Time to urgently make sure your favourite backend is generating decent AArch64 code and you app is compatible with a weak memory model...
Can you ELI5 this?

#42I envision there being a lot of ARM support issues across apps that I rely on. We finally got over the keyboard drama, I don't have confidence this will go well either.
You say it like it's a bad thing. I can't wait to have more competition as far as instruction sets go. Of course things will break but it'll give us a reason to make our apps and toolchains ARM-compatible beyond Raspberry Pis and small devices.

#43With this and AMD's Threadripper benchmarks, Intel really needs to step up their game.

The memory model of the ISA != the memory model of your code. C has a memory model and any correct C code is compiled to the correct ARM assembly. It's only really an issue if you are translating over x86 assembly, and then you probably have lots of other issues to worry about.
If you’re the one implementing the language’s memory model then it’s your problem isn’t it?
If you’re generating the machine code then it’s your problem isn’t it?
If you’re writing lock-fee code that doesn’t use the C memory model then it’s your problem isn’t it?

Yes, yes we do.

#46what does this mean for running docker containers on macos?
It means you better think about buying a thinkpad.
I moved to an X1 2 years ago when I refused to get the new keyboard and my 2013 MBP was on the way out, very happy to have Linux as the native OS for dev work, but I don't love the added time I do have to spend maintaining my own OS now.
Also slack and zoom for linux suck :(

#47What's been going on with the embedded ME/PSP in x86-compatible hardware for the last 10 years is ugly. If this is real--I'm hoping this evolves into a real alternative to that architecture though it's possible it could start doing the same thing.
Re: Apple will announce move to ARM-based Macs later this month
#48Interesting. I imagine they'll have to provide some sort of x86/amd64 compat layer as otherwise this kills every application available for macos right now. I hope they don't also continue to lock down macos (though I imagine they intend to) by restricting applications to only being available from the app store. That would set a terrible precedent for personal computing.

That precedent was set about a decade ago, and even here on HN there is a vast crowd of people who happily support(ed) that.

#49I would love to see new MacBook pros with the latest AMD Ryzen, speedy and power efficient, processors. I can understand the move to ARM, since iPhones and iPads are already there and it make sense to unite the ecosystem.
Fun fact: Kalamata is the second largest city in southern Greece. I tried finding why they named the Apple project like this, but couldn’t find anything relevant. Any ideas?

Depends on how fast they are and who knows, there might be custom hardware to help the emulation. I’m pretty sure while there will be issues 4-8h of battery life and your laptop working at full speed when not on the mains will be great wins and eventually worth the change.
