Two are longtails, one of those is a Big Dummy w/ an e-assist, the other an EdgeRunner, no assist. Bike 3 is an Orbea Katu with a nice front frame rack/basket. All three bikes are trailer capable. I also have a WW2-vintage Raleigh 3-speed, retrofitted with a Dutch front frame rack. I try not to overindulge on the e-assist, so, not more than once a week unless there is a reason, like heat, or trailer.

@meanderer @cstross I am not sure. A few years ago I bought a laptop sized to run LLMs locally (96GB ram), and while it is an awesome video editing machine, the (older?) local models generate text ... word ... by ... word. It really gave me an appreciation for how much computing is required to make these things go. Specialized hardware for high-bandwidth low-precision FP helps. People playing games w/ "teams of agents" require even more CPU oomph.

@martin At the scale of the US, we never get nationwide overcast, nor nationwide lack of wind. We DO need to overprovision both batteries and wind, and distribute that overprovision across the country, and connect it nationwide so that power can be sent from sunny places to overcast places when that occurs. Putting "Do the math" in bold face is not a proof. If you think it's that obvious, the proof should be easy.

That horse might be out of the barn, but so far, I have not used AI for any images except tests of the AI itself, so, not quite everyone is doing it.

Dear adventurous Go users who are playing with SIMD in 1.26 pre-release. Coding your feature checks like this:

func init() {
   useAVX512 = archsimd.X86.AVX512()
}

will yield not-best code, because the compiler is looking for guards that check archsimd.X86.AVX512() in order to (whenever there is a choice) enable the AVX512 versions of operations, e.g., mask registers versus bit masks, that sort of thing. (512-bit vectors will also force AVX512).

@martin If you cite an article, and then call it naive, then you haven't really cited anything. The Pacific Intertie is not small. https://en.wikipedia.org/wiki/Pacific_DC_Intertie "The line capacity is 3.1 gigawatts, which is enough to serve two to three million Los Angeles households and represents almost half of the Los Angeles Department of Water and Power (LADWP) electrical system's peak capacity." "When completed in 1970 ... estimated to save consumers in Los Angeles approximately US$600,000 per day"

@martin the wikipedia article that YOU put up there said multiday events are very rare, once per 5 years. Not 30 days. The US already has things like the Pacific Intertie, connecting Washington State to southern California on the west coast -- and this was done, for hydropower, so it was already judged to be worth it. You need to quantify. "Astronomical" is not a number. The things I expect will be electrified in the future include steel, concrete, ammonia, and fresh water production.

@martin but not much more solar because the 24-hour surplus can be accumulated over several days. Obviously the batteries will cost more, but the larger amount of storage allows gentler charge+discharge and provides more opportunities for load management -- the batteries will have a longer service life. I'm not seeing a proof of impossibility here, and batteries are still improving.

@martin Looking at the wikipedia page: "Events that last more than two days over most of Europe happen about once every five years." And most of them are 24 hours. If the day/night ratio is a cloudless 12:12 and load is Y watts, then solar capacity needs to be 2Y , and battery capacity needs to be 12Ywatt-hours. Away from the equator, say worst is 6:18 then solar needs to be 4Y, and 18Y watt-hours of storage. If, rarely, an entire day's production is missed, then 42Y storage,

@martin We an also rearrange our consumption so that loads are curtailed when the weather is unfavorable. Assuming we electrify processes that are currently done with fossil fuel, those will be large loads, and shutting them down for the duration of the worst 1% supply shortages will reduce the energy storage needed -- and only idles the industrial process 1% of the time, not a large loss in production.

To me it looks like panic at the loss of white majority and political power, and they are flailing, destructively, hoping to blow up the world so that the rubble will land "better".

@mattblaze@federate.social @cstross@wandering.shop @Migueldeicaza@mastodon.social It depends on the safe language. I've translated C into Java, "pointers" gets translated based on whether they are truly pointers, pointers indexed into a single array, or pointers indexed into multiple arrays. "Free" becomes a no-op, "locals" that are addressed become heap allocated. Array bounds are checked, there is no use-after-free. This will be harder w/o a GC, if they just hulk-smash it into Rust with unsafe, that will be bad.

To make a (very stereotyped) analogy w/ transportation, if someone says "people should ride bikes" a common response is "what about the disabled?". Standard reply is "well of course they can drive, everyone else should bike/transit". But if there is no whole-population market for cars, will any get built for the disabled? What will they cost? (auto-translation follows, and I translated back to check)
