Problem

Od jakiegoś czasu na moim komputerze tuż po uruchomieniu się systemu (Windows 10) pojawiał się popup z komunikatem o treści Wystąpił problem podczas uruchamiania pliku SBAVMonL.dll Nie można odnaleźć określonego modułu.. Było to dość irytujące, zwłaszcza, że dosyć ciężko było znaleźć rozwiązanie tego problemu :/

Making Chiptune Music using Sonic Pi v2.0

Warning: this might not work on a RaspberryPi yet

I was curious about making retro gaming sounds using Sonic Pi. A couple of months and a lot of Googling later, here's the original Mario Bros theme as it was heard on the NES console.

I'm (just about) old enough to remember rushing home from school to play this game at Philip Boucher's house, sitting cross-legged in front of the TV till my feet got pins and needles. Working out how to recreate it for Sonic Pi was a lot of fun!

Vagrant Setup

This tutorial guides you through creating your first Vagrant project.

We start with a generic Ubuntu VM, and use the Chef provisioning tool to:

install packages for vim, git
create user accounts, as specified in included JSON config files
install specified user dotfiles (.bashrc, .vimrc, etc) from a git repository

Afterwards, we'll see how easy it is to package our newly provisioned VM

	# drumloop based on

	# If You use v3.x + then it'll sound other than intended.
