A unnamed sci fi novel I'm working on during my vacation. These are the first 2 chapters.

I’m thinking of going with the rotation to ‘speed up’… the air being stationary over the earth. If we could fly higher. Using rocketry we’d have the effect. Where going against the rotation reduces time to destination for most places.

It’s an interesting idea. For long distance travel, going with the wind could make things more efficient.

down a rabbit hole. In the object header, it does the Fletcher Checksum. It uses a magic number to assure that the container decodes correctly after being encrypted, I think. It's necessary because OS is on a separate volume to data.

internally, it's using Fletcher Checksumming. Which I'm familiar with. I have a C# version of it. It works in bytes only. Which is weird. Because the timestamping of the apfs filesystem is supposed to be really accurate.

i started out with a stupid question. thinking that apple silicon might be designed for features in apfs. Of course it's a kernel driver for exfat and a kernel driver for apfs... handled at the operating system level and not to do with the x86 command set.

A lot of their stuff is super secure, but that filesystem seems pretty open.

APFS can't separate memory. It can't because the free space within the drive container is shared amongst all the partitions. I don't see why writing to the system protected regions of the operating system would be any more difficult than writing to userspace.

it's using binary trees. File operations are atomic. I mean it's really clever and quite stupid at the same time. some stupid things: disk degradation any sort of attack on a file that's used a lot, brings down a whole lot more but it would be fast and light.

ugh, copy on write... apfs metadata pointer modifying copy code... (if you copy a file, it doesn't copy, it only writes changes from the original file when changes are made... while both copies point to the same memory...)

I have fast devices. Just some things I do absolutely chew data. Nom nom nom, 2 hours of munching on my i5 Mac. 43 minutes on my 9950x pc. My laptop I’m coordinating with.

I'm reminded of the idea of the muses. That creativity comes from a spiritual place. Waiting like a stalking butler. Mother Mary won't you whisper. Something but what's past and done... I haven't heard this song in a while. It's so good.
