Apple IS slowing down your old iPhone!

Source 1: posted by DrMacintosh https://linustechtips.com/main/topic/874983-apple-does-slow-down-your-iphonebut-its-not-what-you-think/

Source 2: https://finance.yahoo.com/news/yes-old-iphones-slow-down-not-think-210109678.html

 

  • iPhone users have noticed that their older phones are not performing as well as they did before iOS 10.2.1

  • but that performance increases after getting a new battery!

  • Apple is intentionally gating the the amount of power the CPU demands from the battery

  • This is because the phone will shut down to protect itself if the CPU demands more power than the battery can supply.

  • There are 3 common scenarios where batteries are less likely to be able to produce big bursts of power:

    • When they’re cold

    • Low battery

    • When the battery has degraded over time

  • Starting with iOS 10.2.1, max CPU power draw is stepped down in proportion to battery capability- it’s not just a binary “your battery is good or it isn’t”

  • This was originally applied to the iPhone SE, 6, has been applied to the iPhone 7 now, and 6S, and is planned for future devices.

  • Apple hasn’t made it easy to replace batteries

  • They could have bricked their phones up-front instead of bricking them a year after launch, but then they wouldn’t be as impressive and competitive at launch.

  • Are they doing the right thing? Are they going about it the right way?

  • 2 separate groups are now suing Apple

    • One claims Apple has done this in order to incentivize users to upgrade

    • The other says Apple breached an implied contract in which the company agreed not to intentionally interfere with their usage or the speed of the device, and also interfered with their personal property.

  • Universal Music Group will become the first major music company to license its recorded music and publishing catalogues for use on Facebook, Instagram and Oculus in a global, multi-year agreement.

  • Facebook has licensed the content for video and “other social experiences”.

  • The deal will:

    • allow users to post and share music on the social media network.

    • allow users to upload music in their video

    • "in time" users will also be able to access a "vast library" of music.

  • This addresses copyright issues raised by unauthorised use of its artists' material.

  • They’re are also working on products for Facebook's messaging service.

  • Facebook is also creating its own version of Content ID, YouTube’s service to identify rights holders’ content across its network.

  • Universal Music Group's executive vice president of digital strategy, Michael Nash said:

"Together, Facebook and UMG are creating a dynamic new model for collaboration between music companies and social platforms to advance the interests of recording artists and songwriters while enhancing the social experience of music for their fans."

  • Facebook has also been in talks with Warner Music Group and Sony Music Group

Source 1: https://www.bloomberg.com/news/articles/2017-12-20/magic-leap-shows-off-long-awaited-headset-with-few-details

Source 2: https://www.magicleap.com/

 

  • The Florida-based startup Magic Leap has long promised to develop a headset with technology that would show 3-D virtual objects superimposed on the real world,  by projecting light into the human eye—a simulation of how people perceive actual objects.

  • So far, Magic Leap has raised close to $2 billion and showed the public barely anything.

  • BUT on Wednesday morning the company updated its website to include photos of their “mixed reality” headset, the Magic Leap One.

  • The device includes

    • A pair of goggles with a vaguely steampunk aesthetic,

    • a controller

    • and a computing pack that you wear on your waist.

  • A software development kit will be available in early 2018.

  • Magic Leap counts Alibaba Group Holding Ltd. and Google among its investors.

  • “Shipping in 2018”

AMD confirms Q1 2018 release for Ryzen 2000 processors

Source 1: posted by JurunceNK https://linustechtips.com/main/topic/874920-amd-confirms-q1-2018-release-for-next-generation-ryzen-2000-series-processors/

Source 2: https://www.techpowerup.com/239659/amd-confirms-2nd-generation-ryzen-processors-to-debut-in-q1-2018

 

  • At a press event, AMD confirmed that its 2nd generation Ryzen desktop processors will debut in Q1-2018 (before April).

  • "2nd Generation" does not equal "Zen2" (a micro-architecture that succeeds "Zen").

  • 2nd Generation Ryzen processors are based on two silicons:

    • the 12 nm "Pinnacle Ridge" is a GPU-devoid silicon with up to eight CPU cores;

    • "Raven Ridge" is an APU combining up to 4 CPU cores with an iGPU based on the "Vega" graphics architecture.

    • The core CPU micro-architecture is still "Zen."

  • AMD is also launching a new generation of chipset, under the AMD 400-series

  • The second-generation Ryzen processors and APUs will carry the 2000-series model numbering, with clear differentiation between chips with iGPU and those without.

  • They’ll work on socket AM4 motherboards, including existing ones based on AMD 300-series chipset (requiring a BIOS update).

  • AMD is reserving "Zen2," the IPC-increasing successor of "Zen" for 2019.

    • The "Mattise" silicon will drive the multi-core CPU product-line, while the "Picasso" silicon will drive the APU line.

    • Both these chips will run on existing AM4 motherboards, as AMD plans to keep AM4 as its mainstream-desktop socket till 2020.


 

Seagate announces Multi Actuator technology

Source 1: posted by WMGroomAK https://linustechtips.com/main/topic/875233-multi-actuation-seagate-working-to-double-iops-on-spinning-disks/

Source 2: https://blog.seagate.com/enterprises/multi-actuator-technology-a-new-performance-breakthrough/

 

  • Seagate says that boosting hard drive capacity is only half the battle: fast data access needs to keep pace.

  • Hard drives today are equipped with a single actuator, which moves all the read-write heads together in synchronous motion- but Seagate is adding more.

  • In its first generation, Seagate’s Multi Actuator technology will equip hard drives with two independently operating actuators.

  • This enables a hard drive to double its performance while maintaining the same capacity as that of a single actuator drive.

    • “Basically, we’re taking the high-capacity hard drive a customer already needs and expects, and magically doubling the IOPS the customer gets from it — with no down side,”

  • This technology can be used alongside other emerging tech like HAMR

  • The technology is “in development to be deployed on products in the near future.”

Source 2: https://www.theverge.com/2017/12/21/16804992/microsoft-windows-10-windows-hello-bypass-security

 

  • Windows Hello, the face scanning security feature of Windows 10, has been defeated with the use of a printed out picture.

  • The picture was a 340x340 print out of the authenticated user’s face, taken with an infrared camera

  • Who’s vulnerable?

    • Machines running (various) older versions of Windows 10

    • Updated machines that don’t support Window’s anti-spoofing feature.

    • Updated machines with anti-spoofing is enabled, where Windows Hello was sey up on an older version of Windows 10 (like the Anniversary Update last year)

  • Fix:

    • Update to the latest version of Windows

    • Enable anti-spoof if possible

    • Re-initialize Windows Hello

  • Codenamed “Marzipan,” the secret project is planned as a multiyear effort that may be announced at the company’s annual developers conference this summer.

  • With a single app for all machines, Mac, iPad and iPhone users will get new features and updates at the same time.

    • Right now, the iOS Twitter app is regularly updated with the latest features, while the Mac version hasn’t been refreshed recently and is widely considered substandard.

  • It’s unclear if Apple plans to merge the separate Mac and iOS App Stores as well

  • The difference between an iPad Pro and Macbook just got even smaller.

3D Printed Objects that Connect to Wi-Fi without Electronics

Source 1: posted by PeterT https://linustechtips.com/main/topic/875799-3d-printed-objects-that-connect-to-wi-fi-without-electronics/

Source 2: https://www.element14.com/community/groups/power-management/blog/2017/12/07/researchers-3d-print-first-objects-that-connect-to-wi-fi-without-electronics

 

  • Researchers from the University of Washington have developed the first 3D printed plastic objects that are capable of collecting and communicating data wirelessly without any electronics or batteries.

  • The device is made of 3D printed gears, a spring, and a switch made of conductive plastic

  • How it works:

    • The device will reflect back signals that are emitted by a Wi-Fi router

    • But before they’re reflected, the signals will be encoded with data.

    • 3D printed gears, springs, and switches translate motion into information

    • The physical motion causes the springs and gears to engage a conductive switch to intermittently connect or disconnect with the embedded antenna, changing its reflective state into 1’s and 0’s, thereby encoding data into that signal.

  • The team demonstrated their new system using several 3D printed tools,

    • a flow meter to keep tabs on liquid laundry soap,

    • an anemometer that measures wind speed

    • several widgets (a button, knob and slider) that can interact with other smart devices to manipulate things like music volume, lighting and object weight.

  • The researchers are making their CAD models available to the public

Few corrections about stuff said during the wan show:

 

1) "heat is bad for batteries"

No, not always. "too much" heat is bad, but moderate heat is good because it helps the electrical energy to chemical energy conversion happen faster.

Batteries can charge and discharge at higher C rates when at higher temps (like 30C-40C) compared to ambient.

When you get to sub-0C then things start getting very bad for the charge and discharge rates.

Image result for lipo battery discharge rate vs temperature

 

2) "trickle charging"

Neither wireless chargers nor regular cable chargers trickle charge.

All manufacturers are aware that you NEVER trickle charge lithium batteries, and all modern phones and laptops will stop charging the battery completely when it is full, even when left on the charger.

The circuitry in the phone or laptop will only start charging the battery again if it drops below a certain voltage.

Papa Linus I will address some concerns.

 

1) 6S was added in support with the 6 and SE.

2) It will be planned for future devices as they age (Some people might wonder why the 7 was not added when the feature was introduced). Your thinking is also flawed in thinking that Apple plan to make phones unuseable. They do not. Battery life has been a forefront of Apple for a while and this is (and has been) expected.

3) Batteries are replacable by an Apple Authorised Servicer, they are relatively as replaceable as should be for a phone like this. Keep in mind the design of the phones - and their age of affected phones. Apple batteries should NOT be user replaceble and should only be replaced by the Authorised Servicer.

4) I'm saving this spot for the bricking I'm not sure what you mean now so I will edit when I see this segment. [EDIT] This must have been a typo in the WAN show doc because it is just not true at all.

5) When you say you think Apple will not suspect anyone to benchmark it - thats how this was discovered.

 

To address the utterly stupid lawsuits:

- Apple has actually increased longevity with devices before. This is in no way to force you to upgrade. If a replaceable battery (which is a simple fix) is the issue - and the phone will work perfectly fine after, then this  lawsuit does not have any merit whatsoever. Also to note; the 6 and newer models of the iPhone, to which the update only addresses, are not old phones. They will continue to be supported.

 

- Apple have made many adjustments to the performance of devices like this, through updates - even the clockspeeds of the chip. The term, 'Implied Contract' just screams a lot of BS. This lawsuit is baloney.

I'm halfway through the youtube upload And, Done and it's the best WAN show in ages xD However kinda short, no break 4 u ^_^ Just kidding, tho a santa hat on the characters would of been nice :P

 

But, ummm @LinusTech about Luke leaving he doesn't need to "quit" on the ROE you might be able to put K in block 16 then in Block 18 state something like Employment transferred to Floatplane or something like that. He's not quitting to go to a new job, he's being acquired via separation of companies :P

 

Dont quote me on it but i dont think there's any need to put quit or anything negative in that sense on any paper. Legal or not.

I'm not the most well educated in this, but would it be viable to have Floatplane be a subsidiary under LMG? I assume it's already been considered and shot down, but I'd love if someone more well-informed could tell me why :P

Also, nested comments for Floatplane (sort of like Reddit)? Allows for replies and more discussion, which can't be bad, right?

As a small-time creator, how will Floatplane work?
I must've been under a rock the last couple months cause I know nothing about it.
Will it be a subscription-only service when it fully launches?

Easy, think Target Canada. Not much different here, they are trying to do something that is already readily available to the market (the internet).

 

Why would this make a difference? Because if Floatplane becomes too big too fast and fails, or simply can't make money and fails that way (like Target Canada), the debtors can't collect from LMG or Linus (who then could liquidate/sell LMG to repay) which as long as Linus didn't personally sign on to any of the debt Floatplane might or does have (think Linus as a guarantor if he did).

 

Now the good news.

Because this is happening unless plans where already drawn out for it to happen on Jan 1 2018  (the business plan, if they sought investors, generally as a rule good to have one not matter what), it means Floatplane is or will be breaking even and has the future outlook of breaking even or profitable in the next year.

 

And the Profitable news for LMG.

Because Floatplane is going to be subleasing this brings in an additional income source for LMG, chances are it's room already not being used or already being used which if Linus tossed Floatplane out would become not used. So basically LMG will be renting space out they won't be using to bring in money (hence subleasing), if Linus is paying $5 sqft and leases to Floatplane for $7.5 sqft thats $2.5 profit and he likely will charge out a % of the monthly utilities and condo fees to Floatplane as well, making LMG cheaper to run.

 

Now if Floatplane fails and can't pay rent there might be a way of turning some or all of that $7.5 sqft (along with the % outlined) into a tax credit, now don't quote me on that as every province is different and every situation is different too.

 

But I wish Floatplane all the best and a profitable 2018

He has endless amounts of phones sent to him on an annual basis, I don't get it.

Not all of them are keeper units

 

 

@LinusTech are you still going to be CEO of both LMG and FPM?
