		<description><![CDATA[I just self published this brand new book and I&#8217;m making its PDF available for (free) download on my web site. My goal is to explain some very basic fundamentals of computer science to kids who are starting to learn about computers at school and/or at home. For the tiny hints of programming, I referenced [...]<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=lessaworld.wordpress.com&amp;blog=1498865&amp;post=8&amp;subd=lessaworld&amp;ref=&amp;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Here&#8217;s another interesting problem that I solved. This one relates to SQL Server. The problem: To write a single database query that would allow me to get multiple row counts depending on certain pre-defined conditions. Let me make it clear &#8230; I had a table called nodes and I needed to count how many times [...]<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=lessaworld.wordpress.com&amp;blog=1498865&amp;post=6&amp;subd=lessaworld&amp;ref=&amp;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[For those who keep sending me emails and asking if the iTraceYou.com will ever come back &#8230; I think the most sincere answer is &#8230; no. I don&#8217;t think there is a market momentum for that service anymore. 6 years ago, definitely. Today &#8230; not really. With that said, I decided to start publishing and [...]<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=lessaworld.wordpress.com&amp;blog=1498865&amp;post=5&amp;subd=lessaworld&amp;ref=&amp;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[Just recently I came across this request to shift an entire slice of an array while keeping the algorithm cost to its bare minimum. Let&#8217;s put it this way. It&#8217;s pretty simple if you have something like ABCDE and you want to shift the elements so it becomes CDEAB. Now, the big problem is this [...]<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=lessaworld.wordpress.com&amp;blog=1498865&amp;post=3&amp;subd=lessaworld&amp;ref=&amp;feed=1" width="1" height="1" />]]></description>
