Google recently made public their chart creation api . Very simple, very cool. The idea is that you specify chart data and settings in a url, and get back a generated image.

I wrote a little code that renders sparklines-like graphs using the google charts api, from TWiki. In my case I call the code from one of my plugins - but I'm probably the only person on the planet that uses that plugin, so you would need to call it from somewhere else.

The basic idea is simple: create the simplest, smallest legible line graph for a set of data. Small enough that it can serve as just another 'word' in a sentence, yet convey a relatively large set of quantitative information.

See the web site map or an alphabetical list of pages for help in navigating this web.

It's been a long while since I've maintained this part of my site. I'm thinking about just making it go away until I can figure out what should be here Nov 24, 2007 .

However, for now here's December 2007 .

TOC: No TOC in "Software.WebChanges"

Workflow management systems are a kind of holy grail among software developers. Such systems have the promise of subsuming more specialized types of applications, such as project tracking, bug tracking, etc. In fact, there's scarcely any business application that could not be integrated with, or made part of, a work flow management system.

I think the 2 main characteristics of work flow management systems that I find interesting are

1. They are a challenge to design and build, because they need to be able to integrate with a wide array of existing systems and must support a wide range of work flow activities
2. They have the potential of making a lot of money for the developer

Pretty painless overall. Here's a transcript and some notes.

First, you will need a compiler:

I've posted a set of classes and methods for generating combinations and permutations .

WebNotify is a subscription service to be automatically notified by email when topics change in the TWiki.Software web. This is a convenient service, so you do not have to come back and check all the time if something has changed. To subscribe to the service, please put yourself on the list below. The format is: 3 spaces   Main.yourWikiName - yourEmailAddress

Main.DaleBrayden - dalebrayden12345.org

Note: It is helpful to insert your name in alphabetical order by first name -- ignore the "Main." -- then you can find your name or not more easily if you wish to remove it or confirm that you are on the list.

This is a description of a class of cubic spline functions that have the property that the endpoints of the curve will pass through the first and last control points, and will pass near the interior control points.

I've provided an implementation in ruby see bottom of this page .

Let {Pi : i=1,N; N= 4} be the set of control points Let P0 = P1 and PN+1 = PN

I've posted a statistics package written in ruby . The source can be downloaded as a zip file

The INCLUDE directive is documented at TWiki.IncludeTopicsAndWebPages. Here are the main ways to use it:

You can include one twiki topic within another . That's how I do the WebRss pages - the RSS feeds at this site and also most of the content at Random.MonthlyDigest:
