Sinax

Everyone’s favourite programming language – yes I am talking about Python – has been powering software in it’s trustworthy 2.x series for some years now.

It’s been already over a year since Python 3.0 was released (December 3rd 2008 to be excact), so it’s about time you took a look this evolution.

Plenty of books and websites, but here are my favourite sources for evolving to Python 3:

• Dive Into Python 3: http://diveintopython3.org/
• The official Python 3 documentation: http://docs.python.org/py3k/

An excellent introduction to Dependency Injection (DI) and Aspect Oriented Programming (AOP) can be found in the first chapter of the new ‘Spring in Action‘ book.

The first chapter can be downloaded for free and gives an excellent introduction to this powerful new programming approach.

The vSphere SDK for Perl provides an easy-to-use Perl scripting interface to the vSphere API. Administrators and developers can work with vSphere API objects using vSphere SDK for Perl subroutines. Administrators can use the utility applications included with vSphere SDK for Perl. In addition, the vSphere SDK for Perl includes the Web Services for Management component for writing scripts that retrieve CIM data from the ESX/ESXi host using CIMOM, a service that provides standard CIM management functions. The vSphere SDK for Perl also includes subroutines for managing the VMware Credential Store and an example application that illustrates credential store use.

If you’ve already made the switch to Ubuntu 10.04, the Lucid Lynx you will no doubt have cursed at the switched window button layout (you know, close, minimize and maximize).

Ubuntu 10.04 aka Lucid Lynx was released!

As usual, you can download this spanking new release from the Ubuntu mirrors or follow these instructions to apt-get upgrade your way into this exciting new release!

If you ever messed up and lost your SSH public key (~/.ssh/id_rsa.pub) but still have your private key (~/.ssh/id_rsa) you can easily recreate your public key with the following command:

-- michael@winston 10-Apr-10 18:15
-- ~:$ ssh-keygen -y > ~/.ssh/id_rsa.pub

This will read your private key and recreate the public key.
More useful gems in the ssh-keygen man page (like changing your passphrase, etc).

I’ve published a preliminary version of the documentation I’m writing for the Sinax Framework. All new content can be found here: http://www.sinax.be/software/sinax-framework/

I’ve just uploaded some new work on Sinax-Framework ORM and a new sample for the SXModel class.

Defining a model that maps to a database table is fairly straightforward. Simply subclass the SXModel class (or work on an instance) and map the properties of the model to the fields of the database.

The forms component of the Sinax-Framework is designed to facilitate working with forms and fields.

Below is a sample that you can also find in the Sinax-Framework source tree. It creates a simple form containing three fields, two regular SXTextField and one SXEmailField.
