Bazaar

✦ The bazaar is where the things I build get sold: one-time purchases, delivered the moment payment clears, no accounts.

Four stalls:

Each stall’s page carries a heading per listed item — a small brief of what it is and why it’s worth money.

Everything sold is original work, scout-cleared for licensing before it ships. The rationale: recoup the server and domain running costs by selling genuinely useful things, rather than by running ads.

The storefront’s white-gold aesthetic is documented in the Icons page — the favicon is a milky-marble orb whose golden streamlines are trajectories of a two-vortex dynamical system, with the site’s curved diamond ✦ sitting at the sink where all influence collects.

Bazaar: reMarkable

Native plugins for the reMarkable Paper Pro and the Paper Pro Move, built against real firmware and sold at bazaar.abaj.ai/remarkable. Everything runs under xovi / rm-appload rather than patching the system: no bank-flip risk, graceful degradation on firmware updates, and every item version-pinned to the firmware it was tested on.

Nearly every item on this shelf now ships for both devices — each product page has a device picker (Paper Pro / Paper Pro Move), and the Move builds are packaged from the exact files proven on real Move hardware. The handful of exceptions (the Move builds of FastTerm, the GUI Emacs and laserPen — the first two need a keyboard story the Move doesn’t have) say so plainly on their pages.

Bazaar: Notes

Typeset study bundles — LaTeX-set PDFs of my own summaries — sold at bazaar.abaj.ai/notes. The gate for this stall is the strictest in the bazaar: only 100%-own-authorship summaries, no lecturer material, course branding stripped. Free counterparts live across the site’s typeset-PDF wiki pages; the paid bundles are the ones polished into standalone books.

STAT 571 — Probability & Measure

My course notes from the University of Alberta’s graduate probability-and-measure course: a ~50-page arc from sigma-fields to the ergodic theorem — Carathéodory extension, the convergence theorems, Fubini–Tonelli, L^p, Borel–Cantelli, LLN, CLT — thirteen lectures compressed to revision speed. I write my own notes for every course I take; these ship with the custom LaTeX preamble (Baskervaldx + newtxmath, the theorem environments) so yours can look this good too.

Bazaar: Flashcards

Hand-authored Anki decks, exported clean and sold at bazaar.abaj.ai/flashcards. The rule for what gets sold: only decks that are my own words — anything derived from textbooks, publisher audio, or downloaded shared decks stays out of the shop (sourcing rules in the bazaar repo’s SPEC §7). All four are in pre-sale cleanup: verbatim third-party fragments get stripped before any deck ships.
