Episode 0. Hack vs Mac. Xcode build time

Episode 0. Hack vs Mac.

Proof-of-Proof-of-Work on the fingers. On the way to a sensible blockade

Proof-of-Proof-of-Work on the fingers. On the way to a sensible blockadeThe blocking protocols should provide a consensus among the nodes of the decentralized system. Perhaps the most famous consensus algorithm can be considered "braked, but reliable, because the braked" algorithm of Proof-of-Work: each node, having a set of new transactions, sorts through a certain number of nonce, which is the field of the block. A block is considered valid if all the transactions inside it are valid and the hash function of the block header has some common feature (for example, the number of zeros at the beginning, as in Bitcoin):

FusionPBX, or again-great, FreeSWITCH

In the same river


 
Relatively recently, I wrote myself cheat sheet on setting up FreeSWITCH. The configuration process described there led to a workable configuration in the test environment.

However, when the move took place and the connection started in the working mode, the first activation showed the inoperability of the configuration: internal calls stopped walking.
