Love the out of the box thinking though. Really inspirational!

I would totally do that. Only problem is that the third yacht really is my favourite, so I’m gonna pass if that’s okay. Thanks!

… and enhanced by a sentence or two why it is worthwhile. Getting really tired of the no-effort link drops around here. Better yet, the same no-effort link drop to multiple similar communities on various instances.
Is there a block function for link-only posts?
Are there filters to prevent seeing duplicate content?

Right, thanks.
- Comment on Authentication for external sevices 1 month ago:
“authentication is not security,” can you elaborate on that?
Your statement doesn’t really overlap with my understanding of security, as “just access” seems critically relevant to how secure user data is, for example. Am I missing something?
- Comment on SMTP provider 1 month ago:
EU servers might be worth something to some people, depending on where they are in the world. And while 190% is indeed way more expensive, relatively speaking, it’s still “well under” your goal of EUR 2 per month.

I’ve read good things about migadu. Haven’t used it myself.
- Comment on help needed to understand this diagram of a water flow sensor (from a boiler) 2 months ago:
Good job troubleshooting.
- Comment on help needed to understand this diagram of a water flow sensor (from a boiler) 2 months ago:
5V or 4.68V input isn’t meaningful. The sensor has some input range and 4.68V most definitely falls into that. Could be a design choice that has no real implications.
On the other hand, if the device normally supplies 5V, just yours doesn’t, then that’s further evidence you have a faulty controller.
- Comment on help needed to understand this diagram of a water flow sensor (from a boiler) 2 months ago:
My money is on faulty controller at this point, but I think you’ll need to find someone with electronics chops if you want to avoid just buying parts until it works again.
For what it’s worth, I didn’t mean take the sensor out of the wall, but just electrically unplug it from the controller to see what it does on its own when you turn on the water.
- Comment on help needed to understand this diagram of a water flow sensor (from a boiler) 2 months ago:
Oh and be careful if you do end up trying it.
There’s no safety risk in what I described, but reversing the power supply might very well fry the device.
- Comment on help needed to understand this diagram of a water flow sensor (from a boiler) 2 months ago:
With better tools, it would be easier to troubleshoot more precisely. An oscilloscope would help you understand what’s going on, for example.
From what you describe, I’m actually starting to suspect the other end (the controller?) to be the problem.
One idea you could try before buying anything is to disconnect the sensor, supply it with 5V and ground (double check with data sheet!) and see what’s happening on the output when there is flow. If you don’t measure anything, as I would expect since the pin alternates between a floating state and ground, you then add a 10k or 50k ohms pullup resistor between 5v and output and measure again, and should get the levels you expected to see in the first place.
Don’t know if you’re comfortable doing this, but maybe you can find somebody to help you out?
- Comment on help needed to understand this diagram of a water flow sensor (from a boiler) 2 months ago:
Read your post again, and your readings are of course not in line with what I laid out. Are you measuring the sensor in-system?
If you are, the sensor might indeed be faulty. If you aren’t, you probably need a pullup resistor on the output pin.
- Comment on help needed to understand this diagram of a water flow sensor (from a boiler) 2 months ago:
These flow sensors are usually hall effect sensors, with two or four magnets attached to a rotor with a little water wheel. When water flows, the magnets turn and creates somewhat of a PWM signal at the output (actually it’s high level when magnet is there and low level when magnet is not there or vice versa). Measuring the pin with a slow multimeter, this would indeed give you approximately half the supply voltage when water is flowing, depending on a few other factors. So- readings sound sensible to me. To note that if the rotor stops with a magnet close to the hall effect sensor, you will read 5V (or VCC) at the output, but always VCC/2 when flowing.
Most of these sensors employ an open collector output stage, but that doesn’t need to bother you with the readings you’re getting, I think.
- Comment on Self-Hosted setup for remote music lessons? 2 months ago:
No harm in giving it a try, but I personally wouldn’t bother with a selfhosted solution for it. Especially if you’re not sure it will work out.

Well, paint me green and call me a pickle. More power to you if it works. 😊
- Comment on Self-Hosted setup for remote music lessons? 2 months ago:
Tangent, unsolicited:
Music lessons over video call, that has to be a real pain. I can’t find it now, but there’s an Adam Neely video where he talks about why online recording sessions can’t work, as transmission latency works against the immediacy needed to play music together. He said it better than I can.
Except if your idea is to play in turns, but then capturing the thing you want to show… Can’t you find another teacher closer to you?
- Comment on Please help me stop my baby from crying because kodi keeps buffering 2 months ago:
Installing the Jellyfin add on into kodi takes a few minutes. Nothing much to consider, just try it and see if that changes anything.
I have a similar setup (rpi with OSMC, media hosted on file server) and prefer using Jellyfin as the source for all clients, as it keeps track of watched status across everything. It’s not perfect, but better.

- Comment on New Network Stack with unknown issues.. 3 months ago:
Good opsec not to share your WiFi ssid, by the way. I can’t find one right now, but I’ve seen global “wardriving” maps of all broadcast WiFi ssids even with history over time that allows to pinpoint a somewhat unique ssid on a map. A list of ssids around you pretty much gives away your precise location.

Had similar behaviour last night. Turned out UnboundDNS had crashed in my opnsense firewall and took “internet connectivity” with it. Restarting the service fixed it in one click after I found it.
- Comment on Design patterns 4 months ago:
It’s not my Github, but I think you’d do something like print and store in a safe place your trusted party has access to. My SO has my Keepass password stored in their password safe and theoretically knows (and hopefully will recall when the need arises) how to find my Keepass file, for example.
In short, it’s trust. And then there’s the fact that they would never voluntarily touch this stuff anyway. 😅

Storage box is self-serviced storage on a single server, as far as I’m aware. If you need replication, you need to rent storage at a second location and do it yourself.

I can see what you mean, too, but am still on the liking him side I guess. And anyway, l’art pour l’art and all that, right? 😅
- Comment on Welcome to the Age of Technofeudalism - The tech giants have overthrown capitalism 6 months ago:
Hm, interesting. I didn’t read it like that, but as an economist trying to make sense of what’s going on and explain it to others. I didn’t question whether the thoughts are original, neither do I know if there are holes in his concepts that I as a non-economist am blind to. My personal opinion, anyway, is that the message is important today (or better yet 15 years ago but nobody would have listened 😉), no matter whether he is primarily motivated by his ego or what.
Maybe this makes me part of the people he caters to, but that line of thinking doesn’t lead anywhere meaningful anyway, I think.
I liked the end of the book: A call to action for us to come up with tools and technological solutions for “users” to stand together so we can create resistance against overly powerful cooperations and demand our rights. I don’t think it’s hypocritical for him to ask for this either. We need people to point problems out and problem solvers, both.
Have you read more of what he wrote or how did you come by that opinion on him? Technofeudalism and a number of interviews leading up to the book release was the first I was exposed to him.
