Ruby, explained in pathways you actually keep.
Luthenoarix writes downloadable guides that teach Ruby programming — one topic per pathway, from your first irb session to a small Sinatra web app. No video, no platform login, no subscription. You pay once and keep the file.
We write Ruby guides, and we're plain about what's in them.
Luthenoarix is a small publisher of PDF guides on Ruby programming. Each pathway is scoped to a specific set of skills — syntax, objects, blocks, testing, and so on — with a table of contents you can check before buying. We don't publish income claims, countdowns, or "limited spots" language, because none of that is true of a PDF file.
Written, not recorded
Every pathway is a written PDF guide with code examples and exercises — built to be read at your own pace and searched later, not watched.
Scoped honestly
Each product page lists the exact modules inside the guide, who it's for, and who it isn't for — before you buy it, not after.
Yours after download
One payment, one file. No login, no recurring charge, no expiring access.
The catalog
Ten pathways, ordered roughly by difficulty. Start with the free one if you're new to Ruby.
What you get with every pathway
Runnable examples
Every concept is shown with real Ruby code you can copy and run, not pseudocode.
Exercises with solutions
Most pathways end each chapter with a short exercise and a worked solution to check against.
No account required
You get a direct download link after payment. Nothing to sign up for, nothing to log back into.
Plain-text pricing
The price you see on the product page is the price you pay — one time, in euros, no add-ons.
Not sure yet? Start with Free Pathway.
It gets Ruby installed and running on your machine, with no payment step at all. If it's useful, the rest of the catalog picks up exactly where it leaves off.
Questions people actually ask
No. Free Pathway assumes nothing and covers installing Ruby and running your first script. From there, each pathway's product page lists a recommended level so you can judge whether it fits where you are.
Every pathway is a PDF file. You can read it on a computer, tablet, or e-reader, and print it if you'd rather work from paper.
Checkout happens on our payment provider's own page — we never see or store your card details. You'll get a download link once the payment is confirmed.
See our refund policy for the specifics. In short: contact us and we'll sort it out.
