TChannel can return many different types of errors when making requests and
sending responses.

## TChannel Client Errors

As part of http state machine integration, tchannel errors need be mapped to
proper http status codes/messages so that http clients can differentiate errors
and possibly take some actions.

A list of tchannel errors defined at protocol level:
[section payloads.error.code `protocol.md`](protocol.md)

A list of http status code/message:
[https://en.wikipedia.org/wiki/List_of_HTTP_status_codes]

The proposed mapping is:

| code   | name                 | http status code/message
| ------ | -------------------- | -------------------------
| `0x01` | timeout              | 408 Request Timeout
| `0x02` | cancelled            | TBD
| `0x03` | busy                 | 429 Too Many Requests
| `0x04` | declined             | 503 Service Unavailable
| `0x05` | unexpected error     | 500 Internal Server Error
| `0x06` | bad request          | 400 Bad Request
| `0x07` | network error        | TBD
| `0x08` | unhealthy            | 503 Service Unavailable
| `0xFF` | fatal protocol error | TBD

_1st-level abjuration_

**Casting Time:** 1 reaction, which you take when you are hit by an attack or targeted by the _[magic missile](../magic-missile/)_ spell
**Range:** Self
**Components:** V, S
**Duration:** 1 round

An invisible barrier of magical force appears and protects you. Until the start of your next turn, you have a +5 bonus to AC, including against the triggering attack, and you take no damage from _[magic missile](../magic-missile/)_.

Enable or disable bluetooth on OS X based on your current location

## Why?

I use bluetooth on my Mac at the office for my wireless keyboard and mouse. At home or at the coffee shop, however, I don't use bluetooth at all. So bluetooth is generally running, and:

* draining my battery
* interfering with my wireless connection

until I remember to turn it off. And then, of course, I have to turn it back on at the office.

Bluemoon will handle powering your MacBook's bluetooth connection based on your location.

## Installation

I'm currently working on a homebrew recipe. Until then:

```
brew install blueutil
brew install sleepwatcher
brew install terminal-notifier
gem install bluemoon --no-wrappers
```

## Configuration

You'll probably want `bluemoon bootup` to run everytime you reboot:

```
crontab -e
@reboot bluemoon bootup
```

To be useful, you'll need to add at least one location you want Bluetooth enabled.

```
bluemoon add # current location
```

## TODO

* Add IP address or router Mac address support
* Create a homebrew recipe
* Vendor `get-location` properly so it installs without the `--no-wrappers` flag
* Create a homebrew recipe so `brew install bluemoon` works

## Acknowledgements

The [get-location helper](https://github.com/lindes/get-location) was created by [@lindes](https://github.com/lindes).  Thank you.

[@jonahaaron](https://github.com/jonahaaron) proposed IP-address support.

  This is the chip-specific code for many 8390-based ethernet adaptors.
  This is not a complete driver, it must be combined with board-specific
  code such as ne.c, wd.c, 3c503.c, etc.

  Seeing how at least eight drivers use this code, (not counting the
  PCMCIA ones either) it is easy to break some card by what seems like
  a simple innocent change. Please contact me or Donald if you think
  you have found something that needs changing. -- PG

  Changelog:

  Paul Gortmaker	: remove set_bit lock, other cleanups.
  Paul Gortmaker	: add ei_get_8390_hdr() so we can pass skb's to
			  ei_block_input() for eth_io_copy_and_sum().
  Paul Gortmaker	: exchange static int ei_pingpong for a #define,
			  also add better Tx error handling.
  Paul Gortmaker	: rewrite Rx overrun handling as per NS specs.
  Alexey Kuznetsov	: use the 8390's six bit hash multicast filter.
  Paul Gortmaker	: tweak ANK's above multicast changes a bit.
  Paul Gortmaker	: update packet statistics for v2.1.x
  Alan Cox		: support arbitrary stupid port mappings on the
  			  68K Macintosh. Support >16bit I/O spaces
  Paul Gortmaker	: add kmod support for auto-loading of the 8390
			  module by all drivers that require it.
  Alan Cox		: Spinlocking work, added 'BUG_83C690'
  Paul Gortmaker	: Separate out Tx timeout code from Tx path.

 *	SMP and the 8390 setup.
 *
 *	The 8390 isn't exactly designed to be multithreaded on RX/TX. There is
 *	a page register that controls bank and packet buffer access. We guard
 *	this with ei_local->page_lock. Nobody should assume or set the page other
 *	than zero when the lock is not held. Lock holders must restore page 0
 *	before unlocking. Even pure readers must take the lock to protect in
 *	page 0.
 *
 *	To make life difficult the chip can also be very slow. We therefore can't
 *	just use spinlocks. For the longer lockups we disable the irq the device
 *	sits on and hold the lock. We must hold the lock because there is a dual
 *	processor case other than interrupts (get stats/set multicast list in
 *	parallel with each other and transmit).
 *
 *	Note: in theory we can just disable the irq on the card _but_ there is
 *	a latency on SMP irq delivery. So we can easily go "disable irq" "sync irqs"
 *	enter lock, take the queued irq. So we waddle instead of flying.
 *
 *	Finally by special arrangement for the purpose of being generally
 *	annoying the transmit function is called bh atomic. That places
 *	restrictions on the user context callers as disable_irq won't save
 *	them.
