I think this is a really bad idea unless paired with some regime that penalizes inappropiate use of alarms - and most societies don't treat noise pollution as a real problem. For example, people honk all the time even when there are no

Can you explain this in more detail? It doesn't seem true on a first glance. If you enable compression on ZFS that runs on top of dmcrypt volume, it will naturally happen before encryption (since dmcrypt is the lower layer). It's

Could you have instead changed your code? It's generally best to assume that it's not possible to delete secrets once they are shared (after all, in worst case, the driver could have just remembered the code from the previous visi

You can also share arbitrary binary data between processes by using shared memory (e.g. Python has support for this in multiprocessing.shared_memory module).

fsync is still a bit slow on BTRFS (on ZFS too, but to a smaller degree). For example, I just did a quick benchmark on Linux 5.3.0 - installing Emacs on fresh Ubuntu 18.04 chroot (dpkg calls fsync after every installed package). ext4 - 33s,

You don't need fsync if you only care about your user process being killed. It protects only against power loss/kernel crash - the filesystem is not running as user process, so it can't be killed.

I think it shouldn't be hard to do that automatically in software - you only need to know exchange rates at time of every transaction.

- fsync on btrfs is extremly slow. The situation has improved in last 3 years, but it is still much slower than ZFS. I just did a simple test and BTFS is 12x slower than ZFS (on my customer SSD, for small writes). - RAID5/6 mode is onl
