Everything is logic and math, therefore a computer is the most fundamental machine because its purpose regards performing all logic/math operations from the simplest up to the most complex it can physically represent. Despite this somewhat philosophical sentence, I`m usually working with open source, Linux and C. As an additional experience, I`m also working with C#, .NET Core framework, and ECMAScript (a.k.a. javascript) for developing web applications for a company (I would like to use C, though :-) ). ©
