https://github.com/mu-semtech/sparql-parser contains an EBNF parser for SPARQL, an LL(1) language. You might be able to borrow code, not sure how well it translates to scheme. GitHub asked me to log in to see the gist so I'd have to have a peek later.

sparql-ast folder contains the relevant bits regarding the parsing.

Nice script. What is the reason to toggle the brightness?

Set up a Matrix bridge and promote it too. You can't force a community but you can inform and give choice.

The writing style and positive fighting spirit of https://lemmy.world/comment/3597938 is great. Would read a book of this person.

Latest ollama has support for AMD GPUs. I had to compile from source to make it pick up the GPU on my system.

Has that changed recently? I've ran ROCm successfully on an RX6800. I seem to recall that was supported, the host OS (Arch) was not.

It's bridged to Matrix. Not sure about IRC but I think the libera.chat bridge is gone.

Depends on how much the old banger is driven. The tipping point is much earlier than I expected.

I'd love to drive the old bangers more though. The rumbling sounds and the hope it'll keep up as the engine gets pushed beyond reasonable limits before the inevitable gear change. The whistling turbo as you reach its zone and the gently ticking valves of a cold engine. But turns out gas guzzling fun was never going to be a lasting treat in our habitat. As I write this, our neighbourhood has a reasonable chance of getting flooded because of the strange weather lately, and I am glad I've grown to appreciate the lovely hum of our electric minibus.

We need to travel less and enjoy it longer. Much much less. Every region is different. Our region has good public transport if you accept cycling for 30 minutes. Traveling 100km for work daily is bad for the environment. So we mostly need a culture change here. And people who lack the funds seem to care even more for cars here so we need cheap electric cool econoboxes with too, I guess.

Kubernetetes is crazy complex when comparing to docker-compose. It is built to solve scaling problems us self-hosters don't have.

First learn a few docker commands, set some environment variables, mount some volumes, publish a port. Then learn docker-compose.

Tutorials are plenty, if those from docker.com still exist they're likely still sufficient.

With that explanation I am still not clear whether the statistic on percentage of recycled batteries was car batteries, the battery industry as a whole, li-ion batteries, rechargeable batteries, ... I am honestly interested in which statistics you are referring to. Especially the evolution of recycling of car batteries and the regions where recycling and collection occurs.

It seems you are adding uncertainty and doubt on the topic of battery recycling which I'm not sure is grounded. We are well past the point in our environment where we can live our current lifestyle in the way we live it today. We have to adapt to a different lifestyle and make strategic bets. It seems clear that we should stop pumping up oil and electric cars may help there. I'm looking for research that indicates that current car batteries are waiting in stockpiles to be recycled but no plants exist to recycle them.

As far as I can tell, there are not even enough bad battery packs around to suit the diy hackers to reuse them for home energy storage and with some luck your research points me to where I can find them.

Are you talking about Li-ion batteries in general, or car batteries?

I don't think there are many car batteries to be recycled yet. Only the Leaf's batteries degraded sufficiently to warrant replacement and even those seem to be used with shorter range. Tesla batteries with faults get refurbished IIUC. The ev conversion market likes to use second hand packs and prices are strong because there are too few.

I have read that recycling is feasible and realistic but did not bother to check. Can you point to the research that says it is hard and that the batreries will serve no future use as is?
