I got a Prusa CORE One earlier this year, and so far I've been very happy. I have not ventured outside of the default settings though, and I use their own filament (only PLA). This has worked perfectly fine so far, but now I ran into an issue, and I figure it's time to come out of the "default settings"-bubble and learn some more about this stuff.

I am trying to print a Gridfinity holder for a rolling pin, so I tried to cut out a appropriately sized cylinder in a template with a boolean operator in Blender. When the print got to the concave portion, the print started to fail - uncertain how to best explain it, but the overhangs over the infill did not properly bridge and the filament started to warp so that the print head would hit it on the next pass (and make some nasty scratching sounds). I stopped the print when I noticed this. See an image here:

I am uncertain whether this is due to the model being poorly optimized for 3D-printing, if the printer settings for the filament were off or if I could've tweaked the slicing settings to achieve a better result.

Is it obvious, looking at the image, what the primary reason for this failure is?

Note: I've ended up printing this again already with a regular rectangular cutout instead of a cylindrical one, so I am just trying to learn more about what made this fail to learn more.

I am looking into getting a BOSS RC-5 looping pedal for my guitar, and I am curious if anyone has any experience with using it with Linux?

It makes use of this BOSS Tone Studio to allow adding additional backing tracks, but it is only officially supported for Windows and macOS. I could not find many examples of people using it on Linux, but for the most part any discussion I could find was in the context of their amplifiers.

I wonder if it should be straightforward to run it through Wine? As far as I can tell, you only need to set it up as a storage medium and connect it to your machine, although you can't just drag the files directly onto it.

It is not a deal breaker for me if I can't get it working, but it would certainly be a benefit if I could.

Recently at work I've been thrown into running some Python scripts in a Docker container (all previous Docker-experience is limited to pulling images from container registries to host some stuff at home). It's a fairly simple script, but I want to do two things simultaneously that I have so far been unable to accomplish: redirecting some prints to a file while also allowing the script to run a cleanup process when it gets a SIGTERM. I'm posting this here because I think this is mainly signal handling thing in Linux, but maybe it's more Docker specific (or even Docker Swarm)?

I'm not on my work computer now, but the entrypoint in the Dockerfile is basically something like this:

ENTRYPOINT ['/bin/bash', '-c', 'python', 'my_script.py', '|', 'tee', 'some_file.txt']

Once I started piping, the signal handling in my script stopped working when the containers were shut down. If I understood it correctly it's because tee becomes the main process (or at least the main child of the main process which is bash?) and Python is deferred to the background and thus never gets the signal to terminate gracefully. But surely there must be some elegant way to make sure it also gets it?

And yes, I understand I can rewrite my script to handle this directly, and that is my plan for work tomorrow, but I want to understand this better to broaden my Linux-knowledge. But my head was spinning after reading up on this (I got lost at trap), and I was hoping someone here had a succinct explanation on what is going on under the hood here?

Sad news - I have been very happy with CalyxOS, and not sure if I would want to continue using it without security updates or move to another ROM on my Fairphone 4. It seems perhaps that I would anyway need to reflash when they get to the point of resuming updates? Anyone get a clearer reading on that than me?

I have been contemplating trying out Ubuntu Touch which has according to their site 100% compatability with Fairphone 4 now, but there are some functionality that I think would struggle without, and if I can't get it working as I want, I wouldn't be able to reflash CalyxOS now. Getting a new phone to install GrapheneOS is not an option for me.

What are other people here using CalyxOS going to do to maintain a modicum of privacy on their mobile devices?

I am contemplating getting a stand mixer for baking purposes, and I've always known KitchenAid as the default choice here. I would instead want something European-made, but I am unfamiliar with the landscape.

Do any of you have any experience with European models, such as the Ankarsum or Bosch OptiMUM (what kind of name is that??), or any other?

I have a good food processor and blender from before, so I don't need it to be able to handle all kinds of things that stand mixers are not meant for, but if there's some extensibility beyond just kneading that I wouldn't otherwise be able to achieve with those devices, that would be a plus.

(Cross-posting this across several communities in hopes of getting some discussion.)

I'm currently building some indoor climate sensors for my home. My idea is to have temperature, humidity, noise, light, VOC and CO2 readings at a relatively high frequency reporting to my MQTT server.

I am currently setting up some different temperature sensors, and I want to calibrate them (hopefully just a linear offset) and evaluate them on some metrics, such as sensor-to-sensor consistency and accuracy.

To calibrate and evaluate the accuracy, I would need a source of truth, and ideally I would also be able to cycle it through a range of realistic values for the given metric.

What are your strategies to tackling these things? Do you assume the sensors are already well-calibrated and don't bother with this? Do you have a dedicated reader for any sensor value you would want to calibrate?

I am one of those guilty of always intending to donate, but never really getting to it. But now I sat down and took the time to donate to some of the projects that provide great value for me, and also listed the ones I did not donate to now for future donations. I also set up an overview to track where I donate to, so that I make sure to spread the donations well over time.

Just a friendly reminder to consider donating to the projects that provide value to you if you have the means!

As we all know, privacy starts with security, which leads many people in this community to seek out secure services / software, some relentlessly so.

Then life happens, and suddenly you find yourself naked in a back alley in Hanoi (or if you already live in the region, you might instead find yourself naked in Santiago de Chile), stripped of all belongings and at best some vague recollection of an unusually good night. What is your strategy to regain access to what you need to get back home?

An no, the staff at the hotel does not recognize you.
