“The raw materials for epoxy resin production are today largely petroleum derived, although some plant derived sources are now becoming commercially available (e.g. plant derived glycerol used to make epichlorohydrin).”

In the post-fossil fuel age, where is the net carbon supposed to be coming from? Unless we're using limestone, it's from the air, so there can't be net emission.
In the not-yet post-fossil fuel age, what matters is displacing fossil fuels as quickly as possible, not the relatively very minor amount of carbon embodied in the renewable energy machinery.
It seems to me you’re thinking of this in wayyy to much of a binary. It’s not pre-fossil fuel vs post fossil fuel - it’s how do we transition each thing we use fossil fuels for.
Like if we end fossil fuels for energy, the cost of plastics will skyrocket. They maybe don’t contain enough carbon on their own to drive global warming, but we still need alternatives because otherwise that’s a many-billion dollar industry that is going to oppose stopping burning fossil fuels for energy.
It’s interesting because there is a view that we already have this. You can deploy most of the infrastructure you need to do the kind of thing the author is talking about using a few hundred lines of docker-compose.yml. The author alludes to some of that - grafana, postgres, etc.
What is missing is the glue, or the business logic, or maybe just the custom frontend you can charge a lot of money for ;)
Using any blogging software and stripe or square or paypal you can setup an online store that comes close to the experience that shopify offers - to the customer. But the backend is nowhere near as good as shopify - you are copy-pasting addresses over to usps or ups, tracking orders with notes attached to stripe payments, and god forbid you should want to automate any transactional emails related to it. Oh, and your system falls apart when you start taking orders via ebay or etsy - since you linked so much process to stripe. So the whole thing devolves into a carefully crafted google sheet.
Which is all to say, i agree with the author - but i feel like we are winning the war, it’s just the battlefront moved from deploying backed services to gluing the pieces together.
That was their goal, but in the past couple years they seem to have given up on client-side-only ai. Once they let that go, it became next to impossible to claw back to client only… because as client side ai gets better so does server side, and people’s expectations scale up with server side. And everybody who this was a dealbreaker for left the room already.
Apple thinks they can get a best-of-both-worlds approach with Private Cloud Compute. They believe they can secure private servers specialized to specific client devices in a way that the cloud compute effort is still "client-side" from a trust standpoint, but still able to use extra server-side resources (under lock and key).
I don't know how close to that ideal they've achieved, but especially given this announcement is partly baked on an arrangement with Google that they are allowed to run Gemini on-device and in Private Cloud Compute, without using Google's more direct Gemini services/cloud, I'm excited that they are trying and I'm interested in how this plays out.
Apple integrated ChatGPT as an opt-in that made the mainstream users feel like Apple was delivering on some of that marketing. Apple also delivered "high wow" features like auto-stickers and other such silliness. Just as the privacy issues are maybe a bit of an HN specialty, HN is also maybe a bit more prone to "Apple Intelligence" brand cynicism than mainstream belief.
I'm excited about the attempt at privacy because I'm on "Team Keep Siri Dumb". I like dumb Siri. It reliably meets most of my needs, setting timers and managing house lights. I'd rather Siri stay dumb and I would never opt-in to ChatGPT Siri as some of my family has, but if Siri "has to" get smart to survive, I will celebrate whatever privacy wins are still available as my only hope that smarter Siri is not something I need to just disable entirely (and lose my "friend" in charge of my timers and house lights in the process).
I stated that I am not naive and am not entirely convinced by Apple's sales pitch that the Private Cloud Compute containers are encrypted with keys in a way that only your hardware device can read in such a way that the PCC is an extension of your device.
I just think it is useful that Apple is trying something along those lines and wishful the guarantees work half as well as they claim they do, because that's a good goal to have in theory even when it fails in practice against dedicated threat actors.
And yes, to be fair my personal day-to-day threat model currently is much more concerned with the evil advertising company known as Google than it is with government actors. Even if Apple's Private Cloud Compute only means "private from Google" that's still a win for me (and most of the information I was looking for when I saw this headline, because my first fear was that the advertising company Google was involved).
You will also need to accommodate the banking apps updates, banks will not support very old versions of their apps( very old varies but probably about a few months ). Beyond that the new versions may require hardware support that may not be available in a decade old phone.
3d printed shoes are… almost a thing(1). Clothes, not so much… some experimental high fashion fabrics, but nothing you’d wear under normal circumstances.
But to your point about PFAS, afaik no common 3d printing materials contain PFAS - at least not filament ones, i don’t know much about the resin printing world.
The only place PFAS is used in an FDM printer is the filament guide some printers have. That's a Teflon tube that the filament travels in towards the hotend.
Bowden style printers tend to have a long tube, direct drive printers sometimes have a short tube fully contained in the hotend assembly.
I don't see how PFAS can be used as a filament in FDM printer. It's not a thermoplastic, that's one of its advantages as a material.
> as captured by their slogan, "from the river to the sea Palestinians will be free"
The mental gymnastics required to make a call for freedom into a call for war are astounding. If i say “free tibet” does that mean i want war with china? What part of “free” is a threat to the people of israel?
> despite that they launched the war first every single time
This is such weird playground-like defense - “They started it!!!”. The actions and stated intentions of israel leading up to the 1948 war are pretty easy to see as a declaration of war - claiming other people’s land as part of your state. And then later Oct 7th is often portrayed as hamas “starting it”. But there were over a thousand gazans held by israel without charges on oct 6th. If israel is justified in murdering 80,000 for the hostages taken in oct 7th - is hamas’ attack not justified by their people held by israel?
To be clear, i’d say in both cases the murder of civilians was unjustified, but i don’t see how one can be justified while the other isn’t.
I assume that you are engaging in good faith, therefore I will respond.
On the meaning of Palestine will be free, don't westplain the Palestinians by reading your interpretation into their mind. Instead, listen to what they actually said.
A lot of misunderstanding about Israel stems from people not reading the situation as it is, ie: listening to what both sides actually say, instead, they are listening to their own projections of the Jews and the Palestinians.
And your take that on Oct 6 Israel held thousands of Gaza doesn't explain why Israel would unilaterally pull out from GAZA in 2005, which is just another way of saying that it's likely to be false.
I’ve encountered online MANY israelis calling for gaza and the west bank to be destroyed and every palestinian to be killed or kicked out. Does that mean every israeli believes that? Knowing what everyone believes takes more than cherry picking the worst beliefs.
> In April 2022, there were 4,450 Palestinian security prisoners in Israeli prisons – including 160 children, 32 women, and over 1,000 "administrative detainees" (indefinitely incarcerated without charge)
> If something enables aggression, because it makes counter attacks unreasonable, that seems like a fairly nice thing to have more of
You’re imagining a world where this kind of tech is equally distributed. It’s not. Israel spends something like $30b/year in defense (in part due to ~$7b/year from the US). Gaza has something like $0.3b to spend. The consequence of that asymmetry is one of them has a missile shield, the other has more than 80,000 dead citizens, famine, and virtually no infrastructure left standing.
Gaza's "air defense" is hundreds of miles of tunnels, civilians just aren't allowed to shelter in them. Hamas having better technology wouldn't change the fact that they're not interested in protecting civilians.
I’m not going to defend hamas’ choices, but i think it’s disingenuous to say that they have the ability to protect the people of gaza. A few thousand fighters in tunnels is possible, but millions of civilians? And wouldn’t that be more of this “using human shields” stuff people like to point out so often?
I am imagining a world, where cheaper access to defensive technology will make defense more viable. That's seems like it will simply be true directionally.

if they were obtained from non-fossil sources - but they weren’t, and the industry hasn’t switched and may never switch to plant based.
Also, what you said isn’t necessarily true even with plant based resins. What is the carbon cost of producing new resin vs recycling old?
There’s more to the impact of a material than the carbon stored inside it.
Yes, we were all duped by the recycling industry. No that doesn’t make all attempts at recycling a lie.
