Sometimes they’re visible from the other side of the room, other times you need either a magnifying glass and a bright light whilst holding the bottle upside down.

Consider the amount of strength required to make either movement. It might turn out that one way requires more strength than the other.

I didn’t see any other video in relation to this.

As I understand it, the author of the AGPL has recently posted about software that’s including closed source modules and the person who was told to cease and desist has documented exactly what the issue is based entirely on Bambu Labs’ source code. There’s also discussion about reverse engineering.

I don’t know if any of that is new ground or not, as I said, this is the first video I watched on the topic, it randomly turned up in my feed.

I think that below is probably a fair summary, but I note that I’m a FOSS user and contributor and this is my opinion.

There is a case to be made that there is an AGPL violation here and the documented evidence and commentary is growing.

More people with knowledge on the subject are apparently weighing in.

As a software developer, I think that this case is important because there is a growing trend by companies and individuals to hide source code from the community, even if that software was originally licensed to them under an irrevocable licence. In this case, as I understand it, the Bambu Labs software is a fork of Prussia Slicer, which itself is a fork of Slic3r, all of which is licensed under the AGPL.

We buy milk every fortnight and the date ranges vary wildly, which results in expired milk if we’re not careful.

Welcome to the community!

Apparently the petition went up in November 2025 and has a year to get enough signatures. Last I saw it was near to the halfway point of acceptance.

I came across it because I saw a post announcing that Inkscape was supporting it.

Basically two choices:

1. Find a project you’re interested in and make a contribution. Many projects tag certain issues with something like “Good First Issue” as a way of lowering barriers to entry. Other things are updating documentation, fixing typos, then you can branch out into patches and pull requests.
2. Make your own FOSS project.

Some reasons:

We don’t (yet) have flexible panels that would survive the abuse that curtains experience.

Vertical surfaces are not nearly as effective for the majority of cases in capturing solar radiation.

Windows have lots of obstructions that reduce the effectiveness of a solar panel.

Putting solar panels behind an extra layer of glass that would need to be kept pristine would be counter productive.

The voltages involved in solar panels would create an added source of danger inside the house.
