What is Bitcoin? To start with and avoid confusion, we need to separate it into two components. On the one hand, you have bitcoin-the-token, a snippet of code that represents ownership of a digital concept – sort of like a virtual IOU. On the other hand, there is a bitcoin-the-protocol, a distributed network that maintains a ledger of balances of bitcoin-the-token. Both are referred to as “bitcoin.” The system enables payments to be sent between users without passing through a central authority, such as a bank or payment gateway. It is created and held electronically. Bitcoins are produced by...

At every Ruby meetup you are most likely to hear two things: Ruby is slow and it has GIL. All Ruby developers know about it and it was strange to face this topic at the conference again. However, after talking to other developers I was surprised to learn that only few of them know when it is better to write parallel algorithms in Ruby. The majority said that there was no point to use parallelism as all threads were executed one by one (thanks to GIL). I will try to show you the cases when concurrency and parallelism make sense. Data Recovery from Memory Card Once I needed...
