Notes that became guides.
Korvixalix is a small, independent publisher of PDF guides to Ruby programming. We don't have a course platform, a certificate, or a community forum — just guides, written to be read once and kept as reference.
Where this started
The first guide we wrote was for two colleagues learning Ruby on the job. Most tutorials we found either assumed too much or padded simple ideas into long chapters to look substantial. We wrote something shorter and more direct instead, and kept doing that as the topics got harder.
What we actually sell
Ten PDF guides, priced individually, covering Ruby from installing the interpreter through to its object model and concurrency primitives. Nothing is bundled behind a subscription, and nothing is sold on urgency — the catalogue looks the same today as it will next month.
What we don't promise
We don't promise a job, a salary figure, or a timeline for "becoming a Ruby developer." What each guide promises is narrower and more honest: a specific set of topics, explained clearly, with working code you can run yourself.
How the guides are written
Every guide starts as working code, not prose. We write and test the examples first, then write the explanation around them. If an example doesn't run cleanly on a current Ruby release, it doesn't go in the guide.
