    Today in it's ZFS. It gives me

    • all in one volume management (no volume-groups and logical volumes and manually resizing partitions on those logical volumes with a dozen different commands, no playing the "oof, need more space on partition A and have too much free space on partition B, back up all the files, nuke both, shuffle partition-sizes/locations, restore the files" dance)

    • transparent file compression

    • transparent volume encryption

    • fast and effectively free snapshots and clones (you start paying the cost if they diverge or deleting files that remain in a snapshot, but that's to be expected)

    • same-disk redundancy with copies=2 to help prevent against bitrot, and multi-disk redundancy with effectively zero effort

    • the CoW means no need for fsck(8) horribly slowing my boots or finding orphaned fragments of files and shunting them into a lost+found/ directory (my biggest frustration with OpenBSD's FFS2) in the event of an abrupt power loss

    • efficient send/receive (beats rsync hands down in terms of speed)

    • fine-grained quota/reservation control

    • utilities make scripting easy with output-formatting options

    • cross-OS support in a way that very few other filesystems provide (other than FAT 😆)

    I'm sure there are additional reasons that didn't percolate to the top of my brain, but it's just so much more pleasant than any other disk management I've done on any OS.

    Today in #FreeSoftwareAdvent, I want to appreciate OfflineIMAP/mbsync. Both have served me well for bringing a remote IMAP mailbox locally and keeping it in sync across multiple machines, allowing me to mow through mail even when offline, and then have reasonable confidence that everything will just sync back up when I go online again.

    Today's follow-up #FreeSoftwareAdvent entry is vi/vim.Which I use depends on the situation. Classic vi/nvi tends to be lighter weight and start faster, while vim offers extra features that I find particularly useful). I usually just type `vi` which gets me `vi` on OpenBSD, `nvi` on FreeBSD, and `vim` (or `vim-tiny`) on most flavors of Linux. If I specifically want vim features, I'll invoke it as such directly.I could go on for ages about favorite features, but a select few:• the ability to keep my hands on the home row and not use a mouse is helpful for preventing RSI symptoms• it's a language¹ of editing, involving counts, verbs/commands, and objects/motions, so I can express my editing *intent* and then use the period command to re-issue that same editing *intent*• the :global or :substitute commands can make massive-yet-precise edits across huge files• the :*do commands extend that power across multiple files, allowing me to precisely edit millions of lines across thousands of files with targeted precision• it's ubiquitous—even as some Linux distros have started removing ed(1) from the base installs , relegating it to packages, I can always type `vi` on any Unix-like/POSIX system and be editing with a powerful editor. And with builds for Windows and my phone, I can use it everywhere. No need to install anything• they work just fine over a SSH connection without a GUI, and use minimal resources so they work even on that old hardware from the 90s.⸻¹ https://gist.github.com/nifl/1178878

    Today it's awk(1)I use it almost daily—from simple column-extraction (specifying column separators and mashing together various columns feels easier with awk than with sort(1)), to summing and running totals, to aggregating counts of data, to reformatting text, etc…so many little uses pop up.It's available on every POSIX platform making it easy to write cross-platform utilities without having to install additional run-times like Python/Ruby/Node and the heavy dependencies that come with them.I've even written cgi-bin/ scripts in awk, allowing dynamic data processing on my stock OpenBSD systems with httpd+SlowCGI without non-stock software in the chroot.https://blog.thechases.com/categories/awk/#FreeSoftwareAdvent

    Kicking off #FreeSoftwareAdvent (thanks, @neil), I'll open with remind(1)While it took several articles and a couple attempts before I switched over to using it, once you taste the power of what it can do, it's hard to go back to less-capable calendaring tools.While the classic "garbage day is on Thursday unless there was a holiday earlier in the week, in which case it moves back to Friday" scenario is a nice little demo of its power, one of the best examples from my daily use is the kids' school calendars:• the teen has an A/B schedule which doesn't mesh nicely with calendar days, week-days, etc• similarly, our elementary-age kiddo has a 4-day cycle schedule for her "specials" classBut remind's nonomitted() function makes quick work of both of those, taking into consideration weekends, the school holidays, and using PUSH/POP directives for high-school testing days that impact his A/B schedule but not her 4-day cycle. I've never encountered another calendar that handled all the edge-cases with so little effort.It's a little rocky interchanging with other calendars (you have to use rem2ics to create .ics files to share, and pulling in others' iCal is non-trivial and doesn't seem to maintain the fidelity of remote events).But otherwise, this runs a great deal of my life schedule.
