Ask HN: Any tools to do generic WiFi imaging?
10 by selfsimilar | 3 comments on Hacker News.
I have an older house (1950s) and I'd really like to see behind my walls without physically excavating so I can try to run some wires without encountering surprise obstructions. There are tools which use WifI to do detect humans[1] (https://ift.tt/KlFzdmZ) [2](https://ift.tt/T6WcalF) but I'm looking for a way to use Wifi for more general imaging. There's a paper from 2017 ("Holography of WiFi Radiation)[https://ift.tt/tTYAGDS] and many other scholarly papers about object detection via WiFi, but I haven't been able to find any off-the-shelf products/projects that would just build a 3D environmental density map without any object detection. The resolution doesn't have to be great - not looking for millimeter scale features e.g. structural weakness. Is there anything out there that comes close? Given recent archaeological uses of drone LIDAR and satellite tomography, I figure the software for interpreting this kind of data should be pretty robust by now, just maybe it hasn't filtered down to the consumer market.

New ask Hacker News story: Brother Printers Sending Ink Data to Amazon?

Brother Printers Sending Ink Data to Amazon? 29 by Ajay-p | 13 comments on Hacker News. A most unusual thing. Every once in a while I get an email from Amazon that it's time to re-order Brother ink. I always delete these because I rarely print, but also figure it's just Amazon reminding me to buy something. Today I decided to opt out/unsubscribe once and for all. Instead I see this at the bottom of the email: "Click here to view or manage settings, including the option to opt out if you are already using another replenishment service. This took me to https://ift.tt/nMGIXiy "The data shown is based on estimated consumption reported by smart devices and orders you place through Amazon." Here it had a link to "Consumption history" which upon clicking showed me the ink levels of my Brother printer for the past two weeks . Date and time. WTF?! It is not apparent that I can disable this function. Can anyone else duplicate? Update : This is part of Alexa it

New ask Hacker News story: Tell HN: Equifax free credit report dark patterns

Tell HN: Equifax free credit report dark patterns 4 by PopAlongKid | 0 comments on Hacker News. For years, I have been obtaining free annual credit reports (annualcreditreport.com) which must be provided by law. Recently, for the first time, when I tried to obtain my Equifax report, I was prompted for an email address and a mobile phone number, a new requirement that apparently cannot be bypassed. The other two bureaus, and Equifax previously, confirmed identity by asking knowledge based questions. They do not need my phone or email for anything. Next, trying to obtain the report by phone instead of web site per instructions, I got to the point where I entered my ZIP code on the phone keypad, the voice menu system correctly repeated the number back to me, but every time I press 1 to indicate it is correct, the system acts like it got an invalid response and only gives me the option to enter further information by voice, not by the phone keypad. Just as with my phone number and email
