httm VS tmux

My projects and many projects include a THIRD-PARTY-LICENSES.html file when I distribute binaries. See: https://github.com/kimono-koans/httm/blob/master/third_party/LICENSES_THIRD_PARTY.html

The only real advantage I can think of with nested ZFS is that the files in the KVM would obviously be individual inodes in the nested ZFS filesystem and datasets, in addition to the one inode per virtual volume on the hypervisor (or zvol). This would allow for granular file management on the kvm and the use of tools like https://github.com/kimono-koans/httm which is like a command line time machine for ZFS.

Yes, but the trigger feature, block cloning, only landed in the latest 2.2 release. If you immediately hopped on 2.2, and used a system with lots copy_file_range and FICLONE use, yes, you may have a problem (like, as you note, on Gentoo, where this problem surfaced).

Most people were just hopping on the bandwagon. My distro ships 2.1.5, so I have a 6 month wait until this feature lands, so I was just building copy_file_range support into my ZFS apps, right before news of this bug hit.[0]

> There are other things required to trigger the bug that are a lot less common though.

Exactly. My guess is the incidence of this will exceedingly rare for the common user/small NAS user/etc. I've run a corruption detector[0], and what I've found mostly indicates false positives. Some are build artifact fingerprints, which I don't care about, and which were deleted with the next build. The ones with an extant file on another system, I confirmed were a diff match with the origin using `rsync -rincv` and whats on snapshots with `httm --map-aliases`. So far no positive matches.

cargo install --git https://github.com/kimono-koans/httm --branch clones strace -f -o stderr.txt -e ioctl -- httm -r -R ~/.zshenv

httm prints the size, date and corresponding locations of available unique versions (deduplicated by modify time and size) of files residing on snapshots, but can also be used interactively to select and restore files, even snapshot mounts by file! httm might change the way you use snapshots (because ZFS/BTRFS/NILFS2 aren't designed for finding for unique file versions) or the Time Machine concept (because httm is very fast!).

All btrfs snapshot tools can have different layouts. It's mostly a nightmare for any one tool to support. Although its not the tool you're looking for, FYI AFAIK httm supports all/most btrfs layouts, but it took more work than necessary to get there.

ZFS only option which requires super user privileges.

httm - Interactive, file-level Time Machine-like tool for ZFS/btrfs/nilfs2

This got me thinking about my recent pivot, my switch to Neovim by way of LazyVim to write most of my code, and using tmux to keep terminal states alive after closing a session.

I use Tmux. It's a terminal-agnostic multiplexer. Gives you persistence and automation superpowers.

Having a common set of tools already set up in different windows or sessions in Tmux or Zellij is obviously an option, but there is a subset of us ( 👋 ) that would rather just have fingertip access to our common tools inside of our editor.

Once you have your Mac or Linux machine ready, make sure to downlaod and install TMUX (Terminal Mulitplexer). A lot of our scripts are going to be running headless inside of a TMUX session as it's an incredibly clean way to manage and organise different workspaces simultaneously. A lot of our scripts will help us to interact with TMUX so don't worry if it looks a little intimidating at first. You can install TMUX using your package manager in the terminal, use whichever applies to you:

After having spent too much time trying to get the simple https://github.com/csdvrx/sixel-tmux/ features into mainline tmux (last November https://github.com/tmux/tmux/issues/3753), maybe it'd be easier to jump ship as use zellij?

Could anyone offer recommendations on "riced" zellij configuations, or just a demo where it shows doing with (say charts of disk usage per folder), watching a movie with mpv + keeping a vim to type on?

Well, I now use tmux and tmuxinator. I have had many failed tmux attempts over the years, but I'm firmly bedded in now.

Which leads me to clipboards. Linux has two of them! Adding to the interest, I typically use Neovim remotely, via an SSH connection to a Tmux session. And on my Linux system, I use urxvt as my terminal program. All of these are very UNIX-y tools, and somehow they all need to play nicely together.

The downside of overmind is that it requires tmux, which is a terminal multiplexer tool. If you don't already use tmux, I'd say it's probably not worth learning it just for the purposes of using overmind. But if you're like me and already know/use tmux, this can be a great solution to pursue.
