Probably, it's because of ZFS ARC (Adaptive Replacement Cache). It's similar to Linux's page cache, can be claimed back any moment and different tools name it differently: https://www.linuxatemyram.com/

On my e-book I use KOReader and I uploaded dictionaries of my personal choice on it. When I see a new word, I hold a finger for a bit longer than usual and KOReader opens a modal window with a definition from Cambridge Advanced Learner's Dictionary. It took some time to find a DRM-free version and convert it into StarDict format but I've done it so I can share you only need to use this Python script: https://github.com/ilius/pyglossary. I'm sure there's already a wiktionary stardict on the web and you won't need pyglossary.

KOReader can be installed on many popular e-readers, including jailbroken Kindles (this usually takes 10 minutes to do depending on Amazon mood).

I migrated to another country and it's hard to talk with parents, my sister and grandmas as much as I did when I was back home. We tried making weekly calls to talk and play games but someone could never make it. I got an idea to create a small chat, share a simple topic every morning and then let everyone take a picture of the object. For example, recently we had "Garden" which made my grandma in the countryside go outside and take a picture of her growing strawberries. Today is "Anything halal" and I hope this will make another (Muslim) grandma in the chat happier :-)

At first, all topics were made up by me. Then, I made it possible for others to suggest topics via a simple bot. I showed this chat to friends and they got excited and wanted to try the same so I upgraded the bot to support multiple chats. Since November 2025, it's hosted 11 chats and if you're interested, you can try it too.

It's free and won't be abandoned tomorrow because I personally use it.

Consider trying redo[0]. It's an idea of D. J. Bernstein (a.k.a. djb) what could already be a good advertising.

Your problem can be solved with make as it pointed by others but I see a wonderful example where redo's target files are pretty clear describing what redo can do.

redo's target files are usually SHELL-scripts but they can be whatever you want if it can be executed by a kernel. `redo-ifchange file1` is a command which waits until file1 have been rebuilt or, by other words, waits until a file1's target file have been executed if it requires.

There are 4 target files to show how to solve your problem --- downloading and merging two files:

all.do file is

  DEPS="foo.json bar.json"
  redo-ifchange $DEPS
  jq -s '.[0] * .[1]' $DEPS

  curl "http://example.com/foo.json"  # redo guarantees that any errors won't update foo.json as it can happen in make world.

  curl "http://example.com/bar.json"

I'd recommend getting started with a Go version of redo --- goredo[1] by stargrave. There is also a link to documentations, FAQ and other implementations on the web-site.
