The header is used to sign request parameters, including the parameters 
of the OAuth header.

The handshake is a multi-step process to get a user's credentials: 
request a temporary token, send the user to the site, user comes 
back and enters a code, request a permanent token.

That's all there is to it : )

Yeah ... I looked at this before and decided it was a little tricky 
:)

A more generic implementation may be a protocol that wraps around 
http(s).

sounds like a good idea :)

Doable, I think.  Need to have a way to store user info over sessions.

system/user ?

I think that's fine if it's for your own purposes...

as opposed to ?

Well, even for twitter, I maintain an account for my soccer team 
- so I have an app key/secret and two user key/secrets.

Then for google, you'd need an app key/secret and a user key/secret.

So you'd need to store by domain and user.

I see ...

api.twitter.com
 [
    "rgrebol" [
         key/secret/other metadata
    ]
]

docs.google.com
 [...]

And...

api.twitter.com
 [key/secret]
docs.google.com
 [key/secret]

get-env returns the value of an env variable, so you could concat 
that, system32, and the dll name

replace the lib loading line with this:


k32-lib: load/library join to-file get-env "systemroot" %"/system32/Kernel32.dll"

it works for me

does it work for you?

not quite - the correct path is still prefixed with the directory 
of the rebol exe

** Access Error: Cannot open /C/dev/r2/C:\Windows/system32/Kernel32.dll
** Near: k32-lib: load/library join to-file get-env

need a leading "/" to make it an absolute path, no?

oops... to-file should be  'TO-REBOL-FILE

OK, now

ok, will update rebol.org file.

I get:

you are not using the latest rebol which has library support for 
free.

2.7.7 or higher?

2.7.7

core or view?   AFAIK only the view version has the library support.

Library support requires /View for now, not /Core.

that was core - with view, it works

what was the reason for limiting it to /View?

It was limited to /View before. That limitation was just not removed 
yet. 2.7.7 was put out quickly.

I get significantly varying results from consecutive executions of 
 print ".". Is this typical?

On Windows, yes. You will get varying results on anything. It's a 
non-real-time multitasking thing.

sure, I would expect some variation, but this seems a bit large

anyhow, this should be averaged over thousands of executions to get 
a more accurate value

Anything that requires traditional I/O (not OpenGL or DirectX) will 
have a lot of variation on Windows. Video games use timers and delays 
to get consistent behavior.

adrian, its up to you to put a loop in the block.

but, you can get a feel for relative speeds.... sine, on my system 
takes a little over 0.000015 seconds on average.  when I run the 
timer with a loop of 100000 It takes about 1.5 seconds... so the 
resolution of the timer is factual.

I'm using the timers to have much better resolution in controling/measuring 
frame rates.

its not perfect, because the time events aren't very reliable, but 
at least I can measure some of mouse events and throttle them.

does chrono-time work for you?

I get:
** Script Error: vin has no value
** Where: chrono-time
** Near: vin ["chrono-time()"] 
vout 
GLOBAL_CHRONO-TIMED +

ohhh.... forgot to remove the call to 'VIN part of another library 
(also on rebol.org)

btw, how come you didn't want to use 'dt for 'time-lapse as in R3?

this could be part of 22-forward, I would think - at least for windows

i don't like acronyms like that.  I could have used time-delay   
but  time lapse is actually more precise meaning, especially when 
speaking about chronometers.
