A passive network SIGINT console for Linux, written in C99 from the kernel-facing code up. Twenty-seven live ncurses views: 802.11 beacon, probe and deauth sniffing, ARP / mDNS / NBNS / DHCP / SSDP device discovery, TLS ClientHello and JA3 fingerprint capture, and six alert rules for port scans, deauth floods, NXDOMAIN bursts and periodic beaconing. It never injects, never scans and never modifies kernel state — it only watches, and writes JSONL plus a per-alert pcap for whatever comes next.

A real-time 3D Stonehenge that is also a working astronomical instrument, on a hand-rolled Metal 3 renderer with no game engine. Pick any date from the monument's own era to tonight: the sun, moon and nine thousand stars are computed from the published ephemerides, the shadows are tested against an analytic solution to 0.28 m, and every stone traces to cited survey data. Two labelled states — the completed monument of 2200 BC and today's ruin — with an animated four-thousand-year passage between them. Druidic in spirit, archaeological in fact.

Vendor-neutral infrastructure for healthcare contingent labor. Hidden middleman fees skim a few percent off every dollar of travel, per-diem and surgical-tech staffing, and expired credentials cancel surgeries on the day. Crane turns the whole thing into a graph-backed market the provider runs themselves: one posting broadcast fairly to a panel of agencies, submissions gated on live credential compliance, transparent rates, and the fee kept in house — order to panel to award to timesheet to settlement, in integer cents.

Organic-farm recordkeeping for iPhone and iPad: a USDA-sourced plant-cultivar database, grow management, soil-health monitoring with a pH spectrum and lab integration, agricultural lease management with payment tracking, worker time tracking with overtime detection, FDA FSMA harvest-safety checklists, and full traceability of organic amendments — everything an inspector asks to see, already in your pocket. Syncs across your own devices with CloudKit; fully localized in English and Spanish.

Two tones, one in each ear, meet inside a glowing vacuum tube; the beat between them slides through the brainwave bands and lights the chakras. Two band-limited morphing oscillators render straight to the output through a lock-free parameter bridge, and a Metal particle scene draws the same signal as it sounds — the stereo field is the instrument.

Phrase-passwords you can say out loud, drawn from 16,913 embedded cat names, sprinkled with digits and symbols, then scored — five candidates measured with Shannon entropy and a stack of complexity heuristics, and the best one handed to you. Pure C11: a single binary for Linux and macOS with no runtime dependencies, no configuration file and no network. The same idea wearing a very different coat runs as an app — see MeowPass below.

A privacy-first appointment book for solo service providers — the tattoo artists, nail techs, stylists and cleaners whose client list is itself confidential. It is the sole source of calendar truth: it never integrates with the system Calendar, never reaches the network, never enrolls in iCloud, never donates a Siri intent, never indexes to Spotlight. Photos and notes live in an encrypted vault behind an app PIN, with a second per-client PIN for flagged clients and a duress PIN that opens a believable decoy vault when unlock is coerced.

Private, on-device time tracking and Electronic Visit Verification for family caregivers doing self-directed care work. Clock in from a Home Screen widget or a Siri shortcut, log the service performed, take the participant's PIN approval, and export a timesheet PDF for whichever channel the billing provider uses — fax, email, upload or print-and-sign. Daily totals, midnight splits and pay-period arithmetic are done for you; location is captured at clock-in and clock-out only, never in between; and every event is written into a tamper-evident SHA-256 audit chain. No account, no server, nothing shared.

A turn-based historical farming life for iPhone. Inherit a mortgaged quarter-section anywhere from 1930 to today and farm it for thirty seasons against real USDA prices, NOAA weather and the actual farm bills of the era — the almanac, the newspaper, the ledger and the reckoning. No ads, no accounts, entirely on your device.

Live HF propagation, aurora, POTA, SOTA, DX cluster and APRS — plus sun, moon, marine and weather, folded into one brief for exactly where you are. Panels and widgets you arrange yourself, computed on the device rather than fetched from someone else's dashboard.

A native macOS app that turns freelance client work into a stage-gated practice: leads from Fiverr, Twine, LinkedIn and referral move through qualification, a written scope with explicit out-of-scope, a deposit before build, signed-off requirements, change requests priced against the original, a clean handoff, and a close-out that asks for the testimonial and the portfolio permission. CRM and billing sit in local SQLite; specs and proposals stay plain Markdown you can grep, edit anywhere and hand to an agent. Billing is imported exactly from append-only ledgers — never estimated.

A native macOS app that models the software system a repository represents — not its files — as a knowledge graph built from literal repository evidence, then renders it as a pattern visualizer: cycles, coverage, callers and architectural roles in one view. The graph is append-only and content-addressed, so every fact keeps its provenance and every revision can be replayed. Analysis runs entirely on your machine.

The native app the command-line generator grew into, in a Shōwa-era game-show register. It does three things: conjures five sayable passwords from a thousand-odd cat names and crowns the one with the best complexity score; judges any password you paste, nought to ten, with a verdict somewhere between "a kitten could paw this open" and "fur-midably complex"; and composes a MeowGram — a secret note tucked invisibly inside an ordinary cat photo with DCT steganography, optionally sealed with a ChaCha20-Poly1305 passphrase. There is an iMessage extension for sending them and a share extension for decoding them. No accounts, no servers, no tracking; the Android build ships without the network permission at all.

A real-world, soil-first companion for corn farmers — the practical sibling of the Corn 3000 game. Map fields on satellite imagery, auto-detect the soil from USDA SSURGO and ISRIC SoilGrids, follow a proper soil-sampling guide and record the lab results, track the season by growing-degree days to the current corn stage, and read a caveated yield outlook that is a range, never a promise. Then project ten years of organic matter, pH and soil life under cover crops, reduced tillage, manure and rotation. Every survey number wears an "estimated" badge; a lab test always wins. On-device, offline, no account.

A mobile-first maintenance suite for small landlords and the tradespeople who keep their rentals running, named for the Purple Martin. The handyman clocks time against a property, attaches photos and notes, keeps a materials list and records expenses with receipts; the owner approves time and money and assigns repair tickets; a resident reports a problem with photos and watches it move. Offline is a first-class state on every device, the server is a single docker compose up on your own Linux box, approval locks are enforced server-side, and the same container answers a browser with a zero-JavaScript manager's desk. iOS and Android at strict parity, with no third-party dependencies on either.

A stylized 3D space trading game in which hyper-intelligent cats run a galactic cat-food empire. Sign on as a cat, take delivery of a mortgaged Loaf-class heavy freighter, and work the load board across a shared, server-run Sol system where every price is a pure function of station stock and every flight is priced off where the planets actually are tonight. The universe runs on five-minute ticks: book a haul, put the phone away, and a notification calls you back for the delivery wire. Deterministic integer simulation, a custom Metal renderer built for Apple GPUs, and a server that proves its own history. Nothing is scripted, including the mortgage.

The caregiver's own record of care, built for Arizona's DDD, PPCG, SDAC and VDC programs. A one-tap shift timer splits at midnight and rolls up into shift blocks. Each shift records the tasks done, not only the hours. At the end of the pay period the app produces a signed PDF timesheet and a care summary that a parent can hand to a fiscal agent or bring to a reassessment. CareTally is not an EVV vendor. It sits beside the agency's mandated app and records what that app does not. It runs entirely on the phone: no account, no cloud, no tracking, and no network code in the binary at all.

An iOS instrument: a drone, a ring of intervals against that drone, and a round phosphor scope in the middle that draws the two as a Lissajous figure. The ring is a step sequencer whose hand goes around once every 8 to 240 seconds, never in beats per minute. Each step stores its interval as an integer ratio against the drone, so turning the drone moves every step with it. Hold the ring between steps and it becomes a continuous-pitch manual. The scope is the tuner: an exact ratio draws a closed figure, and anything else tumbles at a rate the marquee prints. Same tube, same brass and same audio core as Nighthawk Tube, with no chakras, no planets and no presets that name a chart. Ratios only.

The Megalithic Construction Set. Pick any place on Earth, stand on its real terrain under its real horizon, and raise your own monument from real rock types and megalithic presets in a full 3D edit mode. Then read which solar, lunar and stellar alignments the layout you built actually catches, for any epoch. Every bearing comes out of the ephemeris and a fetched heightfield, never out of a designer's opinion, and no document ever stores an "aligned" flag: alignment is computed when you ask, for the stone where it stands now. A sibling of Henge, forked from it in September 2026. Henge's monument is fixed and its latitude is pinned. Megalith's are yours.

An artificial-life game about the evolution of cooperation. Hundreds to thousands of particle agents forage, meet, share, take, punish, breed and die in a toroidal world. No strategy is hard-coded to win: sharing, taking, kin favouritism, reciprocity and retaliation each rise or collapse under conditions the player sets. Every slider maps to a variable the literature identifies as decisive, and every campaign scenario reproduces one published result. A world is a config plus a seed and replays tick for tick, forever. The simulation drives the synth directly, on the oscillator core from Nighthawk. No moral frame, no colour that judges, no hidden bonus for being nice.
