I do it. Postfix+dovecot+spamassassin managed with ISPConfig running on a VPS. Works just fine, but my domains already have a long-ish good reputation so that may play a part on my experience. Biggest headache is to keep things running, which occasionally means jumping trough hoops microsoft(mostly) and others throw at you by flagging your server as spam for no apparent reason.

It’s quite likely that any given IP, unless you get one from shady VPS provider or something, is “clean”. And if it’s not it’s usually not that big of a deal to get it cleared from major blacklists (spamhaus, google and microsoft covers quite a lot). You just need to dig up proper forms to tell them that you’re a new owner of said IP and promise to play nice.

Same goes with domain names, but if you get a new one that’s a non-issue. Just set up SPF-records properly (and preferably DKIM/DMARC, but those aren’t strictly necessary and need a bit more than a single TXT-record) and you’re good to go.

And then you of course need to stay away from those lists. If you configure your SMTP to act as a open proxy you’ll be on every shitlist on the planet pretty quickly. So, reasonable measures against compromised account (passwords, firewalls, rate limits…) and against other threats (misconfigured/unsafe web service used for spam and stuff like that). Any of those alone are not too difficult to accomplish, but there’s quite a few things you need to get right.

Maybe easier to get anything runnin quickly. But it obfuscates a lot of things and creates additional layer of stuff which you need to then manage. Like few days ago there was discussion about how docker, by default, creates rules which bypass the “normal” INPUT rules on many (most?) implementations. And backup scenario is different, it’s not as straightforward to change configuration than with traditional daemon and it’s even more likely to accidentally delete your data as a whole.

As I already said, docker has its uses, but when you’re messing around and learning a new system you first need to learn how to manage the ropes with docker and only after that you can mess around with the actual thing you’re interested of. And also what I personally don’t really like is the mindset that you can just throw something on a docker and leave it running without any concern which is often promoted with ‘quickstart’-type documentation.

You absolutely can run services without containers and when learning and trying things out I’d say it’s even preferable. Docker is a whole another beast to manage and has a learning curve of it’s own.

Containers can of course be useful but setting everything up, configuring networking, managing possible integrations with other components (for example authentication via LDAP) it’s often simpler just to run the thing “in traditional way”. With radicale you can just ‘apt install radicale’ (or whatever you’re using) and have a go with it without extra layer of stuff you need to learn before getting something out of the thing. And even on production setups it might be preferred approach to go with ‘bare metal’, but that depends on quite a few variables.

On residential connections it’s a bit pain in the rear, but if you get VPS (or something similar) it’s perfectly manageable. You just need to maintain stuff properly, like having proper DNS records, and occasionally clear false positives from spam lists. The bigger issue is to have proper backups and precautions, I’ve hosted my own emails for over 10 years and should I lose all the data and ability to receive new messages it would be a massive personal problem.

Obviously we’re talking about hobbyist level stuff and with that there’s always something what can go wrong and it’s not always obvious what it is. So if the ‘remote end’ doesn’t have someone who can do at least very basic troubleshooting it can be nearly impossible to fix the setup over the phone unless you just replace the whole thing and ship whole units back and forth.

But in this particular case the remote end has someone who knows their stuff so it’s taken care of, with or without a KVM. I’ve been thinking a similar setup with my relatives and on my case the distance isn’t an issue but it’s still something I’d need to bother family members with and, for me, it was simpler to get a storage box from hetzner and run backups to that instead of getting more hardware.

Maintenance is anyways something you need to consider and viable options for that vary on a case-by-case basis, so there’s no ‘one size fits all’ solution.

It won’t help if your power supply breaks and KVM itself can malfunction too. It’s of course nice to have, but it has limitations.

I would consider also the case where something goes wrong. Maybe the whole thing crashes, maybe you misconfigure something, maybe there’s a power outage or something else happens and you lose the connectivity. Is there someone on site who can do anything to your hardware as you can’t easily just go and figure it out by yourself?

If the answer is ‘no’ then I would strongy reconsider the whole approach. On a worst case scenario the system goes down before you’re even back home from the trip and then your hardware is just gathering dust.

I somewhat agree on your comment about documentation and UI (altough once you get used to it, it’s manageable) but just to add with my experience on these things: for me they’ve been rock solid. I’ve used them both at home and professionally (mostly on small-ish networks) for at least 10 years and they just seem to run just fine.

Currently my home router is RB4011iGS+ and there’s been absolutely no problems with it in the 4-5 years it’s been on my network. I’m not saying all their models are as reliable and there’s not that many models I’ve had my hands on, but my experience with them has so far been pretty good.

You’ll get used to it eventually

I’ve been earning my living mostly with connecting to remote systems via ssh (and other means) for quite a few years and I still occasionally mess up and enter commands on a wrong terminal. Less now than I used to, but it still happens. The trick is to learn youself to pause for a second and confirm the target for any potentially destructive or otherwise harmful command, no matter if it’s locally or to some server other side of the world.

Do they really care enough to check your info manually if you don’t use your domain name for malicious purposes?

Depends on TLD how strict the checks are, but generally you’re at least violating TOS by doing it and can lose your domain should someone actually check the info. A lot of registrars provide at least whois-security, so they’ll know your real details but won’t share them openly to anyone who asks. I assume if you get into something illegal and court orders to release the data then they’ll happily comply instead of hurting their own business.

But if you just want to keep your real name and address out of the internet, that would be enough at least for me.

Bare feet are a bit clickbaity on the headline. That alone doesn’t mean much, but when it happens on a area where you should have full protective gear at the (supposed to be) sterile part of the manufacturing it’s of course a big deal. But it would be equally big deal if you just stroll there in your jeans and t-shirt with boots you stepped on a dog shit on your way to work. And even then it’s not even close of being the biggest issue on manufacturing where they constantly ignored all of the safety protocols, including ignoring test results which told them that the product is faulty.

Almost any kind of grease will work. Moisturising cream, oil, butter, engine oil and so on. It’ll soften the glue and whatever residue your chemical leaves behind can be wiped off with hand sanitizer or a drop of soap. The trick, as you mention, is to use way less than what you think you’ll need to avoid mess.

The ones I have go trough the onboard voltage regulator and you can use them to power USB-devices. I suppose they’ve skipped diodes and other protective components so it can feed back to the circuit, but I haven’t tested that.

In EU no one individual needs to sue them. The what-ever-the-office-might-be-responsible at EU burecracy will just send them an nicely worded letter that says “play by the book or we’ll give you fine big enough to bankrupt you no matter how much money you think you have”. The fine is based on company revenue (or sales, I don’t remember what it spesifically was) and there’s no way you’ll weasel yourself out of that no matter how many american lawyers you can hire. The same folks forced Apple to adapt usb-c, so good luck Spez if you try to challenge that.

Is French just the most commonly spoken common language, even in Germany and Czechia?

Not at the slightest. I suppose it’s just a marketing thing where french sounding names are supposed to be more appealing or tell something about the food or atmosphere at the hotel. And based on a very quick visit at booking.com I don’t see any french sounding hotels at Berlin, so I don’t know how many there actually are. I’m sure there’s some around like everywhere in the world, but I think majority is something else.

And there’s a lot of shared history between countries, so that can mix things up in various ways.

Same in Finland as well. I have both automatic and manual cars, newer ones are often automatic and it’s a bit funny that more often people aren’t famliar with automatic transmission and they need to be spesifically told to keep their left foot at the floor and not do anything with it.
