Hello! I'm Daniel.

I love free/libre software, run Linux or BSD on every computer I get my hands on, and think a good book paired with a cup of coffee is a little piece of Heaven.

Last night I finished "The Rise of Endymion" by Dan Simmons... the final book in his "Hyperion Cantos".
Its incredible (even if I didn't like the very last bit). A vision of a possible future for humanity in space the likes of which I've never read anywhere else. Even a future Dalai Lama is a character! Buddhism is a strong element in the book and the ideas it raises are so intriguing that I just picked up "Buddhism: A Journey Through History" by Donald S. Lopez Jr.

I explored the immutable Bluefin Linux on my mini pc for a week. Very solid project!
Even more so than a Linux aimed at developers, I could see it being a great *first* Linux for someone with the pre-installed Flatpak software centre, automatic updates, atomic read-only system images, and rollbacks if things go wonky.
But I'll be putting Chimera back on the box. I guess I'm just a mutable "read-write" kind of guy. 🙂

Chimera Linux does things differently: the distro is built from scratch, musl instead of glibc, init is dinit, FreeBSD userland, ...
Fresh install on my Thinkpad using OpenZFS and ZFSBootMenu. Curious to explore further. I'm thinking of a setup where Chimera is my desktop and FreeBSD on a home server.

@nprofile…d0wl First attempt proved too ambitious for this Gentoo newbie: Encrypted root + BTRFS + systemd + Limine bootloader. Upon reboot got as far as the Limine boot menu then... boom.
Second attempt I tried a few different things and swapped out Limine for GRUB, reboot, and ended up in the emergency shell.
Third attempt I went with bog standard defaults: no encryption + OpenRC + GRUB.

I think Chimera Linux is an intriguing mix of components: Linux kernel, FreeBSD userland, apk package manager, (non-systemd) dinit. I checked it out briefly last year. Now I want to take a second, closer look.
Installed Chimera Linux with Root-on-ZFS with ZFS native encryption and ZFSBootMenu as bootloader on a VM. Time to explore!

For ages I used `bash` simply because its the default shell on most Linux distributions. Now that I'm exploring FreeBSD I thought to myself, why not also consider alternative shells?
I briefly used the FreeBSD default `sh`, then spent a few weeks with `oksh` (portable version of OpenBSD `ksh`). Inspired by @nprofile…6m2n 's "Reasons I still love the fish shell" I decided to give the aforementioned shell I try... 🐟

My first time trying to upgrade FreeBSD. Everything seemed OK but upon reboot no longer have working graphic card support:

Quick preliminary search leads me to think I might need to build some packages from ports (another first).

A CanSat is a simulated satellite design where all its major components (power, communications, payload) are designed to fit within the volume and shape of a regular pop can. Being inexpensive to build and something that can be taken from design to launch (into the air) in less than a year, it has a particular appeal to students (and me!) to try their hand at hacking on space technology. There are various CanSat competitions around the world:

@nprofile…vcky I loved "Starship and the Canoe". I'm going to give it a re-read in March.

An open-source hardware and software project for the amateur astronomy community, PiFinder is a Raspberry Pi-based all-in-one device that mounts on a telescope and combines positioning, search, chart display, and logging to help observers find and view astronomical objects. Use the online build guide to source components and build your own PiFinder, or purchase a kit or assembled unit:

@nprofile…mgtx I'm going to give BTRFS a second, closer look!
Three questions:
1. Do you also encrypt /boot?
2. Do you use the snapshots feature?
3. Do you use GRUB as your bootloader, or something else?

Which file system should I use for an encrypted root partition on Linux for a single disk?
I typically use LUKS + ext4.
I've also used encrypted BTRFS and ZFS (with ZFSBootMenu) but never worked with them to any extent beyond getting them setup. I see distros such as Fedora are now defaulting to using BTRFS.
For a Linux install on systems with 8GB-16GB RAM and a single disk (no RAID), I'm seeking some advice: Should I stick with ext4? Or use BTRFS? Or ZFS?

@npub15zu…s7lx Your articles and especially "Rebel Code" introduced me to Linux and this whole idea of Libre/Open Source. Thanks for providing the new book as a downloadable DRM-free epub. Looking forward to reading!

Ventoy can boot not just Linux but FreeBSD installation images too. Nice!
I just discovered this while making my first ever FreeBSD install. :freebsd: 🙂

@npub13w6…479m How so? Is it now how APOD describes it ... a time-lapse video composed of images taken from a fast-moving (Cassini) spacecraft?
