Ask HN: Could true randomness come from sparkles from light reflecting the sea?
7 by danielovichdk | 4 comments on Hacker News.
I am not well rounded in cryptography, but I had this thought about having a camera take pictures of the sea, and somehow turn the sparkles from the light hitting the sea into a useful indicator for some kind of randomness. So the camera takes a shot. Software looks at the image, collects the "sparkles", somehow counts and sums them up, perhaps multiples them with a second random counter and then we have a true random number. Does it make sense ?

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.

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
