Something happens to me occasionally, and I don't know where to put it in the ridiculous - infuriating - preposterous feelingspace. It happened again today.
Backstory: I'm an email geek, who has been running mail servers for three decades, and who has written a lot of mail-handling software. I've worked as a consultant on email systems for companies large and small.
When you run your own mailservers, have deep experience with MTAs, and are a bit of a privacy nut, you might have a tendency to want to know exactly who does what with your email address when you give it to them. For most people, this desire is just a dream; it's not possible with their email system.
Thanks to a technique semi-related to #VERP - variable envelope return-path, a mailing list feature with the qmail MTA - it's possible for email geeks. Basically the idea is that you give a different email address to everyone you deal with, and keep track of who you gave it too. Then, when you receive email, you can tell from the address the email was delivered *to* - one of your many addresses - where they got your address from.
Example:
Say I own the `example.net` domain. I arrange for all email to that domain to come to me.
I decide to order something online from #CrappyTire (ask a Canadian). When the Crappy Tire website asks for my email address, I type in "crappytire@example.net".

Esoteric question time.
1. Coffee shop chains used to have plastic "rewards" cards for #tracking purchases/points.
2. They seem like they don't offer them new anymore and want you to install their mobile app instead.
3. But they still accept the plastic cards if you have one.
Q: Why can't I buy a secondhand physical card from anybody? There's seemingly no resale market even among #privacy geeks. I've looked. Seems like a golden opportunity to me....
T-Mobile Shows Users the Names, Pictures, and Exact Locations of Random #Children
On Tuesday, some #parents lost the ability to #track the locations of their children using a T-Mobile #tracking device and app and instead were shown the exact locations of random other children around the country, 404 Media has learned.

Well there are a lot of these apps going around the internet, and very seldom does anything like this happen. I just don't want people thinking that tracking apps aren't safe. At least those that the backend doesn't fall off…

#DEDA - #tracking Dots Extraction, Decoding and #Anonymisation #toolkit
Document Colour Tracking Dots, or yellow dots, are small systematic dots which encode information about the printer and/or the printout itself. This process is integrated in almost every commercial colour laser printer. This means that almost every printout contains coded information about the source device, such as the serial number.
#France fines #Apple €150M for “excessive” pop-ups that let users reject #tracking

Windows 10 may very well be the last Windows OS that I ever run on any computer I own. I have never used Windows 11 and have been holding off upgrading as long as possible due to concerns like this.
I even have a Microsoft account, but it's the principle of the thing. Who actually owns the technology I use?
I have been tinkering with Linux off and on for nearly 20 years, with some long stints using various distros as my daily driver.
If Microsoft is going to be this way, so be it. I can get along just fine without them.
