Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

The Linux Process Journey — “dmcrypt_write”
Overall, “dm-crypt” is a device-mapper target (https://elixir.bootlin.com/linux/v6.5-rc3/source/drivers/md/dm-crypt.c#L3689) supported from kernel version 2.6.4 (https://elixir.bootlin.com/linux/v2.6.4/source/drivers/md/dm-crypt.c). It is responsible for transparent (aka real-time/on-the-fly encryption) block device encryption while using the kernel crypto API (https://gitlab.com/cryptsetup/cryptsetup/-/wikis/DMCrypt) .

Can I only partially clone a LUKS encrypted drive?
References: - Frequently Asked Questions Cryptsetup/LUKS - Question 2.15: "neither dm-crypt nor LUKS1 stores partition size and LUKS2 uses a generic "whole device" size as default." - Stackexchange: What does cryptsetup resize do if LUKS doesn't store partition size?

Is it possible to create a directory that is automatically encrypted at rest?
LUKS is probably what you want

Argon mini fan starts at 55°C but never stops
Fan control generally involves hysteresis. This means a cooling fan turns on at one temperature, and then turns off once temperature has fallen to another lower temperature. This avoids cycling the fan on and off too much. The difference between those two temperatures is hysteresis. The default hysteresis is 10°C and maybe the fan never manages to cool the CPU to 45°C. A parameter has been added to change hysteresis: https://github.com/raspberrypi/linux/commit/fa390133fd17f2cc6aa5a7d2e472c073a1115fe1

Raspberry Pi 5
I see that the PR against the Raspberry Pi linux repo is out [0]. Interestingly they are introducing a BCM2712 defconfig with a 64k default page size.

> It is the most basic task for Linux computer...
Well, it depends for whom. Also, you need adequate software and hardware. About wireless, the chipset in an RPi4 is designed for clients, not APs, and its capabilities on having multiple clients are quite limited:
https://github.com/raspberrypi/linux/issues/3010
Routers like the Omnia Turris, Mikrotik, PC Engines... use specific mini PCIe cards that can be as expensive as a full Raspberry Pi 4, just for the wireless.
