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.

WebHome : Welcome to the home of the Software Web at brayden.org.

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 .

WorkFlow :

TOC: No TOC in "Software.WebCdf"

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

MerbDataMapperOnWindows :

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

First, you will need a compiler:

... elided ...

Then follow the instructions at nuance9, but just leave off the sudo:

... elided ...

Note that in the install of fastthread I chose the 'ruby' option - you can choose the win32 option and avoid building anything at that step.

Just to be sure, I also updated my json install:

... elided ...

By the way, I tried building the native extensions for json by selecting option 2 json 1.1.1 ruby above It was a dismal failure, with multiple invalid cl arguments, missing libs, etc. I didn't take the time to track that down, since I assume many people have run into the problem and if the problem is not fixed it's because the json developer doesn't have the time or interest. The mswin32 version installs just fine, as shown.

SplineFunctions :

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 .

... elided ...

The Bij are blending functions defined as:

... elided ...

In practice you select a set of uk and draw straight lines between them. By selecting the number of such points to be large enough 10 is more than enough for most applications the curve will look good. This also says that you can pre-compute the Bij uk and cache those values in a table, for better performance it matters, believe me .

StatisticsLib :

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