Griff posted "in my experience, Chinese electronics have the same shelf life as cheesecake ..." and you said "It depends on the vendor honestly" and then I was thinking about cheesecake and relative shelf life.
Because I'm hungry and would kill for a decent cheesecake about now. But it would really depend on the vendor...
cheers

Against my (better) judgement I cannot help to chime in.
There was a time when war ravaged country recovered, with US help, and started competing with cheap and shoddy products. "They " soon realized that shoddy products where not selling and made a real cool stuff - likes cameras...and cars...boom boxes...
Most businessmen are "smarter then an average bear " to realize that quality sells in the long run,
they pay very little attention to narrow-minded opinions about "cheesecakes"- they will figure it out sooner or later.
On more serious note
I often wonder if the "problem" with electronic is "intellectual property" or US inability to actually manage the production - technologically and financially...
I guess I just keep wondering and buy what I need from whomever is selling it...
Yes - solid state electronic has a shelf life....
psst wanna buy a bridge ? cheap...

I think there's been a misunderstanding.
As I said to Griff originally, it all depends on the vendor.
AliExpress however, does no quality checking. They are just a clearinghouse for retailing stuff from China.
The vendors, well it depends. There are a lot of vendors who make knockoff gear. A lot of them sell on AliExpress.
But, there are good vendors out of China as I said, like Espressif, Makerfabs, and if I'm being generous, Lilygo.
So it just depends, pretty much like anywhere else, but for volume - China produces a LOT of stuff.

so, a number of my clients allow me to submit IT support requests via email. Since I'm not an employee, I have no access to the employee portal. I'm left to emailing support-asses@yourguess.com. I made that last part up.
me: "Hi, your remote server is not accessible, and I am on a tight deadline. Help."
email: "Opened on your behalf..."
email: "Your incident has been re-assigned..."
Via email, I have no ability to tweak the priority level. Or get any contact. I need to start an IT support company

When looking for IT support software that was on premises and not online, I was amazed how difficult it was to find something that catered for both our support and IT department needs. It seems support and development are different worlds and they have no clue what's happening on the development side or how information should be coupled with e.g. Git or Continous Integration systems.

Context: Merica!!!! where half the people don't pay taxes but can still vote... John, I need you now...
I actually retire in wait... checking... 8 days. I guess I would call my retirement a realignment of nonsense. My entire neighborhood is getting old. We love are homes and our land and are laid waste by GeekSquad and lawn care companies. I plan to pick up some cash...
The good news is that my MIL is legally blind (keeps her off the computer and makes for hilarious interactions with Nigerian or Indian scammers) and my FIL despises and is so luddite on computers it's a crime.
Meanwhile, the remote server seems to work, the corporate IT group are clueless - customer farmed it all out to some Indian group that are totally useless. Read more below. But you corporations that farm your work out... here's your sign: Google[^]
What I have purposed in my heart is elephant it. I worked till 9pm the last job I loved on the last day. Not this time.
Meanwhile, I have no response from IT....

I'm actually fighting a problem with a piece of commercial software that will go unnamed, but the first letter is Q. Support telling me to reboot after everything they do tells me two things: a) they really don't know what they are doing and b) their code has serious issues (that they ALWAYS blame on others.
The only reason I can think of to require a re-boot is if you are updating a Dll that is in use by the process. Even that is questionable, as the application should release it.

I had some fun with a bit of Microsoft nonsense the other day. I have a rather large hosts file - it's over 600KB. I read something about various devices phoning home to them with every URL visited so I put that address into my hosts file and mapped it to 127.0.0.1. I think it was urs.microsoft.com. Adding that single line to the file triggered the AV program at work and it was deemed to be malicious. At home it triggered a medium level warning when I did a virus scan. I removed that line and it accepted the file with no warnings or notification of any kind.
Apparently Microsoft deems it to be an act of malice to block one of their sites and I think that is nonsense.

Maybe you could try setting up a PiHole Pi-hole – Network-wide Ad Blocking, and add the offending address to the blacklist? Or just add the redirect to the hosts file on the system hosting PiHole (PiHole reads the local hosts file and adds entries to it's DNS database)?
There's instructions on how to install PiHole inside a docker instance, if you want to go that route.
Plus, if you can modify your DHCP server to point to the PiHole for DNS, than every system on your local net gets the ad-blocking goodness. Only downside (?) I've encountered is that PiHole does block google ad services, too, so you can't click on any "sponsored" google link, or the "Shopping" links when doing a google search. Which is occasionally annoying. You can find instructions on how to allow ad services through the PiHole, but I think doing so will allow a number of, possibly unwanted, other ad services through as well

Thirtysome years ago I designed and built cryptographic modules for EFT processing. Early days...
In those days there were two main algorithms for PIN verification.
The IBM Derived PIN system used data from the mag stripe (some of the account number and other fields) to crunch up with DES and other things to generate the expected PIN, which was verified by direct comparison (at a processing system, since the terminal did not have the relevant DES keys etc).
The (more popular) VISA method took the PIN and some stripe data, crunched them up and came out with a 4 digit value which was compared with the PVV (PIN verification value) from the stripe (or issuer's database).
This can be viewed as an elaborate hash function (4 digit PIN -> 4 digit PVV)
I investigated its properties as a hash, and (re-)discovered some interesting statistics.
Obviously a 1:1 mapping could be fairly easily brute-forced, so information is "destroyed" to make it a one-way operation.
As a consequence, looking at the PVV space:
1/e (almost 37%) of PVVs are unreachable - no corresponding PINs
1/e have one PIN mapped to them
1/2e (over 18%) of PVVs have TWO PINs that map to them
1/6e (6%+) of PVVS have THREE PINs that map
1/24e (1.5%+) have FOUR ... and so on
So, (back in PIN space) there is a very real chance that your card has more than one PIN that would work. (Good luck finding the other(s)!)
That fact blew the mind of more than a few bean-counters and auditors....
With regard to OG's thread below, we had requests from card issuing institutions to NOT generate "simple" PINs.
In the end I think we discarded PINs with 4 consecutive digits or more than two repeats.
(A little repetition is good - my favoured PINs have two characteristics:
They can be keyed by laying my hand over the PIN pad and merely flexing fingers.
They include a repeat so even keen watchers wind up missing something.)
Some time later, customer selected PINs (and PIN change terminals) hit the streets...
Ah, nostalgia (ain't what it used to be)!
