# Urbit
|
||||
|
||||
Urbit is a clean-slate system software stack defined as a
|
||||
deterministic computer. An encrypted P2P network, `%ames`, runs on a
|
||||
functional operating system, Arvo, written in a strict, typed
|
||||
functional language, Hoon, which compiles itself to a combinator
|
||||
interpreter, Nock, whose spec gzips to 340 bytes.

which the Internet can't easily address. Programming for a
|

deterministic single-level store is also a different experience from
|

Unix programming, regardless of language.

||||
## Getting involved
|
||||
|
||||
Urbit is designed to run on any Unix box with an internet connection. Debian
|
||||
(jessie), OS X, FreeBSD and Fedora all work well.
|
||||
If you're interested in following Urbit, you can:
|
||||
|
||||
Urbit is alpha software. It’s not yet completely stable, its crypto hasn’t
|
||||
been audited, and there are plenty of rough edges. Urbit is lots of fun to play
|
||||
with, but not quite ready for your important or sensitive data.

## Build from source
|
||||
## Code of conduct
|
||||
|
||||
Everyone involved in the Urbit project needs to understand and respect
|
||||
our code of conduct, which is: "don't be rude."
|
||||
|
||||
# Install
|
||||
|
||||
Urbit can be installed on most Unix systems. There is no Windows port.
|
||||
Windows is a wonderful OS, we just haven't gotten to it yet. Use a VM.
|
||||
|
||||
## Configure swap if needed
|
||||
|
||||
Urbit wants to map 2GB of memory when it boots up. We won't necessarily
|
||||
use all this memory, we just want to see it. On a normal modern PC or
|
||||
Mac, this is not an issue. On some small cloud virtual machines (Amazon
|
||||
or Digital Ocean), the default memory configuration is smaller than
|
||||
this, and you need to manually configure a swapfile.
|
||||
|
||||
To add swap to a DO droplet, [read
|
||||
this](https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-14-04).
|
||||
To add swap on an Amazon instance, [read
|
||||
this](http://stackoverflow.com/questions/17173972/how-do-you-add-swap-to-an-ec2-instance)
|
||||
|
||||
Don't spend a lot of time tweaking these settings; the simplest thing is
|
||||
fine.

only work on Stretch; I wish we knew why; help us!)

### Setting up swap
|
||||
### Download and make
|
||||
|
||||
Urbit wants to map 2GB of memory when it boots up. We won’t
|
||||
necessarily use all this memory, we just want to see it. On a
|
||||
normal modern PC or Mac, this is not an issue. On some small
|
||||
cloud virtual machines (Amazon or Digital Ocean), the default
|
||||
memory configuration is smaller than this, and you need to
|
||||
manually configure a swapfile.
|
||||
Clone the repo:
|
||||
|
||||
Digital Ocean has a post on adding swap [here](https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-14-04). For Amazon there’s a StackOverflow thread [here](http://stackoverflow.com/questions/17173972/how-do-you-add-swap-to-an-ec2-instance).
|
||||
git clone https://github.com/urbit/urbit.git
|
||||
|
||||
Don’t spend a lot of time tweaking these settings; the simplest
|
||||
thing is fine.
|
||||
`cd` to the directory you just created:
|
||||
|
||||
### Clone and make
|
||||
|
||||
Once your dependencies are installed the rest is easy:
|
||||
|
||||
git clone https://github.com/urbit/urbit
|
||||
cd urbit
|
||||
|
||||
Run `make`:
|
||||
|
||||
make
|
||||
curl -o urbit.pill https://bootstrap.urbit.org/latest.pill
|
||||
|
||||
After running `make`, your Urbit executable lives at `bin/urbit`. The `.pill` file is a compiled binary of Arvo that Urbit uses to bootstrap itself.
|
||||
(On FreeBSD, use `gmake` instead.)
|
||||
|
||||
# Getting started
|
||||
The executable is `bin/urbit`.
|
||||
|
||||
On disk your Urbit is an append-only log and a checkpoint. Or, in simpler terms, a directory where we keep all of your Urbit’s state. We call this a ‘pier’.
|
||||
Fetch the latest bootstrapping pill:
|
||||
|
||||
## Initialize
|
||||
curl -o urbit.pill http://bootstrap.urbit.org/latest.pill
|
||||
|
||||
When you first start an Urbit we create this pier directory and write to it.
|
||||
You can use your preferred way to fetch things from the web here. Urbit
|
||||
looks for a pill named `urbit.pill` in the current directory by default,
|
||||
so if you have anything different, you'll need to tell Urbit where it is
|
||||
(on first launch only) with the `-B` command-line option.
|
||||
|
||||
To start with a planet (`~fintud-macrep`) and ticket (`~fortyv-tombyt-tabsen-sonres`):
|
||||
# Start
|
||||
|
||||
bin/urbit -w fintud-macrep -t fortyv-tombyt-tabsen-sonres
|
||||
An urbit is a persistent server on the `%ames` P2P network. You'll
|
||||
create one of these servers now.
|
||||
|
||||
This will create a directory `fintud-macrep/` and begin the initialization process for that planet. Be patient, it can take a few minutes.
|
||||
If you have an invitation, it's a planet like `~fintud-macrep` and a
|
||||
ticket like `~fortyv-tombyt-tabsen-sonres`. Run
|
||||
|
||||
Without a planet anyone can create a comet:
|
||||
urbit -w fintud-macrep -t fortyv-tombyt-tabsen-sonres
|
||||
|
||||
bin/urbit -c comet
|
||||
(You can leave the `~` on, but it annoys some Unix shells.)
|
||||
|
||||
This will create a directory `comet/` and start up a random 128-bit comet. You can specify any name you like.
|
||||
If you don't have an invitation, pick a nickname for your comet, like
|
||||
`mycomet`. Urbit will randomly generate a 128-bit plot:
|
||||
|
||||
## Orientation
|
||||
urbit -c mycomet
|
||||
|
||||
When your Urbit is finished booting you should see a `dojo>` prompt. Welcome!
|
||||
Either way, creating your urbit will take some time. Some of this time
|
||||
involves creating keys; some of it involves downloading code over Urbit
|
||||
itself. Go get a cup of coffee. Or a beer.
|
||||
|
||||
By default your Urbit is quite bare bones. Let's take a very short stroll through what's running by default:
|
||||
Wait until you see a prompt, something like
|
||||
|
||||
### Shell — `:dojo`
|
||||
~fintud-macrep:dojo>
|
||||
|
||||
The command prompt in front of you is a simple shell and Hoon REPL. Let's make sure it works:
|
||||
Your urbit is launched! Ladies and gentlemen, we are floating in space.
|
||||
|
||||
~fitund-macrep:dojo> (add 2 2)
|
||||
In either case you'll notice that we created a directory in unix called
|
||||
either `mycomet` or `fintud-macrep`. All of your state (a log and
|
||||
checkpoint) lives in that directory. You can move it around, but don't
|
||||
delete it!
|
||||
|
||||
Should produce:
|
||||
### Restarting
|
||||
|
||||
> (add 2 2)
|
||||
4
|
||||
If you want to shut your Urbit down you can `^d` from the `dojo>`
|
||||
prompt. To use Urbit normally after creating your planet or comet
|
||||
there's no need for the `-w -t` or `-c` options.
|
||||
|
||||
Good.
|
||||
Instead:
|
||||
|
||||
### Messaging — `:talk`
|
||||
urbit fintud-macrep
|
||||
|
||||
Use `^X` to change your prompt. Let's join the main Urbit chat channel:
|
||||
or
|
||||
|
||||
~fitund-macrep:talk() ;join ~doznec/urbit-meta
|
||||
urbit mycomet
|
||||
|
||||
This may take a bit as `:talk` is stateful so your Urbit will download some backlog. `/urbit-meta` is the place to ask questions, get help and talk about anything Urbit related.
|
||||
### Continuity breaches / network reboots
|
||||
|
||||
### Web — `:tree`
|
||||
Urbit is still young, and we reboot the network from time to time. Urbit
|
||||
can upgrade itself over the air, but at this stage it's easier to bring
|
||||
in breaking api changes this way. Since our crypto is stateful we call
|
||||
this a 'continuity breach'.
|
||||
|
||||
Urbit is also accessible through the web. Try opening:
|
||||
If you have files in your Urbit you'd like to backup first make a copy
|
||||
of your pier. Then you'll need to shut down your urbit (with `^d`) and:
|
||||
|
||||
http://localhost:8080/
|
||||
git pull origin master
|
||||
make clean; make
|
||||
curl -o urbit.pill http://bootstrap.urbit.org/latest.pill
|
||||
|
||||
in your favorite browser. You'll be prompted to use `+code`. This page was generated by `:tree`, the basic Urbit web interface. You can also access your Urbit through `http://fintud-macrep.urbit.org` (where `fintud-macrep` is your planet name).
|
||||
Then start over at the top of this section.
|
||||
|
||||
### Filesystem — `%clay`
|
||||
# Talk
|
||||
|
||||
`%clay`, the Urbit filesystem, isn't mounted to unix by default. Switch to the `:dojo` prompt and run:
|
||||
We use Urbit to talk to each other and coordinate about building the
|
||||
system. To join the main Urbit talk station use `^x` to switch to the
|
||||
`talk()` prompt, then run:
|
||||
|
||||
~fitund-macrep:dojo> |mount %
|
||||
;join ~dozbud/urbit-meta
|
||||
|
||||
This should produce:

||||
`|mount %` will cause a `home/` directory to appear inside your pier folder. Changes to these files are automatically synced into your Urbit.
