The leading forum for research & development related to the Scala programming language.
Marius Eriksen
Principal Engineer, Twitter
Scala is a large and very powerful language. This is simultaneously its
greatest strength and weakness. On the one hand, Scala is adaptable: it is
used in a wide number of applications, from web programming to data processing
to DSLs to systems programming; from strong typing to weak. However the
drawbacks are also considerable: the unsuspecting outsider sees a playground
of ideas; a bewildering buffet of syntax, abstraction, and typing. If
something is to be done, Scala offers five ways to do it.
So how do we make Scala work in a large-scale setting, where thousands of
engineers grapple daily with millions of lines of code? What works well today,
what doesn't? What matters in this setting, what does not? How can Scala
evolve to better support large-scale software engineering?
I will talk about how we make use of Scala at Twitter; about which features
have turned out to be indispensable, as well as those that have not; the tools
we employ, the ones we wish we had; how we teach newcomers, and how they fare;
and about the practicalities of maintaining a large and highly interdependent
Scala codebase.
Finally, I will present a number of open problems.
