Most programming languages were designed before the age of web. This matters because the web changes many assumptions that typed functional language designers tak for granted. For example, programs do not run in a closed world, but must instead interact with (changing and likely unreliable) services and data sources, communication is often asynchronous or event-driven, and programs need to interoperate with untyped environments like JavaScript libraries. How can statically-typed programming languages adapt[...]

Try WebSharper reached an important milestone today: we just released the first bits of on-the-fly typechecking and code completion, and you can now develop F# web snippets, without any installation, online more easily than ever.

It often surprises me that people who spend their whole day focusing on details, software developers, so often ask question in broad and generic terms.  Here’s some that I’ve heard over the years: Why should I learn Object Oriented Programming?  (I have been writing software for a while.  Long enough to remember the days before […]

Tweet NOTE : read the rest of the series, or check out the source code.   Prologue I was at Joy of Coding earlier this year and one of the highlight for me was Crista Lopes’ keynote  Exercises in Programming Style. Crista demonstrated how a simple problem of calculating term frequency can be written in

A while back Scott Wlaschin posted a great blog post on what he called “Railway Oriented Programming.”  It’s a great treatment of a common problem in adopting functional programming; how to handle a chain of functions when one of the functions in the chain may return an error.  Of course stopping the chain when the […]
