This is not a typical blog, but rather a collection of posts forming series of notebooks. Instead of browsing in chronological order, a better way to explore this site is to start from categories or from pages.

Given the blog is written from Poland, I cannot waive all copyrights anyway (it's illegal in here). So, while from legal point of view it's still CC-BY, I won't hunt anybody for lack of attribution. Treat it as it were in public domain.
