Linus Torvalds's faulty memory (RAM, not wetware) slows kernel development


Apple Silicon has RAM built-in. It cannot be an ARM64 MacBook.

There is no RAM slot on M1 or M2 MacBook. All the RAM come inside the SOC. There is no way Linus ordering RAM for it.

Apple's M1: the fastest and bestest ever silicon = revolution? Nah, there's far more interesting stuff happening in tech that matters to everyone


Re: Well...OK

> But the 4U example, if we go with AMD and their 64 core CPUs (7702P), they currently draw max ~4.4W per core (from the TDP) compared to Apples cores (firestorm) of ~3.45W.

You have missed the power drawn from chipset, ram and so on in the AMD cores when comparing to M1. Hence you figures missed the reality by miles.

Saturn's largest satellite, Titan, is drifting away from its planet 100 times faster than previously thought


I can and did leg pump a swing around the top of a swing set.

I have to object the phrase "We don't think Titan will escape, because eventually the resonance locking process won't be able to operate, just as you can't pump your legs hard enough to swing around the top of the swing set,” said Fuller.

I had done it a dozens times when I was a child. No, not on a chain one. Here is a video of someone else did it.

Re: In a world, where smartphones aren't shitty PCs

Were you one of the two people bought a HTC Windows Mobile?

How many apps in your full choice installed? 2? 3?

"Other apps rely heavily on APIs in Google Mobile Services. And that means that even if you're able to transfer them over to the P40 Pro, you'll likely end up with an experience that's ultimately crippled, or fails to run entirely."

In case you want to flee this wretched Earth, 139 minor planets were spotted at the outer reaches of our Solar System. Just an FYI...


Re: Detection

That's a brilliant idea. The only problem is, we don't have the technology.

Sure we can make something as bright or even brighter than the sun in term of brightness per unit area. However, even if we cover our whole planet with this light, it has to be 10 thousands brighter than the sun to get the same output as the sun since the sun is 10 thousands bigger in area. And then TNOs receive double brightness. I don't think it really helps. And the for all the energy of humankind has collected the entire human history, cannot light it up for a second. At the current rate of our entire population increasing energy consumption, sustaining it running is not achievable for thousands of years, even if we put all our energy harvested to it.

I am sure we have better ways to do it as well as better use of the energy now or later.
