Without any expertise, I’m going to say that minuscule amounts of radioactive nickel from your CR2032 replacements compared to wasted lithium on pretty much every battery your all current devices have plus single use LiIon-cells on e-cigs, single use toys and whatever is a pretty good improvement. In 100 years or so all that nickel is converted to copper with small amounts of radiation and heat as byproducts, in today’s technology, is pretty good.

And the radiation is beta-negative. I’m not an nuclear physicist, but if I’m not mistaken your common 3032 cell has enough metal to shield pretty much all of the radiation. Just don’t eat them and maybe stick with li-ion on your wrist watch.

Fair point, but basic physics has been a part of our education program for at least 60 years. Also for few years the ‘exchange priced’ or ‘market valued’ electricity has been somewhat popular and on the news, which adds up to the general understanding as if you know your stuff it means quite literal money as your bills are smaller. So, maybe ‘absolutely everyone’ is a bit of a stretch, but in general the majority of adult people understand the concept.

And also a ton of common folk understand it at least a bit on a deeper level as basic physics is included to studies beyond elementary school regardless on what you study. Sure, not everyone understands (or cares) how 3 phase AC in here adds up to 400V or why you need to have 2,5mm² wires for 16A fuse, but it’s still pretty common that people, specially in a separate house, understand how you can only pull 2300W out of a 10A circuit or 3600W from a 16A one (10 and 16A being the most common fuses in a household in here).

I’ve been a happy customer with joker.com (Germany) for at least 10 years.

I think it’s easier the other way round, find all symlinks and grep the directory you want to move from results.

Something like ‘find /home/user -type -l -exec ls -l {} ; | grep yourdirectory’ and work from there. I don’t think there’s an easy way to list which symlinks point to any actual file.

Exactly. You can build rules with ufw and view them on iptables. Maybe the one thing ufw does better out of the box is persistent rules and simpler “firewall on/off” switch, but specially on this particular question I don’t think they matter.

And me.

They are excactly what the name implies. Testing is generally pretty good, but it’s still testing. And unstable is also what the name implies. People, myself included back in the day, run both as daily drivers, but if you want rock stable distribution installing unstable revision might not be the best choise.

Debian. I’ve had installations which went trough several major version upgrades, I’ve worked with ‘set and forget’ setups where someone originally installed Debian and I get my hands on it 3-5 years later to upgrade it and it just works. Sure, it might not be as fancy as some alternatives and some things may need manual tweaking here and there, but the thing just works and even on rare occasion something breaks you’ll still have options to fix it assuming you’re comfortable with plain old terminal.

1. VM running on a proxmox host. Tips: make sure you know your backups are in a state you can restore data from them.
2. Nightly backup via proxmox to Hetzner Storage box with 2 day retention. I’d like a local copy too but I don’t currently have hardware for it.
3. Don’t know. Personally I have a DNAT rule on firewall and my instance is directly open to the internet. You might not want that and I might not recommend it, but right now, for me, it works. I’d need to look in a VPN solution for android I could replace the current ‘open for all’ situation.

Actual shortage. Performance drops significantly when zfs doesn’t have enough memory. It might have been an option to tweak configuration for zfs pools, add SSD for caching and so on, but I needed to change drive configurations anyways for other reasons so for me it was easier to drop zfs and switch to software raid.

How much RAM your system has? Zfs is pretty hungry for memory and if you don’t have enough it’ll have quite significant impact on performance. My proxmox had 7x4TB drives on zfs pool and with 32 gigs of RAM there was practically nothing left for the VMs under heavy i/o load.

I switched the whole setup to software raid, but it’s not offically supported by proxmox and thus managing it is not quite trivial.

Advertisers, stock prices, inverstors and other stuff like that. As in “losing money”.

I mostly use battlestar galactica ship names for my own hardware, but it’s been mixed with boring ‘<function>.mydomain.foo’ names as well. I should rename a bunch of stuff around and include them in my DNS.

The exchanged mails between the IMAP host and the MTA need a unique identifier to organize contents of the DB, and this would not be possible or automatic if your switched the upstream MTA.

It sure is possible. I’ve copied maildirs over different software, different servers, local copies back to the server and so on. Also if you just rely on your own IMAP server the upstream doesn’t matter as fetchmail (or whatever you choose to use) anyways communicates between hosts on their preferred protocols.

Obviously there’s a tradeoff since now you’re responsible for your backups and maintaining your server, but it can sit nicely on your private LAN with access only locally or via VPN without direct access to the internet. And you don’t need MTA to run IMAP server in the first place.

You can run a dovecot (or any IMAP server) where ever you want and use fetchmail to pull data from POP-server into it. There’s plenty of discussion and instructions around the web so I won’t copy’n’paste them here, search for ‘fetchmail dovecot’ or something similar.

Can you switch to console? Try ctrl+alt+F2 when the system is booted up and log in to that.

I suppose some package update was interrupted or crashed. You can attempt to re-run what’s missing with ‘sudo apt-get install’ and ‘sudo dpkg-reconfigure -a’. And, assuming your console access works, you can at least check log files on what’s wrong, but for that I don’t think any generic ‘read /var/log/syslog’ file is too helpful as there’s a ton of stuff and with things like journalctl it’s pretty difficult to navigate around if you don’t know what you’re looking for.

And also, more details would be helpful. What you mean by ‘enters a loop’, what it actually says that went wrong and so on.

Dammit, my organic memory failed yet again. It’s been a while since I’ve seen that prompt (and I have agreed to that as well at least few times).

Does anyone sell ‘Yes, Do As I Say!’ stickers?

You could possibly recover from that on console, just install few metapackages. And have backups.

I meant that the technology itself is reliable. And you can do self hosting just fine too, I’ve been doing it since 2010 or so, but running a local smarthost which sends messages via reputable SMTP provider works just fine too. Or even directly interacting with the SMTP provider from all the applications you’re running.
