One requirement of a project for the logistics industry was printing barcode labels in a GS1-128 format. I have written a library which lets you encode the desired sequence in a GS1-128 format. The barcode is automatically saved to the graphic or to […]

In the previous article I presented general information and technical details concerning the accordion and sound generation process. In this post I present a results of spectral analysis of the accordion music signal, including a different configurations of the registers.

The accordion is a musical instrument from the free-reed aerophone family. In this post I will present a general information about construction of this instrument and the process of the generating sound.

Visualization of a simple algorithms of two-dimensional Turing machine can create impressive images. The “movement” of the head of Turing machine can be irregular in the early stage, but it start making characteristic patterns after millions of iterations. In this post I will show how to define a table of rules the Turing machine for a simple cellular automaton that is Langton’s ant and sample visualizations of the work of other machines.
