Speaking as an engineer, it takes an engineer to get upset about people being upset for a slightly incorrect reason.
Yes however the continues incorrect labelling of the problem makes it trivial to ignore, if you continue too shout "parts lockdown anti-repair" and 9 times out of 10 you are technically wrong it very quickly make sit easy for those within apple to ignore. But if the reports were "apple is not providing tools to calibrate iPad screens" then that is something that can have track action were screaming the wrong thing is never going to have any impact at all.
As someone with engineer friends (in electrical, machanical and civil fields) I can confirm this is HAUNTINGLY accurate.
The reason is often more important that the specific issue
As an engineer I agree. It’s important to adequately interpret and thoroughly understand the problem to fix it.
Lmao this engineer completely agrees with you
calibration issues are when the colors are slightly different when you swap out a screen. The phone bricking when swapping out a screen is something else entirely.
1 is a fixable firmware miscalculation
another is an intentional software error
Exactly lmao this fool.. Also why tf does this shit not happen with any other phone company.. Just apple. Shill for Apple he is.

This is something I always tried to make sense of, complex products assembled in masses.
One thing however, usually failures that appear difficult to fix, comes to soldered on-board components failing/ or "calibration" and software, and as we know, soldered components are done by industrial level soldering stations, while humans are responsible for assembling the larger components, which is a repeated task that with practice, becomes monotonous but for external viewer, it might still appear as a higher-level skill.
Engineers aren’t included business decisions they’re just given justification. I am an engineer and no one has fully discussed the implications of what I am working on, but I am very aware.
so why don't engineers consider serviceability of their devices when they design them?

@@xenxander We do, and then we are told to completely change the design to something else that we didn't decide on and if we don't they get rid of us and get someone else who will
@@kasparsiricenko2240Sooo what he said.
Back in the day, using old Wacom pens and tablets, there was calibration settings for the pens built into the device drivers. You'd just go into settings, fire up the calibration software, the program would guide you over tapping a set of grid points on the screen and then calibrate a pen profile based on your inputs. Wacom used this to get over parallax issues they'd have, where moving the stylus to the edges of the screen resulted in poor accuracy due to the density of the sensor grid in those days.
It really doesn't matter to the end consumer what you call it, if calibration is the reason for poor operation, let them calibrate it then FFS.
That's like taking your car in for new tires, the guy puts the tires on and doesn't align them, then stares at you blankly when you ask him why the one side is wearing more than the other.
"You need an alignment dude"
No shit Sherlock, You're the one who's suppose to do that!
Maybe is not possible with the technology which Apple uses in the iPad or the iPhone (although the pen and sensors are manufactured by Wacom btw). But even in such cases, there are AMAZING repairers with Yt channels which can build substitutes for many of these "magic calibration tools" if they are given enough documentation how the process works.
But then you enter in the argument of "muh IP stealing", "think about the children, China will copy our designs" etc.
basically what he is saying is that what he designed was intended to have the calibration software built in, but some executive decided to not include it. then there is a big political movement to solve a problem that isn't the one that is causing them problems. it is how bad laws get made.
@@jamoecwCould calibrate the touch on your screen on plenty of older phones. There's no reason whatsoever colour and touch and input calibration isn't built into the software we have the technology we've had the technology for many decades.
@@bdhale34 exactly, which is why he isn't to blame. he thought the stuff would be included like it normally is. since calibration isn't pairing or repair in a technical sense it most likely won't get covered under the law and the problem won't get solved.
No you and I are not smart enough to tap dots that show up on an otherwise blank screen. Let the "trained professionals" handle it. It's a matter of national security.
When someone says "I'm sorry" or "oops" but keeps doing what they're apologizing for, it makes it harder and harder to believe they're being honest.
Here, let me make this easy for you.. When a Corp. tell you "I'm (we're) Sorry." It's a Lie, there's no test, you don't have to do Research, it's not a guessing game.. It's called "I will say anything for your Money." It's not fuckin Rocket Science.
Harder? At some point you’ve just got to stop believing them.
It's like having someone slap you in the face. How many times does it take before we start slapping back?
Calibration is one thing... Storing that data in locked down random locations and keeping the tools required a big secret is completely different.
There's no reason for angle sensor or backlight calibration data to be hidden away from repairers. Put it on a simple readable SPI flash chip with documented content layout (eg a known simple filesystem with actual files).
Or save the calibration data to a chip physically located in the part that it's for.... Like a normal engineer would.
The relevant components have no file system. And no protocol for normal transfers with main processor. And adding an external flash chip adds cost compared to having calibration data in the inside flash of the relevant microcontroller. Besides an extra component it may even require a larger microcontroller chip just to get more processor pins.
The product owners do not want to add extra manufacturing cost to solve a problem they do not have - they already have a working solution to perform calibration.
So don't complain about the hw, or about the engineers. Complain about the availability of the required tools.
The reason is to save money during production. If you put a small flash chip on each part and then during production calibrate each part then need to put that part through a chip progrmaign station that costs a LOT more per part (a few cent) than just reading the parts SN doing the calibration then saving the profile online agains the SN. Then having the SOC in diagnostic mode pull that profile from the server.
Why does an angle sensor need to be calibrated. It does not matter whether the screen is 2cm or 10cm open when it comes on. You can't see it either way.
@@alannitcher5001 it needs to be calibrated since there needs to be a known zero value to determine what opened by one degree or 5° is.
The last thing you want is the sensor to think the device is still open when you it and dust the screen staying on.
An uncalibrated sensor can be uncalibrated in both directions you could either not turn until you've opened the screen way too far open or never turn the screen off even when it's fully closed.
Why did apple go with an angle sensor over the previous simpler magnetic sensor? The reason is the same as the issue that some people have had with framework laptops recently where stacking the laptops can trigger the laptops do you think they are open as the magnets stacked devices interfere with each other, this drains battery.

Starting to sound familiar?
He's right about calibration being different from serialization, but this is still totally anti-repair because regardless of whether it's intentional or not, good repair is reliant on those calibration tools and if those aren't made available, independent repair is impossible, so not providing access to those tools is by definition anti-repair, since they wouldn't be losing anything as a result (other than profit from selling more new devices/having monopoly on their repair), no IP, no design details, just distribute a damn binary, but they won't, that's anti-repair, simple as that.
He is agreeig with you his point is that the anti repair isn't always on purpose. Sometimes a design can have that unintended effect. I think this is true although there are cases where it's deliberet. What he doesn't want is people to make shit bad about apple when there is plenty of truth to attack them. By making claims of evil it does give apple the defense of these people are slandering. If that makes sense.
It's intentionally bad design
@@Henrik229 it's apple, when has un/intentionally bad design stop them from keeping it as an anti-repair feature?
@@monsterhunter445Apple clearly intentionally designs their products to stop repair. You can make whatever bullshit engineering excuses you want. It still doesn't change the fact that someone at Apple is choosing to tell the underlings that their task is to design these products to encourage new purchases as soon as something minor goes wrong. I don't need to have insider knowledge to know for a fact that this is what has happened because the evidence we have clearly points to that being the case. The engineer is either intentionally being a corporate apologist for some reason or is so incapable of seeing this from a non engineering pov that he is making an ass of himself while defending bad faith practices. And saying "not giving out the calibration tools sucks" does not excuse the rest of what he said.
Yes, it's what's known as a "distinction without a difference".
As a software engineer I can honestly tell you that in regards to Errror 53, the (customer) support 100% talked to the engineering department to know why this error is happening.
Talking from experience those conversations typically go like this:
Support: Yo what is Error Code 53?
Software Engineer: That's a QA thing to avoid the wrong button being attached to the phone at assembly, why?
Support: Oh nothing, but thanks for clarifying.
Software Engineer: Well that was random, now on what ticket was I?
Support then get's asked by PR/Martketing what the issue is about so they can release a statement.
Support than says: Yeah the error happens when you attach the wrong button to the phone.
What PR/Marketing hears: You get this error when having the phone repaired with another home button.
And that's how this stuff is born 70%-80% of the time.
I had way too many conversations with Support and PR about those things....
This is why precise language is important. I now understand why they had us play telephone at school.
That example was so well done, its exactly how it went down.

Id have gotten the chair for what id have done in that situation.
I guess those hundreds of older iPads that I have replaced the screen on where the pencil continues to work flawlessly, even according to digital artists, must have been flukes. I am impressed just how many iPads came in perfectly calibrated on the older models by sheer coincidence.
"accept the fact that, for some of the stuff you want to do, you're never going to get OEM quality results."
Okay but that is only because of your companies shitty design and refusal to provide the tools necessary to get those results; the tools you guys created the need for in the first place! Like god dammit those types of gaslighting comments make me so mad.
The calibration data for the screens / pens were stored on the part itself in those older models. At some point, apple decided to move those calibration profiles to the mainboard because it would increase the difficulty of repair. Any cost savings argument is defunct because the parts in question STILL have to have a microprocessor on them to handle the serial communication with the main system.
@@trapfethen "because it would increase the difficulty of repair"
And that, right there is what should make the actions illegal, and the company heavily punished and held LIABLE for any Damage done if an indipendant repair person does a bad repair and fails to repair the device.
We should start holding the Manufacturers and Engineer designs Liable for their bad designs where the only reason they made the choice they did, was to make sure repairing was harder if not impossible.
Can you clarify which iPad generations are affected? I'm looking for a 9th gen to draw but after this video I need to re-consider.
@@user-bo4uc3el5t Sorry that I didn't see this until now. This Apple Pencil issue currently only happens with the iPad Air 5th gen, the iPad Pro 11" 3rd Gen, the iPad Pro 12.9" 5th and 6th Gen. This also only occurs during screen replacements in which you do not transfer the IC from the original screen.
Regarding you looking for an iPad to draw, I personally would recommend against the iPad 9. The main reason is that it doesn't use a laminated display, so there is going to be a physical air gap between the tip of your pencil and the screen itself. It will feel like you are never touching the screen and it messed with my digital art. The iPad Air 4th gen has been a pretty rock solid iPad in my experience, has laminated display, is not overly expensive for repair, uses USB-C and works with the 2nd gen Apple Pencils.
This calibration thing brings to mind my old nintendo DS i've replaced the screen to. it looked weird, but all i had to do was use the potentiometer on the back to calibrate the backlight, and it even asks for touchscreen calibration when i boot it back up.
Yes nintendo isn't the best company to take as an example, but the fact is the calibration tools have always been there and are incredibly easy to access when you replace parts. If nintendo did this 9 years ago, apple can also do it now
Your math is bad; Nintendo DS came out in winter 2004 and had user calibrated touchscreens
@@MarioMonte13 Damn forgot how old the DS actually is, i took the latest DS console release instead of the first, and i don't know how the calibration is on that one, my bad.

You think error 53 was really a bug?? Despite what Apple eventually acknoledged and said, I don't think there was a lack of internal communication. They knew exactly what was going on. Someone was tasked to write an iOS software update which gathered all internal serialized components to compare with a database and prevented booting if there was a mismatch. It was only the massive backlash which caused them to make this lame excuse and fix it...
They learned their lesson, error 53 was far too obvious. Now they do it sneakily like slightly perturbing the lines a bit when you draw.

It's weird how Apple's devices that aren't really different from any other computer has incredibly major calibration issues that can make a device painful to use if you even can turn it on, and those issues can't be fixed except by apple, while a majority of their competitor's devices don't
The main factor here is apple saving a small bit of money during manufacturing, most of the vendors write the calibration information to the part after calibrating it in the factory. apple in recent devices has chosen to save some money by calibrating it and saving that calibration information service side just using the part ID as look up for the value. This might save them one cent per component at most.
Apple devices and standard PCs are wildly different from an engineering standpoint. The Apple engineers working on Mac hardware have access to the entirety of the hardware/software stack for the whole device -- giving them the ability to fine tune calibration at a very low level in that stack (making it easier to individually calibrate each part to an extremely fine degree. PC hardware engineers get none of this. Every part of the hardware/software stack is made by a different vendor -- none of which share enough information with others to make highly calibrated device possible. So all calibration is done at the driver level -- which leads to the wonderful problem of Windows updates "breaking" your hardware, which leads to PC device engineers keeping things as simple as possible to avoid this, Which leads to those devices having hardware that's rather "meh" (I've rarely seen a Windows laptop with a trackpad that was any good, but Mac trackpads are great).
To quote Hector Martin in the same thread:
"Why doesn't this happen with other manufacturers?"
Two reasons:
- Apple cares more. Seriously, some of their engineering is unheard of elsewhere in the industry. And they have a specific focus on security that is miles ahead of everyone else.
- Apple is vertically integrated. They control their platform throughout and make engineering decisions that intertwine parts as a consequence, because it makes sense when they can do that for various engineering reasons. For example, their LED matrix backlights are controlled by an in-SoC microcontroller, and on M2s and above the trackpad touch processing algorithms also run in-SoC. This allows them, among other things, to ship those firmwares per-OS version and not have to bother with keeping backwards compat on the interfaces, which lets them move faster and improve more easily. Practically no other manufacturer does this to that extent, usually because they outsource complete sub-modules which naturally results in simpler dividing lines that then means easier part swaps. E.g. I bet any other platform doing LED matrix backlights will have the on-screen TCON handle that processing instead.

No apple is not going to spend extra money per part just to make repair harder that would cost them way way more than any lost revenue from repair.
They might be more complex to save money (even just 1cent per part). Eg moving calibration profiles to an online server that distributes them rather than loading them onto the parts chip saves a few seconds in the factory post calibration were they do not need to have a chip programming station to program the profile onto the part but rather just read the SN before calibration and use that in a online DB as the part ID.

Internal communication is for sure horrible at Apple. Called about a battery replacement in a Macbook. Support sent me to tech support, tech support sent me to engineering. Engineering agreed I needed a battery, sent me to a Apple store. Apple store (mind you a 5 hour drive to an apple store and back) said. "We don't do that". Well someone needs to tell everyone involved that you don't do that. I ended up spending 3 hours to swap the battery myself, involving a complete deconstruction of the device. But ever since, have had issues between the battery and the software. Not a big deal really in the end. But huge time suck trying to wade through the miscommunication and lack of shared information.

Edit: Xiaomi's _own website_ does in fact have a page to select your device and see a list of parts with their part numbers so you can find and buy them.
All I wish is that Apple would put at least a fraction of the effort they put into security (both user security and '''security''') into making it possible for third parties to correctly repair their devices.
That would require higher level management to dedicate time and effort from engineering teams.
@@hishnashThe only thing increasing repairability would change is Apple’s profit margins.
@@mrbanana6464 in the industry of silicon vendors and large silicon companies apple operates on the lower end of the profit margins. So I’m assuming you mean they should increase their profit margins to enable more repairability of their products?
@@hishnash Apple's profit margins are nearly 25%, they can absorb the cost. It's just that in classic capitalist fashion, Apple has found that making their devices less repairable increases profits because people are forced to buy Apple's new products instead of repair their old ones. Consumers and the environment be damned.
calibration for the backlight of the screen, should be in the screen.
calibration for a stylus should be stored in sensor or pen, and be in software/settings. (remember that old touch 4 crosshairs that dance around the screen on old phones and stuff?)
I’ve resubscribed recently and all I can say is wow what an amazing change to the channel as well as the outlook in life Lois has made. I’m very glad you left New York’s bs. I’m grateful that you continue to fight on behalf of right to repair. It seems like you’re more content in where you are in life now and wish nothing but the best for you! Keep up the good fight Mr. Rossmann
Normally, I'd buy the "calibration" argument as plausible, but let's face it: we're talking about apple here.
And yet it is calibration, and it almost always is calibration with apple. or firmware mismatch (apples teams make very tight assumptions about firmware versioning, they do not expect different versions of the firmware to be active on different parts of the system and they do not have any firmware downgrade systems)
We're talking about actually resonable reasons behind why Apple engineered these components that require calibration the way they did, and the Asahi Linux developer goes through all of the reasons in his post. Like how the trackpads between M1 and M2 MacBooks aren't swappable because the controller that controls the trackpad has been moved onto the main SoC die, enabling them to ship firmwares per OS version and not have to bother with "keeping backwards compatibility on the interfaces", which lets them move faster and improve more easily (and my semi-educated guess is probably operate the trackpad a little more efficiently since ICs separate from the main die are probably always less efficient).
I am going to have to call bs on his calibration. What he seems to be talking about is firmware on programmable logic. You can also program a device ID to the firmware to make the chip incomparable with any other device.
When you find a lie you know there are more lies to be found, this is not unexpected that someone would go too far, this is true everywhere, I am not surprised! Yet I do agree with you 100%, the question is how do you handle a liar, and tell people that liar is no longer lying!
the more one is on the scholarly end on the spectrum, the less they care about the outcome and more about the reasoning behind it. and sometimes, it is crucial to keep asking why before reaching the real answer.
1:42 Here's how this goes in my mind: if the backlight is uneven in the EXACT SAME WAY if you swap the displays of two machines around, that is intentional. If it was in different parts of the displays, then I would just say that it actually would need calibration.
"I was in Canadia" 0:06 🤣
There is no good reason for any of this unless your only aim is to fleece consumers.
well, there is one idea that might explain a bit how apple ticks: steve jobs always spoke about the devices being magic. and if the explanation about the functions of a device are hidden, the users will believe in the magic.
access to schematics, diagnostic tools, spare parts and the calibration tools obviously lift the curtain and allow a peak to see and understand the magic.
@@robertheinrich2994which is being maliciously used to support extortionate prices.

I love how this perfectly fits that old joke about being able to recognize an engineer. "Everything you told me is technically correct, but has no practical use to me."
"Conspiracy theory" isn't a phrase that anyone should take seriously.
If both Marcan and those he is adressing can not provide evidence of apple's design's goals being quality standard/maliciousness, then the evidence of prior maliciousness, which there is much of, is taken into account.
The fact that simply overwriting the serial number of a replacement display (& other components) using special tools works perfectly & consistently _completely_ invalidates claims like "Well, it's because you don't have special calibration data", "Apple's just looking out for you", etc. ALL I did was write a new serial number to it, and it works _perfectly_ now. In my opinion as an experienced computer technician, this just _is_ anti-consumer, anti-competitive behavior. Let's at least not pretend as though Apple hasn't set an abysmal precedent for bad behavior & victim-blaming.
Good video! Thanks, Louis.
As always, Louis, you keep the momentum going. I'm four months late in watching this, but it still feels like it was just yesterday. Cheers!
Louis, the battery pairing has no justification.
Also, the only brand on Earth which pair -say photo sensors and the processor - is Hasselblad. And they do it for a justified reason, the colour fidelity.
I don't believe a word...
sounds like a straight up QA issue then, if tolerances in manufacturing are such a moving target that Apple has to calibrate stuff after the fact, maybe they need to take that up with Foxconn
good point, like I have replaced a trackpad on many laptops and they all function and feel exactly the same
@@techguy348 I don't think Apple's doing things too atom-perfect considering with the Mini-LEDs for example 1 it'll still work but 2 it won't work well with a replacement, that doesn't say serialized for me cause they wouldn't waste time making it glitch out when they can put a block on it, that says that Apple is fu***ing stupid and incompetent
Mr. Rossmann, you're an inspiration to every up-and-coming EET professional, as well as well established EET professionals. The fact that you fight so hard for small businesses to maintain the ability to stay afloat in a very corporate lead field is admirable! Keep up the good fight!
I dunno, man. Apple kinda deserves all their dunks.
Pairing of parts and withholding calibration tools from users are two similar tactics to achieve the same result: Less iDevices get fixed, therefore Apple sells more new iDevices.
Yes but the solution is different, one is passing legislation that forbid serialisation the other is passing legislation that requires calibration tooling to be made public. if we keep on screaming serialisation then maybe some laws will be passed with respect to serialisation but they will not improve the situation at all. When the problem is calibration we should scream calibration not sterilisation.
Thanks Louis!
It is amazing just how bad internal communication is between departments. I am not an engineer but I work with engineers regularly to implement technical fixes to internal tools. There is a least once per week that something comes up because the engineers don’t listen to us, they did something that we didn’t ask for etc. I don’t believe that it is done maliciously for the most part, but it does get frustrating to see the amount of issues that could be resolved with better communication.
This comment is for Hector, but also for Louis - billion dollar companies do not deserve the benefit of the doubt, ever.
Serialization on its own is not calibration. It is artificial limitation that they could remove and part would work 100% the same. Calibration on the other hand helps to make parts/chips/whatever perform better in some way. So while there is possibly some merit that they do it for "security" for some parts, for other parts it just makes no sense and is purely artificial limitation and nothing else.
1:48 i swapped just the lcd on my A1706, the backlight is now stuck at full brightness, super annoying.
You don't understand that without calibration it's impossible to adjust the brightness 😂 funny because everyone can buy a cheap calibrator that would do a good enough job for such a bad display.
Other devices have that thing where you tap the crosshairs to recalibrate the screen
great to see you on top of things as ever, good vibes 👍
That engineer may be nerd smart but not consumer smart if he can't understand how increasingly anti-repair Apple devices have become.
Not understanding the full picture and blindly shooting conspiracies is not a very productive way of avocating for consumer rights though. And it's a great way to lose the support from engineers' side
@@miigon9117 What support from the engineering side? They work for the same party causing the problem by denying the ability to repair products, what support can we expect from them exactly?
he has a vested interest, its his paycheck talking rn.
@@nickstone1167 I don't mean apple engineers specifically. I mean the ones who has the knowledge and can help inform us and point us in a right direction.
@@nickstone1167 The best example is the engineer in the video, he pointed out that it's calibration and it's common engineering practice and actually has fair justification, so now we know to demand calibration tools and access to documentations, as well as better communication, instead of blindingly demanding apple to reverse the whole engineering decision altogether, which will be way harder to make happen and might lead to a worse product even if it ultimately happens.
Thing is, if the backlight aging data was stored on the display itself, uneven backlights wouldn't be a problem. Yet, it's stored somewhere else. Even if this is not deliberate anti-repair, it is something they can and should fix as soon as they release a new iteration.
You are absolutely correct and well-articulated points. Please keep up the good fight.
sometimes you state the obvious in such a wonderful way it gives me hope for the rest of humanity... then i watch a youtube short & im back where i started
youre my favorite guy-ranting-in-chair, louis & i love you for it ❤
Both of you are correct, but your more correct. The fact that someone got a detail wrong, does not negate the sentiment behind it. The reason for it not working is the same, Apple refusing to give the tools needed and making it impossible to work around. The secondary reason for calibration versus serialization really doesn't matter the primary reason is Apple?.
I was on a huge senior project as a storyboarder/background artist last year and ended up wearing down my apple pen tip to where the metal was bare. Bought non-Apple replacement tips and suddenly all my calibration issues/jitter dissapeared lmao
Great well thought out video. Open communication has always been the goal and that will not happen if everyone is pointing fingers.
Absolutely mind blowing speaking. Love and blessings.
Engineer here who tried to fight the corporate dross that some PR guy thought up...... And lost. Bottom line will always win over sense.
Imagine if projectors didn't come with keystone calibration tools built right into the firmware but you had to pay a certified technician from the manufacturer to calibrate it each time you moved it. lol
Calibration and SOT (select on test) are things I deal with in my trade so I believe the engineer. That procedure should be provided.
thanks Louis for your time and efforts
But, I can just swap parts on my Windows or Linux computers all "willy-nilly" and not have any problems. This includes my laptops, too. I have swapped screens, ram, batteries, hard drives, ssds, cpus, video cards, etc. And this is on both Windows and Linux, on both pcs and laptops. The only problem is if my bios wasn't up to date. And to be fair, I should be keeping that up to date anyway.
My ThinkPad went through a fair few changes in terms of hardware too and works perfectly fine, so does my desktop which is essentially the PC of Theseus.
I'm sure a open, modular, standardised system can't be compared to a tightly integrated system like for instance a Macbook, but they are both just freaking computers, there is no magic in there
I agree. The last phone I could change a battery was my Note4. I had that phone longer than any other, mostly because of the note7 recalls, I just decided to replace the battery and keep the note4. It worked great. I have an s23Ultra right now, and I think this will be my last Samsung for similar reasons.
Yes you can because they were well designed. Apple likes to think different. I recall my pocket-pc having a built-in screen calibration program back in 2002. We are taking engineering problems that have been solved decades ago.
You both have good points Louis. You always do, and you call yourself not smart but you have opened my mind to so many different ways of thinking and realizations. Thanks for everything that you do and stand for, it inspires lowly college idiots like me!!
I'm not an engineer, I have built some DIY tech and so for the fun of it, and yes, calibration is very often something that needs to be done.
IMU sensors need calibration, screens need calibration, touch panels need calibration, pen tablet/pen display need calibration, cameras need calibration, etc. Even in the DIY community you don't always notice it since some components are pre-calibrated from the factory.
In the DIY community, we often have ways to calibrate things, but when it comes to business, they often don't give the calibration tools, when really it would be better for them to give us the option to get a calibration tool for their devices.
Open communication is why I love the open source community, people are willing to learn from one another, help one another and support one another.
You make lots of really good points!
Great point we should definitely work together instead of turning against each other.
I think he has a point, but we have to admit that people with higher education have a habit of hating too hard. If you know its a complicated subject is it really fair to be so snobbish about peoples complaint. There's a reason anti intellecutism is on the rise and while a large part of it is outside our control, the one common element I see is smart people being snobbish with their super nuanced opinions, then being upset that people don't understand the nuance. Thank you for always trying to explain it without demeaning us who aren't in this field.
And even then, the dude is just being super arrogant and assertive about his stance on all of this without having all of the facts straight.
I respect you and him. Greatly,

Nothing worse than corporate simps
I don't think he is a simp at all and it makes me sad to read that. He's literally saying they should provide calibration tools to repair shops and consumers in his post.
Many of my mentors would challenge me to think outside of the box rather than accept an oversimplified narrative. Even when they weren't correct, it got me to think. They wanted me to think. It was a good exercise. I think that's what he's doing.
He's challenging us to think. Why else might this have been engineered this way? Because it sounds like he knows the people being asked to do this.
I'm happy and up for the challenge, and would love to have a conversation with him & people like him so i can learn more.
My goal with this video was not to throw shade, but give perspective as to why we assume the worst when repair shops get thrown under the bus in the name of security, because of Apple's prior history.
At the end of the day, for right to repair to succeed, we need _everyone_ on our side. That includes the top 1% of engineers that are responsible for our products being what they are.
@@rossmanngroupthose 1% engineers could not give a fuck, and if they did, they already sold it along with their souls
Billionaires and Corporations are not your friend, ever
He's not a complete simp...but I'd not contest partial simp. Maybe....20% real, 80% simp, mostly due to how frequently his employer lies. Guilty by association is mostly what I'd describe bc of just how many times the same actions have benefited the party that provides his bread and roof.
Yep. Corporate Slaves are annoying
Back in the days I could just plug a drawing tablet and it worked out of the box, and I could draw straight lines, and curved lines, and all sorts of other lines just like I wanted. No "pairing" or "calibration" was needed. So why is it suddenly needed now? :q
It was great to meet you at LTX Louis. Sorry my mind runs faster than my mouth. Sorry if I didn't make any sense talking about working on Navy stuff back in 1989.
Wow, that was powerful, Louis! 👏
So it's not just that Apple is incentivized to replace rather than fix their hardware, it sounds like they're also incentivized to be less transparent in cases like this, as any potential words they say that even acknowledge 3rd party repair or the existence of proprietary calibration tools could be used against them in future R2R lawsuits.
Like everything Apple, "Genius" is just marketing spin.
Something I realised a long time ago while listening to a keynote: The difference between cynycism/sarcasm and marketing is: tone.
Go read a transcript of Jobs back in the day. Read it with a cynical/sarcastic tone. "The most amazing, wonderful, fantastic, bigly, life-affirming phone evar". It's just tone.
I'm sure with the right phrase selection, pacing, and tone adjustment even Louis can sound like Jobs.
There's an old song's lyrics that might make you chuckle. They apply to the apple cult so well.
Cake: comfort eagle. "We are building a religion, a limited edition. We are widening the corridors and adding more lanes..."
Today's execs, like Jobs, merely know that there are plenty of spiritually empty sheep out there looking to have their minds and wallets guided. Best make it so they keep on spending and believing as much and as long as possible!
Side note, as this is about the way people were responding to this guy initially, not the actual points made but:
When people try to pull the whole “this is too much text to read therefore it’s a bad argument cuz it’s not concise!” it just really grinds my gears. Why? Let me translate what people really mean when they say this: “my ego is really fragile, so I’d rather pretend I’m not reading this statement for something silly like ‘iTs tOo lOng!’ rather than find out how I might be wrong!” Basically, it’s a cop out, and it always has been. It’s like when you get into an argument with someone and say “fine, let’s look it up!” And they then say “ I don’t need to cuz I know I’m right!” Well if that were actually the case, then looking it wouldn’t be a problem. It’s just something someone says when they’re trying to bullsh!t you. Every. Damn. Time.
Next thing you know Apple says it is not due to pairing, it is not due to calibration, internally we call it matchmaking
Doing literally fucking anything to an apple motherboard suddenly makes it not an apple motherboard?
I'd be throwing hands
Also we regularly make working shit with a couple billion pieces a few nanometres across, I think we can make touch screens behave with pens without some fancy chip
Personally? You're both right. Even though the engineer comes across bit as a simp for the product, the argument's solid, especially from his perspective. And same with yours. We simply need to force Apple's hand into releasing all required documentation to make these repairs feasible. I am tired of ever increasing effort I have to put into buying new hardware because the old brand started copying even more trash from crApple. Though I do find that fanboys deserve a bit of silencing, but that's probably spite talking. Thanks for the detailed introspection into both your and the engineer's point of view.
not providing calibration tools and having full control on the tools wich are necessary for the repair is in itself an antirepair act.
He comes across as angrily crossing his arms and yelling at people for not understanding that "it is what it is" when we all know it could be better.
3:42 Just your local overlord teleporting in to check on it's subject ensuring that it's well taken care of and doesn't get over stressed because of it's occupation.
Ok I dont know a thing about engeneering or techstuff. But I just wanted to tell you: you are such a likeable person! It's nice to listen to your voice and explanations and I totally support your opinion on apple. Thanks for dealing so friedly with such a sad and annoying topic.
Strange, but my LG V60 's screen is able to pair with ANY of the 6 dual-screen case displays, without any discrepancy in color or problems with the pen it supports on BOTH screens, no matter Where any were produced, as they were made in China as well as in Vietman.
Really, REALLY Strange....
Also strange is the fact that the LG V60 can be disassembled with a single size Phillips, and although I haven't taken mine apart yet (it's going strong even after 3 years of HEAVY use), I believe there's just a Single size screw throughout.
Truly unprofessional of LG ! Fortunately, not many i-Sheep have seen the V60 and its dual screen (which can be removed, or changed in seconds) nor need a headphone jack with hi-fi audio dac, and especially refused to even consider it since the v60 has that dangerous micro-sd slot supporting up to 1000 gb cards.
Must be really hard to talk with apple's dongle in this person's mouth.
Listening to Louis reminds me of the issue we were having with PDF files in a corporate environment. Out of nowhere, we'd have the users call in telling us that their PDFs had a display issue.
So we uninstalled and reinstalled. That fixed the problem.
And I thought "Well let's see if I have the problem in another profile on the same machine."
No.
So that led me to the user registry.
We started blowing away the registry tree for Adobe Acrobat, and relaunching rebuilt the tree afterwards, without the issue.
(Of course we backed it up to start with... but no adverse affects were found.)
And then I thought "What if we just have to get rid of one subtree?
After a few instances of trial-and-error, I narrowed it to a subtree...
...and then to a sub-subtree....
...and finally I was able to isolate the key.
Deleting that key (or setting it manually to the correct setting) resolved the issue.
So I'd had a good fifty or so of these, and my team in total had several hundred...
Why was the key being corrupted? I don't think we ever figured that out... but we took what was a 20-30 minute call minimum to reinstall the software, down to 2 minutes - remote registry connection, and fixing the key.
And thanks to the users who allowed me to perform trial-and-error to narrow it down... Some didn't want to give the time and would rather just get the software reinstalled.
But... hey... in the end it didn't matter... a bug fix was released by Adobe to fix it permanently.
(btw - all the internet sites had you reinstalling it... apparently nobody did the same and took the time to narrow it down.)
So I don't deal with hardware issues... but I've had enough software issues where you have to narrow down the cause, and find a solution, without any idea what you're looking for... Needle in a haystack... one component out of thousands... all would have been made simple with some guidance from the company.
Come on, Apple! DO BETTER!
I subscribe to so so soooo very few channels because I've never really liked the idea of it for various reasons but I have to give you some love. Not at all interested in repair, and only socially interested in right to repair. More than anything I appreciate the absolute shit out of your balanced nature. You always have this incredibly balanced and humble attitude in every aspect. Even when you're in a position to be intellectually superior you always maintain a friendly demeanor. You seem to have a very crystal clear, focused, and incredibly intentional handle on so many aspects in life that its entertaining in its own right. I watch your videos in the hopes that your balance brings my life balance, and I frequently find new balance that I suspect you don't even know you give off.

Installing Linux on a Mac shouldn't be so hard. But of course it is.
For a while I worked for a junky company down here in Mississippi. You probably even know the dude, years ago he came from the Bronx in New York, very possibly working around the corner from you.
Anyways, I have not only a tendency but even something of an obsession with organizing any shop I work for. I started from a junk pile of electronic crap and reorganized it all into a fully functional organized mess.
Well, he had so many junk parts already split up in different bins, all I could do was organize similar parts for related brands.
Somehow I became an expert in rebuilding the iPhone 5 and 6 during that timeframe (even including being able to distinguish that 1/2mm shorter trap screw out of the random screw bin).
On slow days I'd dig through their *completely* dismantled random phone parts, test out what does and doesn't work, and I managed to rebuild two *completely* functional iPhone 5 phones, complete with properly paired home buttons!
Anyways, thanks for coming to my Ted Talk, but yeah what the hell is up with all this parts pairing crap in the first place? And also why did my coworkers not know about this and just randomly gut the phones out?...
The post is also very confrontational and feels very emotionally charged. if you want to convince someone you walk alongside them, not confront them. While i understand what the post is trying to get across, many other people will end up feeling like they're being called dumb or feel belittled even though i'm sure that is not the intention of the original poster.
all that engineering and no one at apple thinks about making their own parts and firmware compatible and standardized so it's easier to calibrate and repair and potentially even easier to manufacture in the future
I don't buy this engineer's argument, unless engineers at apple are completely out of touch and don't understand the idea of standards and why they're important in any industry
they must be fucking allergic to making shit easy for themselves
No one thinks about it because it would cut into corporate profits. Corporations are legal persons that subsist on cash flow. Corporations dominate our civilization, not human beings. That’s why humans have to fight for any sense of control-because we are not in control anymore. Until corporations’ bottom line is not in conflict with human needs, nothing significant will change.
I just straight up don't get the "calibration" argument. Are they implying every single part in a device needs to manually have something calibrated to work? If so that is awful design and designed to fail. Like this argument is saying a single bit rot can destroy your system because god forbid something needs to self calibrate.
@@zombieguy The argument does not make sense because the engineer said what Apple wanted him to say, not the reality of the situation: Apple wants total control over every aspect of its ecosystem. Because profit > right to repair.
I'd say you are *not* an engineer. This is not NASA products. The goal is to keep down the manufacturing costs. "Standardised protocols" is an anti-pattern if it adds per-device manufacturing costs. As customer, you don't want to pay maybe $25 extra for silly overengineering. All you want is that it's possible to recalibrate. And the hw does support it.
So scream about access to the calibration tools. Not for arbitrary addition of extra costs.
Hector Martin has directly supported the censorship of the Internet.
In 2021, he claimed that Byuu (an emulator developer) had committed suicide because of a small thread on the Kiwi Farms. He provided no evidence to back this up and called for the Kiwi Farms to be removed from the Internet.
His posts resulted in a DDoS campaign against the site that continues to this day, one that has exposed many vulnerabilities in the framework of the Internet.
Louis, you're saying you're not smart when you've become a fairly successful RUclipsr, and have a talent with understanding machines on a level that many will never understand them.
Being smart isn't about instantly understanding every subject matter that drops into your lap, it's about how you use what you've got, whether it's physical or intangible, a skillset, etc.
Good video as always!
If the calibration for one part is stored in another and you cannot calibrate the new parts together, then that is no better than serialization and should be considered just the same.
That hector martin name seems oddly familiar. Didnt he organise a fake news campaign to get some website censored? Maybe I am mixing something up, but I remember the name and the profile pic of the DIP-IC.
Yeah, I think he was involved in the Cloudflare / KF debacle
Yes, he also lied about confirming the guy's suicide with Japanese police, his name hasn't shown up in the US foreign death's list to this day, so Hector deliberately helped the hoax.
I honestly think he has a point - he's trying to explain what the cause of this specific problem is, and he's frustrated at the idea that it's deliberate/malicious. Could the issue be avoided with a company culture focused on reparability? yes, and you have a point there - but not every decision is malicious by itself.
If you have engineers at Apple who think this was just happenstance and not malicious, and you tell your audience "hey this is malicious" - when they see the video, it's going to set them against you, they'll dig their heels in and resist everything you do, because they think you're treating them unfairly - so it can be a little counterproductive sometimes.
