Here’s a small sample of the products that are available:

Playing Fair was developed using 100% open source software, including Python, Satchmo, and runs on an Ubuntu Linux server.

Well, Fred Marks, I am truly honoured to have come to the attention of your web scraping bot. This is clearly a defining moment in my career, to have been recognised by a vanity publisher, so I will immediately part with some of my money.

You use the Lock command to prevent multiple processes from updating the same record at the same time. But it only works by convention: all the code throughout an application that updates a given global must try to Lock the record that is to be updated, and unLock it when finished. If one routine uses Lock, but another doesn’t, nothing prevents the second routine from updating the record while the first routine has it locked.

Create a class:

Class aaaCarloTest.TestClass Extends %Persistent [ ClassType = persistent, ProcedureBlock ]
{
	ClassMethod myexecute(Command as %String)
	{
	XECUTE Command
	}
}

Now we can eval an ObjectScript command from Python:

import intersys.pythonbind

user="_SYSTEM";
password="SYS";
host = "192.168.100.1";
port = "1972";

url = host+"["+port+"]:USER"

conn = intersys.pythonbind.connection()
conn.connect_now(url, user, password, None)
database = intersys.pythonbind.database(conn)

print database.run_class_method("aaaCarloTest.TestClass","myexecute",['WRITE "Did this work?"'])

For example, running the routine aaaCarlo in the Caché terminal looks like this:

USER>DO foo^aaaCarlo
Here we go

USER>

Now we can do this from the IPython prompt:

In [10]: database.run_class_method("aaaCarloTest.TestClass","myexecute",['DO foo^aaaCarlo'])
Here we go

Literate programming. Anyone for some illiterate programming?

Natural parenting. Red food colouring makes kids happy, right?

Structured programming. Let’s use goto statements everywhere!

Anyone know some more examples?
