λ> :t 1 1 :: Num t => t λ> :t pi pi :: Floating a => a In the examples above, the type-checker infers a type-class rather than a concrete type for the two constants. In Haskell, the Num class is the most general numerical one (since it encompasses integers and reals), but pi must...

Dual-purpose modules (refinements or global patches)

It's a good practice to scope patches using Refinements, but sometimes it's nice to load it globally (for example in development, or testing). Say for example you want to start a console, require your library, and then have the patched methods available in the global scope. You couldn't do this wit...

Plot live data from pipe with matplotlib

This can be usefull when you want to visualize incoming data in real-time. This data could, for example, come from a microcontroller that is continuously sampling an analog signal. In this example we will get our data from a named pipe (also known as a fifo). For this example, the data in the pipe ...
