RE: Deploying, Voting, RCs
The whole roll-out was surprising, although this was my first HF so I had no knowledge of what was done previously.. I was expecting some sort of beta fork that ran for a couple weeks in parallel and replayed

RE: Are Humans evil?
The document you link rules out a first strike. They closest they come is a "pre-emption" option that was under the assumption they detected an imminent attack. You're describing a nash equillibrium

RE: Are Humans evil?
I agree with your conclusions that centralized power enables worse crime and that technology can help, but your premise feels like a fundamental attribution error. It's not clear what their intentions

RE: Would you love to see how I trained my small, tiny, powerful neural network?
One technical tip: .csv (comma separated values) and .txt (text) formats are the same data encoding. The difference is the file extensions can tell the operating system what types of programs should open

RE: Telegram Traffic was Hijacked
It would be really helpful if you could link sources of info. Based on the quotes from Woodward it looks like it could have came from this story (or also a dozen others..), which has a really helpful twitter

RE: Ancient Cryptography: The Scytale
There's a scientific journal you might find interesting: Cryptologia It has articles going back to the late 70s, and it is dedicated to historical cryptographic systems and how they were used. I find it

RE: Tor
This is a reasonable summary. For those interested, the technical details are published in the paper, and that work has its roots in untraceable electronic mail paper from the 80s.

RE: Ethereum private keys and public addresses comparison..
I'm not sure because it depends on the software implementation. Assuming the software does not check, it will appear you have a balance when you start. When/if you transfer eth the original owner will

RE: Ethereum private keys and public addresses comparison..
Just looked at the paper, page 19 appendix F: it goes from private key (256 bits) to public key (512 bits) to the address (160 bits). So yeah, there could be 2^256 / 2^160 = 2^96 (or 7.92E+28) keys per

RE: The Quest For Knowledge Begins With C
Glad to help—baby steps are asbolutely the way. A lot of people say the most important thing in programming is learning how to learn, but I think it's going from a high-level goal, and breaking that goal

RE: The Quest For Knowledge Begins With C
As a former computer science professor for a number of years, I strongly recommend starting with Python over C, but the book you have is a classic and I have the same one on my shelf. To back that up,

RE: Ethereum private keys and public addresses comparison..
The public address is different from the public key. This is explained in the yellow paper in the appendices somewhere, but it uses the ECDSA and a hash function (Keccak, IIRC). The address is created
