Hi, I'm Markzz

I build lightweight, dependency-free software for Termux, Android, and the terminal.
If it needs a 400 MB runtime, it probably doesn't need to exist.

up 2 years — building NoNameOS, Grub Blasters, and whatever scratches the itch.

• pkg-manager v5.2 — live package-info preview panes, a not-installed-only install list with a pre-flight batch summary, uninstall's own finder, ESC that cancels everywhere, and a numbered text mode that takes over (with an explanation) if fzf ever breaks.

• Every palette checked against its source — Nord, Dracula, Catppuccin, Tokyo Night, Gruvbox, One Dark, Solarized, Everforest and Rosé Pine are now hex-verified against the upstream projects, and every titled legacy theme (blue/green/teal…) actually shows the color it names.

• NoNameOS gained real sha256sum/stat commands plus a piped-REPL smoke suite, Plusalator gained memory slots, angle units and output radix modes, and Android9-audios ships per-file checksums with a verify script.

• Still refusing to install a 400 MB runtime.

• 🔭 Building — expanding NoNameOS, a single-file C++17 OS simulation

• 🌱 Exploring — low-level Android internals, TUI design, and game loops

• 🧠 Belief — the best dependency is the one you never installed

• 😗 Fun fact — I rooted a TV stick and reclaimed 1.9 GB of storage

Worms-style turn-based artillery in a single dependency-free HTML file. 2–4 teams blast each other across procedurally generated, fully destructible terrain with 60 weapons (bazooka to banana bomb), a fuel-limited jetpack, floating islands, CPU opponents, shifting wind, a rising sea, and hot-seat multiplayer.

No dependencies. No build step. One file, any modern browser, desktop or phone.

fzf-driven interactive package manager for Termux — a friendlier face for pkg/apt without touching the raw commands. 59 menu entries, 16 themes, live package-info preview panes, automated backup/restore, package pin/hold, a system-audit health score, SHA-256-verified self-update, and a scriptable CLI (--check-updates, --quiet, --doctor) — 175 hermetic tests.

A complete OS simulation in one C++17 file. Interactive shell, virtual filesystem, built-in utilities, and games — zero external dependencies. Single-file architecture, self-contained complexity, and a genuinely fun way to learn systems concepts.

Screenshot from an earlier build — the current version is far more feature-rich.

A modern, visually stunning Snake game for your terminal — Python + Textual. Neon gradients, particle bursts, combo multipliers up to x5, power-ups (Speed, Slow, Ghost, Frenzy, Magnet), golden apples, five themes, three difficulties, and a persistent local leaderboard, all in pure Unicode blocks.

Cinematic effects — glow, screen shake, floating score popups — with a layout that adapts to your terminal.

A feature-rich, visually rich modern HTML calculator with 15 themes plus a System mode (Tokyo Night, Catppuccin, Gruvbox, Nord, Dracula…), scientific functions, memory registers, a history tape with CSV export, a ? shortcut overlay, keyboard shortcuts, and full responsiveness — all in a single dependency-free page.

Fancy interactive C++17 calculator REPL for Termux — standard library only, single binary. Qalculate-flavored engine: postfix percent (%), right-assoc ^ (-2^2=-4), implicit multiplication, user functions with depth-capped recursion, and fuzz-gated so it never crashes. Ghost autosuggest, transient prompt with ⟨ plusa ⟩ ➤ ornament, 18 truecolor palettes, memory slots (ms/mr/m+), angle units (deg/rad/grad), and output radix modes (mode hex|bin|sci) — 114 assertions in the test gate.
