Serve different services on the same port using github.com/soheilhy/cmux! When your app exposes a REST endpoint, you are always lured to serve every other service via HTTP. If you build a distributed system, the first option for internal RPCs would be HTTP. If you build a client for your service…

While working on Beehive’s API, I observed a pattern similar to @davecheney’s functional options: We have lots of configuration options that their values can be (a) set by the user, (b) overridden through command-line flags, or (c) set using a default constant value. In an effort to generalize that, I developed a library called args (https://github.com/soheilhy/args). Here is an example: The end-result is very similar to Python’s kwargs: Instead of writing Server(listen_on=80), we write Server(ListenOn(80)). Although you cannot pass an arbitrary parameter name as in Python, args is safer and, in my very biased opinion, looks a little bit more elegant.

Simpler functional programming in C++11 — STL comes with an extensive set of tools for functional programming, ranging from std::remove_if() to std::transform() to std::accumulate(). For example, you can solve Euler Project’s Problem 1 in C++11, functional-style: #include <algorithm> #include <vector> #include <numeric> std::vector<int> v; // You can replace this with std::generate, but let's forget // about that in this example for…

Sleep tight, if you hack in programming languages that protect you from embarrassing optical illusions. In Python, indentation is the flow (and so is in Occam): if condition: fail fail Go, on the other hand, enforces blocks: if condition { fail fail } And so does Ruby, Pascal, Basic, and MATLAB. Haskell elegantly supports both: “If you leave off the braces and semicolons, then indentation becomes significant.”
