KB3035583
Microsoft is pretty sneaky. They camouflage their Windows 10 downloader, KB3035583, as a recommended Windows 7 update with no indication of what good this update does.

This is an exercise I made, just to remind myself of how snapshots and clones work in ZFS. Also, how to properly get rid of them when you’re short of diskspace, or the dataset listing is too long, etc. First, we have the shell script that demonstrates the rise and fall of the initial dataset, […]

The table below is nothing more than an unofficial errata of said book. Beware, what you find below might be due to my lack of understanding FreeBSD, ZFS, or the […]
