[REBOL] Interesting Tech Developments
From: edoconnor:gma:il at: 16-Dec-2007 10:42
A couple of really interesting releases took place this week. You've
probably read about them already, but here they are:
1. Amazon SimpleDB
http://www.amazon.com/gp/browse.html?node=342335011
Some quick overview details here:

Here's what Dave Weiner has to say about it:

Key point, the wall is gone, replaced with a ramp. If you coded your
database in Amazon to begin with you will never see the wall. As you
need more capacity you have to do nothing, other than pay your bill.
... The design of Amazon's database is remarkably like the internal
data structures of modern programming languages. Very much like a hash
or a dictionary (what Perl and Python call these structures) ... In
this way it's like XML. I imagine all languages have had to
accommodate this feature of XML, so they should all map pretty well on
Amazon's structure
2. Google Charts
http://code.google.com/apis/chart/
Pretty simple on-the-fly .png chart creation, just construct the data
for the chart in an HTTP GET. A sample call looks like:
http://chart.apis.google.com/chart?cht=p3&chd=s:Uf9a&chs=250x100&chl=REBOL|Python|Perl|Ruby
IIRC, the ceiling on chart requests is 50,000 per day.
