BTRFS should be stable in the case of power loss. That is to say, it ought to recover to a valid state. I believe the only unstable modes are RAID 5/6.

I’d recommend BTRFS in RAID1 mode over mdadm RAID1 + ext4. You get checksumming and scrubs to detect drive failures and data corruptions. You also have snapshotting, in case you’re prone to the occasional fat-fingered rm -rf.

For backup, maybe a blu-ray drive? I think you would want something that can withstand the salty environment, and maybe resist water. Thing is, even with BDXL discs, you only get a capacity of 100GiB each, so that’s a lot of disks.

What about an offsite backup? Your media library could live ashore (in a server at a friend’s house). You issue commands from your boat to download media, and then sync those files to your boat when it’s done. If you really need to recover from the backup, have your friend clone a disk and mail it to you.

Do you even need a backup? Would data redundancy be enough? Sure if your boat catches fire and sinks, your movies are gone, but that’s probably the least of your problems. If you just want to make sure that the salt and water doesn’t destroy your data, how about:

1. A multi-disk filesystem which can tolerate at least 1 failure
2. Regular utilities scanning for failure. BTRFS scrubs, for example.
3. Backup fresh disks kept in a salt and water resistant container (original sealed packaging), to swap any failing disk, and replicate data from any good drives remaining.
4. Documentation/practice to perform the aforementioned disk replacement, so you’re not googling manpages at sea.

This would probably be cheapest and have the least complexity.

I wouldn’t trust anything like that to the open internet. It would be better to access the system over a VPN when you’re outside the network.

How about writing a script to automate the deletion, thus minimizing the chance of human error being a factor? It could include checks like “Is this a folder with .git contents? Am I being invoked from /home/username/my_dev_workspace?”

In a real aviation design scenario, they want to minimize the bullshit tasks that take up cognitive load on a pilot so they can focus on actually flying. Your ejector seat example would probably be replaced with an automatic ejection system that’s managed by the flight computer.

Yeah, I believe there’s some kind of bridge mode you must enable on the host’s interface.

As others have said, a reverse proxy is what you need.

However I will also mention that another tool called macvlan exists, if you’re using containers like podman or docker. Setting up a macvlan network for your containers will trick your server into thinking that the ports exposed by your services belong to a different machine, thus letting them use the same ports at the same time. As far as your LAN is concerned, a container on a macvlan network has its own IP, independent of the host’s IP.

Macvlan is worth setting up if you plan to expose some of your services outside your local network, or if you want to run a service on a port that your host is already using (eg: you want a container to act as DNS on port 53, but systemd-resolved is already using it on the host).

You can set up port forwarding at your router to the containers that you want to publicly expose, and any other containers will be inaccessible. Meanwhile with just a reverse proxy, someone could try to send requests to any domain behind it, even if you don’t want to expose it.

My network is set up such that:

• Physical host has one IP address that’s only accessible over lan.
• Containerized web services that I don’t want to expose publicly are behind a reverse proxy container that has its own IP on the macvlan.
• Containerized web services that I do want to expose publicly have a separate reverse proxy container, which gets a different IP on the macvlan.
• Router has ports 80 and 443 forwarding only to the IP address for my public proxy

It would have to iterate over all saved keys, which sounds rather inefficient to me and potentially unsafe (timing attacks etc.)

sshd only checks for matches in the user’s authorized_keys file, not system wide.

They would not even need to open source the servers. Just making the server available for users to run (even under a proprietary license) would be enough.

Ooh! Thanks for the tip! Been looking for some affordable drives for my next system.

I bought a LFF Dell Poweredge back in the fall, and have been waiting on a good deal for 3.5" disks. My current machine is a SFF HP Proliant, and I hate how much a 2.5" drive with good capacity costs.

A bridge in America collapsed after a cargo ship crashed into it.

Inscryption is a video game where you play cards against dark and insidious opponents. Outside of the story about your character and their opponents, there’s a super-story about a someone who found a mysterious floppy disk with Inscryption on it, told through video clips.

The point of this campaign is not that it’s trying to stop a “bad business practice”. There’s a strong possibility that this is illegal in many countries. Just because America is a hellscape of terrible consumer protection rights doesn’t mean people in other countries don’t deserve the products they paid for.

Yeah, apparently it’s the wand from a Rancilio Silvia: https://m.youtube.com/watch?v=5AOTa3bEpYM

Everyone’s gotta start somewhere. I do know that it’s not easy for trans men to get a well-fitting suit. I’m familiar with one case where the tailor sent the suit back without any alterations, because they thought the body proportions given by the shop were a mistake. That was rather infuriating to see, but it worked out in the end. I guess what I’m saying is that you should give yourself plenty of time in advance to get your next suit. It may not be the “come back in a week for pickup” that most men are used to.

Hell, I know a cis guy who had to visit 8 different places to find a suit that fit him. He’s a normal looking guy, but the proportions between his hips and waist was somehow an outlier for 99% of the pants he tried on.

Got a secondhand Delonghi Dedica because I had similar concerns over how much I’d use it. Previous owner installed an aftermarket steam wand, which has been a joy.

Overall, it comes and goes in waves for me. Some weeks I pull shots every afternoon, sometimes it sits unused for a month. I enjoy taking some time to step away from the home office and prep coffee, so espresso is nice for that. I’d probably use it even more if we were more of a milk drinking household. I like my steamed milk drinks, but we don’t reliably keep milk in our fridge.

I’m also very lazy about dialing in shots. We like to buy a variety of beans for our morning French press, so the coffee available for espresso might vary week-to-week. I’m not willing to waste coffee dialing in on a 16oz bag of beans that’ll be gone in a few days, so the quality of my espresso suffers. Do most people generally keep one kind of bean around specifically for their espresso?

Reminds me of an early Uni project where we had to operate on data in an array of 5 elements, but because “I didn’t teach it to everyone yet” we couldn’t use loops. It was going to be a tedious amount of copy-paste.

I think I got around it by making a function called “not_loop” that applied a functor argument to each element of the array in serial. Professor forgot to ban that.

I needed to find large directories on disk the other week, and found the tool btdu to be quite useful.

The 2013 Aleksey German adaptation? I believe it.

One of my favorites though. I like how the foreground is not sacrosanct ground that’s reserved to be empty for sake of the camera. Yeah, just throw some sausages and a few peasants right up in the lens.

It could be a firmware update. I noticed on my machine that there was always one update in the discover program that appeared as ready but never got installed.

Turns out I had to manually run fwupdmgr update to install it.

Consider SW Michigan. 2h drive/train to Chicago, proximity to large bodies of water for summer enjoyment, and if you live in a reasonably-sized town they’re probably good at clearing roads when it snows.

Besides, our winters get milder each year. There’s a couple of big snow/ice events, but the trick is to not be on the road while the heavy stuff is coming down. Wait a few hours for it to ease up and for the snow plows to do their thing.
