Day three of THE BOARD already names what kills it: about a third of you have got shell accounts now and are not calling any more, and i do not blame you, because it is better, it is genuinely better. The player never got to see it. Now they do, immediately afterwards, while the board's ghost is still warm. kruuna.helsinki.fi, 1991. It connects instantly, with no dial tone, no ring and no busy signal, and that silence after eight minutes of the board is the whole opening beat. who(1) shows the people who are on the machine at this second, against a board that had forty-four users in nine years and could hold one at a time. talk(1) puts every character on screen as it is typed, because that is what talk did. And make compiles a kernel in the top four lines while you carry on using the shell underneath it — two things at once, demonstrated rather than stated, which the board could never do. Then the interjection. rms has been on ttyp7 since six in the morning. He waited until the level printed a whole operating system over a build log in which every single line is gcc, and then he opened a talk request, and he is right. If you never answer it he leaves mail instead, because of course he does. The closing speech now credits the compiler, the linker, the shell, make and libc, which were all finished and free years before the kernel was. 74 philes. All 14 hops swept clean.

# HANDSHAKE
|
||
|
||
> *a love story in 64 hops*
|
||
|
||
You are **SYN**. You want **ACK**. Root is the only one who can give it to you.
|
||
|
||
Design doc: [DESIGN.md](DESIGN.md).
|
||
|
||
## Run it
|
||
|
||
```bash
|
||
python3 /Users/johnking/Documents/handshake/serve.py 8123
|
||
```
|
||
|
||
Then open `http://localhost:8123/`. Headphones — every frequency in this is the real
|
||
frequency and half the mechanics are inaudible without them.
|
||
|
||
`serve.py` is `http.server` plus `Cache-Control: no-store`, because ES modules cache
|
||
hard and it makes every edit look like it did nothing.
|
||
|
||
## Controls
|
||
|
||
| | |
|
||
|---|---|
|
||
| `WASD` | move |
|
||
| `SPACE` | jump / hold 2600 Hz |
|
||
| mouse | look (click to capture; dragging works too) |
|
||
| `E` | use |
|
||
| `M` | traceroute — the level select, and where you drop cargo |
|
||
| `P` | philes — read what you've picked up |
|
||
| `` ` `` | hop select (dev) |
|
||
| `ESC` | release the mouse |
|
||
|
||
It saves. Every hop completes a handshake with the world and writes to
|
||
localStorage; the boot screen offers `R — RESUME` when there's something to resume.
|
||
|
||
## What's here
|
||
|
||
Fourteen playable hops, each a different genre, one renderer.
|
||
|
||
| id | hop | what it is |
|
||
|---|---|---|
|
||
| `coldboot` | 1 | FP tutorial in a 512-slot NIC ring buffer, then the DMA rips you out |
|
||
| `stack` | 2–8 | 7-floor descent, **one verb per layer**: transcode, keep the session, reassemble in sequence, route within a hop budget, listen-before-transmit with real exponential backoff, ride the waveform. Stateful FIREWALL boss |
|
||
| `timewait` | 9 | walking sim. beige room, 50 Hz hum, half-open connections in plastic chairs, FIN by the door |
|
||
| `war` | 10–16 | EFnet twin-stick. netsplit riding, ops crowns, and a **trojan arms race** — four weapons the level patches 70 s after you first use one |
|
||
| `smash` | 17–20 | 2D side-scroll `char buf[64]`. canary, return address, NOP sled, shellcode — then **NX lands** and you build a **ret2libc** chain out of other people's platforms |
|
||
| `worm` | 21–28 | Morris worm RTS, 1-in-7 reinfection locked on. An **antidote you can release** that travels only over live links, while you are killing links |
|
||
| `cuckoo` | 29–34 | LBL 1986 terminal. connection time is visibility. you get caught |
|
||
| `board` | 35–44 | the BBS, over **three days**. busy signal, ANSI painting at live baud, ratios, NUP gate, ANSI bomb, the sysop watching you type, FidoNet, playable LORD *and* Trade Wars — then LAST CALL, and it closes |
|
||
| `shell` | 43–44 | kruuna.helsinki.fi, 1991. always on, 38 users at once, talk(1) character by character, the comp.os.minix post, and a kernel compiling in the background while you use the shell |
|
||
| `handshake` | 45–50 | five-boss rhythm arena. dial tone → DTMF → ANSam → V.8bis → carrier |
|
||
| `copper` | 51–58 | FP through duct, load coils, a Strowger cathedral, a lineman's handset |
|
||
| `bluebox` | 59–63 | playable 13-button blue box. 2600, KP/MF/ST, tandem stacking, then SS7 |
|
||
| `climb` | 63→1 | on-rails reverse ascent, **one gate per era** testing the verb it taught you. Spectre is a real **split screen**, plus Rowhammer and Log4Shell |
|
||
| `root` | 64 | the room is empty. then the ACK comes back — and on Tuesday, so does your FidoNet message |
|
||
|
||
## The three load-bearing ideas
|
||
|
||
**TTL is the health bar and it only goes down.** 64 hops, no healing, ever. Levels
|
||
aren't hard, they're *expensive*.
|
||
|
||
**Bandwidth is resolution** — [`src/link.js`](src/link.js). One render target and one
|
||
shader. Your baud rate sets the target height; at 1200 and below the scene renders as
|
||
ASCII glyphs. `HS.link.setBaud(0..6)` in the console to see it. The V.8bis fight sets
|
||
this for real.
|
||
|
||
**Every header you drop is a piece of clothing** — `makeSyn()` in
|
||
[`src/kit.js`](src/kit.js). Seven wireframe shells, one per OSI layer, shed as you
|
||
descend.
|
||
|
||
## MTU
|
||
|
||
Files taken off the BBS are lore, and lore is paid for in distance. Two is free;
|
||
after that you don't fit down the next hop in one piece and every hop costs a TTL
|
||
per extra fragment. You can put things down again from the traceroute map. That's
|
||
the whole economy: everything worth reading costs you some of the distance you have
|
||
left.
|
||
|
||
## Audio
|
||
|
||
[`src/audio.js`](src/audio.js) — every tone is oscillators, nothing is sampled, and
|
||
every frequency is the real one: 350+440 dial tone, the DTMF matrix, R1 MF pairs with
|
||
real 100 ms KP / 60 ms digit timing, 2600 Hz, ANSam at 2100 Hz reversing phase every
|
||
450 ms, Bell 103 FSK. About 300 lines and zero megabytes.
|
||
|
||
## Layout
|
||
|
||
```
|
||
index.html shell, all CSS, importmap
|
||
serve.py dev server, no-store
|
||
src/main.js router, TTL, traceroute map, the loop
|
||
src/link.js bandwidth → resolution. the post shader.
|
||
src/audio.js every tone in the game
|
||
src/term.js 80x25 cell terminal, pipe colours, CP437 blocks as geometry
|
||
src/kit.js body/collision, camera rigs, SYN, labels, seeded rng
|
||
src/input.js keys, pointer lock, the ANSI bomb's remap table
|
||
src/hud.js status line, subtitles, title cards, NO CARRIER
|
||
src/levels/*.js one file per hop
|
||
vendor/ three.js r17x, vendored
|
||
```
|
||
|
||
Each level exports `{ id, hop, title, via, baud, mount(ctx), update(dt,t,ctx), unmount(ctx) }`.
|
||
`ctx` hands it a fresh scene, camera and collision world, plus `say/card/hint/phile/
|
||
spendTTL/setBaud/next`. Genre switches are just different camera + controller modules
|
||
over one renderer — that's the whole trick.
|
||
|
||
## Dev handles
|
||
|
||
`HS` on `window`: `HS.goto(id)`, `HS.link.setBaud(n)`, `HS.game`, `HS.philes`,
|
||
`HS.run(n)` — drives `n` frames by hand, because `requestAnimationFrame` is throttled
|
||
to zero in a hidden tab and that makes the game look broken when it's only asleep.
|
||
|
||
## Skipped
|
||
|
||
- **Multiplayer (`CHECKSUM`)** — the Journey-style anonymous pass-by. Needs a server; add when there's something to connect to.
|
||
- **Playing both fragments** — fragmenting costs TTL, it doesn't split you into two packets you alternate between. Add when a level has a corridor narrow enough to need it.
|
||
- **The 200 philes** — 74 written in [`src/philes.js`](src/philes.js), all readable with `P`. Adding the next 126 is a writing job, not a code job: put the text in that file, call `ctx.phile('id')` wherever it should be found.
|
||
- **Era-generated music** — the design doc says each level's pad is built from that era's protocol. Right now they're chords.
|
||
- **The retrain** — a mid-game renegotiation that drops your baud without warning. One system, touches every level after it.
|
||
- Levels run 3–8 minutes against a design doc that asks for 5–20. The genres, mechanics and set pieces are all in — the *duration* is still short. See [STAGES.md](STAGES.md) for a per-hop breakdown of what's in and what's next.
