World: r3wp

Almost there: Twitter API client using OAuth (Basic Auth is being 
turned off).  Only thing I can't get working is signing a POST request 
with a body (which sucks for sending updates):

	http://www.ross-gill.com/page/Twitter_API_and_REBOL


I've tried using my rest:// protocol and the currently published 
version uses Graham's HTTP modifications (regular HTTP does not work 
as you can't use custom headers with a GET request).


Aside from that, the GET requests work, as does the authorization 
process.  Any observations welcome.

Precise timing for R2 using kernel32.dll functions on Windows

http://www.rebol.org/view-script.r?script=windows-chrono.r


there is a 'TIME-LAPSE function, and a 'CRONO-TIME function.   the 
later isn't completely aligned with the NOW function (a few milliseconds 
off IIRC), but it is very precise from one call to the next.


some might also find the 'i64-TO-FLOAT function (and related i64-struct) 
usefull for converting 64bit integers (stored as structs of two integers) 
into decimal! values.


many window functions use 8 byte long unions (64 bits) as arguments 
for return values and they are very complicated to use because REBOL 
only supports signed ints.  this makes it much easier to implement 
routines for those functions.

Max, maybe you can update the script so that it looks in the system 
directory for kernel32.dll - i.e. %systemroor%/system32

systemroot is the environment variable for the windows directory

systemroot, I meant

as it is, the loading of the dll failed for me

what OS version?

win 7 64 bit - but systemroot is common to all

the script resolved the directory for kernel32.dll to the directory 
of the rebol executable

probably since the system32 isn't in the paths of the 64 win7

and with the system32 it worked?

I mean with your suggestion... it worked?

how would I get the value of  %systemroot% ... it doesn't seem to 
be valid within a rebol path.

(lets move to ann-reply)

windows-chrono.r updated on rebol.org with better windows dll path 
resolution and bug fixes

Added markers to my Google Charts script: http://www.ross-gill.com/r/google-charts.r

I feel like the addition is a bit messy, so ymmv.

	chart [data: [1 2 3 4]] ; basic usage
	chart [
		size: 200x200
		data: [
			[10 30 50 70 90]
			[30 40 50 60 70]
			[70 60 50 40 30]
			[90 70 50 30 10]
		]
		offset: 0
		markers: [
			financial 0.0.204 0 1x-1 20
		]
	]

If you use it, let me know how it goes.

'tweet function for posting to Twitter: http://www.ross-gill.com/r/tweet.html

Usage:


 do/args http://www.ross-gill.com/r/tweet.r[... keys/secrets per 
 settings ...]
	tweet "Status Update"


You can either do/args, or download the script and modify the header. 
 Caveat: you'll need the Application Key/Secret (obtained from the 
Twitter Dev Site) and the User Key/Secret (you'd have to do the handshake 
to get these, see my %twitter.r page: http://www.ross-gill.com/page/Twitter_API_and_REBOL).


Use at your own risk, you would not want to share any of the keys/secrets.

Upgraded R3 on http://tryrebol.esperconsultancy.nlto A107

Looks like we need to remove that "Loading boot extensions..." line?

That wouldn't hurt :)

Coming Friday I will be presenting two talks on Software Freedom 
Day 2010 at the CWI in Amsterdam, the Centre for Mathematics and 
Computer Science, where Python was created:

http://www.softwarefreedomday.eu

One presentation will be about Boron and how it relates to REBOL. 
I will demonstrate building a website with Boron on the Cheyenne 
server:

http://www.softwarefreedomday.eu/2010/Kaj-de-Vos-Boron-programming-language-2010.html

The other talk is about the system that I will be using for the presentations: 
a graphical development version of Syllable Server running the ROX 
Desktop, which is written in Python:

http://www.softwarefreedomday.eu/2010/Kaj-de-Vos-Syllable-Server-ROX-Desktop-2010.html

really cool... will these be available as vids after?

Yep

nice!

Max, you understand spoken Dutch?

no, it says presentations will be in english

Mine, double yep

Specially for you :-)

Kaj, how did the Syllable conference go on September 4th? Will there 
by any videos posted?

Replying in Syllable group

particle generator online.


built for fun and as a reference for anyone to implement his own 
.... its on rebol.org.  have fun hacking/improving it.

pictures: 

http://www.rebol.org/view-script-images.r?script-name=fire-smoke-particle-generator.r


run script:

 do http://www.rebol.org/download-a-script.r?script-name=fire-smoke-particle-generator.r

looks like grayscale soap bubbles!

when scaled yeah.  but when far & animated and especially when you 
adjust the opacity to be just right wrt rate, its not that bad.

animation makes a big difference

new version on-line.  with better flames and a few more options (like 
auto-saving the setup on exit and allowing you to remove particle 
generators, by ctrl-clicking on them)


the default setup is also much better, and leverages the better flames.

That is really cool!

thanks!  


to you and everyone else who takes the time to run it, it makes the 
time spent building it worth a little  :-)

nice !

I upgraded http://tryrebol.esperconsultancy.nlto the latest version 
of my CMS

It doesn't really affect the site yet, but there's an extra year 
of development in there

I've published my Boron presentation from Software Freedom Day:

http://tryrebol.esperconsultancy.nl/Boron

It demonstrates building a dynamic website with the presentation 
on Cheyenne, so there are also a Cheyenne demonstration and a small 
CMS and presentation program in there

Very cool, Kaj.
