{Ref,Unsafe,Once,}Cell is one of the more confusing parts for me in Rust and I almost never end up using them because I don't really know what they are good at.

Also, have to admit that the use of Arc is rare and the use of Rc is never.

8️⃣ Here's the 8th post highlighting key new features of the upcoming v257 release of systemd.

A longer time ago systemd introduced JSON based user records as an extension of classic UNIX `struct passwd`. These records can be provided via Varlink IPC or via drop-in files. The much richer set of account settings is documented here:

@lari Sillä näyttäisi olevan samanlaiset Eccon kengät kuin mulla. En voinut olla spottaamatta :-)

OK, good because I've been wondering this sometimes.

I also wonder if customer service knows this:

1. https://amazonforum.my.site.com/s/question/0D56Q0000DFHPH0SQP/audiobook-no-longer-running-in-kindle-app
2. https://uk.amazonforum.com/s/question/0D56Q0000B7awIkSQI/unable-to-download-audiobook-title-on-kindle-paperwhite-and-kindle-app

Bunch of hits can be found where it is not clearly stated that "no it does not and will not work on the Kindle device." At most you have to be able to read it in-between the lines. I had my first Kindle device in 2010 or 2011 and I have faint memory that it could at least text-to-speech books but have not been able to find that option either in my current Kindle...

@lkundrak @oleksandr there is Windows version of mc but with FMs i prefer ”designed for OS” because RW of files is sensitive and corner case mined activity.

My recommended list of crates for baremetal, firmware and no_std alike programming:

- https://github.com/rcore-os/buddy_system_allocator
- https://github.com/Lokathor/tinyvec
- https://github.com/google/zerocopy/
- https://github.com/rust-embedded/heapless
- https://github.com/KokaKiwi/rust-hex
- https://github.com/de-vri-es/serial2-rs
- https://github.com/m4b/goblin
- https://github.com/gimli-rs/gimli

This is a list of crates, which I've actually used and found them useful over time. I've not done kernel code (yet) in Rus. Instead I've worked on two bytecode (with JIT) hosts, i.e. Enarx (wasm) and now with PolkaVM (previously wasm but I'm working on riscv32emac derivative which is the next generation). And right, I'm implemented a crate for zmodem (see zmodem2) ;-)

The crate that I'm not yet sure because have not been able to do yet stuff that I'd want to do with it is:

https://github.com/rust-vmm/vm-memory

I.e. use it for special mapping but with no VMM involved (my uses cases actually involve both with and without VM containers). So looking into that over time. E.g. Paolo is involved with this so I expect it to be quality, and rather contribute than look for other option.

So... cannot really blame SUSE :D And I'm still open for getting bugzilla access :---)

Has anyone bought one of those beautiful Checkmate displays? I'm planning to buy one to accompany my MiSTeR FPGA (and Atari STE with Ultrasatan \,,/ :666)

Not only SUSE problem tho. Red Hat has like 3-4 different types of accounts. I don't get this. Fucking horror to create any account for any distribution.

Optimally there would only one account ever. Even like if you are employee at some point it could be just a cap of some sort... Even that does not require a separate account. OK maybe 2x (community and "enterprise" for employees).
