Interesting to see his take on “e-mail” vs “email”. I bet he changes his tune on “email” vs “mail” -- where gen-z has decided that it’s okay to save keystrokes by dropping the “e” because no one uses snail mail anymore. Indeed I am always disguested when someone says “send a mail”. I have to ask for clarification and they always confirm that mean email.
Do you mean the USB PD spec? It does not violate the USB spec which sets a default voltage of 5v. The adapter /might/ violate the USB PD spec if it were to claim to be PD compliant. But the shit-show we have is that USB-C does not imply USB PD. And so the market is full of USB-C things that are not USB PD. Often they do not claim to be USB PD as consumers are not wise enough to demand it. AFAICT, USB-C devices that do not mention USB PD would stand up in court.
Note as well the adapter I mentioned is quite dumb -- just hardwires pins for the situation that the appliance expects 5v without negotiation. Naive consumers could get burnt for sure whenever exceeding 5v.
But it would be possible to implement a USB PD-compliant adaptor with the smarts to handshake, which would then refuse to complete the handshake in the event that the voltage supplied is not that requested. Of course it would be a bit strange to put that much sophistication into it which I suppose would drive the cost to that of a whole compliant PSU anyway (thus defeating the purpose). But notice the opposite has been done in a compliant manner, whereby the barrel adapter negotiates a USB voltage on behalf of a barrel device.
as there’s no way to communcate requirements through the barrel.
IIRC, it’s disputed whether the hanshake negotiation is needed for 5v. Some appliances expect to do a handshake /no matter what/, and some 5v appliances are designed to skip the negotiation entirely. If you are in the camp that says even 5v must have a handshake negotiation, then you would condemn the simple barrel to usb-c adapter (but perhaps not one that is only for a fixed input and the circuitry to do the negotiation).
Hard to blame USB for when we side-step it’s design.
The blame was not pin-pointed. I pointed out a shit show in the marketplace. There are bits of the standard you can blame (ambiguity and also having optional voltage steps), and you can also blame market actors. You can probably also blame regulators for not preventing the shit show that I described. And perhaps even blame consumers for not insisting that what they buy is tagged as USB PD complaint.
Which shows those USB PD negotiations can get dicey. It chooses voltages thought to be close enough to what’s requested.
I’ve run into a nasty problem where a USB-C appliance needed 9v. Says in the manual something like “only use Kenwood power supplies on this device”. I thought, fuck that, USB PD is a standard for a reason. I’m not going to blow money on a proprietary OEM Kenwood USB-C PSU. Then found that many power supplies actually skip 9v. The USB PD standard makes some voltage steps optional, and some mandatory. IIRC, 9v was one of the required ones, yet it was easy to find USB-C power supplies that skipped 9v but offered 12v (or 15v, I forget). And yet 12v or 15v was one of the voltage steps that’s optional. And IIRC, the Kenwood OEM PSU /only/ did 9v, which is also not USB PD compliant, so the Kenwood PSU could not be used on other things.
So the USB PD strangely and arbitrarily makes some voltage steps optional, and manufacturers ignore the standard anyway.
I have an adapter that goes from barrel to USB-C. Recipe for disaster. Even if a 9v PSU uses that adapter and a USB-C appliance wants 9v, it will fry shit because any non-5v appliance expects to negotiate the voltage. I don’t recall how it leads to frying (I think b/c it tries to start at the 5v default before negotiating for 9v but instead it just gets hit with 9v), but the fact that there are USB-C-barrel adapters that just hardwire without the needed logic is scary.
So in the context of copious dumb users plugging in anything that fits the socket, the data PIN may¹ have prevented a lot of damage while at the same time enabled HP to rack in lots of money on replacement OEM proprietary PSUs. Indeed I have seen on many occasians clueless plebs at the street market selling 2nd-hand appliances and quickly trying barrels from a pile of tangled PSUs until one fits, then trying to include that with the device they are selling without looking at voltage or anything. It’s common and I’m sure lots of gear gets fried because the general population is just not smart enough.
I know how to match voltage, polarity, and current demands. And I got stung by the nannying to protect me from myself. Spent a lot of time disassembling a laptop, trying different RAM sticks, removing wifi cards and other components as I was baffled about what this fucking blicking LED means when it is not blinking in any way to convey an error code. Removed the CR2032 battery to reset the CMOS. Wondered if my slower than spec DDR3 RAM was causing this, so I went to the trouble of tracking down a RAM stick the precisely matched the specs. Still just got a steady non-stop blink, which the manual falsely states means it’s in sleep mode. So I was ready to conclude that the laptop was trapped in sleep mode and irreparably hosed. Perhaps I would have tossed a working laptop.
Whether it is a good design to protect from incorrect PSUs (despite that the obscure barrel connector is probably only 19.5v systems anyway), most certainly it’s a crappy design to not inform users. To fail to assign an error code. Sure, it vaguely says in the manual something like “use only approved HP power adapters” -- something /smart/ consumers do not take seriously because they know how to match PSUs to appliance and know that shit is always a branding hussle. The data pin should not be a secret that is concealed from both the user guide and the maintenance and service guide (which HP says is not for end users.. yet they still withhold the info from service people).
Perhaps good design as far as the PSU goes. But shitty to not document the situation and to not implement an error code.
¹ I stress /may have/ prevented damage because I have seen a lot of street market goods and only seen this obscure barrel tip on HP and Dell laptops, both of which are 19.5v.
AT&T is the worst of the worst. And I boycott them for countless reasons like snooping on their own customers voluntarily without a warrant. It’s really a hard-right corp. In any case, never tried them so I didn’t know they blocked egress 25.
One trick that works if truth-in-advertising laws are in force: ask the sales people before subscribing if the block port 25. They always say “no, we block nothing” (in my experience). So you subscribe and sign the contract. Then when you see they actually block 25, you have a false advertising situation and also a contract violation (if either verbal contracts are enforcable or if you can get it in writing that nothing is blocked). So you complain. In my experience, they give a gratis upgrade to an enterprise level of service that generally has a static IP and no blocks -- for the price of the residential plan you signed up for.
Ok, thanks for the insight! I thought the center pin would be positive and the barrel exterior would be negative. But when I look closer at the Dell tip, it has two cylinder contacts plus the pin. And on the HP socket there are apparently 3 pins. Really hard to see the metal on the inside cylinder but I think it’s there.
What a mess. Now I need to know how to spot the correct PSU when I’m at the street market. I take it from your experience that it’s not enough to be HP with correct V and A. It must also be 3 conductor. But will that be enough, or might some be model-specific?
I have seen some universal chargers with 3 pins. I assumed the 3rd pin was so the tip could indicate to the PSU which voltage to switch to. Now I have to wonder if that also caters for HP or not.
I can’t speak for @ShutUpWesley@piefed.zip, but I boycott both Google and Microsoft. This means 95+% of prospective people, corps, and gov agencies I would exchange email with are not getting email from me. They are also not getting an email address out of me.
I have been done with email for nearly a decade now, mostly. So, to answer your question, I use fax and snail mail. Not joking. I feel liberated and don’t give a shit about postage or inconvenience. There is still that exceptional 5% or so who I will exchange email with, which does not have GAFAM in the loop.
(edit) should add that I give friends and family an XMPP address (of my own, but often I also give them an XMPP acct for themselves). Google bounced from XMPP a decade or so ago and AFAIK Microsoft has no XMPP service. So it’s mostly snail mail and fax for govs and corps. XMPP for people.
Any friends or family who resist XMPP are mostly stuffed. They can either proxy through a mutual friend or call me if they are local.
Maybe the way to fight GMail’s outsized power is to stop using GMail.
Stopping your own gmail use is trivially easy. It just scratches the surface. In order to not lick Google’s boots, you also need to stop sending email to gmail users. That means doing an MX lookup before emailing to see if their vanity email address is on a Gmail host. And of course this also means not sharing an email address with gmail users.
I do that, in fact. I also boycott Microsoft. In the end, this means I am not using email much at all.
Very happy to have learned about tildeverse.org. It gives a great refuge from a lot of the garbage. But I have to ask, if you are part of the tildeverse project why are you on lemmy.world, a centralised exclusive Cloudflare instance? I realise tildeverse does not have a lemmy node but there are many decent ones and LW is probably the most contrary to the tildeverse philosophies.
I use the stock Lemmy client -- and that’s unrelated. The problem is you have chosen a centralised walled-garden (lemmy world) for your instance. You should switch to a less oppressive instance. This gives some background on Cloudflare:
This definitely smells like a power problem, but we haven’t eliminated that your Dell PSU is actually fully functional yet, have we?
The Dell PSU has a white LED built into the cable end showing there is power -- a rare feature. That LED lights up with good brightness so I did not initially question the PSU. I just now attached a DMM which measured 300 mV. Another DMM measured 100 mV. So indeed the Dell PSU is bad.
Kind of a shame the LED is not designed to light up when ~19.5V is detected. I guess that might increase the cost too much.
Is your Dell PSU able to power up any other laptop successfully (with that laptop’s battery removed)?
I never used the Dell PSU before and have no other appliance for it. I happened to receive it along with other 2nd-hand stuff I bought. Thought I was lucky to have it once I came home with a laptop that needed it. None of my universal PSUs do 19.5v.. just whole numbers 19, 20, 21, etc.
Thanks for your feedback. Not sure how much longer I would have fiddled before deciding the test the PSU.
(edit) Now after insight from @over_clox@lemmy.world, I don’t know if the Dell PSU is broken. Perhaps the 3rd conductor which is used for data (to indicate brand-loyalty) is failing a negotiation. I wonder if it would send 19.5v if plugged into a Dell laptop.
(edit 2) correction- This diagram for HP’s connector is apparently the same as that of Dell. So my measurements (100—300 mV) were bad. Metering the outer and inner cylinder yield 20v using a cheap DMM and no load. So the Dell PSU works and is likely sufficient in terms of physics.
OP, for at least the past decade, both HP and Dell have their own data sense pin, to declare brand, voltage and amperage.
I appreciate the info. I’ll keep that in mind when looking for a replacement. I could only hope my problem is that simple but I don’t suppose that could be my issue because the HP probook 645 g1 is from 2013 or early 2014. It looks like a barrel connector with 2 pins.
shit.. lemmy.world is in cloudflare’s walled garden so I cannot visit that link because I am excluded from their perverted idea of what constitutes a legitimate human being.. like I am undocumented trying to enter a right-wing restricted country. Is there a free-world cached version of whatever comment you are referring to that you can link for the general public?
The Dell PSU I am using is 19.5v 3.34A. The reqs on the HP sticker are 19.5v 3.33A. I suppose that’s an exact match.. probably a question of whether they round up or truncate 3⅓A. I could buy an OEM HP PSU. On the big street market I go to it will be cheap enough, like 2 dollars. OTOH, I’ll be surprised if it makes a difference. I will just be wasting 2 dollars, I suspect.
Doesn’t stop it broadcasting, but stops it being useful to anything nearby.
Any SSID broadcast is useful to Google and Apple spies (read: simple phone patrons) who feed the SSID to the mothership which is then used for mapping. There are security risks by that alone even if it’s blocked from my LAN, which I detail in these threads:
Apart from tracking my residency, I boycott both Google and Apple, so I object to feeding them in the slightest even when it’s innocuous to me. The map data enhances their location products and feeds their advertising surviellance machines.
Anyway, I appreciate your insight. I assumed it was a proactive act by Karcher and would not have thought that they were naive or lazy w.r.t. something baked-in upstream from them.
You’re likening the ability of apple/Google to see devices moving around in Ukraine to someone figuring out who you are because you have a DAB radio transmitting an SSID and a MAC address - that only people within a hundred or so metres can see.
Of course. Apple does not distinguish a DAB radio from a smartphone from an access point. It just blindly collects all SSIDs and MACs. Why do you think a soldier in Ukraine would get not only different treatment, but in fact more compromising treatment? That’s absurdly unrealistic. It costs Apple money to pay engineers to write tailored code and filters that then get deployed to all iOS devices at the risk of the exceptional logic doing the wrong thing. Of course iOS devices indiscriminantly send all data just the same.
The Ukraine soldier tracking was a scandalous embarrassment, so it stands to reason that adjustments have been made since then -- and most likely by Ukraine not Apple. But if it were Apple, the change would obviously be to /not/ collect the compromising data of soldiers. A war fighter has a higher expectation for privacy than a DAB radio listener.
It’s not Apple who tracked the Ukrainian soldiers. The exploit was demonstrated by an end user who was simply making use of available data from Apple. IOW, some avg. Joe tinkering in their basement could do it. And they could do it with LESS information to start with. The person who demonstrated the tracking was much further than 100 meters. They were not even in Ukraine IIRC. They did not know where the soldiers were to begin with (IIRC). Unlike a Karcher scenario, where an adversary could very well have the victim’s starting location. It’s trivial track the victim from there in this case.
Again, I bring you back to the test laid out by the EDPB. For indirect identifiers like this to be considered personal data you have to consider the technical ability and the liklihood of someone converting that indirect identifier into something that actually identifies you as a natural person.
Do stalker victims have to prove the likelihood that their threat agent will attack? It’s already clear to me that the GDPR is mostly a failure. If judges and GDPR practitioners were to require proof that excessive data would likely lead to misuse as a precondition to corrective action against art.5-1(c) infringements, it would be yet another failure of the GDPR. The whole point to Art.5-1(c) (data minimisation) is to improve privacy generally without anticipation of particular threats. That’s the whole point of it. What you suggest is a purpose-defeating abuse of interpretation and discretion.
But in the real world, I don’t believe you do. You mention a stalker - a stalker isn’t going to find you by driving around using a WiFi scanner looking for a DAB radio.
If I ever have a stalker, I hope they are as unmotivated and undevoted as you suggest. But I have to say you have a strangely optimistic or flippant view of the psychology of a stalker.
Others? You mean the person who thinks data is only collected by product registrations? Who thinks “smart” devices have no GDPR relevance? And who thinks MAC addresses are not unique and who also thinks a MAC address on a DAB radio can be changed by consumers apparently without breaking an anti-reverse engineering terms of use? Who also thinks Karcher would become GDPR compliant through a MAC changing mechanism if it were to exist. Who then tried to establish credibility by claiming to endorse the GDPR. Indeed.. not a good source.
unless you registered it under your name then its MAC is not linked to you.
You cannot really know what Google and Apple do with their data collection as opaque as they are. But the data is there. They have enough to link people to MAC addresses on a large scale in an automated fashion. The data collection is proven by Douglas Leith’s research.
At the same time, we need not rely on assumptions. I could unwittingly place my Karcher within view of my front window while my neighbors who know exactly who I am. I might also be the sole person in hundreds of meters who has a Karcher that emits a unique MAC address. Any arbitrary owner of a Karcher radio would not necessarily even be aware of the reckless emissions. My neighbor would realistically have a great degree of certainty that the MAC address relates to me as they can see the signal strength increase ast they approach my dwelling and decrease as they walk away from it.
To make this more interesting, replace “neighbor” with “stalker” in the above paragraph. Then when I move to get away from the stalker, the DBs of Apple or Google could reveal¹ my new location. Or the stalker can war drive if they know I didn’t move far.
¹ Note that research showed that Ukranian troops were trackable using Apple’s map tool that all ordinary Apple consumers have access to.
Once again “personal data.” You haven’t told us how Karcher knows that the device belongs to you. Everything else is irrelevant.
Nonsense. Karcher doesn’t need to know /who/ the personal data belongs to in order to be accountable for designs that violate Art.25.
Local storage is subject to GDPR if: The organization maintains control … The data is personal
Did you log on the device using an email or any personal data? You have to consult a lawyer for that because I doubt you fall in that case.
wtf, stop making up quotes.
A MAC address is unique
Absolutely not, and it can be changed.
Citation needed. Karcher does not even allow users basic access to change the SSID. Please point to the page in the Karcher user guide showing how to change the MAC address on their appliance.
Interesting to see his take on “e-mail” vs “email”. I bet he changes his tune on “email” vs “mail” -- where gen-z has decided that it’s okay to save keystrokes by dropping the “e” because no one uses snail mail anymore.

European ISPs block egress port 25, not American ones, generally. Not sure about the rest of the world.
In Europe, one refuge is to send using the GSM networks, which tend not to block egress 25 for some reason.

Joe tinkering in their basement could do it. And they could do it with LESS information to start with. The person who demonstrated the tracking was much further than 100 meters. They were not even in Ukraine IIRC. They did not know where the soldiers were to begin with (IIRC). Unlike a Karcher scenario, where an adversary could very well have the victim’s starting location. It’s trivial track the victim from there in this case.
Do stalker victims have to prove the likelihood that their threat agent will attack? It’s already clear to me that the GDPR is mostly a failure. If judges and GDPR practitioners were to require proof that excessive data would likely lead to misuse as a precondition to corrective action against art.5-1(c) infringements, it would be yet another failure of the GDPR. The whole point to Art.5-1(c) (data minimisation) is to improve privacy generally without anticipation of particular threats. That’s the whole point of it. What you suggest is a purpose-defeating abuse of interpretation and discretion.
If I ever have a stalker, I hope they are as unmotivated and undevoted as you suggest. But I have to say you have a strangely optimistic or flippant view of the psychology of a stalker.
Others? You mean the person who thinks data is only collected by product registrations? Who thinks “smart” devices have no GDPR relevance? And who thinks MAC addresses are not unique and who also thinks a MAC address on a DAB radio can be changed by consumers apparently without breaking an anti-reverse engineering terms of use? Who also thinks Karcher would become GDPR compliant through a MAC changing mechanism if it were to exist. Who then tried to establish credibility by claiming to endorse the GDPR. Indeed.. not a good source.
You cannot really know what Google and Apple do with their data collection as opaque as they are. But the data is there. They have enough to link people to MAC addresses on a large scale in an automated fashion. The data collection is proven by Douglas Leith’s research.
At the same time, we need not rely on assumptions. I could unwittingly place my Karcher within view of my front window while my neighbors who know exactly who I am. I might also be the sole person in hundreds of meters who has a Karcher that emits a unique MAC address. Any arbitrary owner of a Karcher radio would not necessarily even be aware of the reckless emissions. My neighbor would realistically have a great degree of certainty that the MAC address relates to me as they can see the signal strength increase ast they approach my dwelling and decrease as they walk away from it.
To make this more interesting, replace “neighbor” with “stalker” in the above paragraph. Then when I move to get away from the stalker, the DBs of Apple or Google could reveal¹ my new location. Or the stalker can war drive if they know I didn’t move far.
¹ Note that research showed that Ukranian troops were trackable using Apple’s map tool that all ordinary Apple consumers have access to.
Nonsense. Karcher doesn’t need to know /who/ the personal data belongs to in order to be accountable for designs that violate Art.25.
wtf, stop making up quotes.
Citation needed. Karcher does not even allow users basic access to change the SSID. Please point to the page in the Karcher user guide showing how to change the MAC address on their appliance.
