Welcome. This site contains a collection of open articles, documents, software I have written mainly for educational purpose.

nuBASIC

nuBASIC is a programming language from the BASIC family distributed under MIT License.

Ever since starting writing BASIC programs on my Commodore 64 at age of 8 I've always wanted to write a BASIC interpreter.

Years later, during a programming course of C++11 which I taught in 2014, I decided to implement an interpreter as a non-trivial programming example, and my choice fell on such language exactly fifty years after John G. Kemeny and Thomas E. Kurtz designed the original BASIC language.

nunnLib

nunnLib is a Free Open Source Machine Learning Library distributed under GPLv2 License and written in C++17

mipOS: RTOS for micro SoC

Multum In Parvo Operating System is a cooperative multitasking RTOS designed for single-chip micro-controllers with severely limited RAM (e.g. less than 256 bytes) and ROM. It provides the flexibility of an RTOS in low-cost embedded designs.

System-On-Chip (SoC) programmers can choose mipOS for its small, fast and royalty-free benefits.

mipOS manages tasks, providing mutual exclusion, signals, message queues, memory management, timers.
