Companies using DSLs with Functional Programming Languages

One of the questions that has been lingering in the back of my mind for a long time is “When should a company use a DSL?”. My stock answer has always been “When it makes sense.”
Perhaps a better way is to answer that question is to look at how companies are actually using them today, rather then to simply guess!
Have a look at the “case studies” section in this presentation on ContractML to see how companies are using DSLs today.

Why mathematics is not fun (when it should be!)

One man’s lament.

Addendum: 8/6/8
On vacation, I re-read this, and wanted to share some interesting bits:

  • p5. Mathematics is the art of explanation.
  • p6. Math is not about following directions, it is about making new ones.
  • p7. It isn’t doing anyone any good having vague memories of formulas and clear memories of hating them.
  • p11. Teaching is not about information. It’s about having an honest intellectual relationship with your students. Teaching means openness and honesty, an ability to share excitement, and a love of learning.
  • p21. Mathematics is about removing obstacles to our intuition, and keeping things simple.
