Every now and then there is a need to pass arguments to the command-line application. While there are a lot of libraries/frameworks to do that in Java, I still had this feeling “why such an easy thing must be so cumbersome and require so much boilerplate?”.

Building up on my previous posts about MIO-based server and parser combinators, this post is about making a very simple HTTP server capable of running on multiple threads and implementing WebSocket protocol.

One evening I was thinking why don’t I implement throttling dispatcher in Go. I even had to find “The Go Programming Language” book on the shelf, it was waiting for this for more than a year.

Why don’t I implement a nice monadic parser combinator library in Rust? That’s what my thought was when after implementing low-level mock-HTTP server in MIO and actually needed to parse the bytes received by server.

Once I was wondering, how different the ‘hello world’ in assembler on Linux would be from one on MacOS.
