SYS://LNHUB Developer hub / public index
Notes on things I do and independent projects that keep their own host. The goal is simple: keep useful technical context easy to find later.
00 About the hub
I’m Luciano. I build software, run infrastructure, and experiment with small systems. This site is the durable layer above scattered repositories, notes, bookmarks, and debugging sessions.
When something is worth keeping, I write it down. When it is useful as a page, it lives here. When it is a complete independent work, it keeps its own host and this hub points to it.
01 Notebook
Things I did, discovered, or took apart — from a small note in the day to a longer write-up of a project.
fatturapa is a dependency-free TypeScript library I wrote so a B2B marketplace can issue Italian electronic invoices for its sellers. You pass amounts in integer cents; it computes the totals the way SDI recomputes them, reports every problem SDI would reject in one go, and returns the FatturaPA XML with its file name.
02 Independent hosts
Bigger work with its own domain and stack. A game on futurevector.org belongs here. A page on this hub does not.
01 / 04 A live duel. Both fighters play themselves; the tiles on the sides show health, abilities and traits as they trigger.
orbvora.com
A free browser auto-battler. Build a spherical fighter, then watch the server run the duel on a timeline every viewer shares. No download, no account required.
03 Hub map
Writing stays in the notebook. Projects keep their own host. Personal context and contact sit apart from the work.

04 Placement rule
A note belongs in the blog. A complete independent system keeps its own host and is listed as a project.
