Very specifically line 24 in my SVN chechout contains the following number, but there is no explanation as to why this number is there; I can guess why it is there, but it shouldn't be my task to figure out why something is there. A comment above this constant should say why exactly it is that value and not some other value, why it is important for the system, etc.
uint256 hashGenesisBlock("0x000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f");
Lol
As the name of the variable indicates it, it's the genesis block. I guess it's the public key of the first ever bitcoins.
This is certainly not the best critic of Satoshi's code you can make.
The genesis block part was clear, but note that you have to guess the exact same information. Your guess is also still completely vague. In a computer program there is only one answer and in a good program one should not need guessing.
I don't see why I should even point out any other issue if this is clearly a valid objection.
