Two reason for x86 (IMO) and 3 reasons for ARM.

I've thought for years that the overhead of the extra decoder hardware and legacy cruft was non-trivial (though Intel claims that's not true). The evolution of ARMv8 (where ARM went much closer to it's RISC roots) seems to disagree. This explains the performance per watt issue (and potentially some IPC).

That said, scaling IPC (instructions per clock) seems to have a pretty big limit. x86 has basically hit a wall and it's been lots of time and research for small gains. Additionally, the biggest challenges in large systems is that the cost to do a calculation on some piece of data is often less than the cost to move that data to and from the CPU. As Apple increases cache size, frequency, and starts dealing with bigger interconnect issues, I suspect we'll see a distinct damper on their performance gains.

Qualcomm (and ARM as the designers of the core) has a very different problem to solve. They can't make money off of software. They make money when they sell new chips and they make more money from new designs than from old ones. This means incremental changes to ensure a steady revenue stream. Since Apple having a fast, proprietary CPU doesn't actually affect Qualcomm or ARM, they most likely don't even see themselves as in direct competition. Most people buy Android or iOS phones for reasons other than peak CPU performance and Qualcomm is fairly competitive with a lot of these (esp actual power usage).

A further complication is that they also need "one design to rule them all". They can't afford to make many different designs, so they make one design that does everything. Apple doesn't need to spend loads of time and money trying to optimize the horrible aarch32 ISA. Instead, they spend all that time on their aarch64 work. ARM and Qualcomm however need to add that feature so the markets that want it still buy their chips.

Apple shipped their large 64-bit design only a couple years after the ISA was introduced. Put simply, that is impossible. It takes 4-5 years to make a new, high-performance design. It took ARM 3 years for their small design (basically upgrading the existing A9 to the new ISA) and closer to 4.5 years to actually ship their large design (A57) and another year for a "fixed design (A72, though it's actually a different design team and uarch). Though the gap has been closing, 2.5 years in the semicon business is an eternity.

A crufty ISA and non-CPU scaling problems seem to explain Intel/AMD. A late start, bigger market requirements, and perverse incentives against increasing performance seem to explain ARM/Qualcomm
I've run CPUs at 100 C. It's not like they melt at that temperature or something.
You get paid for your work. You can change company you work for. If you don't want to work for company, you can try running self-sufficient farm - which is how peasant gained food.

Except that peasant did not owned the land. Could not make his farm larger nor smaller. If lord decided you will produce more grains instead of vegetables, peasant had to oblige regardless of own preferences. And peasants had to give part of produce to lord. And had to use Lords mills and what not instead of choosing them in free market.

Nor could peasant change occupation or marry without Lords permission.
This happened to me too. I suspect the reason is that I used the email address instagram.[a few random letters]@mydomain.com. I'm guessing it triggered their bot detection.
Yes, you're right. My bad.
Instagram is riffled with semi-nude photos of women that I seriously doubt it has any real value whatsoever. And it's kind of surprising considering that FB has a very strict policy when it comes to showing nude pics. They should have brought down the hammer long ago.
Side lessons seems to be that scammers have access to a lot of your personal info, which can fool you, and that you should never ever give an OTP over the phone.
Would love to hear more about what you desire in a photo sharing experience. My email should be in my profile if you want to chat.
That’s different. Rendering happens entirely on the GPU, so the only data transfer is a one-way DMA stream containing scene primitives and instructions.
>or exhibiting any kind of agitated respiratory state in public

The only sizable population of people that I still see out in public that aren't wearing masks are joggers. I wonder if and when we will put a stop to that.
Pepsi leaves a very nasty lingering sweetness at the back of my throat for hours after drinking it. There would be no contest if I was presented a blind tasting between the two and I could likely identify diet and zero varieties of each brand.
Also another data point suggesting that the virus is much more contagious than the early estimates said.

I personally don't see how the test, track and trace efforts that have been touted as the only way to open things up can work with a virus with these characteristics. You would need to test a huge percentage of the population each day with quick results tests and something like that is many months away from being possible assuming it ever would be possible.
That’s a first:) never thought I would get into a privacy policy page and enjoy reading it... Spice girls lyrics are indeed much more interesting;)
But how many students but MacBook Pros?
I came back from a trip to Thailand, India and had a 12-hour layover in Hong Kong. Even during the flight from HK back to SF, I started feeling a bit sick. That night I went to bed with a 103 fever which lasted for a couple of days. Picked up a severe dry cough that last for 4-5 weeks. A week later, news about coronavirus had started to spread, so I went to see the doctor. After testing a cheek swab sample, he said I didn't have corona but I also didn't have the flu. He said I had some sort of virus which wasn't reassuring. I felt extremely tired and cold for weeks after coming back from my trip. Pretty sure I had the virus especially since it wasn't diagnosed as the flu.
I do the same. To help with 'maintenance' (adding par to newly added files, checking and handling integrity for existing ones) I wrote a small utility you may like: https://github.com/brenthuisman/par2deep
It's gotta be 100°C.

The top cover part between the touch bar and the screen regularly runs so hot that touching it really hurts. Can't leave my hand on there for more than a second or two. Ran all sorts of diagnostics and according to those everything is fine.(MBP 2017)
When I proposed a course like this 35 years ago (with then-current tools), my colleagues told me that this was “not university-level material”. CS students who don't know how to use tools effectively, and how to learn new ones are going to be forever at a disadvantage.
We don’t know the R0 in the US yet. We need widespread testing that we don’t have to evaluate it.

Evidence out of NY today says it’s possible 14% of the state has already been infected. That’d point to a pretty high value.

There may be a general pessimism appropriate for anything complicated, but predicting the outcome of a complicated thing is complicated, which means that we should be pessimistic about the reliability of pessimistic predictions.
Many years ago I worked for a small analytics company bought by Amazon. My job was to analyze and report on the rise and fall of various product sectors on the web. We were in a unique position at the time, with the ability to see what URL's people were visiting. Reports we presented to Bezos, Jason Kilar and team, were used to make acquisition and growth decisions. In one case we found that that toys and plus size women's clothes were the top sellers for ecommerce in the US. They looked at the data and backed out of buying one of the major e-commerce players in toys and instead launched their own toy site / section. It was the beginning of Amazon moving away from Books and Music and into all other products.

The point is that competitive data is what drives decisions for product and segments in all areas of retail and business. Either in house or outside. Gathering that data from within your property is no different than using an outside agent.

You are acting as if they're spying on their customers, when the customers are you and me, not the reseller using their platform/space/warehouse/services.
I remember those macbooks got so hot that it was physically painful to touch the metal under the screen near the magsafe charging port. That was fun.
This reminds me of a Planet Money podcast where they try to figure out the characteristics of the most typical American, or as they put it "who is the person I'm most likely to run into?"

To construct this archetype, they used the mode of various dimensions rather than the median or average.

Why would it be? China, South Korea, Hong Kong have all pretty much managed to lower their amounts of new cases down to basically zero, and their society is open for business albeit with social distancing and mandatory mask usage.

The trick is to NOT stop testing once your case count starts going down, instead give the test to everybody that wants one.

A few million spent on 99.9% negative tests daily > a few billion spent on the economy being shut off daily
Similar story. I used a real-life name/surname (just not my real one), matched with a similar real email. I never got in. I never bothered. Now when I see (before COVID) people on the train tapping like junkies on the "stories" I smirk and think how lucky I was to avoid this mindfuck.

It's Bloomburg so take commentary with a grain of salt. There's no one reason as much as a lot of great ones. Their own CPUs are far more power efficient, especially with light loads but notably they have wider power controls that allow for much lower 'low wattage' use. So Battery life will get better. Then you have performance, even assuming they were not moving to 5nm you would be looking at i9-destroying performance from the 8 firestorm cores, each on their own able to beat single-core performance from an i9. And that's before you think about the fact that the IceStorm cores can run full throttle with FireStorm. This laptop is going to have hilarious benchmark numbers. Think iPhone SE for the PC market.

Then cost is the huge one. Obviously it allows them to move down-market or up the per-unit profit while reducing iPhone CPU R&D costs on paper.
Considering how they came up with Swift, I'm not surprised. They just "get it" with coming up with efficient, yet practical approaches to technical problems.
When the French revolution came along, it swept away the aristocrats regardless of whether they were abusive or kind and paternalistic to commoners. Mobs don't frequently make moral calculations the same way that individuals might.
No that's what I meant. People shopping and therefore not at work. Therefore intuitively I would expect the population tested to be less contaminated than the population not tested (because at work).
I wonder if we did these preliminary tests with the flu if we would see a large death rate drop for influenza as well
Couldn't they use Azure?

Of course there are other reasons to use physical servers.
All three could push the true total higher, but number two easily could push it lower instead. And I'm not a microbiologist but I think lack of antibodies only means that we won't be able to test for past infection. The seronegative patients (determined by a very precise method for measuring antibodies) in the second cited paper were still able to clear their infections.
same thing happened to me except I didn't bother going through support. I dug a little more a few years later and it turns out someone had put my email address in their account although they had signed up and logged in via phone number so it didn't matter that they didn't have access to the email associated with the account.

I was able to take over the account since my email was associated with it. I wiped the pictures, deleted the account. signed up again with my own mobile number and email, setup 2-factor so it couldn't happen again and then deleted the app.
In my city pay rate is entirely based on tenure. People just starting out for the city have very low pay, people about to retire have insane salaries. Maybe it is more helpful to just generically say compensation and ease of removal needs to compete with the market.
There's no reason they'd have to be down for two weeks in that case. They could use a binary distribution to immediately get back into shape, and then switch over after compilation's finished, or they could compile without -OX and it'd take almost nothing, and then they'd be good to go.

Really, though, nowadays compiling everything, even compiling things for optimal performance, doesn't take that long. Your production machines shouldn't have web browsers, and without the C++ garbage behemoths on it, compilation takes like half an hour on most machines.

I'm not a Gentoo user, but it's kind of silly to act like it makes recovering substantially harder than any other distribution.
TDD- Test Driven Design, yes
I mean 10rpm, really! A 10" fan at 10rpm moves about as much air as a 2.5" fan at 160rpm.

You're not trying to move huge amounts of air, since heat transfer from the laptop to the air is pretty slow. You just need enough movement to clear out any hot air that is building up under the laptop.
Assuming that the information would be behind at least a password entrance that a user had setup, Amazon breaking through that would be considered illegal unless they had a court order or something. They can peer into metadata that your machine creates but I think looking at private information on a server that they lease out would be illegal. Maybe I'm just hopeful?
There's no way to know who you are from the page, it's completely anonymous. For me that's always a big big warning sign for any site.

Also taxis and rideshares get a spike in orders, more coffee and food is taken to go, more people visit bars and pubs for afterparties, more souvenirs are bought, ... Big events cause a lot of ancillary spending to happen.
Can only speak for Denmark, where I'm from, but I'd venture that at least 50% of students have MacBook Pros. This is simply based on personal experience though. I might be way off. This is for the last three years of High School equivalent. University varies a lot depending on your field.
It’s a very rough estimation. Basically ((core + L2 area)/(total die area))(Total transistors on die).

For A13 with unified L2, I used L2 per core.

Of course, transistor density isn’t consistent across the chip, but this should be good enough for the relative comparison I’ve done.
Also don’t know if people with antibodies can still spread the virus to others or whether antibody levels (not just presence) determines whether you can be reinfected.
> but given the social distancing efforts, NYC didn't end up facing shortages

Another reason (warning, just from reading the news here and elsewhere) might be that it seems ventilators aren't as useful with Covid-19 as expected, and possibly actively harmful in a number of cases (again, this is just my rehash of what I have read).

From what I read doctors now try to use just proning and extra oxygen for as long as possible even if ventilators are available.

People actually working in healthcare or who have first hand knowledge should feel welcome to update this.
I believe any website that is behind the walled garden should be deindexed by Google and other search engines. Whether it's a newspaper, Q/A websites, social media, or anything else. It's only fair. When users search for something, they should only get results of web pages whose content is accessible to all without having to sign up for an account.
That and people want brightness. The legacy MBA that set that benchmark had like a 250nit display. Now the 400nit model on the new MBA is seen as 'dark'. The iPhone 11 Pro nears 1000 nits.
WOW! Finally WebGPU. Web Games will become a thing now!
My first time at CES (and AVN in the same week), a number of years ago, I left with something that resembled the flu and a sinus infection. Everyone told me that's typical.
MOSFETs can go way, way higher than that. There are CPUs (well, microcontrollers) that go way higher than that.

Whether 100°C is fine for a CPU is a question for the individual CPU.

Maybe I am just crazy but I had to go back and use XP for a few days for a project I’m working on (long story). After being on it and going back to 10 I honestly miss it in a lot of ways.

The UX on Xp was so clear, I still know where all the settings are and how to use them. I felt so in control. Now on Windows there are like 10 different settings menus with completely different design languages. I can’t find anything without search (and search is a disaster in and of itself). I can’t control updates well and in the last year there have been multiple updates that borked machines.
>and MOFSETs can go up to 115C

Mosfets have a maximum junction temperature of about 175C
I had the opposite conclusion. There are between 10k-15k COVID-19 associated deaths in NYC, depending on how you count (the higher rate is consistent with the excess-mortality data, I believe). That by itself produces a range of ~0.56%-0.86% if you assume 21.2 % of NYC has been infected (larger range if you allow for some error on the infection rate, obviously). Moreover, we don't know what fraction of the currently-infected who will die have already died. A reasonable guess might be 50%, which would mean that the fatality rate for NYC is somewhere between 1.1 and 1.7%.

Either way, based on NYC, 0.5% might be a hard lower bound on the all-population fatality rate (of course, maybe NYC is not a representative sample for some reason)
my main complaint is watching videos on desktop web or the mobile app - there's no way to control play/pause/scrubbing. you just have to sit through it and if you miss any of it, watch it again from the start.

same goes for tiktok i believe.

this isn't an issue with the mobile version of the website.

anyway, rant over - i hate mobile apps.
Honest question: why do you need ethernet onboard a laptop? USB-C ethernet interface adapters are cheap; could you not simply get a few and leave them on the ends of the ethernet cables to which you regularly attach?

These days, for most users (you and I included), very rarely if ever is wifi inadequate. If, for speed or security reasons physical ethernet is needed, the adapters are small and cheap.

I don’t understand the dongle hate.
This study doesn't appear to suffer from the same methodology problems as the Stanford study of a few days ago. In that study, they recruited people through Facebook, and reported an infection rate that was low enough that it could have been caused by false positives.

Here, it's closer to a random sample, but more importantly it shows really high rates. Those rates overwhelm any error due to false positives.

Also, it shows numbers that are in line with our intuition. It shows higher infections in NYC, and higher infections among blacks. That reflects what the hospitals are seeing.

This study may well be really good news.
AVX is widely used in things as basic as string parsing. Does your application touch XML or JSON? Odds are good that it probably uses AVX.

Does your game use Denuvo? Then it straight-up won't run without AVX.

People are stuck in a 2012 mindset that AVX is some newfangled thing. It's not, it's used everywhere now. And it will be even more widely used once AVX-512 hits the market - even if you are not using 512-bit width, AVX-512 adds a bunch of new instruction types that fill in some gaps in the existing sets, and extend it with GPU-like features (lane masking).
> The only 'con' is the pushing of Snap packages.

I am disappointed that snap still forcibly clutters everyone's $HOME with an extra directory[1] that cannot be moved or renamed. It was reported four years ago, and nearly a thousand people have joined the bug report. The glacial pace at which they're addressing this problem makes me hesitant to embrace snap.

True. I recently picked up Albert [1] on my Ubuntu machine because I was missing spotlight search. So far it works well - it would have been nice if something like it was included by default.

It's all good; I was asking because I legit didn't know, and couldn't think of anything off the top of my head. I don't work on Cargo, so I'm not as in-tune with its development.

So, I am still not 100% sure that I understand, mostly because each package can only have one library, so this would only work if you wanted one plugin. I guess maybe if they were all in a workspace?
> The is absolutely no veil between the hypervisor and the guest virtual machines. Not in the EBS either.

This is 100% true. To do any useful computation on your data (read, what you're using all AWS for) they have to have 100% visibility into your data.

> If they say they won't read your data, better trust them. If you don't, stay away from their datacenters.

That's it, right there. All of this is based on Trust in Amazon, not some technology that provides any assurances, much less proof, they're not looking at your data.

They can pull the curtain off anything you're running in their cloud, at any time they feel like it. It has to work this way for AWS to be of any use, and by using AWS you're implicitly trusting Amazon with your data.
