Ruby in 30 minutes

I have a problem with Ruby. It is a great language , extremely good for fast prototyping. However this is not the language I use it daily. However, there are times when I have to use ruby where the effort of doing something in a different language is not worth it. My problem stems from the fact that I forget the syntax as I don’t use it regularly. In the last 1 year , I would have probably worked on 4 RoR mini-projects and in every instance I had to pain stakingly go through and review the syntax .

Why

The trading strategy that I have been trying to back test does very badly in one fortnight. Huge drawdown! Have been trying to figure out an answer to the question ? why? Hoping to find an answer soon.

Beautiful day

It is a beautiful day outside, a little drizzle which I can see from my window, a silence which allows a mind to clearly think and reflect. I don’t have to go to work today.I don’t have to think of bug fixing, deadlines, work allocation, assignments, grading, etc for ONE day. What can I think of doing in the coming 24 hours ? Sometimes the feeling of having 24 hours to yourself is quite liberating.

Bayes Vs Fischer

Another difference which one can keep in mind to understand the philosophical difference between Bayes and Fischer’s way. In the context of parameter estimation, Bayes World : Parameter is random and credible intervals are fixed and one talks about the probability that estimator is present in that interval.Probability being referred to the posterior probability of the parameter Fischer’s world : Parameter is constant and confidence intervals are not fixed. For example 90% confidence interval means, if a large number of independent 90% confidence intervals are constructed, then approximately 90% of them will have the true parameter.

Making Money OR a Bug

If a trading strategy makes money continously for the last 6 years with 40% annualized return, what should I make out of it ? Is it really that GEM of a strategy OR is it a BUG in my code and I am living in a fantasy world. Have been struggling for the past 4 days. Hope to answer the question soon. I don’t wish anything as of now..Just want to see some correct numbers, even if the numbers turn out to fantastic or pathetic :)
