The literal translation from Greek is “unpublished” which refers to a short incident irrelevant enough to not be part of the main story. In modern Greek anecdoto means joke.

The training phase is when you are trying to minimise your loss function by trying different weights each iteration.

Once that is finished, you have a trained model which you can use by providing input and getting an output (with the weights frozen).

The training phase is very expensive computationally because you have to calculate the gradient of your loss function on potentially huge tensors.

The execution phase is not that expensive and commercial laptops will be likely able to run the model without any problems.

sethgeckoon De Beers admits defeat over man-made diamonds

This video that was uploaded yesterday explains very well how humans inherently value scarcity, even from a very young age. It could be shells/weird looking stones/trading cards/gold/cryptocurrency. If it is rare humans will value it.

If you could create diamonds at will in a lab the price of it's price is bound to go down significantly, it's not just a matter of supply and demand.

sethgeckoon Pwned Passwords in Practice: Real World Examples of Blocking the Worst Passwords

I think what he means is that searching by full hash will be removed in favour of using the /range endpoint (the one I am using)

sethgeckoon Low Level Bit Hacks You Absolutely Must Know

As a Python developer who recently wrote a pure Python ECDSA/bitcoin library, these are very helpful. However performance is not always better. For example I had this function:

    def point_mul(p, d):
        n = p
        q = None
    
        for i in range(256):
            if d & (1 << i):
                if q is None:
                    q = n
                else:
                    q = point_add(q, n)
    
            n = point_add(n, n)
        return q

but when i changed the loop to this :

    for i in reversed(format(d, 'b')):
        if i == '1':

I found out it performed much better.

This way you are adding more complexity which in turn adds more loopholes. A good tax framework should be as simple as possible to avoid this type of shenanigans.

sethgeckoon Proof-Of-Work is a Decentralized Clock

Fascinating, I found this article by Vitalik that explains what happened. In v0.8 they swapped from BerkleyDB to LevelDB but due to a bug the two chains started diverting.

sethgeckoon Keybase is now supported by the Stellar Development Foundation

Only the third party issued tokens have counterparty risk i.e you trust the issuer to redeem them somehow. Is that different than an ethereum ERC20 token? The native asset itself (XLM) has no counterparty risk.

> The only networks capable of providing fast, cheap, worldwide payments are decentralized protocols without trusted third party intermediaries, like Bitcoin (Bitcoin Cash) and Ethereum.

IMO it is a trade off between degree of trust and scalability. Bitcoin requires no trust but has a costly PoW consensus algorithm which does not allow instant transactions and has a very low tps limit. You can't have both (unless someone comes up with a better consensus mechanism)

sethgeckoon Spotify Form F-1

I noticed recently that the new discover weekly songs tend to sync perfectly with my walking speed. I wonder if I subconsciously leaked some bias into my training sample. BPM has to be one of the factors they are matching against.
