A man is engrossed in his smartphone; a giant tentacled 14-eyed cartoon-pathogen blob labeled SOCIAL MEDIA DISTORTIONS has swallowed his head. His wife/partner, reading a book, a cat on the armrest beside her, remarks, “Why do you think they call it ‘viral’?”

A wife asks her engineer husband, “Could you please go shopping for me and buy one carton of milk?  And if they have eggs, get six.”

A short time later, the husband comes back with 6 cartons of milk and no eggs.  The wife asks him, “Why did you buy six cartons of milk?”

He replied, “They had eggs.”

"Google tracks you even if Location History's off. Here's how to stop it" (Wired)

"... the search giant still tracks you every time you open Google Maps, get certain automatic weather updates, or search for things in your browser. There's a way to stop it—but it takes some digging.

The problem affects anyone with an Android phone and iPhone users running Google Maps on their devices..."

Turning off Location History is not enough. You also need to turn off Web & App Activity.

"Sign in to your Google account on a browser on iOS or your desktop, or through the Android settings menu. In the browser, access your account settings by finding Google Account in the dropdown in the upper right-hand corner, then head to Personal Info & Privacy, choose Go to My Activity, then in the left-hand nav click Activity Controls. Once there you'll see the setting called Web & App Activity, which you can toggle off.

On your Android phone, go from Google settings to Google Account, then tap on Data & personalization. You'll find Web & App Activity there."

Happy Pi Day! (3/14)

There are even delicious-looking counterexamples to "Pi r square? Pie are not square. Pie are round. Cornbread is square":

Broadband over 'wet string' tested for fun

Broadband can be sent over 2 meters of string wet with salt water.

Engineers at a small British internet service provider have successfully made a broadband connection work over 2m (6ft 7in) of wet string.

"Here the string is acting as a waveguide to transmit an electromagnetic wave. And because the broadband signal in this case is very high frequency it doesn't matter so much what the material is."

The connection reached speeds of 3.5 Mbps (megabits per second),...

Watchdog Group Files Complaint Over Google Tracking In-Person Purchases (NPR, All Tech Considered)

[I already use several defenses against such things: a non-tracking search engine (DuckDuckGo), an ad blocker, avoiding apps with ads, and keeping location turned off on my phone except when needed for navigation. The ExtremeTech article on this also suggests staying logged out of your Google account except when needed.]

A privacy watchdog group has filed a complaint with the FTC over Google's system for tracking purchases Internet users make in person, at physical store locations.

Google announced the new service — a way for advertisers to measure the effectiveness of an online ad campaign — in May. It combines Google's search and app records with credit card purchase data acquired from third-party sources.
For several years, the company has been using location data on phones to track store visits — for example, to see how many people clicked on a PetSmart ad and then visited their local PetSmart.

But the new system goes further, and looks at actual purchases, by relying on in-store credit card transactions. [...] That data gets cross-referenced with information Google already has, to connect user accounts to in-person purchases.


Rotenberg says that Google has never identified who its third-party partners are, "what data is acquired or what steps they are taking to de-identify that data." Without those details, he says, there's good reason to be skeptical of the company's claims of anonymity.

He points to examples like Snapchat, the app that said that photos posted on its platform would disappear forever. EPIC challenged that claim in an FTC complaint. The FTC agreed that Snapchat was being misleading, and the company eventually settled the charges.

Rotenberg says that if Google's anonymizing practices are as robust as they say, that likely alleviate EPIC's privacy concerns. But without an independent investigation, he says, it's impossible to evaluate Google's claims that the process is fully anonymous.

EPIC also complains that the opt-out process is "opaque and misleading," [...]
