How to use Apple Notes for instant equation results on iOS 18
It would be useful to everybody, online press, users, and even Apple, to use the correct language.
Notes do not solve equations, it computes expressions.
An equation is something like x^2-1= 0, and solving it means finding the values of the 'variables' that make the equality true.
Computing an expression is executing a algorithm writter as a mathematicak expression: 3*5-2 means multiply 3 by 5, add 2 and tell us the results.
The two things are wildly different, with different use cases, and very different complexity.

Adobe has clarified controversial shrinkwrap license terms, but the damage may have alread...

By the way, what Adobe says doesn't matter at all; legal terms are legal terms, and providing an worldwide exclusive license have a precise meaning, that no amount of explication from Adobe can change. I don't think Adobe has bad intentions here, i think they just choose the bad lawyer to write the text. But the text is there, and it holds if you accept it. -

Why Apple uses integrated memory in Apple Silicon -- and why it's both good and bad

Being able to control how much RAM is installed allows Apple to guarantee that all memory channels are filled and being utilized, maximizing performance.Yes, and do not forget another point: scalability: memory bandwith scale up with the chips, from M2 to M2Pro to M2Max to M2Ultra. The number of channels go up with the chips.According to Anatech, the M1 had 8 memory channels. The M1 Pro 16, The M1 Max 32, the M1 Ultra 64. If i understood well, a DIMM include two memory channels. This means that in order to a similar performance, you need 8 DIMM in parallel for the M1 Pro, 16 on the M1 Max, 32 on the Ultra. I suppose that M2 numbers are similar or a bit larger. It doesn't seems very practical to put 8 DIMM on a Mac Mini, or 16 in a Mac Studio or in a Mac Book.Without considering power considerations. I do not think there is a practical alternative for Apple.For the Mac Pro, yes, there could be alternatives, like a NUMA architecture (Soc memory plus external memory). But that would require specific chips, and specifics extensions of the OS. To cover the market for which 192 Gb of Ram are not enough. Does the size of this market justify the investiment ? I do not know.For the author of the article: go back to your 101 computer architecture lessons. DMA is not for standard CPU memory access, computers do not use memory busses anymore since at least 20 years, and interrupt is not used during normal memory acces. DMA is used for I/O, to allow memory access without going thru the CPU. And this also was true at the 6502 times, i think situation is a little bit more complex today. -
