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.

The man is a monster. I don’t know how many of my build jobs have been murdered by this fiend.

I use a fuckload of soap and hope it keeps the grease from re-forming. Is that still bad?

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

Did you mean source-available?

I guess? Always thought there was some pedantic Stallman-esque argument for the differentiation between FOSS and OSS, independent of the Open Source vs Source Available distinction.

Not sure if you’re able to edit the title, but this doesn’t look like FOSS, just open source.

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.

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

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.

Reverts work because users have equal write access to all the data. You can mess things up in the codebase, and even if you die of a heart attack 10m later, my revert is just as valid as your commit.

It’s not really the same when every user has “sovereignty” over their address in the ledger. A bad actor has to consent to pushing a revert transaction onto the chain, or they have to consent to using a blockchain system where 3rd-party reversion is possible (which exists on some systems, but also defeats the concept of true sovereignty over your address).

I know that your question is about tasting basics, and I think the answers here will get you on the right path.

There’s a lot that goes into coffee tasting on the advanced end. Ever wonder who decides that a coffee tastes like “raspberry” and “chocolate”? A few years ago, I found a local roaster that runs barista classes, and I got tickets to their coffee tasting session. It’s really interesting to learn about all the process and procedure that goes in to tasting coffee. They take something as subjective as taste and turn it into (somewhat) objective and quantifiable data. I also learned how coffee beans are graded, and how roasters source their beans.

The official term for this process is “cupping”, so if you’re interested, look in your area for cupping classes. I had a great time!

My parents drink mediocre pre-ground coffee. I left a single-cup French press at their house so I can have better tasting coffee whenever I visit. It doesn’t require advanced prep like cold brew.

False gods can eat plutonium.

What are people’s thoughts about the children’s size urinal? Never use it if there’s another option? Only use it if the other option would place you adjacent to another person? What about if you have a choice between adult and child’s urinals next to each other, but using the child’s urinal would allow space for another person to optimally avoid neighboring persons?

I feel like this is a variant of the trolley problem that’s woefully unexplored.
