As an electonics labs person I applaude all efforts to mske our practise more renewable. However this is a circuit that I would have wired without PCB at all, directly point to point, wire to pin. Better than a greenwashed alternative is to avoid using msterial that is not necessary. Yet one also had to consider the whole lifetime of a product: ten throwaway circuits versus one very durable one etc.

I love freeform wire circuits.

I think parent comment is probably aware of gender inequalities in tech.

I don't think so, since he's making it clear that he, in fact, doesn't: "I truly don’t understand what the hope to gain from self-classifying this is “feminist”."

The rest of the comment shows that they understand the need to represent women as equally professional to men in tech. The first line is just a polite way to say "I think this is counterproductive" while leaving the door open for discussion. You may disagree (and I do,) but at least engage with the point they actually made.

I mean, the technical definition provided “the movement to end sexism, sexual exploitation and sexual oppression'” is expanded quite rapidly into including racism and then labor practices (which I’m very much struggling with the jump; the link appears to be that both involve power relationships?). And I’m not really clear why this doesn’t extend further into basically all of human suffering in any society. Or perhaps…

> expanded quite rapidly into including racism and then labor practices The jump you referring to is a quote with a reference attached. But in short terms so that might be useful to Google, but in short the concept of intersectionality means that things like feminism and anti-racism and other forms of prejudice can potentially be inter-related in terms of using different forms of marginalization as tools to enforce a…

I mean, your first complaint was asking the question instead of hunting down the about-me; your second complaint is that I need to recursively resolve all references before querying. At what point is it more reasonable to… simply ask? Or expect that a body of text is roughly self-contained, despite the infinite array of information that could have informed that body of text?

FWIW I googled it and found nothing to explain this. It’s not even clear to me that Ahmed engages in this behavior herself, of inverting the “intersection” from nexus between relating subjects, into a giant umbrella term called feminism

To preempt your next request, I’m not buying/reading the book(s).

> anarchism, so like yeah it wouldn't necessarily be a leap to extrapolate that and plenty of people do

The part I find to be a jump is to subsume it under feminism. The study of slavery and labor inequality can help to inform feminism is reasonable;

the study of slavery and labor inquality help to inform feminism, therefore they’re are really the same thing and feminism refers to both is a wild reasoning. It appears to be pure scope creep.

The basic logic seems to be: a relationship exists, therefore it is feminism. And I don’t see why such a definition won’t eventually consume all information ala 6 degrees.

Interesting experiment, but on the other hand, maybe 3D printing would have less emissions than an open fire? I’ve not tried this, but it sounds like a good way to get fast turnaround for very simple circuits: https://bsky.app/profile/castpixel.bsky.social/post/3mf52azn...

CO2 emissions from burning wood (and charcoal) can considered net-zero by some (I'm not really interested in arguing one way or the other) because all of the CO2 being released was initially trapped out of the air by the plant, not releasing "new" carbon that was initially trapped underground

There's nothing environmentally friendly about burning woods good old prehistoric ways. It releases tons of particulates and nitrogen oxides and some other toxic hydrocarbons. That's why it's illegal now in many regions to burn trashes in the backyard.

For me the next step should explore how to cut out the firing part of the process altogether, pottery looks cool but the process requires a lot of energy. Perhaps it could be done on a piece of wood planed by hand? You can get those fairly flat. Then use copper tape (or laminate your own copper really) with some homemade adhesive? Actually now that I think about it you could just make pine rosin (pine resin + alcohol…

Amusing historical note, that's where the word "breadboard" came from. Wooden cutting boards were readily available, and people would make circuits by screwing down tube sockets and other components.

What date is that? Petrochemicals aren't all stored in a big tank somewhere. My model is that there are many marginal sources which are not cost-effective to exploit, but which could be exploited with better technology or at a higher cost. I do not think we will ever extract all of these; instead, the cost of extraction will increase gradually, shifting incentives towards other energy sources. I don't think anyone re…

2072. This date hasn't changed from 4 years ago. Try google: At what approximate date will all known reserves of petroleum be exhausted, providing that the global rate of consumption and increase in consumption remains steady, and provided that all available resources can be extracted, even if we do not currently have the technology to do so yet? The fact that we do not know what the future will look like, means we s…

Your assumptions are equivalent to the "big tank" model. You assume that there's a fixed amount of petroleum, we know where all of it is, and we'll extract all of it. My point is that increased costs of extraction will push us away from petroleum before we reach a hard limit. Also, we could discover more petroleum -- you specify "known reserves" but it seems unlikely to me that we've really found all of it. (Not an expert though!)

Personally, I hope we transition to green energy sooner rather than later, but I think that these predictions are overconfident. A lot more will change in 50 years than in 4.

I'm sure the clay could be fired in an electric kiln powered by renewable/non-emitting power.

It's an art project

I want so badly for you to expand on this thought. What are you implying about it by describing it as an art project? What does art mean to you? Are you expanding on or disputing whether it is an experiment? Please, go on.

Meant to be a fun thing to do/experience/learn and not produced on an industrial scale. One small fire pit to harden some clay isn't going to make a material impact on total human CO2 emissions.

Do you not think it might be counterproductive considering every new activity in terms of emissions output? We need to reduce emissions, to do this we need systemic change. It seems unfair to place the burdon of reaching efficiency gains that can only come from economoes of scale onto anything that that has not reached scale.

Systemic change cam be seeded from small ideas. Allow the ideas to be inefficient no matter what they are, their sum will still be tiny compared to the mass industry of established ideas. If you want change ideas are a good place to start. If the ideas are good don't reject them because of their resource use in their embryonic stage, once they are established as good ideas we can turn our mind on how to make them efficient good ideas.
