How do I find a hash with leading zeros?

I came across a similar question that was asked, but the answer did not seem quite complete. Coding is completely alien to me and I've spent some time trying unsuccessfully to solve it. I try to increase the difficulty by getting 8 leading zeros and the corresponding nonce for the initial hash (no previous blocks) in Python. Any direction here is appreciated

import hashlib

m = hashlib.sha256()
m.update(b'Your Name')
m.digest()
m.hexdigest()

'9cd26bee4d76694cb03cfee8c2355a83339157f2e9234fd1352c12597da72474'

google – Strange / http URL pattern leading to many 404s

I received very strange 404 values ​​from the Google Search Console. It shows me some kind of URL confusion and I can not pinpoint exactly where this pattern comes from. It's a WordPress installation.

Do you know how these were produced?

Message Signature – How difficult is it to create an ECDSA (or Schnorr) signature with a certain number of leading zeros?

If both the public key and the private key are known anticipatory (public knowledge), and the goal is to select a message / nonce that generates a signature with, for example, a certain number of leading zeros, this is a computationally intensive task like the conventional "hard to find" but "relatively" easy to verify? "

Apparently, the answer should be "yes", because if the answer is "no" (I think?), This would mean that signatures for different messages are not pseudorandomly consistent.

Can a signature, perhaps more succinctly, also be used to provide specific proof of the work?

Finally, will you answer one of the above changes if the signature scheme used is Schnorr rather than ECSDA?

Analytical formula for leading eigenvector of $ uu ^ T + vv ^ T $?

To let $ u $ and $ v $ Be non-zero column vectors of size $ n $ and look at that $ n times n $ Positive Definitely matrix $ A: = uu ^ T + vv ^ T $, In this post https://math.stackexchange.com/a/112201/168758 are the eigenvalues ​​of $ A $ were calculated analytically.

question

I wonder if there is an analytic formula for the eigenvectors of $ A $,
