Erlang supports a way to implement functions in C and use them transparently from Erlang. These functions are called NIFs (native implemented functions). There are two scenarios where NIFs can turn out to be the perfect solution: when you need raw computing speed and when you need to interface to existing C bindings from Erlang. In this article, we're going to take a look at both use cases. Note t
Elixir is frequently used in network-aware applications because of the core design of Erlang and the Erlang VM. In this context, there's often the need to connect to external services through the network: for example, a classic web application could connect to a relational database and a key-value store, while an application that runs on embedded systems could connect to other nodes on the network
Lexical analysis (tokenizing) and parsing are very important concepts in computer science and programming. There is a lot of theory behind these concepts, but I won't be talking about any of that here because, well, it's a lot. Also, I feel like approaching these topics in a "scientific" way makes them look a bit scary; however, using them in practice turns out to be pretty straightforward. If you
