Veterius: Transfer of water to the phone via Wi-Fi (4 years from the batteries)

Veterius: Transfer of water to the phone via Wi-Fi (4 years from the batteries)
 
 
Once I was tired of taking water readings. It was possible to settle a magnet near the counter and to calm down on it, but this way I found unsportsmanlike.
 
 
My path turned out to be difficult and ornate. But the result was a device that sends water readings via Wi-Fi to the phone. Simple and easy to use and configure at least a student, at least humanities pensioner. And the familiar with the word "Arduino" is also uncomplicated for manufacturing. The device is able to work on batteries for four years (longer than the relationship with your former one lasted). This is also the first open project ...

Firefox will check the compromised passwords using the k-anonymization method

Firefox will check the compromised passwords using the k-anonymization method  
 
On Habr repeatedly mentioned the useful service Have I Been Pwned (HIBP), where you can safely check your password for leakage. People often use one password on many sites, so one small leak from any of these sites compromises everyone else, and at the same time, the "digital identity" center is a person's mailbox, through which you can change passwords on almost all services.
 
 
Unfortunately, the HIBP service is little known to the general public. Therefore it is very pleasant that the developers of Mozilla ...

FIDO2 - Passwords must die

I think all of you have repeatedly heard about the fact that "passwords are dead", "passwords are dying out", "new technology will kill passwords" and the like.
 
 
We in FIDO Alliance just came to inform you that passwords will still die out in authentication.
 
 
FIDO U2F about which I wrote earlier .
 
 
FIDO2 - Passwords must die  
 
That is, the authentication script with U2F is as follows:
 
 

The registration is:


 
- The user registers using a user name (can be better changed to a password, and then user-user?) And password

Firefox Gecko, "which we lost"

Firefox Gecko, "which we lost" Evolution is on, and weaker, slower and ineffective organisms are dying out. Not so long ago we spent in the abyss of the history of the Opera-1? looking somewhere into the distance, silently listening behind the sobbing of sympathizers. Unlike the body of the last animal from the Red Book, it could still be used for 2-3 years, and the users did not look like necrophiles. A similar situation is repeated with Firefox on the Gecko engine with the latest most convenient version of ???. There is a lot of useful and habitual functionality, not only built-in, but also in add-ons (extensions). Even reduced performance ...
