This is sick!
wintercharm··on My Experience at Apple
Hiring Newbies to call the shots becoming a cost saving pillar that eroded work culture at Boeing is one of those things that indirectly contributed to the recent debacle.
wintercharm··on A bunch of Covid-19 related mental health resources all in one place
The website Includes resources for:

1. Frontline Healthcare Workers (including access to remote counseling)

2. People who are grieving a loss due to COVID-19

3. People who need mental health resources during isolation

My content creation project (MultitalentFM) teamed up with Astra Labs (a youth-run 503c) to make this happen. From Pitch >> Launch was 1 week. Including myself, 6 people in 4 time zones worked on this day and night to get it together in time for launch.

We're going to be doing more in the coming weeks... stay tuned, stay safe, stay indoors <3

wintercharm··on The Apple iPhone 11, 11 Pro and 11 Pro Max Review: Performance, Battery, Camera
The scariest part of this is those Spec2006 scores.

A13 has single core performance on par with a 9900k or 3900X.

Apple is probably going to release ARM macs next year.

wintercharm··on The Apple iPhone 11, 11 Pro and 11 Pro Max Review: Performance, Battery, Camera
Yes, the article had a typo. I believe they've corrected it now.
wintercharm··on A Message about iOS Security
> iCloud has been hacked how many times now?

Zero.

Phishing exploits managed to get targeted users' passwords. thats what the Celebrity iCloud leak was all about.

wintercharm··on A Message about iOS Security
It is when they submitted the Apple releases to all these venues the day Apple's keynote invites dropped.
wintercharm··on A Message about iOS Security
China was also Conspicuously unmentioned in Google's / P0's original disclosure

:P

wintercharm··on A Message about iOS Security
I think the point being made here is why are both numbers not disclosed, and only one was?

I think both the time the bug existed and the relevant timeframe of known exploits should be part of a responsible security disclosure.

Omitting either one is a disservice to users.

wintercharm··on The iPhone XS and XS Max Review: Unveiling the Silicon Secrets
Those AVX instructions are quite costly though.
wintercharm··on The iPhone XS and XS Max Review: Unveiling the Silicon Secrets
I'd give it 2-3 years. They need to implement Marzipan fully, first.
wintercharm··on The iPhone XS and XS Max Review: Unveiling the Silicon Secrets
They also have a 192 instruction reorder buffer, and a really well optimized OS.
wintercharm··on The iPhone XS and XS Max Review: Unveiling the Silicon Secrets
Apple is going to have a good ecosystem of ARM software very soon. The whole reason they pushed their Marzipan initiative with the ability to seamlessly port iOS (ARM) apps to macOS (x86) is so that they can also do (iOS >>> macOS) on ARM.

By asking developers to port from iOS apps, they have the side effect of getting developers to implement "fully featured" apps, just with a mobile UI. Adobe has already promised they'll be doing this with photoshop and Illustrator, releasing in 2019.

Others will follow suit. Not only will this strengthen the feature set of iOS apps, but it will strengthen the iPad Pro app ecosystem, and apple will simply link the iOS and Mac App Stores, allowing for "universal" apps.

Marzipan will translate them to x86/64 and later when Apple switches to ARM, Marzipan will simply keep these apps on ARM, and change their UI to match.

If you've been watching Apple closely over the last few years, you'll notice that they're consolidating their API's across macS and iOS. Things like Metal and AppKit and UIKit and so on are beginning to converge. This is all setting the stage for Marzipan.

They announced the "first half" of what they intend during the WWDC 2018 keynote. But the second half will be announced only after they reveal ARM Macs, and then "surprise - all the iOS apps you see now are available here, too. They automagically get UI adaptations for mac!"

wintercharm··on The iPhone XS and XS Max Review: Unveiling the Silicon Secrets
SpecInt/FP is comparing Single core IPC between one A12 BIG core, and one Skylake server CPU core.

Per-core power consumption on that Intel chip is 165W/28cores = 5.89W

Apple is pushing similar IPC at 3W instead of 5.89W. In that context, it's not so unbelievable, and it's still really fucking impressive.

wintercharm··on The iPhone XS and XS Max Review: Unveiling the Silicon Secrets
You're correct.

Anandtech is using SpecInt/FP numbers to compare Single core IPC between one A12 BIG core, and one Skylake server CPU core. Per-core power consumption on that Intel chip is 165/28 = 5.89W.

Apple is pushing similar IPC at 3W instead of 5.89W In that context, it's not so unbelievable, but it's still really fucking impressive.

wintercharm··on The iPhone XS and XS Max Review: Unveiling the Silicon Secrets
Yeah. The S4 Apple watch SoC is actually using Two Tempest (LITTLE) cores.

Pretty awesome, if you think about It. That little watch is more powerful than it appears.

wintercharm··on The iPhone XS and XS Max Review: Unveiling the Silicon Secrets
Big takeaways:

- A12 has 8MB on chip “SoC cache”

- Big core L1$ = 128kB; Little Core L1$ = 32kB

- For the big core, L2$ is a whopping 128 instances 6MB per core/thread, 8MB at 64KB/inst.

- Little core L2$ is 32 instances, 1.5MB per core/thread, 2MB at 64KB/inst

- A12 GPU uses memory compression!

- A12 Big has 2.38 GHz base clock and 2.5 GHz 1 core boost

- A12 Little has 1.538 GHz all core, and 1.562 GHz 2 or 3 core boost, and 1.587Ghz 1 core boost

- A11 and A12 have a 7-wide decode (up from 6 on the A10) and 6Int ALU (up from 4 on the A10)

- Apple’s microarchitecture seems to far surpass anything else in terms of width, including desktop CPUs

- SPECint/fp Numbers show that it’s got 2x the speed of and any all other mobile SoC’s. 3x perf/watt if you normalize speed / power consumption.

- SPECint/fp numbers also show that the A12 is faster than a skylake server cpu (in core-for-core IPC). Not a perfect comparison, but far better than Geekbench

wintercharm··on Tesla delivered 83,500 vehicles in the third quarter, more than expected
Yeah, there's a clear shift coming in the automotive industry. The auto makers who don't have plans for electrification right now are in big trouble.

Thankfully, the VW group will actually be okay - they've tasked Porsche's engineers with electrification of all the companies owned by the group.

The Taycan will be built on the J1 platform (Porsche controlled/built). Porsche is developing 3 different packages for other car makers: the SPE (Sport platform electric) for Lamborghini, and then they’re developing a PPE (Premium Platform Electric) for Audi and Mercedes, and finally, they’ll have the MEB (modular electrification box) which is a kit for anyone else who wants electric drivetrains (VW, others)

wintercharm··on Apple’s 2019 Mac Pro will be shaped by workflows
The new iMac Pros are a good stopgap for pro users on the Apple platform.

They are nice machines with plenty of performance. With 4 Thudnerbolt ports, you have some expandability.

wintercharm··on Apple’s 2019 Mac Pro will be shaped by workflows
I remember those old Sun Blade processors. They were absolutely beastly, provided you had to know-how to extract parallel performance from them :D
wintercharm··on Apple Plans to Use Its Own Chips in Macs from 2020, Replacing Intel
Keep in mind that Apple has a veritable army of ARM developers (thanks to the iOS app store) which

1. doesn't suck 2. pays very well 3. has already demonstrated multiplatform apps with iPad / iPhone

wintercharm··on Apple Plans to Use Its Own Chips in Macs from 2020, Replacing Intel
> The MacOS ecosystem is both beautiful and deeply troubled.

So, shifting it to ARM and letting universal apps in the iOS App store now run on macOS in addition to iPad opens up the mac to a metric fuckton of developers that are happy to make cross-platform apps, since the iOS app store is SO lucrative.

Apple showed, with the iPad which was a totally new product category, that the sheer number of iOS developers could push the iPad from a platform with zero apps to the best tablet in the world (with an incredible app ecosystem) and universal apps who's UI adapt to the screen they're made for.

wintercharm··on Apple Plans to Use Its Own Chips in Macs from 2020, Replacing Intel
Apple claims the W2 chip is 50% more power efficient than existing Bluetooth/Wifi chips on the market, and is 85% faster than the W1 chip for data throughput.
wintercharm··on Apple Plans to Use Its Own Chips in Macs from 2020, Replacing Intel
Apple's watch now has a W2 chip that does Wifi and Bluetooth, and maybe even LTE (which is how they crammed it into such a tiny device).

Slowly but surely, they've put together all they'd need for a computer. Their T2 chips in the current iMac Pro handle encryption and NVME storage on the SSD's, as well as the camera image processing, Secure Enclave, and the SMC.

wintercharm··on Ask HN: I'm writing a book about white-collar drug use, including tech sector
Medical student here.

Used to drink tons of coffee. Sleep 4 hours a night, and micronap. Eventually realized that this was hurtin me long term when I found my memory becoming impaired. This only happened when I was in really intense study, so I feel like this thing won’t show for most people.

But I eventually changed my ways, stepped down from 4-6 cups a day to 1 cup in the morning, and I get 9.5 hours of sleep every night now.

I’m more productive, and healthier, and I know I can SUSTAIN this productivity. Sure, some of my classmates use adderall, others use cocaine... but I know that I’ll have better long term productivity and outlook than those people.

wintercharm··on “This Is Serious”: Facebook Begins Its Downward Spiral
This has been a long time coming. Facebook went too far, and they did finally push too hard. Creating divides is great for growth early on, but if you do nothing to repair the rifts you make, the structure cannot continue to stand.

His ruthlessness, and the change in facebook as it becomes something annoying and self serving, rather than serving the needs of its users who try to connect to each other. Facebook now charges pages to show stuff to users who've liked it - indicating that they ALREADY want to see things from that page.

This sort of extortionist double dipping is the kind of thing which ruins a social network. This, along with numerous privacy violations, ridiculous degrees of data mining, and more... good riddance.

That's incredibly creative, getting around the limitations of flip phones.
wintercharm··on FCC explains how net neutrality will be protected without net neutrality rules
Title II is a double edged sword, IMO.

Yes, it keeps NN agreements fair, but it also prevents expansion.

However, the ISP's are not to be trusted. They are not benevolent, and have already tried to mess up the internet for everyone.

I hope that the follow up to this is congressional rules (that are not so easily repealed) about broadband and how it must reach X amount of speed by Y date.

wintercharm··on FCC explains how net neutrality will be protected without net neutrality rules
This type of unrestrained capitalism creates monopolies that become unbreakable.

When the cost of entry is so high that laying cables is prohibitively expensive, it's almost impossible to compete with large cable companies to break their hold. Look at how much Google has struggled to roll out Fiber, due to all the complicated laws surrounding where and how you can lay these lines down in cities.

By forcing ISP's to maintain the fast lane, you could ensure that they would compete on fair terms, rather than just squeeze money from other corporations.
