Yesterday, I lectured on environmental technologies and had a chance to present, what I think is, one of the most useful ,open source downloads for people who use Vista on their laptop.

A few months ago, my friend Tamir Khason has released a super cool open source application called Vista Battery Saver.

Today I participated and lectured at an open source event. It was great to meet enthusiastic people that believe in something bigger then themselves. These events are always a mixture of young people full of vigor and need for rebellion as well as more balanced older people that have believed in open source for a long time.

I have been intrigued with open source and open source business models for a long time now, so I might belong to the second group.

Lately, I seem to have a problem log-in into Gmail from my Internet Explorer, this happens both at work (IE over Vista) and at home (IE over XP). 

I get this wonderfully informative error message: 

Doing a couple of "refresh" helps sometimes.

But what really helps is using FireFox instead of Internet Explorer- This problem does not happen in FireFox.

Release 1.1 adds a fully functional JAVA server-side implementation to the pre-existing PHP server-side implementation. Now, Ajaxdo, AJAX

A friend asked me the other day: “I heard you work for an open source company, must be frustrating not making money from your code... how can you make money if you give away your code and IP?”

Well, I have been asked this question many times, and it is time I put my answer in writing:

You do not make money out of open source. You can, however, use open source to create profitable revenue channels and sell other products and services that are related to open source.

There are at least three revenue models based on open source leveraging:

Why is Java-enabled hosting so expensive? -
Hosting a website is a cheap matter these days. One could get a fairly good shared hosting package for around 1.5-6$ per month. These hosting packages offer a wide variety of features including support for PHP, PERL on LINUX or ASP (or ASP.NET) on Windows and MySQL DB. The problem is that prices soar when you want JSP/Servlet support.

I just re-created this site using Drupal open source project . It is super easy and very cool to configure. It is also very well supported in the forum and I found all the answers to my questions on site. Thanks Drupal !!

Release 0.1 contains a dynamic properties file that can monitor its source configuration file and reload whenever it is modified. It also provides the ability to register listeners that are notified when properties change.
