applications, you could switch to the console and instead do:
DISPLAY=:0 ibus-daemon -r -x d
However, you may need a second hack to get Japanese input to work again: open xterm (not konsole) and activate your Japanese IME (which should work just fine). This seems to cause Japanese input to work again system-wide.
英語で書いてもあまり役に立たないでしょうから、日本語バージョンも合わせて書きます。
Debian Stretch に入っている KDE 5.28.0 に、(IBus が稼働している環境では)KDE/Qt 系のアプリケーションに、時々、何も入力できなくなる不具合があるようです。IBus のデーモンを再起動すると直るので、以下のコマンドを実行してみてください。
