  • It’s called the ‘inner platform effect’. They are basically replicating parts of the underlying platform (the OS in this case) inside their own application, until the application turns into a platform itself, one crappier than the one below it. You see this happening with web browsers and ‘web apps’.







  • It’s so absurdly big. Our galaxy (the Milky Way) is estimated to have between 100 and 400 billion stars in it. For a long time we thought our galaxy was all there was, it wasn’t until 1925 when Edwin Hubble was able to prove that M31 was not a nebula or cluster of stars in our galaxy, but in fact an entirely different galaxy altogether that we realized there are more galaxies out there.

    Look at the Hubble Ultra Deep Field picture

    This was a taken by pointing the Hubble Space Telescope at a basically empty bit of space 2.4 by 2.4 arcminutes in size (for comparison, the moon has an apparent size of about 30 arcminutes, or half a degree). So an absolutely tiny part of the sky. It contains about 10.000 galaxies.

    The observable universe is estimated to have between 200 billion and 2 trillion galaxies in it, with on average about 100 billion stars per galaxy. It’s absolutely mind blowing.








  • Doesn’t this sort of bypass the whole point of encryption in the first place?

    No, homomorphic encryption allows a 3rd party to perform operations on encrypted data without decrypting it. The resulting answer is in encrypted form and can only be decrypted by whoever has the key.

    Extremely oversimplified example:

    Say you have a service that converts dollar amounts to euros using the latest exchange rate. You send the amount in dollars, it multiplies by the exchange rate and then returns the euro amount.

    Now, let’s assume the clients of this service do not want to disclose the amounts they are converting. What they could do is pick a large random number and multiply the amount by this number. The conversion service multiplies this by the exchange rate and returns the ridiculously large number back. Then you divide thet number by the random number you picked and you have converted dollars to euros without the service ever knowing the actual amount.

    Of course the reality is much more complicated than that but the idea is the same: you can perform operations on data in its encrypted form and now know what the data is nor the decrypted result of the operation.
