After upgrading an old Rails app from 3.2.x to 4.0.x I started getting a really weird error. Made all the more confusing by the fact that I couldn’t work out why it was trying to load Moped (given Mongoid 5.0.0 no longer uses Moped).
One of the things that I’ve been doing sporadically over the last couple of years is dabbling in Automated Trading. Now when I say dabbling, I mean small fry. Mostly playing with backtesting and the occasional test with small amounts of real money.
It’s been interesting, and I’ve learned a lot (many of the ‘things not to do’).
The following is a collection of useful tools and learning resources.
This will be my second year documenting things that I want to do this year and giving myself a mark on the results. I found it to be a valuable exercise last year, though my priorities did shift over the course of the year.
