I have some measured success. I was able to get a C program to work at capturing a frame from a webcam in both Java and Ruby, the big problem is is memory.
So I went back to JFM (Java Media Framework) but I am having all kinds of inconsistent issues. Sometimes it works with Groovy, [...]

I was struggling for a bit on languages, which one to use, there are so many, do I use PHP, Ruby, Groovy, Python, or Jython or JRuby. I have settled on them let me summarize:

PHP - All my web programming will be in this language and my own custom framework.
Java - All my AI & [...]

I was doing some benchmark testing on my robotics programs for vision testing and I got some interesting results. For the most complicated program Java took 5312ms, Groovy took 5453ms, and JRuby took 5531ms.
I was amazed at how close they were given that all the computer shootouts say that Groovy is slow and JRuby is [...]

I actually created this to automate the cut and paste of text from the web to a word document for consumption by my “plain-text-challenged” customers.

require ‘win32ole’
word = WIN32OLE.new(’word.application’)
word.visible = true
word.documents.add
word.selection.typetext(”Hello World!\n”)

I was working with some scripts for having my PC talk. The first one is in Ruby:

require “win32/sapi5″
include Win32
v = SpVoice.new
v.Speak(”this is the easiest thing to do since I have started working with ruby..”)
Now this one in PHP:
<?php
$tts = new COM(”SAPI.SpVoice”);
$tts->speak(”this is a test”);
?>

I wanted a fast way to get data from mysql using ruby. after i installed the mysql gem it was really easy. This program gets all rows, but only displays the id,name and zip.

require “mysql”

dbh = Mysql.real_connect(”localhost”, “root”, “password”, “scottwork”)
res = dbh.query(”SELECT name,address,city,state,zip,email FROM contacts”)

while row = res.fetch_row do
id = row[0]

I did this using the rubygem Java-Ruby-Bridge. I did this because I was having problems with JRuby and wanted to execute my class from within Ruby.
Here is a simple way to do it, as long as you remember the classpath.
require ‘rjb’
Rjb::load(classpath = ‘../../TestJava/bin’, jvmargs=[])
test = Rjb::import(’Test’)
c = test.new
c.foo3
This way I was able to invoke a [...]

I have been doing a lot of web automation these days for testing and automating web based applications without APIs.
To open Internet Explorer with Ruby just use OLE.
require ‘win32ole’
ie = WIN32OLE.new(’InternetExplorer.Application’)
ie.visible = true
ie.gohome

Here I am going to talk about how to get images and text from the web with Ruby.
I have found a lot of useful informaiton on the web but sometimes it’s too hard to get it without some help. To help me out I created two little snips…
To get text:
require ‘uri’
url = ARGV[0]  # for [...]

First you will need to Install Ruby. Make sure the {ruby install path}/bin is in your path. Then run this script.

require ‘win32ole’
outlook = WIN32OLE.new(’outlook.application’)
outlook.quit

I used this in conjunction with my backup script by making sure to close Outlook before I started a backup, this way I was sure to get the Outlook files (.pst) backed up with [...]
