    That’s not correct. Under the GDPR, the data that Facebook collects on you makes them the Data Controller. Any partners they share data with would be considered Data Processors. When you invoke your right to be forgotten under the GDPR, then both Data Controllers and Data Processors must delete your data. So if Facebook partners isn’t deleting your data after you filed a request to Facebook, then they are violating the GDPR.

    That said Facebook is certainly violating the GDPR left and right. For example with their “Pay or Consent” model…

    These are great points, but there is something more that phones have going for them.

    All modern phones are full-disk encrypted by default, and can be remote wiped. I think this is only the case for Mac laptops, but not for Linux and Windows.

    So if your phone is stolen, it’s not really a risk of the thief having your password manager and your 2FA at the same time, but rather can they get in to your phone and then password manager and 2FA before you can trigger the remote wipe.

    Unless the attacker is sophisticated enough to mirror the whole disk and attack it offline.

    The idea is that you could have your data stored encrypted, such that the entity that is storing your data can’t read any of your data, but can still make calculations or updates to your data without ever learning anything about your data.

    The use cases seems rather narrow to me, but there are probably many that I just can’t think of at the moment.

    One idea could be something like a VPN service that wants to store as little data about the customer as possible. They could keep the account balance in an encrypted format. When you then add money to the balance, they can increment your balance by however much you paid, without knowing what your old balance was or what the new balance is. And they could then have another homomorphic function that can check whether your balance is positive. If your balance is positive you are allowed onto the service, if it’s not positive you don’t get access. And the company wouldn’t be able to know whether you had $5 in your account or $5000, just that your balance is currently positive.

    So yeah fundamentally it’s just being able to store and update some data, while the data is fully encrypted, never decrypting the data, to ensure some form of privacy or confidentiality

    Unittest in Python, enjoy! If you pass it with a function like the one in OPs picture, you have earned it.

    import unittest
import random

class TestOddEven(unittest.TestCase):
    def test_is_odd(self):
        for _ in range(100):
            num = random.randint(-2**63, 2**63 - 1)

            odd_num = num | 1
            even_num = num >> 1 << 1

            self.assertTrue(is_odd(odd_num))
            self.assertFalse(is_odd(even_num))

    def test_is_even(self):
        for _ in range(100):
            num = random.randint(-2**63, 2**63 - 1)

            odd_num = num | 1
            even_num = num >> 1 << 1

            self.assertTrue(is_even(even_num))
            self.assertFalse(is_even(odd_num))

if __name__ == '__main__':
    unittest.main()
