local jargon, local domain knowledge (letter to friend

I agree that finance IT skills tend to "converge" across big banks, so we poor developers need not learn so many damn shit new stuff like GIT.

On the domain knowledge side, the "local system knowledge" has no convergence as such, so each time I take up a new system, I must spend the time on the stored procs, table relationships, batch jobs, feed files, etc. There are also a lot of non-technical local knowledge. I hear you when your manager complained "what do you know about the system?"

Local system knowledge can be a long learning curve. Those who write the code in the first place has a huge advantage --

"It takes me 3 months to write this damn shit, then we add new features and fix bugs, but it's still familiar to me. A new guy would take a year to get familiar code-wise, provided he has chance to explore all the key components. If he's only exposed to half the system, then he would never know  the other half."

(Therefore, I like to rewrite stuff.)

In http://bigblog.tanbin.com/2011/04/3-types-of-domain-knowledge-in-finance.html I mentioned 3 types of domain knowledge - Jargon, Math, and Architecture.The Math part is stable. Local system knowledge includes a lot of local jargon. Sometimes generic jargon can help us pick up the local jargon.
