LifeKraze is an exciting new social networking platform that combines the real world and the world offline. “Make real connections, generate real competition, create real challenges, and earn real rewards.”

The idea behind LifeKraze was born from Ben Wagner and David Nielson’s days in college. After graduation, they have built a strong team by adding Michael Brooks and a solid, experienced board to assist them in making this venture highly successful.

LifeKraze partnered with 2 companies to be a part of their team: Blacksnow Media and Tubatomic. Tubatomic designed and built the company’s corporate site and did the designs for the primary LifeKraze system. Blacksnow Media’s responsibility has been to construct the full and mobile site along with assisting in some of the design. Being a part of a winning combination of partners along with an all Chattanooga team has been very rewarding.

We are completing the final phases of development with our eyes on a successful launch in January. Alpha testing continues to give excellent feedback and is generating a lot of excitement among the user community. Stay tuned to LifeKraze’s official Beta launch in January so that you can participate in this new social networking community.

Facebook Connect opened the door for us to bring Knetwit to the Facebook community. With FB Connect we’ve streamlined sign-ups, invitations and content promotion for Facebook users. FB Connect gave Knetwit users more power to interact with their existing users and friends.

DateTime datatypes within WHERE clauses frequently give people the wrong results. I see this often. I am having to fix a lot of reports now to correct this issue. Here is the offending statement:

WHERE CreatedDate between @BeginDate and @EndDate

By default, a datetime value will give the time portion of “00:00:00″; the full value looks like this – “1/30/2009 00:00:00″.

See the problem with this WHERE statement – “WHERE CreatedDate BETWEEN ‘1/1/2009 00:00:00′ AND ‘1/30/2009 00:00:00′”? The problem is that you will not get data for the date of January 30th since that value is only up to midnight on the 30th.

Here are two ways of fixing it. Both of these methods depend on the programmer modifying the @EndDate parameter.

WHERE CreatedDate BETWEEN ‘1/1/2009 00:00:00′ AND ‘1/30/2009 23:59:59′.  --This takes you to the end of the day on the 30th.

WHERE CreatedDate BETWEEN ‘1/1/2009 00:00:00′ AND ‘1/31/2009 00:00:00′  --This takes you to the start of the next day.

An easy fix for this (examples are using Transact SQL) is the following:

WHERE CreatedDate BETWEEN @BeginDate and ADDDATE(day,1,@EndDate)

There are numerous solutions to load-balancing with Glassfish clusters and special ‘Sticky Glassfish Clusters’. Upon research this seemed to be the most common answer to our trouble, but it introduced more variables into the transition that we did not want to deal with. In the end we set our

 config.action_controller.session_store = cookie_store

and we were back in business. This was a very simple solution to our problem. Hopefully this helps someone else transitioning to JRuby/Glassfish.

The Libertarianism site is controlled by a back end CMS (Content Management System). An administrator can control content, categories, images, files, etc. that exist through out the site. This keeps the site fresh with content.
