The Difference Between “Good” and “Great” – Massive
Today had been a lot of system-level integration work and it's getting a little frustrating. For example, today I learned that I needed to provide the model with the latest trade prices for stocks as well as the quotes and associated data. Why I didn't know about this weeks ago, I have no idea, but I guess that's the joy of working with just in time memories. Specifically, it's because I didn't play a more involved role in the beginning of the project. I trusted my teammates, who have worked with this library before, to know all the inputs and let me know well in advance of needing them.
Nope.
So I'm finding out today that I need to add in another 20-plus feeds to the system and that means dealing with a different level of abstraction on the stock feeds - which is nice, and that in turn means a good bit of re-factored code to make the abstraction work well. It's nice to see it done, but it's not nice that it was a surprise.
Hopefully tomorrow will be fewer surprises.
