So I decide that getting out of the house is worth at least three dollars to me, and I got exchange my 3 USD for one latte. You can see how endlessly complex this is: If I had chronic pain, for example, I may not want to walk down the steps, so that changes my decision.
So I decide that getting out of the house is worth at least three dollars to me, and I got to exchange my 3 USD for one latte. Maybe I needed to do laundry at home, so staying at home and drinking regular coffee makes more sense. The coffee shop I went to has good sandwiches, so I chose it over other places that may also have decent lattes.
The woman working behind the counter is trading her time and labor for a wage paid by the company who owns the shop, and the company is trading some coffee beans, a bagel, and some other things with me, through the woman, in exchange for my money.
There is a subjective reason, though: They believe that for a number of reasons, including that our Army will go off and fucking kill anybody who threatens to break the spell that makes everyone agree that USD are worth your time to accept. Everyone agrees that dollars are worth something, and we trade them all the time. Euro is very not liquid, unless I deposit it with my bank, which will exchange those Euro for me for USD, which I can then trade for my coffee.
Really, liquidity is the aspect that matters to most people when it comes to basic financial transactions. This brings me to MtGox and CoinBase. We'd be able to understand this much more easily of we used Extract Method a few times to break it up, but then we risk polluting our Quote class with more stuff that's only relevant to pretty turnaround calculation.
Also, please ignore that this is also presentation on the model; we just care that it's a complex bit of code for this example. If you don't have a copy, get one. Here's the plan of attack:. I've changed this slightly for Ruby, since we can't Lean On The Compiler, and a few of Feathers' steps are about doing this.
Anyway, let's try this on that code. I like to give it a generic name at first, and then give it a better one in step 5, after we see what it really does. We should be able to run our tests and see them pass. Even if 'run our tests' consists of manually checking it out So what's the advantage here? Well, we now can start the refactoring process, but we're in our own little clean room.
Here's our class, a few refactorings later:. This code I wrote three years ago isn't perfect, but it's almost understandable now. And each of the bits makes sense. This is after two or three waves of refactoring, which maybe I'll cover in a separate post, becuase this was more illustrative than I thought This is what I mean when I say that I shoot for roughly five-line methods in Ruby; if your code is well-factored, you can often get there. This idea of extracting domain objects that are pure Ruby is even in Rails itself.

Funny thing is that bitcoin cash is seeing a surge in value after quite sometime. Andreas , Nov 11, Oct 8, Messages: Bitcoin was overvalued because of the upcoming fork since the price break down after the cancellation of the fork. Bitcoin cash is faster and has less transaction fees than bitcoin? I dont understand the rise of the BtcCash unstead of Alts. This is not the end.
This is just a normal correction after a long trend up. And the expected correction is up to Oct 27, Messages: BCH to the moooooon!
