Python and Pascal are awesome. Dataflow is awesome. Not having to specify types is nice. Not having to deal with databases is awesome. Not having to deal with deployment is awesome. Keeping data in memory is fast.
Sounds like something I hope will be imitated and become popular in open source tools.
I had an interview at Goldman where multiple engineers explained to me that "there was no staging environment." No joke. They deploy everything straight to production, and when something breaks, they might lose millions of dollars.
So TL;DR - Slang is a weak Python-esque interpreted language that's old and horribly outdated, but holy cow would I like to know more about SecDB and the inner workings of what sounds like an incredible piece of software.
