Well you must have either set up a port redirect (ipv4) or opened the port for external traffic (ipv6) yourself. It is not reachable by default as home routers put a NAT between the internet and your devices, or in the case of ipv6 they block any requests. So (unless you have a very exotic and unsafe router) just uhhh don’t 😅 To serve websites it is enough to open 443 for https, and possibly 80 for http if you want to serve an automatic redirect to https.

That’s odd, I upgraded my ender 3 with bed leveling and removed the knobs to mount it fixed, because the damn knobs keep moving and then you have to redo the bed calibration. To be honest I can imagine one reason might be that a loosely mounted bed gives you more fault tolerance against the nozzle being too low. I put my bed on two parallel linear rollers for more rigidity, and combined with dual z screws the nozzle has no chance anymore to produce any sort of first layer when it is slightly too low. That made me realize just how much the stock ender 3 is flopping around, but also how this can give you mostly okayish results most of the time without having to deal with a ton of small tolerances.

A colleague of mine had a (non externally reachable) raspberry pi with default credentials being hijacked for a botnet by a infected windows computer in the home network. I guess you’ll always have people come over with their devices you do not know the security condition of. So I’ve started to consider the home network insecure too, and one of the things I want to set up is an internal ssh honeypot with notifications, so that I get informed about devices trying to hijack others. So for this purpose that tool seems a possibilty, hopefully it is possible to set up some monitoring and notification via uptime kuma.

You do not want Octoprint on a machine that is busy. Otherwise you have load spikes that cause Octoprint to not be able to send the move-commands (gcode) as fast as the printer executes the movements. This problem is pronounced with faster printers and slicers that break up arcs into small straight lines (which is practically all slicers). Otherwise your printer stutters because it has to take small breaks to wait for the next command from octoprint.

What privacy concerns do you have? I’m all for privacy, but I don’t really see where registrars are a delicate topic in that. The most that comes to mind is that some (most?) have a service where they do not give out your name and address for whois requests, but instead the details of the registrar (namecheap has that for example).

True words. The sustained effort to keep something in decent shape over years is not to be underestimated. Now when life changes and one is not able or willing anymore to invest that amount of time, ill-timed issues can become quite the burden. At one point I decided to cut down on that by doing a better founded setup, that does backup with easy rollback automatically, and updates semi-automatically. I rely on my server(s), and all from having this idea to having it decently implemented took me a number of months. Just because time for such activities is limited, and getting a complex and intertwined system like this reliably and fault tolerant automated and monitored is simply something else than spinning up a one off service

And they believe all employees actually remember so many wildly different and long passwords, and change them regularly to wildly different ones? All this leads to is a single password that barely makes it over the minimum requirements, and a suffix for the stage (like 1 for boot, 2 for bitlocker etc), and then another suffix for the month they changed it. All of that then on sticky notes on the screen.

Since you run everything in docker, I guess you have experienced the benefits of containerization. So why not leverage that for your host too?

Fedora IoT is a container-based host that runs on your hardware, with a focus on edge device deployment.

https://fedoraproject.org/iot/ I have it running on two servers as well, and it works great. The only thing I changed is that I layered docker on it instead of using podman, because at the time I had trouble getting my reverse proxy working properly over ipv6

Those are symptoms of sitting at that operation point permanently, and they are a of course a concern. What I’m after is that people think that energy gets put in to the battery, i.e. it gets charged, as long as a “charger” is connected to the device (hence terms like “overcharged”). But that is not true, because what is commonly referred to as “charger” is no charger. It is just a power supply and has literally zero say in if, how and when the battery gets charged. It only gets charged if the charge controller in the device decides to do that now, and if the protection circuit allows it. And that is designed to only happen if the battery is not full. When it is full, nothing more happens, no currents flow in+out of the battery anymore. There’s no damage due to being charged all the time, because no device keeps on pumping energy into the cell if it is full.

There is however damage from sitting (!) at 100% charge with medium to high heat. That happens indipendently from a power supply being connected to the device or not. You can just as well damage your cells by charging them to 100% and storing them in a warm place while topping them of once in a while. This is why you want to have them at lower room temperature and at ~60%, no matter if a device/“charger” is connected or not.

(Of course keeping a battery at 60% all the time defeats the purpose of the battery. So just try to keep it cool, charged to >20% and <80% most of the time, and you’re fine)

“overcharging” doesn’t exist. There are two circuits preventing the battery from being charged beyond 100%: the usual battery controller, and normally another protection circuit in the battery cell. Sitting at 100% and being warm all the time is enough for a significant hit on the cell’s longetivity though. An easy measure that is possible on many laptops (like thinkpads) is to set a threshold where to stop charging at. Ideal for longetivity is around 60%. Also ensure good cooling.

Sorry for being pedantic, but as an electricial engineer it annoys me that there’s more wrong information about li-po/-ion batteries, chargers and even usb wall warts and usb power delivery than there’s correct information.

It is not that easy to understand what you want, to me it reads like you want something like Nextcloud - i.e. your own little cloud, where you can put all your stuff, and view it through the webbrowser or the nextcloud apps, and also keep selected parts of your stuff in sync with your devices (or automatically upload photos take with your smartphone for example).

Backup of Nextcloud (or whatever you want to use) is a seperate topic. Any incremental backup tool would apply though, so there’s much to choose from. I personally use btrbk which uses Btrfs Send+Receive to push incremental snapshots to an offsite server.

that doesn’t require I keep a full local copy of all the data

If you don’t do that, the place that you call “backup” is the only place where it is stored - that is not a Backup. A backup is an additional place where it is stored, for the case when your primary storage gets destroyed.

It is not a fork aiming to replace it. It is rather a spin with saner defaults to cater to companies as customers. The product which shall carry ondsel financially is their freecad compatible cloud offering, and the hope is to use that for elevating freecad itself too. They need their spin to be able to ship an ootb experience fitting their motive and brand. So if you would like a less confusing experience it might be something for you. Currently there’s a lot of borderline deprecated and also redundant functionality in freecad, so I hope that ondsel’s cleanup mantra will make it to the ootp upstream experience as well.

As far as I remember ondsel is working on upstreaming realthunder’s approach to freecad, but it is a lot of work to polish up because it touches so many parts of the application.

Here is a nice interview with one cofounder of ondsel where I have this information from: https://shows.acast.com/ohm-podcast/episodes/ep-12-brad-cto-of-ondsel

Ah interessant, vielen Dank!

Was ist 2017 passiert?

Just recently I listened to a very interesting interview of Brad Collette, the founder of ondsel. You can find it here https://open.spotify.com/episode/2TwCcFWC8VwQ4ctjBTZ0Xd?si=pNjFQOI0RCe0v1MU47mwpg

But why?

That depends for me on the height of the z-hop. Too much and the upward motion of the hop will pull filament out of the nozzle and worsen stringing. But that doesn’t happen to me when hopping a fraction of the layer height, then it helps to not deposit a blob along the way

Cold bed can be a problem sometimes due to the bed warping with temperature. I myself always probe with the bed at printing temperature for this reason
