ok? I don’t think anyone said they do.

the point was, someone claimed that only Macs have unified memory, so I gave some counterexamples, not an exhaustive list of all counterexamples.

I think they’re ARM-based, so yes.

which is not unique to Macs. all ARM PCs have unified memory. AMD is doing it in some of their x86 now too (Strix Halo) and Intel also have it with their Core / Arc integrated graphics boards - https://www.tomshardware.com/pc-components/gpu-drivers/intels-new-graphics-driver-lets-you-dedicate-up-to-87-percent-of-laptop-memory-capacity-to-the-igpu-for-vram-core-ultra-cpus-get-shared-gpu-memory-override-feature

you’re talking a feature of ARM architecture vs x86.

lots of companies besides Apple are making ARM PCs, and Linux (and Windows and other OSes) runs fine on ARM with unified memory.

you shouldn’t go by just one name unless you’re the most famous person with that name in the whole sector - i was confused why the BSD Theo was advocating Linux now.

Iceland shouldn’t be on this, it didn’t exist until ~20 million years ago. Pangaea broke up ~200 million years ago.

Probably lots of others, like most of Japan shouldn’t be labelled either.

better keep the fire away from the naquadria deposits.

Fabrice Bellard is ten Ronalds.

that’s reasonable.

bonus fun fact - the etymology is connected - “axle” comes from older words for “shoulder”, or “armpit”, which survives in some regional Englishes as “oxter” - the connection is apparently that you’d carry a person by putting their arms up and linking at the shoulders, much like an axle is how wheels carry a cart.

No, that’s what I meant by not an axle.

But, come to think of it, we can swing our arms round and round, more than 360°.

How about this insect with a pair toothed gears? Not an axle, but still amazing!

“The juvenile Issus - a plant-hopping insect found in gardens across Europe - has hind-leg joints with curved cog-like strips of opposing ‘teeth’ that intermesh, rotating like mechanical gears to synchronise the animal’s legs when it launches into a jump.”

right, even trains don’t need diffs, the conic-slice wheels take care of turns fine without.

i believe there was some early speculation that the unprecedented temperature of the Trinity test might ignite the atmosphere, somehow making the nitrogen burn, but that would be a chemical reaction, not a nuclear reaction.

Alpha and beta decay are types of fission.

no, there are lots of atoms splitting inside your body every second.

a single U-235 atom’s fission, releasing ~200MeV, (~30 picojoules), in ideal circumstances could maybe nudge a very small fine grain of sand (~ micrograms) enough to see movement (small fraction of a millimetre) under a microscope .

It takes months of refining to make nuclear fuel that’s suitable for sustaining a chain reaction.

it’s an interesting question, I’m glad I did the research checking that the orders of magnitude match!
