The other day I was interviewing at one of the companies, and I was asked the following question, how can you count occurrences of a word in a 50gb file with 4gb of RAM. The trick is to not load the whole file into memory and keep processing each word as we keep on moving the pointer of the file. With this, we can easily process the whole file with a minimal amount of memory resources.
Nowadays, the successful application often consists of containers and some sort of container management system to ease scaling, reduce downtime, and more.

Streamlining Your Code: An Introduction to the Builder Pattern in Go
For the most part, Go developers are pretty good about using constants for global configuration, rather than global variables. A problem arises however when we want a global constant slice or map. The go compiler doesn't allow these more complex types to be set as constant. Many developers, upon making this realization, decide to then use a dangerous global variable. In this article we will explore a better option.
In this article, we will try to understand two crucial Go concepts - mux and Handler.

I love pet projects, they are great excuse to use libraries and other technologies that you can’t use at work. Lately I’ve been working on a bigger pet project that needs to parse Go files, I’ve used ANTLR before to make this kind of things but unfortunately, ANTLR’s Go target has poor performance. So I began to search for alternatives written in pure Go and came across with this one, which took a different approach on creating parsers with Go, but before we’re going to understand how this library is different from others, let’s cover some basic concepts about parsing.
