Are there any documents that share the wisdom of past developers. Is there any place where developers share pseudo-code, problem solutions, code files, etc. For example logging on. Currently (I don't really remember, but I think) I try to log on, wait 10 seconds and check to see if I am logged on. If not I try again, etc. What is the best practice.
There are lots of these common problems that everyone must solve. Like downloading historical data for many symbols efficiently. Correcting stored historical data for splits is another.
I code in Java but pseudo-code would be helpful to all.
Thanks,
